Aim. Study aimed to determine effects of flowable composites as liner on marginal and internal voids in MOD composite restorations with dif ferent gingival levels. Methods. 45 molars were prepared for MOD cavities. Finish line was prepared 1 mm apical to mesial, and 1 mm coronal to the cemento-enamel junction on distal. Teeth were restored with: Solitaire; Solitaire + Revolution; Surefil; Suref...

UNLABELLED Secondary caries is still the main cause of restoration replacement, especially on the root surface. OBJECTIVE This in vitro study evaluated the cariostatic effects of fluoride-containing restorative materials associated with fluoride gels, on root dentin. MATERIALS AND METHODS A randomized complete block design was used to test the effects of the restorative systems, fluoride re...

OBJECTIVES The aim of this study was to investigate the effect of delayed finishing/polishing on the surface roughness, hardness and gloss of tooth-coloured restorative materials. METHODS Four different tooth-coloured restoratives: a flowable resin composite- Tetric Flow, a hybrid resin composite- Venus, a nanohybrid resin composite- Grandio, and a polyacid modified resin composite- Dyract Ex...

The aim of the laboratory study was to evaluate the degree of conversion (DC) and surface hardness of two nanofilled resin composite restorative materials compared to three other tooth-colored restorative materials. A light-emitting diode curing unit was used to photo-activate a hybrid composite (FiltekTM Z250), two nanofilled composites (Tetric® EvoCeram, FiltekTM Supreme XT), a nano-ionomer (...

Significance of Study Mineral trioxide aggregate (MTA) and Biodentine (calcium silicate-based materials) have great importance in dentistry. There is no study comparing the bond strength of Biodentine and MTA for composite, compomer, and compomer or resin-modified glass ionomer (RMGIC). Although many advantages of Biodentine over MTA; in this study, MTA has shown better shear bond strength (SBS...

Purpose. The objective of this study was to assess the impact beverages and tooth brushing on microhardness different restorative materials. Materials-methods. Disk-shaped samples compomer (Dyract XP), glass ionomer cement (GIC) (Ionofil Molar AC), composite resin (Filtek Z250) were prepared. randomly allocated four groups conditioned in various (cheery juice, cola, chocolate milk, distilled wa...

This study observed alteration in the radiopacity and microhardness of expired resin-based materials compared to non-expired materials and the operating characteristics of the X-ray source used. Five 2 mm-thick cured specimens were prepared for each material: composite resins (P60®, Z100®), and a compomer (Dyract AP®). Radiopacity of the specimens was evaluated comparing the density of the resi...

Tooth coloured adhesive restorative materials are widely accepted and used for the restoration of carious and non-carious cervical lesions. The aim of this study was to evaluate and compare the solubility and sorption values of compomer (Dyract ®), conventional glass-ionomer(Fuji II ) and resin modified glassionomer (Fuji II LC improved) cements in various beverages such as tea, coffee, coca-co...

The objective of this in vitro study was to evaluate demineralization around restorations. Class V preparations were made on the buccal and lingual surfaces of each tooth. TPH (Group 1), Fuji II LC (Group 2), Tetric (Group 3), Dyract (Group 4), GS 80 (Group 5) and Chelon Fil (Group 6) were randomly placed in equal numbers of teeth. The teeth were submitted to a pH-cycling model associated with ...

The objectives of this research were (1) to analyze the variations of the permeability of dentin after restoration with two polyacid-modified resin composites (Compoglass, Dyract) and four single-bottle adhesives (Prime & Bond 2.0, Syntac Single Component, OptiBond Solo, and Single Bond--Scotch Bond 1 in Europe--immediately (approximately 1 hour) after insertion. A perfusion system with distill...
