    Fluoride concentration in urine after silver diamine fluoride application on tooth enamel
    (Iop Publishing Ltd, 2017) Sari, D. L.; Bahar, A.; Gunawan, H. A.; Adiatman, M.; Rahardjo, A.; Maharani, D. A.; Toptanci, I. R.
    Silver Diammine Fluoride (SDF), which contains fluoride, is known to inhibit tooth enamel demineralization and increase fluoride concentrations in saliva and urine. The aim of this study is to analyze the fluoride concentration in urine after application of SDF on tooth enamel. Urine from four subjects was collected prior to, 30 minutes after, and two and three hours after the application of SDF, and an ion-selective electrode was used to measure the fluoride concentrations. There was no significant difference between time 1 and time 2, time 1 and time 3, time 1 and time 4, time 2 and 3 (p > 0.05), and there was a significant difference between time 2 and time 4 as well as time 3 and time 4 (p < 0.05). There was a decrease in the concentration of fluoride ions in urine from the baseline to 30 minutes after application, and an increase from baseline to two and three hours after the application of SDF.

    Microleakage of Glass Ionomer based Restorative Materials in Primary Teeth: An In vitro Study
    (Wolters Kluwer Medknow Publications, 2018) Ayna, B.; Celenk, S.; Atas, O.; Tumen, E. C.; Uysal, E.; Toptanci, I. R.
    Aim: Using AutoCAD, we examined the microleakage of dye at the edges of primary-teeth restorations using three glass ionomer-based restorative materials. Materials and Methods: A total of 30 extracted noncarious primary molars were used. Class V cavities were adjusted on the buccal surfaces. The teeth were randomly divided into three groups of 10 teeth each as follows: Group A (Ketac Molar), Group B (Photac Fil), and Group C (Dyract XP). All specimens were stored for 24 h at 37 degrees C in distilled water. The teeth were thermocycled 1000 times between 5 degrees C +/- 2 degrees C and 55 degrees C +/- 2 degrees C before immersion in 0.5% basic fuchsin for 24 h. Two mesiodistal cuts of each tooth were photographed under a stereomicroscope equipped with a digital camera. The dye-infiltrated surface area was measured. Statistical evaluations were performed by the Kolmogorov-Smirnov test, Levene test, one-way analysis of variance, and Tukey's honestly significant difference test. Results: The mean microleakage ratio differed significantly among the groups (P < 0.05). Group C exhibited a significantly smaller area (P < 0.001) than the other groups. Group A had a nonsignificantly higher mean microleakage value than Group B (P > 0.05). Conclusions: Polyacid-modified composite resin may be a useful restorative material in primary teeth in terms of minimizing microleakage.

    The reliability of microleakage studies using dog and bovine primary teeth instead of human primary teeth
    (Ariesdue Srl, 2013) Yavuz, I.; Tumen, E. C.; Kaya, C. A.; Dogan, M. S.; Gunay, A.; Unal, M.; Toptanci, I. R.
    Aim This was to investigate if dental restorations on human, dog and bovine primary teeth are equatable for microleakage analysis, and the respective marginal adaptation deficiency in in vitro conditions. Materials and methods In order to determine the level of microleakage in Class V polyacid-modified composite restorations of human, dog and bovine primary teeth, samples were evaluated by dye-leakage method in sections of the inner area of the restorations. Results We found no leakage in 6 out of 10 (60%) human restorations, in 7 out of 10 (70%) of dog and in 7 out of 10 (70%) of bovine teeth. The levels of dye-microleakage were tested with Kruskal-Wallis one-way variant analysis method. The relative leackage differences were not statistically significant among all species (p>0.05). Conclusion We concluded that dog and bovine primary teeth might be suitable for in vitro studies instead of human ones.
