The class iv studies are still few and sometimes surprisingly biased.
Class 3 vs class 4 laser therapy.
Knowing the difference and how each will affect the type of treatment you can provide is important when deciding on a laser therapy system.
There is zero published evidence to show that a class 4 laser penetrates deeper than a high powered 3b laser.
This is not an obsolete printout it is a state of the art app that runs on a phone tablet or computer.
If the class iv laser is in the 940 980nm wavelength range then it.
It will be listed either in arabic numerals 1 2 3r 3b 4 or in roman numerals i ii iiia iiib iv.
3b lasers are safer.
Basics of laser classification.
Many people that don t get results with a class 3b and below will get results with a class 4.
Assessment of feasibility and efficacy of class iv laser therapy for postoperative pain relief in off pump coronary artery bypass surgery patients.
But the standard class 3b laser turned out to be a very weak laser pointer.

3b laser systems cost less.
Class 4 cold lasers may be the ultimate therapy laser for many applications but that really depends more on the requirements of the practice.
One of the major differences between laser therapy systems is whether they are a class iii 3 or class iv 4 laser device.
Others offer pulsing to allow for heat dissipation.
Most laser products are required by law to have a label listing the class.
Thus a class 3b laser can penetrate deeper into tissue than a class iv laser and can therefore saturate the target faster.
The pressure will also lead the laser probe closer to the target.
The industries best protocol library every laser comes with the laser therapy us protocol library and training tool.
This app follows the best practices for laser therapy and dynamically creates pictorial treatment plans for over 250 different conditions for humans pets and horses.
One paper 5 claims that class iv laser produced better healing of oral mucositis than a standard class 3b laser.
The bottom line is that class 4 system deliver results.
The k cube 4 is a high powered class iv therapy device with power adjustable from 100 milliwatts to 15 000 milliwatts 15 watts allowing for a wide range of treatment protocols.
The effectiveness of therapeutic class iv 10w laser treatment for epicondylitis.
This power and penetration of the k laser system is not attainable with cold laser class iii devices.
Class iv laser companies use class 3b evidence to promote their products because they don t have much of their own.
As an example a class 4 laser emitting 880 and 970 nm laser light at 10 w average power with a beam surface area of 10 cm producing a radiant exposure of 1000 mw cm thus exceeding the safe exposure limits known as the maximum permissible exposure limits mpe which range from 200 mw to 500 mw cm depending on wavelength.
