Initial testing of OHLI suggested that it is a valid and reliable instrument to evaluate oral health literacy among adults, although additional work is needed to investigate the instrument's predictive validity and sensitivity to change using oral health outcomes with population groups known to be at high risk of low functional oral health literacy.
Objectives:To assess the incidence and awareness of taekwondo athletes in Saudi Arabia regarding oral and maxillofacial (OMF) injuries and their prevention.Methods:In this cross-sectional study, an online questionnaire about the incidence and awareness of OMF injuries and their prevention was developed and distributed to taekwondo athletes in Saudi Arabia via their coaches.Results:Sixty-eight responses were collected. The mean age of the participants was 29.3±9.1 years and 97% of them were males. Most of the participants (83%) believed that they are vulnerable to OMF injuries during practice. Approximately 23% of the participants reported a previous injury of the OMF area, while approximately 56% reported injuries in other areas. Most dental injuries (94%) were tooth fracture or displacement, while 6% were tooth avulsion. Eight participants (12%) were aware of the possibility of returning an avulsed tooth to its socket. More than 50% of those participants had inadequate knowledge on the appropriate storage media for the avulsed tooth or the maximum time allowed to return it to its socket. Eighty-one percent of the participants knew about the mouthguard, while 56% reported that they are actually using one. The most frequently reported barriers for not using a mouthguard during practice were difficulty in practicing with it, not being convinced of its importance, and lack of information where to get one.Conclusions:Most of the participants are aware of OMF injuries; however, their knowledge and behavior towards preventing and managing them are inadequate.
Background
Dental radiographs are essential tools for diagnosis. However, there are significant concerns about the dangerous effect of radiation especially on children. The aim of this study was to evaluate genotoxicity and cytotoxicity in the exfoliated cells of buccal mucosa of children subjected to Cone Beam Computed Tomography (CBCT).
Methods
The study included 18 healthy children aged (9–12 years) who were exposed to CBCT. All CBCT scans were performed with the i-CAT CBCT. Exfoliated buccal cells were scraped from the left and right cheek immediately before the exposure, after 10 ± 2 days, and after 1 month. Cells were stained using Feulgen/fast green stain and examined under light microscopy. Genotoxicity (Micronuclei) and cytotoxicity (condensed chromatin, karyorrhexis, pyknosis, and karyolysis) were scored. Statistical analysis was performed using the McNemar test, Wilcoxon Signed-Rank test, and Mann-Whitney U test at a significance level of p < 0.05.
Results
There were statistically significant differences in the mean percentages of micronuclei, condensed chromatin, karyorrhexis, pyknosis, and karyolysis before and 10 ± 2 days after the CBCT scan (p < 0.05). There were no statistically significant differences in the frequency of micronuclei, condensed chromatin, karyorrhexis, or pyknosis before and 1 month after the exposure (p > 0.05) except for karyolysis (p < 0.05).
Conclusions
CBCT may induce genotoxicity and cytotoxicity in buccal mucosa cells of children. Therefore, CBCT should not be prescribed unless necessary as it cannot be considered a risk-free procedure.
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.
