AN IN-VITRO STUDY OF FURCATION PERFORATION REPAIR USING CALCIUM-PHOSPHATE CEMENT

Furcation perforations created in the pulpal floors of 30 extracted hu man molars were repaired with either light-cured glass ionomer cement (GI), calcium phosphate cement (CPC), or light-cured glass ionomer cem ent placed over a CPC matrix (M). After the cement was set, the teeth were immersed in India Ink for 48 h, dried, and sectioned longitudinal ly. Dye penetration into the furcation repair was independently evalua ted by three board-certified endodontists. There was no significant di fference in the mean extent of dye leakage among the three experimenta l groups. The use of CPC, with its enhanced biocompatibility, potentia l for osteoconduction, and sealing ability, may improve the prognosis of teeth with furcation perforations.
