To date there is no standard protocol on evaluation of the masticatory performance in complete denture wearer even though many methods had been described in the literature for measurement of the masticatory performance of the complete denture wearers. The masticatory performances were measured either subjectively or objectively, but no positive correlation was found between subjective and objective measurement. Therefore, there is a need to standardize the objective measurement, as subjective measurements rely on patients' perceptions, which is not reliable. Intra individual and inter individual variations that exist support the need to standardize the method of measurement.Key words: masticatory performance, complete denture. INTRODUCTIONThe efficiency and success of complete dentures are difficult to measure objectively. It is important to be able to do so because patients sometimes complain with no clinical evidence (1,2). Most patients expect dentures to be comparable, both functionally and esthetically, to a natural dentition (3). To predict individual patients' ability to chew test foods, dentists cannot rely on subjective responses to questionnaires on chewing difficulties or on the complete denture. However, a series of chewing tests can determine the individual masticatory performance. An objective test of masticatory performance could provide useful information of edentulous subjects wearing complete denture; later this information could support advice and decisions made by the dentists to patients on the treatment and the treatment outcome (4). OBJECTIVESTooth loss is significant in elderly people, partly due to poor oral health. Fiske and Lewis (1995) suggested that oral health is important in the elderly in terms of their ability to eat healthy nutritious food (5), as elderly with a reduced number of teeth had a poor quality diet (6). It is important to have good oral health and chewing ability, either by means of the remaining teeth or with dentures (7).The selection of food by the elderly was affected by the number of teeth, the number of occluding pairs and the presence of complete dentures (8,9). The wearing of complete dentures also resulted in changes in masticatory function compared with dentate subjects (10-12). Therefore, a measurement of the performance and the efficiency of masticatory function is important as restoring the masticatory function is one of the purposes of complete denture construction (13).The objective of this paper is to give a brief insight into the masticatory performance and efficiency of complete denture wearers and various methods used to establish the masticatory performance of the edentulous patients. MASTICATORY FUNCTION Definition"The ability of a patient to masticate is measured in two ways, i.e (1) Masticatory efficiency and (2) Masticatory performance"-Bates, Stafford and Harrison (10). From the Glossary of Prosthodontics (14), masticatory efficiency is defined as the effort required achieving a standard degree of comminution while masticatory performance i...

The purpose of this study was to investigate differences in oral condition and health status between persons with 20 or more teeth at the age of 80 (8020 elderly) and persons of the same age with less than 20 teeth (non-8020 elderly). This study was conducted by a team belonging to the Aichi Dental Association. Number of remaining teeth, Community Periodontal Index of Treatment Needs (CPITN), salivary blood test, masticatory ability, bone mineral density (BMD), grip strength, balance test (length of time one can stand on one leg with eyes open), height, weight and body mass index (BMI) were all examined. The percentages of CPITN code 0, 1 and 2 were 68% in the 8020 male elderly and 72% in the 8020 female elderly. The positive percentage in the salivary blood test in the 8020 elderly was lower than that in the non-8020 elderly. Masticatory ability was 1.55 g in the 8020 male elderly, and 1.53 g in the 8020 female elderly. Relative masticatory ability in the 8020 female elderly was 20% higher than that in the non-8020 female elderly. BMD in the 8020 female elderly was significantly higher than that in the non-8020 female elderly. Grip strength in the 8020 elderly was also significantly higher than that in the non-8020 elderly. The duration of balance test in the 8020 male elderly was 2.2 times longer than that in the non-8020 male elderly. The 8020 elderly showed good oral condition and health status was found to be better in the 8020 elderly than in the non-8020 elderly.

Decrease in swallowing ability with age may lead to undernutrition, dehydration, and occasionally aspiration pneumonia (Finestone et al 1995;Reza et al 2006).…”

In Japan, one of the duties of the long-term care insurance system is the prevention of oral function degradation. Although various exercise programs for oral function have been developed and practiced in Japan, to date, no study has reported their effects. In the present study, we examined the effects of an exercise program on oral functions in healthy elderly people. Healthy elderly people participated in the study and were randomly divided into intervention and control groups (39 subjects/group). The exercise program consisted of four exercises: exercise for expression muscles, tongue, salivary glands, and swallowing. Before and after a six-month intervention period, we evaluated changes in oral functions, namely bite force, swallowing ability, and salivary flow rate. Fifty-four subjects completed the study protocol: 26 and 28 subjects from intervention and control groups, respectively. A significant improvement in all oral functions, including bite force, swallowing ability, as well as unstimulated and stimulated salivary flow rate, was observed in the intervention group after six months, whereas no improvement was observed in the control group. Further, among the intervention group, a significant improvement in oral functions was observed in 17 subjects with 20 or more remaining teeth, whereas no improvement was observed in the other nine with less than 20 teeth. Our results suggest that oral functions significantly improve after conducting a six-month exercise program for oral function. Further, this improvement appears to be influenced by the number of remaining teeth.exercise program for oral function; healthy elderly people; long term care insurance; stretching exercise; number of remaining teeth.Tohoku

Masticatory performance in 80‐year‐old individuals

Abstract: Most of the 80-year-old individuals recovered their masticatory ability with the assistance of prostheses. Several individuals with 20 or more remaining teeth or without removable dentures present in both jaws had a high score for bite forces and masticatory abilities.
