In-depth knowledge of common and aberrant pulp morphology is essential for appropriate diagnosis and treatment planning before commencing root canal treatment. The radicular morphology of mandibular molars has been extensively studied. Considerable variation in the number of canals and roots found in these teeth has been reported.
The purpose of this study is to investigate the root canal morphology of the mandibular molars among the Rohilkhand population using Dentascan.
Dentascan images of mandibular molar were taken from 99 extracted teeth that were collected from the Department of Oral Surgery and Maxillofacial Surgery, Institute of Dental Sciences, Bareilly, and private clinics. The examination of root canal systems of the teeth was based on Vertucci's classification.
The mandibular molar ( = 99) were taken. Out of the 99 teeth examined, three canals were seen in 60 (60.6%) teeth, four canals in 39 (39.4%) teeth, 3% had extra distal roots, and 6% with C-shaped canals.
Among mandibular first molars, only 3% had three roots. Mesial roots of the first molar typically present with two canals and two apical foramina with type IV or II canal configuration. Most distal roots of the first molar presented with a type I canal configuration. The remainder were distributed mainly between types II, IV, III, and V. Among 99 mandibular molars, 6% had single C-shaped roots.
在开始根管治疗之前，深入了解正常和异常的牙髓形态对于进行恰当的诊断和治疗计划至关重要。下颌磨牙的根管形态已得到广泛研究。据报道，这些牙齿的根管和牙根数量存在相当大的变异。
本研究的目的是使用牙科扫描（Dentascan）研究罗希尔坎德人群中下颌磨牙的根管形态。
从位于巴雷利的牙科学院口腔外科和颌面外科以及私人诊所收集的99颗拔除的下颌磨牙获取牙科扫描图像。牙齿根管系统的检查基于韦尔图奇（Vertucci）分类法。
共获取了99颗下颌磨牙。在检查的99颗牙齿中，60颗（60.6%）牙齿可见三条根管，39颗（39.4%）牙齿可见四条根管，3%有额外的远中根，6%有C形根管。
在下颌第一磨牙中，仅有3%有三根。第一磨牙的近中根通常呈现两条根管和两个根尖孔，根管形态为IV型或II型。第一磨牙的大多数远中根呈现I型根管形态。其余主要分布在II型、IV型、III型和V型之间。在99颗下颌磨牙中，6%有单一的C形根。
