    3b yazici sistemiyle üretilen inley restorasyonlarin siman araliklarinin değerlendirilmesi
    (2023) Yigit, Elif; Bahadir, Hasibe Sevilay; Bulut, Alican
    Bu çalışmanın hedefi, üç boyutlu (3B) yazıcı sistemi kullanılarak üretilen inley restorasyonlarının siman aralığı değerlerini araştırmaktır.Bu çalışma kapsamında, toplamda 60 adet typodont diş kullanıldı. Bu dişlerin yarısı (n=15), mesio-oklüzal (MO) kaviteler için, kalan yarısı (n=15) ise mesio-oklüzal-distal (MOD) kaviteler oluşturmak için kullanıldı. Bukkolingual genişlik 2,5-3mm ve pulpal derinlik 2mm olacak şekilde okluzal kaviteler hazırlandı. Proksimal inley kaviteler, basamak derinliği 1,5mm ve basamak kalınlığı 1 mm, bukkolingual genişliği 5 mm olarak tasarlandı. Kaviteler, intraoral dijital tarayıcı (TRIOS 3 Basic, Kopenhag, Danimarka) kullanılarak tarandı ve EXOCAD (Exocad Dental CAD 2.2, Darmstadt, Almanya) yazılımıyla inley restorasyon tasarımları yapıldı. 3B yazıcı (Phrozen sonic mini 4K SLA cihazı, Hsinchu, Tayvan) ile restorasyonların üretimi yapıldı. Restorasyonların siman aralığı değerlendirmek için silikon replika yöntemi kullanıldı ve kesitler stereomikroskop altında x10 büyütmede incelendi. Ölçümler üç farklı noktadan yapılıp, analiz için Adobe Photoshop programı kullanıldı. SPSS 22.0 programında Pairwise-Comparisons ve Kruskal-Wallis testleri ile verilerin analizi yapıldı (?

    Effect of Various Beverages on Adhesion of Repaired CAD/CAM Restorative Materials
    (Mdpi, 2023) Yigit, Elif; Gungor Erdogan, Hamiyet; Eyuboglu, Tan Firat; Ozcan, Mutlu
    (1) Background: The purpose of this study was to determine the effect of commonly consumed beverages on the bond strength of three different computer-aided design-computer-aided manufacturing (CAD/CAM) resin-ceramic hybrid materials repaired with resin-based composite (RBC) materials. (2) Materials and Methods: Rectangular prism specimens (N = 138) measuring 6 mm x 5 mm x 2 mm were obtained from GC Cerasmart (GC), Lava Ultimate (LU), and Vita Enamic (VE) blocks. These blocks were polished and then subjected to thermal cycling (10,000 cycles, 5 & DEG;C to 55 & DEG;C). After the surface treatment was applied, the average surface roughness value was measured. All the surfaces were repaired with RBC. Thermal cycling was performed for the second time. Each group was then distributed into three subgroups according to the beverage used: tea (t), cola (c), and distilled water (0) (n = 15). The specimens were stored in these solutions for 28 days and then subjected to the shear bond strength (SBS) test. Statistical analysis was performed using a two-way ANOVA test with Bonferroni adjustment. (3) Results: The surface roughness of the materials presented no significant difference after different surface treatments (p > 0.05). No significant difference was observed among the materials (p > 0.05). Tea and cola presented similar SBS values (p > 0.05). Both were significantly lower than distilled water (p < 0.001, p < 0.001, respectively). (4) Conclusions: Consumption of beverages reduces the bond strength in surfaces repaired with RBC to CAD/CAM resin-ceramic hybrid materials. (5) Clinical Significance: Repairing damaged resin matrix dental restorations with RBC is advantageous in terms of time and cost by achieving adequate bond strengths. Frequently consumed beverages reduce the bond strength of repaired CAD/CAM resin-ceramic hybrid materials.

    Evaluation of the relationship between GOHAI, MNA and the dental hygiene of using denture wearers for older patients
    (Wiley, 2023) Erdinc, Guelbahar; Yigit, Elif
    Background: The use of removable dentures increase due to tooth loss that occurs with ageing. The relationship between age, use of removable dentures and nutrition is important. Objective: To evaluate the effectiveness of the GOHAI, the MNA, and the dental hygiene of older patients using dental prostheses. Methods: This was a cross-sectional study of people over 65 who used removable prostheses in at least one jaw (partial or complete denture) for a minimum of 6 months (n = 120). The data were collected using questionnaires of a qualified examiner and oral clinical tests with interviewers in person. The subjects' nutritional status was assessed by a Turkish version of the mini nutritional assessment (MNA). GOHAI questionnaire was used to evaluate those aspects considered to have an impact on the quality of life of the older population, such as functional limitation, aesthetic dissatisfaction, chewing discomfort, avoidance of particular food, out-of-social contacts and self-medication administered for dental pain. Results: There was no statistically significant correlation between the GOHAI score and sociodemographic and intraoral data (p > .050). A negative correlation was found between age and MNA. A statistically significant difference was found between the MNA score's median values according to the participant's education level, type of prosthesis, and marital status (p < .050). Good was determined as the highest GOHAI category with 54%. Conclusion: There is a negative correlation between age and MNA. The risk of malnutrition increases with age. Since the oral condition also affects the patient's systemic condition, the team caring for geriatric patients must bring these people to the maximum level of life in a multidisciplinary manner.
