Objective: This study aimed to evaluate the suitability of one specific silorane-based composite for the application as a repair material for different substrates. Materials and methods: Truncated cones of composites fabricated and thermocycled for 6000 cycles to serve as a substrate were made of two commercially available dimethacrylate-based composites (DBC) (Filtek Supreme and Clearfil APX) ...

Introduction: This in vitro study aimed to evaluate the effect of different monomer systems on microleakage in class II composite open sandwich restorations with and without a separating agent placed between the nanofilled resin modified glass ionomer and the resin. Materials and methods: Class II cavity preparations were prepared in maxillary premolars (n = 240) and the cervical limit of the p...

Aim: To evaluate invitro the effect of post obturation materials on reinforcement of peri-cervical dentin (PCD) Materials and Method : Sixty extracted, maxillary premolar teeth were selected.After preparation of standardized access, crowns were resected so that a final dimension of 4 mm from one mm below highest point of proximal cervical line was achieved. Then, the enamel was carefully remove...

OBJECTIVES To assess the effect of lactic acid (LA) on microleakage of silorane-based composite restorations and methacrylate-based composites with self-etch and etch-and-rinse bonding systems. MATERIALS AND METHODS Class V cavities were prepared in 120 extracted human teeth, divided into four groups and restored as follows: 1. Silorane-based composite+P90 adhesive system (P90); 2. Filtek Z25...

SUMMERY: Polymerization shrinkage and related adverse effects are still considered a major problem of dental composites. To solve this problem different approaches are offered. Currently, 3M ESPE developed a new monomer system based on cationic ring opening, the goal is to create a composite material with low polymerization shrinêage called siloran. Aim: To investigate the clinical presentation...

OBJECTIVE The purpose of this study was to reveal the effectiveness of non-thermal atmospheric plasma brush in surface wettability and modification of four dental substrates. METHODS Specimens of dental substrates including dentin, enamel, and two composites Filtek Z250, Filtek LS Silorane were prepared (∼2mm thick, ∼10mm diameter). The prepared surfaces were treated for 5-45s with a non-ther...

OBJECTIVES Tricalcium silicate is the major constituent phase in mineral trioxide aggregate (MTA). It is thus postulated that pure tricalcium silicate can replace the Portland cement component of MTA. The aim of this study was to evaluate bond strength of methacrylate-based (MB) composites, silorane-based (SB) composites, and glass ionomer cement (GIC) to Biodentine® and mineral trioxide aggreg...

BACKGROUND The authors conducted a study to evaluate esthetic restorative materials' color differences after setting and color matching between set materials and a shade guide. MATERIALS AND METHODS The authors evaluated 13 resin-based composites, one silorane-based composite, two polyacid-modified resin composites and one conventional glass ionomer cement. They measured the color parameters ...

OBJECTIVE The aim of this in vitro study was to evaluate the microtensile bond strength (µTBS) to dentin of two different restorative systems: silorane-based (P90), and methacrylate-based (P60), using two cavity models. MATERIAL AND METHODS Occlusal enamel of 40 human third molars was removed to expose flat dentin surface. Class I cavities with 4 mm mesial-distal width, 3 mm buccal-lingual wi...
