INTRODUCTION The aim of the study was to evaluate the radiopacity, solubility, flow, film thickness, setting time, and adaptation to the root canal walls of 3 epoxy resin-based sealers: AH Plus, Acroseal, and Adseal. METHODS Physical tests were performed following American National Standards Institute/American Dental Association's requirements. For(More)
The aim of this study was to investigate whether variation in pH of sodium hypochlorite (NaOCl) increased its antibacterial and dissolution ability on polymicrobial biofilms formed in situ. Fifty-six dentin blocks (eight/group) were intraorally infected for 48 h and incubated in BHI for 48 h to standardize the biofilm growth. The specimens were irrigated(More)
Time-domain nuclear magnetic resonance (TD-NMR) is one of the most popular solutions for quality control in the food industry. Despite the recognized success of TD-NMR in quality control and quality assurance, the speed by which samples can be characterized by TD-NMR techniques is still a concern, primarily when considering online or high-throughput(More)
OBJECTIVES To determine the organic matter dissolution and changes in dentin chemical composition promoted by different concentrations of NaOCl over time. MATERIAL AND METHODS Fragments of bovine muscle tissue were weighed before and after 5, 10, and 15 min of immersion in the groups (n=10): G1- 0.9% saline solution; G2- 1% NaOCl; G3- 2.5% NaOCl; and G4-(More)
OBJECTIVES To compare three methods of intratubular contamination that simulate endodontic infections using confocal laser scanning microscopy (CLSM). MATERIAL AND METHODS Two pre-existing models of dentinal contamination were used to induce intratubular infection (groups A and B). These methods were modified in an attempt to improve the model (group C).(More)
An experiment was carried out in order to evaluate the effects of water levels in soil on seedlings formation papaya tree from group Soil and Formosa. The treatments were distributed in delineation completely randomized using the factorial design 5x2 (60, 70, 80,90 and 100% field capacity of the soil and two genotypes of papaya Soil and Formosa group). The(More)
The irrigation of the root canal system contributes effectively to appropriate cleanness and antisepsis, thus rendering endodontic treatment more successful. An ideal irrigation protocol was suggested in order to overcome the limitations of commonly used irrigants, in addition to enhancing antisepsis. This protocol recommends the use of sodium hypochlorite(More)

Objective: This in vitro study evaluated the efficiency of EDTA, apple vinegar and SmearClear, with and without ultrasonic activation, on smear layer removal. Methods: Seventy extracted canines were randomly divided into eight groups and prepared by using ProTaper instruments. The final irrigation regimens used were: Group 1 (control) (SAL) and Group 2(More)
Currently, there are several issues that deserve attention in the area of oral health promotion, such as dental caries, oral health programs and oral cancer. These issues were discussed during the 18th Congress of the Brazilian Association for Oral Health Promotion (Associação Brasileira de Odontologia de Promoção de Saúde ABOPREV), held April 11 to 13,(More)
