摘要

目的:利用锥形束计算机断层扫描(CBCT)技术,研究巴基斯坦海得拉巴人口中上颌和下颌前臼齿的平均齿长和根管构造:利用锥形束计算机断层扫描(CBCT)技术,调查巴基斯坦海得拉巴人口中上颌和下颌前臼齿的平均齿长和根管构造:观察研究。研究地点和时间:研究地点和时间:巴基斯坦信德省贾姆索罗利亚卡特医科大学牙科和牙髓病学系,2022 年 12 月至 2023 年 3 月:通过对 CBCT 扫描进行回顾性分析,评估了巴基斯坦亚群中 536 颗下颌和上颌前磨牙的牙齿长度、牙根数量和根管结构。数据分析采用了描述性统计、卡方检验和单向方差分析,以确定各种因素与根管形态之间的关联:结果:Vertucci 1 型(单根根管)是上颌前磨牙最常见的形态,频率在 46.3% 到 52.2% 之间。所有 8 颗前磨牙的平均长度在 20.56 毫米至 21.58 毫米之间。小部分上颌和下颌前磨牙的牙槽骨呈 C 形,其中 C1 最为常见。性别与牙槽构型或牙齿长度之间以及不同牙槽构型之间的牙齿长度之间均无明显关联:结论:Vertucci 1 型是上颌前磨牙最常见的结构,其次是 Vertucci 4 型。单根前臼齿较为常见,而双根配置则较少见。小部分前臼齿出现 C 形牙槽骨构型,下颌前臼齿出现的频率较高:锥形束计算机断层扫描 牙体解剖学 牙髓病学 前磨牙 根管形态学

Root Canal Morphology of Premolars in Population of Hyderabad, Pakistan: A Cone Beam Computerised Tomographic Analysis.

Objective: To investigate the mean tooth length and root canal configuration of human maxillary and mandibular premolars in the population of Hyderabad, Pakistan, using Cone Beam Computed Tomography (CBCT).

Study design: Observational study. Place and Duration of the Study: Department of Operative Dentistry and Endodontics, Liaquat University of Medical and Health Sciences, Jamshoro, Sindh, Pakistan, from December 2022 to March 2023.

Methodology: Using retrospective analysis of CBCT scans, tooth length, the number of roots, and root canal configuration of 536 mandibular and maxillary premolars were assessed in the subpopulation of Pakistan. The data were analysed employing descriptive statistics, Chi-square tests, and One-Way ANOVA to determine the association between various factors and root canal morphology.

Results: Vertucci Type 1 (one canal) was the most common configuration in maxillary premolars, with frequencies ranging from 46.3 to 52.2%. The mean length of all 8 premolars ranged from 20.56 mm to 21.58 mm. C-shaped canal configurations were observed in a small percentage of maxillary and mandibular premolars, with C1 being the most common. No significant association was found between gender and canal configuration or tooth length, and in tooth lengths among different canal configurations.

Conclusion: Vertucci Type 1 was the most common configuration in maxillary premolars, followed by Vertucci Type 4. Single-rooted premolars were more prevalent, while two-root configurations were less common. C-shaped canal configurations were observed in a small percentage of premolars, with higher frequency in mandibular premolars.

Key words: Cone beam computed tomography, Dental anatomy, Endodontics, Premolars, Root canal morphology.
