Hydroxyapatite Postsurgical Bone Defect Filling: A Case Report

The cyst-like lesions are an important part of oral pathology, not only its frequency but also because many of them are specific in this region, derived from the remaining embryonic elements after tooth development. Odontogenic cysts are characterized by cavity lined with epithelium and a capsule containing tissue connective; periapical cyst is one of the most frequent lesions resulting from chronic infection and necrosis of the pulp organ. These lesions cause irreversible damage to bone tissue, which repair is a slow process that not always leads to complete healing of bone defect. Hydroxyapatite is the major component of vertebrates bone and dental tissues, therefore hydroxyapatite-based biomaterials do not cause significant immune reaction significant when implanted in the body. Objective: demonstrate the effectiveness of hydroxyapatite (Apafill-G) osteoconductivity and promotion of bone defects regeneration. Methodology: A case of a 32 years old male patient is reported, whose routine radiographic examination revealed a maxillary periapical cyst-like lesion associated with the upper central incisor, which was surgically treated filling the defect with Apafill-G (0.4 mm-0.6mm), suture with tissue adhesive (Tisuacryl®), and postoperative clinical and radiographic controls (72 hours, 7 days, 1 month). Results: Radiografic evaluation of patient, showed that the density of the implanted material covered 80% of the defect. At the clinical evaluation, mucosa sutured with Tisuacryl® showed low inflammation, mild erythema, little accumulation of bacterial plaque, oral fluids and good healing. Conclusions: We obtained excellent results in clinical and radiographic evaluation of the surgically treated patient, demonstrating the high biocompatibility and biofunctionability of the biomaterials used in the reported case.
