Evaluation of preventive treatment by risk of caries among 13-year-olds.

Implementation of caries preventive treatment in relation to the risk of caries was studied among 13-year-olds (n = 132) in two groups treated in the same public dental clinics in Helsinki: caries patients (n = 100) had the greatest numbers of decayed teeth (DT+dt), 5.5 on average, whereas cavity-free patients (n = 32) had intact teeth. Data taken from patients' personal oral health records served for evaluation of individual need for caries prevention, risk of caries, and preventive treatment given to each patient. Patients with any caries lesions or erupting teeth or poor oral hygiene were considered to be at risk of caries and in need of preventive treatment. The more caries lesions a patient had, the more prevention was expected to have been given. Preventive treatment of caries was weakly or only moderately in accordance with patients' individual needs and risk of developing caries, although patients with more caries lesions tended to have been given more preventive treatment than did those with none or only a few lesions. The majority of preventive measures given were applications of fluoride varnish, whereas motivation of and instruction in oral health care habits remained weak. However, patients whom their dentists had judged to be at high risk of caries received more intensified preventive treatment than did other caries patients. As a conclusion, intensification of caries prevention among high-risk patients is still needed. Dentists should always consider each patient's risk of developing caries to improve quality of preventive treatment.
