Effects of nano-hydroxyapatite paste on enamel microporosity after bleaching treatment

Bleaching or teeth whitening is a popular dental conservative treatment to enhance aesthetics. Bleaching treatment in many cases has successfully improved aesthetics but still remains the side effects. It can cause some changes in enamel structure leading to demineralization characterized by the emergence of microporosity on the enamel surface. Nano-hydroxyapatite is potential to re-mineralize earlyenamel lesions. This study aims to identify the effect of nano-hydroxyapatite on enamel microporosity after bleaching treatment. Twelve rabbits were randomly divided into two groups. The control and treatment group administered a placebo and nano-hydroxyapatite paste respectively, for 7 days after bleaching treatment. Once the treatment was completed, the rabbit was sacrificed, the jaw was decapitated, upper and lower incisors of the rabbit were separated from the jaw. Subsequently, the sample preparation wasconducted for examination of enamel microporosity depth by using scanning electron microscope. The results showed the control group had more microporositycompared to the treatment group. The independent t-test result showed that enamel microporosityhad a significant value of 0.003 (p <0.05) meaning that enamel microporosity between both groups had a significant difference. The conclusion of this study was administration of nan-hydroxyapatite paste reduced enamel microporosityin the administration of nano-hydroxyapatite pastes compared to the placebo pastes after bleaching treatment

SHOE INSOLE FOR ECCENTRIC ACTIVITIES ON DAILY APPLICATION PREVENTS MUSCULAR DAMAGE AND IMPROVES FASTING BLOOD GLUCOSE

The eccentric contraction has been proven to improve Glut-1 expression in muscle and fasting glucose levels in mice. The same eccentric contraction occurs in human being when walking or running while wearing high heels. Innovation on the eccentric contraction with high heels can be done by using a specific shoe insole. The design of the rear insole is made thicker than the front. The purpose of this study was to determine the effects of insole use specified for eccentric activities on daily work shoes on the skeletal muscle damage after wearing the specified insole. Skeletal muscle damage was measured based on sTnI level. This was experimental study with pretest-posttest design. The subjects involved were non-diabetic woman workers in Faculty of Medicine of Universitas Airlangga, and were divided into two groups. Each group represented group members who wore 5-degree and 10-degree insoles respectively. The angle used for the shoe insoles were 5° and 10° respectively. These insoles were worn on weekdays for one week. Blood was taken one day after the subjects stop wearing the insoles. Data results showed that the levels of fasting blood glucose (FBG) of subjects who wore the 10-degree insole had a value of p<0.05. The use of insole lead to decreased levels of fasting blood glucose (FBG). This study found that the sTnI levels in the 5-degree and 10-degree insole groups had no significant effect on troponin I skeletal muscle levels before and after treatment

Altered Ghrelin Secretion Pattern and Sense of Hunger by Providing Low and High Density Breakfast in Obese Female Adolescents

Introduction: Ghrelin has been recognized to have a major influence on energy balance. Hence, the discovery of various regulatory factors that control ghrelin secretion may have major implications for the development of drugs and diet control. This study aims to analyze differences in ghrelin secretion pattern and prevention of hunger in the provision of breakfast in low-calorie breakfast, low energy density and high energy density in obese female adolescents. Methods: Subjects were female students aged 18-22 years with a BMI=25 kg/m², receiving low-calorie breakfast with low (n=8) and high energy density (n=8). Before the breakfast, subjects fasted for 12 hours and were subjected to plasma ghrelin level and hunger measurement using visual analog scale (VAS). Breakfast was done at 08.00, divided into three parts and each was taken for 5 minutes. Measurement of plasma ghrelin was carried out again post prandial (PP) at 2 hours and 4 hours. VAS filling was done 1 hour PP, 2 hours PP, 3 hours PP, and 4 hours PP. Result: There were differences in plasma ghrelin level, but not significant. VAS 1 analysis of hunger (p=0.040) at 4 hours PP and VAS 3 of satiety (p=0.025) was significantly different at 3 hours PP. Conclusion: Food density did not affect the plasma ghrelin levels. Low density foods are more effective to prevent hunger in 4 hours PP and increases satiety in 3 hours PP
