Chewing Ability (chewing + ability)
Selected AbstractsGeneral Health Status and Changes in Chewing Ability in Older Canadians over Seven YearsJOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 2 2002David Locker PhD; Abstract Objectives: The purpose of this study was to describe the onset of and recovery from chewing problems in an older adult population over a seven-year period and to describe factors associated with these changes. Of particular interest was the relationship between general health and changes in oral functioning - Methods: The data came from a longitudinai study of community-dwelling individuals who were aged 50 years and older when first recruited. Data were collected at baseline (n=907) and at three (n=611) and seven-year (n=425) follow-ups. Oral function was assessed by means of a six-item index of chewing ability. Data were weighted to account for loss to follow-up using weights derived from the seven-year response proportions for dentate and edentulous subjects. Logistic regression analysis using backward stepwise selection was used to identify. predictors of onset and recovery. Results: At baseline, 25 percent of subjects reported a problem chewing. This rose to 26 percent at three years and 34 percent at seven years. The seven-year incidence of chewing dysfunction was 19 percent. Of those with a chewing problem at baseline, 21 percent did not have a problem at seven years. A logistic regression model predicting the seven-year incidence of chewing problems indicated that subjects aged 65 years or older, the edentulous, those rating their oral health as poor, those without dental insurance and those without a regular source of dentai care were more likely to be an incident case. In addition, a variable denoting the number of chronic medical conditions at baseline also entered the model. A logistic regression model predicting recovery indicated that older subjects, the edentulous, those from low-income households, and those with limitations in activities of daily living were less likely to recover over the observation period. Conclusion: The results of this study indicate a marked increase in the prevalence of chewing problems in this older adult population over the seven-year observation period. Poorer general health at baseline increased the probability of the onset of a chewing problem and decreased the probability of recovery.

TAKATA summary, As quality of life (QOL) could be influenced by oral status in the elderly, we examined whether chewing ability or number of teeth affected QOL in 80-year olds. A cross-sectional survey included dental examination, chewing self-assessment, and a QOL questionnaire. A total of 823 people who were 80 years old participated in this study. QOL was assessed in terms of satisfaction with physical condition, meals, daily living and social interactions, and with face-scale scores. After adjustment for gender, spouse and activities of daily living, dissatisfaction with social interactions was 3·9 times more prevalent in individuals able to chew four foods or fewer than in those chewing 15. Dissatisfaction with physical condition, meals and daily living, and poor face-scale scores, were 2·7, 2·4, 3·4, and 2·4 times more prevalent, respectively, in subjects chewing four foods or fewer. The number of teeth showed little effect. In conclusion, self-assessed chewing ability but not number of teeth was associated with QOL in 80-year-old subjects.

Miura 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. [source] Relationship between symptoms of temporomandibular disorders and dental status, general health and psychosomatic factors in two cohorts of 70-year-old subjectsGERODONTOLOGY, Issue 3 2007Tor Österberg Objective:, To study the prevalence of symptoms of temporomandibular disorders (TMD) in two cohorts of 70-year-old subjects examined 8 years apart and analyse the relationship between such symptoms and dental status, general health and various background factors. Materials and methods:, Two cohorts of 70-year-old subjects, born in 1922 (n = 422) and 1930 (n = 491) respectively, were examined with an interval of 8 years. A TMD symptom index (0,5) was established on answers to five questions related to TMD symptoms. Results:, There were no statistically significant differences between the two cohorts for prevalence of TMD symptoms and TMD index, neither for headache, neck ache, bruxism and chewing ability. TMJ sounds was the most prevalent symptom, 14%, whereas other TMD symptoms had low prevalence. The distribution of the TMD symptom index showed that 81% reported no symptoms, 15% one symptom, 3% two symptoms and 1% three to five symptoms. Single TMD symptoms and the TMD index exhibited significant associations (p < 0.001) with bruxism, headache, neck pain and several general health and psychosomatic factors, but with dental status only in women. Logistic regression showed that bruxism, neck pain, mouth dryness and a number of psychosomatic factors were associated with the TMD index. Conclusions:, Besides TMJ sounds (14%), other TMD symptoms were rarely reported by the 70-year-old subjects. The TMD index was significantly associated with bruxism and several general health and psychosomatic complaints but with dental status only in women. [source] Subjective food intake ability in relation to the Mixing Ability Index in Korean adultsJOURNAL OF ORAL REHABILITATION, Issue 4 2010S.H. JEONG Summary, This study examined the association between the subjective food intake ability (FIA) using a questionnaire with 30 types of foods and the objective Mixing Ability Index (MAI) using a two-coloured wax cube. A total of 147 subjects (32 males, 115 females, mean age: 54·9 ± 20·7) were enrolled in this study. The FIA for 30 food types and the key food intake ability (KFIA) for five key food types were obtained using a self-assessed questionnaire to evaluate the subjective chewing ability. The objective chewing ability was evaluated by asking the subjects to chew a wax cube for 10 strokes. The MAI was calculated by image analysis of the chewed wax cube. The Pearson's correlation between the subjective FIA and objective MAI was analysed according to age and number of post-canine teeth lost. The FIA for the 30 foods and five key food types showed a moderate correlation with the MAI (r = 0·51, 0·55, respectively, P < 0·01). The KFIA of the denture wearing group (r = 0·44, P < 0·01) and over 60-year-old group (r = 0·49, P < 0·01) showed a significantly higher correlation with the MAI than the other groups. In conclusion, there was a moderate correlation between the subjective FIA and objective MAI in Korean adults. [source] Gastric emptying rate in subjects with experimentally shortened dental arches: a pilot studyJOURNAL OF ORAL REHABILITATION, Issue 6 2008Y. HATTORI Summary, Although a shortened dental arch has been reported to provide sufficient subjective chewing ability, the loss of molar occlusion significantly reduces trituration ability, and may result in an impaired digestive function including delayed gastric emptying. This study investigated the effect of the experimental loss of molar occlusion on gastric emptying rate. Thirteen healthy dentate males underwent two sessions of gastric emptying rate measurement after ingestion of the same test meal that contained ham, bread and an egg mixed with carbon-labelled octanoic acid. A test food was divided into nine equal portions, and each was consumed in 60 cycles of chewing. In one of the two sessions, the subjects wore an intraoral appliance devised to simulate the occlusal conditions of the shortened dental arches. Two parameters of gastric emptying; namely, the lag phase (Tlag) and gastric half-emptying time (T1/2), were evaluated by means of a 13C-octanoic acid breath test. Following the measurement of gastric emptying in each session, masticatory performance was evaluated by a conventional sieve test. Masticatory performance decreased significantly in case of loss of molar occlusion (78·1 ± 11·1% versus 33·4 ± 18·2%, P <0·001); however, no significant changes were observed in terms of the gastric emptying parameters (Tlag: 99 ± 19 versus 105 ± 34 min; T1/2: 168 ± 32 versus 178 ± 48 min). Within the limitations of this study, it was concluded that reduction in food trituration caused by shortening of the dental arch does not significantly affect gastrointestinal digestive function.

[source] Usage and status of cobalt,chromium removable partial dentures 5,6 years after placementJOURNAL OF ORAL REHABILITATION, Issue 2 2002A. L. P. Yeung The aim of this study was to describe the usage of cobalt,chromium (Co,Cr) removable partial dentures (RPDs) by patients 5,6 years after denture insertion and to find out the factors that affected their denture usage. A random sample of patients provided with Co,Cr RPDs from a dental teaching hospital in Hong Kong was selected. Patients were interviewed using a structured questionnaire concerning their assessment and use of the dentures. Those who had been constantly wearing their original RPDs were examined by one calibrated examiner under optimal clinical conditions. The response rate of the patients who could be contacted was 98%. The results from 189 patient interviews showed that usage of the RPDs declined with time and that half of the dentures had been discarded or replaced 5,6 years after insertion. These discarded RPDs had been in use for an average of 19·5 months. The main reason given by the patients for not using the RPDs was general dissatisfaction with the dentures in various combinations of comfort, fit and chewing ability and, less importantly, with food trapping and appearance. No statistically significant association between denture usage and their respective Kennedy classification was found. The status of the Co,Cr RPDs that had been constantly used for 5,6 years was generally good. The majority of these RPDs demonstrated fair to good cleanliness, stability and retention and had no defect of any sort.

[source] Eating and rumination behaviour in Brahman grade cattle and crossbred water buffalo fed on high roughage dietANIMAL SCIENCE JOURNAL, Issue 5 2010Renato S. A. VEGA ABSTRACT The purpose of this study is to compare feeding and other behavior and nutrient digestibility of tropical grade Brahman (body weight (BW) = 231 kg ± 12.4; n = 3) and crossbred water buffalo (BW = 300 kg ± 13.9; n = 3). This experiment on digestibility and measures of muscles of mastication utilized one-way, and animal behavior two-way, analysis of variance, respectively. Two video camcorders were installed in each pair of buffalo and Brahman for 24 h period programmed on the 107th, 109th and 111th days of the digestion trials. Frequency and duration of feeding, meal intake, rumination, bolus, chews, drinking, defecating, standing and lying were recorded daily. Muscle diameter of Digastricus, Masseter and Pterygoid and different regions of the tongue were sampled and measured under light microscope using a standard micrometer. Buffalo obtained significantly higher intake of dry matter, roughage, crude protein, total digestible nutrient and metabolized energy than Brahman. This was supported by longer meal duration (P , 0.05), and shorter meal breaks (P , 0.05) of buffalo than Brahman. The diameter of the muscles for mastication was bigger (P , 0.05) in buffalo than in Brahman, which is indicative of stronger chewing ability. Briefly, lesser and slower chewing action; higher intake of roughage and crude protein; and longer resting behavior of crossbred water buffalo than Brahman are all indicative of better digestive and metabolic performance of the buffalo under high roughage feeding conditions.
