Abstract
Guided Tissue Regeneration (GTR) is the most recent and common method for regeneration of class II forcation molars. However, it requires membrane, which seems expensive for most of the patients. In order to overcome this problem, Coronally Position Flap (CPF) procedure may be applied which arresting the epithelial cell down growth, follow the same aim. This study is aimed to compare GTR technique utilizing bioresorable collagen membrane and CPF utilizing citric acid. Nine patients with grade II forcation defects were selected. Defects were bilateral that randomly assigned into two groups: GTR and CPF groups. Measurements recorded at baseline and after surgery (6 months). Paired-T test was performed on these data. The following results were obtained after 6 months: In both groups significant reduction in probing pocket depth were measured in GTR and CPF groups, 1.55 Ind 1.88 mm, respectively. Also, open vertical probing depth: 0.33, 1.11 mm. Reduction in forcation weight in both groups was 0.22 mm. Bone fill was observed in 0.33% and 51% of defects. No recession was observed in GTR group, in CPF was 0.11 mm. Loss of attached gingiva was 0.34 and 0.78 mm, respectively. No significant difference was found between clinical parameters except OHPD. Comparison of means at the day (0 and 180) in each group showed the success for regeneration of forca. Considering the results, it can be concluded that CPF may substitute for GTR technique.

Abstract
During pregnancy, different froms of periodontal disease such as pregnancy gingivitis, pregnancy tumors, pregnancy stomatitis, may be encountered. But the most considerable point is the pregnant women's infection with periodontal disease and its effect on delivery and weight of newborn infants. Based on the latest researches and statistics, it is concluded that periodontal disease is an important risk factor, leading to preterm or premature delivery. On the other hand, poor hygiene, should be considered as another danger, resulting in premature delivery. Besides, the presence of a collection of oral fosobacteria in ammoniutic fluid in mothers with premature delivery, increases the probability of an oral- haematogenous connection. Moreover, prostaglandin E2, in cervicular fluid, has been considered as an index for periodontal disease activity and loss of weight at the time of birth. These findings suggest that effective steps, to prevent preterm delivery, can be taken, if women, genycologists and dentists have enough knowledge. This article focuses on the special supervision that is required to prevent the effects of hormonal changes on periodontal tissues and conversely to reduce systemic disorders resulting from periodontal disease, in pregnant woman.

Abstract
Statement of Problem: One of the problems associated with the treatment of periodontal diseases is caused through the extension of disease toward furcation area. Several techniques in Conservative, Resective and Regenerative categories have been suggested for the treatment of furcation involvement.
Purpose: The aim of this study was to compare the results of the treatment of grade II furcation involvement in mandibular molars using an allograft material named 'Dynagraft' (a type of demineralized bone matrix) and the coronally positioned flap.
Materials and Methods: In this randomized controlled clinical trial study, twelve patients (9 females and 3 males), aged 25 to 40, suffering from bilaterally grade II furcation involvement of mandibular molars who referred to dental faculty Tehran University of medical Sciences, were investigated. The molars of one side were treated by Dynagraft whereas those of the opposite side underwent the CPF method. Measurements of the probing pocket depth (PPD), clinical attachment level (CAL), keratinized gingiva (KG) and horizontal probing depth (HPD) were recorded at baseline, 3 and 6 months after surgery. In order to investigate the bone radiographic changes, radiovisiography at the mentioned periods in addition to clinical investigation, were performed. For statistical analysis, Paired West was used.
Results: The mean PPD reduction three months and six months after the operation were 1.75 mm and 2.25mm, respectively in the Dynagraft (test) group whereas 1.26mm and 1.27mm in the CPF (control) group (P<0.005). The mean attachment gain three months and six months after the operation were 1.1 mm and 1.5mm respectively in the test group, and 0.2mm and 0.3mm in the control group (P<0.005). The mean KG reduction three months and six months after the operation were 0.5mm and 0.6mm respectively in the test group and those of the control group were 1.1mm and 1.1mm. The mean HPD reduction three months and six months after the operation were 1.55mm and 2mm respectively in the test group (P<0.005) and 0.55mm and 0.55mm in the control group (PO.01). Radiovisiography of the mentioned areas three months and six months after the operation confirmed the changes obtained from clinical measurements, showing appreciable reconstructive results (Bone filling) in the test group as compared with the control group. Moreover, root resorption was not observed.
Conclusion: Based on the results of this study, Dynagraft can be used as an appropriate material in the treatment of grade II furcation involvement in mandibular molars. However, for a through evaluation of such regenerative techniques in furcation involvement, further studies with larger population and long term follow up in addition to histologic studies are suggested.

Abstract
Background and Aim: Intrabony periodontal defects are important problems in periodontology and up to now several ways have been suggested for their treatment .Treatment with enamel matrix derivatives (EMD) has been shown to enhance periodontal regeneration. There is limited information available from clinical trials regarding the performance of EMD in the treatment of periodontal intrabony defects. This study was designed to compare the clinical and radiographic effects of EMD treatment to that of open flap debridment (OFD) for two and three walled intrabony defects.
Materials and Methods: 18 patients were included in this clinical trial which have 24 two and/ or three intrabony defects. Defects were randomly divided into two groups (test and control). Defects in test group were treated with flap surgery plus EMD and in control group with open flap debridment. At baseline and at 3 and 6 months follow up, clinical and radiographic measurements were performed. Data were analyzed using Greenhouse-Geisser test with p<0.05 as the limit of significance.
Results: At 3 and 6 months, mean probing pocket depth reduction was greater in the test group (EMD) (4.33 mm and 4.70 mm) compared to the OFD group (2.54 mm and 3.09 mm). Mean values for clinical attachment gain in the EMD group after 3 and 6 months were 4.29 mm and 4.98 mm, and in OFD group were 2.83 and 2.82 mm respectively. Radiographic bone gain measured by radiovisiography technique was greater in the EMD group compared to the OFD group (4.66 mm in EMD and 1.11 mm in OFD group after 3 months and 5.78 mm in EMD and 1.39 mm in OFD group after 6 months).
Conclusion: Based on the results of this study, treatment with flap surgery and EMD compared to open flap debridment, produced more favorable clinical improvements in two and three walled intrabony defects.

Abstract
Background and Aim: Qigong is a type of Chinese psychosomatic exercise that integrates meditation, slow physical movements, and breathing. Numerous physical and mental benefits have been classically ascribed to qigong. On the other hand, unstimulated saliva is thought to play an important role in oral immunity, enamel stability and moisturizing the oral mucous membrane. Impaired salivary secretion leads to dental caries, mucosal deterioration and mouth dryness. The aim of the present study was to analyze the effect of a qigong program on various parameters of saliva such as quantity of unstimulated saliva, pH and SIgA.
Materials and Methods: Twenty three subjects participated in this clinical trial study. The experimental subjects underwent a qigong training program, conducted by a qualified instructor. The program consisted of half an hour daily practice for 6 months (spring and winter). Saliva was collected in two periods: once during the spring before the experiment commencement and the second, in the following spring. During each period saliva collection was done on tuesday of each week. pH and quantity of salvia measurements were taken simultaneously. SIgA measurements were also taken based on the values obtained in the last phase of the experiment at the end of each spring. The results were analyzed using paired sample T test, one way repeated measure and Bon Ferroni multiple comparison. P<0.05 was the level of significance. Results: Based on our findings, the change in the amount of unstimulated salvia as well as SIgA was statistically significant (P<0.001) however, there was no significant difference in pH values before and after experiment.
Conclusion: These findings demonstrate that after 6 months of practicing qigong, significant changes in amount of unstimulated saliva and SIgA occurred in participants. The authors suggest that qigong may be a beneficial adjunctive treatment that enhances amount of unstimulated saliva and SIgA.

Abstract
Background and Aim: Improving esthetics is a major goal in periodontal treatments and specially reconstruction of dental papilla is of great importance. Different techniques have been developed, however the results are not completely predictable. The aim of the present study was to compare the possibility of papilla reconstruction using connective tissue graft with and without Emdogain.
Materials and Methods: In this clinical trial, 40 class II lost interdental papilla (Nordland- Tarnow classification) in 18 patients (4 male and 14 female) were studied. Samples were randomly devided into two groups. Case group was treated by connective tissue graft and emdogain (Straumann-USA) and controls were treated using connective tissue graft only. Periodontal parameters including papilla height (PH), periodontal pocket depth (PPD) and clinical attachment level (CAL) were measured before surgery, and 3 and 6 months after treatment. At the tenth days and 1 month after treatment only the papilla height was measured. Repeated measures analysis was used for data analysis with p<0.05 as the level of significance.
Results: In the control group the mean papilla height changed from 3.38 0.89 to 2.85 0.93 on the 3rd month and 2.90 0.95 on the 6th month. The mean PPD changed from 2.8 0.68 to 2.55 0.70 on the 3rd month and 3.06 1.25 on the 6th month. The mean CAL changed from 3.88 1.29 to 3.79 1.25 on the 3rd month and 4.11 1.44 on the 6th month. In test group the mean papilla height changed from 2.98 0.91 to 2.45 1.55 on the 3rd month and 2.55 1.48 on the 6th month. The mean PPD changed from 2.75 1.49 to 2.63 1.38 on the 3rd month and 2.88 1.39 on the 6th month. The mean CAL changed from 3.75 1.24 to 4.01 1.45 on the 3rd month and 4.28 1.63 on the 6th month. These differences were not significant between the studied groups (P>0.05).
Conclusion: Based on the results of this study, use of connective tissue with or without emdogain is not effective in interdental papilla reconstruction.

Abstract
Background and Aims: Evaluation is a continuous process which is necessary for improvement of students learning and planning for required changes to obtain the educational objectives. The aim of the present study was to assess students' perspective on the achievement of the educational objectives of the Community Oral Health and Periodontology Departments using the CIPP model of evaluation.
Materials and Methods: A cross-sectional survey has been conducted using a questionnaire consists of four domains as introduced in the CIPP model of evaluation (Context, Input, Process and Product). Two groups of senior dental students of the dental school of Tehran University of Medical Sciences were approached. Data was collected anonymously and was analyzed with non-parametric Mann-Whitney test using the SPSS statistical package.
Results: The response rate was 67.7% for year 6 and 87.5% for the year 5 students. Respondents considered material presented in Periodontology Department more relevant and in need for their future career. However, teaching skills and motivation of the educators in Periodontology Department was considered inadequate. 67% of students reported having problem with material taught in Periodontology Department. Overall, significant difference in domains of Context and Process was observed between two departments (p<0.05). In the output domain students rated their clinical and theoretical ability "weak" in relation to splint, implant, management of acute gingivitis and electrosurgery compared with other topics which rated "good". Students considered their ability in using the principals of Evidence-Based Dentistry moderate.
Conclusion: The evaluation of the educational achievements of the two departments (COH and Periodontics) using CIPP model of evaluation showed that there is significant difference in two domains (Context and Process). In those topics which achievement was reported weak the revision of teaching methods is recommended.

Abstract
Background and Aims: The increase in the number of complex implant cases has drawn the attention of researchers toward materials having bone regeneration promoting ability. Socket preservation and bone graft are recommended to minimize bone resorption. The aim of this study was to evaluate a kind of xenograft collagenic bone (osteo biol gen_oss) in socket regeneration.
Materials and Methods: This randomized clinical trial was performed in 12 cases (6 in test and 6 in control groups) with two hopeless teeth. After tooth extraction, in test group, graft material was put in sockets but in the control group the socket was healed naturally. Three months later, during implant placement the specimens from both sites were sent to a pathologist for histologic and histomorphometric evaluations. Data were analyzed using Mc Nemar and Wilcoxan sigh rank test (α=0.05).
Results: There were no significant differences between two groups in foreign body reaction, inflammation, bone vitality and percentage of bone gain. Average percentage of residual graft in test site was 6.73±1.43.
Conclusion: Osteobiol gen_oss xenograft is an appropriate biocompatible osteoconductive material that promotes bone regeneration at 3 months following socket preservation in human extraction sockets.

Abstract
Background and Aims: According to the importance of primary stability on dental implant success and osseointegration, we intend to check and compare the stability and crestal bone loss rate between osteotomy technique and conventional implant insertion techniques.
Materials and Methods: In this study, 26 implants in anterior segment of maxilla in 13 patients were evaluated. The implants were TBR system (Toulouse, France) with 3.5 diameter and 10.5-12 mm length. The implant stability level was recorded immediately after surgery and 3 months later with Ostell mentor. The periapical radiography was taken immediately after surgery, 3 and 6 months to assess crestal bone resorption. Paired t-test and Wilcoxon signed Rank test used for data analysis.
Results: There were no statistically differences between the two treatments techniques in terms of stability (P>0.05). The mean crestal resorption was higher for the osteotomy technique 3 months after implant insertion (P<0.001) but there were no significant differences after 6 months (P=0.678).
Conclusion: Within the limitations of the current study, it can be concluded that the osteotomy it can be considered as a treatment technique in insufficient bone width.
