For the correct diagnosis and endodontic therapy, a complete understanding of root canal morphology is required. One of the causes of endodontic failure is the inability to identify every canal in the root canal system; the second mesiobuccal canal (MB2) in the permanent maxillary first molar is the most commonly missed canal. Studies examining the root canal differences in pediatric Indian populations' permanent maxillary first molars are somewhat uncommon.
Cone-beam computed tomography (CBCT) will be used to assess the root and canal morphology of permanent maxillary first molars in the pediatric Indian population.
In the age range of 7-13 years, 25 children's CBCT pictures (50 images) were gathered from the institutional database and private diagnostic facilities. SCANORA® software was used to reconstruct the CBCT pictures, and Statistical Package for the Social Sciences (SPSS) for Windows was used to evaluate and analyze the data.
The roots of each permanent maxillary first molar were distinct. And all of the palatal and distobuccal roots were found to have a single root canal (100%), whereas the mesiobuccal roots were found to have a single root canal in 80% of cases and a double root canal in 20% of cases. The Vertucci type II structure, followed by types IV and V, was the most prevalent in roots with two channels.
Within the constraints of this investigation, we came to the conclusion that the permanent maxillary first molar root canal configuration varied among the patients from the pediatric Indian population.

为了进行正确的诊断和牙髓治疗,需要全面了解根管形态。牙髓治疗失败的原因之一是无法识别根管系统中的每一个根管;上颌第一恒磨牙的第二近中颊根管(MB2)是最常被遗漏的根管。研究印度儿童人群上颌第一恒磨牙的根管差异的研究相对较少。
使用锥形束计算机断层扫描(CBCT)评估印度儿童人群上颌第一恒磨牙的牙根和根管形态。
在7至13岁年龄范围内,从机构数据库和私人诊断机构收集了25名儿童的CBCT图像(50张影像)。使用SCANORA®软件重建CBCT图像,并使用Windows版社会科学统计软件包(SPSS)对数据进行评估和分析。
每颗上颌第一恒磨牙的牙根都各不相同。所有腭根和远中颊根均发现有单一根管(100%),而近中颊根在80%的病例中发现有单一根管,20%的病例中有双根管。在有两个根管的牙根中,最常见的是Vertucci II型结构,其次是IV型和V型。
在本研究的限制范围内,我们得出结论,印度儿童人群患者的上颌第一恒磨牙根管形态各不相同。
