UNCOMMON PRESENTATION OF A LONG-STANDING CALCIFYING FIBROBLASTIC GRANULOMA IN THE POSTERIOR MANDIBLE A 14-year-old Malay female was referred in view of a five-year history of an enlarging swelling over her lower right teeth, causing a disturbance in eating, speaking, and reciting Quranic verses. Clinical examinations revealed a non-tender, pedunculated exophytic growth on the buccal site measuring approximately 1.3 cm x 1.5 cm and the lingual site approximately 2.9 cm x 2.5 cm in size. The lesion encompassed her right mandibular first molar and second premolars with pinkish-red overlying mucosa and ulcerations on the lingual and occlusal aspects of the swelling. The right mandibular first molar had grade I mobility and 5 mm periodontal pocket depth associated with grade I furcation involvement. Deep scaling was performed on the involved area, and the excisional biopsy was performed under general anaesthesia. Histopathological examination revealed cellular connective tissue with focal calcifications, which gave a final diagnosis of Calcifying Fibroblastic Granuloma (CFG). The patient had an evaluation for oral hygiene maintenance and phase I periodontal treatment, which included deep scaling and a prescription for chlorhexidine mouthwash. No recurrence was observed one year post-operatively.
