Treatment of Advanced Periodontitis Using an Oscillating Chitosan Device Versus Regular Curettes Alone

Treatment of Localized Advanced Periodontitis Using an Oscillating Chitosan Device Versus Regular Curettes Alone - a Randomized Parallel Arm Clinical Trial

40 patients diagnosed with localised periodontitis will be included at each center, 20 patients will be treated with the control treatment, 20 patients will be treated by test treatment.

2.3 This will be a prospective multicentre parallel arm randomized clinical trial of 6 months' duration. Clinical parameters of periodontal disease will be recorded at baseline and at 6 months. Radiographs will be taken at baseline and at 6 months.Treatment will be performed at baseline and thereafter every three months.

2.5 Study setting Patient screening, inclusions and all clinical examinations will be performed by a board-certified specialist in periodontology at the test centres. Treatment will be performed by a registered separate therapist, either dentist or dental hygienist.

2.7 Treatment allocation Patients will be allocated to one of the following treatments: control (curettes+ ultrasound scaler (USS) supra and subgingivally), test (curettes + USS supra and chitosan brush in oscillating handpiece subgingivally) by computer-generated block randomization to ensure equal sample sizes.
