This scientifc abstract aims to present a case of Peripheral Cemento-Ossifying Fibroma (PCOF) in a 19 years old female patient, emphasizing the clinical and histopathological features, differential diagnosis, and successful management of the condition.. Sympthoms: A 19 years old female patient presented with gingival enlargement around a fractured left first premolar. According to the dental history from the patient, gingival enlargement increased from the last 3 months to the date of admission to the clinic. Differntial diagnoses included irritational fibroma, pyogenic granuloma, and peripheral giant cell granuloma have been considered. Method: After a detailed clinical examination and radiographic assessment, non-surgical periodontal therapy was performed. An excisional biopsy was conducted to examine the specimen for histopathology. Peripheral Cemento-Ossifying Fibroma was diagnosed by the oral pathology lab through histopathological analysis. Follow-up examination after 3 weeks revealed improvement in the health of the gingival tissue surrounding the fractured tooth. In the interest of definitive treatment, the affected tooth was subsequently extracted. Conclusion: This case showcases the importance of thorough evaluation in diagnosing gingival enlargements. Acurate diagnosis, aided by pathology, led to effective treatment and recovery. This presentation serves as a valuable addition to the existing literature on PCOF and encourages further research into its etiology, pathogenesis, and treatment modalities.
