The conserative treatment of the necrotic and infected primary molars is often necessary in order to avoid extractions which may lead toinability to masticate or loss of space and subsequent problems concerning the development of the occl usion in the permanent dentition.
The purpose of this study was to evaluate the clinical significance of the conservative treatment of the infected primary molarss with necrotic pulps employing the formocresol pulpotomy technique same as in vital teeth and surgical intervention in the cases with a parulis, fistula or cellulitis.
The materials consisted of 25 primary molars of 9 boys and 4 girls ranging in age from 4 to 7 years. This study included clinical and radiographic observation at 3-month intervals postoperatively.
The following results were obtained.
1. Clinically, 20 cases of 25 were successful, exhibiting no clinical problems such as fistula, mobility, toothache and tenderness to percussion, etc. 5 cases were regarded as failures.
2. Radiographiclly, 14 cases revealed normal features, in 6 cases slight rarefa
ction was observed in the periapical and interradicular region, and marked periapical and interradicular rarefaction was observed in 5 cases.
3. Marked-´bony deposition was observed in the periapicaland interradicular,
regions in all the remainder except for 5 failurese. 4. Pathologic root resorption was observed in 2 cases.
