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 .
Oral health and obesity indicators
Background In western Sweden , the aim was to study the associations between oral health variables and total and central adiposity , respectively , and to investigate the influence of socio-economic factors ( SES ) , lifestyle , dental anxiety and co-morbidity . Methods The subjects constituted a r and omised sample from the 1992 data collection in the Prospect i ve Population Study of Women in Gothenburg , Sweden ( n = 999 , 38- > = 78 yrs ) . The study comprised a clinical and radiographic examination , together with a self-administered question naire . Obesity was defined as body mass index ( BMI ) > = 30 kg/m2 , waist-hip ratio ( WHR ) > = 0.80 , and waist circumference > 0.88 m. Associations were estimated using logistic regression including adjustments for possible confounders . Results The mean BMI value was 25.96 kg/m2 , the mean WHR 0.83 , and the mean waist circumference 0.83 m. The number of teeth , the number of restored teeth , xerostomia , dental visiting habits and self-perceived health were associated with both total and central adiposity , independent of age and SES . For instance , there were statistically significant associations between a small number of teeth ( < 20 ) and obesity : BMI ( OR 1.95 ; 95 % CI 1.40 - 2.73 ) , WHR ( 1.67 ; 1.28 - 2.19 ) and waist circumference ( 1.94 ; 1.47 - 2.55 ) , respectively . The number of carious lesions and masticatory function showed no associations with obesity . The obesity measure was of significance , particularly with regard to behaviour , such as irregular dental visits , with a greater risk associated with BMI ( 1.83 ; 1.23 - 2.71 ) and waist circumference ( 1.96 ; 1.39 - 2.75 ) , but not with WHR ( 1.29 ; 0.90 - 1.85 ) . Conclusions Associations were found between oral health and obesity . The choice of obesity measure in oral health studies should be carefully considered
