OBJECTIVE The aim was to evaluate the influence of multiple factors on the periapical status of endodontically treated (ET) teeth. METHODS The patients were clinically and radiographically reevaluated after root canal therapy. The quality of the root-filled canals, coronal restorations, intraradicular posts, dental caries, and periodontal parameters were associated with the teeth's periapical...

OE — Volume 32, Number 4, April 2006 he final objective of endodontic procedures should be the total obturation of the root canal space. Biologic necessity requires the elimination of the protein degradation roducts, bacteria, and bacterial toxins which emanate from necrotic and gangrenous oot canals. While these irritants may be eliminated by extraction of the tooth, the health f the dentition...

Relevance . The growing prevalence of combined endo-perio lesions (EPL) attracts the interest researchers. Insufficiently covered in scientific literature, issues anatomical and functional relationship between periodontal tissues dental pulp, lack an algorithm for diagnosis treatment EPL determine need their research. study aimed to arrange available data on morpho-functional aspects pulp featu...

The purpose of this study was to compare, in vitro, by means of computerized analysis of digital radiographic images, the anatomic alterations produced in the mandibular molar tooth dentinal walls of mesiobucal canals with severe curvature by three different endodontic techniques: Progressive Preparation, Staged and Serial Preparation. A selection was made of 45 extracted, human, mandibular mol...

This paper reports a case of gemination in a maxillary lateral incisor with two root canals and crown-root dilaceration. A 16-year-old male patient was referred for endodontic treatment of the maxillary left lateral incisor and evaluation of esthetic and functional complaints in the anterior region. The patient reported trauma to the anterior primary teeth. There was no spontaneous pain, but th...

AIM The aim of this clinical article is to describe the unusual anatomy that was detected in a maxillary first molar during routine endodontic treatment. BACKGROUND Variation in Root and Root canal morphology especially in multirooted teeth presents a constant challenge for a clinician in their detection and management. The literature is replete with cases that have extra canal or Root but ca...

The success of endodontic treatment depends on the identification of all root canals so that they can be cleaned, shaped, and obturated. This study investigated internal morphology of maxillary first molars by 3 different methods: ex vivo, clinical, and cone beam computed tomography (CBCT) analysis. In all these different methods, the number of additional root canals and their locations, the nu...

BACKGROUND Reciproc instruments are the only contemporary root canal instruments where glide path preparation is no longer strictly demanded by the manufacturer. As the complete preparation of root canals is associated with success in endodontic treatment we wanted to assess the ability and find predictors for Reciproc instruments to reach full working length (RFWL) in root canals of maxillary ...

AIM The present report describes and discusses root canal variations in the internal morphology of maxillary molars. BACKGROUND Dental internal anatomy is directly related to all the technical stages of the endodontic treatment. Even though, in some situations a typical anatomical characteristics can be faced, and the professional should be able to identify them. CASE DESCRIPTIONS This clin...

A sound knowledge of the normal tooth morphology and its numerous variations is essential to the success of endodontic therapy. While extra canals and lateral canals are routinely encountered and documented, there also exists the rare possibility of a fewer number of canals than normal. Early detection of such an occurrence is critical to the prevention of iatrogenic errors during endodontic tr...
