What causes oral leukoplakia?


The exact cause of oral leukoplakia is still unknown, although certain risk factors have been identified. More
than 80% of patients with oral leukoplakia have a history of tobacco use and the condition is six times more
common among smokers than non-smokers. Other risk factors include excessive alcohol use (especially in
people who also smoke), a weakened immune system, long-term treatment with immune suppressing
medications, a history of cancer, a family history of cancer, and in some cultures, the chewing of areca nut and
betel leaf.

What is oral leukoplakia?



Oral leukoplakia (leuko=white, plakia=patch) is a white patch in the mouth that cannot be scraped off and
cannot be diagnosed specifically as something else. It appears white usually because of three main factors
alone or in combination: hyperkeratosis or excessive production of keratin (the white flakes that come off
when you scratch your skin), thickening of the surface layer of cells, or the presence of pre-cancer
(“dysplasia”) or cancer. Lichen planus, yeast infections (“thrush”) and chronic cheek and tongue chewing
injuries are some of the specific conditions that appear white in the mouth and are therefore not oral
leukoplakia. When all such known conditions have been ruled out, a patient is diagnosed with oral
leukoplakia.
Oral leukoplakia occurs in 1-2% of the population and is most common in patients over age 40. The more
common kind of oral leukoplakia is limited to one location in the mouth and is more common in men. It may
affect any part of the mouth, but is usually on the tongue, gums and inner cheeks. Research has shown that
oral leukoplakias on the underside of the tongue, floor of mouth and soft palate are more likely to become
precancerous/dysplastic. Some oral leukoplakias are not just white but may appear red, rough and warty or
bumpy. These too, have a higher chance of being precancerous/dysplastic.

DENTAL THERAPY MANUAL


Clinical Application:
CHEESE 810nm diode laser for dental therapy from GIGAALASER
Clinic Explanation:
Laser analgesia
Enamel etching: remove the tarter or to prevent the calcify of tooth
Related Keywords:
Laser hemostasis, laser analgesia, enamel etching, laser remove tarter.
Medical device:
CHEESE4w/ 7w 810nm 1-5w
Accessories:
Dental surgery handpiece, 400um fiber
a.       Connect dental surgery handpiece with device, and setting the parameters.
b.      Wearing a laser safety goggles, starting laser and irradiation on the target part.  
1.      Hemostasis: 1.5w-3w; pulse 20/20
            1w-1.5w CW
Non-contact, at a distance of 1-2cm with back and forth sweep till the tissues was grey or dark brown.
Non-contact, at a distance of 1-2cm with spiral sweep till the tissues was grey. Usually, 15-30 seconds is ok.
Use dental handpiece whisk and sweep the surface of enamel to make the etching effects with non-contact way.
Advantage:
810nm diode laser system brings about a striking effect in a very short time for dental therapy.
Notice:
Do not contact the tissues directly with fiber, keep distance and control the time experienced

PERIODONTAL POCKETS TREATMENT MANUAL


Clinical Application:
CHEESE 980nm diode laser for dental from GIGAALASER
Clinic Explanation:
Periodontal Pockets are dental terms indicating the presence of an abnormal gingival sulcus near the point at which the gums contact a tooth.

Related Keywords:
Gingical pockets, periodontal pockets
Medical device:
CHEESE7w 980nm; 2-4w; continuous wave
Accessories:
400um fiber, dental surgery handpiece
1.      Connect dental surgery handpiece with device, and setting the parameters.
2.      Wearing a laser safety goggles, starting laser and aiming the fiber toward the tissue.
3.      The light guide was introduced into the periodontal pocket and moved from apical to coronal, parallel along the root surface, in a sweeping way.

Advantage:
The diode laser reveals a bactericidal effect and helps to reduce inflammation in the periodontal pockets in addition to scaling.
Notice:
The duration of lasing depended on the depth of the respective periodontal pocket. For example, 3-mm-deep pockets are irradiated for 3 seconds, 4-mm-deep pockets for 4 seconds

Cheese 7W for Periodontal treatment

Periodontal diseases are an inflammatory condition caused by the presence of bacteria. Periodontal therapy is to incision the granulation and suppressing or eliminating the bacteria.

Operation procedure:
1. To calibrate the fiber and the tip, measure the length of fiber so it equals the pocket depth, minus 1 mm
2. Initiate the fiber at 400um by touching the tip to articulating paper and test firing.
3. To begin sulcular debridement, insert the fiber in a vertical direction toward the bottom of the pocket with the laser tip oriented toward the soft tissue facing the pocket
4. Move the fiber in a horizontal and vertical fashion at a slow, moderate speed, keeping the fiber tip in contact with the epithelium and/or parallel to the root surface.
5. Debride all granulation tissue, and as necessary, remove plume and debris with high-volume evacuation.

Cheese Series Dental Diode Laser for Abscess Drain


Abscess drainage is a procedure to incision the abscess and drain the pus in it.

1.      Local anesthetic
2.      Connecting dental surgery handpiece with device, setting the parameters.
3.      Wearing a laser safety goggle, starting laser and directing at the most swollen area of the abscess, incision the abscess.
4.      Once the abscess is incised, the pus will drain out and it is left open to continue draining by itself. By removing the pus which consists of bacteria, the tooth and gum tissue will start healing by itself.

Veterinary Lasers

GIGAA supplies CHEESE™ ,VELAS™ and GBOX™ serials medical diode lasers from 2.5W to 60W with wavelength of 810nm or 980nm, which have been used in many human clinical applications in the world.The practice and education of GIGAA Diode Laser also have been the driving force promoting the growth of laser use in veterinary medicine. During the past few years, however diode lasers have virtually replaces Nd:yag lasers or CO2 lasers for fiber directed laser surgery because of their smaller size, increased versatility and decreased maintenance requirements. At the highest setting, you will find that the GIGAA Diode Laser is as easy to use as a scalpel for everyday procedures. The accuracy of the laser beam targets and vaporizes the pigmented cellular structures in soft tissue. At low wattage, you can use the GIGAA Diode Laser for therapeutic procedures to promote healing as well as control pain, inflammation, and infection.
