Panoramic Radiography in Evaluating the Pattern of Impacted Third Molars
Journal Title: Saudi Journal of Oral and Dental Research - Year 2018, Vol 3, Issue 2
Abstract
Abstract:The aim of this study was to determine the prevalence of impacted third molars in terms of frequency, angulation, level of eruption and available retromolar space. In this retrospective study, a total of 402 OPGs were finalized. Pattern of impacted third molars was evaluated using WINTERS classification for the angulation and PELL & GREGORY classification for the level of eruption and available retromolar space.Among all the OPGs reviewed, third molar impaction was more prevalent in mandible than in maxilla. The most common angular position was mesioangular in mandible and vertical in maxilla. The most common level of eruption was Position B i.e. the highest position of impacted third molar was located below the occlusal plane but above the cervical line of adjacent second molar. Majority of third molars were impacted at less than adequate space.The current study revealed that the most frequent pattern of impaction according to PELL & GREGORY classification was Class 2B followed by Class 1C. Keywords:Angulation, Impaction, Mandibular third molar, Radiographic evaluation.
