[Fissure sealants as primary preventive measures. Four-year evaluation in Stara Pazova].

Worldwide studies have shown that fissure caries prophylaxis is very difficult using conventional preventive methods. The scientific council of the prophylaxis programme for the protection of mouth and teeth in Vojvodina has begun sealing fissures in Stara Pazova and Novi Sad. The molars of all 6-year-old children were sealed completely. A 77.8% reduction in fissure caries was found at the end of the four-year study. Losses of sealing material came to 16% after four years. Cost-effectiveness analysis: The sealings are three times cheaper than an amalgam filling. Application time: 8-9 minutes.
