Abstract
Objective: The objective of this study was to determine the most suitable material for indirect
pulp treatment (IPT) clinically and to determine the thickness (in mm) and type of tissue in
terms of radiodensity (in Hounsfield units [HU]) formed after pulp capping using cone‑beam
computed tomography (CBCT) scan.
Materials and Methods: A longitudinal interventional single‑blind randomized clinical trial
was conducted on 94 children (7–12 years) with a deep carious lesion in one or more primary
second molar and permanent first molar without the history of spontaneous pain indicated
for indirect pulp capping (IPC) procedure. About 109 teeth were treated using three materials,
namely, calcium hydroxide (setting type), glass ionomer cement (Type VII), and mineral trioxide
aggregate randomly. The teeth were followed up at an interval of 8 weeks, 6 months, and 1 year
for success of IPT as per the American Academy of Pediatric Dentistry clinical criteria. For
determining the thickness and type of dentin tissue formed, a CBCT scan was done immediately
postoperative and another scan at an interval of 6 months. The scans were compared to evaluate
the average thickness of the dentin bridge formed.
Results and Conclusions: Success rate for IPC was 96.85%. A significant difference was
obtained in the average thickness of reparative dentin at immediate postoperative and 6‑month
postoperative values in all three groups suggesting distinct barrier formation. Similar significant
findings were obtained in radiodensity of barrier formed (in HU). All three materials were found
to be equally suitable as IPC agents suggesting mineral gain.
