General Guidelines Ensure that treatment is not contraindicated (see manual) and that eye protection is worn. Treat directly in the mouth, observing cross infection precautions - removable tips are autoclavable. Specialist dental tips are available for best access. Application Guidelines 660nm: Treat directly onto the gum line at points no closer than 1cm apart across the affected teeth. Probe Time per Point Dose per Point Pulse Range 660nm 50mW 1 minute 24 J/cm2 1-5 kHz Frequency of Treatment Ideally twice, but at least once per week. N.B. There is also evidence of effectiveness in the use of near infra-red light to affect nociceptor (rather than red-light to affect dentine) but the red-light treatment had better outcomes on direct comparison.
