Effect of denture surface glazing on denture plaque formation

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.

Evaluation of surface physical properties of acrylic resins for provisional prosthesis

“…Furthermore, to improve surface quality, Mantikos et al 25 propose the application of a layer of glaze, claiming that in provisional restorations, this procedure is indicated to reduce bacterial attachment. However, Sesma et al 26 demonstrated that glaze applied on definitive surfaces did not prevent bacterial attachment, although it aided its removal.…”

Efficacy of denture cleaners on the surface roughness and <i>Candida albicans</i> adherence of sealant agent coupled denture base materials

“…Palaseal surface sealant agent selected for this study is a light-cured sealer that adhere to all denture materials and has high resistance to solvents 23) . Sesma et al 24) reported that sealant agent coupling (Palaseal) may improve the physical properties of dentures with smoother surface, decrease plaque adhesion and bacterial colonization, which results in good oral hygiene. Consistent with this results, no significant difference was found between the initial surface roughness values (R a0) of all tested denture base materials in present study, which had been coated with Palaseal sealant agent before.…”

“…Sesma ve ark. 19 cila materyallerinin protez yüzeyindeki plak formasyonuna etkinliğini değerlendirdikleri in vivo çalıĢmalarında, Palaseal uygulanan protezlerin taramalı elektron mikroskop görüntüle-rinin, Palaseal uygulanmayanlara göre daha düzgün olduğunu bildirmiĢlerdir. Hareketli protezlerin hastaya teslimi sırasında veya sonrasında yapılan aĢındırmalara bağlı olarak açığa çıkan pürüzlü yüzeylerin düzenlenmesi amacıyla da cila pastaları veya silikon cila kitleri kullanılmak-tadır.…”
