Above or below 14 years? An orthopantomographic study based on chronological course of eruption of mandibular premolars and second molars in a sample of south Indian children

Prior Probabilities and the Age Threshold Problem: First and Second Molar Development

“…Lucas et al (2014) also introduced a two-by-two tabling method similar to that seen in more recent studies that use dental development to assess MACR. The four more recent studies (Balla et al 2019;Cameriere et al 2018;Ravi et al 2020;Thomas et al 2021) all used some form of two-by-two tabling of actual age at or above versus below a threshold against the number of individuals that fall above or below some cut-point for an age indicator. This two-by-two tabling approach suffers from three problems.…”

“…One consequence of the imperfect relationship between estimated and actual age is that the has the legal age of majority. Despite considerable discussion about using third molar development to assess whether an individual has reached the legal age of majority (Acharya 2011;Akkaya et al 2019;Cameriere et al 2008;Corradi et al 2013;De Luca et al 2014;Galić et al 2015;Liversidge and Marsden 2010;Lucas et al 2016;Márquez-Ruiz et al 2017;Sironi et al 2018;Streckbein et al 2014;Uys et al 2018), comparatively little work has been done on dental development as a marker for whether or not an individual has reached MACR (Balla et al 2019;Cameriere et al 2018;Lucas et al 2014;Ravi et al 2020;Thomas et al 2021;Yadava et al 2011).…”
