Abstract

The bond strengths of dentinal bonding systems to dentin and the microleakage at the dentinal bonding system to dentin interface are often determined in laboratory studies prior to the clinical evaluation of these systems. The shear bond strengths of some of the third generation dentinal bonding systems to dentin and the microleakage at the dentinal bonding system to dentin interface are discussed. In addition, the shear bond strengths of fluoride-containing liners/bases and the fluoride release from these systems are evaluated.

Shear bond strengths of orthodontic plastic brackets.

The purpose of the present study was to evaluate the shear bond strengths of plastic brackets and the influences of the bracket filler contents on the bonding. The shear bond strengths of 4 plastic brackets (Spirit; Spirit MB; Clear Bracket; Aesthetic-Line) bonded to enamel with 4 orthodontic adhesives (Orthomite Superbond; System 1+; Transbond XT; and Kurasper-F) were compared with the strength of a conventional metal bracket. The findings of this study indicated the following: (1) shear bond strength of the 4 plastic brackets was significantly lower than that of the conventional metal brackets (P <.05), with most of the values ranging from 3 MPa to 6 MPa; (2) when comparing the bond strengths of plastic brackets, Aesthetic-Line had the largest value followed by Spirit MB, Spirit, and Clear Bracket, and when the plastic brackets were bonded with Orthomite Superbond, they showed relatively stronger bond strengths than when bonded with the other adhesives. Clear Bracket showed relatively lower values especially when bonded with System 1+; (3) the application of primer did not increase the durability of the bond strengths when bonding Spirit and Clear brackets; and (4) fillers contained in each plastic bracket ranging from 9.18% to 19. 52% were fairly well distributed and showed the same morphology of a fiber type 10 microm in diameter with different lengths. The filler concentration tended to correlate with the bond strength. The exposed fillers on the bracket base surface may play a more important role in plastic bracket adhesion than the macro-morphology of the base surface.

[Examination of silane ceramic systems by differential thermoanalysis].

In the present study two silane adhesive agents (Silicoup, Heraeus/Kulzer, and Monobond-S, Vivadent) and one type ceramic (VITA VKM 68) and their interface reactions were tested by thermo-analysis. The ceramic powder is thermally inactive. Using the two different silane solutions with the same ceramic type different thermical characteristics were found despite the same base material (gamma-methacryloxi-propyl-trimethoxi-silane). This can probably be attributed to the different configurations of the polycondensates.
