It is believed to be a common occurrence in the patients suffering from recurrent, acute inflammatory diseases. The purpose of this study was to compare the prevalence of geographic tongue between asthmatic patients and healthy subjects. Materials and Methods: This descriptive-analytic study was conducted on 80 asthmatic patients and 80 healthy controls. The asthmatics were selected from among the patients presenting to Masih Daneshvari hospital with a confirmed diagnosis of asthma, while the healthy controls were selected from among patients' companions. The case and control subjects were matched according to age, sex and cigarette smoking status. The presence of geographic tongue was evaluated in the subjects by clinical examination and also by using a questionnaire. The data were entered into SPSS software version 22 and were evaluated using Chi-Square test. Results: The prevalence of geographic tongue was 21.2% (n=17) in the asthmatic patients and 5% (n=4) in the healthy controls. A significant association was found between asthma and occurrence of geographic tongue (P<0.002). The incidence of geographic tongue in the asthmatics was 4.2 times greater than that in the healthy individuals with a relative risk (RR) equal to 4.2 and an attributable risk (AR) of 16%. In both groups, the dorsal and lateral surfaces of the tongue were more commonly affected than the ventral surface. No significant association was found between the involvement of a specific tongue surface and asthma (P=0.748). Conclusion: According to the results, the asthmatic patients showed a significant higher prevalence of geographic tongue compared with the healthy controls.}, Keywords = {Asthma, Geographic tongue, Prevalence}, volume = {2}, Number = {1}, pages = {1-5}, publisher = {Islamic Azad University Dental Branch }, doi = {10.29252/jrdms.2.1.1}, url = {http://jrdms.dentaliau.ac.ir/article-1-146-en.html}, eprint = {http://jrdms.dentaliau.ac.ir/article-1-146-en.pdf}, journal = {Journal of Research in Dental and Maxillofacial Sciences}, issn = {}, eissn = {2383-2754}, year = {2017} } @article{ author = {Rahrotaban, S and Samani, S and Jolehar, M and Badie, F}, title = {Comparison of the Expression Intensity of Estrogen Receptor Marker in Oral and Cutaneous Pemphigus Vulgaris}, abstract ={Background and aim: Pemphigus vulgaris (PV) is an autoimmune disorder that can clinically manifest as oral mucosal ulcers. Several researchers believe that the level of female sex hormones such as estrogen and progesterone could be effective in the pathogenesis and growth of lesions such as desquamative gingivitis. Studies related to oral ulcers have revealed contradictory results regarding the presence of estrogen in the gingiva and salivary glands. Therefore, the main objective of this research was the evaluation and comparison of estrogen receptor (ER) expression in oral and cutaneous PV. Materials and Methods: In this cross-sectional study, immunohistochemical staining was performed on 40 Paraffin blocks of oral and cutaneous PV. Staining intensity was investigated. Data were analyzed by Mann-Whitney test, Fisher test and T-test using SPSS 18 software. Results: The mean age of the patients equaled 38.3±11.8 and 42.8±11.3 years in oral and cutaneous PV, respectively. The most common sites of ER expression were the buccal mucosa (55%), trunk (21.1%) and scalp (21.1%). Positive ER expression in oral and cutaneous PV was found in 35% and 89.4% of the cases, respectively. Also, there were significant differences in ER expression intensity between cutaneous and mucosal PV (P=0.001). There was no significant correlation between sex, age and ER expression in cutaneous and oral PV Conclusion: The results of the present study showed that there were significant differences in the intensity of ER expression between cutaneous and mucosal PV.}, Keywords = {Pemphigus Vulgaris, Estrogen receptor, oral lesions}, volume = {2}, Number = {1}, pages = {6-10}, publisher = {Islamic Azad University Dental Branch }, doi = {10.29252/jrdms.2.1.6}, url = {http://jrdms.dentaliau.ac.ir/article-1-127-en.html}, eprint = {http://jrdms.dentaliau.ac.ir/article-1-127-en.pdf}, journal = {Journal of Research in Dental and Maxillofacial Sciences}, issn = {}, eissn = {2383-2754}, year = {2017} } @article{ author = {hafezi, L and Zareei, A and Bayat, S and Majidi, G and Aliyali, AR}, title = {Efficacy of the Edge Enhancement Filter of Digital Radiography in the Detection of Proximal Enamel Caries in Premolars}, abstract ={Background and Aim: Considering the significance of the detection of proximal caries and the limited information available on the diagnostic value of digital radiography after the use of enhancement filters, this in-vitro study sought to compare the diagnostic value of digital radiography with and without the use of the edge enhancement (EE) filter in the detection of proximal enamel caries in premolars. Materials and Methods: This in-vitro study was conducted on 80 extracted intact human premolars. Every two teeth were mounted in a single block using putty impression material and every two blocks were placed in articulation. Digital bitewing radiographs were taken and saved twice, once in their original form and once after the application of the EE filter. Afterwards, a cavity was prepared on the proximal surface of one of the teeth (chosen randomly) in each block using a bur and then, the tooth was put back in the block. Digital bitewing radiographs were taken again with the same exposure settings. The 80 final images were printed on radiographic films and were evaluated by three oral and maxillofacial radiologists. The results were compared with the gold standard (the cavities formed by a bur). The data were statistically analyzed by Chi-square test. Results: The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were 75%, 87.5%, 85.7%, 77.7% and 81.2%, respectively in the original digital radiographs and 80%, 95%, 94.1%, 82.6% and 87.5%, respectively in the enhanced images. The difference between the two groups was not statistically significant (P=0.7, P=0.3, P=0.3, P=0.7, P=0.3).

This is mostly related to the manner of communication and interaction with the patient and active listening to his/her statements. Registering the information related to the illness and its history has an effective role in patient satisfaction, treatment outcomes, and dental expenses and even in lawsuits against practitioners. Therefore, the present study aimed to compare the average time allocated by general dentists and senior dental students of the dental school of Tehran University of Medical Sciences to obtain the history of the patient's present illness during 2012-2013. Materials and methods: In this cross-sectional study, 60 senior dental students of the dental school of Tehran University of Medical Sciences and 60 general dentists that had been graduated at least five years ago were selected. Each of them randomly selected three patients and recorded the patients' demographics such as age, gender, education level, and the chief complaint or the main reason of the patient's visit. The duration of the patient's statements regarding the present illness and its history was recorded in seconds in the designed questionnaire. Afterwards, the data were analyzed using T-test and Mann-U-Whitney, Kendall-tau and Chi-square tests. Results: The average interview time in the students and dentists groups was 24.41±9.17 seconds and 27.9±7.82 seconds, respectively, which were significantly different according to T-test (p=0.003). Generally, the longest allocated time equaled 49 seconds, while the shortest interview duration was 6 seconds. Conclusion: According to the results of the present study, it seems that dentists do not allocate the necessary and adequate time to gather information about the chief complaint and the history of the patient's reason of referral to guide them towards the correct diagnosis and suitable treatment method, and even the passage of time and the level of experience have no effect on this issue.}, Keywords = {Medical history, listening, illness}, volume = {2}, Number = {1}, pages = {17-24}, publisher = {Islamic Azad University Dental Branch }, doi = {10.29252/jrdms.2.1.17}, url = {http://jrdms.dentaliau.ac.ir/article-1-150-en.html}, eprint = {http://jrdms.dentaliau.ac.ir/article-1-150-en.pdf}, journal = {Journal of Research in Dental and Maxillofacial Sciences}, issn = {}, eissn = {2383-2754}, year = {2017} } @article{ author = {Atai, Z and Navabi, N and khoshroo, SMR and Asadi, L}, title = {Descriptive Analysis of the Medical Consultations Conducted in the Dental School of Kerman University of Medical Sciences}, abstract ={Background and Aim: Medical consultations have an important role in dental diagnosis and treatment planning, and are indicated for patients with uncertain medical histories.

Considering that nowadays, more attention is being paid to dental health and that school health teachers play a key role in the management of dental injuries, this research was designed with the aim of determining the extent of the knowledge of elementary school health teachers of Tehran city on how to control students’ teeth injuries at school. Materials and Methods: This research is a cross-sectional study. The questionnaires were given to 280 elementary school health teachers in Tehran city. Of the 280 questionnaires, 216 were answered (77.14%). Data were collected and statistical analysis was performed using descriptive statistics methods and inferential statistics test in two study populations, chi-square independence and Spearman correlation coefficient with 95% confidence interval (CI). Results: Receiving medical emergency training courses affected the responses to the questions regarding the maximum time to restore the teeth to their location (p = 0.001), and the most appropriate action in case of altered consciousness (p = 0.05). Receiving dental emergency training courses had no impact on the responses to any of the other questions (p = 0.231). According to Spearman correlation test results, there was a weak reverse significant correlation between age and the question regarding the most appropriate way to reposition the teeth in this case (p = 0.031 and correlation coefficient = - 0.157), and between work experience and the question regarding distinguishing the tooth type (p = 0.042 and correlation coefficient = - 0. 153).
