Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Children have undergone in three experimental sessions with a one-week washout period. The salivary pH of resting saliva will be measured before (control), then the dietician gave the participants 355 mL of one of the following types of milk: 1. high-protein milk, 2. full-fat milk, and 3. sweetened milk. The salivary pH will be measured after 5, 10, 15, 30, and 60 minutes.
High protein milk is made up of 100% skimmed cow's milk, it contains 8.3g of protein per 100 ml. Full-fat milk contains 3.5% of fat. The participants will be asked to consume the milk within 10 minutes. The investigator ask the participant to return the empty milk containers.

Summary
Brief summary
Nutrition is essential for the growth and development. A healthy diet must meet the body's energy, caloric requirements and provide essential nutrients to meet physiological needs, especially in children. Milk is the first food for humans and the only food found in nature that is richer in nutrients which the body needs, as it provides many of nutrients that are necessary for human body growth in proportionate amounts.
Drinking sweetened and flavored processed milk is part of the children's diet It is known that milk is a non-cariogenic food , this study aimed to monitor saliva pH changes after consuming three different types of canned sweetened milk in children with different incidence of dental caries at the age of 3 -5 years.
