Objectives: The purpose of this in-vitro study was to assess the validity and reproducibility of the diagnosis and treatment planned for occlusal surfaces prior to and following the placement of a clear sealant by a sample of general dental practitioners (GDPs). Methods: 160 permanent posterior teeth were examined by 25 GDPs. The GDPs were not given any criteria and were therefore free to diagnose and plan care, as they felt appropriate. Each GDP conducted four examinations, two prior to and two after sealing. The teeth were serially sectioned to provide the validating criterion. Results: After sealant placement, there was a statistically significant increase in specificity and decrease in sensitivity of both diagnostic and treatment decisions. The reproducibility expressed by the κ-statistic was of the order of 0.5 prior to and after sealing with regard to diagnostic decisions. There was a general tendency to diagnose less disease after placement of a sealant ( P<0.001). There was also significantly less care (preventive or restorative) planned after sealant placement ( P<0.001). Conclusions: The placement of a sealant resulted in the diagnosis of less disease and less restorative treatment. This may be appropriate as evidence exists to support the use of sealants as caries therapeutic agents.
