Estimación de edad dental por desarrollo del tercer molar mediante RX panorámicas, Instituto IDEMPI, Milagro. Octubre 2015 - julio 2016.

Abstract

Introduction: There are several scientific methods to estimate the dental age. The Dermijian method has been used since it is the most accurate and reliable to demonstrateprobabilities in ages. The present study is to establish the relationship between the estimation of the dental age in the development of the third molar and the chronological age, according to the stages of Dermijian in panoramic radiographs. Materials and methods: A descriptive study of transversal and correlational type was carried out. 500 panoramic radiographs of both sexes were studied, with ages between 12-21 years of age, who attended the Idempi Institute in the Canton Milagro, in the months of October 2016 to July of the 2017. The dental ages were calculated by the method of Dermijian, the dental ages by the third molar using the stages of maturation of Dermijian and using the correlation of Pearson and Values P. Results:In part 18, the stage D presented an average age of 15.06 ± 1.78 for female sex and 14.08 ± 1.95 years for male sex. The third molar that most sets the dental age using the Dermijian method is part 18 with 12,75%.If differences were found instages D, E, F, G and H. If the difference was found in part 18 and 48 in its root formation of the third molar piece. In stage H 88.57% of female sex and 92.31% male sex were 18 or more years old. Conclusions:The method of Dermijian is one of the most accurate and probabilistic to estimate the dental age since it facilitates the study and helps us to see the maturation of the third molar in the process of its development.
