Abstract:
Successful endodontic treatment depends on cleaning and disinfecting the root canals, in order to provide conditions for three-dimensional filling, which should prevent root canal reinfection. However, anatomical complexities pose a challenge during endodontic treatment. The present study was a literature review carried out in the following databases: PubMed, SciELO, and MEDLINE, which were searched for articles published from 2017 to 2021. Micro-CT studies published in English, which analysed the capacity for preparation of oval and long-oval root canals, were included. The following keywords

Abstract:
Introduction. Oval root canals are all groups of human teeth. In such canals it is a challenge to fulfill the necessary preconditions for a successful outcome of root canal therapy - complete cleaning, shaping and obturation. Aim. The aim of this study was to investigate the shape and diameter of root canals in the apical and middle third of human mandibular molars and premolars, to determine the prevalence and extent of long oval canals. Materials and methods. The study was carried out on 80 extracted human teeth, 40 molars and 40 premolars. The teeth were placed in a specially designed muffl

Abstract:

 Introduction: Canals can be of different shapes in cross section including round canals, oval canals, long oval canals or ribbon shaped canals. Recesses of nonround canals may not be included in the round preparation created by rotary instruments and thus they remain unprepared. The aim of this study included determination of shape and taper of the apical root canal based on diameter at different levels.
 Methods: This was a cross sectional study which used convenient sampling technique to determine the sample size. Seventy extracted teeth were sectioned horizontally at one, two an

Abstract The aim of this study was to compare the bond strength (BS) of glass fiber posts (GFP) luted to oval and circular-shaped root canals rehabilitated using varying post techniques, at different intraradicular levels. Ninety 16-mm-long roots of human mandibular premolars, classified either as having oval or circular-shaped canals, were endodontically treated and prepared for restoration using one of three different post techniques (n=15): 1) single GFP; 2) resin-relined GFP; 3) main GFP associated with accessory posts.

Objectives. To investigate the root morphology and root canal anatomy of maxillary first premolar using microscopic computed tomography (micro-CT). Methods. 324 maxillary first premolars were collected and scanned. The root and canal diameter, canal wall thickness, root taper, and cross-sectional shapes were determined in the single root with 1 canal (SR1C), single root with 2 canals (SR2C), and 2 roots with 2 canals (2R2C) by micro-CT. Results. The results showed that single-rooted maxillary premolars were more common than other types. The incidence of SR1C, SR2C, and 2R2C reached 25%, 26.39%

The root canal system is considering the most important factor in endodontic treatment, due to the complexity of its anatomy and morphology. The aim of this study was to evaluate the cross-sectional root canal shape in three thirds (coronal, middle, apical) in different age groups using cone-beam computed tomography scanning (CBCT) and to present a new classification for root canal shape changes. This cross-sectional study included 300 CBCT scans for patient aged 20–70, and these scans were evaluated to study the morphology of the cross-sectional root canal shape in coronal, middle, and apical

The TRUShape 3D Conforming File (TRUShape), a novel, S-shaped nickel-titanium (NiTi) rotary file, was developed to facilitate cleaning and shaping of irregular-shaped root canals. The purpose of this study was to evaluate the shaping ability of TRUShape compared to Vortex Blue (VB) when used in non-round, oval-shaped root canals by micro-computed tomography (MCT). Thirty single-rooted human mandibular premolar teeth with radiographically similar root canal size and curvature were randomly allocated to two groups (N=15), and mechanically prepared with TRUShape or VB.

Os instrumentos endodônticos de níquel-titânio (NiTi) influenciaram positivamente o preparo dos canais radiculares. Entretanto, algumas dificuldades inerentes à própria anatomia do sistema endodôntico, permanecem. Canais radiculares com secção transversal oval longa dificultam a ação dos instrumentos rotatórios, os quais não conseguem se adaptar às suas paredes em toda extensão. O sistema Reciproc de lima única (VDW, Munique, Alemanha), recentemente lançado, foi desenvolvido para o preparo do canal radicular pela técnica de movimento de trabalho recíproco.

A ação do instrumento endodôntico nas paredes do canal leva à formação de debris dentinários. Sua remoção é principalmente função das manobras de irrigação. Entretanto, a ação do instrumento pode facilitar ou não o acúmulo dos debris dentinários, principalmente em função da sua cinemática. O sistema Twisted File (TF) Adaptive (SybronEndo, Orange, CA) combina o movimento rotatório contínuo e reciprocante e o sistema Reciproc (VDW, Munique, Alemanha) realiza o preparo do canal radicular pelo movimento reciprocante puro.
