To study the prevalence of additional root canal orifices of upper first permanent molars in Saudi subpopulation in Jeddah, Kingdom of Saudi Arabia, utilizing micro-computed tomography X-ray (micro-CT).
One hundred extracted upper first permanent molars of Saudi patients were included in the study. Micro-CT was used to detect the prevalence of extra root canal orifices of the permanent upper first molars.
The evaluation of three-dimensional (3D) images of this study showed that of 100 upper permanent first molars scanned and analyzed, 10.53% had 6 pulp canal orifices, 35.09% had 5 pulp canal orifices, 47.37% had 4 pulp canal orifices and 7.01% had 3 pulp canal orifices.
The current data showed the highest prevalence of 4 and 5 root canal orifices compared to 3 and 6 root canal orifices.
The knowledge of anatomic variations of teeth before starting root canal treatment can help dentists to detect and manage all root canals successfully.
利用微计算机断层扫描X射线(微CT)研究沙特阿拉伯王国吉达地区沙特亚人群上颌第一恒磨牙额外根管口的患病率。
本研究纳入100颗沙特患者拔除的上颌第一恒磨牙。使用微CT检测上颌第一恒磨牙额外根管口的患病率。
本研究的三维(3D)图像评估显示,在扫描和分析的100颗上颌第一恒磨牙中,10.53%有6个牙髓根管口,35.09%有5个牙髓根管口,47.37%有4个牙髓根管口,7.01%有3个牙髓根管口。
当前数据显示,与3个和6个根管口相比,4个和5个根管口的患病率最高。
在开始根管治疗前了解牙齿的解剖变异有助于牙医成功检测和处理所有根管。
