RESUMO
Aim: 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.
RESUMO
BACKGROUND Dental anxiety can impact oral health and dental treatment in patients of all age groups, which seems to be an obstacle to quality dental care. This systematic review of the literature aimed to evaluate the findings from cross-sectional studies conducted in the Kingdom of Saudi Arabia (KSA) on levels of dental anxiety (DA) between genders and among various demographic groups. MATERIAL AND METHODS An electronic search of PubMed, Embase, and Web of Science databases was carried out in January 2022. Studies that measured dental anxiety in Saudis in all regions of the KSA by direct evaluation and interviews were included. Studies that were not in the English language or used proxy measures were excluded. Quality assessment was carried out using Joanna Briggs Institute's critical appraisal tool for cross-sectional studies. RESULTS A total of 19 cross-sectional studies from the KSA were identified that used validated anxiety scales, including the Corah Dental Anxiety Scale (DAS), the Corah Dental Anxiety Scale, Revised (DAS-R), and the Modified Dental Anxiety Scale (MDAS). All studies were rated as having a high risk of bias. A mild level of DA was the most common among participants in the KSA. CONCLUSIONS The findings from this systematic review showed that in the KSA, although a mild level of dental anxiety was most common in the study participants, women, young adults, and university students showed a higher prevalence of dental anxiety. However, the lack of sufficient literature to support the current findings make an overall conclusion about DA extremely difficult.
