Introduction: In recent years, CBCT imaging has found many applications in dentistry due to its advantages such as 3D images, ease of imaging and the possibility of data reconstruction. The aim of ...this study was to evaluate the knowledge and attitude of dental residents and students of Shahid Sadoughi University of Medical Sciences towards the need to prescribe CBCT in 2022-2023.
Methods: the current study is a cross-sectional and descriptive study.146 general dentistry students and 24 dental residents participated in this study. 23 questions in the field of knowledge and attitude about the use of CBCT were used. The validity of the questionnaire was confirmed by using sources, valid scientific articles and by presenting and consulting radiology specialists. To determine the reliability, retest and Cronbach's alpha coefficient was used. Finally, the results were statistically analyzed by SPSS software version16 using chi-square, t-test and correlation tests.
Results: The level of knowledge and attitude of general students was higher than dental residents. Moreover, there was a significant difference between the level of knowledge and attitude of students with their duration of study at the university, so the higher the academic year, the lower the knowledge and attitude.
Conclusion: The results of the present study showed that dental students of Shahid Sadoughi University of Medical Sciences have a relatively moderate knowledge and attitude about the use of CBCT.
Introduction: Medical consultation plays an important role in the diagnosis and planning of dental treatment and is recommended for the patients with unclear medical histories and underlying ...diseases.
Methods: In this descriptive-cross-sectional study, 146 consultation letters of patients referred to Shahid Sadoughi Faculty of Dentistry, Yazd, Iran who were selected by easy sampling method, were investigated. In this study, SPSS version 16 statistical software was used to check the obtained data. Percentage, frequency, mean, variance and frequency distribution were used to describe the data, and X^2 (chi-square) and ANOVA tests were used for analysis.
Results: The mean age of the participants in the study was 44.71 ± 15.70 with a range of age changes from 13 to 80 year. Fifty-six patients aged 20-40 years (38.4%) and 58 patient aged 60-40 years (39.7%) had the largest number. Out of 146 patients who received medical consultation, 54 were men (37%) and 92 (63%) were women. The main reasons for consulting were to evaluate the cardiovascular condition of patients (26%), neurological diseases (19.2%) and hypertension (17.1%). Moreover, the main consideration of the responding doctors was to continue the treatment process with the usual protocol (71.2%). Considering the considerable percentage of recommendations to change the usual dental protocol in patients, medical consultation seems necessary.
Conclusion: Considering the considerable percentage of recommendations to change the usual dental protocol in the patients, it seems that it is necessary to carry out medical consultation. As a result, the role of oral and maxillofacial disease specialist in controlling the patients with systemic problems becomes important and it is necessary to establish effective communication between doctors and dentists for better patient care.
This study aimed to evaluate multi-leaf collimator (MLC) positional accuracy by using an electronic portal imaging device (EPID) and radiochromic EBT3 film. Furthermore, the MLC’s positional accuracy ...at different gantry and collimator angles of a Siemens ONCOR linear accelerator (linac) was evaluated. A picket fence test was performed to evaluate the MLC’s positional accuracy at various gantry and collimator angles of the linac. The EPID and the EBT3 films were sequentially irradiated seven times at 2-cm intervals by making a rectangular field (0.3 × 19 cm
2
). The full-width at half-maximum (FWHM) of each band (field) was calculated for all leaves by using inhouse software. Then, variations between the actual and the planned leaf locations were obtained by using the EPID and the EBT3 film at various gantry and collimator angles. The mean FWHM, acquired using the EPID and the EBT3 film ranged from 2.331 - 3.647 mm and 2.059 - 4.001 mm, respectively. Variations between the actual and the planned leaf locations were found to be affected by changes in the collimator and the gantry angles. Moreover, a -0.060 - 1.588 mm difference we seen between the result obtained from the EBT3 film and that obtained from the EPID. The mean FWHM, at most angles, for the EBT3 film was larger than that for the EPID. The findings showed average deviations for the EPID (0.001 - 0.669 mm) and EBT3 film (0.007 - 1.001 mm); these values agreed within the tolerance level (±1 mm). Furthermore, good agreement was found between the results obtained from the EPID and the EBT3 film; these two dosimetric methods can be used interchangeably, but each must be chosen considering its advantages and disadvantages.
Objective: Currently, spiritual health is the most important dimension related to adaptation in chronic diseases.The aim of the present study is review of the role of spiritual health in patients ...with type II diabetes mellitus.Improvement of spiritual health leads to better adaptation, increasing psychological well-being, decreasing mood symptoms and improvement of life quality in patients with type 2 diabetes mellitus .Therefore, it is suggested that the treatment of diabetes must include spiritual care and interventions.
Objective: The thyroid gland is susceptible to the formation of nodules. Therefore, due to the critical role of selenium in the function of the thyroid gland, the impact of this element on the size ...and volume of this organ and its nodules were examined.
Materials and Methods: During three months, two groups consisting of 30 patients with benign thyroid nodules who were referred to Baghaeipour Endocrinology Clinic were given daily doses of 100 and 200 micrograms of selenium, and a control group of 30 people without selenium consumption were assessed.
Results: The results of intergroup analysis detected that the mean (±SD) of nodules length in the 100 µg selenium consumer group was 17.13 (±7.9) and 14.93 (±6.01) before and after intervention respectively (P= 0.008). About the nodules height in the 200 µg selenium consumer group, the mean (±SD) was 9.3 (±2.8) and 8.93 (±2.71) before and after intervention in that order (P= 0.001).
Conclusion: Our findings suggest that selenium has been effective in the size and volume of the nodule and thyroid gland, as well as the TSH hormone, and further studies are needed to determine its therapeutic approach and efficacy.
Background: Diabetes mellitus is a chronic disease which affects all aspects of human life. Medical herbs have become increasingly popular as complementary therapeutic measures for patients with ...diabetes. Thus, the present research aims to explore the consumption of medical herbs in patients with diabetes in Eastern Mediterranean Regional Office (EMRO) countries through a meta-analysis. Methods: The following keywords were searched: medicine, medicinal plants, healing plants, medicinal herbs, use, usage, frequency of use, prevalence, diabetes patients, type 2 diabetes, adults with diabetes, and EMRO countries. The databases searched included Scopus, PubMed, Web of Science, and Google Scholar. Results: A total of 3,542 papers were found. After omitting repeated or irrelevant papers, 70 papers were retained. An analysis of the abstract and full text of papers led to the retention of 35 papers. A great variance was found regarding the rate of consuming medical herbs in the papers (16.8-97.7%). The relative frequency of consuming medical herbs was 38% (95% CI: 33-44). Moreover, the most prevalent herbs were fenugreek (19%), cinnamon (18%), black seed (14%), white lupinus (13%), and olive (13%) with a 95% confidence interval. About 70% of patients (95%CI: 62-79) did not inform their physician of their herbal medicine consumption. Conclusion: In light of the present findings, it can be concluded that patients with diabetes use a wide range of medical herbs. Thus, health specialists and physicians need to be aware of the possible synergic or moderating effect of herbal medicine on the therapeutic measures taken for diabetes.
Background: Legg-Calvé-Perthes Disease (LCPD), a juvenile hip disorder, is caused by impaired blood flow to the femoral head. In severe LCPD cases, the femoral head may develop a flattening ...deformity. Furthermore, if LCPD is diagnosed at the later stages, it causes early osteoarthritis of the hip. The etiology of LCPD is complex and embraces both genetic and epigenetic factors. Objectives: This review attempts to summarize the current knowledge on the role of these genetic variants in the incidence of LCPD. Methods: We searched for articles published in English using the special related search terms. Results: The genetic causes of this disease include mutations in the genes of thrombophilia factors, such as FV Leiden and anticardiolipin antibodies. The mutations of COL2A1, TRPS1, eNOS genes are the other causes. Moreover, the clinical symptoms of avascular necrosis may be indiscernible in patients with Gaucher’s disease or LCPD, and the differential diagnosis is a challenge. Conclusions: The results indicated that genetic testing may be useful in diagnosing and managing patients with juvenile hip disorders.
Introduction: Canalis Sinuosus (CS) is a bony canal in the upper jaw. This canal has branches towards the anterior ridge and the teeth, which can be exposed to damage during dental procedures such ...as implants, resulting in paranesthesia. The purpose of this study was to determine the frequency of CS in the anterior region of the maxilla by CBCT radiography in a private radiology center in Yazd City in the last 2 years, to familiarize dentists with this anatomical variety and prevent complications.
Methods: In this cross-sectional study, 218 CBCT images were selected. Images are related to the patients in the age range of 24 to 80 years. Axial, coronal and sagittal sections are reconstructed by an oral and maxillofacial radiologist. The images reviewed by two radiologists. Then, age, sex, frequency, location of the canal ending, bilateral or unilateral, sub-branches and the location of the canal in the vertical and anteroposterior dimension were checked. The results were investigated by SPSS version 16 software with Chi squared and T-test statistical tests.
Results: The reviewed images belonged to 112 (51.4%) women and 106 (48.6%) men. The frequency of CS was 96.3%. The most frequency was found in women in the age of 24-44 years (62.8%). The 95.4% was reported bilaterally. In the examination of the Accessory canals, they were not seen in 141 people (64.7%). The accessory canal (AC) was reported more frequent between central and lateral incisor. In this study, using the Chi-Square test, there was no statistically significant relationship between the presence of CS and age (P=0.188) and gender (P=0.162).
Conclusion: Due to the high frequency of CS and its branches in the anterior region of the maxilla, in order to avoid unwanted consequences during surgery, the desired area should be examined.
Introduction: Early treatment of dental anomalies and oral/dental lesions can prevent maxillofacial abnormalities and other complications. Since in most cases these lesions are asymptomatic, they are ...often discovered randomly in different radiographic images. Therefore, the aim of this study was to investigate the incidental findings on digital panoramic radiographs of referrals to Maxillofacial Radiology Department of Yazd Dental School.
Methods: In this descriptive cross-sectional study, 1949 panoramic radiographs of patients referred to the Department of Maxillofacial Radiology of Yazd Dental School in Apr 2019_ Apr 2020 were studied. Age, gender, type of lesion / anomaly, position and jaw involved were recorded in the study information form. Data analysis was performed via SPSS16 statistical software and Chi-square test.
Results: A total of 2915 lesions / anomalies were diagnosed. The frequency of these lesions / anomalies was higher in men (57.5%), middle-aged people (48.6%), mandible (69.3%) and left side of the jaws (76.8%). There was a statistically significant difference in the presence of lesion / anomaly in terms of age, sex, side and jaw involved (P-value = 0.0001).
Conclusion: Considering the frequency of random findings in panoramic radiographs, it seems that this radiography is useful for detecting many lesions and dental anomalies in the initial examination of patients. It is recommended that dentists examine the radiographs more carefully.
