“…Four items related to the QOL have been reported to be as follows: behavioural competence, perceived quality of life, objective environment, and psychological well‐being ( Testa & Simonson, 1995). In our previous study, chewing ability was related to not only physical health but also to social health ( Miura, Araki & Umenai, 1997), and thus, in the present study, the PGC morale scale was used to evaluate subjective well‐being and/or life satisfaction. The Japanese version of this scale was developed by Maeda, Asano & Yaguchi (1979).…”

The present study statistically evaluates the relationship between chewing ability and quality of life (QOL) in elderly Japanese residents. We used a subjective evaluation and a mastication score determined by the food intake status to evaluate chewing ability. The PGC morale scale was used to evaluate the QOL level. The mastication score was significantly related to the QOL level in the subject group (P<0.05). The relationship between the subjective evaluation of chewing ability and the score on the PGC morale scale showed a similar tendency. In the section of the PGC morale scale that assesses agitation, attitude towards own aging, and lonely dissatisfaction, chewing ability was correlated with attitude toward own aging in particular (P<0.05). These results have suggested that the chewing ability is closely related to the QOL of the elderly residing in a rural community in Japan.

“…Probable reasons [3,4] include the impact of tooth loss on digestive function because of food not being chewed adequately; people suffering from tooth loss may also alter their diet or eating efficiency and, thereby, fail to provide the body with adequate nutrition. Studies have also pointed out that chewing ability directly impinges on the quality of life [5,6], life expectancy [7], and the mortality rate [8] among the elderly. Reducing the number of missing teeth in people older than 65 years was the main goal of a World Health Organization initiative in 2000 [9].…”

The purposes of this study were to (1) examine the relationship between the number of various types of healthy remaining natural teeth at different sites and self-rated chewing ability and (2) evaluate the relationship between the number of functional tooth units (FTUs), comprising functional natural teeth (FNT) or fixed prostheses, and self-rated chewing ability. A sample of 296 adults (122 men and 174 women), aged 45 years or older (average age, 56.6±9.7), were recruited from seven dental clinics in Kaohsiung City. Dental information on the number and status of remaining teeth was obtained through examination by trained and calibrated dentists. Self-assessment of chewing ability (masticatory score) was evaluated with a self-administered questionnaire. Results showed that increased age is associated with a greater likelihood of difficulty in chewing. To avoid chewing difficulty, at least 24.7 FNT, 13.3 posterior-FNT, 8.1 units of natural tooth-FTUs, or 9.6 units of fixed tooth-FTUs must remain. Age and the number of healthy remaining teeth, including natural teeth and fixed prostheses, are key factors in chewing ability. Given that aging is unavoidable, the preservation of healthy remaining teeth plays a relatively important role in the maintenance of chewing ability among middle-aged and elderly people.

“…Subjective assessments include measurements of the self‐satisfaction of the masticatory function in daily life, as reported by Locker (3). Miura (4) also reported that the life satisfaction of seniors is based mainly on food acceptance. Recently, it was reported that there was a significant correlation between the subjective Food Intake Ability (FIA) and objective bite force (5).…”

This study examined the differences in the masticatory function of patients with temporomandibular disorder (TMD) in Korea. The experimental groups were as follows: 23 patients with painful arthralgia classified as pain group according to the research diagnostic criteria for temporomandibular disorder (RDC/TMC) and 28 patients with pain-free disc displacement and reduction classified as clicking group. The subjects were obtained from those who had visited Yonsei University Dental Hospital from 2007 to 2008. Twenty dental students without TMD symptoms were enroled as the normal control group. The Mixing Ability Index (MAI) was used as the objective index, and the Food Intake Ability (FIA) Index, Visual Analogue Scale (VAS) and oral health impact profile (OHIP) were used as the subjective indices. The MAI, FIA and VAS were significantly lower in the pain group than in the normal and clicking groups (P<0·05). The pain group showed a MAI, FIA and VAS of 16%, 81% and 67%, respectively, compared to that of the normal group. However, there were no significant differences in the MAI, FIA and VAS between the clicking and normal groups. The pain and clicking groups showed a 1·7 and 1·4 times higher OHIP value than the normal group (P<0·05). The MAI and subjective indices, such as the FIA (r=0·40) and VAS (r=0·48), showed a moderate correlation (P<0·01). In conclusion, pain is the main factor for the reduced masticatory function in patients with TMD in Korea, and the joint sound, not the masticatory function, affects the declining OHIP.
