Publication Metadata only Knowledge and attitudes concerning diet and dental health in a group Turkish students(2006-09-07) BEKİROĞLU, GÜLNAZ NURAL; KARGÜL, BETÜL; Erzengin Ö. U., Kargül B., Alyan M., Öktem S. N., Bekiroğlu G. N.Publication Open Access Effect of Remineralization Agents on Molar-Incisor Hypomineralization-Affected Incisors: A Randomized Controlled Clinical Trial(2022-01-01) KARGÜL, BETÜL; SEZER B., KARGÜL B.Objective: The objective of this study was to evaluate the remineralization effect of two different mineral containing agents on white/creamy and yellow/brown demarcated opacities in incisors in children with molar-incisor hypomineralization (MIH) by using laser fluoresence (LF). Study Design: Fifty-three children (n=401 lesions) with MIH were randomly divided into three groups: (1)calcium glycerophosphate (CaGP), (2)casein phosphopeptide amorphous calcium fluoride phosphate (CPP-ACFP) and, (3)control (1450 ppm fluoride toothpaste). Remineralization was evaluated by means of LF, at baseline, after one and threemonths. Anova Test for Repeated Measurements in intra-group comparisons in evaluating the effectiveness of remineralization agents. One-way Variance Analysis (ANOVA) and Tukey-Kramer Multiple Comparison test were used in the comparisons between groups and, Student Newman Keuls Multpile Comparison Test was used to determine the differences between the measurement averages in case of p<0.05. Results: There was a significant improvement in MIH-lesions over time in all groups (p<0.001), with no differences between groups. The highest percentage of change was observed in CPP-ACFP in lesions LF≤20 scores and the mean percentage of change LF>20 scores, the highest percentage changes in CaGP. There was no significant difference between the groups over the time for all the used outcome measures (p>0.05). Conclusion: The additional use of both mineral containing agents in MIH-affected teeth improved these hypomineralized lesions with mineral deposition. Even if both agents could be used in the hypomineralized teeth with demarcated opacities, future studies are recommended the long-term effect of these mineral containing agents with longer observation and a larger sample size.

N., Kargül B.Publication Metadata only The effect of a single application of different fluoride varnishes on enamel subsurface lesions in vitro(2022-04-01) ŞEN YAVUZ, BETÜL; YILMAZ, MÜESSER AHU; OKTAY, NİHAL ŞEHKAR; KARGÜL, BETÜL; Yildiz P. K., ŞEN YAVUZ B., YILMAZ M. A., OKTAY N. Ş., KARGÜL B.This in vitro study aimed to evaluate the therapeutic effect of different fluoride ion (F) varnish formulations for controlling the carious development of enamel subsurface lesions and the F release into artificial saliva for 2 hr, 24 hr, 48 hr, and 7 days. Artificial enamel carious lesions were created and divided into 6 groups (5 varnish groups and a control group). Varnishes were applied to enamel specimens and then the specimens were incubated in artificial saliva, with the artificial saliva replenished daily. Varnish was removed and lesions were remineralized in artificial saliva for 24 hr. Surface microhardness was measured three times: (i) initially, (ii) after creating the artificial enamel lesions, and (iii) after applying the varnishes. The F release was analyzed after 2 hr, 24 hr, 48 hr, and 7 days of exposure using an ion-selective electrode. Data were analyzed using a One-way Analysis of Variance with the Tukey-Kramer Multiple Comparisons test and the Kruskal-Wallis test with the Dunns Multiple Comparisons test. The highest percentage surface microhardness recovery was found for the treatment with the MI Varnish. According to the percentage surface microhardness recovery results, a statistically significant difference was found between the varnishes and the control group (p < 0.05 and < 0.001). All varnishes released measurable levels of fluoride ions. However, the release of F was the highest in the MI Varnish group (p < 0.01). Duraphat, Enamel Pro Varnish, and MI Varnish released the most F into artificial saliva. Calcium phosphate-based F varnishes improve the capacity of the enamel surface re -hardening. CPP containing F varnish had the highest release of F as compared to the other F releasing varnishes. Further in vivo investigations are also required to prove the clinical applications of the different ingredients containing varnishes.Publication Metadata only Demirjiyan’s system for estimating dental age among Northwestern Turkish children aged 1-16 years(2012-04-10) BEKİROĞLU, GÜLNAZ NURAL; KARGÜL, BETÜL; Erçalık Yalçınkay Ş., Dumlu A., Bekiroğlu G.

N., Çiçek N., ALPAY H., KARGÜL B.Objectives: The aim of this study was to investigate the association between serum biomarkers and oral health parameters in children with chronic kidney disease (CKD). Materials and methods: Serum hemoglobin, blood urea nitrogen, serum creatinine, calcium, parathormone, magnesium, and phosphorus levels were measured in 62 children with CKD aged between 4 and 17 years. Intraoral examinations of the patients were performed by two different pediatric dentists. Dental caries was assessed using the decayed-missing-filled-teeth (DMFT/dmft) indexes, and oral hygiene was assessed using the debris (DI), calculus (CI), and simplified oral hygiene (OHI-S) indexes. Spearman’s rho coefficient and generalized linear modeling were used to examine the association between serum biomarkers and oral health parameters. Results: The results of the study showed that there were negative and statistically significant correlations between serum hemoglobin and creatinine levels and dmft scores in pediatric patients with CKD (p = 0.021 and p = 0.019, respectively). Furthermore, blood urea nitrogen levels and DI and OHI-S scores (p = 0.047 and p = 0.050, respectively); serum creatinine levels and DI, CI, and OHI-S scores (p = 0.005, p = 0.047, p = 0.043, respectively); and parathormone levels and CI and OHI-S scores (p = 0.001 and p = 0.017, respectively) were found to be positively and statistically significantly related. Conclusions: There are associations between various serum biomarker levels and dental caries and oral hygiene parameters in pediatric patients with CKD. Clinical relevance: The impact of changes in serum biomarkers on oral and dental health is important for dentists’ and medical professionals\" approaches to patients\" oral and systemic health.Publication Metadata only Validity and reliability of Turkish version of th child perception questionnaire in 11-14 year old children by rasch analysis(2012-04-10) KARGÜL, BETÜL; Günel Karadeniz P., Özbay G., Kargül B., Bekiroğlu G. N.Publication Open Access Changes in oral health-related quality of life after treatment of molar incisor hypomineralisation using Glass Hybrid Restorations(2022-10-01) TUĞCU, NİHAN; SEZER, BERKANT; DURMUŞ, BAŞAK; KARGÜL, BETÜL; TUĞCU N., SEZER B., Caliskan C., DURMUŞ B., KARGÜL B.Objective: To assess the changes in children\"s oral health-related quality of life following the treatment of severely affected molar-incisor hypomineralisation with Glass Hybrid Restorative System (GH) after selective caries removal. Method: The observational cross-sectional study was conducted at the Marmara University, School of Dentistry, Department of Pediatric Dentistry, Istanbul, Turkey.. Children aged 11-14 years (n = 55) who were diagnosed with MIH and had finished their dental treatment from November 2018 to December 2019, were included. The children\"s MIH-affected teeth were treated with GH after SCR. Participants answered the Child Perceptions Questionnaire (CPQ11?14) prior to their dental treatment and 6 months after the treatment. Results: Of the fifty-five patients, 40 patients (24 girls-16 boys) completed baseline and follow-up data. The mean age of the children was 11.85 +/- 1.02 years. The overall CPQ score ranged from 3-83 (average 33.27 +/- 16.46) at baseline and 0-61 (average 11.67 +/- 11.21) at follow up. The emotional well-being among children was the highest score at baseline. A significant decrease (p < 0.001) in the mean values was observed for both the overall CPQ scores and for the scores of the oral symptoms, functional limitations, and social-emotional well-being limitation. All subdomains showed large effect sizes and oral symptom limitation domain presented the greatest effect. Wilcoxon Rank test was used to determine the statistical significance of the changes and the magnitude of change was determined by calculating and classifying the effect size. Conclusion: Restorative treatment with GH following selective caries removal positively influenced the oral health -related quality of life of children with severe molar-incisor hypomineralisation.Publication Open Access Is there an association between molar incisor hypomineralization and developmental dental anomalies? A case-control study(2023-12-01) ŞEN YAVUZ, BETÜL; KARGÜL, BETÜL; ŞEN YAVUZ B., SEZER B., Kaya R., Tuğcu N., KARGÜL B.Background: The aim of this study was to determine whether there is any association between molar incisor hypomineralization and developmental dental anomalies. Methods: Two pediatric dentists evaluated panoramic radiographs of 429 children aged 8–14 years with molar incisor hypomineralization (study group) and 437 children without molar incisor hypomineralization (control group) in terms of developmental dental anomalies. Twelve different developmental dental anomalies were categorized into four types: size (microdontia, macrodontia); position (ectopic eruption of maxillary permanent first molars, infraocclusion of primary molars); shape (fusion, gemination, dilaceration, taurodontism, peg-shaped maxillary lateral incisors); and number (hypodontia, oligodontia, hyperdontia) anomalies. Results: No significant difference was observed in the frequencies of developmental dental anomalies between the study and control groups in total, females, and males (p > 0.05). A statistically significant difference was found between the distribution of developmental size, position, shape, and number anomalies between the study and control groups (p = 0.024). The most common anomaly in both groups was hypodontia (6.3% and 5.9%, respectively). There was a significant difference between the study and control groups in terms of subtypes of shape anomaly in all children and females (p = 0.045 and p = 0.05, respectively). Conclusions: While a significant difference was observed between the distributions of types of developmental dental anomalies between individuals with and without molar incisor hypomineralization, there was no difference in terms of the frequency of developmental dental anomalies.
