1. Effect of peracetic acid used as single irrigant on the smear layer, adhesion, and penetrability of AH Plus
Abstract The aim of this study was to evaluate the effect of peracetic acid (PAA) as a single irrigant on the smear layer, on the intraradicular dentinal bond strength, and on the penetrability of an epoxy-based resin sealer into the dentinal tubules. A total of 120 roots were distributed into 4 groups according to the irrigant used in root canal preparation

2. Avaliação do uso de argilas montmorilonitas modificadas na adsorção de nitrato em meio aquoso
RESUMO Este estudo investigou a eficiência da remoção de nitrato em meio aquoso usando adsorção em argilas montmorilonitas comerciais, comparativamente a uma resina aniônica comumente usada nessa operação. Algumas dessas argilas foram intercaladas como o íon hexadeciltrimetilamônio para avaliação. Áreas superficiais específicas, capacidades de

3. Influência de tratamento dentinário com EDTA sobre a resistência de união de sistemas adesivos autocondicionantes
Resumo Introdução Os adesivos autocondicionantes apresentam técnica adesiva simplificada e diminuição na sensibilidade pós-operatória. Quando aplicados sobre a dentina, atuam sobre a smear layer, cuja efetiva remoção ainda constitui um desafio. Uma substância utilizada como pré-tratamento dentinário na ajuda da remoção da smear layer é o eti

4. Iodoform Vs Calcium Hydroxide/Zinc Oxide based pastes: 12-month findings of a Randomized Controlled Trial
Abstract This study evaluated clinical and radiographic twelve-month outcomes of root canal treatments (CT) with smear layer removal, performed in primary teeth, using two different root canal filling materials. Pulpectomy was performed on 27 primary teeth with necrosis or irreversible pulpitis, caused by dental caries or trauma, in 23 children (2-7 years ol

5. Efficacy of sonic and ultrasonic irrigation devices in the removal of debris from canal irregularities in artificial root canals
Abstract Objective To evaluate the efficacy of different sonic and ultrasonic devices in the elimination of debris from canal irregularities in artificial root canals. Materials and Methods A resin model of a transparent radicular canal filled with dentin debris was used. Five groups were tested, namely: Group 1 – ultrasonic insert 15.02; Group 2 – ult

6. The effect of hydrofluoric acid and resin cement formulation on the bond strength to lithium disilicate ceramic
Abstract To investigate how the hydrofluoric acid (HF) concentrations applied to a lithium disilicate glass-ceramic (EMX) affects the surface morphology and microtensile bond strength (μTBS) of ceramics to dentin, using light-cured resin cements with or without UDMA. Sixty-three EMX square ceramic blocks were etched for 20 seconds using different HF concent

7. Doxycycline-containing glass ionomer cement for arresting residual caries: an in vitro study and a pilot trial
Abstract In a previous study, we demonstrated that the incorporation of doxycycline hyclate (DOX) into resin-modified glass ionomer cement (RMGIC) inhibited important cariogenic microorganisms, without modifying its biological and mechanical characteristics. In this study, we keep focused on the effect of that experimental material as a potential therapy for

8. Can intra-radicular cleaning protocols increase the retention of fiberglass posts? A systematic review
Abstract The presence of residues within the root canal after post-space preparation can influence the bond strength between resin cement and root dentin when using fiberglass posts (FGPs). Currently, there is no consensus in the literature regarding what is the best solution for the removal of debris after post-space preparation. This systematic review invo

9. Green polyurethane synthesis by emulsion technique: a magnetic composite for oil spill removal
Abstract After the consolidation of the Brazilian biodiesel industry, issues related to the final destination of the glycerin, the by-product from the biodiesel industrial process, drawing the attention of several researchers. There are several uses to this byproduct. Among them, the obtaining of polymers, such as polyurethane (PU), are very encouraged since

10. Should my composite restorations last forever? Why are they failing?
Abstract Composites resins have become the first choice for direct anterior and posterior restorations. The great popularity is related to their esthetic appearance and reduced need of sound tissue removal as compared with former treatments. Several studies have demonstrated that composite restorations may last long in clinical service. In this review we dis

12. Influence of solvents on the bond strength of resin sealer to intraradicular dentin after retreatment
Abstract This study evaluated the removal of filling material with ProTaper Universal Rotary Retreatment system (PTR) combined with solvents and the influence of solvents on the bond strength (PBS) of sealer to intraradicular dentin after canal reobturation. Roots were endodontically treated and distributed to five groups (n = 12). The control group was not
