Aim
To compare the clinical and radiographic efficacy of Biodentine™, ProRoot® White Mineral Trioxide Aggregate (WMTA) and Tempophore™ as pulpotomy medicaments in the treatment of carious primary molars.
Methodology
A
parallel design, randomised controlled trial was developed. Patients
above three years of age with carious primary teeth with vital pulps
without spontaneous pain or history of swelling were included. Fifty
eight patients (82 teeth) with a mean age of 4.79 ± 1.23 years were
included. The teeth were randomised, blinded and allocated to one of the
three groups (Biodentine™, ProRoot® WMTA or Tempophore™)
for pulpotomy treatment. All teeth were followed up clinically and
radiographically (after 6, 12 and 18 months) by two blinded calibrated
investigators. A generalised estimating equation (GEE), Wald chi-square
test and an intention to treat analysis (ITT) with ′last carried
forward′ approach was performed using Statistical Package for Social
Sciences v 21.0 (IBM Corp., Armonk, NK, USA).
Results
Forty
six patients and 69 teeth were available for follow up after 18 months.
Clinical success (radiographic success in parenthesis) was 95.24%
(94.4%), 100% (90.9%) and 95.65% (82.4%) in the Biodentine™, ProRoot® MTA and Tempophore™
groups respectively, but the difference was not significant. Pulp canal
obliteration was significantly different among the experimental groups
as the Biodentine™ group exhibited significantly more pulp canal obliteration when compared to the ProRoot® MTA group at 6 months (p = 0.008) and 18 months (p = 0.003).
Conclusions
After 18 months follow up, there was no significant difference between Biodentine™ in comparison to ProRoot® WMTA or Tempophore™.
