Abstract
Abstract
Keywords: Dentin bridge formation, Direct pulp capping, Mineral Trioxide Aggregate,
TheraCal LC.
Aim: to clinically and radiographically evaluate Mineral Trioxide Aggregate and TheraCal
LC as direct pulp capping materials.
Materials and Methods: Twenty Male patients aged (17-35 years) with immediate
mechanical pulp exposure in lower molars were randomly divided into two equal groups
(n=10). Group1: Pulp exposures were capped using MTA. group 2: Pulp exposures were
capped using TheraCal LC. Immediately after direct pulp capping, a base-line digital
bitewing and periapical radiographs were taken. Clinical evaluation was performed at 1, 4,
12 and 24 weeks after direct pulp capping for presence/absence of spontaneous pain,
tenderness to percussion, draining sinuses and pulp response to thermal pulp vitality test.
At 24 weeks after direct pulp capping, digital periapical and bitewing radiographs were
taken. Digitalized bitewing radiographs were submitted to image analysis software to
measure changes in dentin thickness in comparison to the base-line bitewing radiographic
image. Digitalized preoperative and postoperative periapical radiographs were submitted to
the same software to evaluate changes in the width of periodontal ligament space.
Results: Clinically, all cases showed criteria of successful treatment except 3, 4 cases in
groups 1 and 2 respectively. Statistical analysis revealed no statistically significant
difference between both groups with p-value > 0.05. All of the thirteen cases that were
available for evaluation after 6 months showed dentin bridge formation. In MTA group,
the mean value of dentin bridge formed (1.856± 0.420 mm) was higher than in TheraCal
LC group (1.765 ± 0.436 mm) with no statistical significant difference (p-value = 0.710).
Changes in the width of periodontal ligament space were not significantly different
between both groups recording p-value > 0.05.
Conclusions: Clinically and radiographically, MTA and TheraCal LC are favourable
materials for direct pulp capping inducing adequate dentin bridge formation and minimal
widening of periodontal ligament space.
