Masticatory ability is an essential factor for sustaining quality of life and social and systemic well-being, particularly in elderly.
Hence, early diagnosis and providing proper intervention for masticatory dysfunction is critical for preventing systemic frailty and establishing healthy aging. Several methods have been proposed to evaluate the objective masticatory function and the subjective masticatory satisfaction. Moreover, many previous studies reported the effects of diverse types of intervention for masticatory dysfunction. The aim of this study was to review some of the previously reported tests for evaluating masticatory function and intervention modalities.
