The purpose of this study was to evaluate the usefulness of Ga-67 scintigram in
predicting the disappearance of inflammatory activity in mandibular lesions of dogs.
Inflammatory bony lesions were produced artificially by the injection of sclerosing
solution and bacterial suspension through the distal root canals of the lower 4th
premolars in 10 dogs.
The serial Ga-67 scintigrams and periapical radiograms were obtained. After 3 to 6
weeks duration of antibiotic therapy, the experimental animals were killed, and the
mandibles were dissected. Bacteriologic culture and antibiotic sensitivity test were done,
The following results were obtained.
1. The negative Ga-67 scan has 100% predictive value, and is a strong evidence of
the resolution of inflammatory activity.
2. In 2 animals of positive Ga-67 scan, 1 animal had negative culture.
3. In 14 cases of positive Ga-67 scan, radiographically there was increase in the size
of lesion in 9 cases, no change in 5 cases .
4. In 8 cases of negative Ga-67 scan, radiographically there was increase in the size
of lesion in 1 case, no change in 6 cases and decrease in 1 case.
