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

 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.

ABSTRACT Cleaning and shaping of root canal system forms the most important step in root canal root canal therapy. Unfortunately most of the instruments and techniques advocated are unable to remove residual debris and bacteria, ultimately resulting in pain and failure. To eliminate the causes of pain, and ensure success, we must use instruments and employ a technique that can best accomplish proper cleaning and shaping. Virtually all canals have parallel walls, and are curved and oval in shape. Hence tapered instruments are unable to clean the canal effectively and increase the chances of led

Abstract:

Compliance with the algorithms of endodontic treatment in most cases ensures the quality of treatment. However, real, long-term and sometimes immediate results that occur in clinical practice are not always successful. In general, the main reason for the unfavorable outcome of dental treatment is an incomplete sanitation of the root canal system. Modern publications by J. F. Siqueira, I. N. Rocas, and D. Ricucci (2019) note that many issues of endodontic treatment are unresolved. It follows that improving the quality of endodontic treatment is still relevant.Aim. To compare two systems of inst

Abstract Objective This study aimed to assess and compare XP-Endo Finisher (XP) cleaning efficiency with respect to the amount of remaining debris and smear layer versus Max-I-Probe needle (CI), EndoActivator device (EA), and combination of XP-Endo Finisher file with EndoActivator device (XP+EA) in oval root canals. Materials and Methods This in vitro study was performed on 36 extracted single root/canal mandibular premolars. Radiographic images were taken in buccolingual and mesiodistal projections to evaluate the shape of the root canal and determine whether it met exclusion criteria. All te

Abstract:

A primary aim of root canal treatment is to completely clean and shape the root canal system. Various instruments are available for endodontic instrumentation. Although rotary systems do prepare many canals without major procedural errors, they do not address canal types with long-oval or flat cross sections. A newly developed self-adjusting file (SAF) was designed to address the shortcomings of traditional rotary files by adjusting itself to the canal cross section. This instrument consists of a compressible opened NiTi tube that, on placement into a root canal, will exert pressure against th

Abstract:

Aim: The aim of this study was to evaluate the effects of two geometrically different fiber post systems and two different placing lengths on the stress distribution of endodontically treated teeth. Methodology: Four different mandibular premolar tooth models were created. These models were restored using oval or circular fiber posts with two different placing lengths. An oblique force of 300 N was applied to the top of the tooth, and von Mises stress evaluations were carried out on the dentin tissue, luting cement, and fiber posts. Results: The maximum von Mises stresses were obse
