Clinical Trial Summary

Erythritol is a natural sugar alcohol (a four-carbon polyol) produced by the reduction of erythrose. It is considered safe as food additive and has many of the functional properties that are important for subgingival debridement. Current evidence includes no prospective studies comparing the outcomes of a low abrasive erythritol air-polishing as an adjunctive therapy to conventional titanium and ultrasonic debridement of patients in a maintenance program with peri-implantitis. Thus, the main purpose of this randomized, single-masked controlled trial (RCT) is to assess whether low abrasive erythritol air-polishing has an adjunct effect to conventional non-surgical treatment of peri-implantitis.

Description:

This RCT will enroll subjects among patients in need for non-surgical treatment of peri-implantitis at a private dental clinic in Stavanger, Norway. Forty patients diagnosed with peri-implantitis on at least one implant will be randomly allocated by tossing a coin into test or control group. Patients with cement-retained and screw-retained supraconstructions will be included. Treatment of peri-implantitis will be performed by one operator (AS) at baseline, 3-, 6-, 9- and 12-month follow-up visits. Local anesthesia will be used when needed. In the test group, implants will be treated with titanium curette, ultrasonic device and a specially designed nozzle mounted on a hand piece (Perio-Flow) connected to an airflow unit. In the control group, implant with peri-implantitis will be debrided with titanium curette and ultrasonic device only. Test and control debridement will be performed without time limit. The treatment will continue until the operator is judging the implant surface to be free for supra- and subgingival deposits.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Changes in probing depth (PD)	PD as the distance in mm from the implant mucosal margin to the probable base of the pocket at six sites;	12 moths
Primary	Crestal bone level (CBL)	Intraoral digitalized radiographs will be taken with customized Eggen-holder and long cone, parallel technique to assess CBL. The distance from implant platform to the mesial and distal bone levels will be measured by using the software program DIGORA (Soredex, Helsinki).	12 months
Secondary	Bleeding on probing (BoP)	BoP as the presence of bleeding after gentle probing (Renvert et al. 2017).	12 months
Secondary	Gingival crevicular fluid (GCF)	Sample sites will be isolated with cottons rolls, carefully cleaned for supragingival plaque and air-dried. A perio paper strip will then be gently placed one to two mm into the entrance of the pocket and left in place for 30 seconds.	12 months
Secondary	Visual analogue scale (VAS)	The scorings will be performed following completion of the debridement at baseline and at 6 and 12 months with 0 = "no pain" and 100 = "worst pain I can imagine".	12 months
