Conscientious self-application of oral hygiene procedures by the patient is related to the need to obtain and to keep plaque-free teeth. This need is aroused by pleasant aspects. One appointment is reserved to demonstrated proper plaque control techniques. Instruction on the correct brushing method is explained with the aid of demonstration models and afterwards in the mouth with the use of a hand mirror. It is necessary to confirm the effectiveness of the instructed method in plaque removal with each patient. We describe a modified BASS toothbrushing technique. Patients without periodontitis, for example in case of chronic gingivitis, are instructed for flossing. Patients with periodontitis receive instruction for use of interdental cleaning (floss and/or interproximal brushes). Patient motivation is repeated during treatment period, control routine visit and maintenance phase. At each visit, technique efficiency is controlled visually or by bleeding test and plaque control is corrected.
