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. Methods: 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. Results: 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%). Conclusion: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.

“…Most permanent mandibular canines (PMCs) have one root and one canal [5][6][7][8][9]. PMCs with two roots and two canals occur at a prevalence of 0.0 to 12.1% worldwide and 0.2 to 2.9% in Saudi Arabia [5,6]. Although this root canal morphology is rare, dental clinicians must be aware of variations in the number of roots and canals for proper case management, as unpredicted findings in root canal morphology can have a significant negative impact on endodontic treatment outcomes.…”

Restorative and Endodontic Management of a Mandibular Canine With Two Roots and Two Canals: A Case Report

The existence of a permanent mandibular canine with two roots and two canals is rare. This case report presents restorative and endodontic management of a mandibular canine with two roots and two canals of a 32-year-old Saudi woman with multiple periradicular lesions of mandibular anterior teeth. Cone beam computed tomography (CBCT) was used for accurate diagnosis of the root canal morphology. CBCT helped to accomplish the restorative and endodontic treatment in a conservative approach.

“…The growing evidence demonstrated the incidence of the additional root in different types of teeth. The accessory root revealed approximately 0.8% at the palatal root of permanent maxillary first molars in the Greece-Turkish population [ 20 ], around 8% in permanent mandibular second premolars of the Indian population [ 21 ], up to 12% in permanent mandibular canines of the Iranian population [ 22 ], and almost 16% in permanent mandibular first premolars of the African-American population, respectively [ 23 ]. For PMFM, an earliest systematic review of the scope investigated that the pooled prevalence of three-rooted PMFM revealed 13% with the highest value of 22% in the Chinese population [ 24 ].…”

Introduction. Although numerous amounts of high-level evidence were present, they solely emphasized the tooth-level prevalence of three-rooted permanent mandibular first molar. Global patient-level prevalence and bilateral symmetrical distribution of this type of teeth were needed to be tackled across the world. The research question was “What is the global prevalence of three-rooted permanent mandibular first molars?” Materials and Methods. In vivo epidemiological studies undergone with Cone Beam Computed Tomography (CBCT) were eligible. The proportions of the prevalence of three-rooted permanent mandibular first molars were presented in the forest plots by random effect model. The calculation was performed with MetaXL version 5.3. Subgroup analysis, sensitivity analysis, and publication bias method were also calculated. Results. Seventy-two studies from 31 countries were selected for both qualitative and quantitative analyses. 26302 patients and 37994 permanent mandibular first molars were included in the analysis. 9% of permanent mandibular first molars all over the world demonstrated 3 roots. These three-rooted teeth were found in 10% of the world population, more than 45% of which revealed bilateral symmetry of that anatomy. Right-side dominance and no sexual dimorphism were seen in the distribution of three-rooted permanent mandibular first molars. Global tooth-level prevalence of Radix Entomolaris and Radix Paramolaris was 12% and 0.1%, respectively. Conclusion. The prevalence of three-rooted permanent mandibular first molars (PMFMs) was influenced by different geographical locations across the world and also by widespread habitation of the Mongoloid descent. The authors postulate that globalization, together with blending among ethnicities, may have a great impact on the reduction or accentuation of the anatomical significance in some populations.
