Abstract
BACKGROUND
Endodontic treatment of primary molars represents one of the challenges in pediatric dentistry. There is a lack of consensus in the literature about the endodontic techniques and filling paste for primary teeth with pulp necrosis.
AIM
To compare the effectiveness of the LSTR technique (lesion sterilization and tissue repair) with CTZ paste (chloramphenicol, tetracycline, zinc oxide and eugenol) and pulpectomy with ZOE paste (zinc oxide and eugenol) in the treatment of primary molars with pulp necrosis.
DESIGN
Eighty-eight primary molars with pulp necrosis from 70 children between the ages of 3 and 8 years were included. The teeth were randomized to the LSTR with CTZ paste group or pulpectomy with ZOE paste group. Clinical and radiographic evaluations were performed at 18, 24, 30 and 36 months.
RESULTS
At 36 months, clinical success was 86.4% in LSTR with CTZ paste and 90.9% in pulpectomy with ZOE paste (p = .45). Radiographic success was 43.2% in both groups (p = 1.00). The overall success was 40.9% in LSTR with CTZ paste and 43.2% in pulpectomy with ZOE paste (p = 1.00).
CONCLUSION
After 36 months of evaluation, the effectiveness of the LSTR technique with CTZ paste and pulpectomy with ZOE paste was similar for the treatment of primary molars with pulp necrosis.
