Abstract

Background: The aim of the present study was to evaluate the subgingival microbiome in patients with grade C molar‐incisor pattern periodontitis (C‐MIP) affecting the primary or permanent dentitions. Methods: DNA was isolated from subgingival biofilm samples from diseased and healthy sites from 45 C‐MIP patients and subjected to phylogenetic microarray analysis. C‐MIP sites were compared between children affected in the primary to those affected in the permanent dentitions. Within‐subject differences between C‐MIP‐affected sites and dentition‐matched healthy sites were also evaluated. Results: C‐MIP sites of subjects affected in the primary dentition showed partially overlapping but distinct microbial communities from C‐MIP permanent dentition sites (p < 0.05). Differences were due to increased levels in primary C‐MIP sites of certain species of the genera Capnocytophaga and Leptotrichia, while C‐MIP permanent dentition sites showed higher prevalence of Filifactor alocis. Aggregatibacter actinomycetemcomitans (Aa) was among species seen in high prevalence and levels in both primary and permanent C‐MIP sites. Moreover, both permanent and primary C‐MIP sites showed distinct microbial communities when compared to dentition‐matched healthy sites in the same subject (p < 0.01). Conclusions: Primary and permanent teeth with C‐MIP showed a dysbiotic microbiome, with children affected in the primary dentition showing a distinct profile from those affected in the permanent dentition. However, Aa was enriched in both primary and permanent diseased sites, confirming that this microorganism is implicated in C‐MIP in both dentitions. [ABSTRACT FROM AUTHOR]
