Öğe Türü:Öğe, How parenthood shapes well-being: The roles of stress coping and psychological flexibility in married couples(SAGE Publications, 2026) Ok, Zeynep; Çelik Örnek, Dilaram BillurThis study explores how parenthood affects subjective wellbeing, dyadic stress coping, and psychological flexibility in married individuals. Utilizing a quantitative, correlational design, the study sampled 402 married adults—222 with children and 180 without. Participants completed validated measures assessing dyadic coping, psychological flexibility, and relationship-specific subjective wellbeing. Data were analyzed using SPSS (version 26) and the PROCESS macro (Model 4). Findings revealed that individuals without children reported higher levels of dyadic coping and subjective wellbeing compared to parents. However, parents exhibited significantly higher overall psychological flexibility and greater alignment with value-based behavior. Analysis by number of children indicated that those with one child showed higher psychological flexibility in the present moment and in acting according to personal values than those with more children. Mediation analyses revealed that psychological flexibility partially mediated the relationship between dyadic coping and subjective wellbeing among parents, but not among non-parents. These findings suggest that while parenting introduces stress that can challenge couple dynamics, it may also foster greater psychological flexibility, which in turn can buffer the negative effects of stress on relational wellbeing.Öğe Türü:Öğe, The impact of organic and psychological pain beliefs on pain, disability, kinesiophobia, catastrophizing, and pain knowledge in shoulder pain: A cross-sectional study(Elsevier, 2026) Aksan Sadıkoğlu, Büşra; Analay Akbaba, Yıldız; Güven, Mehmet FatihPurpose: The purpose of this research is to examine the effects of organic pain beliefs (OPB) and psycho- logical pain beliefs (PPB) on pain intensity, disability, kinesiophobia, catastrophizing, and pain knowledge in chronic shoulder pain. Design: Cross-sectional observational study. Methods: In this cross-sectional study, 109 patients (66 females, 43 males; mean age 49.8 ± 10.4 years) with chronic rotator cuff–related shoulder pain were recruited using a convenience sampling method and completed the Pain Beliefs Questionnaire (PBQ), the Numeric Pain Rating Scale (NPRS), the Shoulder Pain and Disability Index (SPADI), the Tampa Scale for Kinesiophobia (TSK), the Pain Catastrophizing Scale (PCS), and the Revised Pain Neurophysiology Questionnaire (Revised-NPQ). Pearson correlation and mul- tiple linear regression analyses were used to assess the relationships of OPB and PPB with the outcome measures. Results: OPB were significantly positively correlated with activity-related pain (r = 0.30, p = .001), dis- ability (SPADI total; r = 0.21, p = .025), kinesiophobia (TSK; r = 0.42, p < .001), and catastrophizing (PCS; r = 0.40, p < .001), and were negatively correlated with Revised-NPQ (r = –0.34, p = .001). In multiple re- gression models, OPB significantly predicted greater disability ( β= 0.25, p = .013), kinesiophobia ( β= 0.45, p < .001), and catastrophizing ( β= 0.44, p < .001), explaining 4.8%-17.4% of variance in these outcomes (adjusted R ²= 0.048-0.174). Conclusions: In chronic shoulder pain, OPB show weak to moderate associations with adverse clinical outcomes and a negative association with pain knowledge, whereas PPB are not significantly related to outcomes. These findings support the potential value of targeting maladaptive beliefs and improving pain knowledge within rehabilitation. Clinical implications: Evaluating OPB and PPB in relation to pain-related parameters, kinesiophobia, and catastrophizing may help identify at-risk patients and support individualized rehabilitation and targeted education in chronic shoulder pain.Öğe Türü:Öğe, Anksiyete düzeyi ile Akdeniz diyetine uyum ve gastrointestinal semptomlar arasındaki ilişki: Kesitsel bir analiz(İstanbul Kent Üniversitesi, 2026) Topal, GülnihalAnksiyete bozuklukları, yüksek prevalansı ve bireylerin yaşam kalitesi üzerindeki olumsuz etkileri nedeniyle önemli bir halk sağlığı sorunudur. Literatürde, anksiyetenin bireylerin beslenme alışkanlıkları ve gastrointestinal semptomlarla yakından ilişkili olduğu; yüksek anksiyete düzeylerinin Akdeniz diyetine düşük uyumla ve gastrointestinal semptomlarda artışla bağlantılı olduğu vurgulanmaktadır. Bu çalışma, yetişkin bireylerde anksiyete düzeyi, Akdeniz diyetine uyum ve gastrointestinal semptomlar arasındaki ilişkiyi incelemeyi amaçlamaktadır. Bu çalışma, kesitsel araştırma deseni ile yürütülmüş olup 18–65 yaş aralığında gönüllü olarak katılan 517 yetişkin bireyden oluşan örneklem üzerinde gerçekleştirilmiştir. Veriler, sosyodemografik özelliklerin yanı sıra Beck Anksiyete Ölçeği (BAÖ), Akdeniz Diyetine Bağlılık Ölçeği (MEDAS) ve Gastrointestinal Semptom Derecelendirme Ölçeği (GSDÖ) kullanılarak toplanmıştır. Anketler, çevrim içi anket uygulama araçları ile uygulanmıştır. Çalışmaya %59,2’si kadın, %40,8’i erkek olmak üzere toplam 517 kişi katılmıştır. Katılımcıların, MEDAS ortalaması 5,6±0,45, BAÖ ortalaması 8,8±1,54, GSDÖ ortalaması 12,2±2,68 olarak hesaplanmıştır. Pearson korelasyon analizlerinde, MEDAS skorunun anksiyete (p>0,05) ve toplam GSDÖ puanı (p>0,05) ile anlamlı bir ilişki göstermediğini ortaya konulmuştur. Anksiyete skorunun GSDÖ toplam puanı ile orta düzeyde ve pozitif yönde anlamlı bir ilişki gösterdiği belirlenmiştir (p<0,001). Ayrıca, anksiyete düzeyi, GSDÖ’nün alt başlıkları ile de pozitif ve istatistiksel olarak anlamlı ilişkiler göstermiştir (p<0,001). Bu çalışmada, anksiyete ile Akdeniz diyetine uyum arasında anlamlı bir ilişki saptanmaması, literatürde bu iki değişken arasında ilişki bildiren birçok çalışmayla farklılık göstermektedir; buna karşın anksiyete düzeylerinin gastrointestinal semptomlarla anlamlı biçimde ilişkili bulunması, önceki araştırma bulgularıyla uyumlu sonuçlar ortaya koymaktadır. Bu sonuçlar, anksiyetenin gastrointestinal semptomlarla yakın ilişki içinde olduğunu, Akdeniz diyetine uyumun ise bu semptomların hafifletilmesinde koruyucu bir rol oynayabileceğini göstermektedir. Bu doğrultuda, beslenme alışkanlıklarını ve psikolojik iyi oluşu birlikte ele alan bütüncül müdahale programlarının geliştirilmesi ve etkinliğinin ileri çalışmalarda değerlendirilmesi önerilmektedir.Öğe Türü:Öğe, Evaluation of the bond strength of heat-polymerized and auto-polymerized silicone-based soft lining materials to injection-molded, milled, and 3D-printed denture base resins(Elsevier, 2027) Gedikli, Çağla Nur; Bilgin, TayfunAlthough modern dentistry aims to preserve natural teeth, the in crease in life expectancy and the elderly population means that tooth loss will likely occur in the future [1]. Implant-supported complete dentures have been reported as a more effective treatment option for edentulous patients [2,3]. However, complete dentures remain effective due to anatomical, physiological, and financial constraints [4]. Since the first use of complete dentures, the aim has been to reduce errors during the production process and improve the base materials' properties [5]. Polymethyl methacrylate (PMMA) is today's most widely used denture base material due to its many positive properties, such as biocompati bility, ease of processing, low cost, and low water solubility [6,7]. Denture bases can be fabricated conventionally using compression or injection molding techniques or digitally using subtractive or additive manufacturing techniques [8,9]. The introduction and development of computer-aided technology in the production of complete dentures is expected to overcome the diffi culties in traditional complete denture production methods and facili tate the production process [10–12]. Studies have shown that digital complete dentures offer several advantages over conventionally manu factured complete dentures, such as high hydrophilicity, less residual monomer, less microporosity, high color stability, and high adaptability due to the absence of polymerization shrinkage [13–22]. Digital com plete dentures offer significant advantages for clinicians and patients, including reduced clinical appointment time and fewer visits [23,24]. Conventional methods for producing dentures typically require at least five appointments, whereas digital methods can be achieved in just two or three visits, depending on the system used [25]. Digital systems can produce a new prosthesis using archived data without needing clinic appointments in case of a broken or lost prosthesis.Öğe Türü:Öğe, Association between dental development and midpalatal suture maturation in growing patients: A CBCT-based study(Springer Nature, 2026) Şavkan, İpek; Altundal, Gizem; Yüce, Fatma; Çöl, Nazmiye CerenThis study aimed to investigate the relationship between midpalatal suture maturation and maxillary and mandibular first and second molar development in growing patients and to determine whether any observed association persisted after accounting for chronological age and sex. Cone-beam computed tomography records of 90 growing patients were retro spectively evaluated. Midpalatal suture maturation was classified using the Angelieri method, and molar development was assessed according to the Nolla classification. Associations were evaluated using Spearman rank correlation analysis in the total sample and separately by sex. Ordinal logistic regression was used as the main regression analysis, and binary logistic regression was additionally performed after grouping the stages as non-advanced and advanced maturation. First molars showed almost complete root development from Angelieri Stage B onward, whereas second molars demonstrated a more gradual increase across advancing sutural maturation stages. Mean Nolla values for second molars increased from approximately 6.4–8.0 in Stages A–B to 9.0 or above in Stages D–E. Significant positive correlations were found between midpalatal suture maturation and all evaluated molars, with the strongest correlation observed for the mandibular second molar, followed by the maxillary second molar. In regression analyses, molar development was associated with sutural maturation in unadjusted models; however, after adjustment for chronological age and sex, none of the molar-related associations remained statistically significant following correction for multiple comparisons. Chronological age remained the dominant factor associated with MPS maturation. Molar development, particularly second molar maturation, may reflect the overall maturational trajectory but showed limited independent predictive value and should not be used alone to estimate the morphological status of the midpalatal suture.
