Different Treatment Modalities for Vital Pulp of Immature Permanent Molars.

Objectives: To compare and asses apexogenesis results in young, immature permanent molars following pulpotomy using calcium hydroxide (CH), mineral trioxide aggregate (MTA), laser and laser assisted with MTA.
Methods: One hundred carious immature permanent molars indicated for pulpotomy in children aged 6-9 years old were allocated at random to four even groups (n=25) CH group; MTA group; laser group and laser assisted MTA group. With follow-up intervals of 6 and 12 months, the patients had clinical and radiographic assessments using digital periapical radiography. The outcomes were compared using the Anova and Monte Carlo tests.
Results: Throughout the 12-month follow-up period, no statistically significant difference was seen between the groups. The clinical evaluation at 12 months revealed success rates of 98, 98, 100, and 100% for the CH, MTA, laser, and laser assisted MTA groups, respectively. The assessment of the radiographic changes of the root foramen diameter between 0 and 12 months was highest for Laser assisted MTA group (44.1%) followed by Laser Group (38.4%), MTA (35.7%) and the least for CH group (21.8%).
Conclusions: Laser and laser combined with MTA pulpotomy techniques can be used as better substitutes for CH and MTA in pulpotomy of immature permanent molars.
