Introdução: Os diastemas podem ser definidos como espaços entre os dentes ou ausência de contato entre dois ou mais dentes consecutivos, podendo acometer a arcada superior ou a inferior. As opções para o fechamento dos diastemas vão desde o tratamento ortodôntico até a utilização de laminados cerâmicos. Objetivos: O presente trabalho tem como objet...

In the actual times, with so many rehabilitation techniques and endodontic posts in the market, there are many doubts about which one is the best, the most cost-effective, the one that has more resistance among other questions. This work aimed to compare the intraradicular restorative treatments that involve the use of prefabricated posts and posts...

Background/Aims Traumatic dental injuries are highly prevalent and are considered an important health problem. The aim of this study was to evaluate the in vitro stress distribution around simulated traumatized teeth subjected to different types of splints by photoelastic analysis. Materials and Methods For each group, five models of maxillary and...

Objetivo: Este trabalho teve como objetivo relatar um caso de reabilitação estética através de laminados cerâmicos e cirurgia periodontal como forma de tratamento para a agenesia do elemento dental 22 e sorriso gengival associado à retração labial. Relato do Caso: Paciente, gênero feminino procurou a Clínica Multidisciplinar da Unipar (Sede/Umuaram...

The aim of this study was to analyze the effects of MTA on the structure and enzymatic activity of sPLA2 in order to provide subsidies for improvement in the formulation of the product. MTA powder was incubated for 60 min in the presence of sPLA2 and was analyzed by chromatography, electrospray mass (ESI-MS) and small-angle X-ray scattering (SAXS)....

A busca permanente pela estética tem levado muitos pacientes ao consultório odontológico com a intenção de obterem sorrisos mais harmônicos em relação à forma, tamanho, posicionamento e cor dos dentes. O clareamento de dentes vitais é uma alternativa conservadora, não invasiva quando comparado à microabrasão, facetas e coroas, além de proporcionar...

Aim: The aim of this study was to evaluate and compare the setting times (ST), flow (FW), radiopacity (RP), dimensional stability (DS), solubility (SB), and polymerization stress (PS) of the MTA Fillapex and AH Plus root canal sealers. Methods: The above qualities were tested according to ISO 6876/2001 standardization. The water used in the dimensi...

Less traumatic alternative methods for removal of decayed tissue has been developed. A non-invasive technique, which consists of applying a proteolytic substance that softens the infected dentin tissue and preserves healthy tooth tissue was released in the market. Thus, this work intended to describe a clinical case of caries removal using BRIX 300...

O objetivo deste estudo foi avaliar o efeito do antioxidante resveratrol associado ao peróxido de hidrogênio a 38%. 80 terceiros molares foram divididos em 8 grupos (n10): SC – Sem clareamento em 24h, SC21 – sem clareamento em 21 dias, SCR – Sem clareamento e com resveratrol em 24h, SCR21 – Sem clareamento e com resveratrol em 21dias, C – com clare...

Com advento das resinas compostas de segunda geração que apresentam características mecânicas e estéticas superiores às das resinas convencionais, principalmente com relação a resistência à abrasão, surge a possibilidade de utilizá-las associadas a fibras, como o sistema da Ivoclar Targis/Vectris. O objetivo deste trabalho foi apresentar a confecçã...

The interference of eugenol on the adhesive systems and composite polymerization could promote a higher marginal microleakage. This could be reduced by mechanical and chemical cleansing. The objective of this study was to evaluate the influence of the previous use of eugenol-based materials to a permanent restoration on the marginal microleakage. T...

When introduced to the market, silorane-based materials promised less contraction compared to other materials. The purpose of this study was to evaluate the contraction stress, flexural strength, and elastic modulus of the Filtek Silorane composite with different photoactivation protocols. Filtek Silorane and Filtek Z350 composites were inserted in...

Objectives: The aim of this study was to assess the effects direct or indirect water exposure on the 3 months hydrolytic degradation of three dentin bonding agents. Materials and Methods: The samples were divided in three groups: Clearfil SE Bond, Clearfil S3, Adper Singlebond 2; and the samples were restored with Filtek Z350. Subsequent to the res...

International Journal of Paediatric Dentistry 2012; 22: 435–441 Background. Hydrophilic adhesives may be used as pit and fissure sealants (sealants), but there is concern about the ability of self-etching adhesives to bond sealants to enamel. Aim. To study the bond strength (BS) and morphology of adhesive systems used as sealants. Design. OptiBond...

This study analyzed the bond strength (BS) of HEMA versus HEMA-free self-etch adhesive systems to dentin. The occlusal surface of 20 third molars was removed and the dentin was abraded with 600-grit silicon carbide paper. The teeth were randomly assigned to 4 groups (n = 5) and restored with GO, Adper SE Plus, OptiBond All-In-One, and Clearfil 3S B...

PURPOSE: Saliva contains both specific and non-specific protective factors of the immune system, such as antimicrobial proteins, which can inhibit the adhesion and viability of cariogenic microorganisms.
