27. Desenvolvimento de biomaterial composto por hidroxiapatita e clorexidina para aplicação na cavidade oral
Resumo A hidroxiapatita (HAp) está presente no organismo humano nos tecidos ósseos e dentários, em que do total da massa de cada tecido 30 a 70% correspondem a HAp, podendo ser aplicada como revestimentos de próteses ou até substituição de pequenas partes ósseas. Assim, o objetivo foi sintetizar HAp por precipitação, incorporar clorexidina (CHX) e

32. Doxycycline-containing glass ionomer cement for arresting residual caries: an in vitro study and a pilot trial
Abstract In a previous study, we demonstrated that the incorporation of doxycycline hyclate (DOX) into resin-modified glass ionomer cement (RMGIC) inhibited important cariogenic microorganisms, without modifying its biological and mechanical characteristics. In this study, we keep focused on the effect of that experimental material as a potential therapy for
