Abstract
Purpose
To evaluate clinical and radiographic outcomes of vital pulp therapy (VPT) in deeply carious young permanent first molars (PFM) affected with MIH over 24 months.
Methods
In this prospective randomized clinical trial, n = 50 children with deeply carious young PFM affected with MIH, and diagnosed with reversible or irreversible pulpitis were randomized into 2 groups: indirect pulp treatment (IPT) and pulpotomy (partial or complete). Teeth were followed up clinically and radiographically for 24 months. Statistical analysis was done using Chi-square test; P ≤ 0.05 was considered significant.
Results
A total of n = 50 teeth/patients (n = 26 females (52%), n = 24 males (48%)) were included, and 14 upper and 36 lower PFM were treated. Mean age was 11 ± 3.2 years. Clinical and radiographic success rates were: 96% for IPT, 90% for PP and 82% for CP (and 86% for both types of pulpotomy combined) over 24 months. There were no significant differences in outcomes between treatment groups. Age, gender and tooth location/jaw were found to have no statistically significant difference in outcomes among treatment groups, nor did pulpal status or root maturity, regardless of type of VPT and follow up period.
Conclusions
VPT is a valid treatment option in deeply carious young permanent first molars affected with MIH over 24 months. IPT had a higher clinical and radiographic success rate (96%) than partial or cervical pulpotomy (total 86%), but the difference was not statistically significant. Future randomized clinical trials on VPT for teeth affected with MIH are recommended with larger sample size and longer follow-up.
