Abstract
Introduction
The
purpose of this study was to assess the long-term clinical outcomes of
direct pulp capping (DPC) with ProRoot MTA (Dentsply, Tulsa, OK) and
Endocem (Maruchi, Wonju, Korea) as pulp capping materials. To this end,
the 1-year cumulative successes of both materials were evaluated and
compared with those of the 3-month outcomes in a prospective, randomized
controlled trial.
Methods
Patients
were recruited from the Department of Conservative Dentistry of the
Yonsei University Dental Hospital, Seoul, South Korea, from January to
May 2013. Of the 48 teeth that met the inclusion criteria, 46 teeth were
randomly allocated to either ProRoot MTA or Endocem groups (
n = 23).
Direct pulp capping was performed, and clinical and radiographic
examinations were conducted over 1 year after the treatment. Survival
analyses were conducted to compare the cumulative successes between
ProRoot MTA and Endocem and to evaluate other clinical variables.
Results
Forty-one
teeth were recalled 1 year after the treatments (recall rate = 89.13%).
There were no significant differences between the cumulative successes
of ProRoot MTA and Endocem in either log-rank or Cox proportional hazard
regression analyses (
P > .05). Among the other clinical
variables, cavity type (class I, II, III vs class V) was determined to
be significant in both the log-rank test (
P = .001) and Cox regression analysis (
P = .006).
Conclusions
Both
ProRoot MTA and Endocem exhibited similar cumulative successes as
direct pulp capping materials up to 1 year. The teeth restored with
class V cavities exhibited significantly lower cumulative success rates
after direct pulp capping compared with the teeth restored with other
types of cavities.
