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

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.

Treatment and study plan

Er: YAG Laser

Procedure

Scaling and root planing at baseline and surgery for remaining deep pockets after 6 months both using Er:YAG laser

Conventional treatment 1(ultrasonic and manual means)

Procedure

Scaling and root planing at baseline and surgery for remaining deep pockets after 6 months both using conventional methods : ultrasonic and manual means

Conventional treatment 2 (ultrasonic and manual means)

Procedure

Surgery at baseline for all deep pockets using conventional methods: ultrasonic and manual means

Primary outcomes

  1. Probing pocket depth, Clinical attachment level and microbiological analysis

    Time frame: At baseline, 3, 6, 12, 24, 36, 48 and 60 months

Secondary outcomes

  1. Gingivitis index, plaque index, bleeding on probing at the same time intervals + the number of interventions

    Time frame: After 5 years

  2. 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

  3. 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
