Assessment and evaluation of scientific Output of Iranian Dental researchers during 2010-2017 in ISC

Abstract   Background & aim: The purpose of this study was to evaluate the scientific outputs of Iranian dental researchers in the ISC citation database during the years 2010-2017. Material & Methods: This research is an applied research that has been done by using co-word analysis which is a kind of content analysis and scientometric methods. The statistical population of the study includes 1383 records in dentistry researches that indexed by Iranian researchers in the ISC during 2010-2017. Results: The findings showed that most dental papers were produced by researchers at Tehran University of Medical Sciences. Researchers in our country have also collaborated with US researchers in their papers. The survey of the most commonly used topics showed that the most focus of our researchers is on dental and oral Health. The topic of dental plaque has also been identified as an underdeveloped topic in the fields. Conclusion:  According to the findings, it seems, scientific output of dentistry field in was ISC increased during 2010-2017. and Tehran Medical sciences, Shahid Beheshti medical sciences and Islamic azad university were applied as first to third scores. Background and Aim : One of the concerns of dentists is maxillofacial pain and sinusitis symptoms that be related to presence of Haller's cells. Considering the importance of the issue and the differences in previous studies, the aim of this study was to determine the frequency and apparent characteristics of these cells in Iranian population using digital panoramic radiography. Materials and Methods: In this descriptive study, 650 panoramic radiography, which were in terms of contrast, clarity and darkness were acceptable, were collected from patients with no history of trauma and surgery in the maxillofacial area. Then, the presence of Haller's cell and its apparent features were evaluated and frequency was estimated by statistical analysis with 95% confidence in society and the effect of age, sex and side was judged by Chi-square test. Results: Of the 650 examined samples, 32% had Haller's cell, of which 28.8% were in men and 71.2% in women, and the sex did not play a role in the number of Haller's cell (P <0.4), but Haller's cell in terms of age (Over 39 years old) was found in 81.2% and was not found in 28.7% which was significant (P <0.0001). Most of the Haller's cell were observed to be round (46.2%) and oval (51.4%), frequency of the Haller's cellin left side was 23.5% and in right side was 25.5%. in 50.4% observed in both side. Conclusion:
