Leakage testing for different adhesive systems and composites to permanent teeth

Aim: To explore the microleakage of different adhesive systems and flowable composites to permanent teeth. Subjects and Methods: In this study, a total of 84 human premolar teeth were used. Class V cavities were prepared on the buccal surfaces. The teeth were randomly assigned to six groups of 14 teeth each as follows: The first group – etch-rinse adhesive applied and cavities filled with flowable composite, the second group – etch-rinse adhesive applied and cavities filled with bulk-fill resin composite, the third group – one-stage self-etch (SE) adhesive applied and cavities filled with flowable composite, the fourth group – one-stage SE adhesive applied and cavities filled with bulk-fill resin composite, the fifth group – two-stage SE adhesive applied and cavities filled with flowable composite, and the sixth group – two-stage SE adhesive applied and cavities filled with bulk-fill resin composite. All specimens were then stored for 24 h at 37°C in distilled water. Teeth were then thermocycled for 500 cycles between 5°C and 55°C prior to immersion in 0.5% basic fuchsin for 24 h. Two mesiodistal cuts of each tooth were photographed for leakage with a digital camera. The dye infiltrated surface for each specimen was measured and data were collected with a software program. Statistical evaluations were done by nonparametric Kruskal–Wallis test and Mann–Whitney U-test. Results: There were statistically significant differences in mean microleakage ratio among the groups (P < 0.05). The first group had shown significantly increased microleakage areas than the other four groups (third, fourth, fifth, and sixth groups) (P < 0.05), except for the second group (P > 0.05). It was also no significant different between the mean microleakage areas of group fourth and group fifth (P > 0.05). The sixth group had exhibited the lowest microleakage areas, and it was statistically significant (P < 0.05) compared to the other groups. Conclusion: In this study, it has been found that the use of total etch adhesive systems resulted in high leakage values.

The Prevelance of Tobacco Use and the Factors Influencing in Students Studying at Two Dentistry Faculties in Turkey

OBJECTIVES The objective of this study was to determine the pattern and effects of tobacco and tobacco products use among students of dentistry. MATERIAL AND METHODS A cross sectional study was performed in the Dentistry Faculty of Ege and Dicle Universities between April and May 2013. All freshmen and senior year students receiving education in both universities were included into the study (n= 321). A questionnaire consisting of 26 questions was used to determine the smoking habits of the students and the influencing factors regarding this habit. Students replied the questions under supervision. RESULTS A survey was conducted among 298 students out of 321 who were attending both universities. 46.6% of the participants were female and 53.4% were male. Smoking prevelance of the students was 29.9%. It was 19.9% in freshmen students and 45.8% in senior students. According to the first class of students in the fifth grade students in the prevalence of smoking in was found to be highly statistically significant (p< 0.001). Among other tobacco products the following was identified as mostly used: waterpipe, also known as narghile (27.4%), cigarwraps (9.7%), cigar (9.4%) and smoking pipe (2.0%). While 22.5% of the students stated that they started smoking after the age of 15, 36.0% started between the ages of 15 and 18 and 41.5% after the age of 19. The rate of smoking in the house was significantly higher (p< 0.001) among smokers than non-smokers. While 78.7% of the students stated that they would like to quit, 64.3% tried once or more to quit. CONCLUSION Smoking habit was found to be higher among medical students than the social average. Smoking is more frequent in higher classes. From early years onwards, students of dentistry should be intensively educated regarding the harmful effects of tobacco on health, and efforts should be made to prevent and control of tobacco epidemic.

Evaluation of children’s dental anxiety levels at a kindergarten and at a dental clinic

This study evaluated the dental anxiety levels of preschool children at a kindergarten and at a dental clinic. The anxiety levels of ninety 4-6-year-old (4.99 ± 0.81) preschool children were evaluated according to pulse rates, the facial image scale (FIS), the Venham picture test (VPT), and the Frankl behavior rating scale. The childrens mothers were asked to complete the state-trait anxiety inventory (STAI) forms 1 and 2 (STAI 2 and STAI 2). The sample t-test, Mann-Whitney U test, and Pearsons correlation test were used. A statistically significant difference was observed between the childrens pulse rates when measured at the dental clinic and those when measured at the kindergarten (p < 0.001). Although the results were not statistically significant, more negative facial expressions were observed in the children at the dental clinic than in those at the kindergarten when assessed using FIS and VPT (p = 0.090 and p = 0.108, respectively). There was a statistically significant correlation between the transient anxiety levels (STAI 1) of mothers and the VPT scores of their children evaluated at the dental clinic (r = 0.506, p < 0.001). The continuous anxiety level of the mothers of males was found to be significantly higher (p = 0.033) than that of the mothers of females (STAI 2). Although the children had been informed about dentistry and were introduced to a dentist at the kindergarten, their anxiety levels seemingly increased as they arrived at the dental clinic. The significant increase observed in the childrens pulse rates was a physical indicator that their anxiety levels had increased. It can be concluded that the children felt more anxious at the dental clinic that at the kindergarten.
