immediate restoration after vital pulp therapy is essential in order to create and maintain effective coronal seal.the aim of this study was to evaluate the shear bond strength of recently used pulp capping materials: white mineral trioxide aggregate (mta), and calcium enriched mixture cement (cem) to composite resin with the use of etch-and-rinse and self-etch adhesive systems and compare them...

This study aimed to compare in vitro the shear bond strength between metallic brackets (Abzil) with conventional mesh bases and metallic brackets with bases industrially sandblasted with aluminum oxide using three adhesive systems, in order to assess the influence of sandblasting on adhesiveness and to compare 3 different bonding systems. Two hundred and forty bovine incisors were used and rand...

OBJECTIVE To evaluate, in vitro, the shear bond strength of self-curing (ConciseTM - 3M and Alpha Plast - DFL) and light-curing composites (TransbondTM XT - 3M and Natural Ortho - DFL) used in orthodontics bonding, associated to Morelli metal brackets, with further analysis of adhesive remnant index (ARI) and enamel condition in scanning electron microscopy (SEM). METHODS Forty human premolar...

Background: The purpose of this study was to evaluate the effect in vitro long-term simulation oral conditions on bond strength PEEK CAD/CAM lingual retainers. Material and methods: sample consisted 12 retainers each composed 2 centrally perforated 3x4mm pads joined by a connector. They were treated 98% sulfuric acid for 1 minute then conditioned with Single Bond Universal bonded surface premol...

Aim: The aim of this study was to investigate the effect of ozone used as cavity disinfectant on dentin bond strength of resin-based restorative material. Material and Method: The study included 36 adult 3rd molar teeth removed for surgical reasons. Each tooth was set in a cylindrical mould 2cm in diameter and 3cm high with the dentin surface parallel to the occlusal level and the roots remaini...

The aim of this study was to investigate whether the artificial aging by thermal cycling had influenced the marginal adaptation of class V restorations with/without chlorhexidine application in the bond process. Twelve intact human third molars were used. Class V cavity preparations were performed on the buccal surface and the teeth received 35% phosphoric acid-etching procedure (Ultradent Prod...

Er-YAG laser irradiation has been claimed to improve the adhesive properties of dentin. We tested the hypothesis that dentin adhesion is affected by Er-YAG laser conditioning. Superficial or deep dentin from human molars was: (a) acid-etched with 35% H3PO4; (b) irradiated with an Er-YAG laser (KaVo) at 2 Hz and 180 mJ, with water-cooling; and (c) laser- and acid-etched. Single Bond (3M ESPE) an...

AIM The aim of this study was to evaluate the effect of chlorhexidine and ethanol application on the push-out bond strength and bond durability of fiber posts cemented with an etch-and-rinse adhesive system/resin cement to intraradicular dentin. MATERIALS AND METHODS Fifty-four bovine roots were shaped for the cementation of a fiberglass post and received the application of 37% phosphoric aci...

BACKGROUND To evaluate, in vitro, the potential cytotoxicity of three different dental adhesives systems (Adper Single Bond 2 -SB, Silorane System Adhesive Bond -SSAB and Single Bond Universal -SBU) on cultivated Vero cells after different contact times. MATERIAL AND METHODS The cells were cultured in a concentration of 2 x 105 cells/mL for 24h and grown to sub-confluent monolayers. VERO cell...
