Soft tissue Laser (Diode) in Dentistry
Types of lasers: Diode (soft tissues), co2, Erbium laser (hard
Diode laser, the difference between average and exceptional
results in Dentistry. It needs only 5-10 minutes working time,
no or little post operative pain, monochromatic, 810
nanometers wavelength while the curing length between
430– 380 nanometers.
Functions of the Diode laser: It uses light to produce
thermal energy. Light is absorbed by the melanin and
hemoglobin in the soft tissues which produces heat that is
responsible for the cutting and coagulation effects.
Advantages of soft tissue lasers (Diode Laser): improve the
esthetics, reduce the chair time, increase the success rate,
decrease the healing time (no sutures needed), decrease the
shrinkage of tissues, infiltration anesthesia only, less bleeding
and there is No need for retraction cord packing.
The uses of Diode lasers in: frenectomies, operculectomies,
gingival recontouring, removal of growths and lesions
(fibroma, apthus ulcers, biopsies) and in periodontal
pocketing to kill the bacteria inside (New technique).
Effects of lasers on the soft tissues: vaporization of the cells
coagulation protein denaturation carbonization
(blackening of the tissues with excess water and heat)
Ablation, incision, sealed and sterilized wound area.
