There have been passing references in history that excessive occlusal forces might be a causative factor in gingival recession. The purpose of the present cross-sectional study was to explore the role of trauma from occlusion on the development of gingival recession.
Three hundred patients reporting to the department of Periodontics were screened for the presence of gingival recession in the lower incisors. A single trained examiner carried out clinical examination for signs of trauma from occlusion, such as fremitus test, presence of wear facets and mobility. The data were analyzed by chi square test.
No statistically significant relationship was observed between the presence of a positive fremitus and wear facets with gingival recession. However, a significant association was observed between patients who experienced mobility and gingival recession.
There does appear to be a relationship between fremitus and tooth wear with gingival recession based on the results of the present study, though not conclusive. However, the sign of tooth mobility, which is a feature of trauma from occlusion, appeared to be a predictor of positive association with gingival recession.
历史上曾有文献提及,过大的咬合力量可能是牙龈退缩的一个致病因素。本横断面研究的目的是探讨咬合创伤在牙龈退缩发展过程中的作用。
对到牙周科就诊的300例患者进行检查,以确定其下切牙是否存在牙龈退缩。由一名经过培训的检查者进行临床检查,以查找咬合创伤的体征,如牙震荡试验、磨耗面的存在情况和牙齿松动度。数据采用卡方检验进行分析。
牙震荡试验阳性和存在磨耗面与牙龈退缩之间未观察到具有统计学意义的关系。然而,观察到牙齿松动的患者与牙龈退缩之间存在显著关联。
根据本研究结果,牙震荡和牙齿磨损与牙龈退缩之间似乎存在某种关系,尽管尚无定论。然而,牙齿松动这一咬合创伤的特征,似乎是与牙龈退缩呈正相关的一个预测指标。
