this investigation was carried out to verify the mechanical efficiency of a sugar-free chewing gum on dental plaque removal. Fifty (6.12 yr old) children were used. Firstly they receveid a dental prophylaxis and were instructed to not clean their teeth for 4 days. Following this period, they were examined for the IHOS (The simplified oral higiene index) recording and received 5 chewing gum tablets to chew during 15 minutes at one hour intervals, After chewing the IHOS was again obtained. Statistical analysis of the difference of data obtained before and after chewing showed the sugar-free gum as effective for plaque removal, at a 5% significant level.

ABSTRACT Objectives: To study the effect of water, halloumi cheese and sugar-free (SF) chewing gum on plaque pH recovery after the intake of sweetened PLAs. Settings and Design: A randomized clinical trial was conducted on 17 children (10 females, 7 males) aged 11–12 years with DFT/dft of more than 3. Materials and Methods: Each volunteer tested paracetamol and ibuprofen suspension alone or followed with water, halloumi cheese or SF gum, as well as 10% sucrose and 10% sorbitol as controls. Plaque pH was measured using the sampling method before and after 5, 10, 15, 20, 30 min of ingestion. Statistical Analysis: Statistical analysis was performed using analysis of variance followed by least significant difference test to assess minimum pH (min pH), maximum pH drop (ΔpH), and the area under baseline pH, and P value was set as 0.05. Results: Both ibuprofen and paracetamol were not significantly different from 10% sucrose in terms of min pH, ΔpH, and area under baseline pH except for min pH of ibuprofen (P = 0.034). Water and halloumi cheese did not have a significant effect on plaque pH recovery after the intake of both analgesics as min pH, ΔpH, and area under baseline pH were similar to 10% sucrose except for min pH of ibuprofen + water (P = 0.048). However, plaque pH variables after chewing SF gum for 20 min were similar to 10% sorbitol. Conclusion: Chewing SF gum immediately after the intake of sweetened PLAs for 20 min restores plaque pH and could be recommended as a complementary aid in caries prevention.

This report deals with the influence of the self-fulfilling prophecy on dental prophylaxis. The aim was to test if this phenomenon had any influence on the treatment of patients, they and their therapeutist's perception of each other and the result of the prophylactic work. Sixty patients and 34 students were involved. The patients were randomly classified as “good” or “bad”. Twenty-seven students had a patient from each group. Dental plaque and gingival inflammation were recorded before and after the treatment. No difference in improvement between the two groups could be shown. Both patients and students were interviewed about their experiences and feelings during the treatment. All patients were satisfied with their therapeutist. The students generally accepted the classification although they were made aware of the self-fulfilling prophecy. This was confirmed by a significantly higher frequency of patient drop-outs, broken appointments and critical notes about the patients in the “bad” group compared to the “good”. The conclusions are that the self-fulfilling prophecy can be initiated by even minor notes in patient files, and that this affects the treatment of patients.

Dental plaque removal is an important issue in health promotion. Toothbrushing is one of the main methods employed for such purpose, since it can prevent dental caries by means of the fluoride present in the dentifrice. Dentifrices might contain plaque disclosing agents and thus allow dental plaque observation. The aim of this study was to assess whether utilization of a plaque disclosing agent interfered with plaque removal among adolescents, as well as the difference between utilization of erythrosine tablets and dentifrices containing plaque disclosing agent. The sample was composed of 62 students from Piracicaba, SP, Brazil, aged 12 to 14 years old, divided into 3 groups: G1 or control group (toothbrushing without plaque disclosure); G2 (plaque disclosing with an erythrosine tablet and toothbrushing) and G3 (toothbrushing with dentifrice containing plaque disclosing agent). After toothbrushing, disclosure of the remaining dental plaque was performed in all groups with a fuchsin tablet and measured through the Simplified Oral Health Assessment Index (OHI-S), in two stages with a 2-month interval between them. The analysis of variance (ANOVA) showed that there was no difference in the OHI-S index between the groups (p>0.05), however the G3 displayed a higher proportion of students with plaque reduction (23%) than G2 (21%), besides the smallest difference in the mean remaining dental plaque. There was no difference between groups; however, it was suggested that the dentifrice with plaque disclosing agent had positive results in relation to the erythrosine tablet, even though the small sample size may have interfered with the results, indicating the need of complementary studies.

Abstract Dental plaque is formed from biofilm that coats the surface of the teeth and is an indicator of dental and oral hygiene. One way to control plaque is by brushing your teeth. Herbal toothpaste is expected to inhibit plaque growth because it is related to the ability of herbal ingredients to inhibit microbial growth. This study aims to determine the comparison of the effectiveness of herbal and non-herbal toothpaste on reducing the plaque index in children aged 15-18 years (WHO). This type of research is  experimental with pretest-postest group design on 30 respondents obtained by total sampling method and divided into 2 groups. A total of 15 respondents in the first group used herbal toothpaste and 15 respondents in the second group used non-herbal toothpaste. The plaque index is measured based on the Loe and Silness plaque index. Paired t test was used to determine the difference in dental plaque index before and after treatment. The results showed that there were significant differences in the dental plaque index on the use of herbal and non-herbal toothpaste for children aged 15-18 years. Keywords: plaque index, herbal toothpaste, non herbal toothpaste

Objectives: This study is designed to statistically analyze data of outpatients visiting for recent 3 years. The purpose is to identify tendencies of patients who visit the hospitals before and after COVID-19. Methods: This study retrospectively analyzed the medical records of 452,487 patients who visited to the Daejeon·Cheonan·Cheongju Korean Medicine Hospital of Daejeon University from January 1, 2018 to August 31, 2020. The data is classified according to year, month, gender, age, and visit type. The statistical analysis was performed using IBM SPSS 25.0. Results: The total number of patients decreased in 2020 compared to before 2020, and the number of patients in each hospital also decreased from the previous year. According to the year of each hospital, the difference by year was not statistically significant at Daejeon Hospital, but Cheonan and Cheongju Hospital showed statistical difference. The change in monthly according to the year by hospital has continued to decrease from January to March in 2020, unlike the previous year, which recovered from a decline in March. In the analysis of patients by age, there was no statistically significant difference in the number of patients in the above 60s according to the year, while those under 60s have a tendency to significantly decrease.. Conclusion: We expect that the results of this study will be used as reference materials in analyzing effects of COVID-19 at health care utilization.

The article deals with chemical properties of honey as well as wax and beeglue before and after the process of caramelization. The research has been done to study chemical reactions of caramelization of honey and other bee products; the biochemical properties of the obtained substances have been investigated as well. It has been revealed that biological activity of the compound after thermochemical heating of honey in the presence of special catalysts was discovered. Infrared spectra, moisture, viscosity, size and distribution of nanoparticles, elemental composition, oxymethylfurfural content, diastase number  of caramelized honey have been investigated. The difference between the sizes of nanoparticles of raw and caramelized honey has been revealed, namely caramelized honey (1.5-2.0 times) of smaller size encourages their biochemical activity. On the basis of the results obtained from caramelized honey, wax and beeglue as well as their properties, the chewing gum with biologically active components for the prevention and treatment of periodontal tissue diseases (gingivitis, periodontitis and periodontal disease) was invented. Clinical studies on chewing gum with honey, wax, and beeglue have confirmed that it provides health benefits among 72 % of patients.

Emerita brasiliensis is an important species of Brazilian macrofauna, they are inhabitants of the intertidal areas, and have important components that enable their use as biological indicators environmental. Therefore, the objective was to analyze the relationship between population and size of individuals of Eremita brasiliensis, comparing two beaches on the coast of Santa Catarina, being Praia brava in Itajaí, with an increasing level of urbanization and Guarda do Embaú Beach in Paulo Lopes, which has a stationary degree. The collections took place in March and September 2016, with the sample area parallel to the sand and intertidal strips for a systematic sampling observing the estimated time for low tide. For collection, a 20cm diameter PVC cylinder was used and buried at a depth of 20cm. The samples were arranged in a 0.5mm opening mesh and sent to the laboratory, where the organisms of the genus Emerita brasiliensis were separated and identified for the measurement of biomorphometric data, observing the lateral diameter and rostro-caudal length of the carapace. The biomass weighing was performed before and after the drying procedure, performed in a controlled temperature oven at 37ºC for 48 hours. For statistical analysis, the ANOVA test was used. Based on the individuals collected, it is observed Guarda do Embaú beach with more individuals when compared to Brava Beach. Statistical data show a significant difference between the months and the beaches, which is justified by the state of conservation of Guarda do Embaú beach, which remains static due to its low urbanization. Therefore, it is concluded that the difference between Emerita Brasiliensis communities is due to changes in local dynamics, such as anthropic trampling and sediment change. The results were not accurate due to the low number of samples, but are significant and relevant for further research.
