10 Questions
Match the following steps with the correct description in the step-back technique:
Insert files in a sequential order = Files are inserted into the root canal until the rubber stop contacts the occlusal reference point Work in a wet field = Irrigate often during the procedure Recapitulate often = Check the progress of the procedure frequently Start preparation 2-3 mm short of minor diameter = Modified Step-Back Technique is used
Match the following advantages with the correct description in the step-back technique:
Better tactile awareness = Keeps apical preparation small in its original position Ability to prepare proper apical stop = Gradual taper is achieved Keeps apical preparation small = Better tactile awareness is achieved Gradual taper = Ability to prepare proper apical stop is achieved
Match the following disadvantages with the correct description in the step-back technique:
Chances of pushing debris = It has a tendency to straighten the curved canal Time consuming = Debris may be pushed into periradicular tissues Difficulty in inserting instruments = It is a time-consuming process Straightening the curved canal = Difficulty may be encountered in inserting instruments
Match the following types of step-back technique with the correct description:
Modified Step-Back Technique = Preparation is completed in apical third of the canal Passive Step-Back Technique = Provides gradual enlargement of the root in an apical to coronal direction
Match the following descriptions with the correct type of step-back technique:
Started 2-3 mm short of minor diameter = Modified Step-Back Technique Provides gradual enlargement of the root = Passive Step-Back Technique Combination of hand and rotary instruments = Passive Step-Back Technique Almost parallel retention form is achieved = Modified Step-Back Technique
Match the following benefits with the correct type of step-back technique:
Gradual enlargement of the root = Passive Step-Back Technique Reducing the occurrence of procedural errors = Passive Step-Back Technique Retains the original shape of the canal = Modified Step-Back Technique Provides better tactile awareness = Modified Step-Back Technique
Match the following descriptions with the correct characteristic of step-back technique:
Time consuming = Disadvantage of step-back technique Gradual taper = Advantage of step-back technique Keeps apical preparation small = Advantage of step-back technique Irrigate often = Thing to remember during step-back technique
Match the following things to remember with the correct description in the step-back technique:
Work in a wet field = Irrigate often during the procedure Recapitulate often = Check the progress of the procedure frequently Irrigate often = Work in a wet field during the procedure Always work in a wet field = Recapitulate often during the procedure
Match the following descriptions with the correct type of step-back technique:
Two types of step-back technique = Modified and Passive Step-Back Technique One type of step-back technique = Passive Step-Back Technique Three types of step-back technique = Modified, Passive and another type of step-back technique
Match the following procedural errors with the correct type of step-back technique:
Transportation of the canal = Error that can be reduced by using Passive Step-Back Technique Ledge formation = Error that can be reduced by using Passive Step-Back Technique Zip formation = Error that can be reduced by using Passive Step-Back Technique Pushing debris into periradicular tissues = Error that can be reduced by using Modified Step-Back Technique
Understand the step-back technique in endodontics, its importance, and how it's used in root canal preparation. Learn about the gradual taper coronally and the preparation of the apical, middle, and coronal thirds of the canal.
