Abstract

The aim of this systematic review and meta-analysis was to summarize and to evaluate the available information on the effectiveness of oral exercises in improving oral functions in elderly. Electronic databases were searched from SCOPUS , PUBMED , CENTRAL , Thai Journals online , ClinicalTrials.gov , Thai clinical trials registry (TCTR) , Thai library integrated system (ThaiLIS) up to June 2021. We include randomized control trials (RCT) and quasi experimental study reporting effect of oral exercises on oral function. We assessed risk of bias by using Cochrane risk of bias tool for experimental studies. Eight studies were included. Studies were assessed risk of bias as unclear. There was a significant increase in the saliva flow rate (MD 0.17 mL/min; 95% CI 0.12 to 0.21; 3 studies; 176 participants). Not significant in anterior tongue strength (MD 0.88 kPa; 95% CI -5.64 to 7.39; p = 0.79; 2 studies; 132 participants). Not significant in posterior tongue strength (MD -0.93 kPa; 95% CI -9.29 to 7.44; p = 0.83; 2 studies; 132 participants). Not significant in lip strength (MD 1.04 kPa; 95% CI -4.46 to 6.54; p = 0.71; 1 study; 74 participants).

In conclusion, oral exercises have positive effect on oral function by increasing saliva flow rate. However, almost studies had uncleared risk of bias. Therefore, the results of this study cannot be conclusively concluded that oral exercise in the elderly improves oral function. More studies are needed.
