The aim of our study was to investigate the influence of the occlusal support, and mandibular third molars on mandibular angle and condylar fractures.
Patients with unilateral and isolated angle or condylar fractures were included in this retrospective, cross-sectional study. Data was collected from patient records and panoramic x-rays. The predictor variables included the type of occlusal support and the presence or absence of third molars. The outcome variable was angle or condylar fracture, while other predictor variables included demographic factors. Bivariate (χ2 test) and logistic regression analyses were conducted to investigate the associations between variables and the outcome. 43 angle (mean age: 29.9 ± 12.8 years; 98.4% male) and 37 condylar (mean age: 46.8 ± 20.2 years; 62.2% male) fracture cases were included in this study. Bilateral occlusal support was present in 81.4% of angle fracture group and in 51.3% of condylar fracture group (p<0.001). In the case of bilateral occlusal support, an odds ratio (OR) of 4.2 was found for angle fractures (p<0.006). A third molar was present in 86% of the angle fracture group and in 43.2% of the condylar fracture group (p<0.001). The presence of a third molar exhibited an odds ratio of 8.1 for the angle fractures (p<0.001). When bilateral occlusal support and third molar were present simultaneously, the risk was 15.9 times higher for an angle fracture (p<0.001).
The presence of occlusal support and/or third molars was significantly associated with angle fractures, however, the absence of occlusal support and/or third molars significantly correlated with condylar fractures. Orv Hetil. 2020; 161(28): 1166-1174.
本研究旨在探讨咬合支持及下颌第三磨牙对下颌角和髁突骨折的影响。
本回顾性横断面研究纳入了单侧孤立性下颌角或髁突骨折患者。数据收集自患者病历和全景X线片。预测变量包括咬合支持类型及第三磨牙的有无。结果变量为下颌角或髁突骨折，其他预测变量包括人口统计学因素。采用双变量（χ2检验）和逻辑回归分析来研究变量与结果之间的关联。本研究纳入了43例下颌角骨折病例（平均年龄：29.9±12.8岁；98.4%为男性）和37例髁突骨折病例（平均年龄：46.8±20.2岁；62.2%为男性）。下颌角骨折组81.4%存在双侧咬合支持，髁突骨折组51.3%存在双侧咬合支持（p<0.001）。在双侧咬合支持的情况下，下颌角骨折的优势比（OR）为4.2（p<0.006）。下颌角骨折组86%存在第三磨牙，髁突骨折组43.2%存在第三磨牙（p<0.001）。第三磨牙的存在使下颌角骨折的优势比为8.1（p<0.001）。当同时存在双侧咬合支持和第三磨牙时，下颌角骨折的风险高15.9倍（p<0.001）。
咬合支持和/或第三磨牙的存在与下颌角骨折显著相关，然而，咬合支持和/或第三磨牙的缺失与髁突骨折显著相关。《匈牙利医学周报》。2020年；161(28): 1166 - 1174。
