Clinical outcomes of performance of dental students using erythritol powder by means of air polishing with ultrasonic debridement with students' assessment: Part II.

Objective: Assessment of a dental student's clinical performance is essential for providing feedback for improving education. This study evaluated the ability of undergraduate dental students to treat periodontal patients with two techniques, ultrasonic debridement with polishing (UD+P) and the erythritol powder air polishing with ultrasonic instrumentation (EPAP+UD) in a split-mouth design.

Methods: The study was conducted on undergraduate students with patients suffering from gingivitis and stage I periodontitis with grade A.

Clinical outcomes of using erythritol powder by means of air polishing with ultrasonic debridement in the treatment of initial periodontal pockets in hand of dental students: A split-mouth, randomized, comparative, controlled study. Part I.

Objective: The purpose of this trial was to evaluate the clinical efficacy and patient acceptance of using the erythritol powder air polishing with mechanical debridement in non-surgical periodontal therapy.

Methods: The trial was conducted as a split-mouth design study of 6 weeks' duration including 13 patients with gingivitis and stage I periodontitis with grade A. Each patient received ultrasonic debridement and polishing (UD+P) on one side, whereas the contralateral side was treated by erythritol powder air polishing and ultrasonic instrumentation (EPAP+UI) when required.
