“…Dengue is the main vector-borne disease affecting tropical and subtropical countries worldwide, including Malaysia [ 1 , 2 ]. Globally, dengue incidences have increased to 100 million cases, with up to 500,000 cases of haemorrhagic dengue recorded each year [ 3 , 4 ].…”

“…The thermal spray technique interferes with the viral transmission cycle by killing its main vector within 24 h. This technique should be initiated immediately the first case is reported. The fogging disinfectant is sprayed on indoor and outdoor premises that are potential breeding sites of the Aedes mosquitoe [ 2 ]. ULV foggers convert the fogging liquid to a fine mist which is dispersed into the air at high velocity.…”

Fogging to combat dengue: factors influencing stakeholders' attitudes in Malaysia

Background Fogging is a conventional technique used to combat Aedes mosquitoes and prevent dengue disease. It is often implemented in outbreak areas or areas harbouring a high density of Aedes mosquitoes. Currently, studies on stakeholders' attitudes towards fogging are still limited in number. Therefore, this study aims to assess Malaysian attitudes, and identify the predicting factors influencing such attitudes. Methods A validated instrument was used to interview 399 randomly selected respondents from the public (n = 202, 50.6%) and scientists (n = 197, 49.4%) in the Klang Valley region of Malaysia. The data were analysed using PLS-SEM involving Smart-PLS software. Results The results confirmed that stakeholder attitudes toward fogging should be viewed in terms of a multi-dimensional association. The stakeholders surveyed were highly positive with regard to the application of fogging to control dengue but professed moderate concerns as to associated risks. The PLS-SEM analyses demonstrated that the perceived benefit was the most important factor influencing attitudes, followed by trust in key players. Conclusions This result provides a good insight from the perspective of education and unravels the underlying fundamentals of stakeholders' attitudes toward the fogging technique. The findings also provide a positive indicator to the responsible parties involved to continue the usage of this technique in conjunction with improvements with regard to its safety aspects, and possibly in combination with other environmental-friendly alternatives in order to achieve a healthy environment without dengue in Malaysia.

“…Dentistry industry has long sought to develop high-strength and long-lasting connections between restorative materials and tooth structures 1 . Adhesive systems are used to increase composite resin attachment to the dental structure, and they should behave similarly on both dentin and enamel 2 . Dental bonding to enamel is regarded as long-lasting and steady clinical technique 3, 4. Attempts to bind to dentin in the same way as enamel have been investigated 4 .…”

“…Dental bonding to enamel is regarded as long-lasting and steady clinical technique 3, 4. Attempts to bind to dentin in the same way as enamel have been investigated 4 . The dentin substrate is different from enamel, as it contains more organic materials, more fluid in its tubules, the smear layer, and intrinsic moisture 2,5 .…”

To study the relevance of dentin moisture state on the micro-tensile bond strength (µTBS) and bonded interface morphology when using two universal adhesives with different compositions. Materials and Methods: Sixty-third molars randomly allocated into 12 groups based on adhesive types (Prime & Bond Universal [P&BU], Dentsply Sirona, New York, USA and Single Bond Universal [SBU], 3M ESPE, Neuss, Germany), adhesives application approach (etch and rinse or self-etch), and the amount of moisture found on surface of dentin (dry, wet & visible moist dentin surface). Thirty-six molars were divided into beams of composite and dentin with adhesive interface for µTBS (n=20) after restoration. Twenty-four molars were used to create specimens for scanning electron microscope evaluation of the bonded interface (n=2). For statistical analysis, three-way ANOVA was used, followed by a multiple comparison with Bonferroni adjustment. Results: In etch and rinse, P&BU had higher µTBS than SBU when the dentin surface was dry, SBU had higher µTBS when the dentin surface was wet. There were no differences between both adhesives on the moist dentin surface. In selfetch, SBU had higher µTBS than P&BU on the moist dentin surface, there were no significant differences between the two adhesives on dry and on wet dentin surfaces. For both adhesives, SEM images revealed better hybrid layer morphology and integrity with a greater number of resin tags and deeper penetration in etch and rinse approach than self-etch. Moist dentin surface developed better interface morphology than dry dentin surface, but wet dentin surface had the poorest hybrid layer quality with scarce resin tags in both adhesives. Conclusion: When dentin was moist or dry, universal adhesive systems demonstrated good adhesive performance. The response in wet dentin, on the other hand, is material composition dependent. Universal adhesives are better utilized in etch and rinse approach than the self-etch approach.

“…For decades, vector control has remained the principal intervention against Aedes mosquitoes as a safe and efficacious dengue vaccine is not yet available. Recent vector control tools developed to reduce dengue burden include insecticide-, biological-, gene-, and mechanical-based tools (Lee et al, 2015).…”
