A prophylaxis angle, or prophy angle, is the instrument utilized to polish teeth during a dental cleaning. This handpiece attachment connects to a slow-speed rotary dental handpiece and holds a disposable polishing cup or brush. It allows dental professionals to efficiently and effectively remove plaque and extrinsic stains from the tooth surfaces. The angle design aids in reaching all areas of the oral cavity. An orthodontist, while primarily focused on aligning teeth and jaws, may use this tool during certain procedures or to maintain optimal oral hygiene throughout treatment.
The use of a prophylaxis angle plays a crucial role in maintaining dental health. Polishing the teeth removes superficial stains and smooths the enamel, making it more difficult for plaque to adhere. This process helps prevent gingivitis, periodontitis, and dental caries. Historically, tooth polishing was performed with a variety of abrasive pastes and techniques, but the introduction of the prophy angle significantly improved the efficiency and precision of the procedure. Its ergonomic design reduces operator fatigue and increases patient comfort.
