Abstract

Background and Aim: Dental age estimation (DAE) is one of the vital aspects in forensic dentistry. After tooth eruption, the size of the pulp cavity decreases constantly with age owing to deposition of secondary dentine. Various methods have been devised for estimating age, but the radiographical methods have the advantage of being non- invasive, easy, and fast. Previous studies have correlated age by using pulpal length (L) to width (W) ratio of different single rooted teeth of different population subset. Yet, a dearth exists in studies on North Indian population subset. Hence, the aim of this study was to investigate the relationship between the chronological age and the ratio of pulpal L/W of maxillary lateral incisor using digital panoramic radiographs (DPRs) of North Indian population.

Material and Methods: DPRs of subjects aged 18- 60 years were collected from the archives of the database of patients who visited a private Imaging Centre in North- India based on the set inclusion and exclusion criteria. These DPRs were evaluated for 134 maxillary lateral incisors on either side (Right and Left). The pulpal L/W ratio of each tooth was measured by an Oral Radiologist using the ImageJ, open-source software and were statistically analysed.

Results: The Pearson correlation coefficient (r) was 0.939 indicating a statistically significant correlation between the pulpal L/W ratio of the maxillary lateral incisor with chronological age (P = 0.000*).

Conclusion: The ratio of pulpal L/W of maxillary lateral incisor is of paramount importance and can be used as a predictor of age in North- Indian population using modified Kvaal’s method.
