Microstructures were fabricated on optical imaging fibers with a photopolymerization technique. Monodisperse polymeric microarrays were produced containing spots of 2.5 micrometers in diameter spaced 4.5 micrometers apart. Polymer microarrays were also deposited on other substrates by using imaging fibers for light delivery. The technique allows micrometer-scale photopatterning with masks larger than the desired dimensions.

OBJECTIVES: This study was designed to examine the effect of the application of radiant heat on the fluoride release from the surface of a glass polyalkenoate cement. METHODS: The radiant heat was applied at different intensities and for different time intervals using a high-intensity fibreoptic quartz halogen light source. A standard technique was used to measure the amount of fluoride released from one surface of a cement specimen into deionized water. Fluoride release was measured for a time period of over 2 years. RESULTS: Results showed that fluoride was still being released 2 years after placement. The application of radiant heat did not have a statistically significant effect on the release of fluoride from the surface of this material. CONCLUSIONS: There appeared to be a trend suggesting that the greater the amount of heat applied, the less fluoride was released from the surface of the cement. A considerable inter- and intrabatch variation was noted in the amount of fluoride released from the cement.
