ABSTRACT
Twelve puppies were used to study the effeciency of bone cement as a mean of fi ationofan induced mandibular fracture. It gave adequate fixation and complete bony union was evident within two months. The general condition of the dogs was satisfactory. The permanent tooth germ adjacent to the cement showed irrigularities both in shape and structure. The treatment of jaw fracture in chddren with such material should be carried our with caution. The absence of soft tissue break down on the cement encouragous its intraoral use but complete asepsis is mandatory.
