Summary
Denture plaque assessment methods were reviewed, finding indices simpler but computerized planimetry more accurate for evaluating denture hygiene and preventing disease.
Area of Science:
- Oral Health and Microbiology
- Biomaterials and Dental Prosthetics
Background:
- Denture plaque, a biofilm on dentures, is linked to oral and systemic diseases.
- Quantitative assessment of denture plaque is crucial for evaluating denture hygiene and disease prevention.
Approach:
- Systematic review of visual denture hygiene assessment methods (plaque indices and planimetries).
- Searched PubMed, Medline, Embase, Cochrane Library, and Google Scholar up to March 2022.
- Included 74 studies, analyzing assessment details like disclosing agent use and surface grading.
Key Points:
- 60 studies used denture plaque indices; 18 used planimetries.
- Most studies (43/60 indices, 17/18 planimetries) employed disclosing agents.
- 21 indices were identified, grading either divided or entire denture surfaces.
- Planimetric methods included image analysis and computer-aided pixel quantification.
Conclusions:
- Denture plaque indices are popular due to simplicity in plaque assessment.
- Computerized planimetric assessment offers higher accuracy, reducing subjectivity and assessor error.
- Accurate plaque load assessment is vital for managing denture biofilm-associated diseases.
