This study aimed to evaluate the effects of epoxy resin and calcium silicate-based root canal sealer on fiber post adhesion strength. Thirty single-rooted lower premolars were divided into three groups (n = 10 for each group): Group 1, no root canal filling; Group 2, epoxy resin root canal sealer; and Group 3, calcium silicate root canal sealer. After all teeth were prepared with rotary instruments, Groups 2 and 3 were filled with gutta-percha points and root canal sealer. A fiber post was cemented in all tooth, then 2-mm disc samples were taken from the middle root section and subjected to a push-out bond strength test. Data were analyzed using one-way ANOVA and Bonferroni test. The highest average adhesion strength was exhibited by the control group (57.142 ± 12.205 MPa), followed by the epoxy resin group (44.455 ± 10.347 MPa) and then the calcium silicate group (28.009 ± 9.562 MPa). There was a significant difference in push-out bond strength between the groups (p < 0.006). The teeth that were endodontically treated with epoxy resin root canal sealer exhibited better fiber post adhesion strength compared to the teeth that were treated with calcium silicate root canal sealer.

In order to avoid diseases that can affect reproductive organs, Menstrual Hygiene Management (MHM) needs to be implemented. This study aims to assess MHM and the determinants of junior high school female students at Tinambung sub-district. A quantitative approach with a cross sectional design was conduct towards 250 female students proportionally random selected from 3 junior high schools at Tinambung sub-district. Data were collected online using a questionnaire and analyzed using chi square test and multiple logistic regression. A number of 60.8% of female students practiced poor MHM. Female students who had negative attitude towards MHM had almost 8 times the chance to practice poor MHM compared to students who had a positive attitude after being controlled by knowledge on MHM, water facilities, sanitation and hygiene (WASH) at school, education of mother and exposure to information (P= 0.005, OR: 7.98, 95% CI: 3.91, 16.29). Efforts are needed to provide information related to MHM through mothers, teachers and social media which are now widely accessed by students as well as improving WASH facilities at schools to support female students practice adequate MHM.

Odontogenic cysts and tumors are aspects that often discussed and quite important in the field of either oromaxillofacial surgery or pathology. Radiographically, the dentigerous cyst, odontogenic keratocyst (OKC), and unicystic ameloblastoma have a similar appearance in the form of unilocular radiolucent lesions. As a results of histopathological examination with hematoxylin eosin staining, these three lesions can be distinguished, however, many pathologists are misdiagnosed because of their similarity. Calretinin is a calcium binding protein that has been widely used for markers of malignancy in human tissues, due to its role in cell apoptosis which causes cell proliferation. This study aims to observe and compare Calretinin expression in dentigerous cysts, OKC, and unicystic ameloblastoma. 34 paraffin blocks of dentigerous cysts, OKC and unicystic ameloblastoma were obtained by consecutive sampling from medical record data in the Cipto Mangunkusumo Hospital, Oral Surgery Division which had confirmed histopathological results at the Department of Anatomical Pathology Cipto Mangunkusumo Hospital during the period 2015-2019. All samples were subjected to immunohistochemical staning using mouse monolclonal Calretinin antibodies. 13 samples of dentigerous cysts, 6 samples of OKC, and 15 samples monoklonal of unicystic ameloblastoma were obtained. The positive interpretation of Calretinin was 1 sample of dentigerous cyst and 11 samples of unicystic ameloblastoma. Using Chi-square test value of significancy was 0,001 with odds ratio 49,5 (95% CI = 4.88 to 501.7). Calretinin was expressed in dentigerous cysts and unicystic ameloblastoma with different percentages, but not in OKC. Calretinin can be used as a marker for unicystic ameloblastoma Experimental article (J Int Dent Med Res 2021; 14(3): 965-969)
Vitamin D levels are associated with improved immunity dysregulation to prevent worsening of COVID-19 patients. However, studies regarding the effects of vitamin D on COVID-19 patients are still inconsistent. This study aimed to analyze vitamin D supplementation's effect on the severity and mortality risk of COVID-19 patients. Search was conducted in seven databases on September 2020. Studies assessing the topic were included without study design restrictions. Four studies were included in this study. All reported risk of mortality, and three reported of severity degree. Two of the three found patients with vitamin D supplementation had a significantly lower risk of disease. One other found no significant difference, although a higher proportion of severe COVID-19 was recorded in the group without supplementation. Three of the four reported supplementation as a protective factor against mortality in COVID-19 patients. One study reported that vitamin D supplementation group had a higher mortality than the group without, although it has low validity and high risk of bias. In conclusion, there were differences in the severity and mortality risk between COVID-19 patients given vitamin D supplementation and control patients. Vitamin D supplementation is a protective factor in the severity and mortality risk of COVID-19 patients. © 2021, Journal of International Dental and Medical Research, All Rights Reserved.
The COVID-19 has spread globally and ensued several global restrictions with consequences of unknown long-term proportions, currently placing a strain on the healthcare system worldwide. This review aims to present the role of dentists in the COVID-19 pandemic in various aspects of dentistry, including general dentistry and restorative dentistry. Various studies and reports on COVID-19 were analyzed. Literatures on 2019 novel coronavirus disease (COVID-19) were explored using key words “COVID-19”, “COVID”, “dentistry”, “oral health”, “oral cavity” in Google Scholar, PubMed/Medline, and Scopus databases. It was found that dentists, dental specialists, dental assistants, dental staff, and patients are potentially at higher risk of COVID-19 infection during dental treatments. There is an association between the oral cavity and systemic diseases in the context of COVID-19 disease caused by SARS-CoV-2 virus. There is a great role of dentists in the COVID-19 pandemic in various aspects of dentistry, including general dentistry and restorative dentistry © 2021, Journal of International Dental and Medical Research.
