Major topic: Calcium Hydroxide vs Formocresol in primary pulpotomies
Type of Article: Prospective Study
Main Purpose: To compare light-cured calcium hydroxide with diluted formocresol for its success as a primary molar pulpotomy medicant
Overview of method of research: Twenty patients (thirty four pairs of teeth) were selected with at least two matching, asymptomatic, contralateral primary molars requiring vital pulpotomies. Matched teeth in each patient were randomized to receive either calcium hydroxide or Formocresol as a pulpotomy medicament. All teeth were placed with stainless steel crowns and followed clinically and radiographically for one year or greater. The radiographs were evaluated for signs of pathology.
Findings: Clinical success for calcium hydroxide and Formocresol at twelve months or less were similar at 94% success rate for calcium hydroxide and 97% for formocresol. Beyond twelve months, clinical success varied more with calcium hydroxide at 84% and formocresol at 97%. Overall combined success rates were lower for calcium hydroxide than for formocresol.
Key points/Summary: The visible light-cured form of calcium hydroxide does not result in improved clinical or radiographic findings as a primary tooth pulpotomy agent compared with formocresol. Calcium hydroxide does not seem to be a viable alternative to diluted formocresol as a pulpotomy agent.
Assessment of article: Study proves why nobody is using calcium hydroxide as a pulpotomy agent.
