Abstract Objective The purpose of this article was to analyze the effect of an instructional video on practical tutorial and to ascertain whether an instructional video improves students’ performance on practical performance and reduces the stress associated with learning. Materials and Methods A randomized controlled trial was conducted on a group of 78 first-year students. A pretest was conducted by administering questionnaires to evaluate the interest in the use of videos as well as the level of stress. Students were randomly assigned into two groups: control and test. Students assigned to the control group received conventional teaching, while the experimental group received both conventional teaching and watched a video. Thereafter, a satisfaction questionnaire was distributed to each of the groups, and they were awarded a grade. Results A total of 98.7% of students wished to learn fixed prosthodontics through instructional videos, as they believed that the videos could reduce their worry and stress levels. At the end of the first tutorial, the total grade was significantly lower for the test group (p = 0.003). However, the subjective value of stress was significantly lower in the test group (p = 0.0007) as well as the subjective value of tutorial difficulty (p = 0.0004). Students felt that they better understood the objectives of the tutorial “thanks to the video” (p = 0.0001). Conclusion This study did not reveal any improvement in terms of performance when an instructional video was used for tutorials in comparison with the conventional teaching method. However, the results show a reduction in the level of stress.

Abstract Background: The advent of electronic teaching facilities opened doors towards a better tutor-student communication. The aim of this study is to explore the effectiveness of phone-based ARS (PB-ARS) using text- and multimedia-based questions on information retention by male dental undergraduate students and to explore the students’ perception and acceptance of ARS. Methods: A cross-over clustered randomised control trial was conducted at the College of Dentistry, Prince Sattam Bin Abdulaziz University/Alkharj/ Saudi Arabia. Students were allocated to one of two event groups (G1 or G2) using computer generated randomization. During the first intervention (lecture 1), G1 received ARS assisted lecture and G2 acts as a control group, then crossed over during the second intervention (lecture 2). Data for short- and long-term information retention were treated on intention to treat analysis basis and tested using Mann–Whitney U and t-test in addition to qualitative assessment of students’ perception and acceptance. Results : The results showed marginal improvements in short and long term retention of information in addition to positive attitude of students towards the ARS system. 87.5% of students in ARS group showed an improvement in their quiz score compared to 79.3% for control group. No statistically significant differences were observed between the intervention and control groups. Conclusion : the ARS system could be considered as an adjunctive teaching method to improve on information retention and interest in Orthodontics taught materials.

Medicines Use Review

Abstract Background Based on several existing patient-oriented activities, Medicines Use Review (MUR) service was standardized and officially adopted in Slovenia in 2015. Service aims to provide adherence support and ensure safe and effective medicines use. Therefore, the aim of the study was to evaluate the benefits of MUR in Slovenia, primarily the impact on medication adherence. Methods A randomised controlled trial was performed in community pharmacies to compare MUR with standard care. Patients were randomised into either the test (patients received MUR by a certified MUR provider at visit 1), or control group. The study primary outcome was self-reported adherence to multiple medications, assessed by electronic ©Morisky Widget MMAS-8 Software at the first visit (V1) and after 12 weeks (V2). A sub-analysis of intentional and unintentional non-adherence was performed. MUR impact was defined as the relative difference in ©MMAS-8 score after 12 weeks between the test and control group. A multiple linear regression model was used to predict MUR impact based on baseline adherence (low versus medium and high). Several secondary outcomes (e.g. evaluation of drug-related problems (DRPs)) were also assessed. Results Data from 153 (V1) and 140 (V2) patients were analysed. Baseline adherence was low, moderate and high in 17.6, 48.4 and 34.0% patients, respectively. In the low adherence subpopulation, test group patients showed a 1.20 point (95% CI = 0.16–2.25) increase in total ©MMAS-8 score (p = 0.025) compared to control group patients. A 0.84 point (95% CI = 0.05–1.63) increase was due to intentional non-adherence (p = 0.038), and a 0.36 point (95% CI = − 0.23-0.95) was due to unintentional non-adherence (p = 0.226). Additionally, statistically significant decrease in the proportion of patients with manifested DRPs (p < 0.001) and concerns regarding chronic medicines use (p = 0.029) were revealed. Conclusion MUR service in Slovenia improves low medication adherence and is effective in addressing DRPs and concerns regarding chronic medicines use.

High blood pressure, diabetes, hyperlipidemia and obesity are risk factors for cardiovascular diseases. With regard to the significant role of a healthy diet in the prevention and even treatment of diseases together with the high cost and side effects of drugs, finding foods effective in the treatment of metabolic disorders has been widely considered. This study aimed to evaluate the effect of oxymel – an Iranian traditional syrup with vinegar base – on cardiovascular risk indicators in obese and overweight people. Candidates were selected based on a set of inclusion criteria and were divided into two groups of control and test. The control group received 250 cc of water, while the test group received 250 cc water containing 30 cc of the oxymel for 30 days. Anthropometric and biochemical indicators were measured at the beginning and end of the study. The results showed that there were no significant changes in the body mass index, waist circumference, hip circumference, waist to hip ratio, HDL, LDL, Triglycerides, systolic and diastolic blood pressure, and blood glucose level. However, weight (P = 0.053) and cholesterol (P = 0.083) decreased relatively significantly in the test group compared to the control group. This study shows that consumption of oxymel has positive cardiovascular effects such as lowering the blood cholesterol level and can contribute to weight loss; however, studies with a larger sample size are recommended.

Abstract Background Poor oral hygiene and high hormone levels during pregnancy can lead to a deterioration in periodontal health. This study assessed the effectiveness of a family-centered behavioral and educational counselling program on improving the periodontal health of women during pregnancy and postpartum. Methods A randomized controlled trial was conducted among pregnant women (10th-22nd gestational week) and their husbands. Participating families were randomized into test and control groups. Intervention in the test group included explanation of oral health education (OHE) pamphlets, oral hygiene instruction, individualized feedback, and proposed solutions to overcome barriers in self-care. Reinforcements were implemented in the 3rd trimester of pregnancy and six months postpartum. In the control group, only OHE pamphlets were distributed. The assessed outcomes were bleeding on probing (BOP), periodontal pocket (Poc), loss of clinical attachment (LoA), and Visible Plaque Index (VPI). The data collection was carried out at baseline (T0), in the 32nd gestational week (T1), and 12 months postpartum (T2). Results Altogether 589 pregnant women were recruited, and 369 attended all three visits (test:188; control:181). In the test group, the mean VPI score at T0 was 0.19, which decreased to 0.14 at T1 and 0.15 at T2. In the control group, the mean VPI decreased from 0.19 at T0 to 0.16 at T1, but increased to 0.22 at T2. A main effect of time and intervention and an interaction between time and intervention were detected (all p < 0.05), indicating that the intervention effect differed between T1 and T2. The test group showed a significantly greater decrease over time than the control group did. Similarly, the mean BOP% decreased more significantly over time in the test group (T0:57%, T1:46%, T2:35%) than in the control group (T0:58%, T1:52%, T2:46%). For Poc and LoA, there were improvements in both study groups at 12 months postpartum, compared with during pregnancy (p < 0.001). Conclusions Providing family-centered, behavioral, and educational counselling to pregnant women at an early stage of pregnancy and with reinforcements can improve their oral hygiene and reduce gingival inflammation. The effect can be sustained over an extended period and is greater than that of distributing oral health leaflets alone. Trial registration Clinicaltrials.gov, #NCT02937194.

The aim of this randomised, double blind controlled trial was to verify the efficacy of a herbal dentifrice on the reduction of plaque and gingivitis. Forty eight volunteers with established gingivitis were randomly assigned to either a test group (herbal dentifrice) or positive control group (dentifrice with triclosan and fluoride). The dentifrices were distributed in plain white tubes by an independent pharmacy, which revealed the contents of each tube only after the experimental period. Plaque and gingivitis assessments were carried out on baseline and after 28 days of product use. All examinations were conducted by the same calibrated investigator. Subjects were instructed to brush their teeth three times daily using their assigned dentifrice for 28 days. There was a significant reduction in plaque levels in both the test and control groups. However, there was no significant difference between the groups. A significant reduction in gingivitis was observed in both groups, although there was no significant difference between them. No adverse reactions were reported. The authors concluded that both dentifrices were effective in reducing plaque and gingivitis in subjects with established gingivitis.

IntroductionSputum smear microscopy is the cornerstone of tuberculosis (TB) diagnosis under the Revised National Tuberculosis Control Programme (RNTCP) in India. Instructions on how to produce a good sputum sample are a part of RNTCP training manuals, but its assessment is not emphasised. Healthcare provider’s instruction to expectorate a good sputum sample has limitations. Presumptive TB patients often submit inadequate (in quantity and/or quality) sputum samples, which may result in false-negative results. Objectives of the study are, among the selected RNTCP designated microscopy centres inDakshina Kannadadistrict, Karnataka, India, (a) to assess the effectiveness of mobile phone instructional video demonstrating sputum expectoration on sputum quality and quantity and (b) to explore the mobile phone video implementation challenges as perceived by the healthcare providers.Methods and analysisThis is a pragmatic, prospective, non-randomised controlled trial in two pairs of RNTCP Designated Microscopy Centres (located at secondary and primary healthcare facilities) ofDakshina Kannadadistrict, India. Presumptive pulmonary TB patients aged ≥18 years will be included. We will exclude who are severely ill, blind, hearing impaired, patients who have already brought their sputum for examination, and transported sputum. In the intervention group, participants will watch a mobile phone instructional video demonstrating submission of an adequate sputum sample. The control group will follow the usual ongoing procedure for sputum submission. This study would require 406 participants for each group to achieve a power of 90% for detecting a difference of 15% between the two groups. The participant enrolment started in December 2019.Ethics and disseminationYenepoya University Ethics Committee, Mangaluru, India, has approved the study protocol (YEC-1/158/2019). It complies with the Declaration of Helsinki, local laws, and the International Council for Harmonization-good clinical practices. Investigators will present the results in scientific forums, publish in a scientific journal, and share with RNTCP officers.Trial registration numberClinical Trial Registry of India (CTRI/2019/06/019887).

Summary Objective The aim of this study was to investigate the effects of piezocision (surgical protocol with sutures) in orthodontic treatment using CAD/CAM (computer-aided design and computer-aided manufacturing) customized orthodontic appliances. Design The study is designed as a parallel group, randomized controlled trial (RCT). Setting University Hospital. Ethical approval The study was approved by the ethic committee of the University Hospital Liege, Belgium. Subjects and methods This RCT was conducted on 24 adult patients requiring orthodontic treatment to release mild overcrowding. Patients were all treated with a customized appliance and randomly assigned by means of sealed envelopes containing group codes to either a test group treated with piezocision or a control group without any further treatment. A blinded orthodontist validated appliance removal or further adjustments based on the model study. Outcome measures The overall treatment time and the time between archwire changes were recorded. Moreover, clinical and radiological features such as tooth resorption, gingival recessions, and the presence of scars were evaluated. Results A total of 24 patients (12 control and 12 test) completed the study. The overall treatment time was significantly shorter in the test group than the control group. Likewise, the time difference between all arch changes was significantly lower when piezocision was performed, except for the first arch at the mandible and the last arches at both maxillae. During the fine-tuning phase, no significant difference was found between the two groups. All periodontal and radiographic parameters remained stable from the start to the end of treatment in both the groups. However, minor scars were found in 66 per cent cases. Limitations This trial was a single-centre trial. Conclusions Piezocision seems to be an effective method to accelerate orthodontic treatment in cases of mild overcrowding. However, the effect was only observed during the alignment phase and a greater efficiency was found in the maxilla. The technique may be contraindicated in patients with a high smile line since the risk of slight scarring exists. Registration ClinicalTrails.gov (Identifier: NCT03406130)

Abstract Background Layering techniques for direct composite resin restorations might be complicated for inexperienced learners, as a number of materials and instruments are required at each step. The present study aimed to compare and assess the teaching effect of step-by-step and all-in-one teaching methods in layering techniques for direct composite resin restorations among undergraduate dental students. Methods A total of 68 junior dental students participated in this study, which was a prospective and single-blind trial. The students were randomly divided into a step-by-step group (experimental group, n = 34) and all-in-one group (control group, n = 34). The same teacher taught the two groups, ensuring a comparable teaching effect. The final score of each student was an average of scores by two experts who were blinded to the grouping. The scoring system was consisted by five parts. Each part was assigned scores of 3.0, 1.5, or 0. The total maximum score was 15 and minimum was 0. The total time taken by each group was also calculated. Results The values of the quality of tooth restorations evaluated by experts for step-by-step and all-in-one groups were 11.29 ± 2.13 from 15 and 9.00 ± 2.71 from 15 (t = 3.88, P < 0.001), respectively. In addition, the time spent by the experimental group was significantly lesser than that spent by the control group, which was 122.47 ± 2.82 and 137.18 ± 6.75 min, respectively (t = 11.72, p < 0.001). Conclusion With regard to the layering techniques for direct composite resin restorations, the outcomes were better in the step-by-step group than in the all-in-one group.

A serious outbreak of staphylococcal infections in the maternity units in Blackburn was investigated. There were considerably more than one hundred cases of breast abscesses altogether, well over half of which occurred in primiparae. Staphylococcus aureus, phage type 80, was the predominating organism throughout the outbreak and at the peak period during the early part of the outbreak this type was responsible for nearly 80% of the infections.After the introduction of a number of procedures for the general reduction of cross-infection the incidence of breast abscess fell markedly and a controlled trial of an antibacterial cream, containing neomycin and hibitane, which was applied to the nasal mucosa of all infants and mothers in the test group of patients, was undertaken. The conditions obtaining in the test and control groups were identical in every way except that the control patients did not receive the neomycin-hibitane cream. There were about 1250 mothers and infants each in the test and control groups; the incidence of breast abscesses in the test group was 0·8% and in the control group it was 2·7%. The method adopted for the detection and treatment of carriers among the nursing staff broke down on two occasions; this fact and the emergence of an unforeseen source resulted in a larger number of infections than should have occurred. Had it not been for these incidents there is little doubt that the trial would have shown more conclusively the effectiveness of the neomycinhibitane cream, by the method laid down, in reducing cross-infection.Investigation of the bacterial flora on the nasal mucosa of over 1000 infants in the control group yielded results of considerable interest. Of 300 cases where there was early colonization by Staph. albus, this organism established its dominating position in 70% of the cases and it was not subsequently displaced by Staph. aureus. The significance of this observation and the evidence favouring nasal dissemination of Staph.aureus as the most important cause of hospital cross-infection are discussed.
