Tabriz Faculty of Dentistry is located in Tabriz, capital city of East Azarbayjan Province and is the only dental schoolwestern Iran. Tabriz Dental School was founded in 1986. The first students entered in 1987, graduating in 1993. In 1997 the school moved into a new and modern building, covering 22,000 square meters. The school expanded its educational programs in 2001 by offering its postgraduate specialty courses in three fields and at present it offers seven postgraduate specialty courses. Prospects for the Future We are determined, by asking for assistance from the Almighty, to promote the school's academic excellence, raise the standards of oral health in the community and join the circle of highly qualified dental schools in the country through optimizing instruction standards and innovative research programs. Mission Tabriz Faculty of Dentistry as the only dental school in the north-western Iran and as a part of a major university has combined and enjoyed the endeavors of competent and qualified academic staff with appropriate facilities and has committed itself to: Training highly qualified general practitioners and specialists; Updating the knowledge and skill of the graduates working in the north-western Iran;

    Background. Bone deficiency in different areas is problematic in implant placement. Changes in histological, histomorphometric, and radiographic properties of hard tissues in the implant placement area affect many parameters of implant success. Autologous conditioned serum (ACS) is a blood product with high levels of IL-1 receptor antagonists. Augmentation surgeries are required in many cases because implant placement in the edentulous areas requires a sufficient amount of bone. So, this study radiographically evaluated the effect of autologous conditioned serum after horizontal bone augmentation. Methods. In this prospective RCT, 21 patients who were eligible for the study, were evaluated. The patient underwent horizontal ridge augmentation surgery in the area. The ACS-impregnated graft was in direct contact with the bone. The control side underwent the same surgical protocol without using ACS. Four months after surgery, a CBCT radiograph was taken, and radiographic changes in the two areas were calculated using the differences in the amount of bone formed in the horizontal dimension as well as the Hounsfield unit (HU). The data were reported using descriptive statistical methods, including means (standard deviations) and frequencies (percentages) According to the result of the Kolmogorov-Smirnov test, the data had a normal distribution (P>0.05); therefore, paired t-test was used to compare the means of the parameters between the two groups. Results. The results of radiographic examinations showed that the horizontal dimension of bone before surgery was similar between the two groups. However, after surgery in the ACS group (6.1±33.13), it was significantly higher than in the control group (86.4±62.1) (P>0.05). Also, the rate of horizontal dimension increase (the difference before and after surgery) in the ACS group was significantly higher than in the control group. Bone density before surgery was similar between the two groups. However, after surgery, there was a significant increase in the ACS group (330.42±75.56 HUs) compared to the control group (292.38±38.35 HUs) (P>0.05). Also, the rate of density increase (the difference before and after surgery) in the ACS group was significantly higher than in the control group. Conclusion. Radiographic evaluations of hard tissue showed a significant increase in the horizontal dimension of bone and density of newly formed bone using ACS versus control group.

    Comparison of the effect of local and intramuscular injection of dexamethasone on the amount of mouth opening, pain and swelling following surgical removal of impacted mandibular third molars
    (Tabriz University of Medical Sciences, School of dentistry, 2019) Mohammadi, Hamidreza; oral and maxillofacial surgery; nezafati, saeid
    Introduction: The purpose of this clinical trial is to compare the effect of local and intramuscular injection of dexamethasone on the amount of mouth opening, pain and swelling following surgical removal of impacted mandibular third molars. Methods: In this study, 18 patients who referred to dental clinics (facial and maxillofacial surgery department) who have similar bilateral dentures have been selected. After obtaining written consent about their willingness to participate in the study, local and intramuscular injection of dexamethasone was performed and mandibular third molar surgery was performed. During and after surgery, amount of mouth opening, pain and swelling were evaluated after 1, 3 and 7 days period of follow up and the results of the study were analyzed using descriptive statistical methods (mean ± standard deviation and relative frequency) (Percent), and statistical analysis was performed using SPSS17 software and a significant level of P≤0.05 was considered. Results: There was a significant difference between the mean pain severity and the rate of mouth opening in the muscle intramuscular injection group compared to the local injection group, but there was no significant difference between the mean tragus–commisure and lateral cantusn–gonial angle in the two groups under study. Conclusion: Dexamethasone intramuscular injection with more pain intensity and less mouth opening than local inhection was associated with removal of impacted mandibular third molars. Local injection of dexamethasone is recommended to cause fewer complications in surgery of impacted mandibular third molars.
