Background: The average stage of attrition in permanent first and second molars is an established method of age estimation in the adult population. The study was conducted with an objective of age estimation from the average stage of attrition of permanent molars.Methods: A total of 451 individuals of age more than 20 years were examined. Nepalese individuals with intact first and second permanent molars in the maxillary and mandibular arch on either side were included. The average stage of attrition of the maxillary first and second permanent molars on either side was calculated and subjected to regression analysis to derive equations.Results: Among a total of 451 participants, 231 (51.22%) were females and 220 (48.78%) males, with a mean age of 44.3 ± 13.9 years. There was a strong correlation between age and average stage of attrition of molars. The correlation was stronger for upper molars compared to the lowers. Additionally, the mean of the difference between real age and estimated age was lower for maxillary compared to mandibular molars. Compared to age estimation by univariable regression, multivariable regression had greater accuracy. Similarly, estimation of age from maxillary molars was more accurate as compared to mandibular (difference in years: 3.82 ± 3.03 for maxillary molars and 5.17 ± 4.2 for mandibular molars).Conclusions: Maxillary teeth are better for age estimation and using both maxillary first and second permanent molars gives better accuracy.Keywords: Age estimation by teeth; age reporting; forensic anthropology; forensic dentistry; tooth attrition

Objectives: To compare Demirjian Dental scoring method with Greulich-Pyle (GP) Skeletal method of age estimation in pubertal children. Materials and Methods: Sample of the study included 267 male healthy subjects of 11-16 years of age group.. Demirjian Scoring system was utilized to evaluate the orthopantomograms to assess their Dental age and the Hand-Wrist radiographs were analyzed to calculate the skeletal age by utilizing GP atlas. Chronological age was obtained from the date of birth of the subject .Both methods were compared with one another and with the chronological age. It was a cross-sectional study and only healthy male subjects without any clinical abnormalities were included in the study. Results: A total of 267 male subjects of 11-16 years of age group were assessed by Demirjian and Greulich Pyle Methods. Both were compared with Chronological Age. Data obtained was statistically analyzed and the Student “t” test was applied in the study population. The mean difference between Chronolgical age and dental age was 0.69years and that of chronological age and skeletal age was 0.87 years. It was observed from dental age assessment that it does not differ much from the skeletal age. Conclusion: It was concluded that Demirjian method of Age Estimation is more precise than Greulich Pyle method of Age Estimation. Furthermore both methods can be used selectively in Medicolegal cases to access bone age which can be easily correlated to chronological age.

Age changes cause major variations in the appearance of human faces. Due to many lifestyle factors, it is difficult to precisely predict how individuals may look with advancing years or how they looked with "retreating" years. This paper is a review of age variation methods and techniques, which is useful to capture wanted fugitives, finding missing children, updating employee databases, enhance powerful visual effect in film, television, gaming field. Currently there are many different methods available for age variation. Each has their own advantages and purpose. Because of its real life applications, researchers have shown great interest in automatic facial age estimation. In this paper, different age variation methods with their prospects are reviewed. This paper highlights latest methodologies and feature extraction methods used by researchers to estimate age. Different types of classifiers used in this domain have also been discussed.

Background: Molars and premolars are considered as the most vulnerable teeth of caries attack, which is related to the morphology of their occlusal surfaces along with the difficulty of plaque removal. different methods were used for early caries detection that provide sensitive, accurate preoperative diagnosis of caries depths to establish adequate preventive measures and avoid premature tooth treatment by restoration. The aim of the present study was to evaluate the clinical sensitivity and specificity rates of DIAGNOdent and visual inspection as opposed to the ICDAS for the detection of initial occlusal caries in noncavitated first permanent molars. Materials and Methods: This study examined 139 occlusal surface of the first permanent molar pooled from fifty patients aged 8-9 years by three methods. The selected criteria include one occlusal site per tooth (first permanent molars) with carious lesions range from 0 to 3 according to ICDASII (gold standard) visual criteria then the clinical sensitivity and specificity of visual inspection according to Ekstrand et al.in 1997 and DIAGNOdent were performed. . Results: the highest correlation was found between the ICDASII and DIAGNOdent. The sensitivity of the DIAGNOdent for the enamel caries detection (D1) was better than that of visual inspection. The sensitivity and the specificity for the DIAGNOdent at D3 threshold were better than the D1 threshold and the visual inspection method. Conclusion: DIAGNOden pen can be used as a tool for early caries detection in cases of difficult diagnosis that provide good additional sensitivity to the visual inspection.

Relevance. Prevention of caries of the first permanent molars is one of the most relevant problems in pediatricdentistry.Purpose – to develop an algorithm for prevention of first permanent molars caries in children with differentlevels of caries risk.Materials and methods. The article presents the results of the implementation of the algorithm for prevention of first permanent molars caries in children with different levels of caries risk. This algorithm includes a comprehensive assessment of the values of indices dmft, DMFT, OHI-S, and the patient's health group is also taken into account. The study involved 253 children aged 6-7 years divided into 4 groups: 3 groups of children depending on the health group and the control group. 3 subgroups were identified in each group – with a low, medium, and high caries risk. We developed preventive measures schemes were for children of each group including training in oral hygiene; controlled and home toothbrushing using fluoride-containing toothpastes; applications of varnishes containing fluoride, calcium, phosphates from 2 to 3 times a year; fissure sealing of the first permanent molars. We carried out these activities were for 24 months, and then evaluated theirs effectiveness. Children in the control group were trained in oral hygiene. The clinical effectiveness of medical prophylaxis was evaluated by changes in the above clinical indicators.Results. In group of children with medium caries risk the increase in caries was 0.09, and the reduction in caries was 89.65%. In children with a low and high caries risk no increase in caries was observed; the reduction in the intensity of caries was 100%. A significant decrease in OHI-S oral hygiene index values was noted in all groups (p < 0.05). We noted high preventive efficacy of fissures sealing in the first permanent molars. No occlusal surface caries developed in sealed fissures.Conclusions. The application of the proposed preventive schemes in patients demonstrates high efficacy of fluoride and calcium-containing varnishes and sealing the fissures of the first permanent molars.
