Bioactive capabilities explored in polyurethane microcapsules and the inclusion into dental sealants and cement pastes
Objectives. Caries at the interface of dental materials and mineralized tooth structure continues to be a significant issue in oral healthcare. The objectives of this study were to demonstrate the effect that microencapsulated water has on charging an orthodontic cement and pit and fissure sealant …

Evaluation of resin-based fissure sealants placed under field conditions
BACKGROUND: The application of dental sealants is a recommended procedure to prevent and control dental caries. However, despite strong evidence for the safety and effectiveness of dental sealants, their use still remains low, especially among children from lower socioeconomic communities. The …

Biodegradable Polymeric Ion Releasing Fillers
Dental sealants are a highly effective tool used by dentists to prevent occlusal caries in children by sealing pits and fissures of molars. However, polymerization shrinkage can lead to marginal leakage and secondary caries over time. Biodegradeable polymeric ion-releasing fillers (PIRFs) …

Performance of several diagnostic systems on detection of occlusal primary caries in permanent teeth
… sealant, would be of utmost importance to the dental community. OBJECTIVES: The aim of this two-part in-vitro study is to evaluate the performance of multiple detection methods: The International Caries Detection and Assessment System (ICDAS); two quantitative light-induced fluorescence systems …

Biodegradable Polymeric Ion Releasing Fillers Effect on Pit and Fissure Sealant Properties
… following the procedures outlined in ISO4049 for dental materials. Results: At a shear rate of 1 rpm, the colloids containing PIRFs shear thickened as a function of time, exhibiting rheopectic behavior. At the shear rates of 10 or 25rpm, the colloids shear thinned as a function of time, exhibiting …
