Pulpotomy was beneficial for normal root development of immature traumatised teeth.

Indirect pulp capping, pulpotomy and apexification are three common endodontic treatments for immature traumatised incisors. They all affect tooth root development to some extent. This retrospective study compared the influence of these treatments on root development of immature permanent incisors following dental trauma. Twenty-one indirect pulp capping, 48 pulpotomy, and 58 apexification cases with a mean age of 8 years and median follow-up of 12 months were included. The apexification group had a lower trend towards apical closure than the other two groups. It showed thinner dentine wall thickness compared with the pulpotomy group. There was no significant difference between pulpotomy and indirect pulp capping in the trend to apical closure or dentine wall thickness. There was no significant difference in the variation of root length among the groups. Pulpotomy tended to form a normal apical constriction rather than a calcific barrier while apexification showed the opposite inclination. Indirect pulp capping had no specific inclination towards any type of apical closure.
