BACKGROUND The aim of this study was to evaluate the effect of a desensitizing agent on microleakage of Class V cavities. MATERIAL AND METHODS 72 premolar teeth were used. There were 6 groups. Class V restorations were prepared with two different restorative materials (Equia fil, GC, America and Grandio, VOCO, Germany) and two adhesive systems (Clearfil SE Bond, Kuraray, Japan and S3 Bond Plu...
Odontoblasts play an important role in the transduction of the sensory signals underlying dentinal pain. Transmembrane voltage-independent Ca(2+) influx in odontoblasts has been well described. Voltage-dependent Ca(2+) influx has also been reported, but its biophysical properties remain unclear. The aim of the present study was to investigate the desensitizing effect of voltage-dependent Ca(2+)...
Purpose: Routine tooth polishing continues to be an integral part of clinical practice even though the concept of selective polishing was introduced in the 1980s. This procedure assists in the removal of stains and plaque biofilm and provides a method for applying various medicaments to the teeth, such as desensitizing agents. Use of traditional polishing methods, i.e. a rubber–cup with prophyl...
To evaluate the effect of a dentin adhesive on sclerotic dentin, contraction gap width and shear bond strength were measured. Dentin cavity wall was pretreated with an experimental dentin bonding system with and without a dentin primer, or with a commercial dentin bonding system. In the experimental dentin bonding groups, contraction gap width of sclerotic dentin was significantly smaller than ...
The aim of this study was to evaluate the microtensile bond strength (microTBS) and the elemental contents of the adhesive interface created to normal versus caries-affected dentin. Extracted human molars with coronal carious lesions were used in this study. A self-etching primer/adhesive system (Clearfil Protect Bond) was applied to flat dentin surfaces with normal and caries-affected dentin a...
AIM This randomized, double blind, split mouth study was aimed to compare three dentin desensitizing treatment modalities. METHODS Two hundred sixty teeth of 25 patients; each having at least 2 hypersensitive teeth in each quadrant, were included. Teeth were randomized to 4 groups: Group A treated with 2% NaF solution, Group B received GLUMA®; an aqueous solution of Hydroxy-Ethyl-Methacrylate...
The relation between the bonding efficacy of the dentin adhesive and the physical change of the dentin after treatment with various dentin cleansers was investigated. The dentin surface was cleaned with one of the seven experimental dentin cleansers, 5, 10, 20, 30 and 40% of the phosphoric acid, neutralized 0.5 M EDTA solution (pH 7.4) and 9.1% pyruvic acid containing 9.1% glycine, prior to the...
