Obesity and obesity related diseases, sugar consumption and bad oral health: a fatal epidemic mixture. The pediatric and odontologist point of view

Obesity and dental caries are increasingly widespread pathologies. The former is growing so rapidly that the WHO classified its trend as an “epidemic”. Both are triggered by a number of well known common etiologic factors sharing also the high added sugar amount since childhood. Because of its fermentation and pH lowering, dietary sugar allows the cariogenic bacteria to damage the tooth enamel provoking the carious lesions. WHO guidelines recommend reducing sugar intake to 10% of the total daily energy need, and highlight that there is evidence which suggests cuttingthis value down to 5% at least. The American guidelines addressing paediatric age put the limit to 25gr a day with a total ban on sugar in those aged 2 or less.
