After orthognathic surgery, postoperative complications are studied by many clincian.
The complications include sensory disturbance, jaw fracture, excessive bleeding, condylar
positional changes and loss of pulp vitality. Few surgical procedures are as satisfying
for the surgeon and patient as a well-done orthognathic surgery. On the other hand, the
patient is more satisfied with the result than patient overcome but it is not serious
complications. One of these, the problem about loss of pulp vitality can't influence
function but give a lot of discomfort to the patient.
From September 1997 to January 1998, 7 patients who are treated for dentofacial
deformity via Le Fort I osteotomy or anterior segmental osteotomy were examined pulp
sensitivity using digital pulp tester. This preliminary study have a focus on the
investigation of recovery of pulp vitality. The electric pulpal test were used at
preoperative. postoperative, at intervals. And we report some results acquired from this
study.
Follwing result are obtained
1. In anterior segmental ostetomy case (1 case), total 12 teeth were examined.
Postoperative 8 weeks, 1 tooth are positive reaction.
2. In Le Fort I osteotomy case (6 case), total 71 teeth were examined, Postoperative 8
