ABSTRACT Objectives To evaluate the effect of fixed orthodontic treatment on periodontal parameters in periodontally compromised adult orthodontic patients. Materials and Methods This was a prospective, randomized, controlled clinical trial. Thirty-six periodontally compromised adult patients (mean age: 29.67 ± 4.8 years) were randomly allocated to either test (perio-ortho) or control group (perio). After periodontal stabilization in both groups, orthodontic treatment was started in the test group, whereas the control group remained on periodontal maintenance only. Evaluation and comparison of clinical parameters (plaque index [PI]; gingival index [GI]; bleeding on probing [BOP]; probing depth [PD]; clinical attachment level [CAL]) of both groups was assessed at three time intervals: T0 (base line), T1 (at start of orthodontic treatment), and T2 (1 year after start of orthodontic treatment). Radiological parameters (alveolar bone levels [ABL]) were recorded using CBCT at T1 and T2. Results Intragroup analysis showed statistically significant improvement in all clinical and radiological periodontal parameters in both groups (P ≤ .05). Intergroup comparison revealed improvement in the periodontal parameters was not statistically significant between the groups (P ≥ .05). Subgroup analysis showed reduction in the number of moderate and severe periodontitis sites in both groups with significant more gains in ABL in the test group compared to the control group. Conclusions Orthodontic treatment after periodontal stabilization does not have any detrimental effect on periodontal health in adult periodontally compromised orthodontic patients and may add to the benefits achieved by periodontal treatment alone.

The aim of this study was to compare the efficacy of dental plaque removal by brushing with and without conventional dentifrice. Twenty-four students aged 17 to 28 years participated in this randomized controlled clinical trial. Quadrants 1-3 or 2-4 were randomly allocated to the test group (brushing without dentifrice) or control group (brushing with dentifrice). After 72 h of cessation of oral hygiene, Quigley & Hein (Turesky) plaque index was assessed before and after brushing by a calibrated and blind examiner. Overtime and intergroup comparisons were performed by Student's paired sample t-test at 5% significance level. The results showed that both groups after toothbrushing presented statistically significant reductions in plaque, with no differences between them (from 3.06 ± 0.54 to 1.27 ± 0.26 versus from 3.07 ± 0.52 to 1.31 ± 0.23). A separate analysis of the buccal and lingual aspects also showed no significant differences between groups. It may be concluded that the use of a conventional dentifrice during toothbrushing does not seem to enhance plaque removal capacity.

Abstract Objectives The aim of this randomized controlled clinical trial was to compare the clinical outcomes obtained in intrabony defects following regenerative periodontal surgery using the single-flap approach (SFA) in conjunction with either hyaluronic acid (HA) or enamel matrix derivative (EMD). Materials and methods Thirty-two intrabony defects in 32 healthy subjects were randomly assigned: HA (test group) or EMD (control group). Clinical attachment level (CAL), probing depth (PD), gingival recession (REC), and bleeding on probing (BOP) were recorded at baseline,12, 18, and 24 months after surgery. Results At 24 months, both treatments resulted in statistically significant clinical improvements evidenced by PD-reduction and CAL-gain (p<0.001). The mean CAL-gain was 2.19±1.11 mm in the test and 2.94±1.12 mm in the control sites (p=0.067). PD-reduction was statistically significantly higher for the control group (4.5±0.97 mm) than the test group (3.31±0.70 mm), (p=0.001). CAL-gain ≤ 3 mm was observed in 87.5% and in 62.5% of the test and control sites, respectively. Test sites showed slightly lower REC values than the control sites. No statistically significant differences were found for BOP between treatments. Conclusions The present findings indicate that both treatments led to statistically significant clinical improvements compared to baseline, although the application of EMD resulted in statistically significantly higher PD-reduction compared to the use of HA. Clinical relevance The use of HA in conjunction with a SFA resulted in significant PD-reduction and CAL-gain, pointing to the potential clinical relevance of this material in regenerative periodontal surgery.

Abstract Background Premature birth can affect maternal mental health. Considering that the mental health disorder in mothers may play a vital role in the growth and development of their children, therefore, this study was conducted to determine the effect of supportive counseling on mental health (primary outcome), mother-child bonding and infant anthropometric indices (secondary outcomes) in mothers of premature infants. Methods This randomized controlled clinical trial was carried out on 66 mothers with hospitalized neonates in the NICU of Alzahra hospital in Tabriz- Iran. Participants were randomly allocated into two groups of intervention (n = 34) and control (n = 32) through a block randomization method. The intervention group received 6 sessions of supportive counseling (45–60 minutes each session) by the researcher, and the control group received routine care. Questionnaires of Goldberg General Health and the postpartum bonding were completed before the intervention (first 72 hours postpartum) and 8 weeks postpartum. Also, the anthropometric index of newborns were measured at the same time. Results There was no statistically significant difference between the two groups in terms of socio-demographic characteristics. After the intervention, based on ANCOVA with adjusting the baseline score, mean score of mental health (AMD: -9.8; 95% Confident Interval (95% CI): -12.5 to -7.1; P < 0.001) and postpartum bonding (AMD: -10.0; 95% CI: -0.6 to 13.9; P < 0.001) in the counseling group was significantly lower than those of the control group; however, in terms of weight (P = 0.536), height (P = 0.429) and head circumference (P = 0.129), there was no significant difference between the two groups. Conclusions Supportive counseling may improve mental health and postpartum bonding in mothers of premature infants. Thus, it may be recommendable for health care providers to offer it to mothers.

AbstractImportanceVagus nerve stimulation via slow-paced breathing could serve as adjuvant therapeutic approach to reduce excessive inflammation in coronavirus disease 2019 (COVID-19) pneumonia.ObjectiveDoes a slow-paced breathing technique increasing vagal activity reduce Interleukin-6 (IL-6) in patients hospitalized with moderate COVID-19 pneumonia compared to standard care?DesignSingle-center randomized controlled clinical trial with enrolment from February 23rd 2021 through June 17th 2021 and follow-up until July 22nd 2021.SettingWard for infectious diseases and temporary COVID-19 ward, Ulm University Hospital, GermanyParticipantsConsecutive sample of patients hospitalized with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and moderate COVID-19 pneumonia (primary diagnosis). Of 131 patients screened, 48 patients were randomized and 46 patients analyzed (N=23 per group).InterventionsSlow-paced 20-minute breathing exercise three times a day with six breaths per minute (inhale-to-exhale ratio 4:6).Main outcomes and measuresDifferences between intervention and control group in IL-6 calculated using multilevel mixed-effect linear regression models with random slope including the covariates relevant comorbidities, COVID-19 medication, and age.ResultsMean age 57 years±13 years, N= 28 (60%) male, N=30 (65%) with relevant comorbidities. The model including group by time interaction revealed a significantly lower trajectory of IL-6 in the intervention group compared to the control group (effect size Cohens f2=0.11, LR-test p=.040) in the intention-to-treat sample, confirmed by treatment-per-protocol analysis (f2=0.15, LR-test p=.022).Exploratory analysis using the median split of practice time to predict IL-6 of the next morning indicated a dose-response relationship with beneficial effects of practice time above 45 minutes a day.Three patients in each group were admitted at ICU, one died. Oxygen saturation increased during slow-paced breathing (from 95.1%±2.1% to 95.4%±1.6%, p=0.006).Conclusion and relevancePatients practicing slow-paced breathing had significantly lower IL-6 values than controls without relevant side effects. Further trials should evaluate clinical outcomes as well as an earlier start of the intervention, i.e., at symptom onset. This would offer an access to a therapy option not only for high-income, but also for low- and middle-income countries.Trial registrationGerman register of clinical trials (ID: DRKS00023971) https://www.drks.de, Universal Trial Number (UTN) U1111-1263-8658;Key pointsQuestionCan slow-paced breathing reduce Interleukin-6 (IL-6) in hospitalized patients with moderate coronavirus disease 2019 (COVID-19) pneumonia?FindingsSingle-center randomized controlled clinical trial including 46 patients hospitalized with moderate COVID-19 pneumonia. Compared to controls, IL-6 values were significantly lower (small-to-medium effect sizes) in patients who were instructed to practice six breaths per minute for 20 minutes three times a day. More minutes of slow-paced breathing were significantly correlated with lower IL-6 values the next morning.MeaningSlow-paced breathing could be a safe and feasible adjuvant therapeutic approach in moderate COVID-19 pneumonia.

Abstract Background: Preterm infants have a low level of bone mineralization compared to those born at term, since 80% of calcium incorporation occurs at the end of pregnancy. The purpose of the present study was to investigate the effect of reflex locomotion therapy on bone modeling and growth in preterm infants and to compare its effect with those of other Physiotherapy modalities.Methods: A multicentre randomized controlled clinical trial was conducted (02/2016 – 07/2020). 106 preterm infants born at the Virgen de la Arrixaca University Clinical Hospital, the General University Hospital of Elche and the Torrecárdenas Hospital in Almería, between 29 and 34 weeks with hemodynamic stability, complete enteral nutrition and without any metabolic, congenital, genetic, neurological or respiratory disorders were evaluated for inclusion. Infants were randomly assigned to three groups: one group received reflex locomotion therapy (EGrlt); another group received passive mobilizations with gentle joint compression (EGpmc); and the control group received massage (CG). All treatments were carried out in the neonatal units lasting one month. The main outcome measure was bone formation and resorption measured with bone biomarkers. A mixed ANOVA was used to compare the results of bone biomarkers, and anthropometric measurements. Results: Infants were randomized to EGrlt (n = 38), EGpmc (n = 32), and CG (n = 36). All groups were similar in terms of gender (p = 0.891 female 47.2%), gestational age (M = 30.753, SD = 1.878, p = 0.39) and birth weight (M = 1413.45, SD = 347.36, p = 0.157). At the end of the study, significant differences were found between the groups in their interaction in bone formation, measured with osteocalcin [F (2,35) = 4.92, p = 0.013, ηp2 = 0.043], in benefit of the EGrlt. Conclusions: Reflex locomotion therapy has been effective in improving bone formation, more so than other Physiotherapy modalities. Therefore, reflex locomotion therapy could be considered one of the most effective physiotherapeutic modalities for the prevention and treatment of osteopenia of prematurity Trial registrstion: Trial retrospectively registered at ClinicalTrials.gov.

The properties of the biodegradation of bone substitutes in the dental socket after extraction is one of the goals of regenerative medicine. This double-blind, randomized, controlled clinical trial aimed to compare the effects of a new bioabsorbable nanostructured carbonated hydroxyapatite (CHA) with a commercially available bovine xenograft (Bio-Oss®) and clot (control group) in alveolar preservation. Thirty participants who required tooth extraction and implant placement were enrolled in this study. After 90 days, a sample of the grafted area was obtained for histological and histomorphometric evaluation and an implant was installed at the site. All surgical procedures were successfully carried out without complications and none of the patients were excluded. The samples revealed a statistically significant increase of new bone formation (NFB) in the CHA group compared with Bio-Oss® after 90 days from surgery (p < 0.05). However, the clot group presented no differences of NFB compared to CHA and Bio-Oss®. The CHA group presented less amount of reminiscent biomaterial compared to Bio-Oss®. Both biomaterials were considered osteoconductors, easy to handle, biocompatible, and suitable for alveolar filling. Nanostructured carbonated hydroxyapatite spheres promoted a higher biodegradation rate and is a promising biomaterial for alveolar socket preservation before implant treatment.
