You have never felt a composite like this!

Alert® (Amalgam-Like Esthetic Restorative Treatment) from Pentron® Clinical Technologies is a revolutionary condensable* composite, developed as an esthetic alternative to amalgam and traditional hybrid composites.


Several features distinguish Alert® from traditional composites:
  • Ease of insertion: Alert® is highly condensable*, allowing the practitioner to bulk fill up to 5mm without pull-back or the creation of voids. Tight anatomical contacts are easily obtainable.
  • High wear resistance: Alert® has shown** to be significantly more wear resistant than either hybrid, highly filled microfill or other condensable composites.
  • Lower shrinkage: Alert® has a polymerization shrinkage of less than 2% by volume***.
  • Improved physical properties: Alert® has a higher modulus of elasticity than hybrid composites, reducing stress on the margins of the restoration.
  • Alert® is radiopaque and available in five popular shades (A2, A3, A3.5, B1, C2). Alert® is now even more convenient to use as it is available in syringes, unidoses and in a new compule format.

Professionals Agree:

“The resin matrix of Alert Condensable Composite consists of two different systems. These include both polycarbonate dimethacrylate (PCDMA) and ethoxylated Bis-GMA. The microfillamentous hard glass fillers are in turn coated with colloidal silica. The combination of these various systems results in a highly packable (condensable) composite resin, truly appropriate for posterior teeth.”

Dr. Karl Leinfelder, D.D.S., M.S.

What makes Alert® different?

As with all composites, Alert® is a combination of glass fillers blended into a resin matrix. What makes Alert® revolutionary is the introduction of a unique elongated chopped glass fiber filler particle. This particle is coated with silane and silicate nanofiller and introduced into the resin matrix along with traditional fillers.

*Some of you may not approve of the word “condensable” since in fact no matter is truly condensable. However, this word best describes the tactile sense when placing the composite. Technically, amalgam is not condensed, the mercury is brought to the surface of the alloy/mercury mix).


Alert® features:

  • Highly condensable, feels like amalgam
  • Very low shrinkage (under 2%)
  • No tackiness or pull back
  • High strength properties
  • Easily forms contacts with conventional amalgam techniques
  • Easy to form anatomy and contour
  • Radiopaque.
