Abstract: | The discriminatory ability of radiological criteria in common use in clinical trials was tested on 99 female teenagers selected from a larger sample taking part in a 3–year caries prophylactic clinical trial. Four radiological caries diagnostic criteria were selected as generally representative of those in current use following a comprehensive review of the literature. A significant preventive effect was evident from the radiographic examinations after 3 years. At this time a significant difference between mean DFS increments was recorded when enamel lesions were omitted (P < 0.05). Although preventive treatment effects were evident at all diagnostic levels, the discriminatory abilities differed. The criterion “involvement of amelodentinal junction but not beyond” was most discriminatory. |
