AIM This study aimed to evaluate the microleakage of Class V restorations filled with a 7th-generation self-adhesive composite. MATERIALS AND METHODS In 40 permanent premolars and 80 primary canines, 160 Class V cavities were prepared, which were filled with four restorative materials (n of each material=20 permanent and 20 primary restorations): control: nonbonded composite (Heliomolar), GI:...

OBJECTIVE This in vitro study aimed to evaluate the influence of different surface treatments, 3 luting agents and thermocycling on microtensile bond strength (µTBS) to zirconia ceramic. MATERIAL AND METHODS A total of 18 blocks (5x5x4 mm) were fabricated from zirconia ceramic (ICE Zirkonia) and duplicated into composite blocks (Alphadent). Ceramic blocks were divided into 3 groups (n=6) acco...

Objective: To compare the cytotoxicity level of a new calcium silicate-based resin cement (TheraCem) with two commonly used cements, including conventional self-adhesive (Panavia SA) and resinmodified glass ionomer (FujiCem2), on human gingival fibroblast cells after 24 48 hours. Material Methods: Twelve discs each type were fabricated. The extract disks was made by incubating them in cell medi...

Background and Purpose: The aim of this study was to evaluate the flexural strength values five luting cements that are commonly used in dental restorations after exposed hyperbaric pressure.
 Methods: Five (polycarboxylate cement, glass ionomer manual-mixed resin two auto-mixed cement) were prepared. (25 x 2 mm3) (n=16 for each) specimens divided into subgroups (n=8) pressure (3 ATM) 20 t...

Objectives: To analyze the ion exchange between conventional glass-ionomer restorative material, (Fuji IXGC Co., Japan) and tooth components in primary molars after long periods of function in vivo. Methods: Five deciduous mandibular molars were collected after normal exfoliation. An intact deciduous molar served as control, a second deciduous molar was restored occlusaly with Fuji IX in vitro,...

OBJECTIVE This in vitro study evaluated the microleakage of a nano-filled resin-modified glass ionomer and a high viscosity glass-ionomer restorations in class V cavities. MATERIALS AND METHODS Thirty-two class V cavities prepared on the buccal and lingual surfaces of 16 sound, third molar teeth were randomly assigned into two groups and restored by one of the glass ionomer material; Group A:...
