Abstract
Purpose: This study's purpose was to compare the clinical and radiographic success rates of 5.25 percent Sodium Hypochlorite (NaOCl) pulpotomies to Formocresol (FC) and Ferric Sulfate (FS) in decayed primary molars. Methods: Eighty-one primary molars, randomly divided
into three groups, were treated with one of three different pulpotomy materials; NaOCl, FC and FS. The outcomes of the different groups were assessed clinically and radiographically every six months over 18 months. Chi-square test was used to detect differences in outcome measures in all groups.
Results: At six months, clinical and radiographic success rates were 100 percent for each group (27/27). At 12 months, clinical success was 100 percent (24/24), 96 percent (24/25), and 95.7 percent (22/23) for NaOCl, FC, and FS respectively. The radiographic success was 95.8 percent
(23/24) for NaOCl group, and 100 percent for FC (25/25), and FS (23/23). At 18 months, the clinical success was 83.3 percent (20/24), 96 percent (24/25), and 87 percent (20/23) for NaOCL, FC, and FS respectively. The 18 month radiographic success was 91.7 percent (22/24), 100 percent (25/25),
and 95.7 percent (22/23) for NaOCl, FC, and FS respectively. No significant differences were found in clinical or radiographic outcomes between the three groups at six, 12 and 18 months. Conclusion: The three pulpotomy medicaments yielded similar outcomes.
