To investigate the incidence of accessory canals and the variation in root canal morphology of permanent mandibular incisors and canines in Pakistani population using Cone Beam Computed Tomography (CBCT).
A cross-sectional study was conducted in University College of Dentistry, The University of Lahore, Pakistan after getting institutional ethical permission from January 2020 to September 2022. The data included records of 111 patients consisting of 444 permanent mandibular incisors and 222 permanent mandibular canines. Accessory root, root canals and Vertucci canal configuration for each tooth was recorded. Data analysis was done using SPSS v20. Descriptive statistics were calculated for each anatomical parameter. Chi-square test was applied to determine association of gender with the presence of accessory roots and root canals.
Among the 111 records evaluated, 48.6% were males and 51.4% were females. No accessory root was found in the central and lateral incisors. However, an accessory root was found in 4.9% of the canines. The incidence of accessory canals in the central incisors, lateral incisors and canines was 18.9%, 25.2% and 10.4% respectively. The most common canal configuration in teeth with accessory canals was Type-III, followed by Type-II and Type-V.
None of the central or lateral incisor showed accessory root while it was detected in 4.9% canines. The frequency of accessory root canal was found to be 18.9%, 25.2% and 10.4% in central incisors, lateral incisors and canines respectively. The most common canal configuration was Type-I, followed by Type-III and Type-II. Type-V, VI and VII were less common.
使用锥形束计算机断层扫描（CBCT）研究巴基斯坦人群中恒下颌切牙和尖牙的副根管发生率及根管形态变异。
在获得机构伦理许可后，于2020年1月至2022年9月在巴基斯坦拉合尔大学牙科学院进行了一项横断面研究。数据包括111例患者的记录，其中有444颗恒下颌切牙和222颗恒下颌尖牙。记录每颗牙齿的副根、根管和韦尔图奇根管形态。使用SPSS v20进行数据分析。计算每个解剖参数的描述性统计量。应用卡方检验确定性别与副根和根管存在情况之间的关联。
在评估的111份记录中，48.6%为男性，51.4%为女性。中切牙和侧切牙未发现副根。然而，4.9%的尖牙发现有副根。中切牙、侧切牙和尖牙的副根管发生率分别为18.9%、25.2%和10.4%。有副根管的牙齿中最常见的根管形态是III型，其次是II型和V型。
中切牙和侧切牙均未显示副根，而4.9%的尖牙检测到副根。中切牙、侧切牙和尖牙的副根管频率分别为18.9%、25.2%和10.4%。最常见的根管形态是I型，其次是III型和II型。V型、VI型和VII型较不常见。
