Abstract

INTRODUCTION

The study examined mandibular premolars' root and canal distribution across genders and sides.

MATERIALS AND METHODS

Cone-beam computed tomography (CBCT) imaging of mandibular premolars was performed using SINORA ORTHOPHOS XG 3D, with specific parameters set.

RESULTS

Cone-beam computed tomography (CBCT) imaging of 100 participants revealed mostly single-rooted premolars, with slight variations, notably among females. Mandibular first premolars predominantly had single canals and roots, with a higher occurrence of two canals in females. Statistical analysis showed no significant gender- or side-based differences in root distribution. The findings underscore gender-specific variations in premolar morphology, highlighting the importance of tailored treatment planning, especially for the left side.

CONCLUSION

While CBCT proves valuable, further research is needed to optimize its utility in endodontic decision-making.

摘要

引言

本研究调查了下颌前磨牙牙根和根管在不同性别及不同侧别的分布情况。

材料与方法

使用SINORA ORTHOPHOS XG 3D对下颌前磨牙进行锥束计算机断层扫描（CBCT）成像，并设置了特定参数。

结果

对100名参与者的锥束计算机断层扫描（CBCT）成像显示，大多数下颌前磨牙为单根，略有差异，女性尤为明显。下颌第一前磨牙主要为单根管和单根，女性出现双根管的情况较多。统计分析表明，牙根分布在性别和侧别上均无显著差异。研究结果强调了前磨牙形态的性别特异性差异，突出了个性化治疗计划的重要性，尤其是针对左侧。

结论

虽然CBCT被证明具有价值，但仍需要进一步研究以优化其在牙髓病治疗决策中的应用。
