Herpes Zoster and Nd:YAG Photobiostimulation

Herpes Zoster is a viral disease that affects the skin and the ganglia in the spinal nerves. The disease causes damage to the myelin nerve fiber, which is characterized by the emergence of intensely painful macro papules and vesicles borne by the skin dermatome concerned. Laser photobiomodulation is now a treatment option for this disease. Low-power laser therapy activates the lymphatic and blood microcirculation, increases the level of endorphins with painkiller and anti-inflammatory effects and accelerates the regeneration of nerve and skin tissues.
It is contraindicated in patients with pacemakers, epileptic patients and pregnant women.

Skin Resurfacing with Er:YAG – the Lost Art of…

The process of aging affects all human organs, including the skin. In addition to the effects of chronological aging, human skin is also exposed to the outside environment. Ultraviolet (UV) radiation is of particular importance in so-called photo-induced skin damage. This can present as deep wrinkles, roughness, sallowness, hyperpigmentation, laxity and telangiectasia. Different treatment options are available for the treatment of skin affected by chronological and photo-induced aging, with chemical peels, dermabrasion and laser resurfacing being three of the most commonly used procedures. There seem to be several advantages of laser treatment over chemical peels and dermabrasion, with one of the most useful being the ability to control ablation depth. The most commonly used lasers for facial resurfacing are Er:YAG and CO2 lasers, which both work by vaporizing the damaged layer of surface skin.
This paper reports on a case of treatment of a severely damaged skin utilizing a 2940 nm Er:YAG laser (Dualis SP, Fotona). Impressive visual results can be achieved using a combination of planar (full spot) and fractional ablative Er:YAG short pulses.

New Treatment Protocol for Periodontal Pocket Treatment using a…

Periodontitis is the most common chronic inflammatory disease in European adults. Eight out of ten individuals over 35 suffer from some kind of gum complaint. It is associated with systemic diseases, including type 2 diabetes, cardiovascular disease and stroke. Although common, periodontal diseases are not very well acknowledged.
To date, mechanical therapy has been the general treatment for plaque-induced periodontal disease, however, many studies have shown that mechanical treatment itself does not lead to a complete healing because it does not eliminate the periopathogenes.
Laser therapy may constitute an efficient alternative to surgical treatment. Based on the research, data and experience of many practitioners, we can enumerate the potential advantages of laser therapy, such as bactericidal, detoxification and homeostatic effects and biostimulation. Laser treatment facilitates the eradication of bacteria and better wound healing.
It is also easy to use, provides good access to anatomically difficult areas and offers a comfortable treatment for patients.
High-energy lasers are applied in periodontal procedures as an adjunctive therapy or as an alternative to conventional procedures, and have become the standard treatment of periodontal pockets. Their effectiveness in eliminating periodontal pathogens and decreasing pocket depth is widely documented. The Neodymium:Yttrium–AluminumGarnet (Nd:YAG) laser with a wavelength of 1,064 nm can decontaminate periodontal pockets without causing necrosis or carbonization of the underlying connective tissue. [6] Periodontopathogens can persist within cells outside the pocket epithelium after conventional mechanical periodontal debridement, and Gianelli et al. reported that the Nd:YAG is capable of eradicating periodontopathogenic bacteria trapped within gingival epithelial cells.
Erbium:YAG (Er:YAG) laser, with a wavelength of 2,940 nm, has been applied for effective elimination of granulation tissue, gingival melanin pigmentation and gingival discoloration. This laser is also used for contouring and cutting of bone with minimal damage and enhanced healing [8]. In addition, irradiation with the Er:YAG laser has a bactericidal effect with a reduction of lipopolysaccharides, it is efficient in calculus removal, with the effect limited to a very thin layer of the surface, and it is effective for implant maintenance.

Socially Disabling Warts

Warts are small viral cutaneous neoplasms which can affect any area of skin. Clinically, they are classified as verruca vulgaris (common wart), verruca plana (flat wart) and verruca plantaris (affecting the sole of the foot).
In this case report a Caucasian male aged 69 with a painless exophytic cutaneous neoplasm on the perioral region of the upper lip was treated with 2940 nm Er:YAG laser. 8 days after the treatment there were no signs of inflammation and at the 30-day follow-up, the skin was fully healed. Removal of common warts with the Er:YAG, proved to be effective in controlling and preventing the recurrence of viral infection.
The treatment can be carried out as outpatient procedure and is not associated with any early or late complications. It provides a quick, safe and comfortable treatment for patients.

Treatment of warts with 1064 nm Nd:YAG

wart-pngCutaneous warts are benign epidermal proliferations caused by human papillomavirus infection. Among the available medical and destructive therapeutic options for cutaneous warts, none is uniformly effective or virucidal. Laser light was previously shown to be effective in treatment of warts. Many studies have used 585-nm pulsed dye lasers with the wart blood vessels as the target tissue. Nd:YAG 1064 nm laser was also previously shown to be effective for wart clearance. In our case report, four cases of wart removal with 1064 nm Nd:YAG are presented. In all cases a successful treatment of the warts was achieved. There were no reoccurrence of warts. Pain during a treatment was diagnosed as moderate and transient in nature. Apart from the transient pain there were no other unwanted side effects reported. We can conclude that wart removal with 1064 nm Nd:YAG is a safe, effective and well-tolerated treatment with no adverse events reported.

Specific Oral Bone Surgery Procedures Requiring the Use of…

BoneThis case report presents modern alternatives to classical oral-surgery procedures with the use of Erbium lasers, which allow a shorter recovery period, no recurrence and no need for antibiotic protection. A minimally invasive approach provides more predictable results in different age groups of patients, minimizing the importance of the general condition of the patient on the success of the operation. Methods for bone augmentation and bone sculpture, with a corresponding dosage of laser energy are shown, regulating the residual low energy as needed for indirect stimulation (or non-stimulation) of the neighboring tissues. For example, upon removal of the exostoses, it is not desirable to use too high power due to saturation of the target and the influence on the underlying tissues, with the consequent risk of stimulation of new exostoses. And opposite to this – on procedures for bone augmentation, additional stimulation is desired with a view to obtaining a larger volume of bone tissue. QSP mode allows the operator to have a fine-tuned dosage according to the specific goals of each procedure

Er:YAG Laser Resurfacing Treatment of Linear Verrucous Epidermal Nevus

VLENThe subject case of this report is a 22-year-old female patient with Verrucous Linear Epidermal Nevus (VLEN) who underwent Er:YAG laser resurfacing. The lesion unilaterally affected the external side of the upper left arm from the cubital space to shoulder, the left mammary region, the left neck region, and the left part of the back from the shoulder to the gluteal region. Several dermatological treatments were previously performed without significant results. Prior to laser treatment, skin biopsies were taken and histopathology examinations showed hyperkeratosis, papillomatosis and acanthosis with elongation of the rete ridges, with no pigmentary incontinence or dermal abnormalities. We performed resurfacing with a 2940 nm Er:YAG laser with percutaneous local anesthesia. After lasing in the cold ablation regime, the vaporized, atypical, disorganized epidermal cells were replaced with normal, well-organized keratinocytes from the follicular adnexa. The Er:YAG resurfacing technique provided complete removal of the lesion in two treatments, which was very important considering the large surface treated.
This case clearly shows the benefit of Er:YAG laser ablation as a highly precise, simple, and effective method for treating VLEN.

Use of Er:YAG and Nd:YAG Lasers During Orthodontic Treatment

vestibular frenectomyIn recent years laser technology has played an increasingly important role in modern dentistry and, recently, the utilization of laser devices has also been proposed in orthodontics.
The aim of this work is to describe the use of combined laser devices (Fidelis and LightWalker AT, Fotona, Slovenia: 1064 nm and 2940 nm) in soft and hard oral tissues to improve orthodontic treatment. Several cases treated by Er:YAG and Nd:YAG in different stages of the treatment (before, during and after) are presented. All the cases showed, as reported in the literature, that the use of lasers with orthodontic treatment offers several advantages when compared to conventional methods.
In soft-tissue surgery, it allows practitioners to reduce or eliminate the use of anesthetic injection, to avoid the use of sutures and to bond brackets in dry enamel. Combined with orthophosphoric acid, it provides a stronger adhesion of the brackets to the enamel and helps to prevent carious lesions around the brackets. It may even be used to repair broken appliances by welding them intra-orally.

Combined Er:YAG and Nd:YAG Laser Treatment for Non-invasive Body…

tighteningAlthough laser lipolysis has been described as a “lunchtime treatment”, it is nevertheless classified as a surgical procedure associated with certain risks due to surgical incisions and the use of anesthetics, as well as with subsequently reduced skin firmness and lack of skin ability to conform to the reduced body size.
We aimed to develop a safe and effective alternative to address both excess body fat as well as surface appearance of the skin on the selected body areas.
The method is based on the application of a combination of 2940 nm Er:YAG thermal pulse for controlled surface tissue heating with subsequent collagen remodeling and 1064 nm Nd:YAG super-long pulse for deep bulk heating of the skin with the purpose of both reducing adiposity and shaping the body by heating shrinkable connective structures.
This method, which was later developed into the TightSculpting™ procedure, has proven to be a non-invasive, safe and comfortable body-sculpting solution with long-lasting effects.
