[Evaluation of patients' satisfaction of departments in Islamic Azad University Dental branch, in 2009]

Patient satisfaction is one of the most important factors to improve the quality of educational centers thus increasing patient referral and promote practical training of the students. To now in this faculty no such study has been done, so this research aimed to evaluate patients' satisfaction from dental care given in different departments of Tehran faculty of dentistry, Islamic Azad University year1387. In this cross sectional study 1500 subjects who referred consequently were selected from clinics with the same proportional ratio of patient referral to every clinic. After explanation of project to every subject through interview, satisfaction was estimated by 13 questions about distant way, waiting time, treatment duration with a range of 3 options of completely satisfied, relatively satisfied, dissatisfied and ranking of 0, 1, 2. Total rank less than 1/3 was known as dissatisfied, between 1/3-2/3 as relatively satisfied, and higher than 2/3 as satisfied. The role of related factors was subjected to chi-square statistics. 71% of all subjects spoke out satisfaction, 27.5% were relatively satisfied, and 1.5% dissatisfied. The prevalence of dissatisfaction in the population was estimated from 26.7% to 31.3%. The most dissatisfaction was related to removable denture patients:64.7% and the least was in oral surgery clinic :13.5% [p<0.05]. The most dissatisfaction factor was long distance and waiting room ambiance but the least dissatisfaction was about student behavior, hygiene and professors behavior. The satisfaction level of patients in Tehran dental faculty of Islamic Azad University was acceptable but according to presence of dissatisfaction in patients and its consequences, appropriate improvements are recommended

[Plates and screws removal after sagital split osteotomy]

In contemporary orthognatic surgery, osteotomy and rigid internal fixation procedures are commonly used to restore stability and function of the jaws, and to obtain comfort for patients. Although there are many good reasons for utilization of this type of fixation, in some patients the need to remove plates and screws after surgery may arise due to related complications. The present study investigated plate removal after sagital split osteotomy and its reasons. In this prospective study, 67 patients in need of sagital spilt osteotomy or bimaxillary osteotomy were selected from two university departments during the period of 2005 to 2007. All patients were followed up for 14 month after surgery and number of plates removed was recorded. In addition, information regarding age, sex, duration of operation, medical condition, splitting during surgery, smoking habits, and need to extract wisdom teeth at the time of surgery were gathered. The data were analyzed using a linear logistic regression model with the SPSS software version 12. Infection was the sole reason for plate removal in this study. From 134 plates used in 67 patients 14 plates [10.5%] were removed in 10 patients. Age was the only statistically significant factor to affect plate removal and the effect of other factors were not statistically significant. According to the findings of this study only a few patients needed plate removal. Routine removal of plate does not appear to be clinically indicated

[Evaluation of 79 patients with oroantral and oronasal fistula]

Various methods for closure of oroantral communication [OAC] and oronasal communication [ONC] have been reported. These are different based on the skill of surgeon, type of communication, size and location of defect and other factors. The purpose of this study was to evaluate the etiologic factors, location, type of treatment and surgical results in patients with oronasal and oroantral communications. In this descriptive study, between 2005-2007. 79 patients with OAC or ONC were evaluated for aforementioned factors. The data were statistically analyzed by Chisquare and Odd's ratio tests. Seventy nine patients including 9 patients with ONC and 70 patients with OAC were studied. The main etiologic factor for both OAC and ONC was tooth extraction. The surgical technique most frequently used for treatment of both OAC and ONC was suturing. Surgical failure occurred in 4 cases with OAC and 3 cases with ONC after first surgery. According to the results of this study, tooth extraction was the most etiologic factor for OAC and ONC. Suturing for small communications and use of a buccal fat pad flap for larger defects, seem to be the best choices for treatment

[Evaluation of histopathologic changes in impacted third molar follicles in Mashhad dental school in 2005]

Since remaining impacted teeth may result in pathologic lesions, prophylactic extraction of third molar-which is the most frequent impaction-is among the most common surgical procedures. Our study was performed to evaluate the histopathoiogical changes of impacted molar teeth follicles. In this descriptive study, 54 impacted molar teeth follicles of 50 patients with age range of 15-38, and examined in the surgery ward of Mashhad dental school from June to November 2005, were extracted by a surgeon and pathologic evaluation were performed. In this study, the most commonly extracted teeth were mandibular molars [79%] and 74% of patients were under 25. The most frequent location of the extracted teeth was mesioangular [46%]. In microscopic evaluation of specimens, 61% were unchanged dental follicles, 12.9% were odontogenic cysts and 24% had inflammation. Considering the low incidence of pathologic changes in impacted third molar follicles, it is better not to extract them except in a clear indication. These teeth are better to be monitored by imaging with the 6-12 month intervals

[Evaluation the bleeding in patients maintained on oral anticoagulant therapy without interruption of their treatment after use of tranexamic acid mouthwash]

Today many patients with some reasons need the use of anticoagulant drugs ,that interruption of this drugs may be dangerous. The purpose of this study was to evaluate the use of tranexamic acid 5% mouthwash to control hemostasis in patients therapeutically anticoagulant medication undergo dental extraction without interruption of medication. This study was a descriptive study and the data collection method was direct observation. A total of 55 patients undergone 167 dental extraction without interruption of oral anticoagulant medication, were required to rinse with 10 ml of a tranexamic acid 5% mouthwash 4 times a day for 7 days postoperatively. Dental extraction was carried out by two surgeon. Data were analyzed using SPSS statistical software and descriptive analyzed done. Of 55 patients treated, 1 presented with postoperative bleeding on the third day after operation [1/8%]. In this patient international normalized ratios was grossly elevated on the day of the bleeding [6.1]. This study supports the consensus that simple dental extraction in patients maintained on oral anticoagulant therapy with use tranexamic acid 5% mouthwash, can be performed without reduction or intruption dose of anticoagulant medication, and hemostas occurred well

[Evaluation of the effect of sagital split osteotomy on mandibular range of motion due to mandibular setback]

In the orthognatic surgery of the mandible and specially bilateral sagital spilt osteotomy [B.S.S.O], the most complication is some change in mandibular border movement, and as a result limitation of mandibular movement. The aim of this study was to evaluate the changes in maximum interincisal opening, left and right lateral excursion, and protrusive movements in all patients before and after operation in the period of three to six months and the effects of modern physiotherapical plans [CPM] on increasing these movements after surgery. This is a prospective clinical trial study. In this study 30 patients [18 females and 12 males] who were 13-30 years old [average age 20.5], BSSO surgery was performed according to Epker procedure with surgical handpice and bur, rigid fixation were performed with 3 postional screw of 2mm diameter for all patients. MIO, LLE, RLE, PM were measured before and after operation in the period of three to six months. At the end the patients who still had mandibular movement limitations were divided into two groups of experiment and sample, then the effects of 20 physiotherapical sessions were studied after the 9th month. After 3 months post-op, considerable reduction in all mandibular movements has occured, but after 6 months post-op, 12 patients [40%] had significant limitation of mandibular movements, specially in MIO and PM. At the end of nine months post-op all patients in sample group, had limitation in mandibular mobility but in the experiment group all patients had normal mandibular border movement. There are different reports about the effect of orthognatic surgery on mandibular border movements. In this study BSSO for mandibular setback has led to considerable reduction in mandibular movement sepecially maximum interincisal opening and protrusive movements and the physiotherapical treatment have been considered as the solution of the mentioned problems but the major difference between our study and others are, using of Rigid fixation, not using MMF and two week usage of elastic Traning

Dental extractions in patients maintained on oral anticoagulant therapy: comparison of International Normalized Ratio [INR] value with occurrence of postoperative bleeding

The purpose of this study was to evaluate the incidence of postoperative bleeding in patients treated with oral anticoagulant medication undergone dental extraction without interruption of medication and to compare the incidence of postoperative bleeding with International Normalized Ratio [INR] value. This study was a cross sectional study and the data collecting method was direct observation. A total of 362 patients undergone 703 dental extractions without interruption of oral anticoagulant medication were studied. For all patients INR value was measured on the day of surgery and based on INR value, the patients were divided into three groups: Group I with INR of 1.5-2.49, Group2 with INR of 2.5-3.49, and Group 3 with INR of> 3.5. Dental extraction was carried out by two surgeon and if necessary, local hemostatic agents were applied [gelfoam and multiple silk sutures]. The data were analyzed using SPSS 11.5 statistical software [Willcoxan and Mann-Whitney tests]. Of the 360 patients undergone oral anticoagulant medication, in 30 patients postoperative bleeding occurred. 11 patients [7.43%] in group one, 10 patients [8.62%] in group two and 9 patients [9.18%] in group three, developed postoperative bleeding. The incidence of postoperative bleeding was not significantly different in three groups. Thus simple dental extractions can be performed without modification of oral anticoagulant therapy. Local hemostasis using gelfoam and sutures would be sufficient to control postoperative bleeding

Evaluation of the rate of knowledge of health care workers toward hepatitis B at Mashhad Dental School in Autumn 2003

Hepatitis B is a primary viral infection of liver which is of high importance, clinically as well as socioeconomically, due to its capacity in producing chronic state. One of its significant routes of transmission is blood and contaminated fluids, items and surfaces with blood. Since health care workers are always in touch with patient's blood and their blood contaminated secretions, they are considered as high risk groups. Thus, their knowledgibility toward hepatitis B and its routes of transmission is important. The purpose of this study was to determine the knowledge rate of health care workers [apart from dentists] toward hepatitis B at Mashhad Dental School. In this descriptive study, all of the health care workers apart from dentists at Mashhad dental school were given a questionnaire concerning hepatitis B complications, its routes of transmission and methods of prevention. Totally, 170 questionnaires were analysed using SPSS statistical software. The nurses had the highest rate of knowledge. 16.6% had an agreeable knowledge about routes of transmission, 33/3% about complications and 50% about the methods of prevention. The servants had the lowest rate of knowledge, more than 90% of whom had little or very little knowledge about routes of transmission, complications and prevention methods [94%, 93% and 95/5% respectively]. None of them had an agreeable knowledge state about any of the studied variables of hepatitis B. This study revealed that the rate of knowledge increased with level of education. The nurses had the highest education and rate of knowledge and the servants had the lowest education and rate of knowledge. Although health care workers were more knowledgable about preventive methods than complications and transmission routes, a number of them had not been vaccinated against hepatitis B. This implies that the health care workers commitment toward hepatitis B is not at an agreeable state and necessitates continuous educational strategies as well as supervision over their practice

[Unilateral coronoid process hyperplasia causing restricted opening of the mandible and facial asymmetry-Report of a case]

Introduction: hyperplasia of the coronoid process of the mandible is a rare developmental anomaly and may be unilateral or bilateral. Unilateral enlargement of the coronoid process can result from a true tumor, such as an osteochondroma or osteoma. The purpose of this case report is its abnormal sits as well as rarity

Results and discussion: an enlarged coronoid process impinging on the posterior surface of the zygoma restricting mandibular opening and facial asymmetry and fracture of zygomatic arch was detected. Coronoidectomy was done for the patient under general anesthesia via an intraoral approach

Conclusion: one of the differential diagnosis of restricted mandibular opening is coronoid process hyperplasia. Treatment of coronoid hyperplasia consists of surgical removal of the enlarged coronoid process or processes to allow freedom of mandibular motion. Coronoidectomy is usually accomplished via an intraoral approach. Conventional radiographic techniques do not fully reveal the size and mushroom-shaped coronoid process, so CT Scanning and tomography is suggested
