Anxiety is a psychological and physiological condition which signed by emotion, cognitive, and someone’s behavioral component. Anxiety behavior has long been recognized as the most difficult aspect in the management of patients and may frustrate a dental treatment that will be carried out, especially in children ages 6-12 years. Fear of treatment tooth extraction and local anesthesia is the main reason for kids disliking dental care. This type of research is observational analytic with nonprobability sampling technique, because this study used a population of pediatric patients who visited the location of the research that has been determined. Total sample of this research are 30 people who fulfill the criteria. The sample consist of 16 boys and 14 girls with age range of 6 to 12 years old. The level of anxiety before and after tooth extraction assessed using Facial Image Scale (FIS). Facial Image Scale (FIS) has five criteria which describe the level of anxiety in children, very happy by point 1, happy by point 2, normal by point 3, unhappy by point 4, and very unhappy by point 5. The results of the analysis of differences in anxiety with FIS measurement tools show there are differences in the level of anxiety in children before and after tooth loss based on the location of the jaw, the type of anesthesia applied topically, gender, and overall. Overall, there is a difference in children before and after tooth loss and the difference is significant
Natural resources that can be used as natural antibacterial are coriandrum sativum L. which contains linalool and phenol as antibacterial ingredients. Material and Methods: Samples of bacteria were staphylococcus aureus taken from four children who had angular cheilitis. Extraction of coriandrum sativum L. using maceration method with ethanol solvent. Positive control group was given vancomycin, the treatment group was given extract of coriandrum sativum L. concentrations of 0.1%, 0.2%, 0.4%, 0.8%, 1%, 2% and 4% were incubated 24 hours. Then the inhibitory zone measurements are carried out using a caliper. Results: The study showed extract concentrations of 0.1%, 0.2% and 0.4% did not show any inhibition. The concentration of 0.8% inhibition zone was only seen in the second sample (14.3 mm). The first 1% sample concentration (7.94 mm), the second sample (8.43 mm), the third sample (8.61 mm) and the fourth sample (7.77 mm). The first 2% sample concentration (8.18 mm), the second sample (8.61 mm), the third sample (8.64 mm) and the fourth sample (8.34 mm). The first 4% sample concentration (9.24 mm), the second sample (9.37 mm), the third sample (8.81 mm), and the fourth sample (8.77 mm). Vancomycin (21.3 mm) while the negative control did not show any inhibition, then the data was tested using the Kruskal Wallis and Mann Whitney Test (p<0.05). Conclusion: There is a difference in inhibitory power in each treatment and the 4% concentration that is most effective in inhibiting staphylococcus aureus.
To investigate the possibility of smart handpiece for controlling dental rotational instruments using the voice command system. Material and Methods: This smart handpiece has a battery that can be used directly using AC 220V power supply. On the handpiece, a sound sensor that can recognize sound is provided. This sound sensor can receive commands to adjust the rotation speed of the handpiece, adjust the water and wind are released by the handpiece. In order for the tool to work properly we use a microcontroller to be able to carry out its functions when the sound sensor receives signals. Next the microcontroller will execute the programmed commands such as the voice command that can turn on the compressor to adjust the motor rotation and water output on the handpiece out its functions when the sound sensor receives signals. Next the microcontroller will execute the programmed commands such as the voice command that can turn on the compressor to adjust the motor rotation and water output on the handpiece. Results: According to our study, the smart handpiece can work well with the voice command system. Conclusion: A novel smart handpieces provides promising prospects for use in dental practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
