Evaluation of Microleakage at the Junction Between Combined Amalgam/Composite Resin Restorations Using Different Bonding Systems in Class II Cavities

Abstract Objective: To evaluate the microleakage at the junction between amalgam-composite resin restorations using different bonding systems. Material and Methods: In this in-vitro study, standard class II cavities were prepared on 40 human maxillary premolars. The axial and gingival floor depths of t...

Effect of implant crestal position on primary stability before and after loading: an in vitro study

Introduction: Primary stability is one of the goals of modern implant dentistry and if achieved, reduces treatment time for prosthetic rehabilitation and the number of interventions made in patients mouth. Several companies state as protocol for connical conection implants, a subcrestally positioning. O...

O método de fotopolimerização é capaz de influenciar nos valores de microdureza das resinas compostas? Um estudo in vitro

Introdução: a inovação dos métodos de fotopolimerização foi proposta na tentativa de diminuir o estresse de contração de polimerização das resinas compostas e proporcionar maior conforto ao paciente, reduzindo o tempo de atendimento odontológico. Objetivo: avaliar a microdureza de duas resina...

In vitro and in silico evaluation of the schistosomicidal activity of eugenol derivatives using biochemical, molecular, and morphological tools

Background Eugenol shows both antibacterial and antiparasitic activities, suggesting that it might be evaluated as an option for the treatment of praziquantel-resistant schistosome. Methods The in vitro activities of three eugenol derivatives (FB1, FB4 and FB9) on adult worms from Schistosoma mansoni we...

Influence of customization and light-curing device on the bond strength of glass fiber posts - in vitro study

Introduction: Endodontically treated teeth are usually affected by extensive structure loss requiring the use of intraradicular posts to provide retention and restoration. Objective: An in vitro assessment was performed on the bonding of glass fiber posts to the root dentin. Material and method: Ninety...

Cariogenic and erosive potential of pediatric medicines and vitamin supplements

Introduction: Pharmaceutical pediatric formulations with low in pH and high in total titratable acidicity used frequently and over long periods of time, have the potential to produce erosive lesions in teeth. On the other hand, high concentration of sucrose, the nocturnal use and the lack of hygiene afte...

In Vitro and In Vivo evaluation of montmorillonite for paraquat poisoning

Abstract Evaluation of montmorillonite for paraquat by in vitro and in vivo test. In vitro test were evaluated by a batch test, taking the paraquat concentration, adsorbents, reaction environment and time as indices, the absorption rate was screened by orthogonal design. In vivo test was executed with r...

Hydroxymethylnitrofurazone (NFOH) decreases parasitaemia, parasitism and tissue lesion caused by infection with the Bolivia Trypanosoma cruzi type I strain in Swiss and C57BL/6 mice

Abstract The chemical hydroxymethylation of the antimicrobial nitrofurazone leads to the prodrug NFOH, also increases the anti-T. cruzi activities (in vitro and in vivo), as well as showed non-genotoxic (Ames and micronucleus assays). In the present study, we assessed the anti-T. cruzi effect of the NFOH...

Anticholinesterase activity of β-carboline-1, 3, 5-triazine hybrids

Abstract The β-carboline-1,3,5-triazine hydrochlorides 8-13 were evaluated in vitro against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). The analysed compounds were selective to BuChE, with IC50 values in the range from 1.0-18.8 µM being obtained. The N-{2-[(4,6-dihydrazinyl-1,3,5-tr...

Development of diethylcarbamazine-loaded poly(caprolactone) nanoparticles for anti-inflammatory purpose: Preparation and characterization

Abstract Diethylcarbamazine-loaded nanoparticles were previously evaluated for their anti-inflammatory activity. However, little is known regarding their physicochemical properties. Thus, the purpose of this study was to physiochemically characterize diethylcarbamazine-loaded poly(caprolactone) nanoparti...
