White spots (WS) are one of the most undesirable side effects in patients undergoing orthodontic therapy and are usually located around bracket bases and even detected under the molar bands. The aim of the present cross-sectional study was to evaluate the WS lesion during orthodontic therapy and the correlation between WS and oral hygiene habits. Patients requiring orthodontic treatment with a fixed appliance were screened for the inclusion/exclusion criteria, and 74 subjects were finally enrolled. Each patient received three examinations: at T0, the day of the application of the fixed appliance; at T1, three months later; and at T2, six months after treatment start. After calculating descriptive statistics, differences between groups were evaluated with an independent sample t-test. The first type error was set as p ≤ 0.01. The observed prevalence of WS lesions was 59.5% on T1 and 60.8% on T2. The most affected teeth result to be upper molars, lower left first molar, upper right central incisor and upper left lateral incisor, upper right canine, upper left first premolar, and lower right first molar. A higher frequency of daily tooth brushing was accompanied by a lower prevalence of WS. No significant effect of sex was observed.
Aim:To map psychological problems amongst undergraduate dental students with a focus on different time points in clinical work in seven Eastern European and Scandinavian countries. Materials and Methods:A total of 1063 3rd-and 5th-year dental students (response rate 70%) participated in this pilot study and completed a pre-tested, structured questionnaire, which collected information on sociodemographic characteristics and self-reported psychological problems. Data were analysed by bivariate and multivariate methods. Results:The majority of participants were female and were younger than male participants. Most participants, though more females than males, agreed that the clinical work of dentistry was psychologically difficult. Almost half of participants felt nervous before working with patients (N = 506, 48%) and experienced a lot of stress whilst working with patients (N = 488, 46%); almost one-third (N = 287, 27%) felt anxious/worried after working with patients. Being a 3rd-and 4th-year student (vs 5th-year) reduced the odds for anxiety after working with patients; being a 3rd-year student (vs 5th-year) increased the odds for stress whilst working with patients.Studying in countries other than Norway reduced the odds for stress whilst working with patients. Less than good self-perceived health, presence of psychological health complaints before starting dental education, female gender and lack of physical activity increased the odds for psychological problems. Conclusion:A high number of undergraduate dental students reported psychological problems in connection with clinical work. It is unlikely that "one size fits all"; therefore, further qualitative investigations on stressors in clinical learning environments should be done in order to design tailor-made supportive strategies.

Hyperesthesia is related to increased sensitivity of dental tissues to mechanical, chemical and thermal stimuli. The aim of this prospective clinical trial was to compare the effectiveness of a calcium-fluoride-forming agent (Tiefenfluorid®, Humanchemie GmbH, Alfeld, Germany) with that of a fluoride varnish (EnamelastTM, Ultradent Inc., Cologne, Germany) in the treatment of dental hyperesthesia in adult patients. In total, 176 individuals (106 females and 70 males, aged 18–59 years old) diagnosed with dental hyperesthesia (DH) were enrolled. The main clinical symptoms were hyperesthesia from coldness and sweetness during chewing; the types of clinical lesions were also determined and recorded. The patients were selected randomly and divided into two groups: (i) the first group of 96 patients was treated with Tiefenfluorid® applied in three appointments at 7-day intervals; (ii) the second group of 80 patients was treated with EnamelastTM, applied seven times at 7-day intervals. All the patients were recalled 7 days, 14 days, 1 month, 3 months, and 6 months from the last application. At the baseline and during every follow-up visit, the DH was measured with a pulp tester. A random intercept/random slope model was used to evaluate the effect of the treatment, at various times with respect to the initial diagnosis. Within the limits of the present study, Tiefenfluorid® was more effective than EnamelastTM against DH in that it provided long-lasting results, with a significant improvement still detected at the latest 6-month follow-up.
This report presents the proceedings of a workshop held in Constanta, Romania on 22 May 2014. During the workshop, representatives from 18 Central and Eastern European countries gave oral presentations on the current oral health of children and young adults aged 16 years and younger. The aim of the workshop was to collect and present data relating to the oral health of children from Central and Eastern European countries and to discuss them in the context of the political changes that have taken place over the last two decades and the recent economic crisis.The presenters had previously completed a series of questions on oral epidemiological studies, prevention of oral disease, treatment and payment, dental personnel, uptake of oral health care and other considerations and structured their presentations on these topics plus the influence of the economic crisis on oral health. It should be remembered that this paper is a report of the proceedings of a workshop and not a study. Ethics approval is not required for workshops.After the 18 oral presentations a 90 min discussion took place during which further points were raised. The presentations, the discussion and the conclusions which were reached are reported in this manuscript.
Objective To investigate and compare the factors that motivated students to study dentistry in countries with similar background (Albania, Croatia and the Republic of Northern Macedonia) and to assess whether or not their motivation changed during time. Material and methods In 2014/2015, cross-sectional studies were conducted in state funded dental schools in Tirana (Albania), Zagreb (Croatia) and Skopje (Macedonia) to assess student views on their career motivation. All dental students from the first, third and final years of study were invited to participate. The participation was voluntary and anonymous. A five-item questionnaire was translated into languages of the participating countries. Ethics approval was granted by the Ethics Committee of the University of Saints Cyril and Methodius, Skopje. The Chi square test was used to test if there were statistically significant differences in answers between students in 3 countries, furthermore between years of the study. Results The total number of respondents was 739 (319 in Tirana, 211 in Zagreb and 208 in Skopje) The differences in the answers between the first-year students from all three countries were statistically significant (χ 2 =82.65; p<.01). The most striking answer was to the question on parents' pressure to study dentistry, which was far more frequent in Tirana (up to 27.7%). A "positive image" was the most frequent response from students from Zagreb (up to 79.7%), but it declined from the first to the final year in Skopje. There were also significant differences between the schools within the 3 rd and final years of study. Conclusions A positive image of dental profession was the main reason for students studying dentistry at all three schools; as many as 97% of the students of the final year in Croatia, a member of the European Union (EU). In the two non-EU countries (Albania, Macedonia) it seemed that dental profession does not have such good status and student expectations are not being fulfilled, especially in Skopje (up to 33.9% willing to change their vocation and up to 64.5% lost their motivation to study) One of the strategies to improve the situation could be to include more clinical practice and to better organize the study..
