Moraschini V, et al. - Researchers aimed to determine the link between asthma and periodontal disease, via a systematic review and meta-analysis. Evidence robustly indicated an association between asthma and periodontal disease.

Methods

• Researchers performed an electronic search without date or language restrictions in MEDLINE, Cochrane, Web of Science, and LILACS until May 2016.
• They also performed manual search and in the grey literature.
• The search process, data analysis, and quality assessment were performed by two independent reviewing authors.
• Prospective and retrospective cohort studies, case-controls, and randomized clinical trials were eligible to be included in this analysis.

Results

• As per data, the search and selection process yielded 21 studies, published between 1979 and 2017.
• In the meta-analysis, a statistically significant difference was demonstrated for the parameters of gingival bleeding, plaque index, and gingival index for asthmatic participants with P<0.0001, P<0.0001, and P= 0.0005, respectively.
