Periodontal Regenerative Therapy with Recombinant Human Fibroblast Growth Factor-2 and Deproteinized Bovine Bone Mineral in Patient with Chronic Periodontitis: An 18-month Follow-up Report.

Abstract

This report describes a case of generalized chronic periodontitis requiring periodontal regenerative therapy. The patient was a 62-year-old man who presented with the chief complaint of gingival swelling in the molar region. An initial examination revealed that 31.6% of sites had a probing depth of ≥4 mm and 18.5% bleeding on probing. Radiographic examination revealed vertical bone resorption in #14, 25, 26, 27, 32, 37, 45, and 47, and horizontal resorption in other regions. Based on a clinical diagnosis of moderate chronic periodontitis, initial periodontal therapy consisting of plaque control and scaling and root planing was performed. Occlusal adjustment of premature contact sites was performed after inflammation was suppressed. Surgical periodontal therapy was subsequently performed at selected sites. Periodontal regenerative therapy using recombinant human fibroblast growth factor (rhFGF)-2 was performed on #14, 25, 26, 32, and 37. Combination therapy with rhFGF-2 and deproteinized bovine bone mineral (DBBM) was performed on #45 and 47. Other sites with residual periodontal pockets were treated by open flap debridement, and #27 was extracted due to a bone defect exceeding the root apex. Progress was then reevaluated and the patient placed on supportive periodontal therapy. Periodontal regenerative therapy using rhFGF-2 in combination with DBBM resulted in an improvement in clinical parameters and vertical bone resorption. This improvement has been adequately maintained over an 18-month period. The periodontal treatment provided resulted in a marked improvement in the patient's oral health-related quality of life.
