Abstract
BACKGROUND:Retrograde root filling is indicated when periapical inflammation cannot be resolved by conventional endodontic therapy. A retrograde filling should prevent flow of microorganisms and bacterial endotoxins from the root canal into periapical tissues.
The aim was to evaluate the clinical and radiographic treatment outcome of two different materials for retrograde root filling (dentin-bonded resin nano composite and glass ionomer cement) using special preparation performance of resection surface.
METHODS AND MATERIALS: Apicectomies of incisors and canines of 20 patients with indication of retrograde root filling were made. The entire resection surface was slightly concavely prepared. A total of 20 slightly concave root sections were divided into two groups of 10 individuals and filled with either root filling materials. This preparation technique prevents marginal contraction gaps during polymerization and makes a sealing of the entire resection surface possible. Controls were made after one, three, six and 12 months.
RESULTS: The last control made after 12 months shows that the proportion of successful cases was significantly higher in the first group with dentin-bonded resin nano composite group (64%)than in the second glass ionomer group (42%, p<0.001). The reason for failure in the second group was loosening of the retrograde filling.
CONCLUSIONS: Due to insufficient bonding strength to the concave resection surface, retrograde root filling with glass ionomer results in an unacceptably high failure rate. Dentin-bonded resin nano composite applied onto the entire, slightly concave resection surface is a feature apical filling material characterized by a high success rate.
