Cone beam CT evaluation of mandibular molar root canal morphology in a Turkish Cypriot population

Abstract

The current study is the first of its kind to include a Turkish Cypriot population and, thus, provides baseline data for these patients regarding appropriate root canal treatments.

Internal and external morphology of mandibular molars: An original micro‐CT study and meta‐analysis with review of implications for endodontic therapy

“…The characteristics of included studies are presented in Table . A total of 65 studies ( n = 23,846 teeth), including our original study, were considered eligible and were included in the meta‐analysis (Skidmore and Bjorndal, ; Pineda and Kuttler, ; Reichart and Metah, ; Vertucci, ; Walker and Quackenbush, ; Walker, ; Weine et al, ; Fabra‐Campos, ; Yew and Chan, ; Calişkan et al, ; Prakashchandra and Reddy, ; Kartal and Cimilli, ; Zaatar et al, ; Guerisoli et al, ; Sperber and Moreau, ; al‐Nazhan, ; Sidow et al, ; Gulabivala et al, ; Wasti et al, ; Duda et al, ; Sert and Bayirli, ; Sert et al, ; Zhang et al, ; Jung et al, ; von Arx, ; Ahmed et al, ; Peiris, ; Tu et al, ; Pattanshetti et al, ; Peiris et al, ; Rahimi et al, ; Al‐Qudah and Awawdeh, ; Chen et al, ; Rwenyonyi et al, ; Schäfer et al, ; Gu et al, ; Huang et al, ; Neelakantan et al, ; Wang et al, ; Bahammam and Bahammam, ; Cosić, ; Demirbuga et al, ; Jang et al, ; Silva et al, ; Khan et al, ; Lima et al, ; Caputo et al, ; Celikten et al, ; Kim et al, ; Min et al, ; Monsarrat et al, ; Wolf et al, ; Madani et al, ; Martins et al, ; Mohammadzadeh et al, ; Pawar et al, ; Pekiner et al, ; Pérez‐Heredia et al, ). There were 32 imaging studies, 31 cadaveric studies, and two intraoperative studies.…”

“…The literature related to root canal anatomy of the mandibular molars is inconsistent. Discrepancies in data among articles could be attributed to several factors such as methodological differences (de Pablo, ), technical problems during exploration of the endodontic anatomy (Vertucci, ), geographical region (Celikten et al, ), and genetics (Monsarrat et al, ). It is essential to know the anatomy of the root canal system to perform endodontic therapy successfully because knowledge of both regular and pathological morphology determines the parameters of root canal treatment and can significantly affect the outcome of therapy (Segura‐Egea et al, ).…”

“…Several authors have described complications after endodontic treatment caused by missed, unprepared, and unfilled canals (Vertucci, ; Abdel‐Aziz and Gomaa, ; Gambarini et al, ). This results in bacteria residing in the overlooked canals, causing infection (Celikten et al, ). Anatomical variations such as accessory canals or apical deltas can cause both primary and secondary canal infections (Ahmed et al, ).…”

Morphology of Root Canal System of Maxillary and Mandibular Molars

“…The morphology of mandibular first molar has been investigated in different studies among different populations. The incidence of three-rooted teeth has been reported in some populations: Korea (25.8%) [51], Spain (4.1%) [33], and Turkey (3.6%) [52]; this third root is mostly located distolingually, and it is smaller than the distobuccal root. Root canal system varies from two canals to four canals.…”

Study of internal morphology of root-canal treated single-rooted mandibular second molars in a Greek population

“…Second mandibular molars present with varying anatomic features regarding the number of roots and the prevalence of different root canal configurations in each root. The most frequent morphology of these teeth is the two-rooted type, resembling the morphology of the first mandibular molar, with an incidence of 57.4%-95.7% 2,3 with the three-and four-rooted variants being considered rare according to the literature: ranging from 0.4%-9.0% 3,4 and 0.2% -0.9% 3,5 respectively. Single-rooted mandibular second molars show a remarkably wide range of incidence, varying from 1.3% to 41.2% 2,5 (Table 1).…”
