Treatment of Periodontal Pockets with A Diode Laser

The aim of this study is to examine the long-term effect of diode laser therapy on periodontal pockets with regard to its bactericidal abilities and the improvement of periodontal condition.

STUDY DESIGN/MATERIALS AND METHODS

Fifty patients were randomly subdivided into two groups (laser-group and control-group) and microbiologic samples were collected. There have been six appointments for 6 months following an exact treatment scheme. After evaluating periodontal indices (bleeding on probing, Quigley-Hein) including pocket depths and instruction of patients in oral hygiene and scaling
therapy of all patients, the deepest pockets of each quadrant of the laser-group’s patients were
microbiologically examined. Afterwards, all teeth were treated with the diode laser. The control-group received the same treatment but instead of laser therapy were rinsed with H2O2. Each appointment also included a hygienic check-up. After 6 months the final values of the periodontal indices and further microbiologic samples were measured. The total bacterial count as well as specific bacteria, such as Actinobacillus actinomycetemcomitans, Prevotella
intermedia, and Porphyromonas gingivalis, were assessed semiquantitatively. 

RESULTS 
The bacterial reduction with diode laser therapy was significantly better than in the control group. The index of bleeding on probing improved in 96.9% in the laser-group, whereas only 66.7% in the control group. Pocket depths could be more reduced in the laser group than in the control group. 

CONCLUSION
The diode laser reveals a bactericidal effect and helps to reduce inflammation in the periodontal pockets in addition to scaling. The diode laser therapy, in combination with
scaling, supports healing of the periodontal pockets through eliminating bacteria.

The Diode Laser as an Electrosurgery Replacement

Advantages of Diode Lasers Over Electrosurgery

The term “electrosurgery” is not as well known or as accepted by many patients as the term “lasers.” Having said this, the acceptance of this technology in both medicine and dentistry, as a viable method of soft-tissue alteration has made electrosurgery an accepted alternative to the scalpel.


The diode laser has become a popular technology as an alternative for tissue management compared to the traditional methodology of placing a single or double retraction cord in the
sulcus. Many CEREC users routinely use the diode laser to enhance the gingival trough when the margin is either equi-gingival or subgingival, prior to powdering their prep for their digital
impression. The diode laser can be used in almost all instances to produce gingival retraction as an alternative to cord with excellent results both in terms of gingival retraction and margin delineation for the laboratory. Diodes, like electrosurgical units, offer the clinician the ability to work in a bloodless field for the impressions because of the hemostasis that occurs during the procedure. Unlike electrosurgical units where recession can be an issue, as can postoperative pain, diode lasers offer the clinician the ability to precisely remove overhanging, inflamed tissue while creating a gingival trough that is not likely to cause damage to bone, cementum, or pulp tissue like electrosurgical units can.

Conclusion:

Diode laser wavelength is 810nm, there is a better role in the solidification and gasification. Meanwhile, the deoxy-hemoglobin absorption of 810nm wavelength laser, the highest rate, so the diode laser has a good hemostatic effect. Diode laser temperature curve steep, that is, the penetration depth of laser light, the surrounding deep tissue safer.Studies have confirmed that endovenous laser treatment in the peak temperature oftreatment area will not cause permanent heat damage outside the organization. Take advantage of this feature to avoid surgery anal sphincter damage the thermal coagulation.

Accordingly, through the fiber hemorrhoids in diode laser irradiation, selectively makehemorrhoids venous plexus and the surrounding tissue coagulation degeneration, fibrosis,vascular occlusion to make hemorrhoids, hemorrhoids shrinking fixed, the purpose ofcorrecting prolapsed hemorrhoids.

Diode laser coagulation hemorrhoids and hemorrhoidectomy is different in the treatment of hemorrhoids when you only to insert thin laser fiber, the use of the laser characteristics make hemorrhoidal venous plexus and surrounding tissue coagulation variability, withoutany incision and excision method is simple and , trauma, postoperative pain and thereforea minor. In addition, the removal of anal cushions for failing organization, they can be used to maximize the protection of anal function. The technology is also different from sclerotherapy, as sclerotherapy, and not directly to the expansion of the hemorrhoidal venous plexus degeneration of occlusion, it may be easy to relapse after treatmenthardening agent one of the reasons.

Cervix–Cervical Intraepithelial Neoplasia (VAPORIZATION)

Cervix–Cervical Intraepithelial Neoplasia

Although treatment of cervical intraepithelial neoplasia (CIN) is now more commonly performed by the large-loop excisional technique, the laser was the ideal method of treatment of the 1980s and still offers another option. Treatment of CIN can be performed by vaporization or by excisional conization using the laser as a substitute for the scalpel. The major advantages of the laser for the treatment of CIN include:

1. High degree of clinical efficacy
2. Bloodless field
3. Microscopic precision
4. Sparing of normal tissue
5. Rapid healing with minimal scar formation
6. Small number of complications
7. Outpatient methodology

VAPORIZATION

When using the laser coupled to the colposcope, one should first define the extent of the lesion. One should keep in mind that endocervical glands may lie deep in the stroma to a depth of 6–7 mm; therefore, treatment should be carried out to a minimum of 9–10 mm with a peripheral margin of 3 mm. This procedure is performed with 30–40 W of power with a 2-mm-diameter spot and takes about 5–10 minutes to complete under local anesthesia. Vaporization is performed to a minimal depth of 1 cm and ends at the level of the endocervical canal. The cervical defect should resemble a funnel, as if one performed a small cone biopsy.

The operative site is circumferentially outlined with a 3- to 5-mm margin around the lesion. The cervix is then divided into four quadrants. Power is increased to 30–40 W. Beginning in the lower quadrants and using a circular pattern, vaporization is carried down to a depth of 1 cm. The endocervical canal is usually spared. Measurements are made at frequent intervals, relating the depth to the surrounding ectocervical surface. When the lower half of the cervix has been vaporized, a similar procedure is followed for the anterior surface.

Medical device:Velas 30W 980nm with CW

Accessories:600um optical fiber;1 mm cannula;18 gauge needle;lipolysis handpiece

Operation procedure:Treatment parameter:Power: 18WOperation mode: CW

1. Obtain the patient's consent to take photographs, use a marking pen o draw a topographic map of the areas to be aspirated while the patient is standing, entry points are identified and marked, and the skin is disinfected.

2. Use ultrasound imaging to determine the volume of the fat layer, control tumescent anesthesia infiltration, cannula position prior to laser emission, and postoperative fat liquefaction.

3. Place patient on steriledrapes and/or towels under local anesthesia with adrenaline 1:500 000.

4. Inject tumescent fluid and create a small stab incision of 1-2 mm, just enough to accommodate the infiltration needle.

5. The patient and staff should wear safety goggle.

6. One hand is used to introduce cannula into the deep fat layer and move, creating a radial pattern. Cross-hatching, or inserting the cannula from two different axes (usually perpendicularly), creates a smoother result, the other hand contact with the treated area.

7. Drop out cannula, put lipolysis handpiece with 600um fiber and turn the output power at 18W to burning.

8. Connected to the aspirator (or sometimes a syringe), place the liposuction cannula through the insertion site. Liposuction removes significant amounts of fat, serum and blood.

9. Access wounds are closed with one to two buried absorbable sutures, and place sterile dressings.

10. Compression garments and absorptive pads are applied to the wounds immediately postoperatively and may be worn for up to 1 month or more, there were no restrictions to activity, except sun exposure, depending on the surgeon.

Advantage:

 1. There is a greater potential for skin tightening without the increased risk of severe superficial thermal damage.

2. Stimulates collagen formation, enhancing skin elasticity and promoting skin contraction.

3. Laser lipolysis is more suitable for treating small and compact areas. Furthermore, it can also be used to improve local irregularities after conventional liposuction.

Notice:

1. If the main objective of laser lipolysis is fat liquefaction, reduced bleeding and tissue tightening are also important.

Biological Effects of Laser

● Thermal effect: the irradiated tissue can elevate temperature, correct optical output port temperature is even a few hundred or thousands of degrees, use the organization to make the water boiling, increase pressure, and separate organization. At the same time, make the edge to have a coagulation or vaporization, so you can get a cutting, freezing, evaporation and other clinical results.

● Photochemical effect: biological macromolecules absorb the laser photon energy and cause chemical reactions in vivo series, it can reduced the activity of enzymes, amino acids, proteins, nucleic acids, or have an effect on treatment and diagnosis.

● EMF effect: in the form of electromagnetic fields play a role in biological tissue.

● Pressure effect: radiation pressure, air recoil pressure, pressure within the gasification, thermally induced expansion of pressure, electrostrictive pressure and so on.

● Stimulating effect: mainly in the weak laser, biology absorb photons, get energy, change and have biological reaction.

Weight Loss

Loving beauty is the nature of female. And now it is also the nature of male and children.

However, obesity, also called fat person is an increasingly serious problem in western countries and the quantity has dramatically increased since 1995. According to WHO (World Health Organization) report, the fat person who’s BMI index over 30 has increased from 200million in 1995 year to more than 300million in 2000 year. To make things worse, more and more young people and even the children become fat. The obesity not only causes a series diseases but also brings psychological problems. Most people are unconfident or feel inferior for their overweight body shape. So, loss weight is a problem of great urgency.

There are many methods to lose weight, such as, on diet, take exercise and weight loss drug etc. However, on diet and take weight loss drug is unhealthy, it always associate with a series side effect. We usually learnt from newspaper that someone is fall in a faint or malnourished for on a diet, or even death by eat weight lose drug. Take exercise is a health method, but it is a long process, most people are failed because they can’t insist it. Besides, take exercise is not effect to resistant fat.

To solve the increasingly serious obesity problem, we need to find a quickly, safety and effective method. Liposuction comes at his proper moment. Liposuction is a cosmetic surgical procedure which removes unwanted areas of subcutaneous fat. Thanks to mini-invasive surgery, less pain and bleeding, it is now widely used, particularly in America and Europe. According to a survey, the USA government cost more than 900 billion on treatment of obesity and it relevant disease. As big market demand, the liposuction market has become the one of the hottest business.

Laser Liposuction Vs. Traditional Liposuction

Function
Both traditional and laser liposuction procedures have the same function: to rid the fat deposits that affect the aesthetic of the body contour and cause the cellulite "dimples" in the skin. The traditional method is focus on rid larger amount of dis-proportioned fat, like fat in thigh. While the laser liposuction provides ideal fat melt performance for every position, even in neck or chine. What’s more, the laser lipolysis is base on thermal effect, it can tighten the skin during the procedure.

Invasive Vs. Non-Invasive
Traditional liposuction is an invasive surgical procedure, meaning that incisions are made into the skin so that the surgeons can work below the surface skin layers. Laser liposuction is a non-invasive or minimally invasive procedure, depending on the amount of fat.

Technique
Traditional liposuction involves the removal of fat through the suction of a straw-like tube (canulla). Laser guided liposuction employs high-energy thermal laser beams that penetrate the skin tissue and heat the fat deposits in the skin's lower layers, breaking up and emulsifying these deposits, and also stimulating new collagen and elastin growth in the skin.

2 Clinic Science:

Although the real pathophysiology of hemorrhoidal disease remains controversial, the‘‘vascular’’ theory has recently been considered a very likely potential cause of hemorrhoids.

According to this theory, arterial overflow in the superior hemorrhoidal arteries would lead todilatation of the hemorrhoidal venous plexus based on the anatomical findings of arteriovenoushemorrhoidal shunting system without capillary interposition.

Due to preferential thermal coagulating effect on blood of 980nm wavelength, the shrinkageeffect of the laser on submucosal arteries is more selective and periarterial damage of themucosa is extremely reduced.

3 Clinic Procedure:

1) No anesthesia.

2) A specially designed disposable proctoscope is inserted into the rectum3) At the distal end of the proctoscope, there is a small window that holds a Doppler transducer.

3) The Doppler probe identify the terminal branches of the superior hemorrhoidal arteries approximately 3 cm proximal to the dentate line.

4) Once the arterial flow is located, remove the Doppler probe and replace the 600um fiber.

5) Release the laser and reintroduce the Doppler probe to check the closure of the artery.

Advantage:

No anesthesia

Reduced risk of complications

Quick recovery for laser treatmentUsually provide immediate relief of symptoms
