Abstract Background Fluctuations in pH of saliva during a prolonged treatment course influences the enamel demineralization progress, which is one of the complications of fixed orthodontic treatment. This randomized clinical trial aimed to evaluate and compare the short-term effects of stainless steel (SS) versus elastomeric (EM) ligatures on salivary pH in patients scheduled for fixed orthodontic treatment. Methods Seventy participants were enrolled in the study (54 female, 16 male) aged 19–36 years who met specific inclusion criteria. They were randomly selected and allocated into two equal groups through computer-generated randomization. All patients received fixed orthodontic treatment using conventional orthodontic brackets. Two commonly used archwire ligature methods were used: SS and EMs. An unstimulated (resting) salivary sample was collected before tying of the ligatures at T0 (baseline), 2 weeks, 6 (weeks), and 12 (weeks). Salivary pH was measured using a digital pH meter. The level of significance was set at p value < 0.05. Results The salivary pH level was stable between T0 and T1 (6.72 ± 0.14), then significantly and progressively increased from T1 to T2 (6.78 ± 0.13) and from T2 to T3 (6.81 ± 0.14) with (p < 0.05) in the SS group. In the EM group, the salivary pH level was significantly decreased in all follow-up periods; T0 (6.77 ± 0.16), T1 (6.72 ± 0.14), T2 (6.67 ± 0.13) and T3 (6.64 ± 0.13). Conclusion The EM ligatures showed a significant decrease in salivary pH to an unfavorable level, which increased the risk of enamel demineralization. Therefore, EMs as ligature material is preferably should not be recommended in patients with high caries index or inadequate oral hygiene. Trial registration ANZCTR.org.

Background: Allergic rhinitis (AR) is one of the most common diseases in the world and affects about 10-50% of the general population. Probiotics are live microorganisms that help the normal state of the intestine, and if prescribed correctly, they can stimulate the mucosal immune system to prevent inflammatory symptoms of allergy and atopy. The present study aims to investigate the role of probiotics in the treatment of AR when added to standard therapy as adjuvant agents. Materials and Methods: In this clinical trial study, 28 patients older than 15 years with AR randomly divided into probiotics and control groups. The probiotics group received standard therapy for AR accompanied by probiotic capsules every 12 hours for eight weeks, whereas the control group received standard therapy for AR with placebo capsules as the same protocol. Data were analyzed using SPSS Version 23 (IBM Corporation, Armonk, NY, USA) and, the P-value less than 0.05 was considered statistically significant. Results: In the probiotics group, 14.3% of patients had sneezing at the baseline, which significantly decreased to 4.6% (P<0.01). Also, the necessity for nasal and oral corticosteroids after treatment with probiotics in the probiotics group was less than the control group (P<0.01). Although cough, nasal discharge, conchae hypertrophy, and night sleep disorders reduced after treatment with probiotics, this reduction was not statistically significant between the two groups. Conclusion: Based on the results of this clinical trial, the use of probiotics had no significant effect on the outcome of patients with AR. [GMJ.2020;9:e1918]

Objective: The purpose of this study was to investigate the efficacy of (Pro Seal) sealant in preventing enamel decalcification in-vivo and compare its effect with fluoride varnish and unfilled sealant using atomic force microscopy. Materials and Methods: Eight orthodontic patients who were candidates for extraction of all first premolars for orthodontic treatment were recruited to this study. Thirty two premolars (upper and lower) were randomly divided into four groups (n=8) for each group, 4 maxillary and 4 mandibular); Control (no -treatment); Fluoride varnish, Unfilled sealant (Light Bond) and filled sealant (Pro-Seal). After two months the brackets were debonded and the teeth were extracted and prepared for Atomic force microscopic scanning. Each sample was scanned twice at two different scan areas 50 and 10µm at the buccal cervical third of the crown. Images were recorded with slow scan rate and resolution and the mean roughness height and total surface area were calculated for each scan area. Comparison between groups was performed using one way analysis of variance test with level of significance was set to be 0.05. Results: Pro Seal treated samples show the lowest roughness height and total surface area. Conclusion: Pro Seal was the most effective prophylaxis technique in preventing enamel demineralization during orthodontic treatment.

Background: Riluzole is a glutamate regulator and effective in treatment of neuropsychiatric conditions. Aims: We assessed riluzole for treatment of methamphetamine dependence. Methods: In this randomized, double-blind, placebo-controlled clinical trial, male outpatients with methamphetamine dependence who were 18–65 years old received either 50 mg riluzole ( n=34) or placebo ( n=54) twice daily for 12 weeks. Patients were excluded in case of comorbid serious medical conditions or neurologic disorders, comorbid psychiatric disorders other than methamphetamine dependence requiring specific treatment interventions, simultaneous positive urine test result for substances of abuse other than methamphetamine, smoking >3 days per week, simultaneous consumption of medications which are contraindicated or have interaction with riluzole. Results: Concerning primary outcomes, the cumulative mean number of attended weekly visits was higher in the riluzole arm compared with the placebo arm approaching a statistically significant difference (riluzole, median (range)=13.00 (2.00–13.00); placebo=4.00 (2.00–13.00); Mann-Whitney U=505.00, p-value=0.073), and the weekly measured rate of positive methamphetamine urine test results was significantly lower in the riluzole arm by the end of the study (riluzole=1 (5.00%), placebo=9 (45.00%), p-value=0.004). Patients in the riluzole arm experienced significantly greater improvement on all the craving, withdrawal, and depression measures regarding mean score changes from baseline to endpoint. No significant difference was detected between the two arms in terms of incidence of adverse events. Conclusion: Future randomized clinical trials are needed to investigate proper dosing strategy in a more inclusive sample.

Abstract Background: Polycystic ovarian syndrome is the most common endocrine disorder in reproductive aged women. As a result of side effect of pharmaceutical medications women are interested in using alternative medicines to treat. To determine the comparative effects of Ferula assa-foetida on androgenic hormone levels and ovarian features in patient with polycystic ovarian syndrome (PCOS). Methods: In this triple-blinded controlled clinical trial, 34 student participants were randomly divided in two groups. Intervention group received 100 mg of oleo-gum resin of Ferula assa- foetida, control group received oral paraffin (Placebo) twice daily for 3 months. The efficacy of this herbal medicines was measured after the 3-month intervention. Hormonal assay for evaluating Testosterone, DEHAS, Prolactin, TSH, FSH, LH levels and also trans abdominal ultrasound for evaluating ovarian volumes, number of follicles of both ovaries, and endometrial thickness. Were measured before and after the study. Results: In this study, significant changes in DEHAS and TSH level were observed (p value<0.03). The greatest reduction in the number of ovarian follicles was reported in the Ferula group (p value <0.00). Conclusion: Use of Ferula assa-foetida can be effected in decrease of DHEAS, TSH levels, and ovarian follicles number in young girls with PCOS.Trial registration: the Iranian Randomized Clinical Trial (IRCT2016040427207N1).url: https://www.irct.ir/trial/22343
