“…Some goals are traditionally associated with access cavity preparation, such as direct access to the root canal, preservation of the pulp chamber floor, and total removal of the pulp chamber roof, among others [14]. Total removal or partial preservation of the roof has recently fueled controversy in the scientific community [9,15,16].…”

Objective: The present study assessed the fracture strength of teeth subjected to endodontic access cavity preparation on buccal surfaces, or with the aid of operating microscopy when compared to the conventional technique. Material and methods: Sixty mandibular incisors were split into four groups (n=15): conventional access cavity preparation (CCP); conservative (C); buccal surface (BS); and control. The canals were prepared and filled and the cavities were restored. A static compressive strength test was conducted until crown fracture. The force data were compiled and assessed statistically. Kolmogorov-Smirnov and Shapiro-Wilk tests were performed to assess normality, Levene’s test to assess variance homogeneity, the one-way ANOVA to compare fracture strength in the assessed groups. Tukey’s HSD test was used to determine whether the differences in the means were significant between the groups.Results: The experimental groups did not show any statistically significant differences in mean fracture strength (CCP = 585.65 N±107.64 N)(BS = 530.52 N±129.35 N) (C = 517.83 N±114.68 N). Conclusion: Therefore, the selection of surface or size of access cavity proposed did not influence the fracture strength of mandibular incisors when compared to conventional cavity preparation.

“…The survival of an endodontically treated tooth, especially one with a history of root perforation, depends on understanding the biological and mechanical outcomes as multifactorial events over the individual's life span. 10,12,25 Tooth type, strategic position of the tooth (or surface of the tooth) and the level of the perforation influence the complexity of treatment. In lateral perforations, the relation of the crestal bone to the perforation may favor a good prognosis and sealing.…”

Root perforation results in the communication between root canal walls and periodontal space (external tooth surface). It is commonly caused by an operative procedural accident or pathological alteration (such as extensive dental caries, and external or internal inflammatory root resorption). Different factors may predispose to this communication, such as the presence of pulp stones, calcification, resorptions, tooth malposition (unusual inclination in the arch, tipping or rotation), an extra-coronal restoration or intracanal posts. The diagnosis of dental pulp and/or periapical tissue previous to root perforation is an important predictor of prognosis (including such issues as clinically healthy pulp, inflamed or infected pulp, primary or secondary infection, and presence or absence of intracanal post). Clinical and imaging exams are necessary to identify root perforation. Cone-beam computed tomography constitutes an important resource for the diagnosis and prognosis of this clinical condition. Clinical factors influencing the prognosis and healing of root perforations include its treatment timeline, extent and location. A small root perforation, sealed immediately and apical to the crest bone and epithelial attachment, presents with a better prognosis. The three most widely recommended materials to seal root perforations have been calcium hydroxide, mineral trioxide aggregate and calcium silicate cements. This review aimed to discuss contemporary therapeutic alternatives to treat root canal perforations. Accordingly, the essential aspects for repairing this deleterious tissue injury will be addressed, including its diagnosis, prognosis, and a discussion about the materials actually suggested to seal root canal perforation.

“…Outra coerente ref lexão a ser desenvolvida quanto à barreira intraorifício se refere ao tipo de material a ser utilizado. A reconstrução coronária deve recuperar o desempenho biomecânico do dente tratado endodonticamente da forma mais semelhante possível à original [16]. Assim, o material de escolha para confecção de restaurações coronárias definitivas pós-tratamento endodôntico precisa promover o melhor selamento e possuir compatibilidade biológica, boa adesão às estruturas dentárias, fácil manipulação, estabilidade química na cavidade oral, estética e propriedades físicas adequadas [3].…”

Introduction: The coronary shield, known as the intra-orifice barrier, is defined as a placement of a restorative material at the entrance of the root canal orifice after 3mm of gutta-percha and aiming to increase the resistance of the tooth to the fracture in addition to preventing coronary infiltration. Objective: to report and discuss the existing data in the dental literature regarding the materials available to perform the intra-orifice barrier in endodontically treated teethand to indicate if the desired coronary shield is really achievable. Literature review: The materials analyzed were composite resin, glass ionomer cement (CIV), zinc oxide based materials, silver amalgam and mineral trioxide aggregate (MTA). Results: composites of resin and bulkfill / flow in their results when compared with other materials like MTA. Silver amalgam, zinc oxide-based materials, and CIV do not result in terms of intra-orifice barrier. MTA was favorable in relation to microleakage, but did not reinforce a root structure. Conclusion: No material restorer is able to completely protect the infiltrations.However, as conventional composite resins and bulk-fill flow are the materials with the best properties associated with satisfactory results, however, the need for scientific studies comparing the materials used as an intra-orifice barrier.
