Abstract

Background: Age estimation plays an important role in both dentistry and forensics. Today, the London Atlas method is widely used by the students or researchers, but biological growth (head dimensions and body height) may also provide a guide about the developmental stage of humans. Purpose: To evaluate the correlation between head size with body height to match with dental age to determine the biological dan chronological age. Methods: Using cross sectional study to 51 samples with age from 4 until 20 years. Head length, head width, body height, and dental panoramic photo were recorded for each sample. Statistical analysis using Spearman correlation tests and linear regression to compare with many variables. Results: Positive correlation between body height and dental age (r = 0.892; p < 0.001). Head length (r = 0.475; p < 0.001) and head width (r = 0.477; p < 0.001) show moderate correlations with dental age. Next, the ratio of head length to body height shows a significant correlation with chronological age (p < 0.001; R² = 0.614), but the cephalic index shows no significant correlation with either dental age or chronological age. Conclusion: Head length and body height are significantly correlated with dental age (London Atlas method), so that it can be useful for age estimation. .

Abstract

Background: Age estimation is a crucial aspect of forensic dentistry, particularly in identifying children whose chronological age is uncertain or undocumented. The Demirjian method is one of the most widely used approaches to determine age by evaluating the mineralization stages of seven mandibular permanent teeth using panoramic radiographs. Body Mass Index (BMI) reflects nutritional status and general growth patterns, which may influence the rate of dental maturation. Purpose: This study aimed to analyze the correlation between BMI and dental age estimation based on the Demirjian method in children. Methods: This analytical observational study with a cross-sectional design involved 42 children who underwent panoramic radiographic. BMI values were calculated from measurements of body weight and height, while dental age was determined by assessing tooth development stages using the Demirjian method. Results: The results of the Spearman test showed that 90.4% of participants had consistent dental and chronological ages, 4.8% showed advanced, and 4.8% delayed dental maturation. Significant correlation was found between BMI and dental age (p= 0.038), while a not-significant correlation was observed between BMI and chronological age (p= 0.117). There was a significant correlation between dental age and chronological age (p= 0.000). The intraclass correlation coefficient (ICC= 0.997) indicated excellent inter-examiner reliability. Conclusion: These findings suggest that BMI variation is associated with differences in dental development, indicating its potential use as a complementary indicator in biological age estimation within forensic dentistry; however, this association should be interpreted cautiously, as potential confounding factors were not controlled in this study.Keywords: Body Mass Index, Dental Age, Demirjian Method, Panoramic Radiography, Children

Abstract

Introduction: Forensic odontology is a branch of dentistry that focuses on the resolution of forensic cases. This discipline encompasses identifying personal information, including age, race, and gender. One of the methods utilized is lip print analysis. Objective: To determine the consistency of Suzuki-Tsuchihashi and Renaud methods in determining dominant lip print patterns in males and females. Methods: This study employs a cross-sectional design with an observational approach, involving 100 respondents (50 males and 50 females) aged 18–25 years selected using quota sampling. Lip print patterns were classified using the Suzuki–Tsuchihashi and Renaud methods, and the data were analyzed to determine the consistency between Suzuki-Tsuchihashi and Renaud methods. Results: The Cohen’s Kappa analysis showed level of consistency in males is fair (κ = 0.230; p = 0.302) and moderate in females (κ = 0.422; p = 0.531). In both groups, p-values greater than 0.05 indicate no statistically significant difference between the Suzuki–Tsuchihashi and Renaud methods. Conclusion: There is no statistically significant difference between the Suzuki-Tsuchihashi and Renaud methods. However, both methods demonstrate a fair to moderate of level of consistency in classifying dominant lip print patterns in males and females. Keywords: Forensic Odontology, Gender Identification, Lip Print, Renaud Method, Suzuki-Tsuchihashi Method
