Use of radiography in endodontics Radiographs play an important role in the diagnosis during various treatment steps and • evaluation of the success or failure of treatment.
The radiographs help in identifying the lesion whether it is pulpal, periapical, periodontal or bony lesions
To locate pulp To determining the root and pulpal anatomy i.e. the number of roots/ root canals, unusual root morphologies, root curvatures, canal locations with respect to the pulp chamber, bifurcations/ trifurcations and calcifications To determine the root canal length before instumentations.
To determine any perforation or resorption of root and surrounding structure.
To estimate any abscess present at the tooth site
For complete evaluation and…show more content… This method is used to detect a pulpless tooth that is not noticeably discoloured and which shows a gross difference in translucency
Q. endodontic traid
A
Endodontic triad consisting of biomechanical preparation, microbial control and complete obturation of the canal space remains the basis of endodontic therapy
The ultimate goal of endodontic treatment is to create an environment in which the body can heal itself. Adequate access is the key to achieving this and, therefore, the key to achieving endodontic success.
Q. glass bead sterilizer
A
This is a method which is used for sterilizing the working ends of endodontic files and reamers by placing them in a container containing glass beads heated to approximately 225°C (437°F) for a defined period of time.
Glass bead sterilizer are not validated for virus infection control, so its validity is not proven
Disadvantages
Glass bead sterilizers are ineffective against prions
Only files are reamers can be sterilized
q. cold test a solid ice stick which is applied to facial surface of the tooth.
The stick is kept in contact for 5
