In this study were treated 40 patients with OVM with a range size from 2 mm to 44 mm; they were subjected to clinical examination supported by Colour-Doppler Ultrasound instrumental examination and only for doubt cases the Magnetic Resonance Imaging MRI was prescribed.
These techniques permitted a good control of haemostasis, avoiding bleeding both during surgery and in the postoperative. A clear diagnosis allowed the management of Venous malformations VM by laser devices with wavelengths highly absorbed in haemoglobin in safety and efficacy and according to globe dating site principles of minimal invasive surgery.
The aim of this study was to verify if the laser is effective in the treatment of OVM for the purpose of the clinical findings and the postoperative course.
The Authors concluded that the laser can be considered the "gold standard" for treating OVM. Author s : Roeland J. De Moor ; Maarten A. Meire; Rudolf M. Verdaasdonk Show Abstract The major problem of irrigation is the fluid motion within the confined geometry of the root canal : efficient dispersion of the liquid is difficult, conventional irrigation is limited due to the absence of turbulence over much of the canal volume, vapour lock may limit apical cleaning and disinfection, there is also a stagnation plane beyond the needle tip.
The best way to improve irrigant penetration and biofilm removal is achieved by means of the agitation of the fluid. Today ultrasonic activation appears to be the best way to activate and potentiate irrigants among the present-day used means and marketed systems. Another way to activate irrigation solutions is the use of lasers: laser activated irrigation or photon-initiated acoustic streaming have been investigated.

Based on present-day research it appears that the efficacy of laser activation especially with Erbium lasers can be more efficient thanks to the induction of specific cavitation phenomena and acoustic streaming. Other wavelengths are now explored to be used for laser activated irrigation. Symptoms are epistaxis, visceral arterio-venous malformations, multiple muco-cutaneous telangiectasia with the risk of number increasing enlargement, bleeding, and super-infection. EL preventive treatment consists of single Laser cwu dating de viteză fibre in ultrapulsed mode 2 mm single point spot.
According to the results, Diode Laser used in pulsed and ultra-pulsed mode is very effective as noninvasive treatment both in early and advanced oral and perioral telangiectasia.
LM may grow slowly over years or develop rapidly over the course of days becoming a bulky lump, infected or bleeding. We propose our three steps Diode Laser protocol for LM management, based on its persistent vascular blood component.
Use of Diode Laser also in surgical excision reduces intra and postoperatory complications. Author s : Luminita Nica ; Carmen Todea ; Gabriel Furtos; Bogdan Baldea Show Abstract Bonding to root canal dentin may be difficult due to various factors: online dating mid 20s structural characteristic of the root canal dentin, which is different from that of the coronal dentin; the presence of the organic tissue of the dental pulp inside the root canal, which has to be removed during the cleaning-shaping of the root canal system; the smear-layer resulted after mechanical instrumentation, which may interfere with the adhesion of the filling materials; the type of the irrigants used in the cleaning protocol; the type of the sealer and core material used in the obturation of the endodontic space; the type of the materials used for the restoration of the endodontically treated teeth.

Recently, a new and innovative biotechnology was developed — Icon, a caries infiltrant to be introduced in early tooth lesions, able to achieve a very good preservation of dental structures.
In order to assess the infiltrant penetration level inside the white spot lesions, a non-destructive 3D visualization method is needed. Phase-contrast micro computed tomography using synchrotron radiation proved to be a powerful technique, allowing a 3D morphological investigation of all the components of interest: tooth structure, white spot lesions extension, infiltrant penetration inside the lesions, without the need of slicing the specimens.
From our clinical experience and the conducted research we can conclude that this technology is effective and useful in many clinical situations encountered in pediatric dentistry.
Imperceptible cell dysfunction that is not corrected early can lead to disease. Fine-tuning can be done daily in only minutes, using pulsed electromagnetic fields PEMFs. In addition, when there is a known imbalance when symptoms are present or there is a known disease or condition, PEMF treatments, used either alone or along with other therapies, can often help cells rebalance dysfunction faster.

Most treatment protocols include strong antibiotics, disregarding their side effects and interactions with other medications. Results: The patients reported no pain, bleeding, swelling or major discomfort during the postoperative control of the following day.
In terms of psycho-emotional reactions, both patients well behave well, the calm being given by no pain, bleeding, suture or edema. Discussions: The accuracy of this method, as well as the use of additional means of healing, allow satisfactory results both for patient and physician.
Conclusions: Our study reveals that the possibilities regarding the surgical modeling of the lower lip frenulum are higher due to laser than the classical surgical approach.
Moreover, a major role in the prevention of relapse by inappropriate healing is represented by the approach of frenectomy accompanied by frenuloplasty. A controlled clinical study was conducted in a group of 93 patients presenting various forms of oral soft tissues benign tumors. These patients were examined pre-and postoperatively and the oral benign tumors were measured linearly and photographed.
The surgery of laser-assisted biopsy excision of oral benign tumors was carried out using a diode laser device of nm. In patients who received surgical laser treatment, therapeutic doses of laser to biostimulate the operated area were administered on the first day after the surgery.
The interventions of conventional excision of charlie brooker internet dating soft tissues benign tumors consisted in removing them using scalpel.
In patients who have received therapeutic doses of laser for biostimulation of the operated area, a faster healing of wound surfaces and tumor bed was observed during the first days after surgery. Two weeks after the surgical treatment, good healing without scarring or discomfort in the area of excision was documented. Surgical treatment of oral soft tissues benign tumors with laser assisted postoperative therapy confirms the benefits of this surgical procedure.
