Regeneración periodontal en lesión de furcación grado II con matriz derivada del esmalte. Reporte de caso clínico.

Introduction. Periodontal regeneration is defined histologically as the new formation of tooth-supporting tissues, which includes alveolar bone, periodontal ligament and cementum, on a previously lost root surface. The application of protein derivatives of the enamel-derived matrix (EDM) was introduced as an alternative to obtain periodontal regeneration, in furcation affectations and intraosseous periodontal defects. Furcation involvement is bone resorption in the bifurcation or trifurcation area of a multirooted tooth. Case report. 38-year-old, female patient, ASA I, who presented for consultation for a restoration change in OD 36. On clinical and radiographic examination revealed a grade II furcation defect according to Hamp, with loss of horizontal support > 3 mm, but without passing the probe and vertical probing depth < 3 mm at the vestibular and lingual midpoint, presence of bleeding on probing. Once the hygienic phase was completed, periodontally regeneration with EDM (Emdogain®). Reduction of a grade II furcation defect to grade I was achieved after six months, with radiographic bone filling in the furcation area and vertical and horizontal probing < 3 mm. Conclusions. Class II furcation defects are the most predictable to obtain complete furcation closure or Class II to I. [ABSTRACT FROM AUTHOR]
