Résumé :

<strong>Abstract</strong> The primary goal of endodontic therapy is the long-term retention of a functional tooth by preventing or treating apical periodontitis. However, there are many other factors that impact endodontic outcomes such as the quality of the restoration and structural integrity of the tooth after root canal preparation. There are various  access cavity designs involving the minimal removal of tooth structure that  have been described for gaining entry to pulp chambers during root canal treatment. Minimally invasive access cavity preparations have been proposed in End

Résumé :

Background: The access cavity is a critical stage in root canal therapy and it may influence the subsequent steps of the treatment. The new minimally invasive endodontic access cavity preparation concept aims to preserve sound tooth structure by conserving as much intact dentine as possible including the pulp chamber's roof, to keep the teeth from fracturing during and after endodontic treatment. While there is great interest in such access opening designs in numerous publications, still there is a lack of scientific evidence to support the application of such modern access cavity designs in c

Procedural errors in this initial phase, whether in position, depth, or extension, can inevitably compromise the outcome of the entire treatment.

Therefore, adhering to tissue preservation principles is essential even during access cavity preparation.

Additionally, the possible influence of endodontic access preparation on tooth color was investigated. Materials and methods Thirty intact human anterior teeth were used. Black adhesive tape with a 4 mm diameter window was used to standardize the enamel surface intended for color analysis. After the access cavity, preparation and the initial root canal

Abstract Aim: The aim of the study was to investigate the disinfecting efficacy of a standardized irrigating solution activated by ultrasonics or laser irradiation on mature dual-species biofilms at different root levels in vitro. Materials and Methods: Conventional access cavity preparations were done on 160 single-rooted mandibular premolar teeth with single canals. Freshly extracted oral microbial strains of Staphylococcus aureus, Streptococcus mutans, Enterococcus faecalis, and Candida albicans after biochemical confirmation were used to generate two discrete dual-species microbial inoculu

Résumé :

Teeth with calcific metamorphosis pose a challenge to the endodontist in achieving proper access, identification, and debridement of the root canal. With the conventional technique, radiographs and bur orientation have dictated the access cavity preparation, which leads to the removal of more sound tooth structure and iatrogenic errors. To overcome these issues, the recent diagnostic imaging techniques such as cone beam computed tomography followed by three-dimensional fabrication of template have been proposed, which aid the clinician to accurately locate and negotiate the obliterated canal.

ABSTRACT Aim: The aim of the study is to evaluate and compare the effect of access cavity designs on the polymicrobial biofilm disinfection of root canal system. Methods: One hundred and twenty molar teeth were selected and randomly divided into four groups (n = 30) on the basis of access cavity design: traditional access cavity (TEC), contracted access cavity (CAC), truss access cavity (TAC), and caries-driven access cavity (CDAC). After access preparation, the samples were contaminated for 2 weeks to grow polymicrobial mature biofilm. Microbial sampling from the root canals was performed wit

ABSTRACTAnatomical variations must be considered in clinical and radiographical evaluations during endodontic treatment. Access cavity modifications may be required for stress free entry to complex anatomy. Higher magnification and illumination can be useful for access cavity preparation and to recognize and locate additional canals. This article describes the diagnosis and clinical management of two clinical cases of three rooted maxillary premolars. (Eur J Dent 2009;3:62-66)

Information on the diet of anuran species based on gut content analyses have been published by numerous researchers, yet the details of the incision method used to open the abdominal cavity of preserved specimens in preparation for such examinations are rarely explained in the presented methods. Our objective is to formally propose an optimal incision into the pleuroperitoneal cavity of liquid-preserved anuran specimens to gain access to and permit easy removal of parts of the digestive tract in preparation for food spectrum analyses. In our experience, this U-shaped cut is easy to perform and

In the surgical treatment of echinococcosis, especially disseminated echinococcosis (DE) of the abdominal cavity, the main unresolved issues are reduced to determining the volume of preoperative preparation, questions of the stages of surgical interventions, determining tactics in relation to access and choosing the most appropriate method of eliminating the residual cavity and the method of treatment of the residual cavity (RC).

Precision medicine (PM) refers to the modifying of medical or dental treatment according to the individual features of each patient. Imaging has become a central part of PM since the last decade. PM takes into account and aims to exploit the specific profile of the patient’s unique biology and problem. Imaging plays an important role by providing morphologic and functional information, focusing and guiding treatment and assessing response to therapy. Image-guided treatment (IGT), or here specifically image-guided endodontics, is not a strategy that tries to optimize 3-D cleaning, shaping and d

New minimally invasive endodontic cavities have been described and proposed to preserve dentin (and enamel) through strategic access, including point endodontic access cavity (PEAC). There is no consensus to what extent PEAC contributes to tooth’s resistance to fracture, because there is no agreement on how PEAC should be performed. The purpose of the present study is to describe and classify four different types of PEACs and to examine if a dynamic navigation system /DNS) could allow planning and precisely executing these cavities in vitro.

Materials and Methods. In this in vitro study, 100 extracted healthy human mandibular molars were selected and divided into 10 groups ( n = 10 ). Healthy teeth in one group were considered the control group. In three groups, traditional access cavity preparation was done (groups A) without two marginal ridges (A1), with one marginal ridge (A2), and with two marginal ridges (A3).

Purpose: To evaluate the effect of endodontic access hole preparation and choice of luting cement on the fracture resistance of translucent zirconia (5Y) crowns. Materials and Methods: Polymethylmethacrylate (PMMA) dies, representing a prepared maxillary molar tooth, were milled. Translucent zirconia crowns were milled from 5Y (Cercon XTML) zirconia discs and sintered. Forty crowns were divided into four groups (n = 10 per group) based on access hole preparation (accessed, non-accessed) and type of luting cement (resin cement, resin modified glass ionomer (RMGI) cement).
