Oral microbiota profile of individuals stratified by N-BP exposure and history of N-BP-associated osteonecrosis of the jaw (ONJ). a At the phylum level, Firmicutes (59.02%) and Proteobacteria (24.27%) were the most prominent oral bacterial communities, followed by Bacteroidetes (7.82%), Actinobacteria (5.21%), Fusobacteria (2.35%) and TM7 (1.04%), an uncultured candidate division. The remaining phyla were <1% of the composite communities. b At the level of genera, Streptococcus (43.11%), Haemophilus (13.29%), Veillonella (12.68%), Neisseria (6.49%), Prevotella (4.28%), Rothia (3.21%) and unclassified Prevotellaceae (2.55%) were the most abundant genera, with the remainder having <2.5% average abundance. Variations in the composition of the oral microbiome between groups were not statistically different.
