The purpose of this study was to evaluate the residual antibacterial activity of several calcium hydroxide [Ca(OH)2]-based pastes, placed in root canals of dogs' teeth with induced chronic periapical lesions. Root canals were instrumented with the ProFile rotary system and filled with 4 pastes: G1 (n=16): Ca(OH)2 paste + anesthetic solution; G2 (n=20): Calen paste + camphorated p-monochlorophen...

OBJECTIVES: This in situ/ex vivo study aimed to analyse the impact of possible MMPinhibitors (chlorhexidine and green tea extract) on dentin wear induced by erosion or erosion plus abrasion. METHODS: Twelve volunteers took part in this cross-over and double-blind study performed in 4 phases of each 5 days. Bovine dentin samples were worn in palatal appliances and subjected to extraoral erosion ...

AIM This study investigated the effectiveness of disinfecting solution when incorporated into alginate powder instead of water against some microorganisms and on compressive strength of alginate. MATERIALS AND METHODS For measuring antimicrobial activity of alginate, 60 alginate specimens were prepared and divided into two groups: One with water incorporated in the mix (control) and the other...

Aim & Objectives: The aim of this prospective pilot-study was to assess the efficacy of intra alveolar application of 1% chlorhexidine gel (CHX) on the reduction of dry socket (DS) occurrence following surgical extraction of mandibular third molars. Materials and Methods: A randomized split-mouth-design study included twenty-five patients with bilaterally impacted lower third molars (partial or...

Guedes-Pinto paste is the filling material most employed in Brazil for endodontic treatment of deciduous teeth; however, the Rifocort® ointment has been removed. Thus, the aim of this study was to investigate the antimicrobial potential of filling pastes, by proposing three new pharmacological associations to replace Rifocort® ointment with drugs of already established antimicrobial power: Neba...

(1) The objective of the study is to conduct a comprehensive systematic review in vitro studies order assess depth which E. faecalis bacteria penetrate human dentinal tubules after use various irrigation solutions. (2) Methods: A literature search MEDLINE, Scopus, Cochrane CENTRAL, and Embase databases was conducted, as well backward forward citation search. Two independent reviewers then selec...

AIM To assess the influence of dentin substrate and chlorhexidine on the marginal seal of composite resin restorations. MATERIALS AND METHODS The sample comprised 20 third molars. Four cavities were drilled in the dentin sur face, followed by sealing and restoration of sound dentin (n = 10) or carious dentin (n = 10). In the control group, cavities were immediately restored as follows: G1: on...
