Summary
Periodontal indices like plaque and bleeding scores fluctuate significantly within a single day, especially in severe cases. Accurate periodontal assessment requires multiple daily measurements, not just one.
Area of Science:
- Periodontology
- Dental Diagnostics
Background:
- Periodontal indices are traditionally considered stable over 24 hours.
- Daily variations in these indices have significant clinical implications but are poorly understood.
Purpose of the Study:
- To investigate the diurnal variations of key periodontal indices.
- To determine if these changes correlate with baseline periodontal severity.
Main Methods:
- A preliminary study involving 56 patients receiving cause-related therapy.
- Measurement of Full-Mouth Plaque Score (FMPS), Full-Mouth Bleeding Score (FMBS), Periodontal Screening and Recording (PSR), and Periodontal Risk Assessment (PRA) thrice daily (08:30, 11:30, 14:30) over 24 hours.
- Statistical analysis using Stata to correlate index changes with baseline severity.
Main Results:
- All measured periodontal indices showed improvement post-therapy.
- Significant diurnal variations were observed in FMPS, FMBS, and PRA.
- Patients with more severe baseline periodontal conditions exhibited greater daily fluctuations in indices.
- PSR scores did not show significant daily changes.
Conclusions:
- Periodontal indices demonstrate significant daily variation, challenging the assumption of 24-hour stability.
- The magnitude of daily index fluctuation is linked to the baseline severity of periodontal disease.
- Accurate periodontal assessment, particularly for severe cases, necessitates multiple daily measurements at standardized times to account for diurnal variations.
