5.3 TISSUE RESPONSES TO LASER ENERGY
Maximum results will be achieved by regulating the power and the speed that the operator moves the fiber tip.
Tissue Charring is an undesirable after effect of too much power or the tip moving too slowly. Always use the
least amount of power necessary to complete your procedure. The ideal tissue response will show little or no
discoloration after lasing and there will be less residual damage and faster healing. Avoid penetrating or damaging
the periosteum, and do not use the laser on alveolar bone. Because the laser energy is attracted to melanin and
hemoglobin, power must be reduced when treating patients with darker soft tissue. Always begin lasing with the
lowest power you can use to remove or modify the target tissues. Avoid damage to the gingival sulcus by moving
the fiber tip quickly and using low power settings. Check so that no shard is present on the tip. A shard may act as a
miniature scalpel and damage the small blood vessels, thus preventing hemostasis and coagulation.
5.4 SYSTEMS PROCEDURES
5.4.1 Treatment Area Requirements
The laser should be placed in an area with good ventilation and lighting. The electrical service required is a
110 - 240 Volt AC outlet 50 - 60 Hz. The area where the laser is placed should be free of standing water.
Combustible gases or those that support combustion should be turned off and all flammable materials or chemicals
stored in the area should be removed.
5.4.2 Foot Pedal
It is recommended to use a 9 volt Lithium battery to power the cordless foot pedal. This type of battery has been
tested to last for over 100 hours of foot pedal operation. When the battery voltage begins to drop, the foot pedal
will begin to beep, signaling that you have approximately 2 hours of operating time left before the battery life is
completed.
NOTE: A 9 volt Alkaline battery may be used, however the life expectancy of an Alkaline battery is less than 35 hours
of operating time.
5.4.3 Unit-Dose Fiber Tip
Make sure the tip is “snapped” onto the handpiece. Please read chapter 6.3.4 for test instructions.
5.4.4 Fiber Preparation/Initiation
To prepare the fiber for cutting, if your procedure calls for it, set the power to 1 watt, activate the laser, and touch
the tip to black or blue articulating paper. This initiates the tip for cutting.
5.4.5 Emergency Shut Off Button
Check the Emergency Shutdown Button to see that it is depressed, if not, gently depress the button.
5.4.6 Digital Key
Activate the digital key by entering 1234 on the touch pad. The Main Menu screen will appear.
5.4.7 Setting Parameters for the Quick Set Mode
Review your power and mode requirements and then depress the mode button to select either Continuous (CW)
or pulsed mode.
