Öğe Adaptation and testing of cognitive behavioral therapy resource of Turkish version to reduce dental anxiety in children(2022) Gürcan, Aliye Tuğçe; Tamtekin, Elif Ayşe; Aydın, Büşra; Esentürk, Gülce; Özen, BuğraAim: Dental anxiety is a common problem in pediatric dentistry and reducing it with improved communication is important. This study aimed to evaluate whether anxious children give similar answers in the dental office even though they have different cultural backgrounds and to assess the international usability of the cognitive behavioral therapy tool of the Turkish version of “Your Teeth You Are In Control” intervention including “Message to the Dentist” feedback form. Materials and Methods: Two hundred and sixty-two children aged 5-15 years attending a faculty clinic and a private dental office were included in this study. The children were asked to complete the form to report how worried they felt and the levels of pain they experienced before and after their dental treatment on a scale of 1-10 (1=the best and 10=the worst outcome). Statistical analysis was performed with IBM SPSS V23. Results: Most of the participants were worried about the needle, the dentist, and pain, respectively (38.2%, 34%, 28.2%). Most of the children raised their hand as a stop signal (94.7%). There was a statistically significant negative and weak correlation between age and anticipated pain, actual pain and anxiety scores (p=0.016, 0.003, 0.001 respectively). Conclusion: The “Message to the Dentist” feedback form and cognitive behavioral therapy resource can be used in pediatric dentistry to reduce dental anxiety in its Turkish version. It was useful to understand the sources of dental anxiety in children and this can facilitate treatment by helping pediatric dentists understand how these patients feel about dental treatment procedures and, via their efforts, to improve patient care.Öğe Case series of ectodermal dysplasia and evaluation of oral findings: A literature review(2020) Gürcan, Aliye Tuğçe; Koruyucu, Mine; Seymen, Figen; Yardımcı, SılaEctodermal dysplasia (ED) is a hereditary disease characterized by anomalies in the structures of ectodermal origin. This report aims to determine the oral features of patients with ED syndrome and to present treatment approaches. Because of nutrition, speech and aesthetical problems due to the lack of teeth 22 patients with ED syndrome referred to faculty dentistry clinic. Facial physiognomy was typical for ED and the facial height was decreased due to the vertical dimension and the delalet exfoliation of primary teeth. Also anodontia, hypodontia, delayed eruption, diffuse enamel hypoplasia, conical tooth structure, talon cusps, microdontia, and, transposition in teeth were seen in patients. In most cases, prosthesis were applied to improve the facial aesthetics, speech and oral function due to the common hypodontia. The primary goals of the dental treatment of patients with ED are enhancing aesthetics and improving masticatory function. The oral rehabilitation of the patients’ needs multidisciplinary dental treatment.Öğe Effect of surface treatments and universal adhesive application on the microshear bond strength of CAD/CAM materials(Korean Acad Prosthodontics, 2020) Şişmanoğlu, Soner; Gürcan, Aliye Tuğçe; Yıldırım-Bilmez, Zuhal; Turunç-Oğuzman, Rana; Gümüştaş, BurakPURPOSE. The aim of this study was to evaluate the microshear bond strength (mu SBS) of four computer-aided design/computer-aided manufacturing (CAD/CAM) blocks repaired with composite resin using three different surface treatment protocols. MATERIALS AND METHODS. Four different CAD/CAM blocks were used in this study: (1) flexible hybrid ceramic (FHC), (2) resin nanoceramic (RNC), (c) polymer infiltrated ceramic network (PICN) and (4) feldspar ceramic (FC). All groups were further divided into four subgroups according to surface treatment: control, hydrofluoric acid etching (HF), air-borne particle abrasion with aluminum oxide (AlO), and tribochemical silica coating (TSC). After surface treatments, silane was applied to half of the specimens. Then, a silane-containing universal adhesive was applied, and specimens were repaired with a composite, Next, mu SBS test was performed. Additional specimens were examined with a contact profilometer and scanning electron microscopy. The data were analyzed with ANOVA and Tukey tests. RESULTS. The findings revealed that silane application yielded higher mu SBS values (P<.05). All surface treatments were showed a significant increase in mu SBS values compared to the control (P<.05). For FHC and RNC, the most influential treatments were AlO and TSC (P<.05). CONCLUSION. Surface treatment is mandatory when the silane is not preferred, but the best bond strength values were obtained with the combination of surface treatment and silane application. HF provides improved bond strength when the ceramic content of material increases, whereas AlO and TSC gives improved bond strength when the composite content of material increases.Öğe Efficacy of different surface treatments and universal adhesives on the microtensile bond strength of bulk-fill composite repair(Taylor & Francis Ltd, 2020) Şişmanoğlu, Soner; Gürcan, Aliye Tuğçe; Yıldırım-Bilmez, Zuhal; Gümüştaş, BurakThe purpose of this in vitro study was to evaluate the influence of different surface treatments and aging on the microtensile bond strength (mu TBS) of bulk-fill composite resins. Bulk-fill composites (Filtek One; 3M ESPE) randomly received five different surface treatments: (1) no treatment, control, (2) 37% phosphoric acid etching (PA), (3) 9% hydrofluoric acid etching (HF), (4) air-borne particle abrasion with 50-mu m alumina particles (Al2O3), (5) tribochemical silica coating (CoJet). Following, the specimens were divided into three subgroups according to universal adhesive applied: Clearfil Universal Bond (CU; Kuraray), Prime&Bond Universal (PBU; Dentsply Sirona), or Single Bond Universal (SBU; 3M ESPE). A nanofill composite (Filtek Ultimate; 3M ESPE) was employed as a repair. Bonded specimens were stored in water for 24 h at 37 degrees C or thermal aged, then subjected to the mu TBS test. Additionally, specimens were analyzed with a contact profilometer and were evaluated with scanning electron microscopy. Control and PA treatments were showed the lowest mu TBS (p < 0.05), and there was no significant difference between these two groups (p > 0.05). Al2O3 and CoJet treatments generally exhibited a similar influence on mu TBS values. In addition, a correlation was found between surface roughness and bond strength (r = 0.831). CoJet resulted in significantly higher repair mu TBS values when compared to the other surface treatments. In addition, the use of silane-containing universal adhesive was increased the cohesive failure rate and maintained the repair mu TBS values after thermocycling.Öğe Erken çocukluk döneminde travmatik diş yaralanmalarının, maloklüzyonların ve diş çürüğünün ağız sağlığı ile ilişkili yaşam kalitesi üzerine etkisi(2021) Gürcan, Aliye Tuğçe; Koruyucu, Mine; Bayram, Merve; Seymen, FigenAmaç: Bu çalışmanın amacı, travmatik diş yaralanmalarının (TDY) ve diş çürüğünün okul öncesi çocukların Ağız Sağlığı ile İlişkili Yaşam Kalitesi (OHRQoL) üzerindeki etkisini değerlendirmektir.

Sonuç: Travmatik dental yaralanma ve maloklüzyon gözlenen dişin varlığı, okul öncesi çocukların Ağız Sağlığı ile İlişkili Yaşam Kalitesi üzerinde yalnızca çocuk alanında olumsuz bir etkiye sahiptir; ancak, diş çürüğü, hem çocuk alanında hem aile alanında Ağız Sağlığı ile İlişkili Yaşam Kalitesi ile güçlü bir ilişkiye sahiptir.Öğe Evaluation of localization of the mandibular lingula in children: A retrospective CBCT study(Elsevier Ltd, 2022) Özel, Şelale; Gürcan, Aliye TuğçeObjective: This study aimed to evaluate the anatomical localization of mandibular lingula in children aged between 6 and 18. Methods: In this study, 192 children were included. Patients were divided into three groups according to the age range as follows: aged 6 to 9, aged 9 to 13 and aged 14 to 18. cone-beam computed tomography (CBCT) was used for linear measurements. Six reference points were measured to lingula in the study: posterior, anterior and inferior aspect of the ramus, sigmoid notch, occlusal plane and distal aspect of the first molar. Results: In children aged 6–9 years, 10–13 years and 14–18 years; mean distances to the distal surface of the mandibular first molar were 23.27 mm, 28.71 mm, 36.26 mm, respectively. The lingula moved in a superior direction with age. Mean distance to the occlusal plane were 0.575 mm, 0.96 mm, 2.61 mm in patients aged 6–9 years, 10–13 years, 14–18 years; respectively. Mean distances from the sigmoid notch among children at 6–9 age, 10–13 age and 14–18 age were found to be 14.49 mm, 17.81 mm and 19.62 mm; respectively. Conclusion: Mandibular lingula was nearly the same level with occlusal plane aged between 6 and 14 (0.77 mm). In children 14–18 aged, lingula was approximately 2.61 mm above the occlusal plane. The parameters were found to be different in gender. It was found that the measurements were higher in males.Öğe Influence of application mode of universal adhesive on the surface morphology, elemental composition and bond strength of calcium silicatebased cements to composite resin: A SEM-EDX microanalysis study(Taylor&Francis, 2021) Yıldırım Bilmez, Z.; Gürcan, Aliye Tuğçe; Gümüştaş, B.; Şişmanoğlu, SonerMaintaining pulp vitality is one of the most important issues in dentistry and the quality of the bond strength of calcium silicatebased cements (CSCs) used for this purpose to restorative material directly affects the long-term success of the treatment. This in vitro study aimed to evaluate microshear bond strength (mSBS) of several CSCs to composite resin using a universal adhesive in both etch-and-rinse and self-etch modes and to examine surface characteristics after acid etching. Five CSCs, namely Angelus MTA, Biodentine, NeoMTA, TheraCal LC, and Well Root ST were evaluated. Fifteen specimens per group were used for determining the mSBS to composite resin. The composite resin was applied over CSCs using a universal adhesive either in etch-and-rinse or self-etch modes, and mSBS of CSCs to composite resin was assessed. The effect of acid etching on the surface morphology and Ca/Si ratio of CSCs were examined by SEM-EDX microanalysis. The highest mSBS was obtained for TheraCal LC in both etch-andrinse and self-etch modes. No significant difference was found between Biodentine and MTA-based cements in the etchand-rinse mode, whereas in the self-etch mode, Biodentine displayed a significantly superior bond strength. The results of SEM demonstrated distinct morphological alterations after acid etching. Acid etching decreased the Ca/Si ratio of the substrate surface by approximately 4-fold for all CSCs. TheraCal LC is more suitable for vital pulp therapy with its superior bond strength to composite resin. Furthermore, it may be suggested that adequate adhesive performance may also be achieved without an acid etching.Öğe Infuence of intracoronal bleaching agents on the bond strength of MTA cements to composite resin and their surface morphology(Springer, 2022) Şişmanoğlu, S.; Yıldırım Bilmez, Z.; Gümüştaş, B.; Taysi, M.; Berkman, M.; Gürcan, Aliye TuğçeThe objective of the present in vitro study was to evaluate micro-tensile bond strength (µSBS) of MTA cements to composite resin using a universal adhesive after internal bleaching procedure, and to examine surface characteristics of MTA cements exposed to bleaching agents. MTA specimens were divided into three subgroups according to the bleaching agent used which were, 37% carbamide peroxide (CP), 35% hydrogen peroxide (HP), and no exposure as a control group (n=12). After exposure to bleaching agent, composite resins were applied to MTA surfaces using a universal adhesive in self-etch mode. The specimens were exposed to a shear force until failure to evaluate bond strength. MTA surfaces were investigated using scanning electron microscopy (SEM) to observe the efects of the bleaching agents. Diferences between groups were analyzed using two-way ANOVA test and intergroup comparisons were assessed with Tukey test (p<0.05). Although there was a slight diference in bond strength between bleaching agents (CP and HP), no signifcant diference was found, irrespective of MTA cement. After the HP application, the bond strength values decreased approximately by half compared with the controls. SEM results demonstrated distinct morphological diferences between the intact MTA surface (control) and treated MTA surface. Distinct micro-cracks, surface irregularities, and capillary voids formed due to the superfcial dissolution caused by peroxides. Exposure to the intra-coronal bleaching agents had a negative infuence on the surface morphology of MTA cements and their bond strength to composite resin.Öğe Perception of oral and dental health awareness and assessment of dental habits in preclinical dentistry students: A questionnaire study(2022) Gürcan, Aliye Tuğçe; Mert Eren, MeltemAim: The oral and dental hygiene behaviors of patients are affected by their dentists. Although dental students attend preclinical courses in their first and second years of education, they are expected to be knowledgeable about oral and dental health due to their future position as being role models for patients. In this study, it was aimed to evaluate the oral and dental health awareness and oral health habits of preclinical dental students. Material and Methods: 127 preclinical dental students were included in this study. A questionnaire consisting of 39 questions about oral-dental health habits and knowledge levels was prepared. The results were analyzed with the SPSS 22.0 software. A p-value of smaller than 0.05 was considered statistically significant. Chi-squared and Mann-Whitney U tests were used for statistical analysis. Results: Frequency of daily tooth brushing, gingival bleeding, halitosis, toothpaste preference, satisfaction with tooth color and frequency of dental visits were found to be statistically significant. There was no significant difference between the 1st-year and 2nd-year student groups in terms of their responses to the questions (p> 0.05). A statistically significant difference was found between the male and female groups for their responses to the questions on topics such as toothpaste preference, satisfaction with the color of their teeth, frequency of dental examination, frequency of tooth cleaning and toothbrushing time (p <0.05). It was also found that the oral and dental awareness and dissatisfaction with teeth levels were higher in the female participants. Conclusion: It was observed that the 1st-year and 2nd-year participants had similar views regarding oral hygiene and attitudes since they had just started their vocational training. Awareness and knowledge levels are expected to increase with class year and as clinical courses progress.Öğe Remineralization efficiency of three different agents on artificially produced enamel lesions: A micro-CT study(2024) İlisulu, Sabiha Ceren; Gürcan, Aliye Tuğçe; Şişmanoğlu, SonerObjective: This study aimed to assess the remineralization efficacy of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), silver diamine fluoride/potassium iodide (SDF/KI), and sodium fluoride with functionalized tricalcium phosphate (NaF/fTCP) on artificial early enamel lesion using laser fluorescence and micro-CT analysis. Methodology: On extracted impacted third molars, artificial enamel lesions were prepared. Twenty-eight specimens were randomly assigned to four groups (n = 7 per group): a control group (artificial saliva), CPP-ACP (GC Tooth Mousse), SDF/KI (Riva Star), and NaF/fTCP (Clinpro White varnish). Following the manufacturer's instructions, the remineralization agents were applied to demineralized surfaces. Laser fluorescence and micro-CT were used to evaluate the remineralization efficacy of the agents and analyzes were performed during four stages: before demineralization, after demineralization, 1st day of remineralization and 30th day of remineralization. Shapiro-Wilk test, repeated measures two-way ANOVA, and Spearman correlation tests were used for statistical analysis. A significant level of p < 0.05 was established. Results: SDF/KI significantly reduced the lesion area and lesion volume on the demineralized enamel surface after 30 days of remineralization. In the T3 period, SDF/KI increased the mineral density statistically significantly compared to the T1 period. The laser fluorescence values for all three remineralizing agents exhibited a linear decrease. A significant correlation between the fluorescence values and the mineral density was found (p = 0.01). Conclusion: All three investigated agents were showed positive remineralization efficacy on artificial enamel lesion. However, SDF/KI, containing silver diamine fluoride and potassium iodide exhibited superior than other agents in promoting remineralization. Clinical significance: Although all three remineralization agents showed positive remineralization efficacy on artificial enamel lesions, SDF had higher remineralization performance over the other two agents. SDF has potential to prevent progression of demineralization in treating children with high caries risk in the long-term.
