Rationale of mechanical plaque control.
Patients who have received extensive periodontal treatment also demonstrate a high susceptibility to periodontal disease. Maintenance of periodontal health following therapy includes a lifelong supportive care consisting of daily removal of the microbial plaque by the patient, supplemented by professional care in an individually designed programme. Mechanical supragingival plaque control by self care is of utmost importance. The goal is to create a positive attitude by information and motivation to give the patient knowledge and confidence. The patient should be advised to use appropriate aids and technique. A soft brush, an interspace brush, interdental tooth brushes or tooth picks are recommended in periodontal patients. Professional tooth cleaning involves removal of supragingival plaque from all tooth surfaces using mechanically driven instruments and fluoride prophy paste and, when indicated, removal of calculus and subgingival plaque. Disclosing solution is used to visualize the plaque to the patient and to the clinician in order to reinforce instruction in oral hygiene. Oral hygiene measures alone seem to have limited effect on subgingival microflora in cases of severe disease. In shallow and moderately deep pockets a good plaque control can change the subgingival flora towards a more "healthy" composition. Subgingival plaque removal is performed with hand- and/or ultrasonic instruments. Cracks within the cementum, grooves, fissures, resorption lacunae, furcations may create difficulties in cleaning the root surface. Ultrasonic instrumentation has a beneficial effect in creating a smooth surface without extensive removal of cementum. Besides, the cavitational activity contributes to plaque removal which makes the instrument further suitable during maintenance therapy. The result of the debridement is assessed on the healing response in the tissues. The frequency of maintenance visits must be given on an individual basis according to the needs of every special patient. The visit includes plaque evaluation (disclosion), oral hygiene instruction, probing depth measurements, registration of bleeding on probing, scaling (plaque removal) if indicated, tooth polishing, fluoride application and radiographs if indicated. The goal is to identify and treat signs of recurrence of periodontal disease in order to prevent further loss of attachment.
