Introduction: As the oral health related quality of life has been important in many dental patients GOHAI is an acceptable tool, preparing its Persian version can be useful in oral health research among Persian populations. The aim of this study was to evaluate the reliability and validity of the Persian version of General Oral Health Assessment Index (GOHAI).
Methods: Translation was performed using the forward-backward process. The final Persian version was then tested through an interview and test-retest to evaluate its comprehensibility and reliability. A sample of 150 subjects (20-65 years old) was requested to answer the GOHAI items prior to a clinical examination.
Data on the subjects’ socio-demographic characteristics and self-rating report of oral health, general health and dental care needs were recorded. Internal consistency was calculated by Cronbach’s α. Interview and test-retest reliability was evaluated by weighted kappa. Concurrent validity was assessed by comparing GOHAI scores and self-rated measures of oral health, general health and perceived dental care needs. Discriminant validity was tested by comparing GOHAI scores with clinical oral condition.
Results: The mean GOHAI score was 46.78±7.85. Cronbach’s α (0.78) showed a high internal consistency and homogeneity between items. Weighted kappa coefficient for the interview varied from 0.60 to 0.96 and was between 0.33 and 0.64 for test-retest. Bland-Altman plot displayed a good agreement between the two GOHAI scores for both the interview and test-retest. There was no significant relationship between GOHAI scores and self-rating oral health (p=0.090), but there was a relationship between self-rating general health and mean GOHAI scores (p=0.047). Also, the low GOHAI scores were associated with the perceived dental care needs (p=0.001). There was an opposite correlation between GOHAI scores and caries and missing teeth (p<0.0001).
Conclusions: The Persian version of the GOHAI exhibits acceptable reliability and validity, so it can be used widely throughout the persian communities.

Introduction : Previous researches showed that neutral soaps significantly increased bond strength and decreased microleakage of dentin bonding agents. The aim of this study was histopathological evaluation of the effect of sodium sulfonate application as neutral soap on the cat's dental pulp after an ideal composite restorative treatment .
Methods: Ten adult cats with 40 caries-free canine teeth were selected for the study. Class V cavities were prepared in the buccal surfaces of all the teeth. The teeth of the right quadrants were treated with composite, whereas the teeth of the left quadrants were primarily etched, after using of sodium sulfonate solution, they treated with composite. The first five cats were killed after one week and the other five cats after one month. The teeth were fixed, decalcified and after being sliced, paraffined blocks were made and microscopic slides were prepared and histologically evaluated.
Results: The results of the histological evaluation showed that there were no statistically significant differences between the intensity of inflammation in the pulp of the teeth in the right and left quadrants after one week (P=1.000) and one month (P=0.773). However, there was significant difference after one week regarding predentin formation (P=0.017) and in the teeth of the left quadrants, the formation of predentin was more that the right quadrants, but no meaningful difference was observed after one month (P=0.203).
Conclusion: It seems that the sodium sulfonate in composite restorative treatments without fear of damage to the pulp can be used.

Introduction: The measurement precision of jaw is important for surgery or installing implants. Preimplant radiographs are important part of clinical evaluations before implant surgery. For choosing location, we should consider the important anatomical structures like mental foramen, inferior alveolar canal, nasal cavity and maxillary sinus.It is important to know the measurement accuracy of radiographic techniques. The purpose of this study was to compare mandibular vertical linear measurement in panoramic and tomography images.
Methods: Three forms of mandible from dry adult human skulls were used in this study (triangle, square and ellipse). For each mandible, surgical stent was made using transparent with gold standard.acryl. A thin tube was placed in the stents in three regions (incisors, premolars and molars) to set gutta-percha. Then, the panoramic view and conventional tomography were obtained. Four oral and maxillofacial radiologists measured the vertical dimension in panoramic and conventional tomography. Finally, each mandible was sectioned in the marked sections and was measured by a digital caliper (gold standard) and compared with conventional tomography and panoramic view .The obtained data was analyzed using SPSS18 software and student t-test, Pearson correlation coefficient and non parametric Mann-Whitney Test.
Results: The mean difference between the panoramic and gold standard linear vertical dimension values in premolar and molar regions was above 1mm and above 2mm in incisor region. The mean difference between conventional tomography and gold standard measurements in all three regions was 1mm.
Conclusions: The linear measurement of vertical dimension in conventional tomography was more precise than panoramic. The use of a 2.0 mm safety margin in the evaluation of implant sites was recommended.In incisor area, the other radiography methods like CBCT was suggested.

Introduction: Cytokines are the important factors in the progression of periodontal diseases. The aim of this study was to find out the effect of the first phase of the periodontal therapy on the amount of existing IL-17 and IL-23 in gingival crevicular fluid in patients with severe periodontitis and in the control group.
Methods: In this clinical trial intervention study,after purifying the parts which were under consideration in 22 patients with severe periodontitis, gingival crevicular fluid was gathered using periopaper located within the gingival sulcus, Then, the first phase of periodontal therapy was carried out and sample taking from the same parts was conducted after 4 weeks. The same phase was carried out on 24 healthy patients (control group). All patients were selected from the Department of Periodontology, Tehran Islamic Azad University Dental Branch. Since the data did not have a normal distribution, therefore, nonparametric tests were used for comparing the groups (Mann-Whitney U Test). A p≤0.05 is considered as significant.
Results: The results showed that there was a meaningful and significant difference between the IL-17 viscosity before (p<0005) and after (p<005) the therapy and IL-23 viscosity before (p<0001) and after (p<001) the therapy between the two groups.
Conclusions: According to the results of the present study, we can conclude that IL-17 and IL-23 have a significant role in the pathogeneses of periodontal disease.

Introduction: Cigarette smoking has been recognized to be a risk factor for progression of periodontal disease . Due to less inflammation and bleeding in the presence of clinical signs of periodontal disease in smokers than in nonsmokers and given the conflicting results of studies on changes in the epithelium and gingival connective tissue by smoking, this study was performed to evaluate the thickness and keratosis on the epithelium of free and sulcular gingival tissue in smokers and nonsmokers patients with moderate to advanced periodontitis.
Methods: In this cross sectional study, biopsies were obtained from palatal gingival of 60 patients with moderate to advanced periodontitis (30 smokers and 30 nonsmokers). These biopsies were histologically processed, serially sectioned at 5 microns, stained with H. E., and examined by image analysis software (analysis- SL- starter), which was used to perform the morphometric evaluation of the outer and inner epithelial thickness, keratosis and vascularity in connective tissue. The data were analyzed with SPSS 17, t -test, Mann-Whitney Test, and Pearson correlation. P < 0.05 was considered significant.
Results: Histopathological examination showed significant association between smoking and CAL (P=0.048), keratosis on outer epithelium (P=0.020) and mean of thickness of outer (P=0.023) and inner (P< 0.001) marginal gingival epithelium but gingival vascular density in nonsmokers was more than smokers (P=0.002). Collagenized connective tissue was observed in smokers more than non smokers . (P< 0.001)
Conclusion: It seems that the reduction of the clinical signs of inflammation in the gingival tissue of smokers is due to changes in gingival epithelium and connective tissue from smoking.

Introduction: The selection of porcelain is based on high biocompatibility, endurance, superficial texture and aesthetics. Nevertheless, the innate fracture charateritics of porcelain is the main cause of the intra oral fractures. Electing a suitable porcelain restorative system in terms of stability of color is important. For this reason, this study aimed to examine the color changes of common porcelain repair materials .
Methods: Using a silicon mold, 30 pieces of feldspathic porcelain in A3 color, 10mm of diameter and 2 mm of thickness were prepared. The samples were randomly distributed into three groups :
Group 1: Porcelain-Silane-Bonding-Composite
Group 2: Porcelain-Silane-Bonding-Panavia F 2.0-Bonding-Silane-Porcelain
Group 3: Porcelain-Silane-Bonding-Choice 2 -Bonding-Silane-Porcelain
The aging process was accomplished with thermocyling (3000 cycles, 5/55 degree), incubation in 37° and 100° humidity. Thereafter, discoloration was assessed In CIE system via designation of color transforming matrix in MATLAB environment .
Results: The average quantitative amount of discoloration at day 0, 90 and 180 were 76.8±0.57, 79.15±0.52, 80.13±0.6 for Choice, 78.03±0.9, 79.42±0.82, 80.17±0.51 for Panavia, and 78.41±1.53, 79.59±0.77, 81.03±0.63 for Composite, respectively. The color changes by the time were significant for the all three groups (p<001).Calculating day 0-180 color changes, mean color differences for Choice, Panavia and Composite groups were 3.33±0.83 , 2.13±1.23, and 2.61±1.6, respectively. The color changes did not differ in the studied groups (p<0.133).
Conclusions: Post-aging color changes were significant, although all samples had color changes less than 3.5,Considering the clinical significance of color changes of more than 3.5, these results were acceptable and all three restorative materials could reliably be applied in the daily clinical use .

Introduction: The quality of life is defined as the individual's sense of well-being and their satisfaction with daily work as influenced by dental and oral conditions. Oral diseases are very common and have impacts on the different aspects of individual's life and can change their social performances roles, in other words, they can change the quality of life. The aim of this study was to evaluae the impact of oral problems on quality of life in adults who referred to Babol Faculty of Dentistry during 2009-2011.
Methods: This cross-sectional study was performed using a non-randomized sampling method. In this study, 500 patients who referred to Babol Faculty of Dentistry age 20-50 years were selected. Then all the questions in OIDP (Oral Impact on Daily Performance) questionnaire which were translated into persian from english were asked and completed. These questions are valuable and reliable for Iranians based on the previous studies. Finally, the data were analyzed by SPSS statistical software.
Results: According to this study, oral problems have effected on (80.6%) of the patients’ quality of life. Gender, occupation, level of education and general health have impacted on OIDP score changes. There were significant differences in gender, occupation and level of education. In this study, the general and oral health conditions scores showed a significant association with OIDP score. Most of the patients’ complaint was about eating (64.4%), but going outside and shopping were the least (10%).
Conclusions: According to the results of this study, tooth pain was the most oral and dental problem and tooth shape and size were the least effective on the oral health related quality of life. This shows that the most needed treatment are tooth restoration ، root canal therapy and surgical treatment for pain relief.
