Objectives:The aim of this study was to obtain information about senior dental students’ perceptions and self-confidence levels regarding endodontic practice.Materials and Methods:Anonymous survey forms were handed out to senior students at Yeditepe University, Faculty of Dentistry. The students were asked to score their level of confidence using a 5-point scale and comment about future practices.Results:The response rate of the survey was 88%. 11.9% expressed endodontics as the first branch in terms of difficulty. The majority (90.5%) indicated they would perform root canal treatments within their expertise limit in the future but refer difficult cases to an endodontist. Bleaching of endodontically treated teeth, managing flare-ups, placement of a rubber dam were procedures in which students reported the lowest confidence (2.55 ± 1.17, 3.24 ± 0.96, 3.24 ± 1.19, respectively). On the other hand, students felt the lowest confidence in the treatment of maxillary molars followed by mandibular molars (3.43 ± 1.02 and 3.93 ± 0.97, respectively). Students also reported the lowest confidence in root resorptions, endo-perio lesions, traumas, retreatments and apexifications (2.93 ± 1.16, 3.07 ± 0.89, 3.24 ± 0.85, 3.33 ± 1.7 and 3.36 ± 1.1, respectively).Conclusions:The results showing students’ lower confidence in more challenging aspects of dentistry may be related with the attitude of dental schools to refer these cases to post graduate students and instilling information about these cases on a theoretical basis only. Though there seems to be a tendency for students to refer challenging cases to a specialist in future, authorities should give priority to enhance the way information and experience is conveyed regarding various aspects of endodontic treatment.

The purposes of this study were to obtain information about the social and demographic proile of students enrolled in the irst private Turkish dental school, to gather information regarding the reasons for their preferences, and to obtain data about their career expectations. Questionnaires were distributed to 278 students; 229 returned the survey for an overall response rate of 82 percent. Of the respondents, 145 (65.5 percent) were females and seventy-ive (34.5 percent) were males; they had an average age of 21.62±1.58. First degree relative (mother, father, sibling) had the greatest inluence on the students in choosing dentistry as a career. Fathers and mothers had similar impact on the students' choice of dental profession (45.9 percent and 46.6 percent, respectively). Humanistic feelings, desire to serve others, and reasonable working hours were the predominant reasons that motivated females to become a dentist (p<0.05). Also, academic interest and interest in a medical ield were signiicantly inluencing factors for female students (p<0.05 and p=0.001, respectively). One-hundred and ninety-seven students (86 percent) expressed a goal of specializing in a speciic branch of dentistry; orthodontics and oral and maxillofacial surgery were the top-ranked specialties. Although only 41 percent of the students were of Istanbul origin, 82.5 percent reported that they wish to practice in Istanbul.Dr. Tanalp is Associate Professor,

The present study evaluated the possible effects of exposure to polypropylene flock on respiratory health and serum cytokines in a cross-sectional study of workers from a plant in Turkey.A total of 50 polypropylene flocking workers were compared to a control group of 45 subjects. All subjects filled out a respiratory questionnaire and underwent a physical examination, a chest radiograph and pulmonary function testing, including single breath carbon monoxide diffusing capacity (DL,CO). Serum interleukin-8 (IL-8) and tumour necrosis factor-alpha (TNF-a) were measured. Additionally, high resolution computed tomography (HRCT) of the chest was performed in 10 exposed workers with low DL,CO.Work-related respiratory symptoms were reported in 26% of the exposed subjects and in 13.3% of the controls. Logistic regression analysis showed that the risk of respiratory symptoms increased 3.6 fold in polypropylene flocking workers when compared to controls. Parameters of the study group, including per cent predicted: forced vital capacity, forced expiratory volume in one second, forced mid-expiratory flow 25-75% and DL,CO, were significantly lower than in controls. Multivariate analyses showed that being a polypropylene flocking worker was a predictive factor for impairment of pulmonary function. Serum IL-8 and TNF-a levels were increased in the study group compared with the controls. HRCT revealed peribronchial thickening and diffuse ground glass attenuation in some subjects.The present study suggests the presence of subtle or the beginning of interstitial lung disease in these polypropylene flocking workers.

Dental education programs are known to be highly stressful and stress can affect general health. The aims were to identify sources of stress among preclinical students and to evaluate their perceived levels of stress, self-efficacy and effective coping strategies in a private dental school. One hundred preclinical students in a Turkish private dental school were surveyed using dental environment stress (DES), perceived stress (PSS), general self-efficacy (G-SES) and brief coping scales (Brief-COPE). Age, gender, history of psychiatric treatment, factors that affected the choice of dentistry, choice rank of dental school, scholarship and income was recorded. 'Exams and grades' followed by 'Fear of failing course or year' were found to be the most stressprovoking factors. The most and the least stressprovoking DES domains were 'Workload' and 'Social stressors', respectively. 'Social stressors' affected male more than female (p < .05). The most and the least common coping strategies were found to be 'Planning', and 'Drug', respectively. Female used 'Instrumental support' more than male (p < .05). Demographic factors had impact on the perceived stress factors and levels, as well as coping strategies. Unlike previous studies establishing high stress levels in dental students, preclinical students displayed moderate level of stress. Clinical dental education might be more responsible for creating stress.

The present findings imply that HC has a significantly higher impact on better management of diabetes and oral health when compared to formal HE. This calls for the use of HC by dentists, physicians, and diabetes educators in order to improve quality of life of DM2 patients by facilitating better oral health and diabetes self-management.
