 # Most frequent site for dry socket is:
A. Upper molar area
B. Upper incisor area
C. Lower molar area
D. Lower incisor area

The correct answer is C. Lower molar area.

'Dry socket' derives its name from the fact that after the clot is lost the socket has a dry appearance because of the exposed bone. This condition is more common in women and tobacco users, and is most frequently associated with difficult or traumatic extractions and thus most commonly follows removal of an impacted mandibular third molar. In a series of 138 ‘dry sockets’ among 6,403 teeth extracted in human patients, Krogh reported that 95% were in lower bicuspid and molar sockets, and this is confirmed by most other large series of cases.
