European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 9, Pages 73-79

Age estimation plays a vital role in establishing the identity of the individual for the forensic expert especially in developing countries where birth records are not well maintained. In living it is not only important for identification but also for various civil and criminal purposes. Even the courts in India accept the ossification test as the reliable indicator of age as compared to physical and dental assessment of age.
This study comprised of 250 male subjects from Puducherry UT, India. The age group of the subjects ranged from 14 to 19 years. Radiographs of the right wrist joint with hand of these subjects were taken and the epiphyseal union of the centres at the wrist joint and hand were noted. The findings were compared with the recorded age given by various research workers.

Age being one of the primary characteristics in establishing the identity of the individual, its estimation becomes an important task for the forensic expert especially in developing countries where birth records are not well maintained. In living it is not only important for identification but also for various civil and criminal purposes. Even the courts in India accept the ossification test as the reliable indicator of age as compared to physical and dental assessment of age.
This study comprised of 250 female subjects from Puducherry region, India. The age group of the subjects ranged from 14 to 19 years. Radiographs of the right wrist joint with hand of these subjects were taken and the epiphyseal union of the centres at the wrist joint and hand were noted.

D. Angel Fastina Mary, Dr. Sangavi . R, Dr. Adimulapu Hima Sandeep

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 7, Pages 6996-7003

Background
Third molar mineralization has been utilised frequently as a forensic age determination technique. The creation of novel strategies is crucial because this technique is ineffective after the age of 18, particularly when determining whether a person is older than 21. For this, it has been advised that the periodontal ligament be visible.
Materials and Methods
Periodontal ligament visibility was assessed in the lower third molars, using a sample of 53 orthopantomogramme, 32 which belonging to females and 21 belonging to males, from a patient visiting the saveetha dental college and hospitals, Chennai from December 2021 to March 2022 aged 17 to 31 years. A classification of four stages based on the visual phenomenon of disappearance of the periodontal ligament of fully mineralized third molars was used. For each stage, median, variance, minimal and maximal age were assessed.
Results:
The relationship between age and stage of periodontal ligament had a statistical significance for both sexes. In this population, stage 3 can be used to state that a male person is over 20 years-old for females, another marker should be used.
Conclusion:
This method demonstrates reliability because there is a less significant relationship between the age of the person and the PDL visibility.

Background: Age estimation can be a critical part of Forensic investigations. The age has to be determined not only for identification purposes but also for various civil and criminal purposes. Age at which the epiphysis of bones fuse varies depending on health, hereditary, nutritional, endocrine and environmental factors affecting the people of the different regions, it cannot be reasonably expected to formulate a uniform standard for the appearance and fusion of the epiphyseal centres. The present study is an effort to estimate age among males and females by studying X-ray of distal end of radius and ulna. The age at which complete fusion was seen at distal end of radius and ulna among males and females is noted with help of data obtained in the present series.
Materials& Methods: A hospital based prospective study done on 200 cases (100 males and 100 females) in the age group of 15 to 21 years at orthopedic surgery department and Radiology department at GMC Baramullah, Kashmir, India during period between December 2020 to January 2022. They were selected by random sampling and confirming the age by birth certificate, ration card, passport or matriculation certificate whosoever came for x-ray. The Chronological Age of each subject was calculated using information on the certificate received for proof of Birth date. The purpose was explained to the subjects and written informed consent was obtained for the x-ray. X-ray of wrist joint showing lower end of Radius and Ulna in AP position were taken in all subjects.
Results: Among males & females no fusion was seen at distal end of radius & ulna before the age group of 17-18 years & 16-17 years respectively. 100% of males showed Degree 3 (complete fusion) at the distal end of radius & ulna after the age group of 18-19 years. 100% of females showed Degree 3 (complete fusion) at the distal end of radius after the age group of 17-18 years & distal end of ulna after the age group of 18-19 years.

Aim: To assess and compare age estimation by Drusini’s method and Jeon’s method and correlate chronological age and age estimation by both the methods in Indian Adults.
Methodology: Two hundred intraoral periapical radiovisuographs of the patients aged 20–69 years with optimum diagnostic quality radiographic images of permanent mandibular first molars were selected from the digital archive of the Department of Oral Medicine Diagnosis and Radiology from the dental college. Measurements were done using Drusini’s and Jeon’s methods and compared with the chronological age. A P < 0.05 was considered statistically significant. Analysis of variance followed by Tukey’s Post hoc test, t‑test.
Results; Mean chronological age, estimated using Jeon’s method and estimated by Drusini’s method, was 30.77 ± 9.32, 29.790 ± 7.729 and 27.885 ± 8.190, respectively. This difference was statistically highly significant, whereas Jeon’s method showed a strong positive correlation between chronological age and age.
Conclusion: The study concludes that Jeon’s method is more accurate than Drusini’s in the Indian population.

Introduction: Age estimation is one of the major parameters in the estimation of skeletal remains in forensic anthropology caseworkseries.The present investigation is an attempt to study the fusion of manubrium and xiphoid process with mesosternum in 70 sterna (49 males and 21 females) of known age obtained during autopsy.The current study has been conducted to estimate the age of an individuals based on the fusion and non-fusion of the sternum.
Materials and Methods: After obtaining prior permission from the institutional ethical committee, the study sample included those in the age range between 10 – 80 years that might include both the gender. This study included 70 sternums from the cadavers that include 49 males and 21 females.
Results: Age group of 21 – 30 reported to have greater study samples followed by 0 – 20 and 31 – 40. Greater number of fusions is seemed to be reported in Group – II (21 – 30 years).
Conclusion: To conclude, as the age progresses, the proportion of male and female cases, showing fusion at mesosternoxiphisternal and manubrio-mesosternal junctions increases. Manubrio-mesosternal junction was seemed to be very variable with regard to its fusion status as the joint remained unfused even in some of the elderly ages. Fusion is completed at the age of 40 years in male and 45 years in female

Cementum is a surface layer which is seen below the radicular dentin. It is near to the neck region of the tooth and thick at the root apex. It is formed by the cells known as cementoblast. Cementum helps the tooth to be attached to the periodontal ligament and alveolar bone through the sharpey’s fibre. Cementum helps in the repair and regeneration of damaged teeth. It has a high anti-absorption capacity. Age estimation using cementum technique is reliable to the teeth which is not affected by periodontal disease. Combined method of biological age estimation had high correlation when compared to public symphysis morphology and similar error were found among both the methodsThe literature search on age estimation using cementum as carried out for papers published from google scholar and pubmed with the intention of retrieving all original reports that were relevant to it. This review helps to provide deeper understanding about age estimation using cementum which benefits the dentist and forensic department.
