Purpose: We present a new Colombian product researched and developed by Seven Scientific Foundation, which has been very useful for the removal of the carious tissue in patients who have used this innovative product.Methods: We used a chemical-mechanical removal of dental caries. This product is made with 10% papain which is the active principle and works as a debriding agent, as well as being a bacteriostatic, bactericidal and anti-inflammatory agent; and also contain dragon’s blood (Croton lechleri) sap which is an effective as analgesic/anti-inflammatory and especially as a healing agent. In this article, we present a case study of a patient, whose dental carious tissue was removed, using the dental new product. Description of the case report: in this article, we present a case study of a patient, whose dental carious tissue has been removed, using the new dental product, therefore this innovative technique of removal of the atraumatic carious tissue. Conclusions: This method is useful as it is a minimally invasive technique, without requiring the use of local anesthesia, or the additional use of dental instruments. It is used in the Colombian population of all ages and does not generate side effects in people who have used it so far.

<div class="section abstract"><div class="htmlview paragraph">Vehicle OEM’s for MHD applications are facing significant challenges in meeting the stringent 2027 low-NOx and GHG emissions regulations. To meet such challenges, advanced engine and aftertreatment technologies along with powertrain electrification are being applied to achieve robust solutions. FEV has previously conducted model-based assessments to show the potential of 48V engine and aftertreatment technologies to simultaneously meet GHG and low NOx emission standards. This study focuses on evaluating the full potential of 48V electrification technology through addition of 48V P3 hybrid system to the previously developed 48V advanced engine and aftertreatment technology package.</div><div class="htmlview paragraph">Previously, a model-based approach was utilized for selection and sizing of a 48V system-enabled engine and aftertreatment package for class 6-7 MHD application. The advanced engine and aftertreatment technology package comprised of engine downspeeding, exhaust VVT, close-coupled SCR, and 48V system components such as ETurbo , EGR pump, and catalyst heater. The performance of the advanced engine and aftertreatment package was compared to that of the baseline engine over engine certification cycles.</div><div class="htmlview paragraph">To assess the full potential of the 48V technology, the advanced engine and aftertreatment package was integrated with a 48V P1P3 hybrid powertrain. The performance of the baseline and the advanced vehicle were compared over the 3 Bin Moving Averaged Method instituted by CARB under omnibus regulation. The critical parameters compared were fuel economy, tailpipe NOx emissions, aftertreatment system temperature, and payback period. The analysis showed the potential offered by the 48V hybrid system for meeting future low NOx and GHG emission regulations.</div></div>
