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. \u0000Methodology: 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. \u0000Case 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. \u0000Case 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. \u0000Conclusion: 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. \u0000  \u0000How to cite this article: Şahin M, Toptancı İR.

This study was aimed to examine the changes in the friction coefficients and corrosion resistance of the modified Ni-Ti arch wires. \u0000Methodology: 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. \u0000Results: 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). \u0000Conclusion: 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 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. \u0000Results: 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). \u0000Conclusion: 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.

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.

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. \u0000Results: 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.

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. \u0000Methodology: 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. \u0000Conclusion: 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. \u0000  \u0000How to cite this article: Şen SC, Saygun NI, Or Koca A, Özcan E.

Although the addition of antimicrobial agents to resin composites reduces their physical properties, this is not a clinically unacceptable limit. \u0000Conclusion: NZS exhibits better mechanical properties than does BAG, but both materials can be used safely in restorative materials. \u0000  \u0000How to cite this article: Tunçdemir MT, Demirel MG.
