A practical guide to endodontic access cavity preparation in molar teeth

British Dental Journal, 2007
The main objective of access cavity preparation is to identify the root canal entrances for subsequent preparation and obturation of the root canal system. Access cavity preparation can be one of the most challenging and frustrating aspects of endodontic treatment, but it is the key to successful treatment.

Effect of endodontic access cavity preparation on monolithic and ceramic veneered zirconia restorations.

Quintessence international (Berlin, Germany : 1985), 2017
Due to the high chipping rates observed in veneered zirconia ceramic restorations, the use of monolithic zirconia restorations has been recommended. This study tried to compare veneered and monolithic zirconia fixed dental prostheses (FDPs) with respect to the amount of damage induced by endodontic access preparation.Monolithic and ceramic veneered (n =

Student endodontic access cavity preparation: Performance versus perception

Journal of Endodontics, 1985
A voluntary critique of endodontic access preparations was offered to all graduating seniors upon completion of the terminal endodontic clinical post-test. The purpose of the critique session was to evaluate a student's self-assessment skills and to determine whether any benefits occur from the review.

[Principles for the preparation of the access cavity in teeth].

Nederlands tijdschrift voor tandheelkunde, 1990
In this article the general principles and techniques for the preparation of the endodontic access cavity are presented. Problems encountered during preparation are discussed more thoroughly, as are problems encountered while trying to locate the canal orifice(s). Instructions are given to prevent failure during this stage of endodontic treatment.

The effect of endodontic access cavity preparation and subsequent restorative procedures on molar crown retention

Australian Dental Journal, 1996
AbstractPreparation of an endodontic access cavity through a full crown may affect its retention. This study was undertaken to investigate the effects on molar crown retention of endodontic access cavities and their subsequent restoration. Thirty human molars were mounted in resin, crown preparations were cut and their surface areas were determined ...

A comparison of diamond and tungsten carbide burs for preparing endodontic access cavities through crowns

Journal of Endodontics, 1988
Diamond and tungsten carbide burs designed for cutting metal were tested with precious and nonprecious bonding alloys. Standard cavities were prepared and timed. Tungsten carbide burs were most effective in preparing cavities in precious alloy but only a coarse dome-shaped cylindrical diamond bur effectively prepared a succession of five cavities in ...

The effect of endodontic access cavity preparation and subsequent restorative procedures on incisor crown retention

Australian Dental Journal, 1994
AbstractEndodontic treatment often will require access through existing crowns. This study was undertaken to determine whether endodontic access cavity preparation affected the retention of crowns in anterior teeth and then to determine whether this retention can be regained by amalgam or post‐retained amalgam restorations.

[Access cavity preparation for mandibular incisors with suspected two canals].

Zhonghua ya yi xue hui za zhi, 1990
One of the common reasons for endodontic failure is incomplete root canal obturation. According to previous studies, about 10-45% of all lower incisors have two canals. The purposes of this study were: 1. determine the incidence of double canals in the lower incisors among Chinese; 2.

[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
