A comparison of dentist-led, teacher-led, peer-led and self-learning strategies for educating school children aged 10-13 years about prevention of oral diseases including tooth decay, gum disease and oral cancer

Introduction and Objective: Tooth decay is one of the most common chronic oral diseases found in industrial countries and is a multifactorial disease which has sugar as a key dietary factor. The amount of saliva concentration and presence of cariogenic bacteria will favor the development of caries. Because of this, the aim of this study was to collect and analyze data on oral alterations referred to tooth decay, oral pH changes, and changes of the oral microbiota in two distinct groups of workers. Material and methods: 30 individuals belonging to two different groups of workers: group A (GA) – workers who maintain daily contact with the confectionery; group B (GB) – workers who do not have such contact. Saliva collection was done by analysis of the salivary pH in both groups, as well as cultivation of Lactobacillus spp and S. mutans. We also evaluate the dental status of individuals belonging to the two groups through the DMFT index. Results: After the examinations of 30 workers (17 from the GA [9 men and 8 women] and 13 in the GB [7 men and 6 women]), the mean DMFT of the individuals in the group A and group B, was 7.41 (SD 5.14) 7.08 (SD 5.56), respectively, without statistically significant differences (p < 0.05). The count of S. mutans and Lactobacillus spp, was not statistically significant. Conclusion: There was no statistically significant relationship between presence of dental caries and the fact that workers are in contact with sugar because they work on candy food industry, but new studies are needed for more precise research.

The purpose is to minimize color overflow and color patch generation in intelligent images and promote the application of the Internet of Things (IoT) intelligent image-positioning studio classroom in English teaching. Here, the Convolutional Neural Network (CNN) algorithm is introduced to extract and classify features for intelligent images. Then, the extracted features can position images in real-time. Afterward, the performance of the CNN algorithm is verified through training. Subsequently, two classes in senior high school are selected for experiments, and the influences of IoT intelligent image-positioning studio classroom on students’ performance in the experimental class and control class are analyzed and compared. The results show that the introduction of the CNN algorithm can optimize the intelligent image, accelerate the image classification, reduce color overflow, brighten edge color, and reduce color patches, facilitating intelligent image editing and dissemination. The feasibility analysis proves the effectiveness of the IoT intelligent image-positioning studio classroom, which is in line with students’ language learning rules and interests and can involve students in classroom activities and encourage self-learning. Meanwhile, interaction and cooperation can help students master learning strategies efficiently. The experimental class taught with the IoT intelligent positioning studio has made significant progress in academic performance, especially, in the post-test. In short, the CNN algorithm can promote IoT technologies and is feasible in English teaching.

Abstract Background Dental health is often neglected by the majority of the population and has contributed to the global burden of oral diseases. We assessed awareness, utilization and barriers to seeking oral health care among adults in Nebbi District, Uganda. Methods A community-based, cross sectional study was conducted in the central division, Nebbi District in Uganda among adults between the age of 18 years or older. An interviewer-administered, semi-structured questionnaire was used for data collection on socio-demographic characteristics, oral health awareness, oral health utilization, associated factors and barriers. Results A total of 400 adults with a median age of 32 years (interquartile range 24–43) years were enrolled. More than half (57.5%, n = 230) of the participants were female. Participants identified smoking (42.8%, n = 171) and consumption of sugary foodstuffs (29.0%, n = 116) as risk factors for oral disease. Not brushing was also identified by 260 participants (65.0%) as the cause of tooth decay and 95.8% (n = 383) believed brushing one’s teeth could prevent tooth decay. Of the 51.5% (n = 206) who had experienced a toothache or discomfort 12 months prior to the study but only about half (52%, n = 106) had sought healthcare from a dental clinic or facility. About 89.5% (n = 94) of the participants were able to see a dentist during their last visits. Dental carries (76.6%, n = 70) and gum bleeding (14.9%, n = 14) were the most frequent reasons for visiting a dental clinic, and 73.7% (n = 70) had their tooth extracted. Barriers to seeking oral healthcare were cost of treatment (47.5%, n = 190), and long waiting time (18.5%, n = 74). The odds of seeking oral healthcare was 2.8-fold higher in participants who were being married (Odds ratio (OR): 2.8, 95% CI 1.3–6.3, p = 0.011) and 3.5-fold higher among housewives (COR: 3.5, 95% CI 1.1–11.4, p = 0.040). Conclusion About half of the participants had sought healthcare following a dental condition. Cost of treatment seems to be an important factor affecting utilization of oral health services. Optimization of costs, and creating awareness regarding benefits of utilizing preventive dental services are recommended.

Abstract The older population in the United States is growing at an unprecedented rate. Oral diseases such as oral cancer can affect physical, psychological, and social well-being in older adults. Oral cancer screening can prevent development of the disease in high-risk individuals. The purpose of this research was to assess determinants of preventive oral health behavior including oral cancer screening in noninstitutionalized older adults living in rural/medically underserved communities of southeast Georgia. A mixed methods sequential explanatory design was used. Surveys were administered to 206 individuals aged 50 and older. Phone interviews were conducted with 22 individuals from the survey sample and 11 key informants. The majority of the participants (83.01%) said they had never been examined for oral cancer by a doctor or a dentist. Those who correctly recognized the most common sign of oral cancer were about three times more likely (OR=3.75; 95% CI: 1.04 – 13.50) to have had an exam for oral cancer (p=0.04). The survey participants who lived alone were more likely (OR = 4.39; 95% CI = 0.95 – 20.26) to have been examined for oral cancer (p = 0.05). During the interview, older adult participants rarely mentioned oral cancer with regards to an unhealthy mouth. The interview participants revealed that living alone gave them more time to pay attention to their health. For the older adults, prevention of oral diseases was grounded in the autonomy in their own behaviors, while the key informants saw more macro community and systems- level factors as the solution.

Hygiene Practices

Inadequate oral health knowledge and awareness is more likely to cause oral diseases among all age groups, including children. Reports about the oral health awareness and oral hygiene practices of children in Bangladesh are insufficient. Therefore, the objective of this study was to evaluate the oral health awareness and practices of junior school children in Mathbaria upazila of Pirojpur District, Bangladesh. The study covered 150 children aged 5 to 12 years of age from three primary schools. The study reveals that the students have limited awareness about oral health and poor knowledge of oral hygiene habits. Oral health awareness and hygiene practices amongst the school going children was found to be very poor and create a much-needed niche for implementing school-based oral health awareness and education projects/programs.

Abstract Background: Oral diseases are common and widespread around the world. The most common oral diseases are preventable and early onset is reversible. Myanmar faces many challenges in rendering oral health services because about 70 percent of the total population resides in rural areas. These relate to the availability and accessibility of oral health services. Therefore, oral health education is one key element to prevent oral diseases and to promote oral health.Methods: A quasi-experimental study was carried out at Basic Education Middle Schools in rural areas of Magway Township to study the effectiveness of oral health education on knowledge and behavior of eight to ten-year-old school children. A total of 220 school children, 110 from the intervention school, and 110 from the control school participated in this study from 2015 to 2017. Data were collected before and after intervention in the two groups by using a self-administered questionnaire. Tooth brushing method data were collected by direct observation with a checklist. Oral health education was provided at eight weekly intervals for one year. At one and a half years, third-time data collection was done on the intervention group to assess retention. Chi-square test, two samples t-test, one way repeated measure ANOVA were used for data analysis. The study was approved by the Institutional Review Board at the University of Public Health,Yangon, Myanmar.Results: There were significant differences between the two groups in oral health knowledge (p<0.05) except one and also in behavior (p<0.001) after the intervention. A positive effect of the intervention was found in the intervention group. The intervention had a significant effect on the sustainability of the correct knowledge and behavior of the intervention group although the education session was stopped for six months (p<0.001). Their mean knowledge and behavioral scores at three different points got at these times were (2.45±1.12 and1.56±0.90) at baseline, (3.79±1.12 and 3.60±1.21) at one year after education, and (4.07±0.98 and 3.24±1.31) at six months after cessation of education, respectively. Conclusions: The repeated oral health education was effective to promote and sustain oral health knowledge and behavior.
