TEMP is a ready-to-use bioceramic paste for intracanal dressing.
Microorganisms and their endotoxins are mainly responsible for the pathogenesis
of pulp and periapical infections. Consequently, one of the main objectives of endodontic
treatment is to eliminate microorganisms and their endotoxins in the most extensive and
effective way possible.
The use of mechanical preparation, followed by disinfection with chemical agents, is the
method used to succeed in the elimination of microorganisms. However, when the infection
is in the acute phase and the treatment cannot be performed in a single session, a delay
dressing is used between the sessions and the BIO-C
®
TEMP is the material of choice.
Until recently the Calcium Hydroxide paste was the only option used in temporary
disinfection procedures in endodontic treatment, however, this material has some limitations.
It is a material of difficult application and intracanal removal and, as a major disadvantage,
has high solubility in water (1.2 gL
-1
) that causes rapid dissolution in the medium, resulting in
limited clinical benefits.

TEMP has a great advantage over Calcium Hydroxide pastes because it presents
low solubility and thus allows the product to be in contact with the canal walls for a long
period of time. As a result, a high release of hydroxyl ions (OH
-
) is obtained in a continuous and
gradual way with the increase of the pH of the fluid surrounding the application. The increase
in pH plays an important role in preventing the proliferation of microorganisms through the
processes of protein denaturation and destabilization of the plasma membrane
