Study Notes
Classification of Cavity Preparation
- International Caries Detection and Assessment System (ICDAS) is a classification system for cavity preparation.
- Mount and Hume's Si.Sta classification is another classification system for cavity preparation.
- Important concepts in cavity preparation:
- External line angle
- Internal line angle
- Point angle
- Cavosurface angle: the angle of tooth structure formed by the junction of a prepared wall and the external surface of the tooth.
Operative Dentistry
- Scope of operative dentistry: deals with the coronal part of the tooth.
- Objectives of operative dentistry:
- Eliminate disease
- Inhibit progress
- Prevent recurrence
- Restore the tooth to normal biomechanical and esthetic functions.
- Operative dentistry is not just "drill and fill", but includes a program for control of attacking mechanism.
- Ultimate goal: restoration of the masticatory system to normal health, functional efficiency, and harmonious esthetics.
Instruments Used in Operative Dentistry
- Dental explorer
- Periodontal (graded) probe
- Round bur (low speed, sizes 0.5, 1)
- Inverted cone bur (low speed, sizes 0.5, 1)
- Fissure bur (low speed, sizes 0.5, 1)
This quiz covers the scope and objectives of operative dentistry, emphasizing the importance of learning from mistakes and employing critical thinking skills. It refers to the textbook 'Art and Science 5th edition' for some exam questions.
