Introduction: Sealing ability of a retrograde filling material is an important factor for a successful endodontic apicoectomy. The purpose of this in-vitro study was to compare the sealing ability of calcium enriched mixture (CEM) cement versus amalgam as root-end filling materials. Methods: A total of 36 canals of extracted maxillary central incisors were instrumented and obturated using lateral compaction technique. The apical 3 mm of each root was resected and root-end prepared to a depth of 3mm.The teeth were randomly divided into two experimental groups of 15 teeth according to tested materials (Amalgam, CEM cement) and two negative and positive control groups of 3 teeth. Root- end cavities were restored with amalgam (group 1) or CEM (group 2). Sealing ability was evaluated by dye penetration method using Pelikan ink, and a stereomicroscope at x10 magnifications and 0.01 mm accuracy. Data were analyzed by T-test and PResults: The mean linear dye microleakage for CEM cement and amalgam retrofilled groups were 2.08 and 3.77 mm, respectively. There was a statistically significant difference between the two groups (p<0.0001). Conclusion: under the condition of this in vitro study, CEM cement provides a better seal than amalgam when used as a retrograde filling material.

Statement of the problem: Nowadays leishmaniasis is a common infectious disease around the world which is caused by a protozoan parasite named Leishmania. This parasite is transmitted to human by an infected female sand fly. This disease has three clinical forms; mucosal forms are rare in Iran. Purpose: The purpose of this study was to report a case of leishmaniasis with lip and oral mucosal involvement that healed successfully. Results: This article is about patients with lip leishmaniasis with oral-mucosal involvement, clinical features were diffuse lip swelling and ulcer in right lower lip vermilion and buccal mucosa. A smear was caught which proved the diagnosis of leishmaniasis. Thereafter, the patients were referred to a dermatologist for treatment and follow up showed complete healing of the lesions. Conclusion: Oral mucosal leishmaniasis is rare. However, the swelling may cause different complications like loss of teeth or respiratory obstruction. It should be noted that time is a key point in treatment. So, it is necessary for us to train the differential diagnosis of chronic ulcerated oral lesions to our dentists.

Introduction: In patients susceptible to infection, after dental procedures which lead to soft tissue manipulation or bleeding, the occurrence of bacteremia is probable. Hence, antibiotic prophylaxis is very important in this group of patients. The purpose of this study was to assess the level of awareness of senior dental students and general dental practitioners in the city of Yazd about the indications of antibiotics prophylaxis and the proper way of prescribing the prophylactic regimens. Materials and methods: This study is a cross-sectional descriptive-analytical study. To collecting data, prepared questionnaires distributed among 60 general dentists and 60 senior students. Results: The mean of knowledge scores of senior dental students and general dentists were 55.43 and 55.06 respectively. Both groups showed acceptable levels of knowledge. Conclusion: The levels of knowledge of senior dental students and general dental practitioners were desirable and this may be due to the participation of practitioners in relevant re-training programs or allocation of related academic resources in this area during their education.

Osteosarcoma (OS) is a malignant tumor that induces formation of osteoid or immature bone and rarely occurs in maxilla. Maxillofacial OSs are reported to occur in the third to fifth decades that is 1-2 decades later than the mean age for OS of long bones. The present case is a 62-year-old man with facial asymmetry and pain in his left upper jaw. Intraoral examination showed a bony hard, tender swelling about 50 x 60 mm in diameter in the maxillary alveolar ridge extending unilaterally from the maxillary incisor to the molar region which had expanded the buccal and palatal aspects of alveolar ridge. Computed tomography showed a hyper dense mass in the left maxilla extending to maxillary sinus. The diagnosis of OS was confirmed by histopathologic evaluation. Following the initial surgery, a local recurrence developed in the facial region of the patient within 18 months. Radiographic evaluation of OS of maxilla is important for diagnosis. Early diagnosis and radical surgery are the keys to increasing survival rate.
骨肉瘤(Osteosarcoma, OS)是一种诱发类骨或未成熟骨形成的恶性肿瘤，很少发生在上颌骨。据报道，颌面部骨缺损发生在第三至第五十年，比长骨骨缺损的平均年龄晚1-2年。本病例为62岁男性，面部不对称，左上颚疼痛。口腔内检查显示，上颌牙槽嵴有一硬而柔软的骨性肿胀，直径约50 x 60 mm，单侧从上颌切牙延伸至磨牙区，扩大了牙槽嵴的颊部和腭部。计算机断层扫描显示左上颌有一高密度肿块，并延伸至上颌窦。经组织病理学检查证实为OS。初次手术后，18个月内患者面部局部复发。上颌骨骨缺损的影像学评价对诊断具有重要意义。早期诊断和根治性手术是提高生存率的关键。

The simplest and fastest way of producing an acceptable and accurate cast is by adopting the two-pour or inversion method. This process is slightly cumbersome and messy due to difficulty of access. A much more efficient, easy and artistic way of accomplishing it is described by adopting a Rotating Cake Icing Table with a Silicone Baking Mat on top as an autoclavable non-stick barrier.

Background: Different soldering techniques have a variety of applications in dentistry. One of the most important uses of soldering is to join multiple-unit fixed partial dentures together. In this Study, two base metal alloys (Supercast and Minalux) were soldered and their tensile, compressive and flexural strengths were measured and compared to each other. Materials and methods: In this in-vitro study, an aluminum pattern was made by a milling machine according to ASTM (American Society for Testing Material). Eighteen acrylic resin Patterns were duplicated by flasking using putty indices according to the original aluminum pattern. Acrylic resin patterns were divided into two groups of nine and each group was cast with two different alloys named Supercast and Minalux. All eighteen metal rods were separated by 0.008-inch disc and soldered with Vera-solder by means of gas-oxygen torch. Three patterns of each alloy were selected for each of the compression, tensile and flexural tests. Tensile strength was measured by Instron a universal machine and flexural and compression strengths were measured by Dartec machine. Statistical analysis was done by Mann - Whitney test. Results: The mean tensile, flexural and compressive strengths for supercast alloy was 347.6, 44.01 and 1014.8MPa respectively and the mean for tensile, flexural and compressive strengths for Minalux alloy was 350.03, 51.70 and 938.17 MPa respectively. Statistical analysis showed no significant differences between the two alloys in all the three mentioned tests. (p>0.05) Conclusion: Tensile, flexural and compressive strengths of the two soldered alloys, Minalux and supercast, showed no significant differences. Minalux is an alloy manufactured in Iran with the advantage of not including Beryllium, a cariogenic element, as one of the ingredients of the alloy; therefore, it is suggested that Minalux be used instead of supercast in soldering procedures in fixed prosthodontics.

Statement of the Problem: Anxiety is one of the most common factors hindering people from visiting dentists. Therefore, finding a solution for stress control has been a significant issue in recent studies. It seems that music positively affects inhibition of psychological stress. Other studies have shown that aroma may adjust perception, patience and moods. Purpose: This study investigated the effect of music and lavenderâ��s aroma on blood pressure, heart rate and anxiety. Materials and Method: Ninety patients were divided into three groups. At the beginning, patients were asked to complete Spielbergerâ��s questionnaire to assess the level of anxiety. Blood pressure and heart rate were also measured. In the first group, surgery was performed, while the patient smelled the fragrance of lavender; in the second group, surgery was accompanied by playing a relaxing music and in the third group, no intervention was done. Then, patients were again requested to complete the questionnaire and their blood pressure and heart rate were again measured. Results: In the control group, no statistically or clinically significant difference was observed in systolic and diastolic blood pressure or heart rate. In the aroma therapy and music groups, systolic and diastolic blood pressure values didnâ��t change clinically but heart rates were decreased. In the control and music groups, anxiety levels didnâ��t change significantly but in the aroma therapy group, anxiety had a significant decrease. Conclusion: Using aroma and relaxing music, regardless of whether it affects or not on anxiety, aroused pleasant feelings in patients.  Â

Introduction:Many different kinds of chewing gum can increase the flow of saliva, and they have been proven to have anti-bacterial effects as well. The aim of this study was to compare the effect of natural turpentine and synthetic sugar-free gums on dental plaque pH after a sucrose challenge. Methods: This randomized clinical trial was conducted on 15 subjects, who refrained from oral hygiene for two days and rinsed with 10% sucrose solution. Then for 30 minutes, they chewed one of three sugar-free gums: Van (natural), Orbit Complete, Orbit (synthetic), or one sugar-containing chewing gum (Banana). One group did not receive any gum (control group). Plaque pH was measured by the plaque sampling method before rinsing with sucrose, and 5, 10, 15, 20, and 30 minutes after chewing. Results: The lowest plaque pH drop was seen in the Orbit Complete group, and the highest was in the Banana group. The pH increased faster with Van and Orbit Complete gums. The plaque pH was more than baseline pH after 20 minutes in the Van and Orbit Complete groups (P<0.001). Conclusion: All the three sugar-free gums were effective, although the pH recovery was higher and faster in the Van and Orbit complete groups.

The aim of this study was to compare the effect of natural turpentine and synthetic sugar-free gums on dental plaque pH after a sucrose challenge. Methods: This randomized clinical trial was conducted on 15 subjects, who refrained from oral hygiene for two days and rinsed with 10% sucrose solution. Then for 30 minutes, they chewed one of three sugar-free gums: Van (natural), Orbit Complete, Orbit (synthetic), or one sugar-containing chewing gum (Banana). One group did not receive any gum (control group). Plaque pH was measured by the plaque sampling method before rinsing with sucrose, and 5, 10, 15, 20, and 30 minutes after chewing.
