The Assessment of the Prevalence of Impacted Third Molars, Its Relation to Space Available for Eruption, and Its Effect on the Adjacent Second Molar in Adults From 18 to 65 Years of Age Using Orthopantomograms: A Retrospective Cross-Sectional Study.

Introduction Third molar impaction surgeries are part of the most common minor oral surgeries performed by maxillofacial surgeons. In spite of being part of the everyday evaluation, the importance of preoperative planning and intraoperative and postoperative complications cannot be overlooked. This study aims to evaluate the prevalence, patterns, available eruption space, and impact of third molar impaction on the adjacent second molar in an adult population.
