Objective: The aim of the present study was to examine the efficacy of a resin-modified glass ionomer(Geristore® syringeable) to repair accidental furcal perforations occurring during root canal treatment in dogs. Materials and methods: Two beagle dogs (mean age and weight: 15 months and 13.8 kg respectively) with furcal perforations (2 mm x 3 mm) in the mandibular second premolars (P2) were included. Under general anesthesia, supragingival scaling was performed, performation sites were irrigated with 0.9% sodium hypochlorite and haemorrhage was controlled. Geristore® syringeable was delivered to the perforation site using intra-oral tips. The material was left over the perforation defect for ten seconds and then light-cured according to the manufacturers’ instructions. After 4 months, a periodontal examination was performed following which the animals were sacrificed. Jaw segments were prepared and histologically assessed for the presence or absence of hard tissue apposition in the furcal sites where Geristore® was placed. Results: Upon clinical examination, teeth with furcal perforations repaired with Geristore® presented with bleeding on probing, pus discharge and bone resorption. Histological results displayed severe gingival inflammation with chronic inflammatory infiltrate around the defect and absence of cementum repair. Conclusion: Within the limits of the present histological experiment, it is concluded that Geristore® is not advantageous for repairing furcal perforations occurring accidentally during endodontic treatment.
