Introduction: Saliva as a simple non-invasive method of gaining body fluids has been used to detect the thyroid hormones. A single method for determining these hormones has not been clearly stated in the literature. Furthermore, thyroid diseases would affect the salivary glands and may compromise salivary flow.Materials and Methods: A comprehensive search was conducted using PubMed and Medline.Conclusion: Saliva can successfully be used as a non-invasive method for determining thyroid hormones and for detecting and monitoring thyroid dysfunctions. Thyroid dysfunctions also have a great impact on salivary gland functions and saliva.

Introduction: This study was conducted to investigate the side effects of closed reduction method as a treatment modality of unilateral condylar fractures of the mandible in patients referred to Shahid Beheshti University Hospital (Babol, Iran) over than one decade (2002 to 2012).Materials and Methods: To accomplish this study, patient’s data were collected referring to their files in Shahid Beheshti University Hospital. Cases with unilateral condylar fractures of the mandible aged older than 12 who treated by closed reduction technique; were selected. Finally, 24 out of 78 selected patients entered to this study. Considering the variants such as age, gender, maximum mouth opening (MMO), mandibular deviation from midline on MMO and patient’s satisfaction of mastication were captured.Result: About 24 patients, 18 males (75%) and 6 females (25%) aged from 13 to 52 and the mean age of 24.7, were included in this study. The MMO of 23 cases (95.83%) were in normal range (7 35 mm); 23 patients (95.83%) were satisfied with their quality of mastication. 17 cases (70.83%) out of all patients had no deviation during mouth opening.Conclusion: According to low complication rate of closed reduction of mandibular condylar fractures deduced in this study, it may be acceptable as a conservative treatment modality.

Introduction: Fractures of the orbital floor, which are caused by various mechanisms, result in the herniation of periorbital tissue into the paranasal sinuses and its subsequent complications. Early diagnosis using various techniques and reduction of fractures are necessary to preserve ocular function and esthetic. Use of an endoscope has been associated with some advantages, including a decrease in the number of external incisions and soft tissue manipulations. The aim of the present study was to evaluate complications of reducing fractures of the orbital floor and the infra-orbital rim with the use of an endoscope and conventional techniques.Materials and Methods: A total of 40 patients with fractures of the orbital floor were included in this clinical trial. The subjects were equally divided into two groups (n = 20). In Group 1, the complications of treatment with an endoscopic view were evaluated in addition to comparison of the sensitivity of endoscope and 3-mm computed tomography (CT) slices with the gold standard. In Group 2, complications of treatment with the conventional technique were compared with those in Group 1. T-test, chi-squared and Fisher’s exact tests, ANOVA and Tukey test for multiple comparisons were used for statistical analyses with SPSS statistical software.Result: There were no statistically significant differences between the two groups regarding age and gender. The sensitivity of the endoscope-assisted surgery in comparison to the gold standard was estimated to be 70% with a sensitivity of 85% in comparison to 3-mm CT scan slices. There was a significant difference between the two groups regarding complications, including edema, lower eyelid scars (P = 0.024), indicating superiority of the endoscope-assisted technique.Conclusion: The present study showed the importance of the CT scan as a diagnostic technique. In addition, the efficacy of the endoscopic technique in decreasing complications and improving the quality of orbital floor fracture treatment outcomes was confirmed.

Introduction: The main purpose of this study was to evaluate the prevalence of ophthalmic injuries associated with mid-facial fractures in patients admitted to Shahid Beheshti University Hospital in Babol, Iran, from 2002 to 2012.Materials and Methods: A cross-sectional, retrospective study was undertaken to determine the prevalence of ophthalmic injuries associated with mid-facial fractures in patients admitted to a university hospital over a decade (2002-2012). Relevant data, including history, operation notes, and consultation sheets, were collected using patients’ medical records. The types and frequencies of maxillofacial and concurrent ophthalmic injuries were derived and represented by figures and percentages.Result: A total of 196 medical charts of patients with mid-facial trauma were reviewed. Coexistent ophthalmic injuries were seen in 106 cases (93 males and 13 females). The mean age at the time of trauma was 31.01 ± 12.40. The most common cause of mid-facial trauma was motor-vehicle accidents (85.5%). Patients as a whole had 169 fractures. A bilateral orbital fracture was the most common fracture detected in this study (37.4% of the patients). Overall, 197 ophthalmic injuries were observed. Peri-orbital ecchymosis (68.3%) and blurred vision (12%) were the most common types of minor and major injuries, respectively.Conclusion: Serious ophthalmic injuries, such as permanent visual loss, retinal hemorrhage, laceration of cornea, and globe rupture, were at the low ebb in this survey; however, they must be ruled out in all mid-facial fractures by meticulous ophthalmologic examination. Because mid-facial fractures are potentially detrimental to orbital contents, an ophthalmologic consultation is mandatory and must be prioritized before embarking on performing maxillofacial surgical interventions.

Introduction: Periodontitis is a multi-factorial inflammatory disease of periodontium. A precise mechanism in which smoking affects periodontium is not accurately understood. This study was planned to survey salivary osteocalcin (OC) level among smokers with chronic periodontitis and its comparison to non-smoker patients which may help achieve a better understanding of mechanisms being involved in beginning and developing of periodontal disease.Materials and Methods: This case-control study was done among patients referred to Babol Dental School. The patients who had systemic disease or who had been taking intervening drugs, and alsothe patients who were under periodontal treatment at least 6 months before the start of the study, were excluded. Thirty-five patients with history of smoking 10 cigarettes/day during at least 5 years entered into case group and 35 patients who had not smoked, and did not have a smoking history in the past, entered the control group (both groups had periodontitis). Clinical parameters according to Ramfjord system, including clinical attachment loss (CAL) and probing pocket depth (PPD) were recorded. One milliliter of unstimulated saliva of patients was collected in tubes and stored at −80° C. Enzyme-linked immunosorbent assay test was done to evaluate the salivary OC levels. The data were analyzed with Mann–Whitney test.Result: The mean age in case group was 43.03 (± 7.71) and 40.37 (± 5.73) years in the control group. There was no statistically significant difference in salivary OC levels between two groups (P > 0.050), but the average of PPD and CAL were significantly higher in case group and the difference was statistically significant (P < 0.050).Conclusion: Our study showed that smoking and periodontal diseases are associated, but the present study did not prove the destructive effects of smoking on periodontal tissues by changing the salivary levels of OC.

Introduction: The aim of this study was to evaluate mental health in temporomandibular disorders (TMD) patients considering: Gender, age, and grade of chronic pain scales (GCPS).Materials and Methods: The data were collected using general health questionnaire (GHQ-28) for evaluating mental health and research diagnostic criteria for TMD for evaluating GCPS, age, and gender from 75 TMD patient seeking treatment at Dental School of Tehran University of Medical Science and Shariati Hospital during 13 months and 75 also non-patient group without TMD diagnosis.Result: According to the results from GHQ questionnaire, total scores of the questionnaire which shows mental impairment and all subscales except for social dysfunction were significantly higher in patients in comparison with non-patients (P < 0.0500). Patients with higher GCPS had higher scores in subscales of GHQ-28 and its total score (P < 0.0500) except for ‘‘social dysfunction.’’ Considering gender in the patient group except for social dysfunction TMD had greater impacts on women’s mental health rather than men. Older individuals revealed the lower likelihood of being depressed.Conclusion: TMD and chronic pain affect mental health negatively so that patients have the poorer mental health in comparison with non-patients.

Introduction: Mandibular resection usually results in altered mandibular movements, disfigurement,and difficulty in swallowing, impaired speech/articulation and deviation of the mandible toward theresected site. To overcome this impairment, numerous prosthetic methods, such asmaxillomandibular fixation, implant supported prosthesis, removable mandibular guide flangeprosthesis, and palatal based guidance restoration have been employed to reduce or minimizedeviation and to improve function. However, the management of these mandibular resected patientsis difficult.Case Report: This article tries to describe step by step prosthetic management of a patient, who hassuffered from mandibular resection.Conclusion: This treatment modality seems to be the treatment of choice. In our patient, theadequate intercuspal position was obtained but due to compromised tongue mobility, the guideflange prosthesis, like other treatment options could not improve patient’s mastication ideally.
