RESUMEN

Objectives@#This study was conducted to investigate the correlation between the individual characteristics of the children and the teeth that had performed pulpectomy for children who visited Wonkwang University Dental Hospital for 5 years and had pulpectomy performed. @*Methods@#Age, sex, number of teeth that had performed pulpectomy and restorative treatment at the time of diagnosis were investigated, and the correlation was statistically analyzed. @*Results@#The number of teeth had performed pulpectomy and number of teeth had performed restorative treatment were statistically significant (P<0.001). There was a statistically significant correlation between the age and sex of the children who had performed pulpectomy and the number of teeth had performed pulpectomy (P<0.05). @*Conclusions@#In order to improve children’s oral health, it is considered that there is a need for a new national policy to move up children’s first visit to dental clinic and to allow them to visit continuously.

RESUMEN

This study was conducted to investigate the fluoride release of fluoride-containing restorative materials in fluoride recharging according to the concentration of fluoride toothpaste used in Korea.Samples of glass ionomer cement, resin-modified glass ionomer cement, alkasite restorative material, and composite resin were prepared and fluoride release was measured on days 1, 3, 7, 14, 21, 28. Thereafter, fluoride-free, 500 ppm, and 1450 ppm fluoride toothpaste was applied to each restorative materials, and the fluoride release was measured on days 1, 3, 7.Glass ionomer cement showed the highest cumulative fluoride release until the 7th day of measurement, and from the 14th day onwards, the resin-modified glass ionomer cement showed the highest cumulative fluoride release, but there was no significant difference.When restorative material groups were recharged with 500 ppm of fluoride toothpaste, the fluoride release was significantly higher only for the alkasite restorative material compared to the fluoride-free toothpaste group (p < 0.017). When restorative material groups were recharged with 1450 ppm of fluoride toothpaste, the fluoride release was significantly higher in all restorative groups compared to the fluoride-free toothpaste group (p < 0.017).
