An Evaluation of the Root Canal Anatomy of Mandibular Incisors in Turkish Population with Cone-Beam Computed Tomography (CBCT)

Aim: The achievement of root canal treatment is influenced by the status of the root canals. The aim of this study was to investigate the frequency of second root canals in mandibular incisors and the prevalence of root canal separation in the cervical, middle and apical thirds of cases with 2 root canals. Methodology: Retrospective cone-beam computed tomography (CBCT) datas of 500 patients seen between 2016 and 2018 were evaluated. A total of 300 patients, 134 males and 166 females, aged 13-71 years (mean age 39.34±13.44) were included in this study. A total of 587 central mandibular incisors and 582 lateral mandibular incisors were examined. The number of roots and root canal morphology based on the Vertucci’s classification were analyzed. The effect of gender on the prevalence of root canal anatomy was also evaluated. Results: The occurence of more than 1 root canal in mandibular lateral and mandibular central was 41.2% and 40.4% respectively and all teeth had a single root. Type I (59.2%) was the most common type, followed by Type III (31.4%), Type II (5.8%), Type VII (2.1 %), Type VI (0.8%) and Type V (0.7%). Type IV and Type VIII were not observed. The root canal separation in two root canaI of central and lateral mandibular incisors was found in the middle third of the root in 65.4% and 74.6%, respectively. The incidence of Type III in males (39%) was higher than that of females (25.4%), while the incidences of Type I in females (67.7%) were significantly higher than that of males (48.3%). The prevalence of second canals in mandibular incisors were detected more frequently in men than in women. Conclusion: The prevalence of second canal in total mandibular incisors is 40.8% (Type III was observed the most frequently). CBCT is an appropriate method for identifying of canal morphologies of mandibular incisors. How to cite this article: Çoban Kanyılmaz AN, Okumuş Ö, Sunay H.

Objective: The complex root canal anatomy is inherently colonised by microbial flora. Endodontic treatment success is always related to adequate disinfection of the root canal space, which ultimately affects the treatment outcome. A thorough understanding of the external and internal root canal anatomy by using adequately imaging modalities is essential before planning any treatment. The aim of this study was to investigate the number and morphology of the root canals of maxillary and mandibular premolars in Chennai population. Material and Methods: Full-size cone-beam computed tomographic images were randomly collected from 100 patients, resulting in a total of 200 first and 200 second maxillary premolars as well as 200 first and 200 second mandibular premolars. All the eight premolars were analysed in single patients, who underwent cone-beam computed tomography scanning during pre-operative assessment (before implant surgery, orthodontic treatment, diagnosis of dental-alveolar trauma or difficult root canal treatment). Total number of roots and root canals, frequency and correlations between men and women were recorded and statistically analysed by using chi-square tests. The root canal configurations were rated according to the Vertucci’s classification. Results: In the maxillary first premolar group (n = 200), 36.3% had 1 root, 56.7% had 2 roots and 7.0% had 3 roots, with most exhibiting a type IV canal configuration. In the maxillary second premolar group (n = 200), 60% had 1 root, 29.8% had 2 roots and 10.2% had 3 roots, with the majority of single-rooted second premolars exhibiting a type I canal configuration. In the mandibular first premolar group (n = 200), 80.5% had 1 root, 9.8% had 2 roots and 5% had 3 roots. In the mandibular second premolar group (n=200), 90.1% had 1 root, 6.4% had 2 roots and 3.5 % had 3 roots, with most exhibiting a type I canal configuration. No statistical correlation was found between number of roots, gender and tooth position. Conclusion: This cone-beam computed tomographic study confirmed previous anatomical and morphological investigations. Therefore, the possibility of additional root canals should be considered when treating premolars. Keywords: Cone-beam computed tomography; Mandibular; Maxillary; Premolar; Root canal; Morphology.

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.

ABSTRACT Objective: The aim of this study was to determine the root and canal morphology of the maxillary and mandibular anterior teeth in a Turkish population by analyzing cone-beam computed tomography (CBCT) images. Materials and Methods: CBCT images of 417 females and 410 males with a mean age of ranging from 14 to 70 years were examined in this study. A total of 1453 maxillary central incisors, 1504 maxillary lateral incisors, 1523 maxillary canines, 1582 mandibular central incisors, 1603 mandibular lateral incisors, and 1604 mandibular canines were analyzed. The number of root canals and the canal configurations were investigated and then were classified according to Vertucci's classification. The data were analyzed with the Pearson Chi-square test. Results: The Type 1 canal configuration was most prevalent in the maxillary anterior teeth (96.8-99.7%). The Types 2, 3, 4, and 5 canal configurations were observed within the range of 0-1.3%, 0-0.8%, 0-0.7%, and 0-1.8%, respectively. In the mandibular anterior teeth, the Type 1 canal configuration was most prevalent (77-95%). The Types 2, 3, 4, and 5 canal configurations were observed within a range of 0.2-2.7%, 0.2-1.6%, 0.9-5.9%, and 1.8-14.4%, respectively. The prevalence of two canals was higher in males than in females both in the maxillary and mandibular anterior teeth (P < 0.05). Conclusions: Type 1 was the most prevalent canal configuration of maxillary and mandibular anterior teeth in the Turkish population. Type 5 was the most frequently observed canal configuration of the two canalled teeth. The incidence of root canal numbers and configurations differed with sex.

Mandibular Incisors

SummaryBackground/Aim: To analyze the internal morphology of mandibular incisors with two root canals using cone-beam computed tomography (CBCT). Material and Methods: 289 (143 central and 146 lateral) extracted intact mandibular incisors were radiographed for detection of a second root canal. The teeth presenting a second root canal were imaged with CBCT and evaluated regarding: root canal type, the distance of the cementoenamel junction (CEJ) to the bifurcation of the canals and the distance of the canal fusion to the apical foramen (in teeth in which canals rejoined). Results: Out of 143 central and 146 lateral mandibular incisors, 41 (28.7%) and 44 (30.1%) teeth respectively showed a second root canal. Types II, III, V and an additional type to Vertucci’s classification were identified. Type III was the most prevalent and presented in 30 (73.2%) central and 34 (77.3%) lateral mandibular incisors with two root canals. The mean values of the distance of the CEJ to the canal bifurcation were 4.2 mm and 4.0 mm for central and lateral mandibular incisors respectively. The mean values of the distance of the canal fusion to the apical foramen 5.5 mm and 5.1 mm for central and lateral mandibular incisors respectively. Conclusions: Mandibular incisors with two root canals mainly present with Vertucci’s Type 3 canal configuration. The canal bifurcation was identified mostly at the coronal and middle thirds of the root, while the canal fusion occurred in the middle third of the root.
