    Abstract PDF
    Objectives : The aim of this study is to evaluate the surface changes of enamel specimen,tooth structure by toothpastes in child and adult. Methods : Experimental teeth were collected from extracted human primary teeth. 120 enamelspecimens were prepared by cutting the teeth into 2 x 3 x 2 mm blocks using diamond sawand the specimens were assigned to 3 groups. Group 1 was used as control with no treatment. Group 2 was treated with child toothpaste and Group 3 was treated with adult toothpaste onprimary enamel surface for 3 minutes daily over 4 weeks. The specimens were immersed intoindividual container having artificial saliva and the artificial saliva was changed every day. Theelectron probe micro analyzer (EPMA) provided weight percent (wt%) of calcium (Ca) andphosphorous (P) on enamel surface. The morphology was analyzed by scanning electron microscopy(SEM). Data were analyzed by one-way analysis of variance (ANOVA) and Tukey’s test post-hoctest using SPSS (Version 20, SPSS Inc., Chicago, USA). Level of significance was set at 0.05. Results : The surface changes of the primary teeth revealed a significant difference during4 weeks. Calcium (Ca) and phosphorous (P) levels were found the weight percent differenceand a rough enamel surface was seen on SEM after adult toothpaste application. Conclusions : The changes in Ca and P and the morphological surface were affected bythe primary tooth treated with adult toothpaste. Enamel surface showed significant differencesduring 4 weeks.

    Abstract PDF
    Objectives : The purpose of the study is to examine the cell growth effect and autophagyeffect of Scutellariae Radix by ethanol extract in SCC 25 cells. Methods : Cell growth inhibitory effect and autophagy induced by Scutellariae Radix wereconfirmed by WST-1 assay, monodansylcadaverine(MDC) stain, and flow cytometry by acridineorange(AO) stain. Results : The Scutellariae Radix treatment decreased the cell proliferation in a dose and timedependent manner. Scutellariae Radix has anticancer effects that autophagic vacuoles were apparentby MDC and AO staining in SCC 25 cells. Conclusions : Scutellariae Radix showed anticancer activity against SCC 25 cells via autophagy. The data provided the possibility that Scutellariae Radix may potentially contribute to oral cancertreatment.
