Class II cavity preparations in primary molars p y

Two class II “ back‐to‐back” b k” cavities ii can be prepared as
essentially one procedure rather than separately.
Prepare the occlusal portion of each tooth then form
the proximal boxes vertically simultaneously by moving
the burs back and forth between the 2 proximal
surfaces establishing first the buccal walls then the
lingual or (vice verse).
It must be remembered that the axial wall on a first
primary molar will be slightly deep than on the
adjacent second primary molar. Etblihb Establish both gingival
i walls by perpendicularly the bur to round them.
