System for the pH-dependent Release of a Dye in Model Dental Restorations:

摘要: We are developing a system for detecting recurrent caries under dental restorations. The controlled release of dyes conditions likely demineralization will alert the dentist to potential secondary caries. Production acidic species is characteristic activity; hence, uses pH-sensitive polymers markers when pH at cavity wall restored tooth below 6.5. objectives this investigation were test hypotheses that (1) proposed can be designed detectable marker continuously least six months in simulated carious environment, and (2) transient changes oral caused by dietary intake not induce premature from polymer placed beneath Two types dye-loaded microspheres based on styrene, vinylpyridine, divinylbenzene prepared floor model preparations made an acrylic rod. Each was res...
