Fluoride Concentration in Inter-proximal Fluid From Dental Sealants

NCT01588210 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 2776

No results posted yet for this study

Summary

The hypothesis of this study is that the concentration of fluoride in oral interproximal fluids would increase more after using high-viscosity GIC as pit and fissure sealant, compared to Resin-Based sealants containing fluoride and RB sealants without fluoride content. To validate this hypothesis a randomized clinical trial was designed and performed in schoolchildren in order to evaluate fluoride release in inter-proximal fluid in vivo after the placement of three types of sealants: high-viscosity GIC, Resin-Based sealants containing fluoride and RB sealants without fluoride content.

Sealant application

A high-viscosity glass-ionomer cement (KETAC™ MOLAR APLICAP 3M Espe, Germany) will be used. All sealants was applied following these steps: tooth isolation using cotton rolls or rubber dam; tooth cleaning using a rotary brush mounted on a low-speed contrangle with a prophylaxis pasta without fluoride; enamel etching using 37% phosphoric acid (H3PO4) for 30 seconds; rinse thoroughly with water and dry; placement a thin layer of sealant material and cure according to manufacturer's instructions and finally occlusion adjustment, if necessary.

OTHER

sealant application

A white photopolymerizable Resin-Based sealant containing fluoride (Helioseal F®, Ivoclar Vivadent AG, Fürstentum Liechtenstein) will be used. All sealants was applied following these steps: tooth isolation using cotton rolls or rubber dam (it was mandatory for both the RB sealants); tooth cleaning using a rotary brush mounted on a low-speed contrangle with a prophylaxis pasta without fluoride; enamel etching using 37% phosphoric acid (H3PO4) for 30 seconds; rinse thoroughly with water and dry; placement a thin layer of sealant material and cure according to manufacturer's instructions and finally occlusion adjustment, if necessary.
