Correlation of mast cells in different stages of human periodontal diseases: Pilot study.

AIMS AND OBJECTIVES:The aim of this study was to evaluate and correlate the relationship between mast cells counts and different stages of human periodontal diseases. MATERIALS AND METHODS:The study sample comprised 50 patients, which were divided into three groups, consisting of 10 cases of clinically healthy gingival tissues (control group) 20 cases of dental plaque-induced gingivitis with no attachment loss and 20 cases of localized chronic periodontitis (LCP) characterized by the loss of periodontal support. The samples for control group were obtained during tooth extractions for orthodontic reasons. The specimens were immediately fixed in 10% neutral buffered formalin. CONCLUSION:In this study, LCP cases had higher mast cell counts compared to gingivitis sites or healthy tissues. Increased mast cell counts in the progressing sites of periodontal diseases may indicate the importance of these cells in the progression of chronic periodontitis.
