I’m a dental hygiene student and I have my competency test on debridement this week.. I was told my client has “slightly tenacious” calculus and I’m pretty confident that I will do well. I just find that it is hard for me to scale subgingivally in deeper pockets in the interproximal areas. I’ve tried using more lateral pressure, correct adaptation and a power assisted fulcrum but it’s still tough. The competency test does not allow us to use the ultrasonic so it has to be done with hand instruments .. any tips ? 🙁
