Aim and objective: To compare mineral trioxide aggregate (MTA) and calcium hydroxide as pulp capping agents for the success of coronal pulpotomy of carious, vital immature molars to maintain pulp vitality, and hence allow maturogenesis.
Materials and methods: Thirty immature carious pulpally involved vital molars were included for pulpotomy in a randomized clinical trial. The included molars were allotted into two groups according to the type of pulp capping material used: Group I (control group): calcium hydroxide group (15 molars) and group II (study group): MTA (15 molars) by chit method. The children were recalled for clinical evaluations after 1, 3, 6, and 9 and 12 months and radiographic examination was done at 6 and 12 months. Maturogenesis was assessed by Nolla\'s stages of root formation and quantitative analysis to assess maturogenesis was done three dimensionally (width, length and apical closure) by square grid radiographic method.
Results: The mean age of subjects was 9.06 ± 2.4 and 9.16 ± 2.55 years for the calcium hydroxide group and MTA, respectively (p = 0.918). The pulpotomy procedure was significantly successful (p < 0.0005) according to all parameters irrespective of the pulp capping agent used. Though MTA performed better in the amount of quantitatively measured dentino-pulpal complex, maturogenesis than calcium hydroxide but the difference was not statistically significant.
Conclusion: Our study concluded that the success of the pulpotomy procedure is not exclusively dependent on the supposed stimulatory effect of a particular type of medicament used but is directly related to the capacity of both dressing and definitive restorative material to provide a biological seal against immediate and long-term microleakage along with the entire restorative interface.
Clinical significance: The coronal seal is the most important clinical factor required to achieve pulpotomy goals in immature permanent carious molars.
