Abstract
Background and Aim Periodontal diseases are among the most prevalent inflammatory diseases caused by oral bacteria. Expansion of oral biofilm causes various diseases such as gingival inflammation and periodontitis. The Satureja plant has various species, all of which are aromatic. This plant is traditionally used for the treatment of some diseases. The present study was conducted to evaluate the effect of Satureja essential oil on periodontal pathogens.
Methods and Materials In this study, we evaluated four pathogens; Enterococcus faecalis, Streptococcus sanguinis, Eikenella corrodens, and Actinomyces viscosus. We also used the disk diffusion test and broth microdilution method to evaluate the antimicrobial effect of Satureja essential oil. Finally, we determined the minimum inhibitory concentration and minimum bactericidal concentration.
Ethical Considerations The Ethics Committee of Arak University of Medical Sciences approved this study (Code: IR.ARAKMU.REC.1397.67).
Results In concentration of 0.1 g/mL of Satureja plant, Actinomyces viscosus, Streptococcus sanguinis, Enterococcus faecalis, and Eikenella corrodens were found to be sensible to resistance. The Satureja essential oil had the highest effect on Eikenella corrodens. Results obtained from the biofilm test showed no biofilm in a concentration of 12.5 mg/mL and higher of Satureja plant.
Conclusion The Satureja plant was found to have an antibacterial and inhibitory effect on biofilm growth and formation in the oral cavity.

Abstract
Background and Aim: Periostin acts as necessary protein in tissue development and has a key role in tooth-supporting tissues such as periodontal ligament. The effect of inflammation on reducing periostin level has been shown in some studies. The aim of this study was to compare the salivary and Gingival Crevicular Fluid (GCF) periostin levels in patients with chronic periodontitis and healthy peers.
Methods & Materials: In this matched case-control study, 106 participants (53 patients with chronic periodontitis and 53 healthy controls) were studies after signing a informed consent form. They were matched for age, gender, weight, and Body Mass Index (BMI). The GCF and salivary samples were collected from all participants and were assessed using standard Enzyme-Linked Immunosorbent Assay (ELISA). The statistical analysis was conducted in Stata V. 11.
Ethical Considerations: This study was approved by the Research Ethics Committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1397.34).
Results: The salivary and GCF periostin levels was significantly lower in patients than in healthy subjects (P<0.001). Moreover, the periostin levels was significantly different based on periodontal parameters (P<0.001).
Conclusion: There is association between the incidence of chronic periodontitis and salivary and GCF periostin levels. Hence, the periostin may act as a potential biomarker for the diagnosis of chronic periodontitis and prevention of its progression.

Abstract
Background and Aim: Although there are methods such as the use of mouthwashes to prevent periodontal diseases, these diseases are still the most common oral diseases. Given the side effects of chemical methods, the present study aimed to evaluate the inhibitory and antibacterial effects of peppermint essential oil on periodontal pathogens.
Methods & Materials: Antibacterial effect of the peppermint essential oil by the disk diffusion and Microplate dilution techniques was performed on 4 standard bacteria purchased from the microbial bank of Iran, including Enterococcus Faecalis, Streptococcus Sanguinis, Eikenella corrodens, and Actinomyces Viscosus. The minimum inhibitory concentration and minimum bactericidal concentration of the essential oil were also evaluated. The amount of biofilm formation was obtained by calculating the average biofilm formation in the three wells and comparing it with the optical density of negative control by the Elisa Reader device.
Ethical Considerations: This study was approved by the Research Ethics Committee of Arak University of Medical Sciences with code: IR.ARAKMU.REC.1397.15.
Results: Results of diffusion test showed the inhibitory effect of 0.1 g/mL essential oil on Enterococcus Faecalis and Streptococcus Sanguinis. Pure essential oil of peppermint showed the strongest inhibitory effect on streptococcus sanguinis followed by enterococcus faecalis, actinomyces viscosus and eikenella corrodens.
Conclusion: The peppermint plant has antibacterial and inhibitory effects on the bacteria of enterococcus faecalis, streptococcus sanguinis, eikenella corrodens, and actinomyces viscosus. Therefore, peppermint as a natural and effective antibacterial agent, has a potential application in the prevention of periodontal disease.

Abstract
Background and Aim: Chronic periodontitis is the most prevalent form of periodontitis and it generally considered as a progressive inflammatory disease. Environmental and systemic factors can alter the immune response to biofilm and lead to progressive degenerative disease. Chronic periodontitis is defined as an infectious disease that causes inflammation in the tooth-supporting tissues, periodontal attachment loss, and bone loss. Identification of risk factors for this disease is important. Hence, this study aims to evaluate the risk factors for chronic periodontitis.
Methods & Materials: This case-control study was conducted on 120 periodontitis patients and 120 healthy controls in Arak, Iran. A questionnaire was used to estimate their Socio-Economic Status (SES) and survey demographic and risk factors. For the diagnosis of chronic periodontitis, the identification of plaque accumulation site and clinical examination were performed. To investigate the association of chronic periodontitis with study variables, multilevel logistic regression analysis was used in STATA V. 11 software.
Ethical Considerations: This study obtained its ethical approval from the Research Ethics Committee of Arak University of Medical Sciences under code: 1397.145.
Results: The Odds Ratio (OR) of chronic periodontitis in adults aged above 30 years was 2.91 (95% CI: 1.01-8.73). Compared to subjects with low SES, the OR of chronic periodontitis was 2.28 (95% CI: 1.22- 4.27) in those with moderate SES and 0.89 (95% CI: 0.79-0.98) in those with high SES. Compared to patients who did not brush their teeth, the OR of chronic periodontitis was 0.67 (95% CI: 0.39-0.89) in patients reported toothbrushing. Compared to those who reported changing toothbrush sooner than 3 months, the OR was 4.96 (95% CI: 2.27-11.3) in those their changed their toothbrush for more than 6 months interval. The OR of chronic periodontitis in current smokers was 3.09 (95% CI: 1.52-4.76).
Conclusion: Cigarette smoking, alcohol consumption, tooth brushing, and SES are the risk factors associated with chronic periodontitis.

Abstract
Background and Aim: Considering the increasing use of dental implants in replacing lost teeth, the odds of failure over time in this treatment are inevitable, as with other dental treatments; thus, it requires careful and regular follow-up. Accordingly, the present study aimed to evaluate the awareness and attitude of general dentists about the follow-up of the dental implants to create baseline information to schedule future workshops concerning dental implants.
Methods & Materials: In this analytic cross-sectional study, 98 general dentists of Arak City, Iran were evaluated. Questionnaires were designed in 3 sections, as follows: demographic, awareness, and attitude. After checking the validity and reliability of the questionnaires, they were distributed among the research participants. The obtained data were analyzed using descriptive analysis, Chi-squared test, and Independent Samples t-tests. The significance level was considered 0.05.
Ethical Considerations: This article was approved by the Ethics Committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1397.283).
Results: The average score of awareness of the questionnaires was equal to 10.8 (based on the score of 0-19); the mean score of attitude was measured as 12.8 (based on the score of 7-21). Fifty-Three of the explored dentists had performed implant treatment, whose awareness and attitude toward implants follow-up were significantly higher than those of the dentists who did not perform such treatment (P=0.0001). Work experience presented no significant effect on the examined dentists’ awareness and attitude (P>0.05).
Conclusion: General dentists have low awareness and attitude about implant follow-up. Follow-up plays an important role in the long-term success of implant therapy; therefore, dental education/retraining programs should be reviewed in this field.

Abstract
Background and Aim: Different implant angulation, which is unavoidable in clinical situations, can affect the accuracy of impression. The aim of this study was to investigate the effect of fixture position on the accuracy of connecting impression coping to implants with internal hex.
Materials and Methods: A gypsum model with 4 implants with internal hex connection was prepared. The implants were installed in different mesiodistal angles of 0, 15, 25 and 35 degrees to the longitudinal axis in the gypsum model. To simulate the gums, a gingival mask was injected around the implants to a height of 2 mm. After a training session for senior dental students on how to close the impression coping, forty students were asked to close the impression copings on four implants. The correctness of the impression coping was evaluated by an expert prosthodontist. Data were statistically analyzed using Cochran Q test. Significance level was considered 0.05.
Ethical Considerations: this article is approved by ethics committee of Arak University of Medical Sciences.
Findings: The correct performance of students in connecting the impression coping to the implant at angles of 0, 15, 25 and 35 degrees was equal to 85%, 72%, 52%, 35%, respectively. With the exception of 0 and 15 degree groups, a statistically significant difference was observed between different study groups.
Conclusion: The fixture position has a significant effect on the accuracy of connecting impression coping to the implants with the internal hex and by increasing the implant angulation, the accurate connection the impression coping to the implant decreases.

Abstract
Introduction: Dental unit water lines (DUWL) are a potential place for the accumulation of microorganisms and the formation of microbial biofilm, which exposes people to infection risk. This study aimed to investigation of the effectiveness of four commonly used substances and selection of most effective disinfectant in DUWLs disinfection.
Methods: This systematic review study was conducted based on PRISMA templates and the PubMed, Scopus and Web of Science databases with a specific search strategy were examined. In this systematic review study, the effectiveness of 4 disinfectants including: hydrogen peroxide, chlorhexidine, chlorine-dioxide, sodium hypochlorite on microbial biofilms in the DUWL was investigated. The study was conducted on July 10, 2021, and finally the data of all studies related to the subject of this systematic review were extracted. This study was approved by the Research Ethics Committee at Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1399.347).
Results: All four disinfectants in sufficient concentration and time can be useful and effective. If the biofilm in DUWL is old and stabilized, it will affect the effectiveness of these materials and it will take longer to remove.
Conclusions: The use of materials in combination can cover all the microbial spectrum present in the biofilm of this area, and even fixed biofilms can be removed with extended and continuous use.
