ABSTRACT
Background: To evaluate in vitro the effect of three pediatric mouth rinses on the color stability of three different composite resins. Material and Methods: One hundred thirty-two disc-shaped samples (n = 132) were prepared, with 44 for each type of composite resin (n = 44), and the initial color values were measured with a spectrophotometer. Eleven (n= 11) samples were placed in each immersion substance, and 3 types of pediatric mouthwashes were used with distilled water as a control. The samples were placed in an incubator at 37°C for one hour (equivalent to 1 month of mouthwash use). and color measurement was performed. Color change values (ΔE*) were obtained and the results were statistically analyzed. Kruskal Wallis and Mann-Whitney U tests were used to compare the values between groups (P<0.05). Results: All composite resin samples showed color changes after immersion in the different solutions studied. The ΔE* showed that pediatric mouth rinses produced significant changes in color of the composites tested. The group of nanohybrid resins presented lower levels of change in color stability (ΔE * = 4.63), followed by bulk resins (ΔE * = 5.70) and, finally, nanoparticle resins presented greater effects in color stability. (ΔE *= 5.84). Conclusions: All the composite resin restorative materials used showed differences in color after immersion in the 3 mouthwashes and the distilled water analyzed, these changes should be taken into by dentists working with pediatric patients - o - by pediatric dentists. Key words:Mouthwashes, color stability composite resins, bulk resins, surface roughness.
ABSTRACT
El objetivo de este artículo es revisar información enfocada en mitos sobre la gestación y la salud oral. Las gestantes son consideradas un grupo prioritario de atención en salud, pero una de las barreras más importantes para que esta atención sea realizada son las creencias populares que trascienden de generación en generación. Entre estas, podemos encontrar algunos mitos como el que las mujeres embarazadas desarrollan un mayor número de lesiones cariosas, debido a que el ser en formación requiere mayor requerimiento de calcio. De igual forma, se acepta como un proceso normal durante la gestación que por cada hijo se pierde un diente. Así mismo, existe también la creencia que la atención odontológica causa daño al feto por el uso de anestésicos locales o medicamentos. Otro de los mitos más temidos es la toma de imágenes radiográficas durante la gestación y si el uso de amalgama en las restauraciones dentales es toxicas para el bebé. (AU)
The objective of this article was to review information focused on myths about pregnancy and oral health. Pregnant women are considered a priority group in health care, but one of the most important barriers to this care is the popular beliefs passed on from generation to generation such as the myth that pregnant women develop more carious lesions because of their condition and calcium requirements. In addition, it is often said that for every pregnancy a woman has a tooth is lost. There is also the belief that dental care causes harm to the fetus by the use of local anesthetics, medications, radiographic images and that the use of amalgam in dental restorations is toxic to the fetus.
