Knowledge in the field of oral health provides an understanding of how to do maintenance and prevention of dental and oral diseases. Teachers can act as a source of information for students so that they are expected to have sufficient knowledge about dental and oral health applied in the UKGS program. The purpose of this study was to find out how the level of oral and dental knowledge in teachers and students in primary schools with UKGS and without UKGS. The type of research is descriptive. The sampling technique used total sampling method with total research subjects that fulfilled inclusion criteria of 39 teachers and 80 students, consisting of 24 teachers and 64 students in SDN 16 (UKGS) and 15 teachers and 16 students in SDN 46 (without UKGS). Measurement of dental and oral health knowledge was done by using questionnaire. The results showed that the level of knowledge of dental and mouth health of teachers and students at SDN 16 (UKGS) and SDN 46 (without UKGS) had good category with 87.5% percentage for teachers and 82.8% for pupils in SDN 16 (UKGS ) and 80% for teachers and 68.8% for students in SDN 46 (without UKGS). Keywords: UKGS, knowledge, teachers, students

Covid-19 pandemic has directed hospitals to concentrate services for patients who are positive or still in undefined status. Some countries are even forced to build temporary structures or utilize multifunctional buildings such as sports/public halls. On the other hand, hospitals still have to keep performing other routine services and this becomes a challenge for them. When global attention nowadays focuses more on how hospitals serve the Covid-19 cases, this research proposes another side of healthcare service needed by people in the pandemic, which is the dental clinic. The spread of Covid-19 through droplets puts both dental patients and practitioners at risk target of Covid-19 transmission. Therefore, particular standards and protocols are mandatory to be deployed. A prototype design of the temporary dental clinic is the main output from this research. The main objective is to provide service for the community without being afraid of contracting the pandemic as the clinic will be isolated from the regular hospital buildings. To achieve this objective, this research employed three approaches for the methodology. It was started with the desk study to review references on recent technology of temporary building structures. Followed by the online questionnaire using the Google platform distributed to 206 registered dental practitioners in Aceh, in collaboration with the Indonesian Dental Association, Aceh Province, Indonesia. The questionnaire collected the data related to the needs, standards, procedures, and dental service protocols under the Covid-19 pandemic as the main reference for the design process. The last approach was gathering feedback from dentists and international architects who are experts in building science and technology. This was done through a series of pre-design reviews. This research has a high degree of urgency globally, including Saudi Arabia, which is also impacted by the Covid-19 pandemic. It is also in line with Saudi Vision 2030 to enhance the standard quality and sustainability of healthcare services. The prototype design proposed in this research does not only contribute to the Covid-19 pandemic in particular but also post-Covid scenarios or other possible global pandemics in the future.

Introduction:Loss of teeth is a condition where one or several teeth are lost from the socket. Loss of one or several anterior teeth can cause esthetic disruption, loss of confidence, concerns about appearance, and lost function of the teeth, thereby greatly affecting an individual's mind and activity. The loss of some or all of the teeth has many impacts, one of which is the emotional impact. Emotional impact is a feeling or assessment reaction that is derived from the nervous system in response to stimuli from the outside or inside due to loss of teeth, which is known through the categories affected, avoidance, depression, irritability, embarrassment, and feeling old.

Background: Oral squamous cell carcinoma (OSCC) is one of the most common oral cancers with a high mortality rate. The biodiversity source in Indonesia makes areca nut a potential antioxidant in treating disease. Objective: The study aimed to evaluate the chemotherapeutic effect of areca nut extract in 4-nutriquinoline-1-oxide (NQO)-tumor-induced rats. Methods:  Twenty-eight male Sprague-Dawley rats were divided into four groups. Group 1 served as the control group, group 2 was 4NQO-induced rats without treatment, and groups 3 and 4 were given 4NQO-tumor inducer with 500 and 1000 mg/kg BW of areca nut extract, respectively. The rats in groups 2,3, and 4 received 30 ppm of 4NQO tumor inducer in drinking water for 12 weeks. In the end, all rats were euthanized and the tongue was removed. The body, liver, kidney, heart, and lungs weights were measured. Tongue tumor volume and dysplasia lesions were analyzed. The tumor-infiltrating lymphocytes (TILs) in the tumor and stromal area were scored semi-quantitatively associating the infiltrate grade (0-3) and analyzed histologically. Results: There were significant differences in body weight loss between the initial and final phases in groups 1 and 2 (p<0.05). The areca nut at doses of 500 and 1000 mg/kg BW significantly reduced the tumor size compared with groups 1 and 2 (p<0.05). The incidence of OSCC in rats with 500 and 1000 mg/kg BW of areca nut extract after 22 weeks was 0%, but the dysplasia lesions were observed at 28.57% and 85.71%, respectively. The highest mean of stromal TILs was in group 3 and there were significant differences in stromal TILs between groups 2 and 3 (p<0.05). Conclusion: Areca nut extract exerts a chemotherapeutic activity in 4NQO-induced rats by inducing infiltrating lymphocytes in the stromal tumor area on the OSCC lesion of the tongue.

Introduction, loss of teeth can cause problems with mastication, speech, aesthetics, social activities, inhibit work performance, and daily activities. Causes of tooth loss include trauma, caries, periodontal disease, infection, orthodontic treatment, and knowledge. Knowledge can influence a person & attitude.Therefore, this study aimed in cross-sectionally assessing the relationship between knowledge and attitudes of Syiah Kuala University students’ batch 2018 about the impact of tooth loss. Methods, cross-sectional study design was used in this study, involving 384 subjects, with cluster sampling technique. The results showed knowledge about the impact of tooth loss was 80.1% and attitudes about the impact of tooth loss were 79.5%. The correlation coefficient shows a positive correlation value between the knowledge and attitude variables which shows a significant level (p & lt; 0.01). Conclusion, there is a relationship between the knowledge and attitudes of Syiah Kuala University students batch the 2018 about the impact of tooth loss.
