Abstract：
UNASSIGNED: 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).
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.

摘要：
■使用锥形束计算机断层扫描（CBCT）研究巴基斯坦人群中永久下颌切牙和犬的辅助管的发生率和根管形态的变化。
■在大学牙科学院进行了一项横断面研究，拉合尔大学,巴基斯坦在2020年1月至2022年9月获得机构道德许可后。数据包括111例患者的记录，其中包括444个永久性下颌切牙和222个永久性下颌犬齿。附件根,记录每颗牙齿的根管和Vertucci管构型。使用SPSSv20进行数据分析。对每个解剖参数计算描述性统计。卡方检验用于确定性别与辅助根和根管的存在的关联。
■在评估的111条记录中，男性占48.6％，女性占51.4％。在中央和侧切牙中未发现附件根。然而,在4.9%的犬科动物中发现了辅助根。中切牙副管的发生率，侧切牙和犬齿为18.9%，分别为25.2%和10.4%。具有副管的牙齿中最常见的管构型是III型，其次是II型和V型。
■没有一个中切牙或侧切牙显示辅助根，而在4.9％的犬科动物中检测到。发现副根管的频率为18.9％，中切牙占25.2%和10.4%，侧切牙和犬齿分别。最常见的运河配置是I型，其次是III型和II型。Type-V,VI和VII不太常见。
