目的探究个别正常[牙合]与错[牙合]畸形患者全口牙齿磨损情况的差异,分析不同错[牙合]畸形的牙齿磨损发病规律,为牙齿磨损的防治工作和病因研究提供参考。方法选择2019年2月-2022年5月就诊于我院的个别正常[牙合]59例和错[牙合]畸形患者189例为研究对象,分为个别正常[牙合]组和错[牙合]畸形组。错[牙合]畸形组包括安氏Ⅰ类61例,Ⅱ^(1)类66例、Ⅲ类62例。检查每颗牙齿的切缘及[牙合]面的磨损情况,并采用Smith牙齿磨损指数TWI(Tooth Wear Index)分度方法逐一记录,统计分析各组之间的磨损差异。结果错[牙合]畸形组的磨损程度较正常[牙合]组严重(t=27.758,P<0.001);前牙:安氏各类错[牙合]畸形的前牙磨损均较个别正常[牙合]组严重,且安氏Ⅲ类磨损较Ⅰ、Ⅱ^(1)类严重(P<0.001),安氏Ⅰ类磨损重于安氏Ⅱ^(1)类(P<0.001)。前磨牙:个别正常[牙合]的前磨牙磨损程度均较各类错[牙合]畸形轻,安氏Ⅱ^(1)类的磨损较安氏Ⅰ、Ⅲ类更严重(P<0.001),安氏Ⅲ类的磨损重于安氏Ⅰ(P<0.001)。磨牙:安氏各类错[牙合]畸形组的磨牙磨损均高于个别正常[牙合],安氏Ⅰ类的磨损程度低于安氏Ⅱ^(1)、Ⅲ类(P<0.001),而安氏Ⅱ^(1)类和Ⅲ类错[牙合]畸形的磨牙磨损差异无统计学意义(P=0.282)。结论错[牙合]畸形是牙齿磨损发病的危险因素之一,安氏Ⅲ类前牙、安氏1类前磨牙磨损较严重,安氏Ⅱ^(1)、Ⅲ类错[牙合]畸形磨牙磨损程度均较Ⅰ类严重,应引起更多的重视。
Objective To explore the difference between individual normal and malocclusion patients in terms of whole-mouth tooth wear,analyze the pathogenesis of tooth wear in different malocclusions,so as to provide reference for the prevention and treatment of tooth wear and etiological research.Methods A total of 59 cases of individual normal occlusion and 189 cases of malocclusion who treated in our hospital from February 2019 to May 2022 as the study subjects,which were divided into individual normal occlusion group and malocclusion group.The malocclusion group included 61 cases of Angle Class Ⅰ,66 cases of Class Ⅱ^(1) and 62 cases of Class Ⅲ.The Wear of incisal edge and occlusal surface of each Tooth was examined,and the Smith Tooth Wear Index(TWI)indexing method was used to record one by one,and the wear differences among all groups were statistically analyzed.Results The anterior teeth wear of all kinds of malocclusion were more serious than that of individual normal occlusion group,and the wear of classⅢwas more serious than that of classⅠand Class Ⅱ^(1)(P<0.001),and the wear of classⅠwas more serious than that of class Ⅱ^(1)(P<0.001).Premolar:The wear of individual normal occlusion anterior molars were all lighter than all types of malocclusion,the wear of Angle ClassⅡ^(1) was more severe than Angle Class Ⅰ and Ⅲ(P<0.001),and the wear of Angle Class Ⅲ was more severe than Angle Class Ⅰ(P<0.001).Molar:Molar wear was higher in all the Angle types of malocclusion group than the individual normal occlusion,and the wear was lower in Angle Class Ⅰ than in Angle Class Ⅱ^(1) and Ⅲ(P<0.001),the difference of molar wear in Angle Class Ⅱ^(1) and Ⅲ malocclusion was not statistically significant(P=0.282).Conclusion Malocclusion is one of the risk factors for the onset of tooth wear,and the wear of Angle Class Ⅲ anterior teeth and Angle Class Ⅱ^(1) anterior molars is more severe,and the wear of both Angle Class Ⅱ^(1) and Ⅲ malocclusion molars is more severe than that of Class Ⅰ.People should give more weight to these.
