OBJECTIVE The clinical suitability of low-shrinkage resin composites for class V cavities has not been investigated in vivo. The purpose of this double-blind randomized clinical trial was to compare the clinical performances of low-shrinkage resin composite Filtek silorane and nanoceramic resin composite Ceram X mono in non-carious cervical lesions (NCCLs)(More)
PURPOSE To evaluate the 2-year clinical performance of an ormocer, a new nanofill composite and as a control a conventional hybrid composite restorations in small Class I cavities of permanent molars. METHODS 90 Class I maxillary cavities were prepared in 90 patients. Cavities were restored incrementally in oblique layers with ormocer (Admira), nanofill(More)
PURPOSE To compare the 2-year clinical performance of a silorane-based resin composite with that of an established nanoceramic resin composite for class 1 posterior restorations. METHODS In this randomized controlled study, 100 class 1 molar cavities were prepared in 50 subjects. Each subject received a restoration with Filtek Silorane and Ceram.X Duo in(More)
The aim of this in vitro study was to compare the microleakage of repaired class V resin composite restorations prepared either by Er:YAG laser or a diamond bur. Ninety-six intact human molar teeth were randomly distributed into eight groups. In the first four groups, class V cavities (3 × 3 × 3 mm) prepared on the buccal and lingual surfaces of the teeth(More)
PURPOSE The aim of this clinical follow-up study was to determine the clinical performance of ormocer and a new nanofill composite material, lined or not lined with flowable composites, after 2 years. MATERIALS AND METHODS Occlusal restorations (n = 108) were placed in 54 patients with two symmetric restorations per patient. In one of the two restorations(More)
AIM Light-emitting diode light curing units (LED LCUs) have become more popular than halogen LCUs in routine dental restorative treatment. The aim of the study was to compare the effects of two conventional halogen (Hilux Plus and VIP) and two LED (Elipar FreeLight 2 and Smart Lite) light curing units on the depth of cure and the microhardness of various(More)
OBJECTIVE The effects of sonic and ultrasonic scalings (USSs) on the surface roughness of nanohybrid, flowable, and polyacid-modified resin composites and conventional glass ionomer cement were examined, and the effectiveness of repolishing on the scaled material surfaces was determined. MATERIALS AND METHODS The surface roughness of each sample was(More)
