Calcium Sulfate as Bone Replacement Graft in Management of Localized Aggressive Periodontitis: A One-year Follow-up Report.

We report a case of localized aggressive periodontitis (LAP), which occurred during fixed orthodontic treatment in a 16-year-old African-American female patient. Oral hygiene instruction, removal of orthodontic bands and nonsurgical periodontal therapy were followed by surgical treatment of multiple sites using calcium sulfate as a synthetic bone graft material and collagen membrane as a barrier to achieve guided tissue regeneration. One-year follow-up of the case demonstrated that use of calcium sulfate as a synthetic bone substitute may provide favorable outcome in LAP patients. Furthermore, LAP patients undergoing orthodontic treatment can be managed successfully without tooth morbidity.
