Use of mineral trioxide aggregate for repair of furcal perforations.

چکیده
The histologic response to intentional perforation in the furcations of 28 mandibular premolars in seven dogs was investigated. In half the teeth, the perforations were repaired immediately with either amalgam or mineral trioxide aggregate; in the rest the perforations were left open to salivary contamination before repair. All repaired perforations were left for 4 months before histologic examination of vertical sections through the site. In the immediately repaired group, all the amalgam specimens were associated with inflammation, whereas only one of six with mineral trioxide aggregate was; further, the five noninflamed mineral trioxide aggregate specimens had some cementum over the repair material. In the delayed group, all the amalgam specimens were associated with inflammation; in contrast only four of seven filled with the aggregate were inflamed. On the basis of these results, it appears that mineral trioxide aggregate is a far more suitable material than amalgam for perforation repair, particularly when used immediately after perforation.

Objective: Furcal perforation is an undesirable complication that may occur during root canal therapy and seriously compromises the prognosis of endodontic treatment. The prognosis of furcal perforation repair depends on the prevention of bacterial infection of the perforation site. Thus, use of a biocompatible material for complete sealing of the perforation site is critically important. Thi...

Furcal perforation is usually an undesired complication that can occur during preparation of endodontic access cavities or exploring canal orifice of multirooted teeth. Inadequacy of the repair materials has been a contributing factor to the poor outcome of repair procedures.

This study evaluated in vitro the effect of using the operating microscope on repairing furcation perforations using Vitrebond or mineral trioxide aggregate. Forty-six human molar teeth were mounted into a jig attached to a simulated jaw. The teeth were allocated randomly to four groups (n = 10). Furcal perforations were made in the teeth using an ISO 012 round bur in a slow-speed hand-piece. E...
