Aim: Traumatic dental injuries at the anterior region of the maxilla occur frequently in children and adults. In this case report, we aimed to describe the temporary aesthetic restoration of the upper lateral incisor with a fiber-reinforced bridge by using the original tooth crown, which had avulsed after dental trauma. Methodology: Case 1: A 14-year-old girl with an avulsion in tooth #11 due to trauma visited our clinic. During the examination, it was seen that the wound had healed, and there was no luxation in teeth #21 and #12. Since the patient could not undergo prosthetic procedures, for reasons including implants, and did not want a removable prosthesis, a single crown supported by acrylic tooth fibers was constructed. Case 2: A 17-year-old male patient was referred to our clinic because of an avulsed left lateral incisor tooth, which was traumatized 15 days before visiting the clinic. His medical history revealed that his parents had found the tooth two hours after the trauma. However, the emergency clinic that he had previously visited did reimplant that tooth and repaired it with fiber-reinforced composite. Case 3: In the examination of a 12-year-old male patient who applied to our clinic due to trauma, it was observed that tooth #11 had an avulsion and tooth #12 had a crown fracture. Root canal treatment was performed. A crown was made for the patient by supporting the fiber inside the canals of tooth #11 and tooth #21. It was revised aesthetically with the support of the crown of the other tooth. Conclusion: Avulsion after anterior trauma affects patients’ appearance aesthetically; thus, patients want to be treated as soon as possible. Function, phonation, and aesthetics must be quickly provided for a loose anterior tooth. Fiber-reinforced adhesive bridge techniques may be considered as a temporary treatment for providing an aesthetically appealing appearance until the completion of permanent prosthetic treatment.

目的:上颌前区创伤性牙损伤在儿童和成人中是常见的。在这个病例报告中，我们的目的是描述用纤维增强桥修复上侧切牙，使用原牙冠，在牙齿创伤后撕脱。方法:病例1:一名14岁女孩因创伤导致11号牙齿撕脱。检查时发现伤口已经愈合，21号和12号牙没有脱臼。由于包括种植在内的原因，患者无法接受修复手术，并且不想要可移动的修复体，因此构建了由丙烯酸牙纤维支撑的单个冠。病例2:一名17岁男性患者因左侧侧门牙撕脱而就诊，就诊前15天出现创伤。他的病史显示，他的父母在受伤两小时后发现了这颗牙齿。然而，他之前去过的急诊诊所确实重新种植了那颗牙齿，并用纤维增强复合材料修复了它。病例3:一名因外伤到我诊所就诊的12岁男性患者，检查发现11号牙撕脱，12号牙冠骨折。进行根管治疗。通过支持11号和21号牙齿管内的纤维，为患者制作了一个冠。在另一颗牙齿的牙冠的支持下进行了美观的修改。结论:前路外伤后撕脱伤影响患者外观美观;因此，患者希望尽快得到治疗。对于松动的前牙，必须迅速提供功能、发音和美观。纤维增强粘接桥技术可以被认为是一种临时治疗，以提供美观的外观，直到完成永久性假体治疗。如何引用本文:Şahin M, toptancyİR。临时粘接桥修复创伤缺失前牙3例报告。国际医学杂志，2021;11(增刊1):285-91。https://doi.org/10.5577/intdentres.2021.vol11.suppl1.42语言修改:本手稿中的英语已由至少两名专业编辑检查，他们都是英语母语者。

Aim: Materials used in orthodontic treatment can cause corrosion and metal ion release to the mouth. This study was aimed to examine the changes in the friction coefficients and corrosion resistance of the modified Ni-Ti arch wires. Methodology: Our sample consisted of 16 Ni-Ti arch wires (0.016 × 0.022 inches). Coating bathes involving Ni-Ti, Ni-Ti-Mo, and Ni-Ti-Cr were prepared for arch wires coating. New surfaces were analyzed by SEM, and the crystallographic structure was determined by X-rays. The friction coefficient of the coated wires was determined by nanoindentation. Artificial saliva was prepared as a corrosive condition. Impedance measurements were performed with an electrochemical analyzer. The AC impedance spectroscopy measurements were performed after four hours, seven, 15, 30, 45, and 60 days. Results: All groups were more resistant than the control group (-447 mV) [group 1 (-388 mV), group 2 (-328 mV), group 3 (-327 mV), group 4 (-427 mV), group 5 (-395 mV), group 6 (-366 mV), and group 7 (-380 mV)]. Friction coefficients of group 5 (0.252) and group 6 (0.265) were observed to be lower than those of the control group (0.288). Conclusion: In the results of our study, it was shown that the surface properties of Ni-Ti wires could be electrochemically improved. The coated wires (group 5 and group 6) had a remarkable corrosion resistance and reduced friction. The protocols that we used should help provide better-quality surfaces.

Aim: The purpose of this study is to determine the levels of dental anxiety in patients who applied to the Necmettin Erbakan University Faculty of Dentistry during the COVID-19 outbreak and to evaluate the relationships of their anxiety levels to age, gender, education level, and the frequency of visits to dentists. Methodology: There were 320 participants, including 163 females (50.9%) and 157 males (49.1%), aged from 18 to 65 years or older, who had applied to the Necmettin Erbakan University Faculty of Dentistry. The Corah Dental Anxiety Scale (CDAS) was used to determine the levels of dental anxiety (non-anxiety, little anxiety, anxiety, over anxiety, and excessive anxiety) and the anxiety groups (low or high). Descriptive statistics were presented in percentages. Data were analyzed using t-tests and one-way ANOVA and chi-square tests, at a significance level of p = 0.05. Results: Among the participants, 38.1% were at the non-anxiety level, 44.1% had very little anxiety, 10.9% had anxiety, 5% had over anxiety, and 1.9% had excessive anxiety. With regard to the anxiety groups, 82.5% were in the low anxiety group, and 17.5% were in the high anxiety group. Age, education level, and frequency of visiting the dentist were not found to have any effects on dental anxiety (p > 0.05). However, the effect of gender with regard to dental anxiety was significant (p < 0.05), as females had higher dental anxiety levels than males. Conclusion: While the effect of gender was found to be important in terms of dental anxiety, age, educational status, and the frequency of visiting the dentist did not have significant effects on dental anxiety. Females had higher dental anxiety scores and levels than males. How to cite this article: Tunçdemir AR, Büyükerkmen EB, Savaş A.

Aim: The aim of this study is to evaluate the effects of whitening toothpaste applications on the color stability of different tooth-colored restorative materials (Fuji IX, GC Fuji II LC, Equia Forte, and Kerr Point 4) Methodology: Standardized fourty disc-shaped specimens were prepared from esthetic restorative materials and polished. The baseline color values of each specimen were then measured using a spectrophotometer, according to the Commission Internationale de l'Eclairage L*, a*, and b* (CIELAB) color scale. Ten specimens from each group were then immersed in two different beverages (cherry juice and coke) for seven days. After immersion, the color value of each specimen was re-measured. Each sample was brushed with whitening toothpaste for 30 seconds using an electric toothbrush. The samples were kept in distilled water at room temperature and brushing continued twice a day for seven days. The color change value, Delta E (ΔE), was calculated. Data were analyzed by two-way ANOVA and post hoc Tukey's test. Results: When the results were evaluated, after the colored samples had been brushed with whitening toothpaste, a difference was found between the Delta E values according to the materials used (p<0.001), but no difference was found in relation to the beverages (p>0.001). When the values of the color changes were evaluated after the first brushing with whitening toothpaste and before the specimens were colored with drinks, a difference was observed in the Fuji II cola, Fuji II cherry, and Equia Forte cola groups (p<0.05). When the values of the color changes were evaluated for specimens in which brushing had been done twice a day for seven days with whitening toothpaste and before they were colored with drinks, a significant difference was observed in the Fuji II cherry and Equia Forte cola groups (p<0.05). Conclusion: Using Signal White Now whitening toothpaste for 2 min 2 times a day for seven days caused significant changes in the color of the restorative materials. The color change is dependent upon the type of restorative material that is used. How to cite this article: Kahvecioğlu F, Çoban E, Ülker HE.

Aim: In recent years, tooth-colored, dual-cure, bulk-fill composite resins, which have attracted attention for their ease of use, constitute one of the latest developments in pediatric dentistry applications. This study aimed to evaluate the color stability and surface roughness properties of three different dual-cure, bulk-fill materials and one light-cure, bulk-fill composite material used in pediatric dentistry. Methodology: In this study, three different dual-cure, bulk-fill composites (Fill-Up, HyperFIL, Cention-N) and one light-polymerized bulk-fill composite (Reveal HD) were used. A total of 70 samples were obtained for surface roughness testing. The surface roughness testing was performed with a Hysitron TI 950 Triboindenter device. A total of 105 samples were obtained for the evaluation of color stability. Cherry juice, iced tea, and distilled water were used as solutions. Initial and final color measurements were made using a spectrophotometer. The color differences between measurements were recorded according to the CIEDE 2000 system. Results: The least surface roughness among the composite groups was observed in the light polymerized Cention-N composite samples in the experimental group. In the Fill-Up and Cention-N composite groups in the experimental group, the surface roughness of the samples left to self-polymerization and the samples polymerized with light showed a statistically significant difference (p < 0.05). Among the composite groups, the highest amount of coloring was observed in the Fill-Up composite samples, which were left to self-polymerization and kept in cherry juice in the experimental group. The least coloration among the composite groups was observed in the Cention-N composite samples polymerized with light and kept in distilled water. Conclusion: Based on this information, a decrease in surface roughness and an increase in color stability can be expected due to self-polymerization and the light polymerization of dual-cured, bulk-fill composites.

This study aimed to evaluate the color stability and surface roughness properties of three different dual-cure, bulk-fill materials and one light-cure, bulk-fill composite material used in pediatric dentistry. \u0000Methodology: In this study, three different dual-cure, bulk-fill composites (Fill-Up, HyperFIL, Cention-N) and one light-polymerized bulk-fill composite (Reveal HD) were used. A total of 70 samples were obtained for surface roughness testing. The surface roughness testing was performed with a Hysitron TI 950 Triboindenter device. A total of 105 samples were obtained for the evaluation of color stability. Cherry juice, iced tea, and distilled water were used as solutions. Initial and final color measurements were made using a spectrophotometer. The color differences between measurements were recorded according to the CIEDE 2000 system. \u0000Results: The least surface roughness among the composite groups was observed in the light polymerized Cention-N composite samples in the experimental group. In the Fill-Up and Cention-N composite groups in the experimental group, the surface roughness of the samples left to self-polymerization and the samples polymerized with light showed a statistically significant difference (p < 0.05). Among the composite groups, the highest amount of coloring was observed in the Fill-Up composite samples, which were left to self-polymerization and kept in cherry juice in the experimental group. The least coloration among the composite groups was observed in the Cention-N composite samples polymerized with light and kept in distilled water. \u0000Conclusion: Based on this information, a decrease in surface roughness and an increase in color stability can be expected due to self-polymerization and the light polymerization of dual-cured, bulk-fill composites. \u0000 \u0000How to cite this article: Şivgan Güner Z, Bolgül B, İnandı T.

Aim: This study aimed to compare ethylenediaminetetraacetic acid (EDTA), phytic acid, and citric acid as chelation agents in final irrigation procedures on teeth with apical impermeability. Methodology: We used 66 mandibular premolar teeth with a single root and single canal extracted for periodontal or orthodontic reasons. All teeth crowns were removed to achieve a 14-mm root length. Mechanical preparation of the root canal was completed with a Reciproc R25 (VDW, Munich, Germany) file system. Teeth were randomly separated into three groups: Group 1: 5 ml 17% EDTA, Group 2: 5 ml 1% phytic acid, and Group 3: 5 ml 20% citric acid. We used 6 ml 5.25% sodium hypochlorite (NaOCl) in the mechanical preparation of all groups. Three teeth were selected for both the positive and negative control groups. All teeth in the experimental groups were filled by the lateral condensation method using AH Plus canal sealer and gutta-percha. For hardening of the canal sealer, samples were kept at 37 oC and at 100% humidity in a drying oven for 7 days. Later, following removal from the drying oven, two layers of nail polish were used to cover all but the apical 2 mm of each tooth. The teeth were then kept in 2% methylene blue solution at 37 oC for 7 days. The root was divided by cutting in the buccolingual direction and gutta-percha was removed. The dye leakage was measured linearly in millimeters (mm) under a stereomicroscope. Results: As a result of the apical leakage assessment, the lowest apical leakage is observed in the phytic acid group. There was a statistically significant difference between the phytic acid group and citric acid group. There was no statistically significant difference between other groups. Conclusion: While phytic acid showed similar results with EDTA on apical impermeability, it was more effective than citric acid. How to cite this article: Akın Tartuk G, Kaya S, Adıgüzel Ö.

Aim: In advanced atrophy of the posterior maxilla, applied zygoma implants increase the success of the surgical procedure by reducing morbidity and procedure time. In our study, using tomographic records, a model with posterior atrophy was obtained in a computer environment, and zygomatic and dental implants in different numbers and localizations were applied to this model. The aim of our study was to choose the most accurate surgical planning according to the stresses arising from the applied forces. Methodology: In our study, one zygoma implant on the right and left in Group 1, two zygoma implants in Group 2, one zygoma implant in Group 3 and one dental implant in the first premolar tooth area, one zygoma implant in Group 4 and one dental implant in the lateral tooth area and one zygoma implant in Group 5 and one dental implant in the lateral and a first premolar tooth area were applied. 150 N were applied vertically to the prosthetic superstructure from the lateral tooth, 1st premolar tooth, 1st molar tooth and 2nd molar tooth. As a result of the applied forces, the maximum stress values in the maxilla molar region were examined by finite element stress analysis. Results: In our study, it was observed that Group 1 had the highest stress value, followed by Group 3. Stress values in Groups 2, 4 and 5 were low and they were measured close to each other. Conclusion: As a result of our study, it was seen that zygomatic and dental implants applied in addition to the zygomatic implant reduce stress and the localization of dental implants affect the stress values.

Aim: Some immunological changes occurring in mothers during pregnancy increase their susceptibility to infections, including periodontal infections. Sheehan syndrome (SS) is a disease that occurs because of severe postpartum hemorrhage causing ischemic pituitary necrosis. The presence of multiple hormonal deficiencies leads to the impairment of bone microarchitecture, which can cause osteopenia and even osteoporosis. Osteoporosis and periodontitis are both chronic diseases characterized by bone loss. Moreover, recent studies have shown that there is a relationship between menopause, osteoporosis, alveolar bone resorption, and tooth loss. This case report aims to evaluate the oral and periodontal status of a patient with SS and to raise awareness about dental and periodontal problems that may occur in such patients. Methodology: A 63-year-old female patient diagnosed with SS in the endocrinology clinic was referred to the periodontology clinic with complaints of multiple tooth loss, mobility in her teeth, and gingival bleeding. In the clinical and radiographic examination of the patient, it was determined that all teeth had horizontal bone resorption; moreover, there was mobility in the mandibular anterior teeth and hemorrhage in the gums. When the patient’s laboratory results were examined, it was seen that the basal plasma levels of free triiodothyronine (T3) and thyroxine (T4), growth hormone (GH), prolactin (PRL), follicle stimulating hormone (FSH), luteinizing hormone (LH), progesterone, and total testosterone values were significantly lower, and the anterior pituitary elevation was significantly decreased in pituitary magnetic resonance (MR) imaging. Conclusion: The periodontium is the target tissue of sex and other hormones. Hormonal changes may affect the inflammatory–immune tissue responses of periodontal tissues. Many studies have shown that thyroid and sex hormones affect oral and especially periodontal tissues. The degradation of hormonal hemostasis may induce a series of pathological events in the oral environment, resulting in inflammatory changes in gingival tissues, periodontal attachment losses, and destruction of the alveolar bone. Systemic diseases that affect hormonal conditions, such as SS, must be considered in the evaluation of oral health. Medical physicians should refer their patients to the dentist for consultation when evaluating patients’ hormonal status and planning their treatment.

Aim: The aim of this case report is to present a series of anatomical variations and endodontic treatments in four two-canal mandibular premolar teeth and three rooted three-canal maxillary second premolar teeth with root canal treatment indications identified via clinical and radiographic examinations. The success of root canal treatment is achieved with a thoroughly examined root canal morphology that has been accurately determined radiographically and clinically before adequate shaping, irrigation, and hermetic filling procedures. Root canals that are not found or not adequately disinfected can cause root canal treatment failure and complications, such as pain, swelling, or persistent fistula, also known as flare-up, after treatment. Canal variations in the teeth were detected via periapical radiographs during the root canal instrumentation stage. Methodology: The endodontic treatments of four two-canal mandibular premolar teeth and one triple-rooted three-canal maxillary second premolar with root canal treatment indications were described. Conclusion: To achieve full success in root canal treatment, anatomical variations should be examined in detail before and during treatment, and treatment should be completed with appropriate techniques.

Aim: Secondary caries is an important problem in dental composite restoration, and nanoparticles are commonly added to the structures of resin composites to improve their antimicrobial properties. The aim of this study is to evaluate the mechanical properties of composite materials containing bioactive glass (BAG) and an experimental nano zinc-silica (NZS) complex. Methodology: An experimental resin composite containing 70 wt% filler was produced and used as a control sample. This experimental resin composite was then modified by adding different amounts of BAG (10%), NZS (10%), and both BAG and NZS (10% + 10%). NZS was synthesized in situ by milling zinc and silica to nanoscale level. Compressive strength and flexural strength were investigated using a universal testing machine. Data were analyzed using one-way ANOVA and the Tukey post-hoc test. Results: There were no statistically significant differences in compressive strength caused by the filler amount, but statistically significant changes were found in flexural strength. Although the addition of antimicrobial agents to resin composites reduces their physical properties, this is not a clinically unacceptable limit. Conclusion: NZS exhibits better mechanical properties than does BAG, but both materials can be used safely in restorative materials. How to cite this article: Tunçdemir MT, Demirel MG.
