The beam dimension is fixed at 2 mm. The oral mucosal site selected for melanin pigmentation is the buccal attached gingiva on the left and right side of maxillary arch. On each side of the arch, the experiment site was divided into two groups,. E., an anterior group related to incisor-premolar region and a posterior group related to molar region. On the left maxillary arch, two buccal sites were selected, one for micro-short pulse (MSP) group (anterior) and second for the long pulse (LP) group (posterior) (Fig. On the right maxillary arch, two similar buccal sites were selected, one for short pulse (SP) group (posterior) and second for very long pulse (VLP) group (anterior) (Fig. 2 ).Therefore, a total of four groups for laser depigmentation testing parameters were created, and each group received six different power settings (fluences) sites, namely.3, 2, 3, 4, 5, and 6 J/cm2.Each mucosal pigmented site selected was 2 mm2 in size.

Materials and methods, this study is done in two phases, firstly in a laboratory experiment on ex-vivo pigmented oral gingival tissue using the sheeps oral cavity, and the best parameters are then selected and tested in a clinical trial on human volunteers. The study was approved by comentarios research and Ethics Committee in health Campus in University Science malaysia. Phase i—ex-vivo animal study on sheeps oral mucosal pigmentation. One adult sheeps complete head and oral cavity was taken from registered abattoir for experiment. The head was immediately stored in the freezer at. The time between death and beginning of laboratory experiment is less than 4 h to prevent undesirable post-mortem biological changes. The sheeps oral cavity was examined to ensure that it was normal and free of any mucosal pathology. All the teeth were present and intact and attached and free gingiva was healthy. There was no obvious dental pathology. The sheeps mucosa was examined and identified for sites of melanin pigmentation. Selection of power settings, power settings selected was based on the lowest setting available in the laser machine and increasing the power gradually up to 6 J/cm2, below the ablation threshold of enamel, which is about 10 J/m2 when pulse duration is 150 μs, and 7 J/cm2 when pulse.

Het gaat hierbij om kleine hoeveelheden. Maar bij de tweede bereiding ging het al veel beter.

Super-pulsed mode of CO2 laser was first mentioned by Esen. When they applied 10 watts with pulse duration of 10 ms to ten patients with oral gingival hyperpigmentation. They reported again that this laser parameter setting was effective for oral gingival depigmentation. There are no studies comparing the different power settings within the same laser system when performing depigmentation procedures. Such procedure needs accurate handling of the laser handpiece by the operator with stable controllability, minimal carbonization of the operation site that allows good vision and a fairly painless and comfortable experience for the patient. Laser ablation results phlebotomist in elimination of pigments from the basal layer of epithelium, resulting in a raw desquamated surface that often bleed but leaving the deeper lamina propria and mucoperiosteum intact. Underlying bone and neighbouring roots of teeth are thus protected from harmful thermal changes. An optimum power setting for Er:yag may deliver more effective ablation effects, resulting in complete removal of the melanin pigments and a pleasing esthetic outcome without recurrence. The aim of this study is to determine the range of favorable power settings of laser depigmentation on oral mucosal melanin pigment; using the laser System Er:yag laser (Fotona, fidelis Plus iii d based on clinical and biological parameters.

This clinical finding is in agreement with the study of kaya et al where they as well did not apply topical or local anesthesia intraoperative when using Er:yag laser to treat hyperpigmentation. En tant que bourgeon, il est également un haut lieu d'activité biologique puisque zone de forte croissance. Specimens were placed in formalin solution 10 and send to the lab at the University Science malaysia for processing, stained with h e staining for microscopic analysis. Five joule per square centimeter may be acceptable but considering the larger amount of water content in human tissues, so we decided to decrease the highest power setting to 4 J/cm2 fluence.

high water absorption, thin surface interaction, and producing less tissue degradation. However, no optimum laser power setting parameters has been recommended for its use in gingival and oral mucosal depigmentation procedure. Up to the end of 2016, there were less than 50 studies in the literature describing the work on Oral Mucosal Laser Depigmentation, found in PubMed search. Very few studies discussed on power settings for optimum results in laser oral depigmentation procedure. Conducted two prospective studies in oral depigmentation using Er:yag laser. The first study applied 850 mJ with a peak power.13 W on five patients. The second study employed 500 mJ applied to ten patients but without mentioning the peak power employed. They found similar conclusions at the end of both studies and added that Er:yag laser seems to be the laser of choice for depigmentation 7,.

Gingivoplasty techniques have also been employed to remove pigmented gingiva. Re-pigmentation occurred in 67 of the areas, as early as 33 days after surgical removal.

Yag laser Pigmentation Treatment, this video is about yag laser treatment of skin pigment spots (lentigines). The laser is a safe and lamellen effective way to remove surface pigment spots, which will dry up and flake off within 5 - 7 days after the treatment. Introduction, melanin, a natural brown pigment produced by melanocytes is found in the basal layer of the epithelium. Although melanin found on gingiva may denote a racial trait, an abundant amount on the anterior gingiva causes gingival hyperpigmentation and poses an esthetic problem to the individual. Many physical, chemical, and surgical methods have been advocated as standard dental procedures to remove gingival hyperpigmentation, particularly from the anterior labial gingival part of the oral cavity, with varying clinical outcomes. Historically, 90 phenol and 95 alcohol has been used to remove areas of oral pigmentation. Although this chemical technique is effective in removing oral mucosal pigmentation, recurrence was the main problem.
