It is necessary to examine this many cells in order to detect clinically significant mosaicism erectile dysfunction pills walmart 40/60mg levitra with dapoxetine. Each chromosome can then be arranged in pairs according to size and banding pattern into a karyotype erectile dysfunction treatment definition levitra with dapoxetine 20/60mg. The karyotype allows the Cytogeneticist to even more closely examine each chromosome for structural changes erectile dysfunction prevents ejaculation in most cases discount levitra with dapoxetine 20/60mg amex. A written description of the karyotype which defines the chromosome analysis is then made cough syrup causes erectile dysfunction order 20/60 mg levitra with dapoxetine. Genes are located on specific regions of a certain chromosome impotence when trying for a baby cheap 40/60mg levitra with dapoxetine amex, termed the gene locus (plural: loci) erectile dysfunction doctors in charleston sc 40/60mg levitra with dapoxetine amex. Linkage groups are invariably the same number as the pairs of homologous chromosomes an organism possesses. Recombination occurs when crossing over has broken linkage groups, as in the case of the genes for wing size and body color that Morgan studied. Chromosome mapping was originally based on the frequencies of recombination between alleles. In dihybrid testcrosses for frizzle and white in chickens, Hutt (1931) obtained: frizzled is dominant over normal (if one combines slightly and extremely frizzled). P1: White, Normal Colored, Frizzle F1: White, Frizzle Testcross: White, Frizzle (F1) x Coloured,Normal Counts in testcross 1 (Hutt 1931) White Coloured Total Frizzled 18 63 81 Normal 63 13 76 81 76 157 Note the marginal counts are in the 1:1 ratio we expect, but there is deviation in the main table from 1:1:1:1. This is what is referred to as repulsion of the dominant traits (frizzled and white) in the first case, and coupling in the second. The percentage deviation from 1:1:1:1 seems to be about the same in each table, but in opposite directions. Actually, we always ignore the sign, and calculate the recombination in this table as 100*(4+2)/33=18. If one examines a large number of genes in such a fashion in any organism, sets of genes are always linked together, while assorting independently (recombination 50%) with respect to members of other linkage groups. It 128 Molecular Biology and Applied Genetics was realised in the 1920s that each linkage group corresponds to a chromosome. Mapping If one can arrange testcrosses for triple (or higher order) heterozygotes and recessives (a three-point cross), the recombination can be calculated for the three pairs of genes. The data will look like this example: Trait A is controlled by a gene with alleles A and a, A dominant to a Trait B is controlled by a gene with alleles B and b, B dominant to b Trait C is controlled by a gene with alleles C and c, C dominant to c Testcross is AaBbCc x abc/abc 129 Molecular Biology and Applied Genetics Data from three-point cross of corn (colourless, shrunken, waxy) due to Stadler. Progeny Phenotype Count 1 A B C 17959 2 a b c 17699 3 A b c 509 4 a B C 524 5 A B c 4455 6 a b C 4654 7 A b C 20 8 a B c 12 Total tested 45832 the table deviates drastically from the expected 1:1:1:1:1:1:1:1, so linkage is being observed. The linkage map that one constructs using recombination distance turns out to correspond to the physical map of genes along the linear structure of the chromosome. Abbreviated linkage map of maize chromosome 9 (Brookhaven National Laboratory 1996). Since "gene" can be taken to mean the different gene forms (alleles), or the factor controlling a phenotype, geneticists often refer to the latter as the locus sh1, rather than the gene sh1. If we had been looking only at dihybrid test cross data, then we would not be able to detect these double recombinants. One notices that double recombinants are not very common, so the effect on the estimates of the percent recombination is not large. The corollary of this is that most chromosomes will experience only zero or one recombinants. The estimated double recombination rate does add to our estimate of the distance between the more distant loci (A and C in the example). Interference the term interference refers to the fact that recombination seems to be suppressed close to a first 133 Molecular Biology and Applied Genetics recombination event. The coincidence coefficient is the ratio of the observed number of double recombinants to the expected number. For a given distance between two loci, one can estimate the number of double recombinants that one would expect. Then we would expect in 1% of cases that a double recombinant would occur (one in each interval). The expected frequency of double cross overs is thus is the product of the observed frquencies of the ingle crosses overs. Interferences is calculated as I = 1-c where, I = Index of interference c = Coefficent of coincidence c = Observed frequency of Double Cross overs Expected frequency of Double Cross overs 134 Molecular Biology and Applied Genetics 6. Deriving Linkage Distance and Gene Order from Three-Point Crosses By adding a third gene, we now have several different types of crossing over products that can be obtained. Now if we were to perform a testcross with F1, we would expect a 1:1:1:1:1:1:1:1 ratio. As with the two point analyzes described above, deviation from this expected ratio indicates that linkage is occurring. Once we have determined the parental genotypes, we use that information along with the information obtained from the double-crossover. The next important point is that a double-crossover event moves the middle allele from one sister chromatid to the other. This effectively places the non-parental allele of the middle gene onto a chromosome with the parental alleles of the two flanking genes. We can see from the table that the C gene must be in the middle because the recessive c allele is now on the same chromosome as the A and B alleles, 137 Molecular Biology and Applied Genetics and the dominant C allele is on the same chromosome as the recessive a and b alleles. The linkage distance is calculated by dividing the total number of recombinant gametes into the total number of gametes. This is the same approach we used with the two-point analyses that we performed earlier. For these calculations we include those double-crossovers in the calculations of both interval distances. What is different from our first three-point cross is that one parent did not contain all of the dominant alleles and the other all of the recessive alleles. As we mentioned above, the least frequent genotypes are the double-crossover geneotypes. From this information we can determine the order by asking the question: In the double-crossover genotypes, which parental allele is not associated with the two parental alleles it was associated with in the original parental cross. Three-point crosses also allows one to measure interference (I) among crossover events within a given region of a chromosome. Specifically, the amount of double crossover gives an indication if interference occurs. The concept is that given specific recombination rates in two adjacent chromosomal intervals, the rate of double-crossovers in this region should be equal to the product of the single crossovers. The formula is as follows: For the v ct cvdata, the interference value is 33% [100*(8/12)]. Values less than one indicate that interference is occurring in this region of the chromosome. When analyzing a segregation ratio of phenotypes in one populaton, what result suggests that two genes are linked on the same chromosome In Drosophila, b is the allele for normal body color and at the same gene b is the allele for black body color. A cross is made between a homozygous wild type fly and fly with black body and vestigial wings. The following segregtion ratio was observed: 143 Molecular Biology and Applied Genetics Phenotype # Observed Wild Type 405 Normal, vestigial 85 Black, normal 100 Black, vestigial 410 Are these two genes linked How do you recognize double cross progeny when analyzing the segregation data of three genes in a population Introduction A pedigree is a diagram of family relationships that uses symbols to represent people and lines to represent genetic relationships. These diagrams make it easier to visualize relationships within families, particularly large extended families. Pedigrees are often used to determine the mode of inheritance (dominant, recessive, etc. If more than one individual in a family is afflicted with a disease, it is a clue that the disease may be inherited. A doctor needs to look at the family history to determine whether the disease is indeed inherited and, if it is, to establish the mode of inheritance. This information can then be used to predict recurrence risk in future generations. A basic method for determining the pattern of inheritance of any trait (which may be a physical attribute like eye color or a serious disease like Marfan 146 Molecular Biology and Applied Genetics syndrome) is to look at its occurrence in several individuals within a family, spanning as many generations as possible. For a disease trait, a doctor has to examine existing family members to determine who is affected and who is not. The same information may be difficult to obtain about more distant relatives, and is often incomplete. Subsequent generations are therefore written underneath the parental generations and the oldest individuals are found at the top of the pedigree. If the purpose of a pedigree is to analyze the pattern of inheritance of a particular trait, it is customary to shade in the symbol of all individuals that possess this trait. It is usually unaware of the existence unless a variant form is present in the population which causes 148 Molecular Biology and Applied Genetics an abnormal (or at least different) phenotype. One can follow the inheritance of the abnormal phenotype and deduce whether the variant allele is dominant or recessive. Using genetic principles, the information presented in a pedigree can be analyzed to determine whether a given physical trait is inherited or not and what the pattern of inheritance is. Characteristics of a dominant pedigree are: 1) Every affected individual has at least one affected parent; 2) Affected individuals who mate with unaffected individuals have a 50% chance of transmitting the trait to each child; and 3) Two affected individuals may have unaffected children. Penetrance and expressivity Penetrance is the probability that a disease will appear in an individual when a disease-allele is present. For example, if all the individuals who have the disease causing allele for a dominant disorder have the disease, the allele is said to have 100% penetrance. If only a quarter of individuals carrying the disease-causing allele show symptoms of the disease, the penetrance is 25%. Expressivity, on the other hand, refers to the range of symptoms that are possible for a given disease. For 150 Molecular Biology and Applied Genetics example, an inherited disease like Marfan syndrome can have either severe or mild symptoms, making it difficult to diagnose. Other factors that can cause diseases to cluster within a family are viral infections or exposure to disease causing agents (for example, asbestos). The first clue that a disease is not inherited is that it does not show a pattern of inheritance that is consistent with genetic principles (in other words, it does not look anything like a dominant or recessive pedigree). Autosomal dominant A dominant condition is transmitted in unbroken descent from each generation to the next. Therefore, it is expected that every child of such a mating to have a 50% chance of receiving the mutant gene and thus of being affected. A typical pedigree Examples of autosomal dominant conditions include: Tuberous sclerosis, neurofibromatosis and many other cancer causing mutations such as retinoblastoma 7. If it is a severe condition it will be unlikely that homozygotes will live to reproduce and thus most occurences of the condition will be in matings between two heterozygotes (or carriers). Then there will be a chance that any 152 Molecular Biology and Applied Genetics child will be affected. The degree of risk that both alleles of a pair in a person are descended from the same recent common ancestor is the degree of inbreeding of the person. Considering any child of a first cousin mating, one can trace through the pedigree the chance that the other allele is the same by common descent. A total risk of x x x = 1/16 154 Molecular Biology and Applied Genetics. Once phenotypic data is collected from several generations and the pedigree is drawn, careful analysis will allow you to determine whether the trait is dominant or recessive. Mitochondrial inheritance Mitochondria are cellular organelles involved in energy production and conversion. A mitochondrial inheritance pedigree is that all the children of an affected female but none of the children of an affected male will inherit the disease. Uniparental disomy Although it is not possible to make a viable human embryo with two complete haploid sets of chromosomes from the same sex parent it is sometimes possible that both copies of a single chromosome may be inherited from the same parent (along with no copies of the corresponding chromosome from the other parent. The child had received two copies of the mutant chromosome 7 from the carrier parent and no chromosome 7 from the unaffected parent. The double helix structure is stabilized by base pairing between the nucleotides, with adenine and thymine forming two hydrogen bonds, and cytosine and guanine forming three. Base + Sugar = nucleoside Base + Sugar + Phosphate Group = nucleotide Attached to each sugar residue is one of the four essentially planar nitrogenic organic bases: Adenine A, Cytosine C, Guanine G, Thymine T, the plane of each base is essentially perpendicular to the helix axis. The two strands coil about each other so that all the bases project inward towards the helix axis. The two 164 Molecular Biology and Applied Genetics strands are held together by hydrogen bonds linking each base projecting from one backbone to its complementary base projecting from another backbone. This activity is an important process; several antibiotics exert their effects on this system, inhibiting prokaryotic enzymes more than eukaryotic ones. It is single stranded (with few exception: few virus) 168 Molecular Biology and Applied Genetics 3. This helps the prokaryotic cell respond quickly to a fluctuating environment and fluctuating needs. In other words the "adapter" molecule that converts nucleic acid sequence to protein sequence. All such media have certain common properties: > the molecule must be able to carry information: > the molecule must be able to hold information, without this property it is useless.

Randomization will be web-based erectile dysfunction exercises order genuine levitra with dapoxetine on line, using computer generated concealed tables (service provided by Nottingham University Clinical Trials Unit) erectile dysfunction after 80 purchase levitra with dapoxetine with american express. The authors stated that many studies have shown the effectiveness of regional blockade in neck of femur fractures erectile dysfunction medications injection order levitra with dapoxetine once a day, but the techniques used have varied erectile dysfunction normal testosterone effective 20/60mg levitra with dapoxetine. Infra-Orbital Nerve Blocks for the Management of Post-Operative Pain Following Cleft Lip Repair In a Cochrane review how to cure erectile dysfunction at young age purchase cheapest levitra with dapoxetine and levitra with dapoxetine, Feriani and associates (2016) evaluated the effects of infra-orbital nerve block for the management of post-operative pain following cleft lip repair in children protocol for erectile dysfunction generic levitra with dapoxetine 20/60 mg line. They searched for ongoing trials in the following platforms: the metaRegister of Controlled Trials; ClinicalTrials. These investigators checked reference lists of the included studies to identify any additional studies. They contacted specialists in the field and authors of the included trials for unpublished data. They considered the type of drug, dosage, and route of administration used in each study. Two review authors independently identified, screened, and selected the studies, assessed trial quality, and performed data extraction using the Cochrane Pain, Palliative and Supportive Care Review Group criteria. The authors concluded that there is low to very low-quality evidence that infra-orbital nerve block with lignocaine or bupivacaine may reduce post-operative pain more than placebo and intravenous analgesia in children undergoing cleft lip repair. No other significant difference between groups regarding pain during mobilization and at rest was found. These investigators sought unpublished studies from Internet sources, and searched clinical trials databases for ongoing trials. Two review authors independently considered trials for inclusion in the review, assessed risk of bias, and extracted data. They performed analyses using standard statistical techniques as described in the Cochrane Handbook for Systematic Reviews of Interventions, using Review Manager 5. These researchers identified 7 studies that met inclusion criteria for this review; 3 were recorded as completed (or terminated) but no results were published. No studies reported a health economic analysis or patient-reported outcome measures (outside of pain). They stated that further research is very likely to have an important impact on the confidence in the estimate of effect and is likely to change the estimate. However, they stated that further well-designed and adequately powered studies are needed to confirm its utility, particularly with respect to other regional anesthesia techniques. Ultrasound-Guided Forearm Peripheral Nerve Blocks for the Treatment of Digit Injuries. Although these orthopedic injuries are not complex, the 4-point digital block used for anesthesia during the reduction can be painful. Soberon and associates (2016) stated that limited data exist regarding the role of peri-neural blockade of the distal median, ulnar, and radial nerves as a primary anesthetic in patients undergoing hand surgery. In a prospective, randomized, pilot study, these researchers compared these techniques to brachial plexus blocks as a primary anesthetic in this patient population. The ability to undergo surgery without analgesic or local anesthetic supplementation was the primary outcome. The 2 groups were similar in terms of the need for conversion to general anesthesia or analgesic or local anesthetic supplementation, with only 1 patient in the forearm block group and 2 in the brachial plexus block group requiring local anesthetic supplementation or conversion to general anesthesia. The authors concluded that forearm blocks may be used as Proprietary 23/56 Nerve Blocks Medical Clinical Policy Bulletins Aetna a primary anesthetic in patients undergoing hand surgery. They stated that further research is needed to determine the appropriateness of these techniques in patients undergoing surgery in the thumb or proximal to the hand. Pain was measured using the numerical scale and the need for rescue analgesia was evaluated. The distribution followed the joint capsule without entering the joint, both in the femur and in the tibia. The authors concluded that the administration of 4 ml of local anesthetic at the level of the 4 genicular nerves of the knee produced a wide peri articular distribution. However, additional large-scale studies are needed to confirm their effectiveness and to quantify the risk of peri-foraminal vascular breach. Theoretically, the infraclavicular approach targets the posterior and lateral cords, thus anesthetizing the axillary nerve that supplies the anterior and posterior shoulder joint, as well as the subscapular and lateral pectoral nerves (both of which supply the anterior shoulder joint), whereas the suprascapular nerve block anesthetizes the posterior shoulder. The authors concluded that future randomized trials are needed to validate the effectiveness of combined infraclavicular-suprascapular blocks for shoulder surgery. These patients were divided into 2 groups: (i) control group (n = 30), patients received oral sulfasalazine treatment; and (ii) experimental group (n = 90), patients received stellate ganglion block treatment. Clinical symptoms and disease activity in these 2 groups were compared before and after treatment using endoscopy. After treatment, clinical symptoms and disease activity were shown to be alleviated by endoscopy in both the control and experimental groups. These researchers examined the etiology, epidemiology, presentation and treatment of common causes of neurogenic pelvic pain, including neuralgia of the border nerves (ilio-inguinal, ilio-hypogastric, and genito-femoral), pudendal neuralgia, clunealgia, sacral radiculopathies caused by Tarlov cysts, and cauda equina syndrome. In a randomized, double-blind, placebo-controlled, clinical trial, Rapp and colleagues (2017) examined if superior hypogastric plexus block performed during abdominal hysterectomy decreases post-operative opioid consumption and pain. Subjects were individually randomized to either intervention; subjects, caregivers, and those assessing the outcomes were blinded to group assignment. Analysis was performed on 35 women in the ropivaciane group and 33 women in the saline group. The post-operative opioid consumption was significantly lower in the ropivacaine group than in the placebo group (median of 55. Repeated measures were performed on pre-injection, and after injection at 1 hour, 1 week, and 1 month. Pain significantly decreased until a week after injection, but pain after a month was relatively increased. They stated that these limitations prevented an absolute determination of the effects of injection; broader and long-term follow-up studies are needed. A single blinded randomized controlled trial evaluating local anesthetic with steroids versus local anesthetic alone for transformed migraine reported slightly worse results with steroids, but there are several alternate explanations for this finding other than steroids being counterproductive. Dach et al (2015) noted that several studies have presented evidence that blocking peripheral nerves is effective for the treatment of some headaches and cranial neuralgias, resulting in reduction of the frequency, intensity, and duration of pain. The authors concluded that the nerve block can be used in primary (migraine, cluster headache, and nummular headache) and secondary headaches (cervicogenic headache and headache attributed to craniotomy), as well as in cranial neuralgias (trigeminal neuropathies, glossopharyngeal and occipital neuralgias). A total of 64 patients were mostly women (78 %) with an average age of 71 years (range of 65 to 94). Representative headache diagnoses were chronic migraine 50 %, episodic migraine 12. Common co-morbidities were hypertension 48 %, hyperlipidemia 42 %, arthritis 27 %, depression 47 %, and anxiety 33 %; 89 % were prescribed at least 1 medication fulfilling the Beers criteria. Numeric rating scale pain scores were recorded pre-injection and at 30 minutes, 2 weeks, and 4 weeks after injection. A total of 14 injections were performed with a mean Proprietary 29/56 Nerve Blocks Medical Clinical Policy Bulletins Aetna procedure time of 3. They stated that the results of this study provided important preliminary data for future randomized trials involving patients with occipital neuralgia and cervicogenicheadache. The position of M-A groove was constant on X-rays at each level of the lumbar spine. Confirming this position under the fluoroscope, the medial branch nerves can be blocked selectively. A 38-year old man presented with a 2-year history of incapacitating left suprascapular pain after a fall onto his out-stretched hand. The history and clinical examination was suggestive of myofascial pain affecting the trapezius muscle. There is currently insufficient evidence to support the use of spinal accessory neve block for treatment of neck pain and upper back pain. A catheter inserted into this plane can extend analgesic duration and can be an alternative to epidural analgesia. Management usually involves a multi-disciplinary approach that includes oral and topical analgesics, performing appropriate interventional techniques, and coordinating additional care such as physiotherapy, psychotherapy and rehabilitation. Most of these procedures are technically complex and are associated with risks and complications due to the proximity of the targets to neuraxial structures and pleura. The patients were followed-up by telephone 1 week after each block and reviewed in the clinic 4 to 6 weeks later to evaluate the analgesic response as well as the need for further injections and modification to the overall analgesic plan. Moreover, these researchers stated that further studies are needed to validate these findings. Yamak Altinpulluk et al (2018) noted that effective post-operative analgesia after emergency caesarean section is important because it provides early recovery, ambulation and breast feeding. This was a small (n = 6) study; and its findings were confounded by the use of multi-modal analgesia. Also, tramadol consumption and additional rescue analgesic requirement were measured. Hannig et al (2018) noted that post-operative pain after laparoscopic cholecystectomy can be severe. Despite multi-modal analgesia regimes, administration of high doses of opioids is often necessary. This will hinder early mobilization and discharge of the patient from the day surgery setting and is sub-optimal in an early recovery after surgery setting. Lastly, additives like glucocorticoids can be considered, which presumably would extend block duration beyond 24 hours. A total of 106 patients undergoing elective cardiac surgery with cardiopulmonary bypass were included in this study. However, its role is still being defined and randomized controlled studies as have been performed for pancreas cancer are lacking. Prospective, controlled, and comparative trials are needed to confirm the safety and assess the long-term efficacy of this approach to pain management compared with conventional techniques. These researchers found no significant differences in the 3 groups with regard to baseline patient demographics. However, the Proprietary 35/56 Nerve Blocks Medical Clinical Policy Bulletins Aetna consecutive enrollment of patients in this study may have limited selection bias. Because of the novel approach of this study, such information was not available, so this study could suffer from assignment bias. However, a strength of this study is that it allowed other investigator groups to validate these findings, and when needed, to use these findings to calculate a clinical delta for the appropriate sample size needed for a prospective randomized controlled trial. Patients in the intervention group were more satisfied, had less opioid consumption (p = 0. Nerve Hydrodissection for Peripheral Nerve Entrapment Nerve hydrodissection entails the injection of fluid. These researchers reported a case of sural nerve entrapment in a 34-year old male triathlete with a history of recurrent training-induced right-sided gastrocnemius strains. Orthopedic assessment showed worsening pain with forced passive dorsiflexion and manual pressure applied over the distal aspect of the gastrocnemius. The patient had complete relief of symptoms and full return to the pre-injury level of participation in competitive sports. It involves using an anesthetic or solution such as saline to separate the nerve from the surrounding tissue, fascia, or adjacent structures. Low-level studies showed some safety and effectiveness for the technique, but further research is needed. Popliteal Block for Open Reduction Internal Fixation of Ankle Fracture In a prospective randomized study, Goldstein et al (2012) compared post-operative pain control in patients treated surgically for ankle fractures who receive popliteal blocks with those who received general anesthesia alone. At 12 hours, there was no significant difference between the 2 groups with regard to pain control. However, patients who receive popliteal blocks experienced a significant increase in pain between 12 and 24 hours. Recognition of this "rebound pain" with early narcotic administration may allow patients to have more effective post-operative pain control. They found that popliteal block patients were no more likely to be discharged to home than those who received general anesthesia. Tsai et al (2010) noted that the saphenous nerve, a branch of the femoral nerve, is a pure sensory nerve that supplies the antero-medial aspect of the lower leg from the knee to the foot. Patient demographics and data were recorded, including block characteristics, intra-operative anesthetic management, pre-block, post-block, and post-operative pain scores, as well as post-operative analgesic dosing. Post-operative block success was defined by reduction of pain score to 0 without need for additional analgesic dosing. Moreover, they stated that a randomized prospective study would provide a more definitive answer regarding the efficacy of this technique for surgical anesthesia. Recently, his pain became worse even with imipramine 75-mg and carbamazepine 100-mg a day, which relieved effectively the patient from the pain for the last 3 years. Supraorbital and supratrochlear nerve blockade with modified van-Lint technique was planned, as the classical nerve block sites were covered with active vesicles. The block has been developed for post-operative pain control after gynecologic and abdominal surgery. Overall, the results were encouraging and most studies have demonstrated clinically significant reductions of post-operative opioid requirements and pain, as well as some effects on opioid-related side effects (sedation and post-operative nausea and vomiting). There was a trend toward superior analgesic outcomes when 15 ml of local anesthetic or more was used per side compared with lesser volumes.

Since temporary teeth are succeeded by perma Therefore eruption of teeth will be (rst) molar > (medial) nent teeth therefore they are called as sucessional teeth incisor > (lateral) incisor > (rst premolar) bicuspid > or succedaneous teeth. The age of eruption of permanent teeth After eruption of second molar, the mandibular ramus and their calcication of root is given in Table 3. This developing space is known as spacing for Features of Erupting of Teeth third molar. In some indi starting from 6 year of life (because rst permanent molar viduals it may erupt at time, in some it may be delayed or th erupt at 6 year) till 11 years of age (because the temporary in some it may not erupt at all! Therefore due precaution should be exercised permanent teeth while interpreting the third molar tooth. The teeth may Teeth Eruption Calcication of root remain impacted or may not erupt at all and the reasons are First molar 6-7 years 9-10 years given in Tables 3. The causes for early eruption Medial incisor 7-8 years 10-11 years of teeth are given in Table 3. In non-erupted third molar Lateral incisor 8-9 years 11-12 years with spacing, X-ray examination is warranted to access the First premolar 9-10 years 12-13 years condition of tooth. In case of impacted third molar, complete Second premolar 10-11 years 13-14 years calcication of root without eruption, age can be presumed Canine 11-12 years 14-15 years to be more than 25 years. Impacted tooth means tooth Second molar 12-14 years 14-16 years that do not develop in oral cavity but trapped in jawbone Third molar 17-25 years 20-23 years (Figs 3.

Appearance and Fusion of Ossication Centers Radiological survey of ossication centers may provide con siderable help in estimating age of a person. However, we cannot place too much reliance over such method as many factors affect the process of appearance and fusion of bone. Roughly this method provides one parameter in conjugation with others to deduce age of a person and it cannot be superior criteria when considered in isolation (Figs 3. Similarly it has to be remembered that the progression of fusion of bone is a process and not an event, so it may be liable for variation. Galstaun while studying Bengali population had complete eruption of third molar provided the data, which are given in Table 3. Radiographic Study of Diaphyseal Length 3) Changes in skeleton Hunt and Hatch had developed a method whereby they stud 4) Radiology ied the diaphyseal length of either femur or tibia to estimate age. Hoffmann is of the opinion that diaphyseal length is Physical Examination reasonable means of age estimation for individuals below 12 years especially when skeletons are devoid of epiphysial Depends upon the age, some changes initiates early at about ends or if dental data is missing. In advance age, ecchymoses may be observed in skin due to brittle and hardened vessels. Of all the above criteria, transparency of root alone is the single most impor tant one to determine age. For the purpose of estimation of age, a standard regression line was made and a formula provided to estimate age. The formula is: An + Pn + Sn + Rn + Cn + Tn = points > age in years Here n denotes number of points recorded. From the percentage of dots visible through Attrition tooth and actual number, the age of a person is estimated. Biochemical Method A-2 Attrition within dentine A-3 Attrition exposes the soft pulp of tooth Biochemical examination of tooth can provide age of a per son. When the amino Periodontosis acids are incorporated into teeth, they are of the Levo or left P-0 No Periodontosis handed variety. Once these amino acids have been xed in P-1 Exposure less than 1/3 of root near crown dentine they undergo a slow and irreversible change to dextro P-2 Exposure of root more than 1/3 but less than 2/3 or right-handed variety. The ration of levo and dextro amino P-3 Exposure more than 2/3 of root acids will give the age.
