Clinical Trial Data on Denture Cleaning Methods and Biofilm Outcomes

Two clinical studies from the University of Hong Kong Faculty of Dentistry provide quantitative data on denture hygiene in older adults. A cross-sectional study of 97 denture wearers and a crossover randomized controlled trial of 56 participants compare ultrasonic cleaning with manual brushing. Outcome measures include percentage plaque area coverage, denture cleanliness index, microbial index, denture stomatitis, and patient-reported outcomes.

Use Cases

• Comparing the efficacy of ultrasonic versus manual brushing denture cleaning methods based on plaque area coverage and microbial index.
• Analyzing sociodemographic and clinical factors associated with denture biofilm levels in a cross-sectional cohort.
• Evaluating patient-reported outcome measures (PROMs) related to different denture cleaning interventions.
• Investigating the relationship between denture cleanliness and clinical conditions like denture stomatitis.

Strengths

• Includes data from a randomized controlled trial (RCT) with a crossover design, a robust method for comparing interventions.
• Combines objective clinical measures (plaque coverage, microbial index) with subjective patient-reported outcomes.
• Contains data from two distinct study designs: a cross-sectional study (n=97) and a prospective RCT (n=56).

Limitations

• Column names and a precise row count are not provided, limiting understanding of the data structure.
• The dataset size is given as 118090 bytes, which suggests a relatively small dataset.
• The future 'last updated' date (2026-03-18) is inconsistent and should be verified.
