“Evaluation of Irradiance and Composite Depth of Cure with a Laser Curing Light over Distance: An In Vitro Study”

Omer Sanabria, Joseph L. Gedge, Terrell M. Mitchell, James J. Renda, Kraig S. Vandewalle

Summary:

Study tested the irradiance and depth of cure of two resin-based composites (RBCs) using Monet and single- and multi-spectrum LED curing lights over various distances. 

Key Findings:

• From 0 to 10mm, Monet produced a slight increase in irradiance, while the LED curing lights showed significant decreases. 
• Significant differences in depth of cure were observed depending on RBC and curing light type, exposure length, and distance. 
• Monet produced a greater depth of cure with a three-second exposure than the LED curing lights produced with ten-second exposures on both RBC types across all distances.

“Effect of Beam Divergence on the Irradiance from Dental Light Curing Units” 

Anubhav Gulati, Soheil Ghaffari, Brett Daniel MacNeil, Richard Bengt Price 

Summary:

Study evaluated light output and beam divergence angle for twenty curing lights using wide beam imaging to determine relationships between beam divergence, irradiance, and distance from the light tip. 

Key Findings:

• From 0 to 10mm, Monet experienced the smallest decrease in irradiance and least beam divergence of all lights tested. 
• Monet delivered 10 J/cm2 of energy fastest of all lights tested across all distances. It also experienced almost no change in delivery time. 
• There is a positive correlation between beam divergence angle and irradiance reduction.

“In Vitro Pulpal Temperature Increases when Photo-Curing Bulk-Fill Resin-Based Composites Using Laser or Light-Emitting Diode Light Curing Units” 

Cristiane Maucoski, Richard Bengt Price, Braden Sullivan, Juliana Anany Gonzales Guarneri, Bruno Gusso, Cesar Augusto Galvão Arrais 

Summary:

Study measured the in vitro pulpal temperature increase inside the pulp chamber during the photo-curing of low- and high-viscosity bulk-fill RBCs with various curing lights. 

Key Findings:

• Monet produced the lowest temperature increase of all lights tested for Class I and Class V cavities when exposed for one second. 
• During three-second exposures, Monet produced mean temperature increases in the lowest 50% (Class I) and 25% (Class V) of all lights tested. 
• Different composite types did not produce significant differences in temperature increase for equivalent exposures.

“Depth of Cure of 10 Resin-Based Composites Light-Activated Using a Laser Diode, Multi-Peak, and Single-Peak Light-Emitting Diode Curing Lights” 

Mateus Garcia Rocha, Cristiane Maucoski, Jean-François Roulet, Richard Bengt Price 

Summary:

Study evaluated the depth of cure of ten RBCs photo-cured by various curing lights for various exposure times. 

Key Findings:

• With three-second exposures, Monet produced cures of at least 2mm in all RBCs tested and a maximum depth of 4.91mm. 
• With one-second exposures, Monet produced cures of at least 2mm in all but two RBCs tested and a maximum depth of 4.29mm. 
• One- and three-second exposure results for Monet are generally comparable to 10- and 20-second exposures from LED curing lights. 

In addition to its ongoing involvement in research studies around the world, Monet has been tested by trusted independent clinical evaluation facilities.

“Laboratory Evaluation of Monet Laser Curing Light” 

Matt Cowen, B.S., John M. Powers, Ph.D.

Summary:

Evaluators photo-cured three RBCs with Monet and two LED curing lights to determine depth of cure. Radiant power was also measured. 

Key Findings:

• Three-second Monet exposures produced comparable cures to 20-second exposures with the tested LED curing lights. 
• Monet produced no significant difference in depth of cure at 2mm and 10mm distance.

“Curing Lights: Laser Diode Versus Other Light Sources” 

Gordon J. Christensen

Summary:

Evaluators made general performance comparisons with LED, plasma arc, and halogen curing lights. 

Key Findings:

• Monet produced the highest irradiance and fastest cure speed of the tested lights.  
• It also produced the narrowest spectral emission, compatible with all RBCs tested.
