Age estimation from pulp/tooth area ratio (PTR) in an Indian sample: A preliminary comparison of three mandibular teeth used alone and in combination

Age estimation by pulp-to-tooth area ratio using cone-beam computed tomography: A preliminary analysis

“…[68] However, the present study has a comparable r value to previous studies undertaken on Indian populations,[92021] which underscores the potential limitation of radiographic assessment of secondary dentinal formation in this country. It has been suggested that modest correlations may be inherent in Indians, precluding optimal age estimation,[22] and the findings of the present study reinforce the same.…”

Dental Age Estimation in Adults: A Review of the Commonly Used Radiological Methods

“…In total, 20 articles [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] were included and several methods were presented in literature (Table 1). In general the methods were classified into three categories, Kvaal's, Ikeda's, and…”

“…Among the 20 articles, 13 studies [5][6][7][8][9][12][13][14][15][16][17]22,23) were performed on orthopantomograms for measuring of the size of the pulp cavity and 7 studies 4,10,11,[18][19][20][21] were performed on periapical radiographs. Although most studies included range of age, only one study 23) provided insufficient data of age.…”

“…All studies executed a reproducibility test in order to evaluate the accuracy of the measurements except for one study. Eight studies 5,8,9,12,13,19,20,23) carried out measurement of the pulp and tooth size by one observer while 12 studies 4,6,7,10,11,[14][15][16][17][18]21,22) carried out by two observers and reexamined to test intraobserver or interobserver reproducibility of the measurements.…”

An Age Estimation Method to Panoramic Radiographs from Indonesian Individuals

“…Examples of the application are AutoCAD2000 [4], Adobe Photoshop [5], etc. However, those applications still need expert decisions such as how to determine pulp area or tooth boundary.…”
