Comparison of clinical and magnetic resonance imagining data of patients with temporomandibular disorders
(2020) Somay, E.; Yilmaz, B.; 0000-0003-0633-5648; 32134038; AAP-9684-2021
Background: There are important criteria in the diagnosis of temporomandibular disorders (TMDs). These become significant if supported by magnetic resonance imaging (MRI). Otherwise, these findings alone may not be sufficient to diagnose TMD. Aim: This study compared the relationship between clinical findings indicated by patient and physician and MRI results in the diagnosis of TMD. Materials and Methods: Clinical examinations were performed in patients suspected of TMD for pain, difficulty in mouth opening, masticatory muscle tenderness, deviation (during mouth opening), normal mouth opening, and presence of bruxism. The MRI findings of the patients were compared with the clinical examinations. Results: MRI and clinical examination data of 136 patients were examined. The results showed significant correlations between deviation, normal mouth opening, and MRI results of TMD (P < 0.05). No correlation was found between age groups and clinical findings of TMD. TMJ was determined in normal limits in 61% of MRI results. Conclusions: Except for deviation and normal mouth opening, complaints and clinical findings determined by the clinicians do not support TMD. This may be due to the subjective nature of the clinical findings, and MRI results are needed for precise results.
Evaluation of Coronavirus Disease (COVID-19) Awareness of Patients Undergoing Dental Interventions in Turkey
(2021) Yilmaz, B.; Somay, E.; 0000-0003-0633-5648; 34018986
Aims: We aimed to objectively assess the COVID-19 awareness of the patients requiring dental interventions in our dental clinic by utilizing a newly generated questionnaire, which may serve helpfully in the hard battle against the pandemic in our country. Materials and Methods: This study included 306 volunteer adults who applied to our dental clinic for dental interventions during the early days of COVID-19 outbreak in Turkey. All patients responded to a newly created questionnaire composed of four sections with 19 questions those mostly assessing the social and demographic details; like the participant's age, gender, marital status, education status, medical history, basic dental hygiene habits, occupation, and general information about the COVID-19 infection and its protection methods. Results: The outcomes of 306 participants revealed that their gender, age, and education status showed significant distinctions about the dissemination of coronavirus via dental interventions. Higher education status was linked to a loftier level of social awareness about the COVID-19 infection and its potential associations with dental interventions. It was observed that the participants were unsatisfactorily cautious against the COVID-19 infection and its dissemination pathways in their social environment, particularly in the specific case of systematic diseases and preventive measures. The primary way of obtaining information about the COVID-19 infection was the electronic websites. Conclusion: Deplorably, accentuating the urgent need for further intensive training programs on the relationship between the systemic diseases and COVID-19 infection, and explicit daily care methods in the social environment.
Role of acoustic radiation force-based elasticity imaging in endometrium pathologies
(2020) Cenkeri, H. C.; Bidaci, T. B.; Yilmaz, B.; Desteli, G.; 33047689
Backround: Ultrasonography is difficult to distinguish between endometrial pathologies and often requires curettage. ARFI (Acoustic Radiation Force-Based Elasticity Imaging) is a new ultrasonography elastography method. Using ARFI, it is possible to obtain information about the likelihood of the tissue benign or malignant. Aim: The aim of this study is to evaluate the contribution of ARFI to differentiate endometrial pathologies in hysterectomy specimens. Subjects and Methods: Our study was prospectively, January-May 2017, performed in randomly 45 cases of 41-91 years of age (mean 58.3 years) who have decided to have hysterectomy. Hysterectomy was performed for uterine prolapse and endometrial hyperplasia in elderly patients and menorrhagia in young patients. Pathology results were compared with ARFI values and endometrial thickness. ANNOVA test was used for the comparison of ARFI values. Results: Pathology revealed 14 cases of endometrial atrophy, 11 cases of proliferative phase, 10 cases of polyp, 6 cases of endometrial hyperplasia, and 4 cases of endometrium cancer. There is a statistically significant difference between mean ARFI values of endometrium, subendometrium, and myometrium of the groups (P < 0.05). There was a statistically significant difference between the mean endometrial thickness of the groups (P < 0.05). Conclusion: Endometrium ARFI contributes to the differential diagnosis of endometrial pathologies. Subendometrial and myometrial ARFI values decrease in polyps and increase in hyperplasia. Our study shows that the addition of subendometrium ARFI to gray-scale sonography before deciding on invasive procedures in endometrial pathologies may improve diagnostic accuracy. We concluded that further in vivo studies will establish the usefulness of this technique for preoperative diagnostic measures.
Survival of Root Canal-Treated Teeth Adjacent to An Implant: A Retrospective Case-Control Study
(2023) Sisli, S. N.; Gul Ates, E.; Ozcelik, T. B.; Yilmaz, B.; Revilla Leon, M.; 0000-0001-5685-4409; 0000-0002-6166-2601; 37839623; JJF-5618-2023
Objectives: To evaluate the survival of root canal treated (RCT) teeth adjacent to an implant compared with that of RCT teeth of the same patient non-adjacent to an implant.Materials and methods: RCT tooth of each patient adjacent to an implant were included in the test group. The control group consisted of another RCT tooth of the same patient; the control RCT tooth was not adjacent to an implant and selected to be of the same type of the RCT tooth in the test group. 72 teeth of 36 patients with at least 4-year follow-up were included. In addition to survival, other clinical and demographic parameters investigated were age, sex, tooth type and position, presence of a crown, presence of retreatment, presence of a post-core, presence of adjacent edentulous area, presence of implant-supported fixed prosthetic restoration on the antagonist tooth and periapical health status. Pearson Chi-Square and Fisher Exact tests were used to compare the test and the control groups with categorical variables (alpha=0.05). Survival curves were obtained by the Kaplan-Meier method, and the Log-rank test was performed to compare the survival probabilities (alpha=0.05).Results: No significant difference in survival rates was observed between the test and the control groups (p = 0.72). Similarly, no significant relationship was found between the investigated clinical variables and the survival rates of RCT teeth (p>0.05). Survival times differed depending on the presence of an adjacent edentulous area (p<0.001) and the periapical health status (p = 0.026).Conclusions: RCT teeth with unhealed periapical tissues had a shorter cumulative survival time. Similarly, those adjacent to an edentulous area had shorter cumulative and complication-free survival times.Clinical Significance: This is the first study to determine the survival outcome of a RCT tooth adjacent to an implant compared to a non-adjacent one in the same patient. Being adjacent to an implant did not have a detrimental effect on the survival time and rate of RCT teeth.
