Abstract
Third molar development is a concern in dental care because of its influence on stomatognathic system. Due to third molar irregular pattern of eruption, different clinical and radiographic considerations on how to decide an extraction were studied. This study was aimed to evaluate the effect of mandibular third molar mesial angulation (MA) towards the extractions on panoramic radiographs. This was a retrospective study. A longitudinal study of mandibular third molars (n=192) of 102 individuals (50 Female and 52 Male) was conducted. Development of the mandibular third molar was staged according to modified Köhler et al. staging technique. Mesial angulation was measured from the intersection between axes of third molar and adjacent second molar of the most developed stage for extraction cases or before root completion for nonextraction cases. Of 102 subjects, 107 mandibular third molars were extracted. The increase of 1° of MA would increase the odds ratio (OR) of extraction by 1.113 (95% CI 1.070-1.158, p<0.01). The ROC curve showed the MA of 18.5o as the threshold of extraction with 76% of sensitivity and 68% of specificity. In conclusion, MA has the possibility as a predictive factor of mandibular third molar extraction. Future studies using bigger sample sizes and variations of third molar development are suggested.
