title: Endodontic Treatment of Primary Molars with Antibiotic Paste: A Report of 38 Cases.
abstract: OBJECTIVE
  This study presents 38 cases of primary molars with necrotic pulps treated with antibiotics-based paste.
  
  
  METHODS
  The technique consisted of necrotic tissue removal of the pulp chamber, using spoons excavators and low speed drills. Pulp cavity was washed with saline solution and dried with sterile cotton balls. Then an antibiotic paste composed of chloramphenicol, tetracycline, zinc oxide and eugenol - CTZ paste - was inserted at the entrance of root canals. Patients were evaluated clinically and radiographically at different times. The criteria that defined clinical success were the lack of periapical abscess and mobility compatible with chronological age. Radiographic assessments consisted in absence of radiolucency in the region of root bifurcation and pathological bone resorption.
  
  
  CONCLUSIONS
  There were 100% and 93% of clinical and radiographic success, respectively. The results suggest that the CTZ paste is an optional therapy for pulp of primary molars.
