Adhesive Systems in Prevention of Dental Caries

Imperfect treatment of lost dental tissue can easily lead to its other destruction and dental sensitivity. Today, we have a possibility to treat and fill lost dental crown with adhesive technique and filling composite resins. Authors try in the report to evaluate adhesive systems of Vth and VIth Generation from a view of achieving optimal hermetical sealing of prepared tissue and perfect aesthetical filling in dental cervical region as a recurrent caries formation prevention. In the study we evaluated adhesive systems type total-etch (Vth generation) and self-etch (Vith generation) according to ISO/TS 11405.2003 E. The study confirms that present dentinal adhesives when exact indications and directions for use are followed, create optimal hermetic sealing of dentinal tubules in prepared or in other way destroyed dental tissue. The created hybrid layer enables to build up plastic filling with excellent marginal sealing. It also prevents bacterial percolation to such treated tissue and prevents recurrent caries formation

Attrition, Abrasion, Corrosion and Abfraction New Overview of Superficial Teeth Lesions

The authors present actualized and revised nomenclature and classification for surface teeth lesions. Their objective is the standardization, clarity and aplicability for stomatologists.. The paper describes pathodynamic mechanism in originating surface lesions of teeth. Understanding the pathodynamic mechanism of the origin lesions or their combinations make it possible for the dentist to establish a precise diagnosis and to provide adequate suitable therapy

Comparison of Reliability of Vth and VIth Generation Adhesive Systeme by Thermocycling

The target of the thestudy was to compare the reliability of adhesive systems of Vth. and VIth generation by thermocycling according to method ISO/TS 11405:2003 (E). For comparison there were chosen two representatives from each group - from the Vth generation materials Single Bond Adper and Prime&Bond NT and from the VIth generation materials Prompt-L Pop Adper and Xeno III. The materials of the Vth generation were combined with advised etching gels and by all adhesives the directions for use were strictly followed. Adhesive systems were combined with material Spectrum TPH. Each adhesive system was tested on 10 samples of intact third molars. The results showed extensive variability among reliability single adhesives without dependence to generations, that means self-etch or conventional total-etch. While measuring microleakage according to ISO/TS 11405:2003 (E) was the most reliable Prime&Bond NT, with score 12, than Xeno III with score 26. Between reliability of Single Bond Adper (score 37) and Prompt L-Pop Adper (score 38) there was no significant difference. The results demonstrated no significant difference between single generations of adhesive systems and proved that the quality of each product is the most important, whether it belongs to self-etch or conventional total-etch generations
