Abstract
Cone-beam computed tomography and
clinical examinations including pulp vital testing and pocket probing
depth showed a cemental tear with a severe labial alveolar bony defect,
but no endodontic lesions in #25, which had a sinus tract at the labial
site, in a 75-year-old woman. This
cemental tear was diagnosed as Class 3/Stage C based on the
classification by Lee et al., 2021. Recombinant human fibroblast growth
factor-2 as a regenerative agent was then applied into the bone defect
after removing cemental fragments and inflamed granulomatous tissue
containing bacterial colonies. The labial bone defect was regenerated to
the position of the crest of lingual bone, showing successful clinical
and radiographic outcomes at 2-year follow-up.
