Estimation of the age of senegalese children based on panoramic radiography of the third mandibular molar
Introduction : The objective of this preliminary study was to evaluate the interest of the third molar in the determination of the age of Senegalese subjects by the Demirjian method.
Materials and Methods: This is a descriptive cross-sectional study of digital panoramic x-rays of Senegalese patients, aged 5 to 24 years. The statistical analysis was performed with the SPSS software. The significance threshold was less than 0.05 (p<0.05).
Results: Of the patient radiographs explored, 283 met the selection criteria. The sample selected consisted of 52% (n=146) boys and 48% (n=137) girls. Germination of the third mandibular molar began at an average age of 7.21±1.64 years in boys and 7.71 ± 3.71 years in girls. Apical closure occurs at 20.11± 2.89 years and 20.70±2.73 years for boys and girls, respectively.
Conclusion: This preliminary study shows the interest of the use of the third molar in the estimation of age in the Senegalese population. A radiographic study of the third molar on the determination of the civil age, with a representative sample of African subjects aged between 14 and 22 years proves necessary.
