Masticatory performance in oral function assessment: Alternative methods (original) (raw)

Journal of Oral Rehabilitation

Abstract

BackgroundMasticatory function declines with age or disease, implicating a poor chewing efficiency and an often‐unconscious change for a less healthy, yet easy to chew diet. Timely screening of masticatory function may foster an early‐onset diagnosis and potential treatment. The aim of this study was to compare alternative diagnostic tools for masticatory function to a Jelly‐scan test.Materials and MethodsPatients aged 70 years and older who were hospitalised for rehabilitation were recruited for this study. A total of four different tests for masticatory function were administered. The Japanese Society of Gerodontology glucose extraction test (Jelly‐scan) was used as reference to compare a colour‐changing gum test (Gum1‐colour) as well as a mixing ability test with a visual (Gum2‐visual) and opto‐electronical (Gum2‐digital) analyses. Receiver operating characteristic (ROC) curves were used to establish the discriminative value, kappa‐values were used to estimate individual agreemen...
