Conditions

Chronic Periodontitis

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.

Interventions

PROCEDUREEr: YAG Laser

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

PROCEDUREConventional 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

PROCEDUREConventional treatment 2 (ultrasonic and manual means)

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

Design outcomes

Primary

Measure	Time frame
Probing pocket depth, Clinical attachment level and microbiological analysis	At baseline, 3, 6, 12, 24, 36, 48 and 60 months

Secondary

Measure	Time frame
Gingivitis index, plaque index, bleeding on probing at the same time intervals + the number of interventions	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	After 5 years
Adverse effects described by the patient (number of painkillers taken, visual analogue scale to monitor post-operative pain, tooth sensitivity)	After 5 years
