Actual (reported)Ultrasonic scalers have been shown effective in removing subgingival calculus. However, it may cause alteration to the tooth surface as well as discomfort to patients. Advances in scaler tip designs may reduce these effects. Limited studies have investigated the influence of scaler tip designs on tooth surface and patients' comfort. This study aimed to evaluate the influence of scaler tip designs on patients' pain perception.

Actual (reported)Pain perception
Pain perception was assessed using the Visual Analogue Scale (VAS), which consists of a line numbered from 0 to 10. Scale '0' indicates no pain, whereas scale '10' indicates the worst possible pain. Participants were asked to score any number between these two ends that described the pain they experienced during treatment
