The objective of this study was to estimate the prevalence of impacted teeth in a subpopulation of Brazilian patients based on the retrospective analysis of panoramic radiographs obtained at an oral radiology clinic. Out of 1,977 panoramic radiographs, 1,352 fulfilled inclusion criteria, and 22,984 teeth were assessed. Data were statistically analyzed using Kolmogorov-Smirnov's and Levene's tes...

Extraction of the lower third molar is one of the most common procedures performed in oral surgery. In general, impacted tooth extraction involves sectioning the tooth’s crown and roots. In order to divide the impacted tooth so that it can be extracted, high-speed air turbine drills are frequently used. However, complications related to air turbine drills may occur. In this report, we propose a...

INTRODUCTION The early orthodontic treatment allows correction of skeletal discrepancies by growth control, and the elimination of deleterious habits, which are risk factors for the development of malocclusions, favoring for the correction of tooth positioning later in a second treatment stage. During development of teeth and occlusion, the mandibular second molars commonly erupt in the oral ca...

INTRODUCTION The most commonly impacted tooth in the oral cavity is the mandibular third molar. Various etiologic factors have been suggested for impacted mandibular third molars. The pattern and prevalence of impacted mandibular third molars vary with different population and region. This study throws light on the prevalence and pattern of impacted mandibular third molars in Eritrea, East Afri...
