Antibiotic Paste as an Alternative Treatment for Pulp Necrosis: Case Reports

Abstract

Introduction: Dental caries is a disease that frequently affects children at an early age and is the main cause of pulp infections in primary teeth. The treatment for pulp pathologies, such as pulp
necrosis, aims to preserve the tooth in the oral cavity, which is a real challenge due to the anatomy of the canals.
For this reason, an alternative treatment emerges using a combination of three
broad-spectrum antibiotics without instrumentation. Case report: This study involves 7 patients aged between 5 and 8 years, diagnosed with pulp necrosis with dentoalveolar abscess in primary
molars. A pulpotomy was performed, and an antibiotic paste composed of three medications (ciprofloxacin 500 mg, metronidazole 500 mg, clindamycin 300 mg) in a propylene glycol
vehicle was applied as pulp therapy. The teeth were restored with resin-reinforced glass. After 8 days of treatment, an absence of symptoms was observed. Conclusion: The cases presented were successfully treated with this alternative treatment, thus allowing the tooth to remain in the mouth healthy and functional.
