Abstract

Background: Severity of gingivitis in young children is lower than in older children and young adults but histological characteristics have not been studied before. Purpose: To compare histological characteristics in dental plaque-induced gingivitis in children and adults and analyze them regarding inflammatory gingival response. Methods: 20 teeth with dental plaque-induced gingivitis from 10 7-to-10-year-old children and 10 18-to-25-year-old pa-tients with positive Ainamo & Bay gingival index were analyzed. Histologic analysis of teeth and gingiva cuts with light microscope was carried out. Data were analyzed with the Mann-Whitney and χ2 tests (p ≤ 0.05). Results: Oral epithelium from the coronal area was higher in children than in adults, which was statistically significant. The average gingival pocket depth was 2.4 ± 0.68 mm in children and 2.9 ± 0.44 mm in adults; differences were significant (p = 0.045). Thickness and number of layers of the junctional epithelium were higher in adults at the coronal end. 30% inflammatory cells were observed in children with predominance of neutrophil cells, while in adults the percentage was 40% with predominance of lymphocytes. Statistically significant differences were found between loose connective tissue in children and dense tissue and adults with a 70% frequency (p = 0.025). Conclusion: The few observed differences are not significant once the inflammatory lesion is established.
