Treatment of Periodontitis Using Er:YAG Laser vs. Conventional Treatment Modalities

Not Applicable

Completed

• Conditions: Chronic Periodontitis
• Interventions: Procedure: Conventional treatment 2 (ultrasonic and manual means); Procedure: Conventional treatment 1(ultrasonic and manual means)

• Registration Number: NCT00669253
• Lead Sponsor: University Hospital, Ghent

Brief Summary

Conventional non-surgical periodontal treatment, that is, root debridement using manual and ultrasonic means at baseline and surgery using the same means after 6 months in case of persistent deep pockets (Group 1)/ Er:YAG laser used in a non-surgical approach at baseline and surgery using the same laser after 6 months in case of persistent deep pockets (Group 2)/ Surgery at baseline using manual and ultrasonic means (Group 3). All patients will undergo supragingival maintenance on a yearly basis.

Arm && Interventions

Group	Intervention	Description
3	Conventional treatment 2 (ultrasonic and manual means)	Surgery at baseline for all deep pockets using conventional methods (ultrasonic and manual means)
2	Conventional treatment 1(ultrasonic and manual means)	Scaling and root planing at baseline and surgery for remaining deep pockets after 6 months both using conventional methods (ultrasonic and manual means)

Primary Outcome Measures

Name	Time	Method
