Introduction:Dental injuries could happen anywhere, including in the school compound. Correct management by the teachers in dental emergencies could prevent further damage to the traumatized tooth and improve the success rate of the treatment. Hence, the purpose of this study was to assess the knowledge and attitude towards dental trauma management among the primary school teachers in Kubang Kerian area. Methods: This descriptive study was conducted in three national primary schools in Kubang Kerian and multi-stages sampling was performed to select the subjects. One hundred and twenty teachers (n = 120) were randomly selected and responded to a set of a self-administered questionnaire. The questionnaire consisted of general characteristics, knowledge, and attitude towards dental trauma. Results: A total of 120 primary school teachers, predominantly female teachers (74.2%) participated in this study. More than half of the teachers (62.5%) have more than 15 years of teaching experience. Onethird of the teachers (34.2%) have completed first aid training; however, dental trauma management subject was lacking (1.7%). About 31.7% of the respondent had experienced dental trauma case. Eightyfive percent of the teachers did not opt for tooth replantation in the case of avulsion and almost all the teachers (97.5%) did not choose fresh milk as the medium storage of the avulsed tooth. Conclusion: The level of knowledge and attitude on dental trauma management among school teachers is unsatisfactory. As a recommendation, first aid training given to the teachers should include basic knowledge of dental trauma management. The awareness can be improved by organizing talk or campaign on dental trauma management at the school level.
This systematic review aimed to identify the intercanine and intermolar width changes following palatal expansion in bilateral posterior crossbite (PXB) in mixed dentition. This review was registered in the PROSPERO database (CRD42021275833). All randomized controlled trials (RCT) and non-RCT articles between 1980 and August 2022 on the palatal expansion of bilateral PXB in mixed dentition were searched in seven online databases (Google Scholar, Ovid, Web of Science, Scopus, EBSCOHost, Cochrane Library and PubMed). The risk of bias (RoB) of the articles included was analyzed using the Joanna Briggs Institute (JBI) critical appraisal tool. Three non-RCT studies were included and showed a low risk of bias. Meta-analysis on the changes in intercanine and intermolar widths was not performed due to study design heterogeneity. One study reported an over-correction of the bilateral PXB. There is a need for more RCT studies with standardized landmark measurements, outcome assessment methods and retention periods to investigate the interdental changes following palatal expansion.
Introduction. Hall’s technique preformed metal crown (HTPMC) has been used widely by pediatric dentists in developed countries as a new approach for managing decayed primary molars without local anesthesia, caries removal, and tooth preparation. Currently, inadequate information is available regarding the implementation of this technique (HTPMC) in Malaysia. This study is aimed at evaluating the implementation of HTPMC by Malaysia’s pediatric dentists and identify the co-occurrence frequencies of the HTPMC implementation with the respondents’ demographic profile. Materials and Methods. A cross-sectional questionnaire-based research was conducted among 65 pediatric dentists in Malaysia. Online questionnaires were distributed to the pediatric dentists employed at public hospitals (MOH) and universities in Malaysia. Result. It was found that over half of the respondents (65.6%) employed HTPMC. The analysis of the co-occurrence network frequency revealed that a high frequency of female pediatric dentists who were within the age group of 31-40 years old had fulfilled their postgraduation overseas and was employed in the university mainly applied HTPMC. Conclusion. The application of HTPMC among respondent pediatric dentists in Malaysia was high. However, most respondents considered HTPMC a treatment option only to manage carious primary molar rather than a treatment of choice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
