Abstract

Introduction: Acidulated phosphate fluoride (APF) gels are commonly used as preventive caries materials in paediatric dentistry while glass ionomer cements (GICs) are widely used as a restorative material. The purpose of this study was to determine the effect of acidulated phosphate fluoride application towards the microhardness of GIC. Methods: This study was an experimental laboratory study where ten specimens were prepared from high viscosity GIC, which was Fuji IX. Specimens were stored in 50 ml distilled water at first 24 hours at 37°C, and then specimens were divided into fluoride group which was immersed in 25 ml of 1.23 % APF gel and control group which was stored 25 ml distilled water for 24 hours at 37°C. The Micromet II Microhardness Tester, Buehler, IL, USA that was standardised for Vickers hardness test was used to test the specimens at 100-gram load. Data were analysed using the t-test comparison test. Results: The level of microhardness of the fluoride group (14.34) was much lower compared to the control group (43.21) with a highly significant difference (p<0.01). Conclusion: The application of 1.23% APF gel on high viscosity GIC reduces the microhardness level compared to the control group.

Abstract

Seventy percent of children with cerebral palsy were found to suffer from speech articulation impairment. The purpose of this research was to obtain an illustration of speech articulation impair­ment in children with cerebral palsy tested by the Goldman-Fristoe method at the SLB-D School for Dis­abled Children Bandung in 2007. This was a descriptive research. Sampling was carried out by purposive sampling. The speech articulation impairment test was carried out on the basis of the Goldman-Fristoe method, that is, an articulation test which places the consonant at the beginning, middle, and at the end of a word, to test speech articulation impairment in children with cerebral palsy. Research results indicated that speech articulation impairment in the bilabial consonants /p/,/b/, and /m/ is the average 85.51%. Speech articulation impairment of the labiodental consonants /f/ and /v/ is an average 89.13%. Speech articulation impairment of the alveolar or dental consonants /t/ and /d/ is an average of 80.43%. Speech articulation impairment in the palatal consonants /c/ is an average of 82.60%. Speech articulation impairment in velar consonants /k/ and glottal consonants /h/ is an average of 86.96%. Re­search results indicated that more than three-fourths of children with cerebral palsy at the SLB-D School for Disabled Children Bandung in 2007 suffered from speech articulation impairment.

Abstract

Introduction: Oral habit is a bad habit that causes dental changes if habit are continued for long periods of time. Oral habit included digit sucking, lip sucking or biting, nail biting, mouth breathing. The purpose of study is to know the condition of oral habits in 7-15 years old homeless children undercare of Rumah Perlindungan Anak GANK (Generasi Anti Narkotika & Kriminalitas). Methods: This study was a descriptive research by survey technique. The sample consisted of 46 children collected by total sampling. Data pertaining to the study was collected through interviews in form questionnaire and clinical examinations.Result: The result shows that 71,74% have oral habits, consisting of 18 boys (54,54 %) and 15 girls  (45,45 %), out of which 26,09% homeless children have lip sucking or biting, 21,74 % have nail biting, 17,39 % have mouth breathing and 6,52 % have thumb sucking habit. Conclusion: Oral habit frequencyvwere most performed in homeless children was lip sucking or biting.

Abstract

Background: Garlic (Allium sativum L) is one of the most important Allium species consumed worldwide and has been used for decades as a cure for various diseases. The aim of this research was to compare the efficacy of single-clove garlic’s n-hexane and ethyl acetate fractions in inhibiting the growth of Streptococcus mutans biofilmMethod: This was a true experimental research. The biofilm mass was determined by absorbance value at 590 nm wavelength with ELISA reader in a microplate using safranin. Data was analyzed using ANOVA followed by post hoc analysis with ρ value <0.05.Result: The result showed that average decrease of biofilm mass after 1-30 minutes of ethyl acetate fraction administration was 33.4 ± 8.03 mg/mL, n-hexane 23.6 ± 0.97 mg/mL and chlorhexidine 35.5 ± 0.98 mg/mL. The average decrease of biofilm mass after 30-60 minutes of ethyl acetate fraction administration was 11.94 ± 7.44 mg/mL, n-hexane 43.87 ± 41.6 mg/mL and chlorhexidine 16.35 ± 4.6 mg/ mL. Statistic analysis showed that there was a notable difference in the decrease of Streptococcus mutans biofilm mass (ρ value= 0.00). Conclusion: The conclusion of this research was that administrating either n-hexane or ethyl acetate fractions of a single-clove garlic has the ability to decreaseS. mutans biofilm mass.
