ABSTRACT Objectives To compare canine retraction using NiTi closed coil springs vs elastomeric chains comprehensively in a split-mouth randomized controlled trial. Materials and Methods The canines in 64 quadrants were randomly retracted into the first premolar extraction spaces using NiTi closed coil springs or elastomeric chains, in the maxilla and mandible. The retraction force was 150 g. Cone beam computed tomography scans and study models were obtained before the start of canine retraction and 6 months later. The rate and total amount of canine retraction, canine rotation, tipping, and root resorption were evaluated. A visual analogue scale was used to evaluate patients' pain experience. Results The two methods were statistically similar for dental changes, rate of canine retraction, and root resorption. However, patients reported significantly more days of pain with the elastomeric chain compared to the NiTi closed coil springs. Conclusions Within the constraints of the current study, using either NiTi closed coil springs or elastomeric chains as force delivery systems for canine retraction results in no significant difference in the rate of canine retraction, tipping, rotation, or root resorption. Pain experience during retraction using elastomeric chains is more significant yet needs further investigation.

Introduction: The objective of the study was to assess the rate of canine retraction and secondary outcomes associated with conventional fixed orthodontic treatment (CFO) and CFO with micro-osteoperforation (CFO + MOP), that is, anchorage loss, root resorption, vitality of tooth, pain and discomfort level during the procedure. Methods: A total of 16 patients with Class II Division 1 malocclusion who required upper first premolar extraction with lower non-extraction/single incisor extraction were divided into the test group (MOP) and positive control group (CFO + MOP) for a split-mouth study. Both maxillary canines were retracted with nickel–titanium (NiTi) closed coil springs. Patients were reviewed after 24 hours, 7 days, 28 days, and 4, 8, and 16 weeks to assess the rate of tooth movement, anchorage loss, root resorption, vitality of tooth, pain and discomfort level. Results: There was a statistically significant difference in the rate of tooth movement between the CFO and CFO + MOP groups after the first 4 weeks ( P-value = .026), whereas no statistically significant difference was observed at 8, 12, and 16 weeks ( P-value = .33, .99, and .08, respectively). In the CFO group, there was no statistically significant difference in tooth movement between different time intervals ( P-value > .05). There was no significant difference in root resorption between the groups. The pain level was higher in the MOP group in the first 24 hours ( P-value < .05) after the procedure. Later on, the difference in pain level between the groups was not significant ( P-value > .05). The vitality of retracted canines in both groups was healthy. Conclusion: The study recommends that the CFO + MOP procedure has substantial potential to be used as an adjunct to the routine mechanotherapy for faster tooth movement, as it may reduce the treatment time by half in the first 4 weeks after the MOP procedure. There are no potential differences in anchorage loss, tipping, vitality, and apical and lateral root resorption between the CFO and CFO + MOP groups. This trial was registered at Clinical Trial Registry, India.

Objective: This study was conducted to compare the efficacy of 3Mixtatin (a combination of simvastatin and 3Mix antibiotic) with MTA and Formocresol for the pulpotomy of primary molars. Study design: 114 children aged 3–6 years old with 150 primary molars were randomly allocated to three groups. MTA, Formocresol or 3Mixtatin were used for Pulpotomies. Hard setting zinc oxide eugenol was used to cover these materials. The teeth were restored with amalgam. Blinded radiographic and clinical examinations were conducted at 6, 12 and 24 months after treatment for the presence of pain, tenderness to palpation and percussion, sinus tract, swelling, presence of internal or external root resorption, inter-radicular radiolucency, and periapical lesion. Results: 122 teeth were available for 24-month follow-up study. The overall success rate was 78.9% for FC, 90.5% for 3Mixtatin and 88.1% for MTA group. There was no significant difference in overall success rate among the groups after 24-month follow-up (X2=2.43, df = 2, P =0.27). Conclusion: Our findings demonstrated remarkable results of 3Mixtatin in pulpotomy of primary teeth at the 24-month follow-up. Therefore, 3Mixtatin may be considered as an effective material in pulpotomy of primary teeth because of its successful results.

Abstract Background: Preoperative information about pain has been shown to improve postoperative pain perception and reduce postoperative analgesia requirements. However, there is limited data regarding the effect of preoperative counselling in low resource settings. This study aimed at assessing the effect of preoperative information about pain on postoperative pain experience measured as postoperative pain using a verbal numerical rating scale (VNRS) and patient satisfaction with pain management. Methods: A randomised, double blind, controlled trial was done in Mulago National Referral Hospital (MNRH), Kampala. We prospectively enrolled 400 participants aged 18years and above scheduled for elective orthopaedic surgery. The consented patients were randomised to either receive the specific preoperative information about pain or not. The primary end points were postoperative pain score and patient satisfaction. A total of 340 were analysed with 170 in either arm. Secondary analyses where done to determine the factors that were associated with postoperative pain and patient satisfaction.Results: In both arms, the lowest pain score was 0/10 at 0 hours and the highest was 7/10 at 12 hours. A statistically significant difference between the intervention and control arms for the median pain score at 48hours (4/10 vs. 5/10) P-value= 0.029 was seen but none at 0, 12, 24hours. There was no difference in satisfaction with pain management (P value=0.059). Conclusion: Preoperative information about pain improves postoperative pain experience and may negatively impact patients’ satisfaction with pain management due to unmet expectations.Trial registration: Clinicaltrials.gov, NCT03056521.

ABSTRACT Background and Objectives New studies have been published and aimed to retract canines by means of distraction osteogenesis to reduce treatment time. Although a great care has been given to achieve a bodily movement of the canines, a significant amount of tipping of the canines has been observed. This trial aimed to assess the effect of applying a modified distractor on canine angulation. Materials and methods The sample of the study consisted of 14 canines in seven patients (16–25 years). After the osteotomy procedure, two distractors were applied (one distractor on each side). After 5 days of a latency period, the two distractors were activated at a rate of 1 mm/day. Results There was a significant difference between the two distractors regarding the time required to retract the canines (p = 0.008) and the observed change in canine angulation following retraction (p = 0.028). The change in the overjet and the mandibular plane angle was statistically insignificant. Eight out of 14 distracted canines reacted positively to the pulp vitality tester after 3 months of completion of distraction. There was no clinical sign of discoloration or pulpal pain in any canine. Conclusion Within the limits of this study, the modified distractor caused a bodily movement of the canine with a minimal tipping. Further research is required on a long-term basis on a larger group of patients to gain more insight on the observed changes.

Abstract Background The role of injectable platelet rich fibrin (i-PRF) in orthodontic treatment has not been investigated with focus on its effect on dental and bony periodontal elements. Objective To evaluate the efficacy of i-PRF in bone preservation and prevention of root resorption. Methods A randomized split-mouth controlled trial included 21 patients aged 16–28 years (20.85 ± 3.85), who were treated for Class II malocclusion with the extraction of the maxillary first premolars. Right and left sides were randomly allocated to either experimental treated with i-PRF or control sides. After the leveling and alignment phase, the canines were retracted with 150gm forces. The i-PRF was prepared from the blood of each patient following a precise protocol, then injected immediately before canine retraction on the buccal and palatal aspects of the extraction sites. Localized maxillary cone beam computed tomography scans were taken before and after canine retraction to measure alveolar bone height and thickness and canine root length (indicative of root resorption), and the presence of dehiscence and fenestration. Paired sample t-tests and Wilcoxon signed rank tests were used to compare the changes between groups. Results No statistically significant differences in bone height, bone thickness were found between sides and between pre- and post-retraction period. However, root length was reduced post retraction but did not differ between sides. In both groups, postoperative dehiscence was observed buccally and palatally and fenestrations were recorded on only the buccal aspect. Conclusions I-PRF did not affect bone quality during canine retraction or prevent canine root resorption. I-PRF did not reduce the prevalence of dehiscence and fenestration.

ABSTRACT Objective:  To compare pain experience between self-ligating and conventional preadjusted edgewise appliance systems with a two-arm parallel trial. Materials and Methods:  A prospective multicenter randomized controlled clinical trial was conducted in three hospital orthodontic departments. Subjects were randomly allocated to receive treatment with either a self-ligating (3M SmartClip™) or conventional (3M Victory™) bracket system with stratification for operator and center. Standardized protocol was followed for bracket bonding procedure and archwire sequence. Subject pain was recorded using a Verbal Rating Scale to assess discomfort felt on the teeth and soft tissues at the time of the appointment and 1, 3, and 5 days after each archwire change up to the working archwire. Multilevel modeling was used to analyze the data by blinded assessors. Results:  One hundred thirty-eight subjects (mean age 14 years 11 months) were enrolled in the study, of which 135 subjects (97.8%) completed the study and 113 (82%) returned the required data regarding pain/discomfort. Perceived pain was statistically higher with the SmartClip™ system compared to the Victory™ system, but this difference was not deemed to be clinically significant. Discomfort was greatest after placement of the initial 0.014-inch nickel-titanium archwire, compared with subsequent wires, and was greatest on day 1, less on day 3, and much less on day 5 after each archwire change. Age and gender did not affect the level of discomfort experienced by subjects undergoing fixed appliance treatment. Conclusion:  No clinically significant difference in pain experience was found between patients treated with a self-ligating bracket system compared to those treated with a conventional ligation system.

The Impact

Scientific research into the reduction of stigmatization, particularly related to specific problems such as Obsessive-Compulsive Disorder (OCD), is scarce. In the present study, we examine the impact of a video-based antistigma intervention program for OCD in a pretest-posttest control group research. After being randomly assigned to either an intervention (n= 101) or control group (n= 96), the participants reported their attitudes on a hypothetical case vignette before and after OCD vs. Multiple Sclerosis (MS) videos, and again six months later as a follow up assessment. The mixed design analyses for the group comparisons indicated that although there was no significant difference in the measures of the control group, the participants watching the anti-stigma OCD video, in which the focus was psychoeducation and interaction strategies, reported significantly lower scores on social distances and negative beliefs for the case vignettes they read, and this difference was maintained six months later. Then, the present results indicate the effectiveness of our anti-stigma intervention program for OCD. Interventions to reduce stigmatization can also be viewed as effective tools for changing the attitudes of people toward OCD, although further research and applications are needed related to specific disorders if a longlasting impact is to be achieved.

Mother-infant attachment is an intimate, lasting and satisfying relationship that leads to better cognitive, emotional and social growth of the infant. The aim of this study was to determine the effects of breastfeeding training by role-play on mother-infant attachment behaviours. This research was a randomised clinical trial (parallel design). Inclusion criteria were: no history of mental disorders; ability to read and write the Persian language to complete the questionnaire; no history of drug and tobacco intake in primigravida women. The sample comprised 100 pregnant women (in 2 groups), selected through simple random sampling at healthcare centres. The researcher reviewed prenatal care registries of selected healthcare centres and extracted the names of pregnant women in their early third trimester. The data were imported into randomisation software. The control group received routine breastfeeding training, while the intervention group received routine training together with training through role-play. The data collection tool was the Maternal Behaviour Inventory Questionnaire. Consequently 75 samples were analysed in SPSS16. Independent t-tests and chi-square tests were used to examine the difference between the two groups. Results showed that the mean score of mother-infant attachment one week after delivery was significantly higher in the intervention group in comparison to that in the control group (p<0.001). No significant difference was observed between the two groups in maternal age, age of marriage, neonatal gender, maternal employment and education, number of parity, and number of abortions (P>0.05). Since breastfeeding training through role-play could affect mother-infant attachment, it is suggested that this type of training should be provided for pregnant women to promote mother-infant attachment and exclusive breastfeeding.

Background: Pain control is considered as the key issue in modern midwifery. Along with medical painkillers, reflexology is viewed as a non-medical and noninvasive method. Hence, we aimed to investigate the effect of reflexology on the intensity of pain and length of labor. Materials and Methods: In this clinical trial, participants included 240 Iranian primiparous women with term and singleton pregnancy. Having a 3-4 cm cervical dilatation once they visited the hospital. Through a convenient sampling method, they were selected and then randomly divided into two groups. In the intervention group, reflexology was performed, and the intensity of pain during the active phase of labor along with the length of labor in the active phase was measured by visual analog scale (VAS) and compared with the control group. Data were analyzed using descriptive statistics, t-test, and Mann-Whitney U-test. Result: Data analysis showed a statistically significant difference between the intensity of pain in the 5-7 and 8-10 cm dilatation in the two groups (P=0.01). Moreover, the labor length in the active phase was found to be significantly shorter in the intervention group (P<0.001). Conclusion: It appears that reflexology can lead to a reduction in the pain and length of labor. Therefore, through instructing this technique, a goal of midwifery, which is reducing labor pain and its length can be achieved. Keywords: Reflexology, Labor Pain, Labor Length, Primiparous Women

BACKGROUND Cancer is a chronic disease with an incident worldwide had been 24.5 million and 9.6 million deaths in 2017. Lung and colorectal cancer are the most common cancer for both sexes and according to national and international recommendations platinum-based chemotherapy is the reference adjuvant treatment. This chemotherapy can be moderately to highly emetogenic. Despite antiemetic therapy, chemotherapy-induced nausea and vomiting may persist. Moreover, cancer patient are increasingly interested in alternative and complementary medicines and express the desire that non-pharmacological treatments be used in hospitals. Among alternative and complementary medicines, foot reflexology decreases significantly the severity of chemotherapy-induced nausea and vomiting in breast cancer patients. OBJECTIVE The primary objective of the present study was to assess the benefits of foot reflexology as a complement to conventional treatments on severity of acute chemotherapy-induced nausea and vomiting in digestive or lung cancer patients. The secondary objectives assessed were the frequency and severity of delayed chemotherapy-induced nausea and vomiting, quality of life, anxiety, and self-esteem. METHODS The present study was conducted between April 2018 and April 2020 in French University Hospital. This is an open-label randomized controlled trial. Participants are randomized into two groups: 40 to interventional group (conventional care with foot reflexology) and 40 to control group (conventional care without foot reflexology). Foot reflexology sessions (30 minutes) are performed on an outpatient or inpatient. Eligible participants are patients with a lung or digestive cancer with indication for platinum-based chemotherapy. RESULTS The severity of acute nausea and vomiting was assessed with a visual analogue scale during the second cycle of chemotherapy. A significant increase of at least 2 points was observed for control group (20.6%, P = 0.01). Across all cycle, the foot reflexology group showed a trend towards less frequent delayed nausea (P=0.28), a significantly less frequent consumption of antiemetic drugs (P=0.04), and no significant difference for vomiting (P=0.99); there was a trend towards a perception of stronger severity for delayed nausea in the control group (P=0.39). According to quality of life and anxiety, there was no significant difference between the interventional group and the control group (P=0.32 and P=0.53 respectively). CONCLUSIONS In conclusion, the present study results indicated that foot reflexology decreased significantly the severity of acute nausea and consumption of antiemetic drugs in lung and digestive cancer patients. No side effects from foot reflexology have been noted. In order to better respond to a desire of patients for non-pharmacological treatments and CAMs to be used in hospitals to improve their care, the results of this study showed that foot reflexology seems to be a promising complement to conventional antiemetic drugs. To assess the performance of this intervention in routine practice, a larger study with several health care centers would be relevant with a cluster RCT. CLINICALTRIAL The present study registered with clinicaltrials.gov: NCT03508180 (28/06/2018) INTERNATIONAL REGISTERED REPORT RR2-10.2196/17232
