Objective: to evaluate, through a questionnaire, the knowledge of undergraduate students of dentistry at Veiga de Almeida University about dental avulsion. Material and Methods: a structured questionnaire with academic background, previous experience on the subject, and multiple choice questions about knowledge of tooth avulsion was applied to undergraduate students of dentistry from the 2nd to the 8th semester. Results: 98.2% of students knew what is dental avulsion and 54.5% have studied or had some kind of education on the subject, 92% answered that dental replantation is the best procedure in case of avulsion. However, only 31% effectively knew how to proceed and proper care of the avulsed tooth (41%). Regarding tooth storage, 61% would store in a bottle of fresh milk. 81% of participants believe that the avulsed tooth, after reimplantation, should be immobilized. Conclusion: undergraduate dentistry students at Veiga de Almeida University present knowledge about the definition of tooth avulsion and that replantation is the best option for treatment. However, it is observed that due to the care of the avulsed tooth and the care protocol, students' knowledge is scarce.
The aim of this study was to evaluate the gingival condition and stress level of the military during field training. Thirty militaries were clinically evaluated at two times (1st and 10th - last day of the mission), by probing pocket depth (PPD), visible plaque index (VPI), and gingival bleeding index (GBI). After the clinical evaluation, the soldiers answered a stress questionnaire in both moments. The difference between the 1st and last day of the mission was verified by the Friedman and Wilcoxon tests and the correlation between stress x GBI and stress x VPI by the Spearman test (p<0.05). There was higher PPD (0.98mm), VPI (8.0%) and GBI (13.5%) on the last day of the mission, when compared to the first (PPD = 0.92mm; VPI= 5.2% and GBI = 10.2%), with significant statistical difference. Regarding the regions (anterior and posterior teeth), a higher VPI was observed in anterior (11.7%) than in posterior teeth (1.1%) on the first day (p=0.013); and in posterior teeth, between the first (1.1%) and last day (5.5%) (p=0.005). In the GBI, there was a difference for posterior teeth between the first (10.3%) and last day (14.9%) (p=0.004). One patient (3.3%) had initial symptoms of stress and,3 patients (10%) in the last day (p>0.05). There was no correlation between stress and gingival conditions. The military demonstrated a higher incidence of VPI and GBI at the end of the mission, especially in the posterior teeth. However, the stress was similar at the beginning and end of the mission.
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.
