    Effect of Saliva Contamination on the Sealing Properties of Glass Ionomer Sealants Placed Over Er,Cr:YSGG Laser-Etched Fissures
    (2017) Oter, B. I.; Tirali, R. E.; Ozgul, B. M.; Berk, N.; Cehreli, S. B.; 0000-0001-6487-3984; 29254347; AAD-2907-2020; AAZ-1977-2021; AAD-6138-2021
    Aim This study investigated the effect of laser pretreatment in reducing the microleakage of conventional (GIC) and resin-modified glass ionomer (RMGIC) sealants on saliva-contaminated enamel. Materials and methods Study Design: 80 extracted non-carious third molars were randomly assigned to two groups (n=40/each): Group A enamel pretreatment with erbium, chromium:yttrium, scandium, gallium, garnet (Er,Cr:YSGG) laser; and Group B no pretreatment. Each group was divided into two subgroups (n=20/each) based on presence/absence of saliva contamination following laser pretreatment. In subgroups: fissures were sealed with GIC (n=10) or RMGIC (n=10). Microleakage was evaluated quantitatively using an image analysis toolkit (Image]), and the data were statistically analysed. Results In the absence of laser pretreatment, the GIC sealant demonstrated significantly lower microleakage values than RMGIC counterparts on both uncontaminated and saliva-contaminated enamel (p<0.001, Mann-Whitney U test). Conclusion Among the tested combinations, GIC sealant with Er,Cr:YSGG pretreatment may be the best approach for sealing pits and fissures, when saliva contamination is inevitable before sealant application.

    Dental Anxiety and Oral Health-Related Quality of Life in Children Following Dental Rehabilitation under General Anesthesia or Intravenous Sedation: A Prospective Cross-Sectional Study
    (2018) Guney, S. E.; Araz, C.; Tirali, R. E.; Cehreli, S. B.; 0000-0002-4927-6660; 0000-0001-6487-3984; 30297563; AAJ-4576-2021; AAD-2907-2020; AAD-6138-2021
    Purpose: The study aimed to investigate dental anxiety and oral health-related quality of life among children undergoing dental rehabilitation under general anesthesia (GA) and intravenous sedation (IVS). Materials and Methods: Participants were 99 healthy children aged 3-5 or 6-12 years operated under GA or IVS. Dental anxiety before treatment and 1 month postoperatively were measured using the Frankl behavior scale (FBS), the venham picture test (VPT), the early childhood oral health impact scale (ECOHIS), and the children's fear survey schedule-dental subscale (CFSS-DS). Data were analyzed using Student's t-test and Mann-Whitney U-test. Results: ECOHIS scores decreased in all groups. VPT scores increased in the 3-5-year-olds treated under GA (P = 0.003). Postoperative CFSS-DS anxiety scores were lower in IVS groups. FBS scores were significantly higher for both age groups (P < 0.001). There was no effect of numbers of extracted or treated teeth. Conclusions: Dental rehabilitation under GA and IVS improved the quality of life and dental behavior. In the 6-12-year-olds, there was no statistically significant difference between children undergoing dental operations under GA and those undergoing dental operations under IVS. Dental anxiety decreased in 3-5-year-olds after treatment under GA but not after IVS.
