Orodental trauma
In contrast to dental caries and periodontal disease, reliable data on the frequency and severity of orodental trauma are still lacking in most countries, particularly in developing countries (22). Some countries in Latin America report dental trauma in about 15% of schoolchildren, whereas prevalences of 5–12% have been found in children aged 6–12 years in the Middle East. Furthermore, studies from certain industrialized countries have revealed that the prevalence of dental traumatic injuries is on the increase, ranging from 16% to 40% among 6-year-old children and from 4% to 33% among 12–14-year-old children (24). A significant proportion of dental trauma relates to sports, unsafe playgrounds or schools, road accidents or violence.
