    Impact of a Surface Sealant Application on the Color Stability of a Nano-hybrid Composite Resin

    Objective: Mouthwashes containing chlorhexidine can cause discoloration in restorative materials when used for the long-term. To prevent staining of a restorative material, several protective materials are used. The aim of this in vitro study was to evaluate the impact of a surface sealant on the color stability of a nano-hybrid composite resin material immersed in different mouthwashes.Methods: A total of 42 composite resin discs (10 x 2 mm) were prepared with a nano-hybrid composite resin (Herculite XRV Ultra) using Teflon moulds. The composite specimens were first divided into two groups (with or without a surface sealant) then into three subgroups (n = 7) according to the mouthwashes (Gengigel, Oderol, and Klorhex). After SS application to 21 specimens, all the discs were subjected to baseline color measurements using a spectrophotometer according to the CIE L*a*b* system. The specimens underwent thermal cycling. Following immersion in different mouthwashes for 24 hours, the color measurements were repeated. The ΔE data were assessed using Kruskal-Wallis one-way ANOVA. Mann-Whitney U test was performed for different immersion mouthwashes (p<0.05).Results: Statistically significant differences (p<0.05) were found between the unsealed composite specimens immersed in Klorhex and the other mouthwashes in terms of ΔE values. The Klorhex appeared to be associated with the most severe alteration in color (5.14±0.83), followed by Gengigel (2.21±1.46) and Oderol (1.94±1.75). There were no statistically significant differences (p>0.05) between the sealed and unsealed composite specimens in terms of the color changes.Conclusion: The application of a low viscosity liquid surface sealant material did not show the expected effect on the color stability of a nano-hybrid composite resin in terms of three different mouthwashes.Keywords: Color change, mouthwash, surface sealant, composite resin, thermal cycling

    Perceptions of dental students towards online education during the COVID-19 pandemic
    (2021-12-01T00:00:00Z) Sarıalioğlu Güngör, Ayça; Dönmez, Nazmiye; SARIALİOĞLU GÜNGÖR, AYÇA; DÖNMEZ, NAZMİYE
    Purpose: This study evaluated the usage habits, attitudes, and perceptions of undergraduate dental students toward distance (online) learning and identified variables related to those attitudes. Materials and methods: The study included 1,605 undergraduate dental students who participated voluntarily. The data collection tool consisted of a distance learning attitude scale, a questionnaire on personal information, and open-ended questions. The perceptions of dental students to distance education according to the year and type of dental school they attended were evaluated. Results: Most students expressed that distance learning in dental courses was not as effective as traditional face-to-face education (59.1%, n=949). While students studying at state universities had a more negative view of distance education, the satisfaction scores of the first-year students were found to be significantly lower than the other students (p<0.05). Conclusion: Dental students were generally unhappy with the interruption of traditional education caused by COVID-19 and having to continue their education online. However, under the circumstances, they saw it as an advantage allowing them to continue their education and avoid a complete suspension.

    The Effect of Whitening Dentifrices on the Surface Roughness of Different Composite Resins

    Aim: The aim of this in-vitro study was to evaluate surface roughness (SR) of two different composite resins after toothbrushing with different whitening toothpastes.Materials and Methods: Filtek Z250 universal composite resin (3M) (3M ESPE, St. Paul, MN, USA) containing bis-GMA and Charisma Topaz (CT) nano-hybrid composite resin (Heraeus Kulzer, Wehrheim, Germany) without bis-GMA were used in the study. 50 disc-shaped specimens of 10 mm in diameter and 2 mm in thickness were prepared from each composite. The prepared discs were kept at 370C for 24 hours and then separated in 5 subgroups: G1 control (artificial saliva) group, G2 Colgate Optical White Active Charcoal (containing active carbon), G3 Yotuel (containing carbamide peroxide), G4 Opalescence (containing abrasive particle), and G5 Sensodyne, Promine (containing fluoride) pastes (n = 10).After initialmeasurements and SR1 values were recorded.The discs were brushed in continuous mode with an electric toothbrush (Triumph Professional Care, Oral B Braun GmbH, Kronberg / Ts., Germany) in a slurry (1:3 g/ml) of the tested toothpastes (1.5 N). Samples were brushed twice a day for 4 weeks and 8 weeks to mimic the daily routine. Samples were conserved in artificial saliva between brushing cycles. After 4 weeks and 8 weeks cycles, SR2 and SR3 values were recorded. The obtained data were analyzed by three-way mixed ANOVA.Results: There were no statistically significant differences between the two composite resin materials (p=0.575). When the whitening dentifrices groups were compared f o r both ma t e r i a l s , there was no statistical difference after 4 weeks and 8 weeks. The SR value of the control groups (0,948 ± 0,118 3M, 1,006 ± 0,187 CT) were significantly lower than the Charcoal groups (1,672 ± 0,314 3M, 1,653 ± 0,265 CT) at the end of 8 weeks (p<.05).Conclusion: After simulated brushing with whitening toothpastes, similar degree of roughness was observed on the composite resins tested.Keywords: surface roughness, toothbrushing, whitening toothpaste, resin composite
