Resumen breve

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.

Descripción detallada

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.

Etiqueta: Oscillating Chitosan Device

Tipo: Experimental

Descripción: The brush bristles of the test device (Labrida BioClean®, LABRIDA AS, Oslo, Norway) are made of the biopolymer chitosan. Any debris left from the chitosan bristles is completely biocompatible and will dissolve or be resorbed, thus not causing harm to the tissues.surrounding the tooth. Chitosan is made from chitin derived from shell of marine crustaceans such as shrimp and crab, however chemically modified and thus not even considered to be animally derived. Chitosan has been approved for use in e.g., surgical bandages, as a haemostatic agent and as dietary supplement used in a wide range of nutritional and health products. Chitosan has also been documented to be non-allergenic and it has been suggested that chitosan has anti-inflammatory properties.
