One-Year Clinical Evaluation of the Retention of Glassionomer Sealant on Newly Erupted First Permanent Molars in Children

The effectiveness of dental sealants mainly depends on their retention, or that is what most authors claim. There is a great number of clinicians who believe that partial loss of a sealant leads to the same risk of caries development, identical to that of not silanized occlusal surfaces. The aim of this clinical trial is to evaluate the retention and caries-preventive effect of glass ionomer sealant on newly erupted first permanent molars.
