An alginate impression is used in dentistry to make an exact replica of the patientâs teeth, gingiva, and surrounding tissues in the mouth. The alginate dental impression forms an imprint (i.e. a ânegativeâ mould) of those teeth and gums, which can then be used to make a cast or âpositiveâ model of the patientâs dentition. Alginate impression material begins as a powder.
For example, the World Health Organization recommends keeping added sugar intake to 10% of total calories. For the average 2000 calorie-diet that's a maximum of 50 grams. The American Heart Association recommends 6 teaspoons of sugar for women and 9 for men (1 teaspoon of sugar has about 4g of sugar).
For most adults, this works out to be no more than 50g or 12 teaspoons of sugar per day (1 teaspoon holds about 4g of sugar), from all sources of food and drink. However, Australians currently consume about 30 teaspoons of sugar a day on average â more than double the recommended amount!
