(Kerman Univ Medical Sciences, 2019) Yayli, Nazli Zeynep Alpaslan; Tunc, Serap Keskin; Kaki, Gulter Devrim; Altindal, Dicle
BACKGROUND AND AIM: The purpose of this study was assessing oral health status and dental anxiety differences between the freshman and senior dental students and the effect of awareness on dental practices. METHODS: Freshman (n = 71) and senior dental students (n = 41) were included in this study. All participants were applied Corah Dental Anxiety Scale (C-DAS) and asked for the frequency of dental visits in a year. Gingival index (GI), plaque index (PI), bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL), and decayed, missing, and filled teeth (DMFT) index were recorded. Number Cruncher Statistical System (NCSS) program and Shapiro-Wilk, t, Mann-Whitney U, Pearson chi-square, and Fisher-Freeman-Halton tests were used for statistical analysis (P < 0.0500). RESULTS: C-DAS score of the freshman students was found significantly higher than the senior students (P < 0.0500). There was a statistically significant difference in the frequency of dental visits between freshman and senior students (P < 0.0010). GI, PI, and BOP values of the freshman students were significantly higher than the senior students (P < 0.0010). There was no statistical differences between PD and CAL measurements (P > 0.0500). It was found that the DMFT index of freshman students was significantly higher than the senior students (P < 0.0010). CONCLUSION: This study has shown that dental anxiety decreases as awareness and consciousness increase in terms of dental practice. More anxious participants' oral health is weak, individuals with high dental anxiety make fewer visits to the dentists and need more dental practices.
The Effects of Chelation on the Adhesion of Two Different Root Canal Sealers
(Taylor & Francis Ltd, 2018) Kaki, Gulter Devrim; Sen, Ozgur Genc
Objective: This study aims to evaluate alterations in the root canal dentin after irrigation with EDTA, HEBP, and Chitosan in order to determine the push-out bond strengths of the different root canal sealers on altered dentin surfaces. Materials And Methods: Crowns of 70 maxillary single-rooted teeth were removed to obtain a standardized length of 16mm. The canals were instrumented using rotary files and the step back technique. The master apical file used in this study was #40. The subgroups were determined based on the chelation agent and the material of the root canal sealer that was used (17% EDTA, 18% HEPB, 0.2% Chitosan, Well Root ST (WRST) or AH Plus). Three slices with 1mm thickness were cut from the root thirds of each tooth and subjected to a push-out test. The data (MPa) were analyzed using a one-way ANOVA and a Duncan's multiple comparison test at a level of =0.05. Finally, scanning electron microscope (SEM) photographs were taken. Results: Groups that used WRST exhibited significantly higher push-out bond strength values in all subgroups independent of the irrigant that was used (ANOVA, p<0.05). Group 1 showed higher push-out bond strength than the other AH Plus subgroups. Conclusion: The EDTA improved the push-out bond strength of the AH Plus. The WRST root canal sealer had the highest push-out bond strength and did not depend on the irrigant used.
