Timing of Re-evaluation After Steps I-II of Periodontal Therapy

Timing of Re-evaluation After Steps I-II of Periodontal Therapy: a Randomized Clinical Trial

Literature on non surgical periodontal therapy (NSPT) shows lack of clarity in reporting information on re-evaluation timing and clinical response. If the re-evaluation was done shortly after NSPT, this is also likely to have an influence on the surgical treatment plan. The aim of this randomized clinical trial is to investigate the effect of re-evaluation timing at 1-3-6 months after NSPT in terms of pocket closure, probing pocket depth reduction, comprehensive treatment plan, and costs for the patient.

Inclusion Criteria:

• Periodontitis stage III-IV
• Full-mouth plaque score (FMPS) < 25% at the 1-month re-evaluation
• Full-mouth bleeding score (FMBS) < 25% at the 1-month re-evaluation
• Signed informed consent

Exclusion criteria:

• Age < 18 yo
• Pregnancy or lactation
• Heavy smokers (>10 die)
• Conditions or diseases influencing periodontal healing
• Patients that cannot complete the 6 months follow-up
