Design of studies to evaluate plaque control agents.

Area of Science:

• Periodontology
• Microbiology

Background:

• Dental plaque is a primary etiological factor in periodontal diseases.
• Understanding plaque's role is essential for effective disease management.

Purpose of the Study:

• To review the significance of dental plaque in periodontal disease development.
• To survey existing indices for quantifying plaque in clinical research.
• To examine recent studies on agents that inhibit plaque formation.

Main Methods:

• Literature review of periodontal disease etiology.
• Survey of plaque indices used in clinical trials.
• Analysis of published research on plaque-inhibiting agents.

Main Results:

• Plaque's central role in periodontal disease etiology is confirmed.
• Various plaque scoring indices exist, each with limitations.
• Clinical trial designs and population characteristics influence scoring.
• Recent studies show promise for novel plaque-inhibiting agents.

Conclusions:

• Plaque remains a key target for periodontal disease prevention and treatment.
• Standardization of plaque assessment in clinical trials is needed.
• Further research into effective plaque-inhibiting agents is warranted.
