Decision making in periodontal therapy. The re-evaluation.

Area of Science:

• Periodontology
• Dental Implantology

Background:

• Assessing periodontal attachment levels is crucial for treatment evaluation.
• Understanding factors contributing to probing attachment loss post-therapy is essential.

Purpose of the Study:

• To evaluate probing attachment changes after periodontal therapy.
• To determine the predictability of clinical signs for long-term probing attachment loss.

Main Methods:

• Monitoring 7 patients over 2 years and 17 patients over 3.5 years using triplicate probing measurements.
• Analyzing probing attachment changes at multiple time points relative to instrumentation.
• Using linear regression analysis to assess predictability of clinical signs for attachment loss.

Main Results:

• 24% of sites experienced probing attachment loss directly from instrumentation.
• 12% of sites lost attachment by 24 months, with a significant portion occurring during instrumentation.
• Persistent bleeding and increased probing depth showed the highest predictability for attachment loss over time.

Conclusions:

• Periodontal instrumentation can lead to direct probing attachment loss.
• Clinical signs like persistent bleeding and increased probing depth are valuable indicators for identifying sites at risk of future attachment loss.
• Considering therapy effects is vital when identifying sites with probing attachment loss.
