1. 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

2. Tissue dissolution and modifications in dentin composition by different sodium hypochlorite concentrations
ABSTRACT Sodium hypochlorite (NaOCl) remains the most used irrigation solution during root canal preparation because of characteristics such as wide-spectrum antimicrobial activity and organic tissue dissolution capacity. However, these solutions can alter dentin composition and there is no consensus on the optimal concentration of NaOCl to be used. Objecti

4. 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

5. Impact of chemical agents for surface treatments on microhardness and flexural strength of root dentin
This study assessed the cross-sectional Knoop microhardness and flexural strength of root dentin exposed to different surface treatments with chemical agents after biomechanical preparation. Root canals from human canines were biomechanically treated and divided into eight groups (n=10) to receive one of the following dentin treatments: I. Deionized water (c

7. ESTUDO DAS PROPRIEDADES QUÍMICAS E ANTIMICROBIANAS DAS SOLUÇÕES DE HIPOCLORITO DE SÓDIO / STUDY OF CHEMICAL AND ANTIMICROBIAL PROPERTIES OF SODIUM HYPOCHLORITE SOLUTIONS
The objective of this study was to evaluate the dissolution of bovine pulp tissue by NaOCl solutions in different concentrations for a similar period to the time of root canal preparation, and chemical and antimicrobial properties of the resulting solution after this dissolution. Fragments of bovine dental pulp were exposed to different solutions (0.5, 1.0,

9. Desenvolvimento e validação de método analítico para quantificação de ácido pfáffico em Hebanthe eriantha / Development and validation of analytical method for quantification of pfáffico acid in Hebanthe eriantha
Hebanthe erianthe (Amaranthaceae) is known as "Brazilian ginseng¿, due to the similarity of its roots with those of Panax ginseng (Araliaceae), the "Korean ginseng¿. Its roots, with proved antineoplastic activity, are constituted by saponins, which during hydrolysis, release saccharides and free molecules of pfaffic acid, a nortriterpene. Pfaffic
