Throughout the precedent few decades’ changes have been observed not just in the commonness of dental caries, however also in the distribution and pattern of the disease in the population. Most particularly, the comparative distribution of dental caries on different tooth surfaces has changed, and the rate of scratch progression through teeth has slowed. These changes have significant implications for diagnosing and treating initial lesions, predicting caries risk, and conducting effective disease prevention programs for individuals or populations. Scientific research continues to make improvement in the classification of best practices for diagnosing, treating, and preventing dental caries. Traditional approaches for treating carious lesions in a surgical manner are being replaced by newer strategies that emphasize disease prevention and conservation of tooth structure.
Even though considerable progress has been made in falling and controlling dental caries, the disease at a halt remains a trouble for a lot of children and adults in the United States. Approximately 20 percent of children between the ages of two and four years have had dental caries, and by age 17 nearly four of five youngsters have had at least one carious lesion (cavity) or restoration (filling). More than two-thirds of adult’s ages 35 to 44 years have lost at least one permanent tooth and about one of every two persons 75 years or older has had root caries affecting at least one tooth. Dental caries is an infectious, communicable disease resulting in destruction of tooth structure by acid-forming bacteria found in dental plaque, an intraoral biofilm. The disease can result in irreversible loss of tooth minerals and eventually extraction of the tooth, if left unchecked. The availability of fluoride in the mouth, however, can inhibit demineralization, or mineral loss, in early carious lesions and promote remineralization of tooth structure leading to rebuilt and stronger outer layers of the tooth (i.e., enamel on the crown of the tooth and cementum on the root)..........
