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 .
This systematic review aims to provide literature regarding the association between mastication and factors affecting masticatory function , and obesity in adults .
Association between number of teeth, edentulism and use of dentures with percentage body fat in south Brazilian community-dwelling older people.
OBJECTIVE To evaluate if poor oral status was associated with percentage body fat in a representative sample of south Brazilian community-dwelling elderly . BACKGROUND Evidence suggests that elders with extensive tooth loss and edentulism present with compromised chewing function , which results in dietary changes . However , few studies have assessed whether poor oral status is associated with percentage body fat in community-dwelling elderly . MATERIAL S AND METHODS A r and om sample of 471 south Brazilians = > 60 years of age was evaluated . Measurements included a question naire to assess socio-demographic , behavioural , general , and oral health data . Percentage body fat was measured with a Tanita TBF 612 digital scale , which measures foot-to-foot bioelectrical impedance ; and  oral status assessment  , by means of oral examinations assessing the number of teeth and use of dental prostheses . Correlates of risk of inadequate percentage body fat were assessed by means of multinomial logistic regression . RESULTS Edentulous participants were more likely to be underfat [ OR : 3.11 ( 1.27 - 7.61 ) ] or overfat/obese [ OR : 1.82 ( 1.05 - 3.16 ) ] . CONCLUSION The present study shows that edentulous older people had higher odds for inadequate percentage body fat . The maintenance of teeth had a crucial role in increasing the chance of having an adequate body fat percentage in the study population
