Association Between Masticatory Performance and Oral Condition Factors in Adults: a Systematic Review and Meta-Analysis
Objectives: To give an overview of the current evidence on the associations between oral condition factors and masticatory performance of adults, and to evaluate the direction and level of the associations.
Methods: Medline (PubMed), Embase (Ovid) and CINAHL Plus (EBSCOhost) were searched up to May 2021 for cross-sectional studies on oral conditions and masticatory performance in adults. Methodological quality of the included studies was independently evaluated based on Joanna Briggs Institute critical appraisal checklist for analytical cross-sectional studies. Data on the associations between oral condition factors and masticatory performance were extracted. Meta-analysis was conducted on the correlation coefficients and standard errors.
Results: Out of the 12,023 identified records, 73 articles reporting on 61 studies were included in the qualitative synthesis and 20 studies were included in the meta-analysis. Among the oral condition factors that had positive associations with masticatory performance, the number of natural/functional teeth was reported by the largest number of studies, followed by perioral muscle status, dental prosthetic status except the use of removable prosthesis, and oral moisture status. Wearing dentures and poor periodontal status showed negative associations with masticatory performance. Results of meta-analysis showed that the oral condition factor with the strongest level of positive association was the number of natural teeth (pooled correlation coefficient: 0.50, 95%CI: 0.47 to 0.53), followed by the number of functional teeth, maximum tongue force/pressure, denture quality, and the weakest association was oral moisturization (pooled correlation coefficient: 0.11, 95%CI: 0.06 to 0.15).
Conclusions: Number of natural/functional teeth, perioral muscle status, oral moisture status, dental prosthetic status and periodontal status are the main oral condition factors influencing masticatory performance. Among these factors, number of natural/functional teeth has the strongest positive association.
