Afterwards many studies have demonstrated MTA to be a predictable pulp capping
material.3,4 MTA elicits dentinal bridge induction faster than CaOH, resulting in pulpal healing and high success rates in clinical procedures.2-3,6
On the first day after pulp capping
with Ca[(OH).sub.2], the cavity floor was densely filled by scattered granular structures overlying a proliferation of the normal cellular zone of the pulp (Table 1).
Where removal of all dental caries would lead to a small pulp exposure, 9/14 taught indirect pulp capping
, the remainder teaching the student to perform a vital pulpotomy.
In 1995 Mineral Trioxide Aggregate (MTA) was introduced as direct pulp capping
agent in Loma Lind University.
Direct pulp capping
is a treatment for exposed vital pulp involving the placement of a dental material over the exposed area to facilitate both the formation of protective barrier and the mainte- nance of vital pulp.
Direct pulp capping
is important to avoid more invasive and resource-intensive procedures of conventional root canal treatment.

The results of in vivo studies on dogs showed that as pulp capping
materials, MTA and CEM showed similar favorable biological outcomes, and both better than CH especially in terms of inducing the formation of the dentinal bridge (56).
Recently, a bioactive glass-incorporated light-curable pulp capping
material (pulp regenerative material, Activa[TM] Bioactive, Pulpdent, Watertown, MA, USA) has been introduced as the first bioactive dental product approved by the FDA in terms of bioactivity for indirect pulp capping
materials; it provides quick setting times of less than 20 s for clinical convenience and biomineralization ability for hard tissue regeneration, and it has excellent biocompatibility .
(1) These materials are largely used in endodontic treatments; however, they can also be used in restorative dentistry, including direct pulp capping
. (1, 2)
Therefore, the aim of the present study was to evaluate the in vivo histological dental pulp state after indirect pulp capping
using sildenafil or L-NAME, both incorporated into a new BTS.
