Whitening toothpaste containing activated charcoal, blue covarine, hydrogen peroxide or microbeads: which one is the most effective?
Conclusion: Only WAD and 3DW showed whitening performance after the first use (TI). The greatest whitening performance after continuous use was obtained by WAD, followed by LWA and 3DW. The use of conventional toothpaste (TA) promotes no tooth whitening. Clinical relevance: Microbead abrasives (3DW) and blue covarine (WAD) were the active technology tested that presented the best global tooth whitening performance.

Assessment of anesthetic properties and pain during needleless jet injection anesthesia: a randomized clinical trial
Conclusions: The two anesthetics methods did not differ concerning the pain experienced during anesthesia. Latency lasted 2 minutes for all subjects; the traditional infiltration anesthesia resulted in a longer anesthetic duration compared with the needleless jet injection.

BK virus salivary shedding and viremia in renal transplant recipients
Conclusion: The results of this study suggested that, although saliva excretes more BKPyV than blood, there is no reliable correlation between salivary shedding and blood viremia, showing two independent compartments of viral replication. (Source: Journal of Applied Oral Science)

Distribution of depression, somatization and pain-related impairment in patients with chronic temporomandibular disorders
Conclusion patients with TMD frequently present an emotional profile with low disability, high intensity pain-related impairment, and high to moderate levels of somatization and depression. Therefore, given the importance of psychosocial issues at the prognostic level, it is recommended that clinical trials on TMD treatment include an evaluation of patients ’ psychosocial profiles.

Influence of surfactants addition on the properties of calcium hypochlorite solutions
Conclusion Surfactant addition to 2.5% Ca(OCl)2 has shown acceptable outcomes for pH, free chlorine content, surface tension, contact angle, pulp dis solution and antimicrobial activity. Furthermore, the addition of 0.2% Cet showed better results for all tested properties. (Source: Journal of Applied Oral Science)

Shrinkage stress and elastic modulus assessment of bulk-fill composites
Conclusions: Bulk-fill resin composites presented equal to lower shrinkage stress generation when compared to conventional composites, especially when bigger increments were evaluated. Bulk-fill composites showed a wide range of elastic modulus values, but usually similar to “ regular ” composites. (Source: Journal of Applied Oral Science)

Effect of radiant exposure and UV accelerated aging on physico-chemical and mechanical properties of composite resins
Conclusions: Although increasing radiant exposure affected the degree of conversion and mechanical properties of micro-hybrid and nanofilled composites, no influence on the hydrolytic degradation of the material was observed. In contrast, UV accelerated aging affected both the physico-chemical and mechanical properties of the composites. (Source: Journal of Applied Oral Science)

Efficacy of sonic and ultrasonic irrigation devices in the removal of debris from canal irregularities in artificial root canals
Conclusions No significant differences were found between 5% sodium hypochlorite and 17% EDTA. When the time of activation rises, the dentin debris removal increases in all groups. Both sonic and ultrasonic activation demonstrate high capacity for dentin debris removal. (Source: Journal of Applied Oral Science)
