Periodontal disease in children.. although periodontal disease is more prevalent in adults, it's important for parents to realise that the disease affects all age groups. about 10 per cent of american children suffer from a virulent form of gum disease known as juvenile periodontitis. this rapidly advancing form of gum disease usually strikes the permanent teeth of otherwise healthy children. the disease often lacks symptoms, and the gums appear normal often, routine dental radiographs reveal bone loss around the teeth, and the disease is then diagnosed. some research indicates that a plaque-induced gum infection is responsible for the disease; others blame hormonal changes taking place during adolescence that may affect the body's immune system, recent research suggests the disease may be hereditary and transmitted through the mother's genes. when diagnosed early, juvenile periodontitis can be treated. if neglected, it can spread beyond the initially affected teeth to the remaining teeth and result in loss of permanent teeth remember, check your teeth often for signs of guni disease. practice good oral hygrene at home, and see your dentist regularly for professional cleansing and treatment. early detection and treatment of periodontal disease can save time and spare painful, costly complications. задайте 5 вопросов к тексту: общий, альтернативный, спец, разделительный и к подлежащему
