Abstract

Objectives: This study was conducted to establish if any correlation exists between individual’s chronological age and lambdoid sutures closure status in mortals through modified reverse panoramic radiograph.Materials and Methods: Total number of 140 subjects, 10 years and beyond were included in the study, and divided into seven groups with an age interval of 5 years. Assessment of lambdoid suture closure was done according to Frederic Rating Scale on modified reverse panoramic radiographs. Data obtained was subjected to statistical analysis using Cramer’s V test.Results: A significant correlation was observed between the age group and suture closure. Cramer’s test gave value of 0.000, and was interpreted as a good correlation between the age and suture closure status with a P value of <0.05Conclusion: Lambdoid suture can be very effective and reliable practical tool for age assessment in mortalsthrough modified reverse panoramic radiography (ectocranially)

Abstract

Objectives: This study was conducted to assess the reliability of age estimation using the radiographic visibility of periodontal ligament surrounding the roots of completely erupted mandibular 3rd molar.Materials and methods:Visibility ofperiodontal ligament was assessed in completely erupted mandibular third molars, in a sample of 135 panoramic radiographs, of which 55 belonging to females and 80 to males, from a Mysore population aged 18to 32 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, mean, standard deviation, minimal & 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 1 can be used for predictability of age above 19 years and stage 3 for predictability of age above 23 years. No significant correlation exists between periodontal ligament visibility and gender of the individual.Conclusion:Thistechnique is advocated for determining age above 19 years as it is a relatively simple and reliable method. Differences exist in different ethnicities demanding specific population standards.

Abstract

Background: Morphometric analysis of teeth on radiographs for age estimation are considered to be simple, reliable and non-invasive. The aim of this study was to analyse the efficacy of tooth coronal index (TCI) to estimate age in Indian population and to assess the influence of diet and masticatory habit on TCI. The study comprised of 160 subjects in the age range of 21-71 years, categorized into groups based on chronological age, gender, diet and masticatory habit. Coronal Height (CH) and Coronal Pulp Cavity Height (CPCH) of permanent mandibular first molars was measured on digital panoramic radiographs using Planmeca Romexis software measurement tools. TCI was calculated using the formula: TCI= (CPCH ×100)/CH. Statistical analysis was performed, ANOVA and Pearson correlation was applied along with regression analysis to obtain an estimated age using TCI. Results: A negative correlation was obtained between the chronological age and TCI. Three-way ANOVA exhibited a significant difference in TCI within the age groups and dietary groups (p value = <0.05). There was no significant difference within the sexes, sides and masticatory groups. The most precise estimated age using the regression formula was in individuals between 31 – 40 years with an error of +/- 5 years in 55% of females, 65% of males. Conclusions: This study suggests that although TCI is a good predictor of age, it is most suitable to determine age of individuals between 31-40 years with the least error in estimation. This study also throws a light on the influence of diet on TCI.
