Effects of Solutions Used to Treat Dental Fluorosis on Tooth Permeability.
ARMY INST OF DENTAL RESEARCH WASHINGTON D C
Pagination or Media Count:
Four solutions h2O2, HCL, McInnes solution, and saline were tested for their ability to penetrate through intact enamel and dentin into the pulp chamber of groups of 10 extracted non-carious teeth. None of the solutions tested appeared to penetrate the enamel and dentin into the pulp chambers as determined by the penetration of tracer amounts of the radioisotope p32 into saline placed in the pulpal chambers. Visual observations showed that both HCL and McInnes solution etched the enamel sufrace, but did not increase the permeability of the enamel and dentin as determined by soaking the teeth in I125 labeled saline.
