ABSTRACT
The radiographic diagnosis of typical Stafne bone cavity could be done easily with cyst-like round or oval radiolucency near the angle of the mandible, under mandibular canal with or without involving mandibular base, and no symptoms. However there are some atypical cases suggesting possible variations of this entity. We report a quite unusual case, where Stafne bone cavity was lastly included in the differential diagnosis list. Histological examination of salivary gland tissues confirmed the final diagnosis.

Objective The effect of oral L-Dopa on healing of the experimental mandibular defect of rabbits was studied.Method 52 rabbits were assigned randomly to experimental group and control group.After bone defect being made on mandible,rabbits had been given with L-Dopa in experimental group.Healing bone samples were adopted at 14,21,30,42,49 days after operation,observed x-ray and histological changes and calculated out the bone histomorphometric parameters.Results X-ray inspection indicated that bone defect of the experimental group had completed callus union from 30th day.But,a part of the defect of control group did not appear callus union radiologically.Histological examination had the same result.Bone histormorphometry examination exhibited that there was a significant difference between TBV of the experimental and the control group(P
