• Abstract

  This study will evaluate the importance of chronic stress (EC) in stimulation of the sympathetic nervous system and explore the pathogenic mechanisms underlying periapical lesions. Animal model of chronic stress and periapical lesion as well as cultured human fibroblasts will be used. The expression of tyrosine hydroxylase, the ±1-adrenergic (±1-AR) and ²2-adrenergic (²2-AR) receptors wil…

• Abstract

  The present study will evaluate the levels of lipoteichoic acid (LTA ), endotoxins and microorganisms in root canals with pulp necrosis and radiographically visible periapical lesion during treatment with endodontic instrumentation mechanized and 2.5% sodium hypochlorite. In addition, there will be a correlation between the amount of LTA, endotoxins, microbial organisms, periapical lesion…

• Abstract

  Regenerative cements make up a fundamental part of the current endodontics, due to its importance in the cases of apicification, apicigenesis, pulpotomy, revascularization and others, and the mineral trioxide aggregate is the most used. The objective of this study was to evaluate the cytotoxicity and genotoxicity of the "Angelus" MTA, MTA Repair HP, five "5MO" mineral oxides and the "Ca (…

• Abstract

  Internal Root Resorption (IRR) leads to structural weakening of the teeth. There are still questionable points in the use of fiberglass post in the restoration of endodontically compromised teeth with great loss of root structure. As a proposal, this study intends to: analyze the thickness of resin cement in the cementation of fiberglass post Reforpost® (Angelus) and Rebilda Post GT® (VOC…

• Abstract

  Objective: To evaluate the antimicrobial action of passive ultrasonic irrigation (PUI) or conventional irrigation (CI) of NaCl 2.5% and 17% EDTA or QMiX after biomechanical preparation on the viability of mixed biofilms and neutralization of endotoxins in root canals ex vivo. Material and Methods: Ninety-six unirradicular human roots with single and straight canal will be selected and inf…
