The use of enamel matrix protein in the treatment of localized aggressive periodontitis: a case report.

The previously named localized juvenile periodontitis (LJP), recently reclassified as localized aggressive periodontitis (LAP) seen in young people, is a rare condition characterized by severe periodontal destruction around first molars and incisors in individuals with little or no accumulation of visible plaque and/or calculus. Treatment of this condition has traditionally included periodontal surgery and adjunctive antibiotic therapy. Even though several periodontal regeneration techniques in these patients have been reported, there have been no reports of the use of the enamel matrix proteins in the treatment of intrabony defects caused by this disease. This report describes the case of a 15-year-old patient who was diagnosed as having LAP and the resulting treatment and outcome. The treatment consisted of systemic antibiotic therapy and periodontal surgical procedures combined with enamel matrix protein application. The 6-month clinical probing and attachment level measurements and radiographic findings are reported.

Regression of cyclosporia-induced gingival overgrowth upon interruption of drug therapy.

Immunosuppressive therapy with cyclosporin has been known to cause gingival overgrowth in humans. It usually is not feasible to suspend this therapy to treat the adverse side effect. This case report describes a renal transplant patient who had used both cyclosporin and nifedipine for more than 10 years but had to discontinue immunosuppressive drug therapy due to organ rejection. Discontinuing therapy led to almost complete regression of the gingival overgrowth in a few months after interruption of cyclosporin therapy only. These findings suggest that the discontinuation of cyclosporin results in the reversal of gingival overgrowth without surgical intervention and may be the most definitive form of therapy for this condition in susceptible individuals as new drugs become available.
