Öğe 7-15 Yaş Arası Çocuklarda Dental Anksiyete Sıklığı Ve Ebeveynlerin Anksiyetesi İle İlişkisi(2020) Sert, Tuğba; Oba, Aylin Akbay; Arıkan, Volkan; Şahin, Necibe DamlaBu çalışmanın amacı, okul çağındaki çocuklar arasındaki dental anksiyete düzeyini değerlendirmek ve çocukların dental anksiyetesini ebeveynleri ile karşılaştırmaktır. Toplam 304 çocuk ve ebeveynleri çalışmaya dahil edilmiştir. Çocukların yaşı 7-15 arasında değişmektedir. Dental muayene yapılmadan önce her çocuktan bağımsız olarak Çocuk Dental Anksiyete Ölçeği (CFSS-DS) anketini doldurması istenmiştir. Ebeveynler arasında dental anksiyeteyi değerlendirmek için dental anksiyeteyi beş seviyede kategorize eden, Modifiye Dental Anksiyete Ölçeğinin (MDAS) Türkçe versiyonu kullanılmıştır. Yaş, eğitim düzeyi ve ebeveynlerin mesleki durumu gibi demografik veriler kaydedilmiştir. Muayene edilen 304 çocuğun (176 kız, 128 erkek) 77’sinde (%25,3) (CFSSDS ? 38) dental anksiyete saptanmıştır. Çocukların anksiyete seviyeleri ile cinsiyetleri ve yaşları arasında ilişki tespit edilememiştir. Ebeveynlerin 42'sinde (%13,9) dental anksiyete olduğu bulunmuştur. Ebeveyn MDAS skorları ve CFSS-DS ile ölçülen çocuk dental anksiyetesi arasında pozitif korelasyon tespit edilmiştir (r = 0.410, p <0.05). Bu bulguların, çocukların dental anksiyetesini önleyecek veya hafifletecek müdahalelerin tasarlanmasına yardımcı olabileceği düşünülmektedir. Böylece ebeveynlerin dental anksiyetesi azaltılarak, çocukların dental anksiyetesi de azaltılabilir veya önlenebilir.Öğe Antibacterial activity of fluoride varnishes containing different agents in children with severe early childhood caries: a randomised controlled trial(SPRINGER HEIDELBERG, 2020) Almaz, Merve Erkmen; Oba, Aylin AkbayObjectives The aim of this study was to compare the antibacterial activity of fluoride varnishes containing different agents in children with severe early childhood caries (S-ECC). Materials and methods The study was conducted in 92 children with S-ECC. Patients who completed dental treatment under general anaesthesia were included in the study. Patients were divided randomly into four groups: 5% sodium fluoride (SF) control group (n = 23), 5% SF with tricalcium phosphate (TCP) (n = 23), 5% SF with xylitol-coated calcium and phosphate (CXP) (n = 23) and 5% SF with casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) (n = 23). Saliva mutans streptococci (MS) and lactobacilli (LB) levels were evaluated by taking saliva samples at baseline (T-0), 1 month (T-1) and 3 months (T-2) after treatment. Results All groups showed a significant decrease in MS and LB levels at T-1 (P < 0.05) except the CXP group. Only the TCP group exhibited significantly decrease MS and LB levels indicating less than 10(5) CFU at both T-1 and T-2 compared with the other groups (P < 0.05). Conclusion Fluoride varnish with TCP provided significantly more reduction in MS and LB levels than other fluoride varnishes. Clinical Trials registration number NCT03625310Öğe Apical microleakage of various biomaterials in simulated immature apices(2019) Tulumbacı, Fatih; Arıkan, Volkan; Oba, Aylin Akbay; Sönmez, IşılBackground:In the treatment of open apex teeth, one-step apexification has been reported as an alternative method to the use of long-term calcium hydroxide. Materials and Methods: The present study evaluated and compared apical microleakage when ProRoot MTA (Dentsply) (Group I), DiaRoot BioAggregate (Diadent) (Group II) and Biodentine (Septodont) (Group III) were used in the endodontic treatment of the teeth with simulated immature apices. To simulate immature teeth, 57 bovine maxillary incisor roots were prepared and randomly divided into three groups (n = 15 per group). The remaining teeth were included in negative (n=6) and positive (n=6) control groups. The materials were prepared according to the manufacturer’s instructions and a radiograph was taken for each sample to confirm proper obturation of the samples. Apical microleakage was assessed using the dye penetration technique. Linear dye penetration was measured at 30X magnification and the data were analyzed using One-way ANOVA.Results:Group I showed the lowest apical leakage with a mean dye penetration of 4.64 mm (±SD), whereas the leakage was highest in Group II with a mean dye penetration of 5.45 mm (±SD). The difference between the leakage in Group I and II was statistically significant (p<0.05), but the differences between other groups (Group I-III and Group II-III) were not (p > 0.05).Conclusion:Based on the findings of this study, we conclude that the MTA and BD (especially Al) have the best sealing ability among the tested materials for treatment of obturated immature teeth.Öğe Bitkisel içerikli bir lolipopun tükürük streptoccus mutans düzeyleri üzerine etkisinin değerlendirilmesi(Kırıkkale, 2014) Oba, Aylin Akbay…Öğe Clinical Evaluation of a Colored Compomer in Primary Molars(Karger, 2009) Oba, Aylin Akbay; Sönmez, Işıl Saroğlu; Sarı, ŞaziyeObjective: The purpose of this study was to evaluate the clinical performance of a new colored compomer material, Twinky Star, in primary molars. Subjects and Methods: Eighty class II restorations were placed in a total of 36 subjects and the clinical success of the restorations was evaluated after 12 months based on modified US Public Health Services criteria. Results: The failure rate of the restorations was 3.9% ( 3 out of 77) and the clinical success of the restorations, measured by anatomic form, marginal integrity, marginal discoloration, surface texture, maintenance of interproximal contact and secondary caries, was acceptable. Conclusion: The clinical success of the colored compomer material, Twinky Star, indicates that it could be a good alternative to tooth colored compomers. Copyright (C) 2008 S. Karger AG, BaselÖğe Çocuk Hastalarda Gelişimsel Dental Anomalilerin Görülme Sıklığı ve Dağılımı(2017) Almaz, Merve Erkmen; Şaroğlu, Işıl Sönmez; Oba, Aylin AkbayAmaç: Bu çalışmanın amacı; Kırıkkale Üniversitesi Diş Hekimliği Fakültesi, Pedodonti Kliniği'ne başvuran çocuk hastalarda gelişimsel dental anomali görülme sıklığının değerlendirilmesidir.

This study was designed to compare caries prevention with high-viscosity glass ionomer cement (GIC) sealants placed according to the ART procedure and light-cured composite resin sealants after 3 years. Methods: The study was conducted in a boarding school in the city of Kirikkale. Four experienced dentists placed a total of 207 sealants (91 GIC and 116 composite resin), without chair-side assistance, on the school premises. Results: A total of 137 sealants were available after 3 years. 55.3% of the GIC and 93.8% of the composite resin sealants were lost completely, and the difference between the two groups was statistically significant. Only six of 56 teeth in the GIC group and eight of 81 in the composite resin group showed caries. Conclusion: Under field conditions in which moisture control was not effective, a high-viscosity and less technique-sensitive glass ionomer material can be used as an effective sealant material, rather than resin. [J Formos Med Assoc 2009;108(11):844-848]Öğe Comparison of Retention Rates of Fissure Sealants Using Two Flowable Restorative Materials and a Conventional Resin Sealant: Two-Year Follow-Up(Karger, 2012) Oba, Aylin Akbay; Sonmez, Isil Saroglu; Ercan, Ertugrul; Dulgergil, TurkselObjective: The purpose of this clinical study was to compare the retention rates of two flowable restorative systems (Admira Flow and Grandio Flow) with that of a conventional resin-based sealant (Fissurit F). Materials and Methods: The study was planned as a clinical trial with a split-mouth design. A total of 122 sealants (38 Admira Flow, 41 Grandio Flow, 43 Fissurit F) were randomly applied to completely erupted permanent molars in 35 patients aged 9-20 years and followed up for 24 months. Data were analyzed using Pearson's chi(2) and multiple comparison tests. Results: At the end of the follow-up period, Fissurit F had higher retention rates (81.0%) than both Admira Flow (60.5%) and Grandio Flow (57.1%), with p < 0.05. However, there was no significant difference in caries development among groups (p > 0.05). Conclusion: The two flowable composite resin materials used as fissure sealant were less retentive than the conventional resin sealant. Copyright (C) 2011 S. Karger AG, BaselÖğe Effect of Er,Cr:YSGG Laser on the Prevention of Primary and Permanent Teeth Enamel Demineralization: SEM and EDS Evaluation(MARY ANN LIEBERT, INC, 2020) Ulusoy, Nur Burcu; Oba, Aylin Akbay; Cehreli, Zafer CavitObjective: To evaluate in vitro the effect of the erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser on resistance of primary and permanent human enamel to demineralization using water cooling and fluoride coapplication as variable parameters. Methods: Enamel specimens were prepared from extracted primary and permanent teeth (n = 225 each). The specimens were separated into 15 subgroups (n = 15/group) based on laser application at three different power settings (0.25, 0.50, and 0.75 W), laser application with and without water cooling, and application of acidulated phosphate fluoride (APF) gel before laser treatment. Morphological changes were assessed with scanning electron microscopy (SEM), and the specimens' chemical contents were determined with energy-dispersive X-ray spectroscopy. Results: In both the primary and permanent teeth, the highest Ca and P content was observed in the noncooled 0.75 W laser group (p < 0.05), irrespective of APF pretreatment (p > 0.05). The Ca and P content for the noncooled APF +0.75 W laser group was lower than that for the APF group and the noncooled 0.75 W laser group. For both dentitions, the F mass content for the APF+laser groups was significantly higher than laser-only groups (p < 0.05). Under SEM, both the primary and permanent enamel exhibited cracks, craters, and surface roughness without water cooling, consistent with increased power output. Conclusions: Er,Cr:YSGG laser application at 0.75 W without water cooling increased enamel resistance to demineralization. Compared with topical APF application, Er,Cr:YSGG laser application barely improved enamel resistance against demineralization, and coapplication did not result in a synergistic effect.Öğe Effects of different fissure sealant applications on laser fluorescence measurements(Wiley, 2011) Sonmez, Isil Saroglu; Oba, Aylin Akbay; Erkmen, Merve; Ekici, SedaObjective. The aim of this in vitro study was to evaluate the effects of using only phosphoric acid or a self-etch bonding agent under clear and opaque fissure sealants on laser fluorescence (LF) readings and the reproducibility of the laser device. Methods. Eighty extracted permanent molars, ranged from sound to carious, were randomly divided into four groups: phosphoric acid + opaque sealant (group I), Clearfil S3 Bond (Kuraray, Kurashiki, Japan) + opaque sealant (group II), phosphoric acid + clear sealant (group III), and Clearfil S3 Bond + clear sealant (group IV). The teeth were measured using an LFpen device, before and after sealing. Data were analysed using the Spearman's correlation, Wilcoxon signed rank, and Mann-Whitney U-test. Results. Except group IV, there was a statistically significant decrease in fluorescence after the application of sealants (P < 0.05). The decrease of LFpen readings in the opaque sealant groups was more significant than the clear sealant groups (P < 0.05). But for both sealants, the difference between phosphoric acid and Clearfil S3 Bond groups was nonsignificant (P > 0.05). Conclusions. There was a statistically significant decrease in fluorescence for both clear and opaque sealant groups. However, clear sealant with Clearfil S3 Bond does not influence the LFpen readings.Öğe Efficacy of a sugar-free herbal lollipop for reducing salivary Streptococcus mutans levels: a randomized controlled trial(Springer Heidelberg, 2017) Almaz, Merve Erkmen; Sonmez, Isil Saroglu; Okte, Zeynep; Oba, Aylin AkbayThe aim of our study was to evaluate the efficacy of an herbal lollipop containing licorice root extract on salivary Streptococcus mutans in caries-free and high-caries-risk children. The study was conducted in caries-free and high-caries-risk children, aged 5-11 years (n = 108). The groups were caries-free children (group A); high-caries-risk children whose dental treatment was completed before lollipop use (group B); and high-caries-risk children who did not comply with dental treatment (group C). The groups were divided into two subgroups: herbal (A-1, B-1, C-1) and placebo lollipops (A-2, B-2, C-2). Saliva samples were taken before dental treatment, before and after consuming lollipops, and at 3 months after consuming lollipops. The results were statistically analyzed with chi-squared test. Only in group C-1 (high-risk, using herbal lollipops) that significant reduction was observed in salivary S. mutans levels after lollipop use (p = 0.033), and only in the same group (C-1), there was significant difference between after lollipop use and third month levels (p = 0.006). Herbal lollipops could be recommended to children with high-caries risk who do not comply with dental treatment in place of high-carbohydrate snacks. The paper provides a perspective on using herbal products in high-risk children for reducing salivary S. mutans counts.Öğe Florid içerikli restoratif materyallerin florid salımı ve floridle yeniden yüklenebilme özelliklerinin değerlendirilmesi*(2020) Karaca, Zehra; Oba, Aylin Akbay; Özalp, Nurhan; Derkuş, Tuğçe Özmen; Taştekin, MustafaAmaç: Bu çalışmanın amacı florid içerikli farklı restoratif materyallerin (Geleneksel cam iyonomer siman, İonofil U; Rezin modifiye cam iyonomer siman, Photac Fil Quick Aplicap; Cam hibrit restoratif materyal, Equia Forte; Cam karbomer, Glass Fil ve Giomer, Beautifil II) in vitro koşullarda florid salım özelliklerini ve floridle yeniden yüklenebilme kapasitelerini karşılaştırmaktır.

Methods: Sixty-six sound human maxillary incisors were randomly divided into 3 groups (n=22). Teeth were embedded in self-cure acrylic resins by leaving one-third of the crowns out, and uncomplicated crown fractures were obtained using an Instron testing device. The fragments were reattached using 3 different procedures and a hybrid resin composite (Z250): Group I: Acid etching + Prime & Bond NT; Group II: Er, Cr: YSGG + Prime & Bond NT; Group III: Er, Cr: YSGG + Acid etching + Prime & Bond NT. The percentages of shear bond strengths were determined by comparing fracture strengths of sound and reattached teeth for 3 groups. All data were analyzed statistically with Kruskal-Wallis H test. Results: Mean fracture strengths of the reattached fragments were between 51.02% and 62.93% of that of the sound teeth in all groups. Group I had significantly higher percentages of shear bond strength values (P < 0.05) when compared to group II and group III. No significant difference (P > 0.05) was found between group II and group III. Conclusion: The findings of the present study show that Er, Cr: YSGG laser irradiation prior to the reattachment of incisal fragments has a negative effect on fracture strength.Öğe Kırıkkale İlinde Yaşayan 3-6 Yaşları Arasındaki Çocuklarda Süt Dişi Dental Erozyon Prevalansının Değerlendirilmesi(2017) Arıkan, Volkan; Vapur, Kamile Nur; Oba, Aylin AkbayAmaç: Bu araştırmanın amacı Kırıkkale’deki çocukların süt dişlerinde dental erozyonun prevelansını ve risk faktörlerini belirleyerek erken teşhis ile gerekli önlemlerin alınmasına yardımcı olmaktır.

Material and Methods The study population comprised of 109 children in the age range 6-12 years. Children were classified as exposed to passive tobacco smoking (PTS-exposed, n=51) and as unexposed controls (PTS-unexposed, n=58). Plaque index, gingival index, bleeding on probing, probing depth and clinical attachment level (CAL) were recorded. GCF, saliva and urine samples were also collected. The levels of cotinine in these fluids were determined by enzyme-linked immunosorbent assay. Results The mean salivary cotinine concentration was significantly increased in PTS-exposed children compared with PTS-unexposed children (p < 0.05). Further, in a dose-dependent way, the mean salivary concentration was significantly higher in children whose father or mother was a smoker (p < 0.05) as compared, respectively, with children whose fathers and mothers were non-smokers. The mean CAL was significantly less in PTS-exposed children compared with non-PTS-exposed children (0.09 mm; p < 0.05) and also in children whose father was a smoker (p < 0.05), but not in children whose mother was a smoker as compared with non-smoker fathers and mothers, respectively. The GCF cotinine levels were below the detection limits with the assay method that was used. Conclusions We have observed that children who are exposed to passive smoking have elevated cotinine levels in their saliva concomitant with a lowered CAL.Öğe Postoperative morbidity in pediatric patients following dental treatment under general anesthesia(Istanbul Univ Press, Istanbul Univ Rectorate, 2019) Almaz, Merve Erkmen; Oba, Aylin Akbay; Sonmez, Isil SarogluPurpose The aims of this study were to investigate post-operative complications in pediatric patients 24 and 72 hours after general anesthesia (GA) and to identify any associations between dental procedures and complications. Materials and Methods One hundred and thirty three healthy pediatric patients who had undergone dental treatment under GA (age range: two to nine years) were included in this study. The project was designed as a prospective, observational study supported by a questionnaire that collected data on children's post-operative complaints. Preoperative data were obtained from patients' files and included age, gender, medical condition and admission type (inpatient or outpatient) variables. The postoperative complaints were assessed either by phone contact or by face-to-face interviews using a questionnaire 24 and 72 hours after treatment. Results 69.9% of children reported one or more complaints after 24 hours and 35.3% after 72 hours. Coughing and pain (27.1%), inability to eat (24.8%), psychological changes (24.1%) and a sore throat (21.1%) were the most common complaints during the first day. After 72 hours, the severity and rate of the complications decreased significantly (p < 0.05). Conclusion Post-operative complaints following dental treatment under GA tended to be of mild severity and were mainly limited to the first day after the procedure.Öğe Prevalence and Distribution of Developmental Dental Anomalies in Pediatric Patients(Galenos Yayincilik, 2017) Almaz, Merve Erkmen; Sonmez, Isil Saroglu; Oba, Aylin AkbayObjective: The objective of this study was to evaluate the prevalence of dental anomalies in paediatric patients attending the Department of Paediatric Dentistry, Kirikkale University Faculty of Dentistry. Materials and Methods: The study consisted a sample of 9173 patients, aged between 0-15 years, referred to our clinic between 1 August 2011-1 August 2012. The patients were examined clinically and radiographically in terms of the number, size, shape, structure and color anomalies. Results: One hundred sixty six children (1.8%) were found to have developmental dental anomalies. The most frequently observed anomalies were congenitally missing teeth (0.52%) and supernumerary teeth (0.27%). Anomalies such as dens invaginatus (0.03%), dentinogenesis imperfecta (0.02%) and dilaceration (0.02%) were encountered more rarely. Conclusion: Early diagnosis and determination of the prevalence of dental anomalies in children is important in the treatment planning.Öğe Prevalence of Dental Anxiety in 7-to 11-Year-Old Children and Its Relationship to Dental Caries(Karger, 2009) Oba, Aylin Akbay; Dülgergil, Çoruh Türksel; Sönmez, Işıl SaroğluObjectives: The aims of this cross-sectional study were to evaluate the level of fear of dental procedures among schoolchildren and assess the relationship between caries experience and fear of dental procedures. Subjects and Methods: 275 children aged 7-11 years were recruited for the study. Before conducting a dental examination, each subject was asked to independently complete a Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) questionnaire. Children having a score of 6 38 were included in the group 'with dental fear' while those scoring ! 38 were placed in the 'without dental fear' group. All dental examinations were performed on the school premises according to WHO criteria. Results: Mean CFSS-DS value was 28.1, and the number of children who experienced dental fear was 40 (14.5%). It was found that Decayed, Missing and Filled Surface Index (DMFS-dfs) increased significantly with increasing CFSS-DS values. Fear scores were highest for 'Choking' (3.3), 'Injections' (2.6) and 'Having somebody put instruments in their mouth' (2.6). No significant differences in fear scores between boys and girls were found in this study. Conclusions: The data showed prevalence of dental fear in the 7-11-year-old children of this study. Dental fear scores decreased with increasing age. Copyright (C) 2009 S. Karger AG, BaselÖğe RADIOGRAPHIC EVALUATION OF THE DEVELOPMENT OF THIRD MOLARS IN CHILDREN AGED 5-15 IN TURKEY(2022) Tozar, Kamile Nur; Oba, Aylin Akbay; Arıkan, VolkanObjective: In this study, it was aimed to determine the age of the onset of crown calcification of third molars in children aged 5-15 years in Turkey, and to evaluate the development status of third molars by age.Material and Methods: Panoramic radiographs of the first 1024 patients between the ages of 5 and 15 years were evaluated. The development (calcification) of third molars was classified according to the Demirjian method.Results: When the onset age of the stages for maxillary and mandibular third molars were compared, no statistically significant difference was found (p?0.05). In addition, although no statistically significant difference was found between genders regarding the age of calcification onset of third molars, it was observed that teeth #28 and #48 developed in boys approximately one year before girls (p?0.05). When the onset age of the stages for maxillary and mandibular third molars were compared, no statistically significant difference was found (p?0.05). Concerning stage 5, in which the furcation zone of third molars begins to calcify, although not statistically significant, all the maxillary and mandibular third molars were seen earlier in girls than boys.Conclusion: It was found that the maxillary third molars on the right side developed earlier than mandibular third molars.Öğe A rare case of an immature incisor with horizontal root fracture traumatized at the time of eruption(2018) Almaz, Merve Erkmen; Sönmez, Işıl; Oba, Aylin AkbayDental trauma resulting in root fracture is a rare condition that affects up to 7% of permanent teeth, and injury to immature teeth is even rarer. This case report aimed to show the prognosis of a horizontal root-fractured immature maxillary incisor traumatized at the time of eruption. Because of an accident, a 6-year-old boy was referred to our clinic with horizontal root fracture of the permanent maxillary left central incisor associated with an extrusive luxation. The coronal segment was repositioned, and a dental splint was applied for 7 weeks. After 48 months, clinical examination revealed a positive response to electrical pulp testing and an absence color change of the tooth. Continuation of root development and calcification of the coronal pulp space was observed radiographically. It was concluded that fixation of teeth is a conservative treatment for immature teeth with horizontal root fractures, resulting in the pulp vitality and spontaneous healing with no other treatment.
