Purpose: The current literature shows a growing interest to assess the feelings and perceptions of students associated with the performance of elective endodontic procedures. This study aimed to evaluate the students' anxiety and self-perceptions related to performing such treatments.Methods: Forty-five students participated in the research (G1 = 22 beginners students; G2 = 23 senior students). Demographic data, STAI-State and Numerical Rating Scale (NRS) for pre-operative anxiety were completed before the appointment with patient. The STAI-Trait; NRS for post-operative anxiety; previous experiences in endodontics; and level of confidence in each stage of endodontic treatments were collected after appointment. Focal groups for qualitative data collection were performed on separate occasion.
Results:Both groups showed higher scores in STAI-State than for STAI-Trait scale. G1showed higher levels of anxiety in the pre-operative, compared with post-operative moment in the NRS scale. G2 reported feeling more confidence to insert intracanal medication and to restore teeth between appointments than G1. In both focus groups, participants reported insecurity in performing endodontic procedures due to difficulty in visualisation and to anatomic complexities. G1 reported that all the confidence they had was based in pre-clinical experience, and G2 mentioned concern about the end of graduation.
Both quantitative and qualitative analysis showed different anxiety levels in dental students. It can possibly contribute to a reduction in confidence prior to emergency endodontic procedures. The current findings suggest it might be important to rearrange activities in order to allow for more practical classes in Endodontics.
Despite advances in the characterization of developmental dyslexia (DD), several questions regarding the interplay between DD-susceptibility genes and environmental risk factors remain open. This systematic review aimed at answering the following questions: What has been the impact of new resources on the knowledge about DD? Which questions remain open? What is the investigative agenda for the short term? Forty-six studies were analyzed. Despite the growing literature on DD candidate genes, most studies have not been replicated. We found large effects on causative genes and smaller environmental contributions, involving maternal smoking during pregnancy, SES and the DYX1C1-1259C/G marker. Implications are discussed.
Protecting and nurturing offspring have been crucial to human evolution. For that reason, babies are very salient emotional stimuli to human beings. The current study compared the emotional interference of baby and adult faces on the automatic attention in 61 parents and nonparents (36 women, 20–35 years old; parents [n = 33] had a single child aged up to 2 years old). Images of distressed, happy, and neutral baby faces, and fearful, happy, and neutral adult faces, were used in a go/no-go paradigm to assess attentional bias. Attentional bias indexes were calculated for biases toward baby distress, baby versus adult faces, and adult fear. Parents showed a higher attentional bias toward baby versus adult faces (M = 17.62, SD = 50.52) than nonparents (M = −8.52, SD = 32.39), F(1) = 5.39, p = .024, η2 = 0.08. This bias was independent of the emotion expressions in the face stimuli. This study demonstrates that parental status influences attentional bias toward baby faces in men and women, and contributes further to the literature that previously focused mainly on women.
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.
