BACKGROUND
The aim of this study was to evaluate the relationship between Endodontic Access Cavity (EAC) types with MB2 canal detection ratio in the upper first molars.
METHODS
A total of 60 roots of extracted human maxillary first molars were selected. All teeth were prepared with Point EAC (PEAC), Conservative EAC (CEAC) and Traditional EAC (TEAC) respectively. After each group were completed, extra canal was searched. Preoperative and postoperative tooth weigh was calculated using precise scale. McNemar's chi-square test and a paired test significant difference were used for statistical analyses.
RESULTS
The EAC types statistically were changed of tooth tissue loss quantity (p = 0.000). MB2 detection rate of CEAC (%53,3) and TEAC (%60) are higher than statistically that of PEAC (%31.6) (p < 0.05). 8 teeth MB2 canal was detected only with the CBCT images.
CONCLUSIONS
In upper molars, CEAC seems reasonable in terms of detected the MB2 canal and removed hard tissue.
背景
本研究旨在评估上颌第一磨牙根管入口洞型（EAC）类型与MB2根管检出率之间的关系。
方法
共选取60颗拔除的人类上颌第一磨牙牙根。所有牙齿分别采用点状EAC（PEAC）、保守EAC（CEAC）和传统EAC（TEAC）进行预备。每组完成后，寻找额外根管。使用精确秤计算术前和术后牙齿重量。采用McNemar卡方检验和配对检验进行统计学分析。
结果
EAC类型在统计学上改变了牙齿组织损失量（p = 0.000）。CEAC（53.3%）和TEAC（60%）的MB2检出率在统计学上高于PEAC（31.6%）（p < 0.05）。仅通过CBCT图像检测到8颗牙齿的MB2根管。
结论
在上颌磨牙中，就检测MB2根管和去除硬组织而言，CEAC似乎是合理的。
