Abstract

Background and aims. Pathological fractures are rare in the maxillofacial region and account for less than 2% of all fractures in this site. They are defined as fractures that take place when bone has been weakened by an underlying pathologic process. Among all pathoses, cysts (although so common in the maxillofacial region) constitute a very small part. Here we report a case of a dentigerous cyst in a 38-year-old man.The cyst was associated with a mandibular second premolar tooth and resulted in a pathologic fracture. Excision of the lesion was performed and bony union was observed after 6 months. In the literature review, only one case of dentigerous cyst causing pathologic fracture was found. In addition to the report of the present case, pathologic fractures associated with all types of odontogenic cysts (totally just 12 cases) are reviewed in this article to provide a comprehensive and detailed collection.

Highlights

Pathologic fracture is usually defined as a type of fracture which is caused by an underlying pathologic lesion
In addition to the report of the present case, pathologic fractures associated with all types of odontogenic cysts are reviewed in this article to provide a comprehensive and detailed collection
Pathologic fractures of the maxillofacial region most frequently result from osteoradionecrosis and it is very interesting that cysts, which are so common in this area, rarely cause fractures

Summary

Introduction

Pathologic fracture is usually defined as a type of fracture which is caused by an underlying pathologic lesion. Dentigerous cysts most frequently involve mandibular third molars and are generally seen in patients between 10 and 30 years of age.. The cyst was associated with an unerupted mandibular second premolar tooth and resulted in pathologic bone fracture. A 38-year-old man presented with an asymptomatic mandibular mass He had been slightly punched in his face 2 days before visiting the Department of Oral Surgery, Faculty of Dentistry, Tabriz University of Medical Sciences. The radiolucency extended from the first premolar region to the second molar area It seemed to have destroyed bone almost from the edentulous alveolar crest to the inferior border of the mandible. The relatively large size of the lesion had pushed the lower left second premolar to the inferior border of the mandible (Figure 1). Bony union was radiographically observed after 6 months (Figure 3), and the patient remained symptom-free over a postoperative period of 2 years
