The MMI is reliable, acceptable and feasible. The evidence base for its validity against future medical council exams is growing with reports from longitudinal investigations. However, further research is needed for its acceptability in different cultural context and validity against future clinical behaviours.
This study investigated the relationship between emotional intelligence (EI) and perceived stress (PS) in dental undergraduates. All dental undergraduates attending a UK dental school were invited to complete a questionnaire on age, gender, year of study, EI, and PS. Two hundred and thirteen students (48 percent male) participated, a response rate of 70 percent. The mean score for EI was 117.54 (S.D. 14.90) and PS was 17.73 (S.D. 6.49). Factor analysis confirmed four factors previously identified in the literature as comprising emotional intelligence: optimism/mood regulation, utilization of emotions, appraisal of emotions, and social skills. T-tests indicated that females had significantly higher EI scores than males. Mean PS scores were significantly higher for students aged over twenty-one years compared with those aged twenty-one years or less (p<0.001), female compared to male students (p<0.05), and those in higher years compared to those in lower years of study (p<0.001). Correlational analysis showed an inverse relationship between EI and PS. Multiple regression analysis identified year of study, optimism/mood regulation, and gender as independent, significant predictors of PS. In conclusion, low EI scorers report more PS. Future research should investigate the relationships of EI and PS with impact on lifestyle behaviors, academic and clinical performance, and health outcomes.
BackgroundTo determine the root canal morphology of human permanent maxillary and mandibular teeth in a Malaysian subpopulation using cone-beam computed tomography (CBCT).MethodsA total of 208 CBCT images were examined retrospectively. Prevalence of an extra root/canal and internal morphology based on Vertucci’s classification were observed in human maxillary and mandibular permanent teeth. Variations in the external and internal morphology were compared in relation to gender and tooth side (left vs right) using Pearson Chi-square and Fisher’s exact tests with significance level set at p < 0.05.ResultsIn the maxillary arch, the prevalence of three canals were observed in 0.3% of first premolars and two canals in 46.5% of second premolars. Males displayed significantly higher prevalence of two canals in maxillary second premolars than females (p < 0.05). The prevalence of a second mesiobuccal canal in maxillary first and second molars were 36.3 and 8.5%, respectively. Males displayed significantly higher prevalence of a second mesiobuccal canal in maxillary second molars than females (p < 0.05). The prevalence of a second palatal canal in maxillary first and second molars were 0.9 and 0.6%, respectively. In the mandibular arch, the prevalence of two canals were observed in 5.1% of central incisors, 12.3% of lateral incisors, 6.1% of canines, 18.7% of first premolars and 0.5% of second premolars. The prevalence of a middle mesial canal, second distal canal and extra root (radix entomolaris) were detected in 1.9, 19.5 and 21.4% of mandibular first molars, respectively. The prevalence of a C-shaped canal was observed in 48.7% of mandibular second molars. Females displayed significantly higher prevalence of a C-shaped canal in the right mandibular second molars than males (p < 0.05). No other statistically significant differences in root anatomy and root canal morphology were observed in relation to gender and tooth side.ConclusionsWide variations in the root canal morphology exist among Malaysians. CBCT is a clinically useful tool in the identification of external and internal morphological variations in the human teeth.
Objective: To explore how dental undergraduates with different levels of emotional intelligence (EI) cope with stress. Design: Qualitative unstructured depth interviews. Setting: A dental teaching hospital in the UK, 2002. Subjects and Methods: Subjects selected from the undergraduate population of a 5-year dental degree course. A questionnaire survey was carried out to determine the EI scores of the subjects. In each year of study, subjects were divided into low and high EI groups at the median score. From each EI group in each year, one male and one female subject were recruited. Data collection Unstructured face-to-face interviews. Data analysis Transcribing, sifting, indexing and charting data according to key themes. Results: 10 males and 10 females with low and high EI, representing all 5 years of study were interviewed. The experience of stress, expressed in emotional terms, ranged from anger and frustration to hatred. Four sets of coping strategies, adopted at varying degrees according to EI, were identified. High EI students were more likely to adopt reflection and appraisal, social and interpersonal, and organisation and time-management skills. Low EI students were more likely to engage in healthdamaging behaviours. Conclusions: Future research needs to establish whether the enhancement of EI in dental students would lead to improved stress-coping, and better physical and psychological health.
This multinational survey investigated the relationship between emotional intelligence (EI) and perceived stress (PS) in seven countries. First-year dental undergraduates attending a dental school in England, Greece, Romania, South Africa, Australia, and the United States and three schools in Malaysia were invited to complete a set of questionnaires on age, gender, academic background, satisfaction with career choice, EI, and PS. Of 860 questionnaires distributed, 596 were fully completed-a response rate of 69.3 percent. Mean EI score was 123.8 (95 percent CI 122.7-124.9), and mean PS score was 19.1 (95 percent CI 18.6-19.7). Significant differences in EI and PS scores were detected between different countries. Females (p<0.05), younger students (p<0.001), those without a previous higher education qualification (p<0.001), and those not satisfied with their decision to study dentistry (p<0.001) were more likely to report PS when compared to their counterparts. A significant inverse relationship (coef-ficient=-0.29, p=0.001) between EI and PS was detected. Independent significant predictors of PS identified were gender (ß=0.22, t=5.71, p=0.001), previous higher education qualification (ß=-0.14, t=-2.42, p=0.010), satisfaction with decision to study dentistry (ß=-0.20, t=-5.11, p=0.001), and EI (ß=-0.24, t=-6.09, p=0.; 0044(0)2073777632 phone; 0044(0)2073777064 fax; a.k.pau@qmul.ac.uk.
