30 days wild: development and evaluation of a large-scale nature engagement campaign to improve well-being

There is a need to increase people’s engagement with and connection to nature, both for human well-being and the conservation of nature itself. In order to suggest ways for people to engage with nature and create a wider social context to normalise nature engagement, The Wildlife Trusts developed a mass engagement campaign, 30 Days Wild. The campaign asked people to engage with nature every day for a month. 12,400 people signed up for 30 Days Wild via an online sign-up with an estimated 18,500 taking part overall, resulting in an estimated 300,000 engagements with nature by participants. Samples of those taking part were found to have sustained increases in happiness, health, connection to nature and pro-nature behaviours. With the improvement in health being predicted by the improvement in happiness, this relationship was mediated by the change in connection to nature

Changes in Caries Risk in a Practice-Based Randomized Controlled Trial

To demonstrate that Caries Management by Risk Assessment (CAMBRA) can be successfully implemented in dental practice, 30 dentists were recruited to perform a 2-y CAMBRA trial. Twenty-one dentists (18 private practices, 3 community clinics) participated in a randomized, controlled, parallel-arm, double-blind clinical trial with individual-level assignment of 460 participants to standard of care (control) versus active CAMBRA treatment (intervention). Control or active antimicrobial and remineralizing agents were dispensed at baseline and 6-, 12-, 18-, and 24-mo recall visits according to risk level and assigned treatment arm. Primary outcome measure was dentist-determined caries risk level at recall. Among initially high-risk participants, secondary outcomes were recorded disease indicators. Generalized estimating equations were used to fit log-linear models for each outcome while accounting for repeated measurements. At 24 mo, follow-up rates were 34.3% for high-risk participants (32.1% intervention, 37.1% control) and 44.2% for low-risk participants (38.7% intervention, 49.5% control). Among 242 participants classified as high caries risk at baseline (137 intervention, 105 control), a lower percentage of participants remained at high risk in the intervention group (statistically significant at all time points). At 24 mo, 25% in the intervention group and 54% in the control group remained at high risk ( P = 0.003). Among 192 participants initially classified as low risk (93 intervention, 99 control), most participants remained at low risk. At 24 mo, 89% in the intervention group and 71% in the control group were low caries risk ( P = 0.18). The percentage of initially high-risk participants with recorded disease indicators decreased over time in both intervention and control groups, being always lower for the intervention group (statistically significant at the 12- and 18-mo time point). In this practice-based clinical trial, a significantly greater percentage of high-caries-risk participants were classified at a lower risk level after CAMBRA preventive therapies were provided. Most participants initially assessed at low caries risk stayed at low risk (ClinicalTrials.gov NCT01176396)

Comparative clinical evaluation of the immediate and late analgesic effect of GaAlAs diode Lasers of 830 nm and 660 nm in treatment of dentine pain - Preliminary results

In this comparative clinical study, we aimed at evaluating the immediate and late analgesic effect of GaAlAs diode lasers of 660 nm and 830 nm in treatment of dentine pain.We used GaAlAs diode lasers of 660 nm and 830 nm with 35 mW, continuous wave emission, spot size 1 mm(2) and a dosage of 4 joules/cm(2) applied to the cervical dentine surface. in total 4 treatment sessions were performed at intervals of 7 days in a period of 4 consecutive weeks.A total of 40 teeth treated were divided into two groups comprising 20 teeth each: one group irradiated with a 660 run wavelength laser, and the other one with a 830 nm wavelength laser.By means of a quantitative visual analogue scale (V.A.S.), we measured the sensitive responses to cold stimulus pretreatment, and at a follow-up period of 15 and 30 minutes post-treatment in both groups in order to evaluate the immediate analgesic effect. the late effect was evaluated at a follow-up period of 15 and 30 days.Using the GaAlAs diode laser of 660 nm wavelength resulted in better levels of dentine desensitization, at both inmediate and late analgesic effect analysis compared with the use of the GaAlAs diode laser of 830 run wavelength.Universidade Federal de São Paulo, EPM, São Paulo, BrazilUniversidade Federal de São Paulo, EPM, São Paulo, BrazilWeb of Scienc

Comparative clinical study of the effect of LLLT in the immediate and late treatments of hypoesthesia due to surgical procedures

We evaluated the effect of LLLT in 68 patients who presented hypoegthesia due to odontological surgery procedures: dental implant surgeries (N=51); extraction of impacted lower third molars (N=10); endodontics in lower first molars (N=7).Lesions treated within 30 days after the nerve injury had occurred were part of the immediate group, and lesions with more than 30 days from the occurrence of the injury were part of the late group. mm(2),Treatments were carried out with an infrared diode laser of 40 mW - 830nm, continuous wave emission, spot size 3 and a total dosage of 18 joules per session in a contact mode application, 20 sessions altogether.The efficacy of laser therapy in peripheral nerve regeneration is also related to the degree of the peripheral nerve lesion, and not only to the lesion duration.LLLT resulted in neurosensory functional improvement in both immediate and late treatments of hypoesthesia.Universidade Federal de São Paulo, EPM, São Paulo, BrazilUniversidade Federal de São Paulo, EPM, São Paulo, BrazilWeb of Scienc
