    Recently, oscillating brushes, equipped with air scalers, have been introduced, and are widely accepted as alternatives to rotating instruments for Professional Mechanical Tooth Cleaning (PMTC). In terms of the intraoral condition, composite resins are commonly used to restore teeth with caries and/or wedge-shape defects around the cervical region. There is a possibility that this type of brush has an adverse effect on the surface of fillings such as resin composites. The purpose of this study was to investigate the influence of using an oscillating brush equipped with an air scaler for PMTC on the surface roughness (Ra) of two different types of resin composites. The surface textures of the resin composites after PMTC were observed by scanning electron microscopy. The results of this study showed that the type of the resin composite and the method of PMTC were factors significantly influencing the surface roughness of the resin composites. Use of rotary instruments and ultrasonic scalers for PMTC significantly increased the Ra value. There was no significant influence of the use of an oscillating brush equipped with an air scaler for brushing. This study suggests that the use of an oscillating brush equipped with an air scaler was not associated with any adverse effect on the surface texture of the resin composites examined, and that this type of brush can be used safely in clinical situations.

    A questionnaire survey regarding dental implant therapy was conducted of approximately 900 trustees and specialists of the Japanese Society of Periodontology between July and September 2010. Among the 283 (31%) valid responses, 82% had experience with dental implant therapy and 78% had undertaken dental implant therapy for patients with periodontal disease. Furthermore, 65% of the respondents had performed bone augmentation and additional treatments to the surrounding mucosa at the time of implant surgery. Post-surgical implant maintenance had been undertaken by nearly all respondents, however, 73% had experienced implant failures or complications, regardless of whether they practiced at other clinics or at their own clinic. The present findings revealed that trustees and medical specialists of the Japanese Society of Periodontology who responded to the present survey conduct basic periodontal treatment and dental implant therapy for patients with a history of periodontal disease. However, it was also clarified that the therapy was sometimes undertaken without an effort made to eliminate risk factors such as smoking.
