RESUMO
OBJECTIVES: To test if leptin can be detected in the gingival crevicular fluid (GCF) around moving teeth, and to determine whether any changes occur during orthodontic tooth movement. MATERIALS AND METHODS: An upper canine requiring distal movement served as the test tooth; the contralateral canine was used as a control tooth. The control tooth was included in the orthodontic appliance, but was not subjected to the orthodontic force. GCF sampling from the distal sites of the test and control teeth was done at baseline, 1 hour, 24 hours, and 168 hours. RESULTS: Leptin concentrations of the test teeth decreased in a time-dependent manner. When compared with the baseline measurement, the decrease was significant at 168 hours (P < .05). CONCLUSIONS: The concentration of leptin in GCF is decreased by orthodontic tooth movement; the results of the present study also suggest that leptin may have been one of the mediators responsible for orthodontic tooth movement.

Acute streptococcal gingivitis is an acute inflammation of the oral mucosa and also may be seen with the other oral diseases as aggressive periodontitis that is characterized by a considerable attachment loss over a relatively short period of time. Streptococcal infections of gingiva are seen rarely; also the origin of this gingival inflammation is occasionally different from that of routine plaque-associated gingivitis. The clinical features and treatment methods of these diseases are already reported in previous literatures. This case report describes a patient who presented with severe gingival inflammation and attachment loss that was diagnosed as an acute streptococcal infection associated with aggressive periodontitis. In this study a supportive treatment option was demonstrated based on these data and antacid treatment as adjunctive to the recommended treatment modalities was used for streptococcal gingivitis.
