Abstract
Concomitant to the general caries decline in children and adolescents, caries is mainly concentrated on occlusal surfaces of permanent molars. While occlusal cavities have been shifted to non-cavitated lesions, school-based visual tactile screenings on a cavity level based on the WHO standard (1997) are of limited value as evidence. To avoid cavities or extended restorations current dentistry targets at early prevention or minimal intervention. School-based visual screenings of non-cavitated lesions may support the preventive care strategies of dental practioners. A comparative diagnostic study in 8- to 12-year-olds in the Westfalian Ennepe-Ruhr district showed that occlusal surfaces scored as primarily sound under the WHO standard in fact revealed a high need for preventive (43%) and operative (30%) treatment after using additional visual and laser optical diagnostic measurements. Because of the limited information of the laser optical findings, laser fluorescence diagnostics should not be included in school-based dental screenings. Compromises are needed to introduce visual diagnostic examinations in school-based dental screenings.
