Age estimation in Western Indian population by Cameriere's and Drusini's methods

Abstract

Objectives: The aim of the present study is to determine applicability of Cameriere's and Drusini's methods in Western Indian population. Methodology: Panoramic radiographs of total 300 Gujarati individuals, equally divided into four study groups were studied by two investigators. The pulp/tooth area ratio (AR) were calculated for maxillary and mandibular canines and tooth coronal indexes (TCI) i.e., the ratio between coronal pulp cavity height and crown height were calculated for mandibular premolars and first and second molars. The acquired data were subjected to correlation and regression analysis and also inter and intraobserver reliability was obtained for both the investigators. Results: The ARs and TCIs for all the respective teeth were significantly correlated with the age of the individuals. The individual regression formulae were derived for all the teeth and were then used separately to calculate the age. There was no statistically significant difference between the mean chronological age and mean calculated age for all the teeth.(P > 0.05). The mean absolute errors for all the teeth were <10 years. Conclusion: The findings of this study prove the applicability of Cameriere's and Drusini's age estimation methods for Western Indian population. However, the weak correlation coefficients suggest the need for further studies to get more accurate results.

Age Estimation in Brazilian Adults Using the Pulp/Tooth Ratio of the Maxillary Canine and Mandibular Second Premolar

“…Previous studies employing the pulp/tooth ratio strategy typically selected singlerooted teeth, as they undergo fewer morphological changes over time. Among the dental groups investigated, maxillary canines and mandibular premolars were the most used [2,5,7,[10][11][12][13][14][15]. It is noteworthy that Cameriere's methodology [5] recommends using a minimum of 20 points for outlining the tooth and 10 points for outlining the pulp.…”

“…This approach is warranted due to specific geometric variations inherent in panoramic and periapical radiographs [8,9,18]. Previous studies have often applied the same formula to both panoramic and periapical radiographs [15,19].…”

“…Similar challenges were encountered in the present study. Research in this field suggests incorporating formulas derived from diverse populations or augmenting the sample size [7,10,15,[21][22][23][24].…”

“…Global migration and the settlement of refugees worldwide have increased the need for physicians and forensic dentists to determine the chronological age of individuals using biological age estimation techniques [9,10]. Radiographic examinations, being readily available, non-invasive, and reproducible, are extensively used for this purpose [1,4,6,[10][11][12][13][14][15][16][17][18].…”

Digital Panoramic Radiographs for Age Prediction Utilizing the Tooth Coronal Index of First Mandibular Bicuspids Among the South Indian Population

“…Among these, the Teeth Coronal Index (TCI) stands as a method employed in forensic odontology to estimate age. This technique involves the examination of secondary dentin deposition on the roof of the pulpal chamber within a tooth [ 1 ].…”
