The effect of tooth occlusal surface wear on the inclination of the firstmandibular molar tooth long axis: An anatomic measurement study
Abstract：AIM: To investigate the characteristics and significan ce of the effect of tooth occlusal surface wear on the long axis of the mandibul ar first molar tooth. METHODS: Three groups of mandibular first m olar tooth were selected from 3418 collections in our department. Group I: inclu ding 18 teeth without obvious attrition, representing those of young age. Group Ⅱ: including 26 teeth with serious attrition, representing the aged ones. Group Ⅲ: including 18 teeth with deep carries on their occlusal surface, representi ng the weak functioning ones. Only those with two roots were included to make th e measurement comparatively. Three-blind methods were taken through the study. RESULTS: It was found that the tooth crow ns in Group II inclined more medially than those in Group I (P<0.01). No dif ference was found between Group I and Ⅲ. CONCLUSION: In comparing with the non-wear tooth the long axis of the mandibular first mo lar t ooth with serious wear of occlusal surface inclined even significantly implying that the effect of occlusion functional stimulation may be involved.
