INTRODUCTION: The association between the oral microbiome and periodontal diseases is still unclear. We performed a systematic review and meta-analysis to quantify the association between the specific pathogens and periodontitis.
EVIDENCE ACQUISITION: A computerized medical search was performed using MEDLINE and SCOPUS database between 1950 and May 2017 to identify all case-control studies that evaluated the association between specific pathogens and periodontitis. The pooled Odds Ratio with relative 95% confidence interval (95% CI) was calculated and plotted in the forest plot.
EVIDENCE SYNTHESIS: Eleven RCTs involving 2111 patients were included. The retrieved case-control studies evaluated the presence or absence of different targeted pathogens. Among the microrganisms evaluated Porphyromonas gengivalis (OR [95% CI] 2.93 [0.98,8.87]; P<0.0001) and Streptococcus mutans (OR [95% CI] 1.77 [0.89-3.54]; P=0.03) were found to be risk factors for the development of periodontitis, while Aggregatibacter actinomycetemcomitans (OR [95% CI] 0.52 [0.33-0.83]) played a protective role for periodontitis.
CONCLUSIONS: It seems that changes in the taxonomic composition of the microbiome rather than single targeted pathogens is the key determinant of periodontitis.
