Transmission of Str Mutans from mother to baby 2. Wrong feeding habits 3. Lack of education 4. Interaction of bacteria, tooth surface, and sugary food. What are the primary ______ of Early Childhood Caries (ECC) according to the text?

<p>risk factors</p> Signup and view all the answers

Transmission of Str Mutans from mother to baby: Infants acquire MS from their mothers only after the eruption of primary teeth. There is not MS in oral cavity before tooh eruption. Children acquire MS during a discrete period between the age of 19 and 33 months, designated as the ‘ first window of infectivity’, and the source of initial infection mostly is through ______.

Prolonged and nocturnal (night time) breastfeeding or bottle feeding is associated with an increased risk of ECC, especially after the age of 12 months. Breast milk has lactose in it. Breastfeeding should be finished in 1520 minutes. Prolonged feeding accumulates milk on teeth the whole night which will cause to start the ______.

The aetiology and prevention of ECC are strongly determined by sociobehavioural, economic, environmental, and societal factors, known as the social determinants of ______.

<p>health</p> Signup and view all the answers

The aetiology is frequently linked with a high-frequent consumption of sugared drinks or food, lack of breastfeeding, and/or poor oral hygiene. Additionally, the disease often manifests in children from poor families or living in poor environmental ______.

If salivary flow is impaired, dental caries can progress very rapidly. Saliva not only physically removes dietary substrates and acids produced by plaque from the mouth, but it has a most important role in buffering the pH in saliva and within plaque. Fast-flowing saliva is alkaline⎯reaching pH values of 7.5-8.0⎯and is vitally important in raising the pH of dental plaque previously lowered by exposure to sugar and carbohydrates. Because teeth consist largely of calcium and phosphate, the concentration of calcium and phosphate in saliva and plaque is thought to be important in determining the progression or regression of ______.
