Effect of Antibiotic Prophylaxis on Early Loss of Implants Installed by Unexperienced Operators.

Routine use of antibiotics for dental implant installation is widely applied in dental practice to prevent postoperative infection and implant loss. However, the effectiveness and necessity of such protocols have not been consensual in the literature. This study aimed to evaluate the effect of antibiotic prophylaxis on survival of dental implants placed in clinically healthy patients by unexperienced operators.

Photodynamic therapy associated with full-mouth ultrasonic debridement in the treatment of severe chronic periodontitis: a randomized-controlled clinical trial.

Achieving primary closure and enhancing aesthetics with periodontal microsurgery.

The continuous search for improved surgical procedures to address gingival deformities is a consequence of an increasing demand for aesthetics in the periodontal clinical practice. Innovative techniques have been reported to help clinicians achieve predictability in root coverage. Significant progress can be attributed to the inclusion of the operative microscope in periodontal therapy, particularly in regards to obtaining primary closure.

The effect of one session of supragingival plaque control on clinical and biochemical parameters of chronic periodontitis.

Supragingival plaque control is a requisite for the success of any periodontal procedure. However, little is know about the effect of this procedure alone on periodontitis. The aim of this study was to determine the effect of supragingival plaque control on clinical and biochemical parameters of chronic periodontitis.
