Necesidad o no del uso de colorantes durante la remoción de la dentina cariada: soporte microbiológico
Abstract
The complete dentinal caires removal is a complex process, because the difficulty in define an objetive judgment in order to distinguish between infected and afected dentin. One way to reduce that subjectivity is using a caries detector dye. Nevertheless, there is a controversy about indications, advantages and disadvantages of this technique. This study compared the efectiveness of a conventional tactile and optical criteria and the use of a caries detector dye (1% acid red in propylene glycol) in dentinal caries removal. The microbiological sampling of dye stained and dye unstained dentin were cuantily and classify in 34 patients who presented moderate tooth decay. The results of this investigation showed that 97% of the cavities after dentinal caries removal, showed dye stain more fecuently in the pulpal wall and the enamel - dentin junction. It is known that dyes stain carious dentin, sound dreumpulpal dentine and enamel-dentin junction, and its use could result in unnecesary sound dentin removal and several pulpal exposure. The Lactobacilli adn Mutans strpptococci comprised only 12.79% of the cultivable flora and 61.81 % were not identify and their role in the porgression in dental caires is unknown. It was not found correlation between the caries advanced front, decoloration and bacterial front.
