INTRODUCTION
Preparing a tooth to receive a restorative
material is a comprehensive endeavor. As
routine or mundane as it may seem, many
factors affect the appropriate tooth
preparation design for a given tooth. These
factors must be considered for each
restorative procedure contemplated, the
end result being that no two preparations
are the same.

Determination of cavosurface angle


Enamel margin strength


Direction of enamel rods


Cavosurface design in amalgam

CONCLUSION
 proper tooth preparation is accomplished
through systematic procedures based on
definite physical and mechanical
principles. Moreover, the physical
properties and capabilities of the different
restorative materials must be appreciated.
All of these are determining factors in
understanding proper tooth preparation.


CONCLUSION…..
 Without this background knowledge, plus
additional information concerning the
mechanics of cutting and patient
management, the exercise of proper
judgment for efficient and proper tooth
preparation cannot be achieved .If the
principles of tooth preparation are
followed, the success of any restoration is
greatly achieved
