    Comparative evaluation of combined remineralization agents on demineralized tooth surface
    (Wolters Kluwer Medknow Publications, 2019) Aras, A.; Celenk, S.; Dogan, M. S.; Bardakci, E.
    Objectives: The aim of this in vitro study was to evaluate the effects of casein phosphopeptides (CPP)-ACPF, NovaMin+ fluoride-containing toothpaste and Xylitol+ fluoride containing cream on demineralized areas on the enamel surface. Materials and Methods: A total of 100 enamel slab samples was prepared to investigate in the laboratory experiments. For this purpose, a total of 50 freshly extracted third molar teeth which completed root formation split into two portions in the mesiodistal direction. Enamel surfaces were immersed in a pH cycling protocol as described in the literature to simulate oral conditions for 9 days in order to evaluate the effect of test materials on the artificial enamel lesions. Then the remineralization agents were applied on the enamel surfaces, and we analyzed their effects. Results: We used Vickers Microhardness with the purpose of calculating the amount of lost or acquisition of minerals on the enamel surface qualitatively; inductively coupled plasma atomic emission spectroscopy (ICP-AES) to define the calcium and phosphorus ions that dissolved in acid. One-way ANOVA and Tukey's T Post-Hoc tests were performed to distinguish significant differences among groups (P < 0.05). Conclusions: Remineralization was provided in all treated groups, according to the data obtained from all tests. NovaMin was more effective in increasing acid resistance. It was also found that all three experimental groups were effective in increasing the surface hardness, but CPP-ACPF and NovaMin are more effective than Xylitol. However, there was no statistically significant difference between the experimental groups.

    Evaluation of mental foramen location in the 10-70 years age range using cone-beam computed tomography
    (Wolters Kluwer Medknow Publications, 2017) Gungor, E.; Aglarci, O. S.; Unal, M.; Dogan, M. S.; Guven, S.
    Introduction: Mental foramen (MF) locations were determined according to gender and age in terms of the vertical distance from the surrounding anatomical structures and the vertical and horizontal size of the MF. Materials and Methods: One hundred-seven male and 103 female patients in the age group between 10 and 70 years were included in our retrospective study and were examined using cone-beam computed tomography (CBCT). The right and the left MF locations were determined from panoramic and cross-sectional images. On the cross-sectional CBCT images, the distance of the MF upper limit from the alveolar crest edge, the distance of the MF lower limit from the lower edge of the mandible, and vertical size of the MF were measured. Results: MF location differed in males and females (P < 0.001); it was generally located at the first and second premolar in females, and at the level of the second premolar in males. However, the MF location was not different on the right and left sides (P = 0.436). The distance of the MF from the surrounding anatomic structures were found to be lower in females than in males in all measurements (P < 0.001). The horizontal size of the MF was found to be less on the left side (P < 0.001). Conclusions: Knowing both the position and the distance of the MF from the surrounding anatomical structures is not only useful information for surgery, but will also help avoid complications such as paresthesia.

    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.
