Abstract

AIMS

The purpose of this study was to evaluate and compare the fracture resistance of endodontically treated teeth using three different intra-orifice barriers.

SETTINGS AND DESIGN

This study was conducted at the department of conservative dentistry and endodontics, an study.

SUBJECTS AND METHODS

Forty freshly extracted single-rooted mandibular bicuspids ( = 40) were decoronated to obtain a 14-mm standard root length and all the canals were enlarged with ProTaper up to size F3 and they were obturated with gutta-percha using AH Plus sealer and randomly divided into 4 groups ( = 10). Group I: Control group obturated with gutta-percha only. Groups II, III, and IV had placement of intra-orifice barriers after the removal of 3-mm coronal gutta-percha such that Group II: Ever X posterior; Group III: Beautifil II; and Group IV: Tetric N-Ceram. Mounting of specimens was done in acrylic resin to expose coronal 3 mm and tested using the universal testing machine.

STATISTICAL ANALYSIS USED

Data were analyzed for significance by ANOVA and Tukey's test.

RESULTS

Ever X posterior group showed better fracture resistance and the control group is the least among the groups.

CONCLUSIONS

Placement of intra-orifice barriers significantly improves the fracture resistance compared with the control group.

摘要

目的

本研究的目的是评估和比较使用三种不同的根管口屏障对经根管治疗的牙齿的抗折性。

设置与设计

本研究在保守牙科与牙髓病科进行，是一项……研究。

研究对象与方法

40颗新鲜拔除的单根下颌双尖牙（n = 40）去冠以获得14毫米的标准根长，所有根管均用ProTaper扩大至F3号，并用AH Plus封闭剂进行牙胶尖充填，然后随机分为4组（n = 10）。第一组：仅用牙胶尖充填的对照组。第二、三、四组在去除3毫米冠部牙胶尖后放置根管口屏障，其中第二组：Ever X posterior；第三组：Beautifil II；第四组：Tetric N-Ceram。将标本固定在丙烯酸树脂中，使冠部3毫米暴露在外，并用万能试验机进行测试。

所用统计分析方法

数据采用方差分析和Tukey检验进行显著性分析。

结果

Ever X posterior组显示出更好的抗折性，对照组在各组中抗折性最差。

结论

与对照组相比，放置根管口屏障可显著提高抗折性。
