Background and Aim:Malocclusion has an important effect on patients' social behaviors and mental situation and might affect their oral health-related quality of life (OHRQoL). The aim of this study was to assess OHRQoL in patients attending orthodontics department of Isfahan Azad University. Materials and Methods:The present descriptive study was conducted on 77 patients in need of orthodontic treatment applying a census sampling method. Before entering the treatment phase, volunteer patients filled out Oral Health Impact profile-14 (OHIP-14) questionnaire. Index of Orthodontics Treatment Need (IOTN): Aesthetic Component (AC) and Dental Health Component (DHC) were used to assess patient's orthodontic treatment need. Student's t-test, Mann-U-Whitney test, analysis of variance, kruskal wallis test, pearson and spearman correlation coefficient, and linear regression model served for statistical analysis. Results:The mean score of OHIP was 14.1 (±8.9, range 0-35). Orthodontic treatment need was high or very high among 65% of the participants based on DHC. Based on AC, 33.8% of patients reported definite need to orthodontic treatment. A significant association existed between OHIP and DHC (r=0.28, P=0.017), and between OHIP and AC (r=0.24, P=0.036); however, it was weak. Based on linear regression model, OHIP was significantly associated with education (P=0.026) and AC of IOTN (P=0.026). Conclusion:Although, the relationship between malocclusion and OHRQoLin the present study was week, it is recommended for orthodontist to consider the effects of oral problems on patients' quality of life, in addition to their professional methods in diagnosis and treatment planning.
Introduction: Since orthodontic removable appliances might be infected with fungi and bacteria, they need to be cleaned using natural disinfectants and chemicals. This study aimed to compare the clinical impact of thyme essence and Fluconazole solution on the amount of Candida albicans colonies and Streptococcus mutans accumulated on the removable appliances in orthodontic patients. Materials & Methods: In this descriptive-analytical study, 21 patients were selected who used the wear Hawley’s retainer for 24-hours. Patients were divided into three groups of seven. One group first washed the plaque with soap and water and then spray thyme essence all over it at a 5-centimeter distance (4 times on each side). In the other group, as before, the plaque was washed and from the same distance as before, the fluconazole solution (10 mg/ml) was sprayed on all surfaces 4 times. In the control group, the retainer was washed every night only with soap and water. After one month, the retainers were delivered form patients. The two samples were then separated from the Kami platelets and sent to a laboratory for microbial culture. Data were analyzed by Mann-Whitney, T-test (α = 0.05). Results: The use of thyme essence increases the mean area of Candida albicans inhibition, which was significantly higher than that in the control group (p value = 0.03). The effect of Fluconazole solution on this mean area )Candida albicans inhibition zone( was not significant compared to that observed in the control group (p value = 0.5). In the group in which thyme essence was used, the mean area of Streptococcus mutans inhibition, which was significantly higher than that in the control group (p value = 0.05). When Fluconazole solution was used, the mean area of Streptococcus mutans inhibition, was not significant compared to that observed in the control group (p value = 0.071). Conclusion: Compared to Fluconazole solution, thyme essence functions more effectively in increasing Candida and Streptococcus mutans inhibition zones.
Introduction: Most orthodontists believe that orthodontic treatment does not cause TMD (Temporomandibular disorder), although some disagree with this. The aim of this study was to evaluate the prevalence of symptoms of temporomandibular joint disorders in class II skeletal patients in three groups with a history of orthodontic treatment, orthosurgery and no treatment Materials and Methods: In this descriptive-analytical study, 99 adult skeletal patients of class II referred to the orthodontic department of Khorasgan in 2020 were selected. The prevalence of TMD was assessed in three subgroups: recipient of orthodontic treatment without orthosurgery, recipient of orthodontic treatment with orthosurgery treatment, and not receiving orthodontic treatment. Anamnestic and Dysfunction indices were assessed using Helkimo index and questionnaire. Data were analyzed by Kruskal-Wallis and Chi-square and Fisher's exact test (p value < 0.05). Results: There was no significant difference in the severity and prevalence of TMD in adults with class II malocclusion among the three groups when comparing the anamnestic index and dysfunction index among patients with orthodontic treatment, orthosurgery and without treatment (p value < 0.05). In the examination of TMD in adults with class II malocclusion div1 and div2 among the three groups, there was no significant difference among patients with orthodontic treatment, orthosurgery and without treatment when compared with the anamnestic index and dysfunction index (p value < 0.05). Conclusion: Severity and prevalence of TMD in adults with Class II malocclusion were no different in the three groups.
