Association of Mixing Ability and Occlusal Support in Thai Elderly
Objectives: The purpose of this study was to investigate whether the mixing ability of older subjects was associated with varying degree of occlusal support.
Methods: The cross-sectional study was conducted on 109 independently living elderly aged 60 and over in Khon Kaen, Thailand. Dentate participants without denture replacement were recruited. Mixing ability was firstly measured using a two-color chewing gum mixing ability test with 20 chewing cycles and secondly determined the variance of hue (VOH) with the ViewGum software; inadequate mixing presents with larger VOH. A calibrated dentist recorded the oral status and class of occlusal support according to Eichner index. A structured questionnaire was used to obtain the information on demographics, medical history, and oral health behaviors. Multiple linear regression analysis was used to evaluate the association between mixing ability and occlusal support while controlling for possible confounders.
Results: The result indicated that mixing ability was associated with occlusal support according to Eichner index classification. (Beta, 1.04; 95% confidence interval, 1.02 to 1.06) after controlling for possible confounders.
Conclusions: This study suggested that mixing ability was associated with occlusal support according to Eichner index classification in the elderly.
