Early childhood caries

Early childhood caries (ECC), formerly known as nursing bottle caries, baby bottle tooth decay, night bottle mouth and night bottle caries, is a disease that affects teeth in children aged between birth and 71 months. ECC is characterized by the presence of 1 or more decayed (noncavitated or cavitated lesions), missing (due to caries), or filled tooth surfaces in any primary tooth. ECC has been shown to be a very common, transmissible bacterial infection, usually passed from the primary caregiver to the child. The main bacteria responsible for dental caries are Streptococcus mutans (S. Mutans) and Lactobacillus. There is also evidence that supports that those who are in lower socioeconomic populations are at greater risk of developing ECC.

The main bacteria responsible for dental caries are Streptococcus mutans (S. Mutans) and Lactobacillus. There is also evidence that supports that those who are in lower socioeconomic populations are at greater risk of developing ECC. Early childhood caries (ECC) is a multi-factorial disease, referring to various risk factors that inter-relate to increase risk of developing the disease. These risk factors include but not limited to, cariogenic bacteria, diet practices and socioeconomic factors. Normally after 6 months, deciduous teeth begin to erupt means, they are susceptible to tooth decay or dental caries. In some unfortunate cases, infants and young children have experienced severe tooth decay called ECC. This can result in the child experiencing severe pain, extensive dental restorations or extractions. The good news is that ECC is preventable, however, still remains a large burden particularly towards health care expenditure. The primary cariogenic bacteria involved in ECC are S. Mutans and Lactobacillus. The oral flora in an infant oral cavity is not colonised with normal oral flora until the eruption of the primary dentition at approximately 6 to 30 months of age. The colonisation of S. Mutans from mother to infant is well documented. Over time this combination of food debris and bacteria form a biofilm on the tooth surface called plaque. In plaque, the cariogenic microorganisms are those that produce lactic acid as a by-product from fermentable carbohydrates. Examples of these fermentable carbohydrates include such as fructose, sucrose and glucose. Cariogenic bacteria thrive on these sugars and help them to weaken the adjacent tooth surface. A poor oral care routine and a diet that is high in fermentable carbohydrates favour acidic attack in the oral cavity. This prolonged acidic exposure allows the net loss of minerals from the tooth. This diminishes the strength of the tooth and is called demineralisation. For the outer layer of the tooth (enamel) to reach cavitation, there is a breakdown of the enamel matrix that allows the influx of the cariogenic bacteria. As cavitation progresses into dentine, the dental caries is classified severe, this causes ECC. Diet plays a key role in the process of dental caries. The type of foods along with the frequency at which they are consumed can determine the risk it puts for also developing carious lesions. With new products being put on supermarket shelves with irresistible prices, this can largely influence what people buy. It is common for infants and young children to frequently consume fermentable carbohydrates, in the form of liquids. The consumption of liquids containing fermentable carbohydrate, include drinks such as: juice, breast milk, formula, soda. These consumables all have the potential to increase the risk of dental caries due to prolonged contact between sugars in the liquid and cariogenic bacteria on the tooth surface. Recent research has shown that breastfeeding does not increase caries risk up to 12 months of age. Poor feeding practices without appropriate preventive measures can lead to a distinctive pattern of caries in susceptible infants and toddlers commonly known as baby bottle tooth decay or ECC. Frequent and long duration bottle feeding, especially at night, is associated with ECC. This finding can be attributed to the fact that there is less salivary flow at night and hence less capacity for buffering and remineralisation. Each time a child drinks these liquids, acids attack for 20 minutes or longer. A parent's education and health awareness has a major influence on the caries experience of their child - feeding practices, dietary habits and food choices. Dental caries still today, remains the most prevalent disease worldwide. This means the disease is highly preventable, yet it is still burdening millions of children and into adulthood with pain and potentially lower quality of life. There are several studies by Locker and Mota-Veloso reporting that there is a two-way relationship that exists between dental caries and levels of education, household income that effect quality of life and social positioning. Locker suggested that the relationship between oral disease and health-related quality of life outcomes can be mediated by personal and environmental variables. Previous studies have also mentioned that the rate of ECC has decreased, however, these results can tend to dis-include communities where equity still exists. More health promotion initiatives and policy-making that collaborate directly with the community to increase meeting their needs, should be implemented.
