Scaling patients teeth is not just scraping calculus off, it is way more than that ! Hygienists go through a rigorous training to learn to not only successfully remove calculus but also to examine surrounding tissues for inflammation and educate patients how to take care of the tissues as post care, prevent future incidences and taking care of their overall health. Please by giving assistants the power to remove “just sub gingival” calculus will put patients’ health in jeopardy, since they lack the in depth knowledge of oral anatomy, pharmacological studies and medical disorders that might also need addressing when performing scaling. So no to assistants performing scaling!
