Study Notes
Diagnostic Instruments
- Loupes are used for magnification from 2X-10X and have a light source to improve illumination.
- The caries detection instrument is used to detect proximal caries and tooth vitality.
- The thermal test is considered a sensitivity test and is performed without anesthesia using a hot instrument or gutta-percha cone in the cervical region.
Endodontic Instruments
- The apex locator is used for measuring lengths and detecting orifices of the canal during dental procedures.
- The Barbed broach is used for the total removal of the vital but inflamed pulp tissue as one unit.
Tooth Isolation
- The purpose of using rubber dams is to isolate the tooth during dental procedures.
Vitality Tests
- The cold test is used to determine tooth vitality by exposing the pulp to cold using ice sticks or ethyl chloride.
- In laser doppler flowmetry, the blood flow in the pulp determines whether the pulp is vital or non-vital.
Endodontic Techniques
- Ultrasonic tips are used in endodontics for effective cleaning and shaping of the root canal.
- The apex locator gives a reading or sound when the file reaches the apex of the root for tooth apex determination.
