Abstract
This study evaluated, in vivo, the efficacy of a denture glazing material (Palaseal) in modifying plaque colonization of dentures. Ten subjects were selected and received maxillary temporary partial removable dentures, with complete acrylic palatal coverage. The right half of the fitting surface of the denture bases were glazed with Palaseal, whereas the other half was not glazed. One month after insertion, two fragments of the resin base of all dentures were removed (one from the glazed side and another from the non-glazed side). These samples were prepared and examined by scanning electron microscopy. Three months after insertion, other fragments were obtained and analyzed. Microscopic observation at 1 month revealed that, for all patients, the plaque film was thinner on the treated side in comparison to the non-treated side. However, at the 3-month evaluation, some areas of the glaze showed cracking, and both glazed and non-glazed sides were covered by a dense bacterial plaque film. In conclusion, the findings of this clinical experiment showed that glazing denture's fitting surface did not prevent bacterial colonization, but favored plaque removal while the glaze layer remained intact. After three months, glaze cracks created microretentive areas that increased plaque accumulation.
Highlights
The correlation between dental plaque and gingival problems has been well established since the 1960s, thereafter professionals became aware of the importance of plaque control and patients started to get involved in personal daily oral hygiene
The glazed resin surface appeared covered by a thin layer of bacterial plaque, with small number of microorganisms (Fig. 2), while the non-glazed surfaces showed dense plaque formation, rich in microorganisms (Fig. 3)
The aim of this study was to evaluate the real effect of denture surface glazing on bacterial plaque formation
Summary
The correlation between dental plaque and gingival problems has been well established since the 1960s, thereafter professionals became aware of the importance of plaque control and patients started to get involved in personal daily oral hygiene. Denture stomatitis is one of the oral infections associated to the use of dentures It is a chronic disease characterized by either localized/generalized inflammation or inflammatory papillary hyperplasia that may affect patients wearing complete or partial removable prostheses in one or both dental arches. It may be highly prevalent and hard to treat due to its multifactorial etiology [2,3]. The combination of systemic factors, such as nutritional deficiency, diabetes, physical debilitation, immune suppression, and local factors, such as trauma caused by the prosthesis, fungal and bacterial infections and lack of hygiene, can make patients more susceptible to denture stomatitis [4]
