Abstract: A cladding panel that collects and/or emits thermal energy, which includes: a first panel; a second panel with an extrados adhered to an intrados of the first panel, forming a leaktight seal, with a low-relief channel, the channel being attached to the intrados of the first panel to form a conduit; an inlet connector for heat-conducting fluid, connected to a first end of the channel; and an outlet connector for heat-conducting fluid, connected to a second end of the channel, wherein the first panel is made of calibrated laminated ceramic with a flat, smooth intrados and a flat, smooth extrados and has a uniform thickness of 3-6 mm, and the second panel is made of waterproof heat-insulating plastic that is stable up to 120° C.

Abstract: A composition comprising nanoparticles, a method for the preparation of a composition comprising nanoparticles and uses of the composition for dental treatment are provided. Each nanoparticle is made of polymeric material and includes an antimicrobial agent encapsulated therein. The polymeric material can include Poly(lactic-co-glycolic acid) (PLGA), or other polymers such as Polylactic (PLA), Polyglycolic (PGA), or Polycaprolactone (PCL). The active molecule is calcium hydroxide in the range of 0.1 to 5 mg/ml. The composition has a pH in the range of 8-13.
