Background and Aim Parental acceptance is an important parameter in selecting the proper behavior management technique during pediatric dental treatment. The present study aimed to compare the effects of different informing methods on acceptance of parents about behavior management techniques used in pediatric dentistry. Methods & Materials This quasi-experimental study was conducted on one 162 parents of 3-7-year-old uncooperative children who were candidates for dental treatment. They were randomly divided into three groups. Their acceptance about six behavior management techniques including general anesthesia, voice control, hand-over-mouth, parental separation, active and passive physical restraint were assessed by a questionnaire. After determining the level of acceptance, the information about the techniques was presented through three ways include writing, verbal and visual methods. Finally, their acceptance of each technique and the reasons for non-acceptance were re-evaluated. Data were analyzed in SPSS v.23 software using ANOVA and t-test. Ethical Considerations This study obtained its ethical approval from the Research Ethics Committee of Arak University of Medical Sciences under code: IR.ARAKMU.REC.1398.102. Results The informing methods significantly increased the parents’ acceptance about behavior management techniques. According to the ANOVA results, the effect of visual presentation method in general anesthesia technique was significantly lower than that of other methods (P<0.05), while its effect in active physical restraint technique was significantly greater than that of other methods (P<0.05). There was no statistically significant difference between the effects of informing methods in other behavior management techniques. Conclusion Informing parents about pediatric behavior management techniques increase their acceptance. Informing by visual presentation is the most effective method for increasing their acceptance of physical restraint technique, while in their acceptance of general anesthesia technique other informing methods are more effective.

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 FROM AUTHOR]
