1. Restorative Possibilities Using Zirconia Ceramics for Single Crowns
Resumo Dois casos clínicos são apresentados para explorar as diferenças técnicas e discutir as vantagens e desvantagens de se utilizar zircônia com cerâmica estratificada ou monolítica para confeccionar coroas unitárias. O primeiro caso descreve os passos clínicos na confecção de uma coroa monolítica no segundo pré-molar esquerdo utilizando uma

3. Photodynamic therapy as an aiding in the endodontic treatment: case report
RESUMO Neste artigo descreve-se a aplicação da Terapia Fotodinâmica (PDT) como coadjuvante ao tratamento endodôntico realizado em dente permanente perfurado iatrogenicamente e portador de necrose pulpar. Após exame clínico e radiográfico, realizou-se a abertura coronária, curetagem da área da perfuração e preparo mecanizado com o sistema Reciproc

5. How biomechanics can affect the endodontic treated teeth and their restorative procedures?
Abstract: Endodontic treatment is a common dental procedure used for treating teeth which the pulp tissue has become irreversibly inflamed or necrotic as a result of the carious process or dental trauma. This procedure which involves mechanical and chemical preparation of root canal may affect several mechanical and physical properties of the tooth structure

6. Evaluation of bulk-fill systems: microtensile bond strength and non-destructive imaging of marginal adaptation
Abstract The objective of this study was to investigate microtensile bond strength (MTBS) and interfacial adaptation (IA) of bulk-fill restorative systems bonded to dentin in Class-I-preparations. Box-shaped preparations (4-mm-long, 3-mm-wide, 2-mm-high) made in extracted molars, and Teflon matrix with the same dimensions positioned over the occlusal surface

7. Effect of erosive challenges on deciduous teeth undergoing restorative procedures with different adhesive protocols - an in vitro study
ABSTRACT Objective: To evaluate the effect of erosive challenges on the tooth- restoration interface of deciduous teeth treated with different adhesive protocols. Material and Methods: Deciduous molars were cut mesiodistally, then embedded, abraded and polished (n=80). Samples were randomly divided according to the adhesive system used into: G1 (Adper Sing

8. Comparative study between laser and conventional techniques for class V cavity preparation in gamma-irradiated teeth (in vitro study)
Abstract Objective: The purpose of this study was to compare laser with conventional techniques in class V cavity preparation in gamma-irradiated teeth. Methods: Forty extracted human teeth with no carious lesions were used for this study and were divided into two main groups: Group I (n = 20) was not subjected to gamma radiation (control) and Group II (n=

9. Comparative in vitro evaluation of CAD/CAM vs conventional provisional crowns
ABSTRACT Objective This study compared the marginal gap, internal fit, fracture strength, and mode of fracture of CAD/CAM provisional crowns with that of direct provisional crowns. Material and Methods An upper right first premolar phantom tooth was prepared for full ceramic crown following tooth preparation guidelines. The materials tested were: VITA CA

10. Accuracy of intraoral and extraoral digital data acquisition for dental restorations
ABSTRACT The computer-aided design (CAD) and computer-aided manufacturing (CAM) process chain for dental restorations starts with taking an impression of the clinical situation. For this purpose, either extraoral digitization of gypsum models or intraoral digitization can be used. Despite the increasing use of dental digitizing systems, there are only few st

11. Influence of crosshead speed on failure load and failure mode of restored maxillary premolars
We analyzed the effect of the crosshead speed of an applied load on failure load and failure mode of restored human premolars. Fifty intact, noncarious human premolars were selected. Class II mesio-occlusodistal preparations were made with a water-cooled high-speed preparation machine, and the teeth were restored with composite resin. The specimens were divi

12. Canal transportation and centering ability of curved root canals prepared using rotary and reciprocating systems
Abstract Aim: To evaluate canal transportation and centering ability of Protaper and WaveOne systems in curved root canals by cone-beam computed tomography. Methods: Twenty human molars were randomly divided into two groups according to the system used: Group GP (ProTaper Universal(r)) and group GW (WaveOne(tm)). CT scans were performed before and after th
