Background: COVID-19 has been regarded as a new pandemic in the world. This disease is highly contagious and can be transmitted easily through droplets and air. This matter is considered as a red flag to all dentists all over the globe. Until today, there is only a few specific guideline in regards to dental practice during and after the pandemic. The protocol only revolves around the limitation of patients’ appointments and using level 3 personal protection equipment. There is no specific mention on the preparation method of the practice room especially in Indonesia. Purpose: This study aims to review literature on infection control in dental settings during COVID-19 pandemic and discuss possible recommendations based on available evidence. Review: The review also discussed the background of COVID-19, transmission, clinical findings, physicochemical properties, and cross infection in dental practice. Despite the usage of personal protective equipment, the rooms need to be set to specific requirement to reduce contamination inside the room. Until today, COVID-19 transmission must be prevented with the best method available. Conclusion: No single protocol may fully guarantee the safety of the patients and dental workers. We suggest to combine the protocol listed above to minimize to self and cross-contamination ’new normal’ practice.
Introduction: SThe carbonated beverage is the main factor causing tooth erosion due to acidic and mass consumed, especially by children and adolescents.Purpose: This study was conducted to determine the differences between solubility of calcium in deciduous teeth and permanent teeth in the soaking fruit-flavored carbonated beverage.Methods: The research was a quasi experimental research with the formulated research post test only design. The sample used was 24 teeth, which consists of 12 deciduous incisors central teeth of the maxillary and 12 incisor central permanent teeth of the maxillary. The samples were divided into 6 groups and treated by soaking in the carbonated soft drinks for 30, 45, and 60 minutes. The data analysis used in this reasearch was a Two Way ANOVA test with probability p<0.05. Furthermore, the data were analyzed by the Tukey HSD test to determine the differences in each group.Results: Based on Two Way ANOVA test that was conduct, it was obtained significance value of 0.000 (p <0.05), so it can be concluded that there are significant differences between groups. From Tukey HSD test it was obtained a significance value of p<0.05 in all groups. It means that there are significant differences between each group, except in the immersion group of deciduous teeth 30 minutes with the permanent teeth 45 minutes that obtained 0,929 significance (p>0.05). It means that there was no significant differences between the two treatment groups. The result of the data analysis reveals that there was a difference in the solubility of calcium in deciduous teeth and permanent teeth. The solubility of calcium in deciduous teeth was larger than the permanent teeth at all time duration, because of the deciduous teeth had thinner and permeable enamel than permanent teeth.
AbstracPropolis is a compound present in honey produced by bees and used for the treatment of wounds as it has anti-bacterial and anti-inflammatory effects. The use of propolis in the field of dentistry is still in the research process. The purpose of this study was to determine the effect of gel contains propolis 10% on healing of Gingivitis. Fifty four male Sprague Dawley rats are used as a modelsof gingivitis. Gingivitis rat models were randomly divided into three groups. The first group as positive control group treated with aloe vera gel, the second group as negative control grouptreated with CMC-NA gel, and the third group as treated with propolis 10% gel. Gel application in each group carried out two times a day on days 1,2,3,5,6, and 7. Gingival tissue samples be taken after 24 hours of treatment every day in each group for histological preparats. Hematoxyline Eosin (HE) staining was done to examine neutrophil cells, fibroblasts, and angiogenesis. Data were analyzed using the parametric statistical tests Two-way Anovaand LSD (Least Significant Difference).The results showed that gel propolis10% have the same level of effectiveness with aloe vera gel in reducing significantly the number of inflammatory cells of neutrophils on day 2 and 3 compared with negative controls (P <0.05), increases the number of fibroblasts cells on day 5 and increases the number of new blood vessels significantly on day 5, 6, 7 as compared to the negative control. Propolis 10%-gel have the same effectiveness with aloe vera gel in order to increase the number of fibroblast cells on days 5 and 6.Propolis 10%-gel effective as a topical drug in healing process of gingivitis through the reduction the number of inflammatory cells of neutrophils, increases the number of fibroblasts cells and the formation of new blood vessels (angiogenesis).
Background: One of factor that increases the flexural strenght of fiber reinforced acrylic resin is a fiberglass position . Fiberglass is one of type that can be used in dentistry. The aim of this was to determine the influence of position of fiberglass to the flexural strenght of fiber reinforced acrylic resin. Method: This study was in vitro laboratory experimental. Samples was 16 plate spesimens (65x10x2.5mm). The study group was divided into 4 group : 3 groups of fiber reinforced acrylic resin were given fiberglass at the upper, middle, and bottom side and 1 control group of resin acrylic without fiberglass. All of groups would be in the flexural strenght test with a three-point bending test using a universal testing machine. Result: Based on One Way ANOVA test showed that there were significant value 0.000 (p<0.05), it concluded that there were significant influence between all the groups. Based on the LSD Post Hoc test showed that there were significant value between all of groups with fiberglass reinforced and control group without fiberglass reinforced. Comparisson between the group that given fiberglass in a upper and middle side with the group that given in bottom side showed value of significant difference (p < 0.05). Conclusion:The result of study was concluded that there was an influence on the position of fiberglass to flexural strenght of fiber reinforced acrylic resin
