摘要： 目的:调查研究牙齿功能面磨耗与偏侧咀嚼及侧方咬合的关系。方法:通过问卷调查和临床检查收集数据,t检验分析牙齿功能面磨耗与偏侧咀嚼习惯、侧方咬合之间的关系。结果:在257名受试者中,有133名(52%)受试者有偏侧咀嚼习惯,其中77名(30%)为右侧咀嚼习惯,56名(22%)为左侧咀嚼习惯。偏侧咀嚼习惯与牙齿功能面磨耗相关(P<0.05),进一步分区研究显示主要是习惯侧的磨合面磨耗严重(P=0.038<0.05)。所有的受试者中,在左侧,23名(8.9%)受试者为尖牙保护牙合,213名(82.9%)受试者为组牙功能牙合,21名(8.2%)受试者无法测量;在右侧,22名(8.6%)受试者为尖牙保护牙合,217名(84.4%)受试者为组牙功能牙合,18名(7.0%)受试者无法测量。组牙功能牙合磨牙区牙齿牙合面磨耗要比尖牙保护牙合磨牙区牙齿牙合面磨耗严重(P<0.05)。结论:在偏侧咀嚼侧的牙齿功能面磨耗更严重;组牙功能合磨牙区牙齿牙合面磨耗要比尖牙保护牙合磨牙区牙齿牙合面磨耗严重。

Abstract: Objective:To investigate the relationship between tooth wear and chewing side preference as well as lateral occlusion. Methods: The data were collected by a questionnaire survey and clinical examination. Then t-test was applied to analyze the relationship between occlusal tooth wear and chewing side and preference as well as lateral occlusion. Results: There were 133 subjects (52%) who reported a chewing side preference: 77 (30%) for the right side and 56 (22%) for the left in all of 257 subjects. Chewing side preference was significantly correlated with OTWI scores (P<0.05). If analyzed for the different dental regions separately, the significant difference of OTWI score only existed in the molar region (P<0.05). Of all subjects, 23 (8.9%) had canine protected guidance, 213 (82.9%) had group function, 21 (8.6%) were not measurable at the left side. And 22 (8.6%) subjects had canine protected guidance, 217 (84.4%) had group function, 18 (7.0%) were not measurable at the right side. Subjects with group function had higher mean OTWI scores than those with canine protected guidance in the molar region (P<0.05). Conclusion:Occlusal tooth wear of the chewing side preference was severer than the other side. The molar region occlusal tooth wear of group function was severer than that of canine protected guidance in the molar region.
