Conclusions Most studies revealed a positive association between mastication and obesity among adults .
Background A substantial number of adults suffer from obesity , that is caused by the risk factor , masticatory dysfunction .
The association between mastication and obesity , however , is inconclusive .

The relationship between oral health status and Body Mass Index among older people: a national survey of older people in Great Britain
Aims To assess the relationship between oral health status and Body Mass Index . Material and methods This paper relates to the free-living sample ( participants who lived in their own home , rather than an institution ) of the National Diet and Nutrition Survey : people aged 65 years and older . Subjects 629 adults . Data collection A probability r and om national sample of adults who had a dental examination , an interview and an anthropometric examination .  Data analysis Fisher 's exact test and multivariate logistic modeling . Findings Being underweight was relatively uncommon in this population . People without teeth were significantly ( P=0.05 ) more likely to be underweight than those with 11 or more teeth ; 12.3 % and 2.9 % . A highly statistically significant ( P=0.001 ) difference was observed in BMI between dentate people with 1 - 10 teeth and with more than 10 teeth ; 24 % and 2.9 % were underweight . Dentate people with less than 21 natural teeth were on average more than 3 times more likely to be obese than those with 21 - 32 teeth ( P=0.036 ) . There was no significant difference in both the proportion of overweight and obese adults between those who were edentulous and dentate with 21 or more teeth . A similar pattern was observed when the number of posterior occluding pairs was compared with BMI categories . Results of multiple logistic regression were adjusted for the confounding effects of age , social class , region of origin and partial denture wearing . Conclusions Older people in Britain with more than 20 teeth are more likely to have a normal Body Mass Index
