Assessment of Stress among Doctors of Dental MedicineProcjena razine stresa doktora dentalne medicine Uvod Stres je pojam koji označava stanje organizma u kojem doživljavamo prijetnju svojem integritetu (1,2). Podražaje koji ga uzrokuju nazivamo stresorima. Ako između stresora ne postoji razdoblje potrebno za oporavak nego se nižu jedan za drugim, pojavljuje se kronični stres koji izaziva ozbiljne zdravstvene posljedice (2, 3). Reakcija pojedinaca na stres rezultat je individualne osjetljivosti, načina svladavanja poteškoća, cjelokupnog zdravstvenog stanja, vanjskih utjecaja i stresora (2, 4). Reakcije mogu biti psihološke, ponašajne i fiziološke (5).Svjetska zdravstvena organizacija proglasila je stres na radnome mjestu svjetskom epidemijom (6, 7). Svako radno mjesto može biti rizično za pojavu određenih bolesti, ali određena se zanimanja smatraju stresnijima, a među njima i zanimanje doktora dentalne medicine (2, 8). Stomatolozima mnogi čimbenici na poslu mogu potaknuti stres. Neki od njih su klinički rad, nepovoljni radni uvjeti, rad s nervoznim i anksioznim pacijentima, rad koji nerijetko pacijentu uzrokuje bol, vremenski pritisak i ograničenja te izloženost promjenama koje nužno nameću kontinuiranu izobrazbu radi što boljeg obavljanja radnih zadataka. To su opći stresori s koji-Abstract Introduction: The workplace can be a source of stress. One of the most stressful professions is the profession of doctor of dental medicine (dentist). Multiple forms of stressors lead to such occupational stress. Objective: The research objective was to examine stress levels among dentists in the 25 to 45 year age group. Materials and Methods: This cross sectional study included 105 doctors of dental medicine throughout Bosnia and Herzegovina, aged between 25 and 45 years. The research was conducted by means of a confidential on-line survey. All participants signed the informed consent, and voluntarily filled out the survey form. The research used the PERCEIVED STRESS SCALE-PSS 10. The statistical analysis used the IBM Statistics SPSS v.21 statistics packages and Microsoft Excel 2010. Descriptive statistics, X2 test, and T-test were also used. Results: Of the total number of respondents, n=105, 66 (63%) of them were female and 39 (37%) male respondents. The mean median value of the score was 23 (Mean = 23.080), as a result of which we can conclude that the respondents in the 25-45 year age population group that participated in this study showed a high level of stress based on the completed questionnaire and the answers received from the respondents. Conclusion: The estimated level of stress has been shown to be high in both genders, with no statistically significant difference between genders.

Background: Periodontal complications are one of the common side effects associated with orthodontic therapy. Objective: This study aimed to evaluate the periodontal changes in patients before, during, and after the therapy with a fixed orthodontic appliance. Methods: Out of 38 healthy adolescents with permanent dentition who were indicated for fixed orthodontic therapy were included in this study. Patients were selected from Class I, treated by non-extraction methods, by using conventional orthodontic braces. After their examination and treatment by an orthodontist, the patients were referred to the periodontist before the placement of a fixed orthodontic appliance. The patients underwent the application of a periodontal anamnestic-diagnostic protocol, and the clinical-radiological evaluation. After a fixed orthodontic appliance was placed, the respondents were referred to the periodontist for regular mandatory check-ups, initially, after three months, and later on–after 6 months, after 1 year and after 2 years until the end of orthodontic therapy. Results: An increase in the mean value of the Plaque Index and Sulcus Bleeding Index was found at each check-up after the placement of a fixed orthodontic appliance. There is a statistically significant difference in the presence of gingival hyperplasia found by monitoring the changes after three and six months, and after one and two years following the start of orthodontic therapy. Conclusion: The assessment of periodontal changes in patients before, during and after the completion of fixed orthodontic therapy revealed that there is a strong need for mutual and close cooperation between orthodontist and periodontist during orthodontic therapy.

SummaryBackground/Aim: Potentially malignant oral lesions (PMOL) are lesions that have an increased risk of malignant transformation concerning healthy oral mucosa. This research aimed to assess the knowledge of students of final years of study on the potentially malignant lesions of the oral cavity.Material and Methods: 120 students of the fourth and fifth years of study participated in this research,60 respondents were fourth-year students, 60 respondents were fifth-year students. All of the respondents signed informed consent.According to the type of research, this is a cross-sectional study which was conducted by completing a 15-item questionnaire. The results were statistically analyzed and processed in the SPSS Statistics 21.0 program.Results: The results indicate that during the clinical examination the fourth and fifth-year students examine the oral mucosa as well. 61% of the students find themselves poorly informed on the PMOL. In the fourth year of study, only 5,5% of students responded that they were well informed, while in the fifth year that number totaled 28,5%. When knowledge self-assessment is concerned the difference has shown itself to be statistically significant between the fourth and fifth-year students. When asked what knowledge on the prevention of oral cancer they expect to receive during their studies, 78% of the students expected more knowledge than at that moment – 36% of which were fifth-year students, and 42% were fourth-year students.Conclusions: Even though the oral cavity is easily accessible to examination, the discovery of oral cancer occurs quite late. Ours, as well as results of other studies, impose the need for better theoretical and practical education of the students.

Background: Dentine hypersensitivity (DH) is a frequent clinical problem that represents a long-term painful discomfort for the patients, and for the dentists, it represents a diagnostic and therapeutic challenge. Objective: The aim of the research is to verify the effect of the treatment with diode laser SiroLaser Blue (660nm) of DH alone or in combination with different impregnating agents. Methods: Fifty patients were included in this research, separated into five groups. All the patients have been asked to define the level of dentine hypersensitivity using VAS (0-10). The first group was treated with Fluor Protector, the second group after the application of Fluor Protector has undergone irradiation with SiroLaser Blue (660nm), the third group was treated with impregnating agent Vivasens, the fourth group, after the application of impregnating agent Vivasens, has had SiroLaser Blue (660nm) irradiation. The fifth group has just been treated with SiroLaser Blue (660nm). The efficiency of the treatment was checked using VAS for every group immediately after the conducted treatment, after 7 days and 1 month. Results: Our results showed that all of the desensitizing agents used in the research alone or in combination with a diode laser (660nm) have shown a reduction of DH. The difference has been proven statistically significant in mean values by groups and examinations. Vivasens and diode laser irradiation have provided the best results in the review of mean values after the first examination and one month after the treatment of DH (p<0,05). In our research, the application of diode laser alone has not proven superior to other treatment methods that have been used in the research. Conclusion: Vivasens plus diode laser irradiation has provided the best results even after one month since the treatment of DH.
