摘要

目的:比较牙髓治疗过的牙齿和其对侧正常牙齿的最大咬合力,并评估影响它们的口内因素:招募 30 名成年参与者,每组 15 名男性和女性,他们都有一颗牙髓治疗过的牙齿及其对侧的重要牙齿。使用无线传感器网络咬合力记录仪测量最大咬合力,并将根管治疗牙的平均最大咬合力与其对侧活力牙的平均最大咬合力进行比较。采用多因素方差分析研究各种临床因素与最大咬合力之间的关系:结果:根管治疗后牙齿的平均最大咬合力明显高于同侧牙齿(分别为 215.44 ± 74.11N 和 202.40 ± 70.67N)(P < 0.001)。在临床因素中,最大咬合力受牙齿位置(P < 0.01)和冠根比(P = 0.01)的显著影响。进一步分析牙髓治疗组和对照组,发现牙齿位置是唯一与最大咬合力相关的因素,P < 0.05:结论:从统计学角度看,根管治疗牙的最大咬合力明显高于相应的对侧牙。

A Case-Control, Split-Mouth Study Comparing Maximum Occlusal Forces in Endodontically Treated Teeth and Vital Counterparts.

Purpose: To compare the maximum occlusal force (MOF) in endodontically treated teeth (ETT) and their vital contralateral counterparts and to evaluate the intraoral factors affecting them.

Materials and methods: A total of 30 adult participants presenting with an endodontically treated tooth and its vital contralateral counterpart were recruited for this split-mouth study. MOFs were measured using a wireless sensor network occlusal force recorder, and the mean MOF of ETT was compared to that of their vital contralateral counterparts. Multiple-factor ANOVA was used to examine the association between various clinical factors and MOF.

Results: The mean MOF for ETT was significantly higher than their vital counterparts (215.44 ± 74.11 N and 202.40 ± 70.67 N, respectively; P < .001). Among the clinical factors, the MOFs were significantly influenced by the location of teeth (P < .01) and the crown-root ratio (P = .01). Upon further analysis of ETT and control teeth, the location of teeth was identified as the sole factor associated with MOF, with P < .05.

Conclusions: The MOFs for ETT were statistically significantly higher than those of their corresponding vital contralateral teeth.
