Morphometric Changes in a Sample of Various Age Groups of the Thai Population: A Panoramic Radiographic Study

Objective The current investigation was conducted to examine the alterations in oral conditions and panoramic image parameters that occur with age. Methods The study sample consisted of 300 male participants and 300 female participants, ranging in age from 10 to 69 years. The age-related changes in intraoral circumstances and morphometric parameters, as observed in panoramic photographs, were explored. A two-way parametric analysis of variance was used to examine the effects of age group and sex. The frequencies and percentages were calculated and compared among groups using the chi-squared test for category variables. A p-value below 0.05 was considered to be statistically significant. Results The prevalence of intraoral conditions showed a positive correlation with advancing age. Males exhibited significantly higher crown, root, and tooth lengths in both the upper and lower canines. There was a significant difference between males and females in terms of the pulp area, the pulp-tooth ratio of the upper first molars, and the pulp area of the lower first molars ( p < 0.05). The study found a substantial correlation between the radiomorphometric parameters and age, with similar trends observed in both males and females. Conclusion The findings of our research have the potential to contribute to the evaluation of an individual's age category and offer insights into the patterns of several observable factors on panoramic radiographs.
