Abstract

The purpose of this study was to evaluate the microorganisms found on used toothbrushes. In this study 25toothbrushes were investigated, 10 toothbrushes were used less than 3 months, 10 toothbrushes have been used for3-6 months, and 5 toothbrushes have been used for more than 6 months. Some gram-positive coccus, such asStaphylococcus, Streptococcus and Diplococcus. The results showed there were microbial harbored of usedtoothbrushes. Toothbrushes that have been used for 6 months were harbored more microorganisms than thetoothbrushes that have been used less than 3 months and 3-6 months. It can be concluded that the longer using timeof toothbrush the more increase of microorganism amount found on toothbrush.

Abstract

Objective: Many patients suffer from sensitive teeth after bleaching that can cause demineralization of enamel and widening of dentinal tubules. Hence, researchers are looking for natural ingredients for enamel remineralization material include chicken egg shells because it contain calcium carbonate that can restore lost inorganic compounds. This study aimed to identify inorganic compound in eggshell as dental remineralization agent.Materials and methods:This study was an experimental laboratory with with post test only control group design. The research sample was five maxillary central incisor that has been applied with 35% hydrogen peroxide bleaching material in different time range 1 hour, 1 hour 30 minutes, 2 hours, 2 hours 30 minutes and 3 hours. Then, samples were applied with chicken egg shells gel for 14 consecutive days. Identification of inorganic compound was analyzed using Energy Dispersive X-ray Spectroscopy (EDS).Results: The application of chicken egg shells gel do not cause a significant difference in the composition of enamel compound between control group and treatment group.Conclusions: There is an increasing number of inorganic compounds in samples that had been applied with eggshell gel such as calcium, phosphorus, magnesium, chlorine, oxygen, and aluminium.

Abstract

Objective: Carbamide peroxide 10% is commonly used in home bleaching procedure. Effectiveness of carbamide peroxide bleaching process as a home bleaching has no successor yet, but its use is still being debated due to the effects on oral cavity. Strawberries are one of natural ingredients that currently used to whiten decolorized teeth because it contains ellagic acid and malic acid. On contrary, malic acid is said to be involved in the process of erosion. The aim of this study was to compare tooth enamel hardness after application of dental bleaching agent carbamide peroxide 10% and strawberry gel.Material and Methods: Sample consists of 30 maxillary incisors were divided into 3 groups. The first group as control soaked in aquades. The second treatment group were applied with carbamide peroxide 10%  and a third group applied with strawberry gel. Before and after the sample application, tests were performed to determine the hardness of tooth enamel as measured using Universal Hardness Tester.Results: Based on Friedman test, p-value = 0,000 (p <0,05; significant). This means that there was a significant difference in tooth enamel surface hardness of each group and treatment group using bleaching carbamide peroxide 10% and strawberry gel.Conclusion: There was a decrease on tooth enamel hardness after application of carbamide peroxide 10%  compared strawberry gel.
Comparison of blood clam (anadara granosa) shell paste, shrimp (litopenaeus vannamei) shell paste and casein phosphopeptide-amorphus calcium phosphate (CPP-ACP) paste as teeth remineralization material Asmawati Asmawati; Bahruddin Thalib; Alqarama M. Thalib; Delvi S. Reni; Rafikah Hasyim

Abstract

Objective: The aim of this study was to determine the comparison of blood clam (anadara granosa) shell paste, shrimp (litopenaeus vannamei) shell paste and casein phosphopeptideamorphus calcium phosphate (CPP-ACP) paste as teeth remineralization material.Material and Methods: This study was an experimental laboratory with cross sectional design. Study sample was 15 maxillary central incisors that were applied with 35% hydrogen peroxide for 2 hours, then assessed with Energy Dispersive Spectroscopy (EDS). Samples were divided into 3 groups: 5 samples were applied using blood clam (anadara granosa) shell paste, 5 samples using shrimp shell paste and 5 samples were applied using CPP-ACP paste every 8 hours for 14 consecutive days then checked with EDS. Data analysis using SPSS test independent t-test to see comparison of blood clam (anadara granosa) shell paste, shrimp (litopenaeus vannamei) shell paste and casein phosphopeptide-amorphus calcium phosphate (CPP-ACP) paste as teeth remineralization material.Results: The result of this study showed P> 0.05 which means there was no significant difference between blood clam shell paste, shrimp shell paste and CPP-ACP mineral composition.Conclusion: Blood clam shell paste and shrimp shell paste has an effective value to be used as tooth remineralization material.

Abstract

Objective: This study aims to determine differences in the value of calcium, phosphor, and alkaline phosphatase in the blood of bone graft material which is applied to bone defectsMethods: 12 male rabbits were divided into 4 groups, then defects were made in the femur bone with a diameter of 5mm. then each group was drawn with a vulnerable blood pre-operative time, 1 week, 3 weeks, and 6 weeks after surgery.Result: Average levels of calcium, alkaline phosphate and phosphorus in all treatment groups were higher than those in the control group.Conclusion: There were differences in calcium levels in test animals using bone graft α-calcium sulphate hemihydrates bioceramic on days 7th, 21st, and 42nd post surgery.
