A systematic search of PubMed and Cochrane Library was conducted for studies published between January 2010 and December 2024. Of 4004 records screened, 47 met the inclusion criteria. The included studies comprised 28 cross-sectional studies, 18 prospective clinical studies, and one longitudinal observational study. Risk of bias was assessed using RoB 2 for randomised controlled trials, ROBINS-I for non-randomised interventional studies, and ROBINS-E for studies evaluating exposure effects.

Most studies reported reduced salivary flow, bite force, and masticatory performance in individuals with periodontitis, while many prospective studies described functional improvement after periodontal therapy. Meta-analyses showed that individuals with periodontitis had significantly lower salivary flow (Hedges' &lt;i&gt;g&lt;/i&gt; = −1.14, &lt;i&gt;p&lt;/i&gt; &lt; 0.001) and higher eating-related disability scores (Hedges' &lt;i&gt;g&lt;/i&gt; = 0.45, &lt;i&gt;p&lt;/i&gt; &lt; 0.001) than healthy controls. Periodontal therapy was associated with a significant increase in salivary flow (Hedges' &lt;i&gt;g&lt;/i&gt; = 0.41, &lt;i&gt;p&lt;/i&gt; = 0.043). An exploratory meta-analysis also suggested a reduction in eating-related disability after treatment (Hedges' &lt;i&gt;g&lt;/i&gt; = −0.34, &lt;i&gt;p&lt;/i&gt; = 0.005), although this finding should be interpreted cautiously because the pooled studies included different interventional designs.
