Evaluation of the root and canal morphology of mandibular permanent molars in a south-eastern Turkish population using cone-beam computed tomography

Abstract

Objective:The aim of this retrospective study was to determine the root and canal morphology of the mandibular first and second permanent molars in a Turkish population using cone-beam computed tomography (CBCT).Materials and Methods:CBCT images of mandibular first (n = 966) and second molar (n = 1165) teeth from 850 Turkish patients were evaluated. The root canal configurations were classified according to the method of Vertucci. The data were analyzed by Pearson's Chi-square test.Results:The majority of mandibular molars were two rooted with three canals; however, three roots were identified in 0.05% of the first molars and 0.01% of the second molars, and 100% of the additional root canals were of type I configuration. Mesial roots had more complex canal systems with more than one canal, whereas most distal roots had a type I configuration.Conclusions:Within the limitations of this study, it can be concluded that CBCT scanning provides supplemental information about the root canal configurations of mandibular molars in a Turkish population. This study may help clinicians in the root canal treatment of mandibular molars.

Cone-beam Computed Tomography Investigation of Middle Mesial Canals and Isthmuses in Mandibular First Molars in a Chinese Population

“…Mandibular first molars most typically have a total of 2 roots and 3 canals in the mesial and distal roots [20]. Different populations seem to exhibit different rates of additional mandibular molar roots, with rates of 22.7 % in Japanese patients [21], 15 % in patients from Hong Kong [22], and 29 % in those from China [23].…”

Estudo da Tomografia Computadorizada de Feixe Cônico na Avaliação Morfológica de Raízes e Canais dos Molares e Pré-Molares da População Brasileira

“…Porém há uma dificuldade de categorizar a população brasileira atual devido a sua diversidade (Silva et al, 2013). E essa dificuldade é expressa na baixa quantidade de trabalhos a respeito da avaliação morfologia de raízes e canais através da TCFC, quando comparado com outras populações como as da China (Zheng et al, 2010;Yu et al, 2012), Coreia Yang, 2012), Índia (Shetty et al, 2014), Tailândia e Turquia (Nur et al, 2014).…”

“…A configuração de canais é uma classificação reconhecida proposta por Vertucci (1984) Em estudos prévios também a um predomínio da configuração do tipo I para a raiz distal (Pablo et al, 2010;Nur et al, 2014).…”

“…Para a raiz mesial as configurações mais comuns encontradas foram do tipo IV (2-2) seguida do tipo II (2-1), também em concordância com a literatura (Pablo et al, 2010;Nur et al, 2014).…”

“…Neelakantan et al (2010a) ressalta ainda a vantagem do uso da técnica de TCFC poder ser utilizada em estudos in vivo. Rocha et al (1996) (Nur et al, 2014).…”
