Healing of furcation perforations in primate teeth after repair with decalcified freeze-dried bone: A longitudinal study

Perforation repair with mineral trioxide aggregate: a modified matrix concept

“…The modified internal matrix concept uses, in contrast to other treatment concepts (Lemon 1992, Hartwell & England 1993, Bogaerts 1999), collagen as a completely resorbable barrier material and MTA for sealing of the perforation. This not only results in repair of the defect, but also promotes healing of the periodontal ligament as shown by the cases.…”

“…An intracanal approach is preferred, potentially eliminating the need for a surgical approach or intentional replantation (6). Numerous perforation repair materials have been used including indium foil, guttapercha, amalgam, calcium hydroxide, EBA, IRM, demineralized freeze-dried bone, and Cavit with mixed results because of physiologic compatibility and ability to seal (3,(7)(8)(9)(10). Like root-end filling materials, perforation repair materials should be well tolerated by the periradicular tissues, be insoluble, adapt and adhere well to the preparation walls, promote healing and cementum repair, be easy to manipulate, be dimensionally stable, be radiopaque, and not be affected by the presence of moisture (11).…”

The Development of Carbonate-containing Apatite/Collagen Composite for Osteoconductive Apical Barrier Material

“…Gutta-percha also has become a common filling material used in root canals. In an effort to identify the best apical barrier material suitable for all situations, the efficiency of several materials has been evaluated including dentin chips (1,2), decalcified freeze-dried bone (DFDB) (3,4), true bone ceramic (TBC) (4), tricalcium phosphate (TCP) (5), hydroxyapatite (HAp) (6), and mineral trioxide aggregate (MTA) (7)(8)(9)(10)(11). However, there are a number of drawbacks to these materials, such as bacterial contamination, antigenicity, quantity of supply, lifetime of the material, separation of particles from the apical foramen, and difficulty in manipulating the materials.…”

“…To this end, [1] atelocollagen without antigenicity (21,22) was reconstituted, [2] apatite was deposited on the fibers using the enzymatic hydrolysis method (23)(24)(25), and [3] the entire fabrication and washing procedures were performed under controlled stirring.…”
