Maintenance after a complex orthoperio treatment in a case of generalized aggressive periodontitis: 7-year result

Abstract

Background: Generalized aggressive periodontitis (GAgP) encompasses a distinct type of periodontal disease exhibiting much more rapid periodontal tissue destruction than chronic periodontitis. The best method for management of GAgP may include the use of both regenerative periodontal techniques and the administration of systemic antibiotics.

Methods: The treatment of a case of GAgP over a period of 6.7 years is presented in this case report. Initial periodontal therapy (week 1- 32) consisted of supragingival plaque control and three appointments of scaling and root planing. Based on the periodontal pathogens isolated (5 species), the patient also received metronidazole plus amoxicillin for one week, followed 10 weeks later by metronidazole plus amoxicillin/clavulanate for one week. The patient was put on regular supportive periodontal therapy (SPT) thereafter. Orthodontic treatment was performed after completion of the initial therapy for 96 weeks. Measurements of clinical attachment level, bleeding on probing and plaque index were obtained at every examination.

Results: Antimicrobial and mechanical treatment resulted in eradication of all periopathogens and significantly improved all clinical parameters. During orthodontic treatment and active maintenance, there was no relapse of GAgP. The patient participated in SPT for 194 weeks and thereafter decided to discontinue SPT. Twenty-four months later a relapse of GAgP was diagnosed and all teeth had to be extracted.

Conclusions: These results indicate that a combined mechanical and antimicrobial treatment approach can lead to consistent resolution of GAgP. Further studies including a larger number of cases are warranted to validate these findings.
