Computer-aided design–based guided endodontic: A novel approach for root canal access cavity preparation

Proceedings of the Institution of mechanical engineers. Part H, journal of engineering in medicine, 2018
In cases of teeth with unusual morphology like calcified pulp canal, guided endodontic treatment is suggested. An endodontic guide which navigates burs according to a preplanned path is used.

Biomechanical behavior of maxillary premolars with conservative and traditional endodontic cavities.

Quintessence international (Berlin, Germany : 1985), 2019
The objective was to evaluate the effects of the configuration of endodontic cavities with parallel or divergent walls, versus traditional endodontic cavities, on stress distribution, fracture resistance, and fracture mode of maxillary premolars by using both fracture-strength and finite element tests.Thirty-two maxillary first premolars were divided ...

Sealing ability of intermediate restorations and cavity design used in endodontics

Oral Surgery, Oral Medicine, Oral Pathology, 1990
Temporary filling materials are used in endodontics to prevent contamination of the root canal system during intertreatment visits. Recently, a new composition resin (TERM) has been introduced as an interim restoration in endodontics. The purpose of this investigation was to evaluate the efficacy of this resin as an interim restoration and possible ...

Assessment of coronal microleakage in intermediately restored endodontic access cavities

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2002
The purpose of this in vitro study was to evaluate the coronal microleakage in endodontic access cavities restored with Kalzinol (zinc oxide eugenol, De Trey, Dentsply Dental Products of India Ltd) and a zinc oxide eugenol (ZOE) intermediate restorative material at different intervals.Restored access cavities were immersed in 2% freshly prepared ...

[Methodology for a rational approach to endodontic cavity access and canal preparation. Endodontic cavity access and pretreatment].

Revue d'odonto-stomatologie, 1990
The purpose of this study was to develop a protocol which allows for improved access cavity preparation in all clinical circumstances. From radiographic and clinical evaluation a systematic organization of 10 burs was found to be optimal for all cases encountered. This standard arrangement makes burs available for use in situations with varying loss of

Impact of contracted endodontic cavities on fracture resistance of endodontically treated teeth: a systematic review of in vitro studies

Clinical Oral Investigations, 2017
This systematic review was performed to answer the following question: do contracted endodontic cavities (CECs) increase resistance to fracture in extracted human teeth compared to traditional endodontic cavities (TECs)?A literature search without restrictions was carried out in PubMed, Science Direct, Scopus, Web of Science, and Open Grey databases ...

Fracture Strength of Endodontically Treated Teeth with Different Access Cavity Designs

Journal of Endodontics, 2017
The purpose of this study was to compare in vitro the fracture strength of root-filled and restored teeth with traditional endodontic cavity (TEC), conservative endodontic cavity (CEC), or ultraconservative "ninja" endodontic cavity (NEC) access.Extracted human intact maxillary and mandibular premolars and molars were selected and assigned to control ...
