- چکیده انگلیسی: Introduction: This study was conducted to determine the pattern of maxillofacial fractures in three age groups of adults, adolescents, and children, using CT scan images. Methods: In this cross-sectional study, CT scan images of 230 patients with maxillofacial trauma during one year were examined in terms of the number and site of fractures. The patients were divided into three age groups, children (0-14 years), adolescents (14-17 years), and adults (>17 years). The data collected from this group were analyzed using, Chi-square, independent t-test and ANOVA statistical tests. Results: The analysis showed that 85% of maxillofacial fractures occur in adults, 7% in adolescents, and 8% in children. The most prevalent causes of fractures in adults were accidents (70%) and fallings (16%). Accidents (73%) and quarrels (13%) were the most prevalent causes of fractures in adolescents. In children, falling (60%) as the most prevalent cause of fracture was significantly higher than that in other groups
(P-value=0.001). The most prevalent sites of maxillofacial fracture in adults were nasal bones and zygomaticomaxillary complex. Nasal and orbital fractures in adolescents comprised the most prevalent sites of fracture. Mandibular bone was the most prevalent site of fracture in children. The variations in prevalent sites of fracture among the three groups were significant (P-value=0.002). Conclusion: Car accidents are the main risk factor for maxillofacial fractures. The prevalent causes and sites of maxillofacial fractures in adults, adolescents, and children are different from one another.- انتشار مقاله: 28-08-1393

- چکیده:
- چکیده انگلیسی: Introduction: Epinephrine-containing lidocaine is the most used anestheic drug in dentistry. The aim of this study was to investigate the hemodynamic changes following local infiltration of 2%lidocaine with 1:80,000 epinephrine in subjects undergoing orthognatic surgery under general anesthesia. Methods: Twenty five patients without any systemic disease participated. After general anesthesia, two cartridges of 2% lidocaine + 1:80,000 epinephrine were infiltrated around the surgery site. Systolic (SBP) and diastolic (DBP) blood pressure, mean arterial blood pressure (MAP), heart rate (HR), and blood sugar (BS) were measured in three stages: before the injection (M1), at the end of injection (M2), and 10 min after injection (M3). Results: No significant difference observed in SBP, DBP, and MAP at the end of injection and 10 min later. HR was increased significantly after injection and remained significantly higher than baseline after 10 min. BS increased slightly at the end of injection and continued to increase after 10 min. However, changes in BS were not significant. Conclusion: Using two cartridges of epinephrine-containing lidocaine have slight systemic changes in healthy subjects; as a result, this dosage could be used in patients with cardiovascular complications undergoing general anesthesia.

- چکیده:
- چکیده انگلیسی: Calcifying odontogenic cyst (COC), Central odontogenic fibroma (COF) and aggressive central giant cell granuloma (CGCG) are rare pathologic diseases affecting the jaws. While the Co-existence of two of them is reported in the literature, existence of all three conditions in one patient is an extremely rare entity. In the present report, initial biopsy revealed fibrosarcoma, therefore mandibular resection was performed for the subject. Sectional Histopathologic evaluation revealed the co-existence of three conditions through histopathologic evaluation. This report emphasizes the importance of precise microscopical evaluation of jaw lesions and thorough sectional examination of the lesions to reach the precise diagnosis. Treatment modalities and follow-up radiographs are also provided to help clinicians manage these entities.
