  • a survey on hong kong secondary school students knowledge of emergency management of Dental Trauma
    PLOS ONE, 2014
    Co-Authors: Cecilia Young, Kin Yau Wong, L K Cheung
    Abstract:

    Objectives To investigate Hong Kong secondary school students' knowledge of emergency management of Dental Trauma. Method A questionnaire survey on randomly selected secondary school students using cluster sampling. Results Only 36.6% (209/571) of the respondents were able to correctly identify the appropriate place for treatment of Dental injury. 55.2% of the respondents knew the suitable time for treatment. Only 24.7% of the respondents possessed the knowledge of how to correctly manage fractured teeth. Only 23.6% of them knew how to manage displaced teeth. 62.5% of them correctly answered that knocked-out deciduous teeth should not be replanted to the original position, but few of them (23.6%) knew that permanent teeth should be replanted. Moreover, 37.1% of the respondents correctly identified at least one of the appropriate media for storing a knocked-out tooth. First-aid training and acquisition of Dental injury information from other sources were significant factors that positive responses from these questions would lead to higher scores. Conclusion Hong Kong secondary school students' knowledge of emergency management of Dental Trauma is considered insufficient. An educational campaign in secondary schools dedicated to students is recommended. Prior first-aid training and acquisition of Dental injury information from other sources positively relate to the level of knowledge. Dental Trauma emergency management is recommended to be added to first-aid publications and be taught to students and health professionals.Trial Registration: Hong Kong Clinical Trial Centre HKCTR-1344

  • effectiveness of educational poster on knowledge of emergency management of Dental Trauma part 1 cluster randomised controlled trial for primary and secondary school teachers
    PLOS ONE, 2013
    Co-Authors: Cecilia Young, Kin Yau Wong, L K Cheung
    Abstract:

    Objective: To investigate the effectiveness of educational posters in improving the knowledge level of primary and secondary school teachers regarding emergency management of Dental Trauma. Methods: A cluster randomised controlled trial was conducted. 32 schools with a total of 515 teachers were randomised into intervention (poster) and control groups at the school level. Teachers’ baseline levels of knowledge about Dental Trauma were obtained by using a questionnaire. Posters containing information on Dental Trauma management were displayed in the school medical room, the common room used by staff, and on a notice board for 2 weeks in each school of the intervention group; in the control group, no posters were displayed. Teachers in both groups completed the questionnaire after 2 weeks. Results: The teachers in the intervention schools (where posters were displayed for 2 weeks) showed statistically significant improvement in scores in cases where they had not previously learned about Dental emergencies from sources other than first aid training, with an average score increase of 2.6656 (score range of questionnaire, 213 to 9; p-value ,0.0001). Conclusion: Educational posters on the management of Dental Trauma can significantly improve the level of knowledge of primary and secondary school teachers in Hong Kong.

  • emergency management of Dental Trauma knowledge of hong kong primary and secondary school teachers
    Hong Kong Medical Journal, 2012
    Co-Authors: Cecilia Young, Kin Yau Wong, L K Cheung
    Abstract:

    OBJECTIVES. To investigate the level of knowledge about emergency management of Dental Trauma among Hong Kong primary and secondary school teachers. DESIGN. Questionnaire survey. SETTING. A teachers' union that unites 90% of teachers in Hong Kong. PARTICIPANTS. Randomly selected primary and secondary school teachers. RESULTS. Only 32.8% of respondents correctly stated that a person sustaining Dental Trauma should go to dentists directly. In all, 73.1% of teachers correctly stated that a Dental Trauma patient should go for treatment immediately. Only 32.5% knew that a fractured tooth should be put in liquid. Even fewer (23.2%) realised that the displaced tooth should be repositioned back to the original position. Relatively more respondents (74.7%) understood that an avulsed baby tooth should not be put back. Disappointingly, only 16.3% of teachers knew that an avulsed permanent tooth should be replanted. Furthermore, only 29.6% of teachers thought that they were able to distinguish between deciduous teeth and permanent teeth, whilst 20.4% correctly identified at least one of the appropriate mediums: milk, physiological saline or saliva, for storing an avulsed tooth. Teachers who previously received first-aid training with Dental content or acquired Dental injury information from other sources, scored significantly higher than teachers without such training or acquired information. CONCLUSION. The knowledge on emergency management of Dental Trauma among primary and secondary school teachers in Hong Kong is insufficient, particularly on the handling of permanent tooth avulsion and the appropriate storage medium for avulsed teeth. Receipt of first-aid training with Dental contents and acquisition of Dental injury information from other sources were positively correlated with knowledge in managing Dental Trauma.

  • Dental Trauma prevalence and risk factors in schoolchildren
    Community Dentistry and Oral Epidemiology, 2014
    Co-Authors: Marilia Leao Goettems, Dione Dias Torriani, Pedro C Hallal, Marcos Britto Correa, Flavio Fernando Demarco
    Abstract:

    OBJECTIVES: This cross-sectional study aimed to determine the prevalence of Traumatic injury to the permanent incisors in 8- to 12-year-old children and to test associations between Dental Trauma and nutritional status and physical activity level, with adjustment for demographic, behavioral, and psychosocial variables. Differences in risk factors between sexes were also assessed. METHODS: Two-stage cluster sampling was used to select 1210 children in 20 public and private schools in Pelotas, Brazil, for study participation. Dental Trauma was assessed using the O'Brien criteria. Parents provided information about socioeconomic characteristics and their children's history of Trauma in early childhood via questionnaire. Children were interviewed to obtain demographic and psychosocial information and to assess physical activity level. Anthropometric measures were collected for body mass index calculation. Hierarchical Poisson regression was used for data analyses. RESULTS: The prevalence of Dental Trauma was 12.6% [95% confidence interval (CI), 10.8-14.7%] in the entire sample; it increased with age from 7.2% at 8 years to 21.5% at 12 years. In the adjusted analysis, Dental Trauma was more prevalent in boys [prevalence ratio (PR) = 0.71; 95% CI, 0.50-0.99], older children (PR = 3.57; 95% CI, 1.73-7.34), those with inadequate lip coverage (PR = 2.03; 95% CI, 1.22-3.38), and those with histories of Trauma in the primary dentition (PR = 2.60; 95% CI, 1.80-3.75). In a sex-stratified analysis, Dental Trauma was more prevalent in overweight/obese boys (PR = 1.65; 95% CI, 1.10-2.92). No significant association was found with socioeconomic variables, psychosocial characteristics, physical activity level, or school retention among boys or girls. CONCLUSIONS: The pronounced increase in the prevalence of Dental Trauma with age highlights the need to establish preventive strategies among schoolchildren. The risk of Dental injury was increased in overweight/obese boys and children with histories of Dental Trauma in early childhood, confirming the existence of accident-prone children. Language: en

  • Dental Trauma occurrence and occlusal characteristics in brazilian preschool children

    Co-Authors: Marilia Leao Goettems, Marcos Britto Correa, Marina Sousa Azevedo, Catiara Terra Da Costa, Flavia Priescht Wendt, Helena Silveira Schuch, Maria Laura Menezes Bonow, Ana Regina Romano, Dione Dias Torriani
    Abstract:

    PURPOSE: The purpose of this study was to analyze the association between Dental Trauma and occlusal traits in the primary dentition. METHODS: Five hundred and one 24- to 71-month-old children, attending both private and public schools in Pelotas, Rio Grande do Sul, Brazil, were included. Clinical examinations were performed at each school. Occurrence of Dental Trauma was assessed using the Andreasen and Andreasen classification. Occlusal characteristics used in this study were: overjet; open bite; overbite; anterior crossbite; crowding and rotated teeth occurrence; and canine class. The occlusion type was classified according to the World Health Organization. A questionnaire was sent to parents to obtain socioeconomic data. Descriptive statistics were used, as well as chi-square tests (for heterogeneity or linear trend; P ≤ .05) and Fisher's exact test. RESULTS: The prevalence of Dental Trauma was 40% (95% confidence interval=35-44). Of all children examined, 20% showed normal occlusion, 42% mild malocclusion, and 38% moderate/severe malocclusion. Dental Trauma was associated with overjet ≥ 3 mm (P=.02), overbite ≥ 3 mm (P=.01), and canine class (P=.04). Children bearing mild or moderate/severe malocclusion presented greater Dental Trauma (P<.01). CONCLUSION: The findings of this study emphasize the importance of preventing Dental Trauma, especially in children presenting increased overjet, overbite, or canine Class II.

  • survey on the occurrence of Dental Trauma and preventive strategies among brazilian professional soccer players
    Journal of Applied Oral Science, 2010
    Co-Authors: Marcos Britto Correa, Dione Dias Torriani, Pedro C Hallal, Helena Silveira Schuch, Kaue Collares, Flavio Fernando Demarco
    Abstract:

    OBJECTIVES: The aims of this study were to verify the occurrence of Dental injuries in professional Brazilian soccer players, the level of knowledge of the teams' medical departments about mouthguards, and the conducts adopted in cases of Dental Trauma during the match. MATERIAL AND METHODS: Closed questionnaires were sent to the physicians in charge of the medical departments of the 40 teams enrolled in the first and second divisions of the Brazilian professional soccer league in 2007. The data obtained were subjected to descriptive analysis to determine absolute and relative frequencies of answers for each one of the questions. RESULTS: Physicians from 38 (95%) of the 40 teams in the first and second divisions answered the questionnaires and 71.1% reported the occurrence of some type of Dental injury during soccer practice, Dental fractures (74.1%) and avulsions (59.3%) being the most prevalent ones. Regarding emergency conducts, approximately 50% answered that a successful replantation could be obtained in periods from 6 to 24 h after injury, and 27.8% were not able to answer this question. Regarding mouthguard use, 48.6% of the physicians did not know about mouthguards, and only 21.6% usually recommended their use by the soccer players. Among the physicians who do not recommend the use of mouthguards, 50% justified that it was not necessary. Almost 50% of the medical departments do not have a dentist as part of the health professional staff. CONCLUSIONS: It was possible to conclude that Dental injuries are common during professional soccer practice and that there is a lack of information in the medical departments related to the emergency conducts and prevention of Dental Trauma.
