Summary
Palaseal denture glaze initially reduced plaque but failed long-term. Cracks in the glaze after three months led to increased bacterial colonization on dentures.
Area of Science:
- Biomaterials Science
- Dental Materials
- Microbiology
Background:
- Denture plaque accumulation is a significant clinical concern.
- Effective denture surface treatments are needed to reduce microbial adhesion.
Purpose of the Study:
- To evaluate the in vivo efficacy of Palaseal denture glazing material.
- To assess its impact on plaque colonization on denture fitting surfaces.
Main Methods:
- Ten subjects received temporary partial removable dentures with Palaseal applied to one half of the fitting surface.
- Denture fragments were collected at one and three months post-insertion.
- Scanning electron microscopy was used to analyze plaque colonization.
Main Results:
- At one month, plaque film was thinner on the Palaseal-glazed surfaces compared to non-glazed surfaces.
- At three months, glaze cracking occurred, leading to dense bacterial plaque accumulation on both glazed and non-glazed areas.
- The glaze facilitated plaque removal when intact but created microretentive areas upon cracking.
Conclusions:
- Palaseal denture glazing does not prevent bacterial colonization long-term.
- Initial plaque reduction is observed, but glaze integrity is crucial for sustained efficacy.
- Denture surface glazing can potentially increase plaque accumulation if the glaze layer degrades.
