Abstract
Introduction
The aim of this experimental study was to assess the outcome of direct pulp capping
with mineral trioxide aggregate (MTA) after complete excavation of caries in permanent
dentition with a 2-visit treatment protocol.
Methods
Sixty-four teeth with deep carious lesions were consecutively selected. The mean age
of the patients was 36.1 ± 15 years. An initial diagnosis of deep caries, with no
irreversible pulp involvement, was made. Excavation of caries was performed under
a rubber dam and operating microscope magnification. White MTA was applied, and a
provisional restoration was placed. At the following appointment, positive sensibility
testing and the MTA setting were confirmed. Bonded composite restorations were placed
afterward. The patient was recalled at least 1 year after treatment for clinical and
radiographic control. Outcome was described as success or failure. Success was defined
as lack of complaints from the patient, positive reaction to cold testing, no sensitivity
to percussion, and no widening of the periodontal ligament on the recall periapical
radiograph.
Results
Forty-six teeth (77.9%) were recalled after 3.6 years (standard deviation = 1.1 years).
The overall success rate was 91.3%. The success rate in occlusal caries was 100% and
89.7% in proximal caries (difference = 10.3%; 95% confidence interval [CI], 8.5–89.1).
The success rate in initial caries was 94.7% and 88.9% in secondary caries (difference
= 5.8%; 95% CI, −48.1 to 59.7). The success rate in patients younger than 40 years
was 100% and 80% in patients aged 40 years or older (difference = 20%; 95% CI, 4.2–35.8).
Conclusions
Direct pulp capping with MTA after pulp exposure during excavation of deep caries
could maintain pulp vitality in permanent teeth when a 2-visit treatment protocol
is observed.
