Anatomical variability in primary molars across geographic regions presents significant challenges in pediatric endodontics. Regional differences in root canal morphology complicate diagnosis and treatment planning, emphasizing the need for population-specific insights.
This review synthesizes evidence on geographical variations in root canal anatomy, focusing on population-specific characteristics and their clinical relevance.
Following PRISMA guidelines, databases including PubMed, Scopus, Web of Science, EBSCOhost, Embase, and the Cochrane Register were comprehensively searched. Studies employing advanced imaging modalities such as cone-beam computed tomography, micro-computed tomography, multidetector computed tomography, and nano-computed tomography to analyze root canal morphology were included. Observational studies describing root canal configurations and prevalence in primary molars were reviewed. A meta-analysis was performed to determine pooled prevalence rates and geographical trends for Vertucci canal configurations in maxillary and mandibular molars.
The analysis of 36 studies encompassing 4863 primary molars revealed significant regional variations. Australian maxillary molars exhibited a higher prevalence of fused roots, while Indian and Turkish mandibular molars displayed more accessory canals. Japanese molars were characterized by thinner dentin walls, reflecting population-specific trends in root canal anatomy.
Geographical variations in root canal morphology underscore the need for region-specific research and tailored treatment strategies in pediatric endodontics. Advanced imaging modalities play a pivotal role in improving diagnostic accuracy and optimizing clinical outcomes.
不同地理区域乳牙的解剖变异给儿童牙髓病学带来了重大挑战。根管形态的区域差异使诊断和治疗计划变得复杂，凸显了针对特定人群进行深入了解的必要性。
本综述综合了关于根管解剖结构地理差异的证据，重点关注特定人群的特征及其临床相关性。
遵循PRISMA指南，全面检索了包括PubMed、Scopus、Web of Science、EBSCOhost、Embase和Cochrane注册库在内的数据库。纳入了采用锥束计算机断层扫描、微计算机断层扫描、多探测器计算机断层扫描和纳米计算机断层扫描等先进成像方式来分析根管形态的研究。对描述乳牙根管形态和发生率的观察性研究进行了综述。进行了一项荟萃分析，以确定上颌和下颌磨牙中Vertucci根管形态的合并发生率和地理趋势。
对36项涉及4863颗乳牙的研究分析显示出显著的区域差异。澳大利亚上颌磨牙融合根的发生率较高，而印度和土耳其下颌磨牙的副根管更多。日本磨牙的特点是牙本质壁较薄，反映了根管解剖结构的特定人群趋势。
根管形态的地理差异强调了在儿童牙髓病学中开展针对特定区域的研究和制定个性化治疗策略的必要性。先进的成像方式在提高诊断准确性和优化临床结果方面发挥着关键作用。
