Clinical Efficacy of Full-Mouth Ultrasonic Debridement against Partial-Mouth Ultrasonic Debridement in the Treatment of Chronic Periodontitis: Full-Vs Partial-Mouth Debridement

Aim: To compare the clinical benefit of full-mouth ultrasonic debridement against partial-mouth ultrasonic debridement in patients with chronic periodontitis up to 3 months after therapy. Materials & Methods: Sixty patients with probing pocket depth ≥ 5 mm were randomly assigned to evaluate the clinical efficacy of full-mouth ultrasonic debridement against partial-mouth ultrasonic debridement in the treatment of advanced chronic periodontitis. Results: There was a reduction in the levels of probing pocket depth and relative attachment level but no statistically significant difference between treatment groups in intervals of 30, 60 and 90 days. For bleeding following pocket probing, was found statistical difference for 30 and 60 days, where the groups of full-mouth showed more reduction than conventional therapy. But in 90 days, there was no significant difference between groups. Conclusion: At the evaluation 90 days after treatment, no statistical difference was found be- tween the two periodontal therapies. Clinical relevance: This study tried to verify if full-mouth ultrasonic debridement provides clinically relevant improvements in the periodontal treatment.
