Coronoplasty in Periodontal therapy

 All the questions have been directly picked from Carranza 11th edition

 


1.      First step of Coronoplasty is

a.      Elimination of retrusive contact prematurities

b.      Elimination of working side contact prematurities

c.       elimination of balancing side interferences

d.      Elimination of excessive contact of anterior teeth



  Hint✅🔑 

Ans: A [Elimination of retrusive contact prematurities.]

 Steps of Coronoplasty

Step 1: Create positive patient acceptance

Step 2: Retrusive prematurities are eliminated

Step 3: Adjust Intercuspal position to achieve stable, simultaneous contacts

Step 4: Test for excessive contact on the incisor teeth (Fremitus)

Step 5: Remove posterior protrusive interferences and establish contacts bilaterally

Step6: Remove or lessen mediotrusive (balancing) interferences

Step 7: Reduce excessive cusp steepness on the laterotrusive (working) contacts.

Step 8: Eliminate gross occlusal disharmonies

Step 9: Recheck tooth contact relationships

Step 10: Polish all rough tooth surfaces

 

2.      The only clinical criteria used to test the efficacy of coronoplasty is

a.      reduction of pocket depth

b.      Reduction of gingival inflammation

c.       reduction of tooth mobility

d.      All of the above

Ans: c              Reduction of tooth mobility



3.      In bruxism patient, the muscle that exhibits overdevelopment is

a.      Lateral pterygoid                                                             

b.      Masseter

c.       Temporalis                                                                         

d.      Internal pterygoid

Ans: b Masseter

 


4.      Which of the following is not an indication of occlusal correction?

a.      Wear facets                                                                       

b.      Widening of periodontal ligament

c.       Pain during tooth contacts                                             

d.      TMJ symptoms



Ans: a              Wear facets

   Hint✅🔑 

Wear facets can be seen in normal teeth as well.

 

5.      Occlusal correction is done after periodontal therapy in which condition

a.      infrabony pockets                                                                        

b.      Suprabony pockets

c.       trauma from occlusion                                                                  

d.      Pseudopockets


   Hint✅🔑 

Ans: c Trauma from occlusion

 

 

6.      Occlusal guard/Maxillary splint is given in bruxism to

a.      Prevent bruxism

b.      Reduce pocket formation

c.       Reduce traumatic forces of tooth

d.      Prevent elongation of tooth


   Hint✅🔑 

Ans: c Reduce traumatic forces on tooth
