English Abstract

Aims: The aim of this study is to evaluate the effect of a prepared coating material (monopoly) on the microleakage at the interface of two temporary soft denture lining materials (Tru-soft and Bony plus) with the acrylic resin denture base.

Methods: Sixty specimens for microleakage were prepared, each lining material had thirty.

The specimen was in a disc shape 30mm diameter and 4mm thickness (2mm for acrylic resin denture base part and 2mm for soft lining material part).

Tru-soft and Bony plus lining materials were bonded to three groups of denture base surface treatments (untreated, sandblasted and monomer treated denture base).

A prepared coating material (monopoly) was applied at the junction of the denture base with the soft lining material, the specimens were placed in 2℅ methylene blue dye for two immersion periods (one week and one month) and the microleakage degree was measured by a microscope.

Results: Results of each lining material were analyzed separately and showed that for the two lining materials, there was a significant difference (p < 0.001) between coated and uncoated groups in all denture base surface treatments and in the two periods of immersion.

Conclusions: The coating material was effective in decreasing microleakage between the soft lining materials and the denture base when compared with the uncoated groups of the temporary denture lining materials
