are anatomical variations of the mandibular molars and identifying them radiographically can be challenging for the clinician, especially in specific areas such as endodontics. The objective this study was to determine the prevalence of evaluated in cone-beam computed tomography in a northern Peruvian population. The study design was descriptive and cross-sectional. The sample consisted of 2640 permanent mandibular first and second molar teeth evaluated by cone beam tomography. Non-probabilistic convenience sampling was used. For the analysis of , the axial and coronal views of the tomography were evaluated. Prevalence was evaluated according to sex and according to type of tooth and average length. The statistical analyses used were the chi-square test and Kruskal-Wallis H test to find the correlation of the variables. A prevalence of 2.5 % of was determined. According to sex, was present in 1.36 % in females and 1.14 % in males (p > 0.05). The tooth 4.6 obtained the highest prevalence with 1.33 % (p > 0.05) and the average length of found was 9.27 mm (p > 0.05). The prevalence of the evaluated in cone beam tomography in a northern Peruvian population is low. Sex does not influence its presentation. Mandibular first molars are the ones that present the greatest amount of this anatomical variation and the average length of the is less than 10 mm.
下颌磨牙存在解剖变异，对临床医生而言，通过影像学识别这些变异具有挑战性，尤其是在牙髓病学等特定领域。本研究的目的是确定秘鲁北部人群中锥形束计算机断层扫描评估的[具体变异名称未明确]的患病率。研究设计为描述性横断面研究。样本包括通过锥形束断层扫描评估的2640颗恒牙下颌第一和第二磨牙。采用非概率便利抽样。对于[具体变异名称未明确]的分析，评估了断层扫描的轴向和冠状视图。根据性别、牙齿类型和平均长度评估患病率。所使用的统计分析方法是卡方检验和Kruskal-Wallis H检验，以找出变量之间的相关性。确定[具体变异名称未明确]的患病率为2.5%。按性别划分，女性中[具体变异名称未明确]的患病率为1.36%，男性为1.14%（p>0.05）。牙齿4.6的患病率最高，为1.33%（p>0.05），所发现的[具体变异名称未明确]的平均长度为9.27毫米（p>0.05）。在秘鲁北部人群中，锥形束断层扫描评估的[具体变异名称未明确]的患病率较低。性别不影响其表现。下颌第一磨牙出现这种解剖变异的数量最多，且[具体变异名称未明确]的平均长度小于10毫米。
