Patients suffering from acid reflux due to endogenous causes are often affected by gastroesophageal disease which, in the oral environment, lingual and palatal enamel erosion. As does not have intrinsic ability repair itself, application of alloplastic materials, such as toothpastes is suggestable. The aim this “in vitro” study was compare effectiveness two different preventing erosion disease....

Combinations of medicinal plants ensure the collective work several active components, which can lead to an additive or synergistic effect. We have chosen bur-marigold-calendula-hawthorn combination obtain antiallergic herbal medicine, in bur-marigold is main plant, calendula a helper plant that helps fight against accompanying symptoms, and hawthorn harmonizes action first 2 plants.

introduction: marginal seal integrity is important for a successful adhesive dental restoration. alterations caused by laser irradiation in the enamel and dentin surface can affect the marginal integrity of adhesive restorations. the aim of this study was to evaluate the microleakage of a composite resin restoration in primary teeth following laser irradiation of enamel and dentin. methods: for...

OBJECTIVE The aim was to evaluate the effect of different adhesive systems and surface treatments on the integrity of resin-resin and resin-tooth interfaces after partial removal of preexisting resin composites using quantitative image analysis for microleakage testing protocol. MATERIALS AND METHODS A total of 80 human molar teeth were restored with either of the resin composites (Filtek Z25...

OBJECTIVE To evaluate tensile bond strengths of 2 dentin bonding agents containing solvents on Nd:YAG and Er,Cr:YSGG laser-etched dentin surface. METHOD AND MATERIALS Occlusal enamel of 146 molars was removed, and exposed surfaces were ground with a diamond bur to produce bur-cut dentin surfaces. Of those teeth, 120 were assigned to 3 groups of 40 samples in which dentin was conditioned with ...

Background and aims. Er:YAG laser irradiation has been claimed to improve the adhesive properties of dentin; therefore, it has been proposed as an alternative to acid etching. The aim of this in vitro study was to investigate the shear bond strength of an etch-and-rinse adhesive system to dentin surfaces following Er:YAG laser and/or phosphoric acid etching. Materials and methods. The roots of ...

AIM To evaluate and compare the shear bond strength of metal brackets bonded to ceramic surfaces using different conditioning methods and to assess the site of bond failure after debonding. MATERIALS AND METHODS A total of 70 ceramic surfaces were produced with uniform shape, size and composition. The samples were divided into 7 groups (each of 10 samples). Group 1 was the control group (untr...

OBJECTIVES Adhesive systems are continuously being introduced to Dentistry, unfortunately often without sufficient clinical validation. The aim of this study was to evaluate the clinical performance of cervical restorations done with three different adhesive systems. MATERIAL AND METHODS 158 non-carious cervical lesions of 23 patients were restored with a nanofilled composite resin (Filtek Su...
