Unusual Impaction of a Mandibular Second Premolar: Case Report

Aim The aim of this study is to present clinical and radiographic features along the treatment of an unusual impacted mandibular second left premolar of a patient applied to our faculty. Case Report A 23-year-old female patient was referred to our clinic with pain and mild swelling that is localized at mandibular left area. We examined her panoramic radiography and we noticed that her mandibular second left premolar was impacted vertically and the point of root crossed the cortical bone at the inferior border of mandible. Then, we took a dental volumetric tomography from the patient for a more sensitive assessment of the localization of the impacted tooth and its relationship with the mandibular canal. The tooth was extracted at the Department of Oral Surgery to relieve the pain and the patient was followed up periodically. Discussion In the case of having an impacted tooth, periapical, orthopantomographs or occlusal radiographs are used to detect it. The images obtained with these conventional techniques are 2-dimensional and not sufficient for determining of the exact localization and the relation of the tooth with adjacent structures. Latest research shows that instead of conventional radiographies, Cone beam computed tomography is more successful in defining the localization of impacted teeth. Conclusion In the treatment of impacted teeth, orthodontic treatment or tooth extraction can be applied according to the age of the patient and the condition of the dental arch.
