Internal Resorption

A 60-year-old man had buccal furca abscess at #14 with an unknown radiolucent lesion within the tooth five months earlier (Fig.1 *).  Now the tooth is sensitive to cold.  CBCT shows internal resorption involving the mesiobuccal and distobuccal roots (Fig.3,4 (axial section) *) with exits mesially (Fig.3 >) and buccally (Fig.2 ^).  There is periapical radiolucency of MB (Fig.3,7) with the thickened overlying sinus membrane (Fig.3,5,6 (*), as compared to that over the tooth #3 (Fig.6)).  Osteotomy will be established in the septum away from the lesion (Fig.8 red circle) and for 5 mm (Fig.5 (coronal section)).  He is a heavy bruxer, loosening Ketac-cemented unipost.  Use PRF to repair the defect associated with the MB lesion and sinus lift.
