Abstract

summary Chewing efficiency may affect nutritional status in the elderly. Many elderly patients are complete denture wearers, and often present cognitive problems. Those two factors make evaluation of mastication difficult with experimental methods. Analysis of video recording may be a simple way to routinely assess chewing parameters. This study aimed at validating several parameters of video evaluation versus electromyography (EMG), which is considered the ‘gold standard’. The design was a prospective randomized study, carried out at the Faculty of Dentistry, University of Auvergne, Clermont‐Ferrand, France. Twelve complete denture wearers chewed four model foods differing in hardness. Sessions were videotaped and EMG recordings were registered. Mastication time, number of masticatory cycles and cleaning time were recorded simultaneously by video and EMG. Two investigators independently analyzed the videos twice, in random order. Evaluation of criterion validity: a positive video/EMG correlation was found for the parameters ‘chewing time’ (0·89, Pearson) and ‘number of masticatory cycles’ (0·94, Spearman), whereas no statistical difference was found between these two EMG and video variables (t‐test). Inter and intra‐rater reliability gave a positive intraclass coefficient (ICC) for duration of mastication (0·86–0·98), number of masticatory cycles (0·90–0·97) and cleaning time (0·90–0·98). Discriminatory ability was studied using anova (P = 0·01): variation was significant in masticatory duration (F = 10), number of masticatory cycles (F = 10) and cleaning time (F = 4). Video may be a useful assessment tool in prosthetic rehabilitation and can be applied to help choose the type of food (solid, semi‐liquid or liquid) to administer to dependent persons, particularly those suffering from dementia.
