The root morphology and canal configuration (RMCC) of mandibular and maxillary canines among Saudi population is systematically reviewed and compared with international studies in this research.
This study was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. The electronic databases of PubMed, Science Direct, Scopus, Wiley Library, Google website search, and Web of Science were searched. Only local and international cross-sectional, comparative, evaluation, and validation studies or case reports published between 2016 and 2022 that directly evaluated canine RMCC and assessed participants using cone beam computed tomography were included.
Forty-three studies that investigated RMCCs (17 local and 26 international) were involved in this review. The original Saudi research recorded that almost 100% of maxillary canines had one root and one canal, whereas 98.4% and 94.1% had one root and one canal in the mandibular arch. Vertucci's class I had the highest percentages in the maxillary and mandibular arches at 98.3% and 95.8%, respectively, followed by class III with 0.7% and 1.9% for the same arches, respectively. International studies recorded that 100% of maxillary canines had one canal and root; the percentages of the mandibular arch were 92.3 and 98% for single canal and root, respectively; and the highest percentage was obtained by Vertucci's class I (91.1%), followed by class III (4.7%).
This review reports and confirmed the symmetry of the RMCCs of maxillary and mandibular canines between Saudi studies and other populations. Moreover, Vertucci's classes I and III were the most frequent RMCCs, and two-rooted canines in both arches were considerably less frequently than single-rooted ones.
本研究系统回顾了沙特人群中下颌和上颌尖牙的牙根形态和根管形态（RMCC），并与国际研究进行比较。
本研究按照系统评价和Meta分析的首选报告项目建议进行。检索了PubMed、Science Direct、Scopus、Wiley Library、谷歌网站搜索和Web of Science等电子数据库。仅纳入2016年至2022年间发表的直接评估尖牙RMCC并使用锥形束计算机断层扫描评估参与者的本地和国际横断面、比较、评估和验证研究或病例报告。
本综述纳入了43项调查RMCC的研究（17项本地研究和26项国际研究）。沙特的原始研究记录显示，几乎100%的上颌尖牙有一个牙根和一个根管，而下颌牙弓中这一比例分别为98.4%和94.1%。在上颌和下颌牙弓中，韦尔图奇I类的比例最高，分别为98.3%和95.8%，其次是III类，同一牙弓中的比例分别为0.7%和1.9%。国际研究记录显示，100%的上颌尖牙有一个根管和牙根；下颌牙弓中单根管和单牙根的比例分别为92.3%和98%；韦尔图奇I类的比例最高（91.1%），其次是III类（4.7%）。
本综述报告并证实了沙特研究与其他人群之间上颌和下颌尖牙RMCC的对称性。此外，韦尔图奇I类和III类是最常见的RMCC，两个牙弓中的双根尖牙比单根尖牙的频率要低得多。
