The relationship between the status and position of third molars and the presence of mandibular angle and condylar fractures.
INTRODUCTION
The aim of this study was to assess the relationship between the status and position of third molars, and the presence of mandibular angle and/or condylar fractures, in a group of patients treated for mandibular fractures, thus hoping to contribute to the knowledge of potential predictors of these fractures.


METHODS
A retrospective study was designated to include all the patients who were diagnosed and treated with open reduction and internal fixation for isolated mandibular angle fractures or isolated mandibular condylar fractures between 1st of January 2012 and 31st of December 2018. The following data were collected for each included patient: gender, age, etiology, site and side of the fracture, and presence and eruption state of third molars in the fracture side.


RESULTS
Seventy patients were diagnosed with a condylar fracture, 48 with an angle fracture. No statistically significant difference was observed as for etiology and gender distribution between angle fracture and condyle fracture patients (p > 0.05). Angle fractures were statistically associated with the presence of third molars, whereas condylar fractures with the absence of third molars (p < 0.000005). The presence of completely erupted 3Ms was associated with condylar fractures (p < 0.05), and partially impacted 3Ms were associated with angle fractures (p < 0.0005).


CONCLUSIONS
Mandibular angle fractures and third molar presence are associated in patients who present with mandibular fractures, especially if the third molar is incompletely erupted. This information should be kept in consideration as for the diagnosis and management of patients with mandibular fractures.
