Abstract
Background and Aim: Dental injuries are one of the common problems in children. Considering that nowadays, more attention is being paid to dental health and that school health teachers play a key role in the management of dental injuries, this research was designed with the aim of determining the extent of the knowledge of elementary school health teachers of Tehran city on how to control students’ teeth injuries at school.
Materials and Methods: This research is a cross-sectional study. The questionnaires were given to 280 elementary school health teachers in Tehran city. Of the 280 questionnaires, 216 were answered (77.14%). Data were collected and statistical analysis was performed using descriptive statistics methods and inferential statistics test in two study populations, chi-square independence and Spearman correlation coefficient with 95% confidence interval (CI).
Results: Receiving medical emergency training courses affected the responses to the questions regarding the maximum time to restore the teeth to their location (p = 0.001), and the most appropriate action in case of altered consciousness (p = 0.05). Receiving dental emergency training courses had no impact on the responses to any of the other questions (p = 0.231). According to Spearman correlation test results, there was a weak reverse significant correlation between age and the question regarding the most appropriate way to reposition the teeth in this case (p = 0.031 and correlation coefficient = - 0.157), and between work experience and the question regarding distinguishing the tooth type (p = 0.042 and correlation coefficient = - 0. 153).
Conclusion: the results indicated that the knowledge of these teachers is not adequate, and that there is a need for education regarding the management of dental injuries. Furthermore, there is no significant correlation between the responses to the questionnaire and receiving dental emergency training courses.
Keywords: Knowledge of health teachers, Elementary school, Dental injuries, Control dental injuries
Introduction
Knowledge of the complications caused by dental injuries plays an important role in controlling the outcomes; however, according to various studies, it seems that the knowledge of teachers in this regard is not adequate. For example, in a study by Caglar et al, knowledge regarding the type of storage medium for avulsed teeth was 17.9% (1). Another study in Hong Kong showed that when there is a need for replanting the teeth, only 5.4% of the teachers perform the replantation (2). In a study conducted in Iran, teachers' knowledge of dealing with dental injuries, particularly avulsed teeth, was 15.1% (3). Even the teachers have noticed this low percentage. In a study conducted in Singapore, 79% of the teachers were concerned with this issue (4). Dental injuries are one of the common problems in children, which impose a serious danger that potentially threats every child and can cause a lot of pain and discomfort (5). These injuries encompass damages to the teeth and the surrounding gingivae, and include subluxated, laterally luxated, and avulsed teeth, and crown and root fractures. Most dental accidents happen at the ages of 8 to 11 years. As a result, knowing how to manage dental injuries is very important in achieving treatment success (1). Studies in Scandinavia have shown that 22-30% of school children have experienced dental trauma to the permanent and deciduous teeth. It has also been estimated that over 50% of children are susceptible to dental injuries. Dental trauma may increase dental caries and periodontal diseases, and these two are considered as serious threats to dental health in childhood and adolescence with economic implications as well (2). Meanwhile, timely replacement of avulsed teeth or keeping them in proper condition will result in preservation of damaged teeth. Considering that nowadays, more attention is being paid to dental health and that school health teachers have a key role in the management of dental trauma, this study was designed with the aim of determining the extent of the knowledge of elementary school health teachers of Tehran city on how to control teeth injuries at school in 2014.
Materials and Methods
This research is a cross-sectional study. After translation and re-translation for validity check (4), the questionnaire was approved by three endodontists. The questionnaire consisted of 7 items:
1- Case 1 question 1 (Distinguishing the tooth type: Deciduous or permanent, based on the age of the patient in the questionnaire).
2- Case 1 question 2 (The most appropriate action in this case).
3- Case 2 question 1 (the most appropriate action in case of avulsion).
4- Case 2 question 2 (Maximum time to restore the teeth to their location).
5- Case 2 question 3 (Best environment to keep the avulsed tooth).
6- Case 3 question 1 (The most appropriate action in case of altered consciousness).
7- Case 3 question 2 (The most appropriate way to reposition the teeth in this case).
The reliability of the questionnaire was determined by test-retest method in a time interval of two weeks, based on the responses of 20 school health teachers, and no significant differences were found (p = 0.36). After this stage, the questionnaires were given to 280 elementary school health teachers of Tehran city in northern, southern, western and eastern regions selected by census in 2014. Of the 280 questionnaires, 216 were answered. After collecting the questionnaires, the data were analyzed to obtain the mean level of knowledge among the study population using descriptive statistics methods (frequency tables, graphs, and data calculation) and inferential statistics test in two study populations, chi-square independence and Spearman correlation coefficient with calculation of 95% confidence interval (CI).
Results
The study was conducted on 216 female subjects who had answered the questionnaires. The tables were drawn based on data analysis. According to the results achieved from χ2 independence test, receiving medical emergency training courses affected the responses to case 2 question 2 (Maximum time to restore the teeth to their location) (p =0.001) and case 3 question 1 (the most appropriate action in case of altered consciousness) (p =0.05). Accordingly, subjects who had received medical emergency training courses gave wrong answers to case 2 question 2 (74.3%), and correct answers to case 3 question 1 (90.7%). In the other cases, receiving the mentioned courses did not have any effect on the answers to the questions (p=0.304). Also, receiving dental emergency training courses did not have any effect on the responses to all questions (p =0.231).
According to Spearman correlation test results regarding the variable of age and relevant questions in the questionnaire, there was a weak reverse significant correlation between age and the responses to case 3 question 2 (the most appropriate way to reposition the teeth in this case) (p = 0.031 and correlation coefficient = - 0.157), which means that older people often provided the wrong answer to this question.
Table 1: Response percentage in teachers who had passed medical or dental emergency training courses
Based on Spearman correlation test results regarding the variable of work experience and relevant questions in the questionnaire, there was a weak reverse significant correlation between work experience and the responses to question 1 from case 1 (distinguishing the tooth type) (p = 0.042 and correlation coefficient = - 0. 153), which means that people with more work experience often had the wrong answer for this question.
Table 2: Evaluation of the most chosen options in responding to the questions
According to Table 2, in case 1 question 1 (Distinguishing the tooth type), case 2 question 2 (Maximum time to restore the teeth to their location), case 2 question 3 (Best environment to keep the avulsed tooth), case 3 question 1 (The most appropriate action in case of altered consciousness), and case 3 question 2 (The most appropriate way to reposition the teeth in this case), the most chosen option is also the correct answer. According to the survey, 94% of the teachers felt the need for dental trauma training. Moreover, the percentage of the subjects who had received dental or medical emergency training courses was 12% and 56.9%, respectively. The extent of the knowledge was 54.15% on average with 35.65% wrong answers on average.
To evaluate the test-retest reliability, the questionnaires were given to 20 teachers in two 10-day periods, and no significant differences were detected among the given answers (p=0.36).
Discussion
Dental injuries are one of the common problems in children that cause severe pain and discomfort (5). Knowing how to manage these injuries is critical for successful treatment (1). Since health teachers play a key role in the management of dental injuries at schools, assessing their knowledge will have a great impact on preventing the complications caused by these injuries. This study was conducted on 280 primary school health teachers of Tehran city, where 216 of them participated and therefore, the response rate equaled 77.14%, which is a significant percentage. Data analysis showed that there was no significant correlation between receiving dental emergency training and the extent of the teachers' knowledge. This could indicate that either these courses are not beneficial or the learners have not memorized them. However, in subjects who had received medical emergency training, there was a significant correlation between the responses to the question regarding the maximum time to restore the teeth to their location and the question regarding the most appropriate action in case of altered consciousness. A greater percentage (74.3%) gave wrong answer to the question regarding the maximum time to restore the teeth to their location, which either means insufficient information rendition during medical emergency training or provision of false information in this respect.
Pithon et al. performed a study on the elementary school teachers' knowledge of dental trauma management (6). They found that nearly half of the teachers have satisfactory knowledge in this regard, and that women have higher knowledge than men. Moreover, being older, having more knowledge and experience, being experienced in such incidents or receiving first aid training courses had no effect on increasing the awareness. In the present study, there was no significant correlation between the teachers' knowledge and above-mentioned factors. However, a weak reverse correlation was detected, probably due to the fact that younger subjects with less work experience are more educated and thus have higher knowledge in this respect. Caglar et al. conducted a study in 2005 in two southern European cities to review the teachers' knowledge of dental trauma management (1). They concluded that more correct answers (66%) were provided by Porto teachers regarding the proper storage medium for avulsed teeth, which is similar to the results of the present study (48% correct answers). Moreover, a large percentage of the participants of the mentioned study gave correct answers to the question regarding the maximum time that the avulsed tooth can stay out. However, our research indicated a low ratio of 33% correct answers that shows lack of knowledge among the teachers. Finally, this study also considered improving the teachers’ knowledge when necessary.
Singh et al. conducted a research where teachers with higher education level or with higher physical education level provided more correct answers regarding the storage media for avulsed teeth and the duration that these teeth can stay out. (7) However, in the present study, we found no such significant correlation. In a study by Chan et al. which was conducted in Hong Kong in 2001, despite the large number of subjects who had participated in first aid training, the knowledge of dental trauma management was inadequate. (2) For example, the knowledge regarding the best material for preserving, cleaning and transferring the avulsed tooth was only 9%, and the most chosen option was ice. The authors believed that this answer was relevant to using ice in transferring and preserving body organs. However, in the present study, 48% of the participants chose milk. Moreover, in the mentioned article, no significant correlation was found between the knowledge and age of the participants, which is similar to the results of the current study (except for question 2 from case 3, where there was a reverse significant correlation). Another survey was conducted in the mentioned study on the detection of deciduous or permanent teeth of 8-year-old children, where the majority of the subjects (47%) answered the questions correctly. Similarly, a high percentage of the teachers in our study gave correct answers to the corresponding questions (71.8%).
Fallahinejad et al. conducted a study in Tehran on this subject (3). The results showed no correlation between receiving first aid training and knowledge of dental trauma management, which is similar to the findings of the present study. In the above-mentioned study, 15.5% of the subjects were aware of tooth avulsion management, 42.7% were familiar with crown fracture, and 68.5% were familiar with complete crown loss. The level of knowledge regarding avulsed teeth was approximately consistent with that in our study (30.1%). However, in the cited study, a significant correlation was found between the teachers' knowledge and history of trauma in children (p<0.01), which was different from the results of the present study.
Al-Jundi et al. investigated the knowledge of teachers in the management of dental trauma (5). Similar to the present study, the results showed no significant correlation between age, work experience, receiving first aid training and the responses. In the same study, the response percentage and level of cooperation were high (86.3%). Notably, in comparison to our study (71%), fewer subjects responded to the question regarding determination of the tooth type (only 40.3%). Sae-Lim and Lim conducted a comparable study on preschool teachers in Singapore (4). Similar to our study, 95% of the subjects felt the need for dental emergency training (94% in our study). In the cited study, a very small percentage of the subjects (15%) were aware of the type of suitable storage media, which was not consistent with the findings of our study (48.1%). Regarding the knowledge about permanent teeth replantation, subjects who had more work experience provided better answers (p=0.003). Meanwhile, the present research did not find such significant correlation.
Conclusion
According to the results of the present research, it seems that the knowledge of the assessed teachers is not adequate, and that there is a need for education regarding the management of dental injuries. Furthermore, there is no significant correlation between the responses to the questionnaire and receiving dental emergency training courses.
