Objective: To compare two fluorinated varnishes for the control of white spot lesions.Material and Methods: A randomized controlled clinical trial was conducted. A total of 103 active whitespot lesions on permanent upper anterior teeth from 24 patients, aged 7 to 9 years were randomly assigned totwo groups, G1: Duraphat® (n=52) and G2: DuraShield® (n=51). Weekly applications were perform for fourconsecutive weeks. Fifth week the dimension, regression and activity of the lesions were evaluated. Student’sT test, Wilcoxon Ranks and Chi square were used at 5% significance. Results: At the end of the study, the lesion reduction was observed in 69.7%, finding significant differences(p<0.05) in the mean of the initial and final dimensions in general (2.74 mm to 1.91 mm) and in each group, G1(2.84 mm to 2.03 mm), G2 (2.64 mm to 1.78 mm). In the activity of the lesions, it was found in the G1, 12 active and6 inactive lesions; while in G2, there were 14 active and 29 inactive; these differences were significant (p<0.05). Conclusions: The two evaluated products showed similar clinical efficacy in the remineralization of activewhite spot lesions after 4 weeks of therapy.

Background. Moderate-to-severe pain is reported in up to 75% of the patients in the first 48 hours after cardiac surgery. Evidence suggests that distraction is an effective nursing intervention for controlling short-term and transient pain. Distraction can be achieved by various techniques, including progressive muscle relaxation, meditation, and rhythmic breathing (RB). The present research aimed at evaluating the impacts of RB on the severity of sternotomy pain after Coronary Artery Bypass Graft (CABG). Methods. This randomized, controlled clinical trial was conducted on 60 patients after CABG surgery at the open-heart surgery Intensive Care Unit (ICU) of Kowsar Hospital, affiliated to Semnan University of Medical Sciences in Semnan, Iran. The patients were selected through convenience sampling and randomly assigned to two groups, including (1) intervention or RB and (2) control groups. RB was performed in the intervention group every 12 hours (9 a.m. and 9 p.m.) for three consecutive days after the surgery. The control group received only routine care for pain control (opioid analgesics) with no additional interventions. The severity of pain was measured every day in both groups of patients before and after the interventions using the Visual Analog Scale (VAS). Results. The mean postintervention pain scores were significantly different from the mean preintervention scores in the intervention group ( p  < 0.05). The changes in the mean pain score in the intervention group were also significantly different from the corresponding changes in the controls ( p  < 0.05). Conclusion. Based on the results, the severity of pain after the intervention was significantly lower in the RB group compared to the control. RB was found to be an effective technique for reducing the patients’ pain and is therefore recommended as a post-CABG pain control technique. Iranian Registry of Clinical Trials: this trial is clinically registered with IRCT20120109008665N7, registered 3 September 2018.

A total of 199 patients were selected for a comparison of the anti-dandruff efficacy of four shampoos. After a 2-week lead-in (all patients used only Johnson's Baby Shampoo twice weekly) the patients were randomly assigned to Selsun Blue®, Head & Shoulders®, Flex®, or Tegrin®. The test preparation, which was unknown to the observer, was used twice weekly for 4 weeks. Loose and adherent dandruff were each rated on a scale of 0 to 20 (absent to severe) at the end of the lead-in (when a total score of 15 was required), and each week of study. The mean total pre-study score for all subjects was 19.5. At the end of the study the mean improvement scores were: 162 (Selsun Blue), 14.6 (Head & Shoulders), 13.5 (Flex), and 13.1 (Tegrin). The improvement was significantly greater (p < 0.05) on Selsun Blue than on any of the other shampoos. At the end of the study significantly (p < 0.05) more patients had total scores of zero on Selsun Blue (15) than on Tegrin or Head & Shoulders. In addition, the rate of improvement was significantly (p < 0.05) faster with Selsun Blue than with any of the other test preparations.

Introduction: Hemorrhoid is one of the most common anorectal diseases which affects 5% of the general population. Complications and pain are inevitable after all surgeries with different intensities and degrees.Management and control of these complications is one of the most important aspects of postoperative care. There are surgical techniques and interventions for the treatment and control of pain after hemorrhoid. According to the contradictory results of the studies on surgical methods, the present study aimed to compare the effectiveness, complications, and safety of hemorrhoidectomy with Ligasureand Ferguson hemorrhoidectomy. Methods: The study sample in this randomized controlled clinical trial studyincluded54 patientswhowere randomly divided into two groupsofLigasureandFerguson surgery. Prior to the surgery, patients were educated abouttheVisual Analogue Scale(VAS).Patients underwent general anesthesia and the same surgeon performed the surgery in both groups. Immediately after the surgery (oncethe patient regainedconsciousness and understoodthe environment), 6, 12, and 24 hours after the surgery, patients’ pain and complications were assessed.The collected data were analyzed using SPSS software (version 18)through independent t-test, Mann-Whitney, Friedman, Chi-square and Fisher’s exact test at a significance level of α=0.05. Results: The mean bleeding during the surgery was significantly lower in the Ligasuregroupthan the Ferguson group. The mean pain at 0, 6, 12, and 24 hafterthe surgery was not significantly different between the two groups.Postoperative complications were significantly higher in the Ligasuregroup than the Ferguson group. Conclusion: Ligasurehemorrhoidectomy is not superior to the Ferguson method in terms of analgesia up to 24 h after the surgery; however, this method of surgeryis preferable to the Ferguson method in terms of bleeding during the surgery.

Aim of the study: This RCT assesses patients’ 18-month clinical outcomes after the regenerative therapy of periimplantitis lesions using either an electrolytic method (EC) to remove biofilms or a combination of powder spray and an electrolytic method (PEC). Materials and Methods: Twenty-four patients (24 implants) suffering from periimplantitis were randomly treated by EC or PEC followed by augmentation and submerged healing. Probing pocket depth (PPD), Bleeding on Probing (BoP), suppuration, and standardized radiographs were assessed before surgery (T0), 6 months after augmentation (T1), and 6 (T2) and 12 (T3) months after the replacement of the restoration. Results: The mean PPD changed from 5.8 ± 1.6 mm (T0) to 3.1 ± 1.4 mm (T3). While BoP and suppuration at T0 were 100%, BoP decreased at T2 to 36.8% and at T3 to 35.3%. Suppuration was found to be at a level of 10.6% at T2 and 11.8% at T3. The radiologic bone level measured from the implant shoulder to the first visible bone to the implant contact was 4.9 ± 1.9 mm at mesial sites and 4.4 ± 2.2 mm at distal sites at T0 and 1.7 ± 1.7 mm and 1.5 ± 17 mm at T3. Conclusions: Significant radiographic bone fill and the improvement of clinical parameters were demonstrated 18 months after therapy.

Abstract Background: We aimed to study the effectiveness of a “celiac” smartphone application on gastrointestinal symptoms in celiac patients. Methods: In the present randomized controlled clinical trial, 60 celiac patients were randomly assigned to receive education through a smartphone application (n=30) or conventional clinical education (n=30). We assessed the gastrointestinal symptoms using the gastrointestinal symptom rating scale (GSRS) questionnaire at baseline and three months after interventions. The GSRS total score, celiac disease GSRS (CD-GSRS) score, abdominal pain, reflux, diarrhea, constipation, and indigestion scores were calculated. Results: Out of 60 randomized patients, 58 patients completed the study. In comparison to baseline, the mean score of GSRS total score (p=0.04), CD-GSRS score (p=0.001), and indigestion subscore (p<0.001) were significantly decreased in the intervention group. In the control group, compared to baseline, the mean scores of CD-GSRS score (p=0.03) and abdominal pain subscore (p=0.04) were significantly reduced; and the mean score of reflux (p=0.01) subscore was significantly increased. The results of the between-group comparisons showed that although the mean GSRS and CD-GSRS total scores were lower in the intervention group compared with the control group, the differences were not statistically significant. In terms of GSRS subscores, there was a significant difference between the two groups only in the mean score of indigestion (P=0.01).Conclusion: According to the results, smartphone application had a significantly positive effect on indigestion symptoms compared with routine clinic education. However, more large studies with longer duration of the follow-up period are needed to assure this approach Trial registration: The protocol of the study was registered in the Iranian registry of clinical trials (IRCT code: IRCT20170117032004N2). trial registry webpage: : https://www.irct.ir/user/trial/40187/view.

Abstract Background: We aimed to study the effectiveness of information provided via smartphone application on gastrointestinal symptoms in patients with celiac disease (CD).Methods: In the present randomized controlled clinical trial, 60 patients with CD were randomly assigned to receive education through a smartphone application (n=30) or conventional clinical education (n=30). The patients were asked to use it for obtaining the required information for three months. We assessed gastrointestinal symptoms using the gastrointestinal symptom rating scale (GSRS) questionnaire at baseline and three months after interventions. The GSRS total score, celiac disease GSRS (CD-GSRS) score, abdominal pain, reflux, diarrhea, constipation, and indigestion scores were calculated.Results: Out of 60 randomized patients, 58 patients completed the study. The mean age of the participants was 37.49±9.32 years, and the mean disease duration was 4.57±3.36 years. There were no significant differences between the two groups regarding the baseline values. In comparison to baseline, the mean CD-GSRS score (p=0.001) and indigestion subscore score (p<0.001) were significantly decreased in the intervention group. The results of the between-group comparisons showed that although the mean GSRS and CD-GSRS total scores were lower in the intervention group than in the standard care group, the differences were not statistically significant. In terms of GSRS subscores, there was a significant difference between the two groups only in the mean score of indigestion (P=0.002).Conclusion: According to the results, using smartphone application for providing information to patients with celiac disease had only a significant positive effect on indigestion symptoms compared with routine clinic education, and we did not observe any significant differences in GSRS and CD-GSRS scores between the two groups.Trial registration: The protocol of the study was registered in the Iranian registry of clinical trials (IRCT code: IRCT20170117032004N2). trial registry webpage: https://www.irct.ir/user/trial/40187/view.

Background: Acupuncture has shown benefit in preventing migraine attacks, but there has been no clear recommendation about the number of treatment sessions that should be provided. Objectives: The aim of this study was to examine whether 5 sessions of acupuncture treatment is non-inferior to 10 sessions for migraine. Methods: We performed a multicenter, open-label, randomized, controlled clinical trial across five hospitals in Thailand. Migraine patients were randomly assigned into two groups: treatment with 5 sessions of acupuncture (group A) or 10 sessions of acupuncture (group B). Acupuncture was performed twice a week. We measured the number of migraine days, average pain severity according to a 0–10 numeric pain rating scale (NPRS) and quality of life using the EQ-5D-5L questionnaire, comparing 4 weeks after treatment versus baseline. Results: Of 156 patients, 83 and 73 patients were assigned to groups A and B, respectively. Comparing 4 weeks after treatment with baseline, the mean reduction in the number of headache days in groups A and B was 6.4 (95% confidence interval [CI] 4.8 to 7.9) days and 6.4 (95% CI 4.5 to 8.4) days, respectively (p = 0.97). The mean difference between the reduction in headache days of the two groups was −0.1 (95% CI −2.5 to 2.4) days, which included the pre-specified non-inferiority limit of −1. The mean reduction of NPRS scores in groups A and B was 4.5 (95% CI 3.8 to 5.1) and 3.8 (95% CI 3.1 to 4.5), respectively (p = 0.17). Both groups showed an improvement in quality of life. Conclusion: Both 5 and 10 sessions of acupuncture were associated with apparent benefits in terms of preventing migraine attacks, reducing the severity of the headache and improving quality of life, based on comparisons between baseline and follow-up in both study groups. Although we were unable to demonstrate non-inferiority of 5 sessions versus 10 sessions of acupuncture, the effects in the two groups were not significantly different and the temporal effects appeared to last for at least 1 month.
