Background and Aims: Human ergonomics or engineering with proper design and change of work and requirements creates the most productivity based on human physiology. The purpose of this study was to determine the level of awareness of dental students of Isfahan University of Medical Sciences about the basic principles of ergonomics in dentistry.
Materials and Methods: In this descriptive-analytical, sectional study, a questionnaire containing 10 questions was distributed and completed by easy sampling method among 74 final year students of the general doctorate of Isfahan school of dentistry. After collecting the questionnaires, the students were given an educational pamphlet. To evaluate the questionnaires, each correct answer was given a score of one and the wrong answers were given a score of zero. Data were analyzed by T-test, Kai Square, and Mann-Whitney statistical tests using SPSS23 software. P<0.05 was considered as a significant level. P<0.05 was considered as a significant level.
Results: The average score of the knowledge of principles of ergonomics was intermediate (6.23±1.25). Student knowledge was not significantly different based on the student gender (P=0.25) and academic semester (P=0.059). Also, 55% of students had a history of muscle pain that did not have a significant relationship with gender (P=0.258) and average score of the knowledge (P=0.288).
Conclusion: Unfortunately, ergonomics cannot be considered part of the principles of dental education and even later. Musculoskeletal pain is one of the most common complaints of dentists and is a factor in reducing their quality and function. Therefore, it seems that training and evaluation of ergonomic principles in dental education is necessary.

Background and Aims: The increase in life expectancy and decrease in birth rate enhances the elderly population in different societies and consequently, the demand from the health system for providing the treatment needs has been elevated. It has been proposed that dentists must improve their attitude, knowledge, and practice to meet these needs. The present study aimed to assess the knowledge, attitude, and practice of general dentists regarding geriatric oral health.
Materials and Methods: In this descriptive-analytic cross-sectional study, 150 general dentists participating in the annual congress of the Iranian Dental Association in 2018 were selected and completed a valid and reliable self-administered questionnaire including 5 parts about knowledge, attitude and practice regarding old age and oral health of elders. SPSS23 and multiple regression were used for data analysis.
Results: The mean age of dentists was 34.3 (SD: 9.1) and 92 (61.3%) of participants were women. The mean knowledge score about the old age was 16.67 (of maximum: 26, SD: 4.31) and the mean knowledge on the geriatric oral health was 11.01 (of maximum: 18, SD: 2.81). The mean general attitude about elderly was 19.1 (of maximum: 30, SD: 4.26), the mean attitude on geriatric oral health was 13.09 (of maximum: 20, SD: 2.65), and the mean practice about geriatric oral health was 6.5 (of maximum: 10, SD:2.96). Age was significantly associated with knowledge regarding the elderly (P<0.034); i.e. with increase in age lower scores in knowledge were gained.
Conclusion: General dentists participating in the congress of the Iranian Dental Association demonstrated a medium level of knowledge, attitude, and practice regarding the oral health of elders. Proper educational programs should be planned in dental schools to improve dental student's knowledge, attitude and practice about geriatric oral health.

Background and Aims: School teachers have key role in providing the basic health information for their students, and their knowledge, attitude, and practice affect children's oral health through developing of the healthy behaviors. The goal of this study was to evaluate the effectiveness of an oral health education program for primary school teachers on their knowledge, attitude, and practice fields in the framework of oral health promoting schools.
Materials and Methods: This quasi-experimental pre-post study was conducted among five oral health promoting schools in Isfahan city in 2019. A validated and reliable questionnaire including four sections of demographic data, knowledge, attitude, and practice was applied for data collection. The questionnaire contained 24 knowledge, 9 attitudes, and 5 practice questions. It was distributed among 63 enrolled teachers at base line and two months later after two educational-emotional workshops. Before and after data were analyzed by SPSS21 (α=0.05) by related samples Wilcoxon signed rank test and background variables by Kruskall-wallis test.
Results: After the educational intervention, their knowledge score increased significantly from 14.1±3.8 to 18.5±3.7 (P<0.001). About 34% of teachers had a high level of knowledge proficiency at the beginning of the study which eventually rose to 76%. Teachers’ attitude decreased significantly from 34.6±5 to 31.4±4.6 (P<0.001). At the beginning of the study, 89% of them had a positive attitude towards oral health programs which decreased to 84% at the end of the study. In the performance part, 63.5% of the teachers paid attention to the fluoride in their toothpaste which reached 87.3% after the workshop and the teachers' performance score increased from 3.07 to 3.39 after the intervention (P<0.012).
Conclusion: The package of educational intervention for teachers in oral health-promoting schools improved the level of knowledge and practice, but slightly reduced the level of attitude. However, due to the importance of changing attitudes in teachers and the existence of structural and programmatic barriers to integrate the health issues into school education, other models need to be evaluated and compared.
