The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
University Hospital, Ghent
  Purpose
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.

Condition Intervention
Chronic Periodontitis Procedure: Er: YAG Laser Procedure: Conventional treatment 1(ultrasonic and manual means) Procedure: Conventional treatment 2 (ultrasonic and manual means)

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
Official Title: Randomized Controlled Trial to Evaluate the Efficacy of Er:YAG Laser and Surgical Therapy in Treatment of Chronic Periodontitis

Further study details as provided by University Hospital, Ghent:

Primary Outcome Measures:
  • Probing pocket depth, Clinical attachment level and microbiological analysis [ Time Frame: At baseline, 3, 6, 12, 24, 36, 48 and 60 months ]

Secondary Outcome Measures:
  • Gingivitis index, plaque index, bleeding on probing at the same time intervals + the number of interventions [ Time Frame: After 5 years ]
  • Consumed time per treatment/ Patient satisfaction/comfort ( Oral Health impact Profile : OHIP )/ The estimated financial costs based on average data delivered for instance by the Belgian Society of Periodontology [ Time Frame: After 5 years ]
  • Adverse effects described by the patient (number of painkillers taken, visual analogue scale to monitor post-operative pain, tooth sensitivity) [ Time Frame: After 5 years ]

Enrollment: 60
Study Start Date: June 2008
Study Completion Date: December 2012
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
