Öğe Assessment of hygiene habits and attitudes among removable partial denture wearers in a university hospital(Medknow Publications, 2015) Çakan, Umut; Yüzbaşıoğlu, Emir; Kurt, Hanefi; Kara, Haluk; Turunç, Rana; Akbulut, Aslıhan; Aydın, KaderAims: The aim of this study was conducting a survey of hygiene habits and use of removable partial dentures (RPDs) and correlate them with the social conditions of the interviewees. Methods: A total of 145 RPD wearers were interviewed by experienced clinical staff using a structured questionnaire. A Chi-squared test was performed to evaluate statistical significance between the variables, and the level of significance was P < 0.05. Results: A total of 72 (49%) patients reported that they had not been well informed by the dentists. Brushing was the most frequent cleaning method (57.6%). 77 (53.1%) patients did not take off their dentures at night. The frequency of cleaning dentures and using cleansing tablet was significantly higher in females than in males (P < 0.05). The frequency of denture cleaning, cleaned parts of denture, use of cleansing tablet, removal of dentures at night, frequency of tooth brushing, does not show any significant difference according to age, educational status or duration of denture usage (P > 0.05). RPD wearers did not clean their dentures and natural teeth satisfactorily and had limited knowledge of denture cleansing and oral hygiene maintenance. Conclusions: Hygiene habits and attitudes may be affected by gender, but education level and hygiene attitudes may not always present positive correlation. Dentists should thoroughly inform patients about the harmful effects of overnight wearing and motivate to clean metal parts of RPD's and cleansing tablet use in order to minimize the abrasive effect of widely preferred cleaning method of brushing with toothpaste.Öğe Comparison of digital and conventional impression techniques: Evaluation of patients' perception, treatment comfort, effectiveness and clinical outcomes(BioMed Central, 2014) Yüzbaşıoğlu, Emir; Kurt, Hanefi; Turunç, Rana; Bilir, HalenurBackground: The purpose of this study was to compare two impression techniques from the perspective of patient preferences and treatment comfort.Methods: Twenty-four (12 male, 12 female) subjects who had no previous experience with either conventional or digital impression participated in this study. Conventional impressions of maxillary and mandibular dental arches were taken with a polyether impression material (Impregum, 3 M ESPE), and bite registrations were made with polysiloxane bite registration material (Futar D, Kettenbach). Two weeks later, digital impressions and bite scans were performed using an intra-oral scanner (CEREC Omnicam, Sirona). Immediately after the impressions were made, the subjects' attitudes, preferences and perceptions towards impression techniques were evaluated using a standardized questionnaire. The perceived source of stress was evaluated using the State-Trait Anxiety Scale. Processing steps of the impression techniques (tray selection, working time etc.) were recorded in seconds. Statistical analyses were performed with the Wilcoxon Rank test, and p < 0.05 was considered significant.Results: There were significant differences among the groups (p < 0.05) in terms of total working time and processing steps. Patients stated that digital impressions were more comfortable than conventional techniques.Conclusions: Digital impressions resulted in a more time-efficient technique than conventional impressions. Patients preferred the digital impression technique rather than conventional techniques.Öğe Does anxiety have an impact on temporomandibular disorders? A study in a Turkish sample by using specific questionnaires(2024) Akbulut, Aslıhan; Kurt, Hanefi; Uslu Toygar, Hilal; Yıldırım, ErolObjective: The aim of the study is to verify the impact of anxiety on temporomandibular disorders (TMD) by using specific questionnaires in a Turkish sample. Methods: This survey was conducted on 292 patients with a mean age of 38.59 ± 10.38 using Helkimo index, Oral Health Impact Profile (OHIP-14), and State Trait Anxiety Inventory (STAI). Spearman Correlation and Fisher Freeman Halton analyses were used for the statistical analysis. Results: There was no statistically significant difference between the Helkimo anamnestic dysfunction (HAD) levels in terms of OHIP-14 total scores or STAI state scores. There was, however, a statistically positive correlation between STAI state and OHIP-14 total values at 18.4%, a positive correlation between the STAI trait and OHIP-14 total values at 29.8%. Conclusion: No significant correlation was observed between OHIP-14 total scores, STAI state scores, and HAD levels. Therefore, this study did not find a significant relationship between TMDs and anxiety.Öğe Effect of yoga-based exercise program in female patients with myofacial pain of temporomandibular disorders(2024) Atılgan, Esra; Kurt, Hanefi; Algun, Zeliha CandanObjectives: The study was conducted to investigate the effect of Yoga-based exercise program on pain, range of motion (ROM), quality of sleep, depression and quality of life in female patients with myofacial pain of temporomandibular disorders (TMD). Materials and methods: 39 Female patients with myofacial pain of TMD were included in the study. Yoga based exercise program was performed to the first group and second group was control group. Visual Analog Scale (VAS), Neck Pain and Disability Scale (NPDS), neck and jaw ROM, Pittsburg Sleep Quality Index (PUQI), Beck Depression Inventory (BDI) and Short Form 36 (SF36) were evaluated. Evaluations were repeated before treatment and 6 weeks later. Results: From the measurements, a decrease in Temporomandibular Joint (TMJ) (p = 0.005) and neck pain (p = 0.031) was found to be significant in favor of Yoga Group. It was also observed that the increase in ROM in the neck right lateral flexion (p = 0.001) in favor of Yoga Group. The sleep quality did not change. In yoga group, a decrease in depression level (p = 0,023) and increase Quality of life in parameters of physical function (p = 0.023), vital capacity (p = 0.026), emotional health (p = 0.002), mental health (p = 0.080) were found as significant, statistically. Conclusions: It was concluded that yoga-based exercise program can be used as an alternative program in patients with myofacial pain of TMD. Further study on myofascial pain of TMD is recommended. Clinical relevance: Yoga-based exercise program can be used in patients with myofascial pain due to TMD.Öğe Influence of stabilization splint thickness on temporomandibular disorders(Quintessence Publishing Co, Inc, 2022) Bilir, Halenur; Kurt, HanefiPurpose: To assess the effect of stabilization splint (SS) thickness on temporomandibular disorders (TMDs). Materials and Methods: Participants were selected from patients who applied to the clinic with a complaint of temporomandibular disorders (TMDs). Symptoms were evaluated with the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Regarding the treatment plan, patients were divided into two groups: the 2-mm-thick splint group (2-mm TSG) and the 4-mm-thick splint group (4-mm TSG). They used SSs at night (8 hours) and were recalled 1, 2, 3, and 6 months after splint insertion. At the end of the study, 72 patients (2-mm TSG = 39, 4-mm TSG = 33) had completed the 6-month follow-up. The SPSS program was used for statistical analysis. The results of the analysis were evaluated at a significance level of .05. Results: Pain in the muscles decreased significantly in the muscle disorders and combined groups (both 2- and 4-mm TSG) after 6 months of treatment (P < .05). In the combined group, TMJ sounds significantly decreased after 6 months of treatment, and there was a statistically significant difference between the 2-mm TSG and the 4-mm TSG (P = .045). Also, in the combined group, maximum unassisted opening (MUO) values of patients treated with 2-mm-thick splints decreased after 6 months of treatment (P = .022). Conclusion: Both 2-mm-thick and 4-mm-thick splints were effective in the treatment of muscle disorders and disc displacements, especially in muscle-related pain and TMJ sound symptoms.Öğe Oral health-related knowledge, attitudes and behaviours of elementary school teachers(MDPI AG, 2021) Yılmaz, Gülçin; Riad, Abanoub; Krsek, Martin; Kurt, Hanefi; Attia, SamehAbstract: Background: elementary schoolteachers play a central role in shaping their students’ beliefs, attitudes, and behaviours related to health and oral hygiene. This study was designed to evaluate Turkish schoolteachers’ levels of oral health knowledge, attitudes, and behaviours. Methods: A crosssectional survey-based study was conducted among elementary schoolteachers in Istanbul using a validated self-administered questionnaire. The questionnaire was composed of 36 multiple-choice items categorised into six sections, and the participants were recruited using convenience sampling. (3) Results: A total of 385 elementary schoolteachers participated in this study. The majority were female (62.2%), qualified with a licensure degree (81.3%) and working in public schools (86.5%). Female gender and greater work experience were found to be promoters for oral health knowledge and positive attitudes. The correlation between their perceived knowledge and actual knowledge was very weak, thus suggesting that the teachers are inclined to overestimate their knowledge. Conclusions: The Turkish elementary schoolteachers showed satisfactory oral health knowledge and attitudes toward oral health education. The teachers’ knowledge about dental trauma management was inadequate, necessitating urgent educational interventions, especially for physical education teachers, who are at the greatest risk of encountering such events during their work. The oral hygiene behaviours were not associated with teachers’ oral health knowledge, attitudes, or practice, thus requiring further investigation.Öğe Stabilizasyon splintinin oklüzyondaki değişikliğe etkisinin değerlendirilmesi(İstanbul Medipol Üniversitesi Sağlık Bilimleri Enstitüsü, 2021) Yılmaz, Gülçin; Kurt, HanefiBu çalışmanın amacı, iki farklı dijital oklüzal kayıt cihazı ile temporomandibular rahatsızlıkların (TMR) tedavisinde kullanılan stabilizasyon splintinin 3 aylık kullanımı sonrası oklüzyonda meydana gelen değişimin değerlendirilmesidir. TMR'ye sahip 20 gönüllü birey ve sağlıklı temporomandibular ekleme sahip 20 gönüllü bireylerden oluşmak üzere toplam 40 bireyin dahil olduğu çalışmada, tüm gönüllü bireylerin başlangıç ve oklüzal kayıtları T-SCAN ve OccluSense ile alındı. TMR'ye sahip gönüllü bireylere premolar bölgesinde 3 mm yükseltme yapılacak şekilde sert stabilizasyon splintleri yapıldı. Bu splintlerin; 7.gün, 1. ay, 2. Ay ve 3. Ay olmak üzere düzenli kontrolleri ve uyumlamaları yapıldı. 3 ayın sonunda 40 gönüllü bireyin tamamından T-SCAN ve OccluSense ile oklüzal kayıtları yeniden alınarak tedavi öncesi ve sonrası oklüzal temasları ve farklı dijital kayıt cihazları ile elde edilen sonuçlar karşılaştırıldı. Splint uygulanan ve kontrol grubunda olan hastaların tedavi öncesi ve sonrası oklüzal temasları arasında istatistiksel olarak anlamlı bir fark görülmedi. Sonuç olarak sert stabilizasyon splinti ile tedavi edilen TMR'ye sahip hastaların oklüzyonunda 3 aylık kullanım sonucu değişiklik olmadığı ve T-SCAN ile OccluSense cihazlarının ölçümlerinin uyumlu olduğu görüldü.Öğe Temporomandibular rahatsızlık semptomları üzerine splint yüksekliği etkisinin değerlendirilmesi(İstanbul Medipol Üniversitesi Sağlık Bilimleri Enstitüsü, 2015) Bilir, Halenur; Kurt, HanefiAmaç: Bu çalışmanın amacı splint yüksekliğinin temporomandibular rahatsızlıkların semptomları üzerine etkisinin değerlendirilmesidir. Materyal ve Metot: Hastalar 1,5 yıl boyunca İstanbul Medipol Üniversitesi Diş Hekimliği Fakültesi Protetik Diş Tedavisi Anabilim Dalı'na temporomandibular rahatsızlık şikayetiyle başvuran hastalar arasından seçilmiştir. Çalışmaya katılmaya gönüllü olan hastalardan bilgilendirilmiş onamları sözlü ve yazılı olarak alınmıştır. Muayenesi sonrasında splint tedavisine karar verilen hastalarda rutin olarak uygulanan splintin oklüzal yüzeyine tüm karşıt ark dişlerinin temasının sağlanması için yapılan yükseltme işlemi 52 tanesinde 2 mm, diğer 52 tanesinde ise 4 mm olarak uygulanmıştır. Altı ay sonunda her iki grupta 39 hasta olmak üzere toplam 78 hasta kontrollerine düzenli devam etmiş ve son kontrole gelmiştir. Hastalar tedavinin 1., 2. ve 3. aylarında Temporomandibular Rahatsızlıklar için Araştırma Teşhis Kriterleri'nin (TMR/ATK) anamnez ve muayene formunun sadece muayene formu ile tedavinin başlangıcı ve 6. ay sonunda ise TMR/ATK'nın anamnez ve muayene formu ile değerlendirilmiştir. Her hastaya, stabilizasyon splinti Dr. Okeson'un (1) önerdiği şekilde, kare plakların 2 mm veya 4 mm yükseltileceği şekilde üzerine otopolimerizan akrilik reçine kullanılarak hazırlanmış ve hastalardan 6 ay boyunca gece yatarken kullanmaları istenmiştir. Hastalar 1., 2., 3. ve 6. aylarda kontrole çağrılmıştır. Splintler tedavi süresince kontrollerde uyumlandırılmıştır. Bütün hastalar TME'nin anatomisi ve fonksiyonu, tıklamanın ve kilitlenmenin mekanizması, ağrının nedeni ve tedavi alternatifleri hakkında tedavi öncesi bilgilendirilmiştir. Çalışmada elde edilen bulgular değerlendirilirken, istatistiksel analizler için IBM SPSS Statistics 22 (IBM SPSS, Türkiye) programı kullanılmıştır. Sonuçlar, anlamlılık p<0,05 düzeyinde değerlendirilmiştir. Sonuçlar: Bu araştırma sonucunda 2 mm ve 4 mm splint grupları arasında tedavi sonrasında hastaların subjektif semptomlarından ağrı dereceleri açısından değerlendirildiğinde istatiksel olarak anlamlı bir fark olmasına rağmen, mandibulanın fonksiyonlarında kısıtlılık, depresyon ve somatizasyon dereceleri gibi subjektif semptomları ve TME sesleri, kaslar ve eklemlerin palpasyondaki ağrı dereceleri gibi objektif bulgularında tedavi öncesine göre düzelme olduğu, ancak iki grup arasında düzelmedeki etkinlik açısından istatistiksel olarak anlamlı fark bulunmadığı görülmüştür.Öğe Wear resistance and microhardness of various interim fixed prosthesis materials(Nihon University, 2019) Dayan, Çağatay; Kiseri, Burim; Gençel, Burç; Kurt, Hanefi; Tuncer, NecatThe aim of the present study is to evaluate the wear resistance and microhardness of various interim fixed prosthesis materials with different chemical compositions and curing methods. One heat-cured and four self-cured acrylic resins, and three self-cured, one light-cured, and one dual-cured composite-based materials were tested. For microhardness, samples from each group were tested after storing either at 37 degrees C in artificial saliva for 7 days, followed by thermocycling, or in distilled water solution at 37 degrees C for 24 h. For the evaluation of wear, the remaining samples were evaluated using a 3D scanner and a surface analysis program before loading in the chewing simulator and after every 10,000 cycles. There was a significant difference in wear behavior among the materials tested at both 10,000 and 20,000 cycles (P < 0.001). Microhardness and wear resistance were significantly different between acrylic and composite materials.
