RESUMEN
Traditional atraumatic restorative treatment(ART) induces more successive diseases in the treatment of deciduous caries. Ignoring the disinfection and caries-affected dentin's remineralisation are the main reasons of such problem. Nowadays, Ozone-Remineralisation therapy has become one of the steps before restorative treatment. However, there is no quantitative standard to evaluate this therapy. Some researches had shown that the laser-fluorescent device (DIAGNOdent, Dd) has the advantages in monitoring caries treatment. We use DIAG-NOdent to monitor the effect of OZone-Remineralisation therapy before filling the restoration in the caves in this study, however, the results is delievered that DIAGNOdent has little advatages in monitoring the effect of this new therapy, because the data of DIAGNOdent had a large fluctuation.
