Description

TECHNICAL DESCRIPTION

This invention concerns new and biocompatible inorganic cement (OP3), for treatment and sealing of dental root canal after pulp removal. As its competitors, this cement can be easily spinned into the canal with a lentulo spiral and is radio-opaque as requested by norms. This cement presents also some major advantages over products actually marketed for these indications.

Compared with calcium hydroxide-based pastes or cements
– it has the same antimicrobial effect
– it releases strontium besides calcium ions for better apical plug induction
– it hardens in situ and is expansive (definitive material and not only temporary).

Compared with zinc oxide-eugenol-based cements (ZOE):
– besides instantaneous antimicrobial activity, it presents also a long term antimicrobial activity;
– It could also be used for treatment of periapical lesions;
– Its expansion properties allow better sealing water tightness without necessarily resorting to gutta-percha points.

INDUSTRIAL APPLICATIONS

The technology describes a new endodontic inorganic cement.
