Abstract Background: Dental bleaching in traditional concentrations generates greater sensitivity. In this respect, new systems of lower concentration of hydrogen peroxide for tooth bleaching appeared, with color stability unknown over time. The aim of this study was to compare the change and stability of color with low-concentration (6%) hydrogen peroxide gel in an in-office bleaching setting relative to conventional 37.5% gel, including their effects on psychosocial and esthetic self-perception, after one year. Methods: Patients (n=25) were assessed at 12 months post bleaching treatment (whitening with 6% chemo-activated alkaline formula gel versus 37.5% traditional concentration gel). Color changes were measured objectively using total variation in color (ΔE), and subjectively using Vita Classical and Vita Bleached scale (ΔSGU) by calibrated evaluators (Kappa=0.85). The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) and Oral Health Impact Profile (OHIP-14) aesthetic questionnaires were used to measure the self-perception and the psychosocial impact of the bleaching protocols. Results: The effect (ΔE) of 37.5% HP (8.37 ± 2.73) was significantly better than that of 6% HP (5.27 ± 2.53) in terms of color rebound after one year of follow-up. There were significant differences in psychosocial impact and esthetic self-perception measurements prior to bleaching versus one-year post-whitening time points; positive effects were maintained. Conclusions: Low concentration (6%) achieved effective bleaching with good stability after one year, accompanied by a positive psychosocial impact and enhanced self-perception at follow-up. Trial registration: NCT03217994 (before enrollment of the first participant). Data register: July 14, 2017

The aim of this study was to compare the change and stability of color with low-concentration (6%) hydrogen peroxide gel in an in-office bleaching setting relative to conventional 37.5% gel including their effects on psychosocial and esthetic self-perception at one year. Methods: Patients (n=25) were assessed at 12 months post bleaching treatment ( whitening with 6% activated chemo gel of alkaline formula v/s traditional concentration 37.5% ). Color changes were measured objectively using total variation in color (ΔE) and subjectively using Vita Classical and Vita Bleached scale (ΔSGU) by calibrated evaluators (Kappa=0.85). The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) and Oral Health Impact Profile (OHIP-14) aesthetic questionnaires were administered to measure self-perception and the psychosocial impact of the whitening procedure. Results: The effect (ΔE) of 37.5% HP (8.37 ± 2.73) was significantly better than that of 6% HP (5.27 ± 2.53) in terms of color rebound at one year of follow-up. There were significant differences in psychosocial impact and esthetic self-perception measurements prior to bleching versus the one-year post-whitening time points; positive effects were maintained. Conclusions: Low concentration (6%) achieved effective bleaching with good stability at one year. This was accompanied by a positive psychosocial impact and enhanced self-perception at follow-up.

Internalizing And Externalizing

The coping power universal (CPU) is an evidence-based universal prevention program delivered by teachers, and completely integrated into the school agenda. Previous studies have shown its positive effects, though little is known about its longer-term effects, and no previous study has explored whether teachers’ occupational stress could influence the CPU efficacy. The current study aimed to explore the 1 year follow up of the CPU on students’ externalizing and internalizing problems and prosocial behavior, and the influence of baseline levels of teachers’ stress in a sample of 316 3rd graders and their teachers (N = 32). Results showed that the CPU led to positive effects, not attainable with the standard curriculum. Additionally, improvements in prosocial behavior persisted even one year after the conclusion of the program. However, improvements in internalizing and externalizing problems were not maintained at the follow up, highlighting the need to understand the factors influencing the CPU efficacy. In this regard, our findings showed that high levels of teachers’ occupational stress predicted poorer improvements following the CPU, and an increase in students’ difficulties at the follow-up assessment. Addressing teachers’ stress as part of prevention programs for students could boost their efficacy and yield more lasting results.

Objectives: In this study, we prospectively assessed changes in smoking a year after US adults' first-time purchase of a JUUL Starter Kit (JSK). Methods: Descriptive analyses assessed transitions in smoking status at 12 months among adult (age ≥21) JSK purchasers providing baseline and 12-month follow-up data (N = 27,164 [49.0% of baseline]), stratified by baseline smoking status. Baseline regular use of other ENDS was also considered. Results: Purchasers included baseline past 30-day smokers (65.2%), former smokers (12.0%), and never smokers (9.7%); over 90% were ever-smokers. One year later, the majority (58%) of those smoking at baseline reported no longer smoking. Former smokers or never smokers who were smoking at 12 months represented less than 2% of respondents. Former and current smokers who were regularly using other ENDS at baseline were less likely to report smoking at 12 months. Conclusions: Past 30-day smoking prevalence in a large longitudinal study of first-time JSK purchasers fell by more than half over 12 months. Analyzing the sample composition at purchase and transitions within subgroups defined by smoking status allows for a detailed understanding to help inform assessments of the population health impact of ENDS.

Objective — to investigate the dynamics of levodopa-therapy in patients with Parkinson's disease (PD) after unilateral stereotactic radiofrequency pallidotomy (USRP). Materials and methods. From 2008 to 2016 USRP was performed in 16 patients (7 men and 9 women from 48 to 73 years old, average — 56 years) with PD complicated by levodopa-induced dyskinesias and motor fluctuations (MF). The dynamics of the disease symptoms was interpreted on the basis of separate sections and points of the UPDRS. The levodopa-equivalent dose (LED) was calculated using standard conventers. Patients were evaluated before, one week and then one year after surgery. Results. One week after the USRP 43.2 % reduction of average daily LED was noted. The decrease of severity of MF and motor symptoms of the OFF-period on the contralateral side was traced. After 1 year of follow up the rate of reduction decline of the average daily LED compared to its preoperative level was 22.3 %. The recurrence of the MF and the steady positive effects on the motor symptoms of the OFF-period on the contralateral side were observed. Conclusions. Primary reduction of the daily LED effects of USRP decrease during one year of observation in the background of the MF recurrence, despite the steady positive effects on the motor symptoms of the OFF-period on the contralateral side.

Aim: To develop a simple approach to estimate quality-adjusted tooth years of teeth (QATY) treated for periodontitis and determine gains in QATY after undergoing cause-related periodontal therapy (CRPT). Quality-adjusted life years (QALY) gained for these patients were also determined. Materials and Methods: Patients newly diagnosed with periodontitis ( n = 165, 58.8% females, mean age 43.3 years) were recruited from periodontal specialist clinics. They received CRPT within a period of one year. We used the EuroQoL 5 Dimension (EQ-5D) and the Malaysian Oral Health Impact Profile (OHIP-14) indexes to measure changes in quality-of-life after one year of periodontal treatment. We then used these two scores to calculate their respective utilities and subsequently calculated QALY and QATY. Results: Proportions of deep periodontal sites (≥ 4 mm) decreased from 32.7% to 23.2% and patients gained an average of 0.3 mm of clinical attachment level per tooth at post-treatment follow-up. Improvements in means of OHIP-14 scores from 20.30 to 12.7 were consistent with changes in EQ-5D utilities from 0.81 to 0.91. Treated teeth gained 20.4 years for longevity while patients gained 17 QATYs. This is in line with the increase of 3.8 QALYs. Both treatment outcomes and clinical parameters were statistically significant at P < .0001. Conclusions: The method of estimating QATY using utilities derived from OHIP-14 combined with tooth life expectancy demonstrated that it may be used to measure effective treatment outcomes and is found to be consistent with improvements in QALY scores as calculated using EQ-5D-3L.

Abstract Objective To investigate the effects of low-concentration hydrogen peroxide pretreatment on the anti-oxidative stress of the bone marrow mesenchymal stem cells (BMSCs). Methods Rabbit BMSCs were isolated and cultured by density gradient centrifugation combined with the adherence method. Then, the third generation of well-grown BMSCs was continuously treated with 50-μM hydrogen peroxide (H2O2) for 8 h as the optimal pretreatment concentration and the BMSCs were continuously applied for 24 h with 500 μM H2O2, and the optimal damage concentration was determined as the oxidative stress cell model. The experiment was divided into three groups: control group, high-concentration H2O2 injury group (500 μM), and low-concentration H2O2 pretreatment group (50 μM + 500 μM). In each group, the DCFH-DA fluorescence probe was used to detect the reactive oxygen species (ROS). ELISA was used to detect the activity of superoxide dismutase (SOD) and catalase (CAT), and the TBA method was used to detect malondialdehyde (MDA). The mitochondrial membrane potential was detected by JC-1. The cell viability was detected by CCK-8 method, while flow cytometry and TUNEL/DAPI double staining were performed to detect cell apoptosis. Hence, the effect of H2O2 pretreatment on the anti-oxidative stress of BMSCs was investigated. One-way analysis of variance was performed using SPSS 19.0 statistical software, and P < 0.05 was considered statistically significant. Results A large number of typical BMSCs were obtained by density gradient centrifugation and adherent culture. The oxidative stress cell model was successfully established by 500-μM H2O2. Compared with the high-concentration H2O2 injury group, the low-concentration H2O2 pretreatment reduced the production of ROS [(62.33 ± 5.05), P < 0.05], SOD and CAT activities significantly increased (P < 0.05), and MDA levels significantly decreased (P < 0.05). The mitochondrial membrane potential fluorescence changes, the ratio of red/green fluorescence intensity of the high-concentration H2O2 injury group was less, and the ratio of the low-concentration H2O2 pretreatment group was significantly higher than that. The ratio of red/green increased by about 1.8 times (P < 0.05). The cell viability and survival rate of BMSCs were significantly increased in low-concentration H2O2 pretreatment group (P < 0.05), and the cell apoptosis rate was significantly decreased (P < 0.05). Conclusion Pretreatment with low-concentration H2O2 can enhance the anti-oxidative stress ability and reduce their apoptosis of BMSCs under oxidative stress.
