Abstract

Periodontitis is one of periodontal disease that the main cause is bacteria, especially Actinobacillus actinomycetemcomitans (AA). One of the treatments for these conditions can be done with subgingival irrigation using Gambir catechin (Uncaria gambir [Hunter] Roxb). Catechins are polyphenolic compounds and have antibacterial effects. Based on its advantages, a cathecin effect may decrease the amount of AA in periodontitis and help the healing. The aim of this study was to know the effect of subgingival irrigation of the Gambir catechin to the amount of AA in periodontitis mice. Twelve mice, 3 months age, 200-250 gr in weight, with the anterior gingival sling with yarn was made for periodontitis condition. The mice were divided into four groups treatment: Treatment with aquadest, Gambir catechin I, Gambir catechin II, and chlorhexidine 0.2%. Subgingival irrigation performed after visible signs of periodontitis with 2 times daily for seven days. AA retrieval was done using paper points inserted in the gingival sulcus and grown in BHI agar with bacitracin 5 units/ml (modification). The number of AA was then counting with colony counters. Study result showed a significant difference (p <0.05) between aquadest treatment group with Gambir catechin I, Gambir catechin II, and chlorhexidine 0.2%. But there was no significant difference between Gambir catechin I and II. The conclusion of this study indicated that subgingival irrigation of Gambir catechin I and II could decrease the amount of AA but there was no statistical difference between the two groups. This means that Gambir catechin in solutions and effervescent didnt affect the activity of a substance in it. It was shown that catechins can be used as an alternative to the condition of periodontitis.

Abstract

According to the Data and Information Centre of the Ministry of Health of the Republic of Indonesia (2018), the prevalence of caries in Indonesia is 88.8%. The World Health Organisation (WHO) reports that 60-90% of school children worldwide experience caries, with the disease being most prevalent in children aged 6-12 years. Dental caries is a disease that can infect and damage tooth structure. One of the risk factors for caries is plaque accumulation, which is associated with poor oral hygiene. The Personal Hygiene Performance Modified (PHP-M) is a method used to measure plaque on mixed teeth. This research is a quasi-experiment with a one-group pretest-posttest design. The sampling technique used was purposive sampling, with a total of 27 samples meeting the inclusion and exclusion criteria. The study found a significant improvement in oral hygiene status after participants received an educational intervention using virtual reality video media. Specifically, there was a decrease in plaque scores after brushing teeth following the intervention compared to before. The statistical analysis using the Wilcoxon test showed a significant difference with a p-value of less than 0.05. The study found that the number of students with excellent oral hygiene status increased from 15 (40.5%) before the intervention to 36 (97.3%) after the intervention. These results suggest that the use of virtual reality video media is an effective method for improving oral hygiene.

Abstract

ABSTRACT Introduction: The utilization of applications as a tool for the calculation of dental and oral health indices has not yet been extensively explored. Consequently, researchers have proposed the development of the digital dental calculator application as a rapid and precise medium for the administration of oral health index surveys. Aim of this research is to analyze the use of digital dental calculator apps as an OHI-S calculation tool. Methods: The study design is quasi-experimental with a posttest-only group design. Convenient sampling was employed as the sampling technique, and the selected samples fulfilled the inclusion and exclusion criteria. The inclusion criteria were students of the dental profession at Baiturrahmah University, Indonesia, who were still enrolled in or had passed the periodontics module, while the exclusion criteria were students who did not participate in the full study (manual and digital). Results: The mean time taken to calculate OHI-S calculation results manually was 207.63 seconds, while the mean time taken to calculate the same results using the digital dental calculator application was 67.97 seconds. The results of the Mann-Whitney test indicate that there is a highly statistically significant difference between manual and digital calculations using the application, with a p-value of 0.000 (<0.05). Conclusion: There is a time difference between the use of digital and manual calculations for OHI-S calculations. The findings of this study indicated that the time required to perform OHI-S calculations using digital dental calculator applications was significantly shorter than that required for manual calculations.KEYWORDSoral hygiene index simplified (OHI-S), time duration, digital dental calculator

Abstract

Diarrhea is a state of defecation more than 3 times day accompanied by liquid stool in a 24-hour period (World Health Organization). The incidence of diarrhea in Indonesia is the number 2 cause of death in children under the age of 5 years. The knowledge possessed by a person, especially mothers, greatly influences the attitude of mothers in overcoming diarrhea in toddlers, because it is likely that diarrhea prevention measures at home by a mother are influenced by maternal knowledge, the better the mother's knowledge, the better the action against diarrhea prevention (Fani, 2020). So researchers are interested in examining the picture of maternal knowledge about diarrhea prevention in toddlers. This study aims to determine the picture of maternal knowledge about diarrhea prevention in toddlers in Neighborhood Association 02 Citizinens Association 03 Becirongengor Village. Analytical descriptive research design. The number of respondents was 40 mothers. This research will be conducted on January 16 – March 17, 2023. Assessment of the mother's picture of knowledge about the prevention of diarrhea in toddlers using questionnaires. Most mothers have sufficient knowledge of 30 people (75%), this shows that mothers have not been able to know about the prevention of diarrhea in toddlers properly and correctly. Due to the unclear receipt of information from competent health workers, it is difficult to receive information. The conclusion of this study is that the description of maternal knowledge about the prevention of diarrhea in toddlers in Neighborhood Association 02 Citizinens Association 03 Becirongengor village is mostly sufficient.
