“…Such approaches are commonly used to facilitate the detection of MB2 canals (10, 19, 20); however, the abovementioned methods cannot reliably detect MB2 canals (15). The literature reveals that although MB2 canals of maxillary first molars have been found in more than 70% of in vitro studies (5, 7, 21, 22), they were detected clinically in less than 40% of cases (2, 23-25).…”

BackgroundThe localization of the additional canal orifice is one of the primary factors influencing the success of endodontic treatment. To deal with this problem, several techniques that each have their own advantages and disadvantages have been discussed in the literature.ObjectivesThe aim of the present in vitro study was to review a new approach to localizing second mesiobuccal (MB2) canals in maxillary first molars using cone beam computed tomography (CBCT).Patients and MethodsThe CBCT scans of 296 patients who were referred to the department of dentomaxillofacial radiology were included in the study. The presence of MB2 canals, the angle formed by the mesiobuccal, distobuccal, and palatal root canal orifices (∠MDP), and the angle formed by the mesiobuccal, distobuccal, and MB2 canal orifices (∠MDMB2) were evaluated on the axial section. Pearson correlation and multiple linear regression methods were used for all predictions. All of the analyses were performed using SPSS for windows version 22.0. A two-sided P value < 0.05 was defined as statistically significant.ResultsOf the 468 first molars, MB2 canals were observed in 296 subjects (141 females and 155 males). There were no statistically significant differences between females and males (P = 0.300). The ∠MDP and ∠MDMB2 were detected and evaluated. A moderate positive correlation was found between the ∠MDP and the ∠MDMB2. To predict the ∠MDMB2 values, it was shown that the ∠MDMB2 increased by 0.420 degrees when the ∠MDP increased by 1 degree. If the ∠MDP was greater than 90.95 degrees, there was a 78% probability that MB2 canals could be found.ConclusionThe determination of the presence of MB2 in the maxillary first molars may be carried out using CBCT scans. If the ∠MDP was 91 degrees or greater, there was considered to be a higher probability that MB2 canals would be found in the endodontic cavity. Due to the positive correlation between the ∠MDP and the ∠MDMB2, the localization of MB2 canals may be easily performed in relation to the main MB canal.

“…The internal anatomy of dental roots and canals has been assessed by clearing (6,10,11), in vitro endodontic access with radiography and instruments (12), radiographic examination (4), sectioning (13), in vitro macroscopic examination (14), and in vivo root canal therapy (RCT) with magnification (15). Cone-beam computed tomography (CBCT) scanning was introduced in the field of endodontics in 1990 (16).…”

ResumoIntrodução: Os tratamentos endodônticos têm evoluído com a finalidade de preparar o sistema de canais radiculares para receber uma obturação hermética deste sistema e assim preservar a saúde dos tecidos periapicais e/ou restabelecê-la, quando acometidos por lesões. Tais metas são alcançadas mediante obediência de uma adequada preparação químico-mecânica dos canais radiculares, seguida da obturação dos mesmos. Objetivo: Analisar o preparo químico-mecânico dos canais radiculares realizado in vitro pelos alunos do Curso de Odontologia da Universidade Federal do Espírito Santo, utilizando-se da diafanização. Material e método: Foram utilizados 88 espécimes dentários (caninos inferiores), cujo preparo químico-mecânico in vitro foi realizado pelos alunos. Esses dentes foram radiografados e posteriormente submetidos à técnica de diafanização. Nestes, se analisou a qualidade das técnicas de preparo químico-mecânico quanto à modelagem do canal radicular e, comparativamente, o melhor resultado das mesmas; visualizaram-se as características anatômicas do sistema de canais radiculares, e compararam-se o exame radiográfico e a diafanização dos dentes. Resultado: Quanto à modelagem dos canais radiculares analisados pela técnica da diafanização, 67% foram modelados com significância estatística de 0,002 (p<0,05) e, quanto à concordância dos resultados da variável modelagem do canal, entre o exame radiográfico e a técnica da diafanização, obteve-se um valor Kappa=0,511, mostrando uma concordância moderada entre as duas técnicas de visualização. Conclusão: A radiografia revelou-se limitada na visualização da modelagem dos canais e das características anatômicas do sistema de canais radiculares, e a diafanização é uma técnica de visualização acessível e imprescindível para a evolução do ensino na Endodontia.Descritores: Endodontia; preparo do canal radicular; diafanização. Abstract Introduction:The endodontic treatments have evolved in order to prepare the root canal system to receive a hermetic filling of the system and preserve the health of periapical and/or restore it when affected by tissue injury. These are achieved through obedience the a suitable chemical-mechanical preparation, then the filling of the same. Objective: Analyze the chemo-mechanical preparation of root canals performed in vitro by students of Dentistry of the Federal University of Espírito Santo, using the clearing technique. Material and method: 88 dental specimens (lower canines) were used, and provided to students who performed in vitro preparation chemo-mechanical. These specimens were radiographed and subsequently submitted to leaf clearing technique. The quality of the preparation chemical-mechanical techniques was examined concern the shaping of the root canal and compared the best result of the same, visualized the anatomical features of the root canal system, compared the radiographic exam of the teeth and clearing technique. Result: the modeling of root canals analyzed by the clearing technique, 67% were modeled with a statistical significan...

A comparison between clearing and radiographic techniques in the study of the root‐canal anatomy of maxillary first and second molars

Abstract: It is concluded that the agreement between the two radiographic examiners and the agreement between either radiographic examiner and the clearing technique were poor to moderate, indicating the limited value of radiographs alone when studying certain aspects of the root-canal system.
