Welcome! Through the years, dental hygienists only learned how to use conventional scaling techniques with a mirror in the non-dominant hand and a scaler in the dominant hand. Unfortunately, many musculoskeletal injuries have occurred as a result. My book on periodontal instrumentation and ergonomics demonstrates reinforced protective scaling strategies to help protect against injury. I am currently lecturing internationally and also facilitate hands-on dental hygiene workshops which help hygienists prevent injury and improve ergonomics while meeting current CE requirements.
