When in use, the terminal shank of the universal curette should be. Parallel to the axis of the tooth being debrided Parallel to the axis of the tooth being debrided At 90-degree angle to the axis of the tooth being debrided At 90-degree angle to the axis of the tooth being debrided Parallel to the surface of the tooth being debrided Parallel to the surface of the tooth being debrided At 70-degree angle to the axis of the tooth being debrided At 70-degree angle to the axis of the tooth being debrided None of the above None of the above #3. When in use, the face of the working end of the universal curette should be. Parallel to the axis of the tooth being debrided Parallel to the axis of the tooth being debrided At 90-degree angle to the axis of the tooth being debrided At 90-degree angle to the axis of the tooth being debrided Parallel to the surface of the tooth being debrided Parallel to the surface of the tooth being debrided At 70-degree angle to the axis of the tooth being debrided At 70-degree angle to the axis of the tooth being debrided None of the above None of the above #4. While sharpening the universal curette with the sharpening stone, the terminal shank should be facing towards. 11 o’clock 11 o’clock 12 o’clock 12 o’clock 1 o’clock 1 o’clock 2 o’clock 2 o’clock #5. While sharpening the universal curette with the sharpening stone the face of the working end should be. Parallel to the floor Parallel to the floor At 70-degrees to the floor At 70-degrees to the floor At 90-degrees to the floor At 90-degrees to the floor Parallel to the sharpening stone Parallel to the sharpening stone #6. Which of the following factors restricts the use of the ultrasonic scaler? Ceramic restoration Ceramic restoration Denuded root surface Denuded root surface Deep periodontal pocket Deep periodontal pocket Rheumatoid arthritis Rheumatoid arthritis #7. The ultrasonic tip should not be allowed to remain on the tooth surface for too long because it may: Stop the vibrations of the tip Stop the vibrations of the tip Burnish the calculus onto the tooth surface Burnish the calculus onto the tooth surface Damage the tooth/root surface Damage the tooth/root surface Damage the soft tissue surrounding the tooth/root Damage the soft tissue surrounding the tooth/root All above All above #8. What is the function of the water that circulates through the ultrasonic handpiece and exits as a spray? Acts as an anaesthetic agent and improves visibility Acts as an anaesthetic agent and improves visibility Serves as a cooling system for the ultrasonic tip and provides lavage Serves as a cooling system for the ultrasonic tip and provides lavage Increases efficacy of the vibrating tip and dissolves subgingival calculus Increases efficacy of the vibrating tip and dissolves subgingival calculus Removes biofim and discolorations from the pocket and reduces tooth sensitivity Removes biofim and discolorations from the pocket and reduces tooth sensitivity #9. While providing subgingival debridement with piezoelectric ultrasonic tip, what position of the tip will allow efficient calculus removal? Tip should be positioned like a curette with lateral surfaces against the root surface Tip should be positioned like a curette with lateral surfaces against the root surface Tip should be positioned like a probe with the back against the root surface Tip should be positioned like a probe with the back against the root surface Tip should be positioned like a curette with the face against root surface Tip should be positioned like a curette with the face against root surface Tip should be positioned like a probe with lateral surfaces against the root surface Tip should be positioned like a probe with lateral surfaces against the root surface #10. What is the main difference between scaling and root planning (SRP) and subgingival / root debridement. SRP refers to removal of subgingival biofilm, stains and necrotic root cementum while subgingival debridement refers to removal of subgingival calculus, preserving root cementum and underlying dentine SRP refers to removal of subgingival biofilm, stains and necrotic root cementum while subgingival debridement refers to removal of subgingival calculus, preserving root cementum and underlying dentine SRP refers to removal of subgingival biofilm, necrotic root cementum and dentine while subgingival debridement refers to removal of subgingival calculus, preserving root cementum and underlying dentine SRP refers to removal of subgingival biofilm, necrotic root cementum and dentine while subgingival debridement refers to removal of subgingival calculus, preserving root cementum and underlying dentine SRP refers to removal of subgingival biofilm, calculus and necrotic root cementum while subgingival debridement refers to removal of subgingival biofilm and calculus, preserving root cementum SRP refers to removal of subgingival biofilm, calculus and necrotic root cementum while subgingival debridement refers to removal of subgingival biofilm and calculus, preserving root cementum SRP refers to removal of subgingival biofilm and calculus, preserving root cementum while subgingival debridement refers to removal of subgingival biofilm and calculus and necrotic root cementum SRP refers to removal of subgingival biofilm and calculus, preserving root cementum while subgingival debridement refers to removal of subgingival biofilm and calculus and necrotic root cementum None of above None of above Finish
