Summary
Adults wearing removable dental prostheses have poor cleanliness, with an average of 37.06% plaque coverage. Standardized methods for assessing prosthesis plaque are lacking, hindering research and clinical application.
Area of Science:
- Dental prosthetics
- Oral hygiene
- Public health
Background:
- Removable dental prostheses are common among adults.
- Assessing plaque coverage on these prostheses is crucial for oral health.
- Current methods for plaque assessment lack standardization.
Purpose of the Study:
- To evaluate methods for assessing plaque area on removable dental prostheses.
- To conduct a meta-analysis on the cleanliness status of prostheses in adult patients.
- To quantify prosthesis cleanliness using computerized planimetric assessments.
Main Methods:
- Systematic review and meta-analysis registered with PROSPERO.
- Literature search across multiple databases (PubMed, MEDLINE, Embase, Cochrane, Scopus).
- Meta-analysis of 12 studies using computerized planimetric assessments for plaque quantification.
Main Results:
- A pooled plaque coverage area of 37.06% was estimated using computerized planimetric assessments.
- Considerable heterogeneity was observed in the meta-analysis.
- Subgroup analysis using Adobe Photoshop significantly reduced heterogeneity (I²=0%).
Conclusions:
- Adult patients exhibit poor cleanliness of their removable dental prostheses.
- A significant lack of standardized plaque quantification methods exists for research and clinical use.
- Most studies currently rely on less objective visual indices for plaque assessment.
