microleakage evaluation in regard to cavo-surface designs & treatments

Resin composite repair: Quantitative microleakage evaluation of resin-resin and resin-tooth interfaces with different surface treatments

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...

The effect of different surface treatments of demineralised enamel on microleakage under metal orthodontic brackets

BACKGROUND The aim of this investigation was to assess the effects of different treatments of demineralised enamel on microleakage under orthodontic brackets. METHODS Seventy-five intact premolars were randomly assigned to five groups. The teeth in groups 2 through 5 were immersed in a demineralising solution for 16 weeks. In groups 1 (control) and 2 (demineralised/control), conventional acid...

Nanoionomer: evaluation of microleakage.

BACKGROUND Glass ionomer cements are widely used in pediatric practice due to their advantage of fluoride release and chemical bond to tooth structure. Adherence of the restorative material to the cavity walls is one of the most important characteristic for it to be proven as an ideal material as it prevents microleakage. AIMS AND OBJECTIVES This study was aimed at evaluating the microleakage...

Randomization tests for restricted alternating treatments designs.

Alternating Treatments Designs (ATD) with random assignment of the treatments to the measurement times provide very powerful single-case experiments. However, complete randomization might cause too many consecutive administrations of the same treatment to occur in the design. In order to exclude these possibilities, an ATD with restricted randomization can be used. In this article we provide a ...
