    Caries-related salivary parameters and oral microbial flora in patients with type 1 diabetes: A meta-analysis
    (Wiley, 2022) Hatipoglu, Omer; Onsuren, Asli Sogukpinar; Hatipoglu, Fatma Pertek; Kurt, Ayca
    Objectives This study aimed to conduct a meta-analysis by synthesising the outcomes of studies that investigated the relationship between type 1 diabetes (T1D) and salivary flow rate (SFR), salivary pH (SpH), salivary buffer capacity (SBC), streptococcus Mutans (SM), and lactobacillus (LB) counts. Material and Methods The PRISMA statement guide was followed for the meta-analysis. Electronic databases were searched, and study selection and data collection processes were performed. The risks of bias in individual studies and across studies were assessed. Mean differences (MD) and Odds Ratio (OR) were used to measure the effect estimates in the comparisons. Results 29 studies were included in the qualitative and quantitative syntheses. Significantly higher SFR (MD = -0.22, CI: -0.26, -0.18; p < 0.001) and SpH (MD = -0.59, CI: -0.81, -0.36; p < 0.001) were observed in the healthy individuals than T1D individuals. No significant difference was observed among groups in terms of SBC (MD = 0.10, CI: -0.46,0.66; p = 0.73). An increased odds ratio of SM counts were observed regarding the T1D (OR = 3.09, 95% CI: 1.16, 8.20; p = 0.02). No association was found between LB counts and T1D (OR = 2.15, 95% CI: 0.38, 11.98; p = 0.38). Conclusions Subjects with T1D have a significantly lesser SFR and SpH than healthy individuals. But no significant difference is available in terms of SBC. Lower SM counts were observed in individuals with T1D, while no association was observed regarding LB counts. The tendency to dental caries is more likely in subjects with T1D due to lower SFR, SpH, and higher SM.

    Influence of Thermo-Light Curing on the Microhardness and Fluoride Release of Glass-Ionomer Cements
    (Technical Assoc Photopolymers,Japan, 2024) Kurt, Ayca; Atlas, Ay Mete; Arslan, Ipek; Tuzuner, Tamer; Bayg, Ozgul; Sokmen, Munevver; Altntepe, Lkay
    Glass ionomer cements (GICs) are important restorative materials that are frequently preferred in both primary and permanent teeth. The aim of this study was to investigate the effect of thermo-light curing on the surface microhardness and fluoride ion (F - ) release of the materials during the curing reactions of high -viscosity GICs. In our study, Equia Fil (EQGC), Fuji IX GP Extra (FGP-GC), and Fuji IX Capsule (FC-GC) were prepared in accordance with the manufacturer's instructions, and for 60 and 90 seconds during curing Woodpecker LED -C (WL), GC D -Light Pro (GLC) and BlueLuxcer M-855 Halogen Curing Light (HALO) light instruments formed the experimental groups, and self -curing glass ionomer cement samples formed the control groups. VHN and Frelease values of both groups were evaluated on 1st day, 1st week, 1st, 3 rd , and 6th months. The Jamovi (Version 1.0.4) program was used for statistical analysis. Significant difference was analyzed by the Tukey's post hoctest (a = 0.05). In the 1st month, EQ exhibited significantly higher microhardness than FC (p<0.05) but not with FGP (p>0.05). All materials exhibited higher microhardness during 1st day than in other periods (p<0.05). In terms of Frelease, there were significant differences between materials on the 1st day (p<0.05). EQ, FC, and FGP exhibited higher Frelease, respectively. In the 1st, 3rd, and 6th months, EQ exhibited released significantly higher Fsignificantly (p<0.05), whereas this amount was similar between FC and FGP (p>0.05). Within the limitations of this study, it can be concluded that thermo-light application does not cause unacceptable long-term changes in the physical and chemical properties of materials.

    Potential Renal Acid Load, Salivary Buffer Capacity and Healthy Eating Index as Predictors of Children's Dental Caries: A Cross-Sectional Study
    (Springernature, 2023) Kibaroglu, Elif; Kurt, Ayca; Ozbek, Yagmur Demirel; Saral, Ozlem; Hatipoglu, Omer
    Introduction: Dental caries is one of the most common childhood diseases. This study purposed to investigate the prediction capability of potential renal acid load (PRAL), salivary buffer capacity (SBC), and Healthy Eating Index (HEI) on children's dental caries. Methods: The decay, missing, filing, and teeth for primary teeth (dmft)/Decay, Missing, Filling, and Teeth for permanent teeth (DMFT) indexes of the children aged 7-12 years who applied to our faculty were recorded. Approximately 1 mL of unstimulated saliva samples were collected, and SBC was evaluated. PRAL and HEI scores were calculated by entering the data in the form of a daily nutrition record of the children into the BeBiS software (Ebispro for Windows, Stuttgart, Germany). The association of dental caries indices with PRAL, SBC, and HEI was analyzed using an independent sample t -test. A binomial logistic regression analysis was performed to predict the dental caries burden. The statistical significance level was adjusted to a=0.05. Results: A total of 150 children, 88 (58.6%) females and 62 (41.4%) males, were included in the study. Significant differences were found between the low and high dental caries groups for dmft regarding PRAL and SBC (p<0.001). A significant difference was found between the low and high dental caries groups for DMFT in terms of SBC (p<0.05). Conclusion: In our study, established regression models significantly predicted dental caries in primary teeth. SBC was the most influential factor in predicting dental caries compared to PRAL and HEI. There was a significant relationship between SBC, PRAL, and caries in primary teeth. In the model we created, the strongest predictor was SBC.
