📃 PREPARATION CONCEPT ❗️
Proper tooth preparation is accomplished through systematic procedures based on specific physical and mechanical principles. A prerequisite for understanding tooth preparation is knowledge of the anatomy of each tooth and its related parts. A mental image of the individual tooth being prepared must be visualized. The direction of the enamel rods, the thickness of enamel and dentin, the size and position of the pulp, the relationship of the tooth to its supporting tissues, and other factors all must be considered to facilitate appropriate tooth preparation.
There are important factors to successful clinical outcome :-
