PURPOSE The purpose of this study was to evaluate and compare the effects of different surface pretreatment techniques on the surface roughness and shear bond strength of a new self-adhering flowable composite resin for use with lithium disilicate-reinforced CAD/CAM ceramic material. MATERIALS AND METHODS A total of one hundred thirty lithium disilicate CAD/CAM ceramic plates with dimensions ...

The aim of this study was to investigate the effects of surface conditioning protocols on the shear bond strength (SBS) of metal brackets to aged composite resin surfaces in vitro. Ninety composite resin discs, 6 mm in diameter and 2 mm in height, were prepared and treated with an ageing procedure. After ageing, the specimens were randomly assigned to one of the following groups: (1) control wi...

Objectives: The aim of this investigation was to assess the influence of different surface treatments and repair material on the repair shear bond strength (SBS) of GC Fuji IX GP Packable Posterior Restorative, Filtek Bulk Fill, and Filtek Supreme Ultra Flowable. Methods: Thirty cylindrical specimens were prepared from each material and randomly allocated into 3 groups/10 each. Group 1: no surf...

The purpose of the present study was to assess the bond strength of composite resin repairs subjected to different surface treatments and accelerated artificial aging. 192 cylindrical samples (CSs) were prepared and divided into 24 groups (n = 8). Half of the CSs were stored in water for 24 h, and the other half were subjected to C-UV accelerated aging for non-metallic specimens. The treatments...

in present research study, 44 canine teeth of with completely formed apex was selected in 11 cats. jaw bones were removed while teeth were kept intra alveolar sockets and routine root canal therapy was performed on each root. afterwards, 3mm of each root were cut apically. 20 teeth underwent cavity preparation via high speed dental turbine and round diamond bur, 20 via endosonic device and 4 (1...

to evaluate the different bonding strategies for repairing aged resin composite restorations. The review was reported according PRISMA Statement and registered in Open Science Framework (DOI:10.17605/OSF.IO/WZTGS). Two reviewers performed a literature search across Embase (758), Pubmed (1244), Scopus (4300), Cochrane library (128) Web of (2538) databases. risk bias assessed random sequence gene...

Abstract Tooth enamel machining is a common procedure in dental surgery, yet the cutting mechanisms and performance of different burs remain unclear. In field, this poses challenges for dentists selecting appropriate specific operations. engineering creates difficulties understanding tooth designing new high-performance burs. Therefore, objective study to bridge gap between medicine by comprehe...

BACKGROUND The objective of this study was to investigate the influence of Er,Cr:YSGG laser irradiated at different powers on the micromorphology and the bonding property of non-carious sclerotic dentin to resin composites. METHODS Two hundred bovine incisors characterized by non-carious sclerotic dentin were selected, and the seventy-two teeth of which for surface morphological analysis were...

BACKGROUND The only approach used in the refractory lesions of stable vitiligo is the surgical supply of melanocytes. Suction Blistering Epidermal Graft is one of the most common and effective techniques. There are multiple modalities, including the motor-driven diamond fraise, for the preparation of recipient sites in suction blistering epidermal graft with different repigmentation rates and c...
