Abstract

Background: Tissue conditioners are required to function over relatively long time to treat inflamed, irritated, or distorted tissues. Most currently available materials have a short life span (three to four days).  Objectives: This in vivo study was designed to evaluate and compare the effect two different surface coatings on surface integrity and softness of tissue conditioner over a period of time.  Materials & Methods: In this in vivo study ten completely edentulous subjects with moderate ridges were selected. Maxillary and mandibular complete dentures were fabricated. Six troughs (3×5×2 mm) were prepared in maxillary denture. They were filled with chemically cured tissue conditioner and covered with different surface coatings. Dentures were inserted in the patient’s mouth with proper instructions. The patients were recalled after one week and four weeks. The specimens were tested with Scanning Electron Microscope for surface integrity and with Shore A Durometer for softness. Statistical differences were determined with analysis of variance (p<0.05).  Results: Statistically significant difference was noted between control, Monopoly and Permaseal coated tissue conditioner. Scanning Electron Microscope analysis indicated that the control group deteriorated by the end of the first week, whereas both Monopoly and Permaseal remained intact for up to one week. All groups showed some amount of deterioration by the end of four weeks.
