Abstract
The aim of this study was to evaluate and compare the clinical and radiographic success rates of pulpotomies in primary molars using a new stain-free tricalcium silicate cement (Bio-C Pulpo) versus a conventional white MTA (MTA Angelus) as a pulpotomy medicament for primary teeth. Seventy primary teeth in 33 patients were randomly divided into two groups, MTA Angelus (n = 34) and Bio-C Pulpo (n = 36). Clinical and radiographic follow-up examinations were conducted at seven days (except radiographic follow-up), and at one, three, six and 12 months. At 12 months, the clinical success rate of the MTA Angelus group was 100 percent (28 out of 28), and the radiographic success rate was 100 percent (28 out of 28). In comparison, the clinical success rate for the Bio-C Pulpo group was 100 percent (29 out of 29), and the radiographic success rate was 100 percent (29 out of 29). No significant differences were found between the groups at any follow-up evaluation. According to Fisher´s exact test, a significant difference was observed between the pulpotomy agent and tooth discoloration (p < 0.001). The success rates were 100% for the Bio-C Pulpo group, with no case of discoloration, and 10.31% for the MTA Angelus group. Both MTA Angelus and Bio-C Pulp pulpotomy medicaments are appropriate options for pulpotomies in primary teeth, and enable high clinical and radiographic success rates. However, more long-term studies are required to test the new Bio-C Pulpo medicament.
Highlights
Untreated carious lesion in deciduous teeth was the 10th most prevalent condition globally, and affected 621 million children worldwide[1] in 2010, as pointed out by the Global Burden of Disease (2015)
Seventy pulpotomies were performed in the primary molars of 33 children (15 females, 18 males) with a mean age and standard deviation of 5.7 ± 1.6 years
In the Bio-C Pulpo group, one tooth was excluded at the 3-month follow-up due to disease, one tooth was excluded at the 6-month follow-up because the participant moved away, and four teeth were excluded at the12-month follow-up because the participant did not show up for the return visit
Summary
Untreated carious lesion in deciduous teeth was the 10th most prevalent condition globally, and affected 621 million children worldwide[1] in 2010, as pointed out by the Global Burden of Disease (2015). Pulpotomy is the most common treatment for carious-exposed pulps in asymptomatic primary molars This procedure aims to maintain radicular pulp vitality or to heal the diseased coronal pulp after amputation.[2,3,4] Studies comparing mineral trioxide aggregate (MTA) versus formocresol (FC) in pulpotomies of deciduous teeth attest that the latter presents superior or similar clinical and radiographic performance.[3,5,6] MTA was introduced by Torabinejad in 1993.
