Abstract

BACKGROUND

This study assessed the internal morphology of maxillary canines (MxC) through a systematic review of existing literature.

METHODS

Research articles up to June 2024 were retrieved from five electronic databases (MEDLINE via PubMed, Embase, Scopus, LILACS, and Cochrane). Predefined search terms and keywords were used, and potential studies were identified by cross-referencing and bibliographies of the selected articles reviewed.

RESULTS

Two hundred studies were identified, 73 duplicates were removed, 127 records were screened, and 113 were removed after consultation of title and abstract. After full-text consultation and hand searching, finally 22 studies were included. Using the method for describing the root canal configuration (RCC) of Briseño Marroquín et al. (2015) and Vertucci (Ve) (1984), the most frequently reported RCC of MxC were 1-1-1/1 (Ve I, 75.4-100%), 2-2-1/1 (Ve II, 0.1-20%), 1-2-1/1 (Ve III, 0.1-11.6%), 2-2-2/2 (Ve IV, 0.1-0.4%), 1-1-2/2 (Ve V, 0.1-2.4%), 2-1-2/2 (Ve VI, 0.5-1.2%), and 1-2-1/2 (Ve VII, 0.1-0.2%). The meta-analysis of six studies (Europe/Asia) showed that a significantly higher number of RCC of 2-2-1/1 (Ve II) (OR [95%CI] = 1.34 [0.53, 3.41]), 1-2-1/1 (Ve III) (OR [95%CI] = 2.07 [1.01, 4.26]), and 1-1-2/2 (Ve V) (OR [95%CI] = 2.93 [1.07, 8.07]), were observed in males, and 2-2-2/2 (Ve IV) (OR [95%CI] = 0.08 [0.00, 4.00]) in females. No sex differences in the RCC of 1-1-1/1 (Ve I) and 1-2-1/2 (Ve VII) were observed.

CONCLUSIONS

Cone beam computed tomography is the most frequently used method for research on the RCC of MxC. Despite the high prevalence of type 1-1-1/1 (Ve I) RCC in MxC, clinicians should remain vigilant for more complex and sex-differentiated patterns in up to 25% of cases to prevent endodontic treatment complications or failures.

摘要

背景

本研究通过系统综述现有文献，评估了上颌尖牙（MxC）的内部形态。

方法

检索了截至 2024 年 6 月的五个电子数据库（PubMed 中的 MEDLINE、Embase、Scopus、LILACS 和 Cochrane）中的研究文章。使用了预设的检索词和关键词，并通过交叉参考和选定文章的参考文献确定了潜在的研究。

结果

共确定了 200 项研究，去除了 73 项重复项，筛选了 127 项记录，在查阅标题和摘要后去除了 113 项。经过全文咨询和手工搜索，最终纳入了 22 项研究。使用 Briseño Marroquín 等人（2015 年）和 Vertucci（Ve）（1984 年）描述根管形态（RCC）的方法，MxC 最常报告的 RCC 是 1-1-1/1（Ve I，75.4%-100%）、2-2-1/1（Ve II，0.1%-20%）、1-2-1/1（Ve III，0.1%-11.6%）、2-2-2/2（Ve IV，0.1%-0.4%）、1-1-2/2（Ve V，0.1%-2.4%）、2-1-2/2（Ve VI，0.5%-1.2%）和 1-2-1/2（Ve VII，0.1%-0.2%）。六项研究（欧洲/亚洲）的荟萃分析表明，男性中 RCC 为 2-2-1/1（Ve II）（OR [95%CI] = 1.34 [0.53, 3.41]）、1-2-1/1（Ve III）（OR [95%CI] = 2.07 [1.01, 4.26]）和 1-1-2/2（Ve V）（OR [95%CI] = 2.93 [1.07, 8.07]）的比例明显更高，而女性中 RCC 为 2-2-2/2（Ve IV）（OR [95%CI] = 0.08 [0.00, 4.00]）的比例明显更高。在 RCC 为 1-1-1/1（Ve I）和 1-2-1/2（Ve VII）的情况下，未观察到性别差异。
