Abstract

"MéTODOS DE DIMINUIR A PERMEABILIDADE DA DENTINA, DE DESSENSIBILIZAR DENTINA E CIMENTO HIPERSENSìVEIS, DE DIAGNOSTICAR DOR DENTINAL REVERSìVEL E IRREVERSìVEL EM UM PACIENTE E DE FORMAR UMA SOLUçãO DE DI-HIDRATO DE SAL DE POTáSSIO DO áCIDO OXáLICO, E, COMPOSIçãO LìQUIDA E ESTáVEL DE DI-HIDRATO DE SAL DE POTáSSIO DO áCIDO OXáLICO". Um processo de utilização de uma solução de sal de potássio do ácido oxálico, di-hidrato 99%, para reagir com cálcio no fluido dentinal, formando um precipitado branco insolúvel de oxalato de cálcio que oclui os túbulos dentinais, causando menor sensibilidade, permeabilidade e penetração a ácido da dentina. Uma composição líquida de sal de potássio do ácido oxálico, di-hidrato 99%, contendo de aproximadamente 1,5% a aproximadamente 10%, em peso, de sal de potássio do ácido oxálico, dihidrato 99%, tendo um tamanho de partícula de aproximadamente 1 a aproximadamente 10 micra quando visualizado por um microscópio de 100x de aumento. A composição liquida tem um pH de aproximadamente 2,0 a 4,0. Métodos de preparação da composição líquida são descritos."METHODS OF REDUCING DENTIN PERMEABILITY, DENSENTIALIZING HYPERSENSIBLE DENTIN AND CEMENT, REVERSIBLE AND IRREVERSIBLE DENTAL PAIN DIAGNOSIS, FORMING A POTHYDRAX LILACS AND DIACHYDAL SALT SOLUTION OXYLIC ACID POTASSIUM DI-HYDRATE ". A process of using an oxalic acid potassium salt solution, dihydrate 99%, to react with calcium in the dentinal fluid, forming an insoluble white calcium oxalate precipitate that occludes the dentinal tubules, causing less sensitivity, permeability and acid penetration of dentin. A liquid composition of oxalic acid potassium salt, dihydrate 99%, containing from approximately 1.5% to approximately 10% by weight of oxalic acid potassium salt, dihydrate 99%, having a particle size of approximately 1 to about 10 microns when viewed by a 100x magnification microscope. The liquid composition has a pH of approximately 2.0 to 4.0. Methods of preparing the liquid composition are described.
