9:00 - 9:55 Use of laser in the management of oral soft tissues and in oral esthetics
Prof. Samir Namour

The use of CO2 laser beam in oral surgery has several advantages: bloodless surgery, good aspect of healing (no scar formation), no need for suturing, immediate decontamination of the surgical site, good visibility of the surgical field, fast work, positive psychological impact on patients,… The use of CO2 laser in oral surgery is helpful. The no need for suturing avoids the anatomical deformation of the surgical site and the decrease of the vestibular lengthening of the crest. The bloodless surgery and the low inflammatory reaction decrease the post- surgical discomforts and patient complaints. Several clinical cases (general oral surgeries, Prosthetic Fibroma, Floated ridge, vestibular lengthening, crown lengthening, removal of gingival pigmentation (Melanin) , removal of gingival Amalgam tattoo, Esthetic correction of lips’ design,  …) will be showed and discussed. The clinical procedure: step by step, the limits and the advantages of the laser use will be exposed. Surgeries were done using laser output power ranges from 2 to 10 W in a continuous or super-pulsed and focus mode. The small size of beam diameter allows the dissection of oral tissues with high precision. The complete and good quality of Healing took place with minimal post-operative, discomfort and pain complaints. The use of CO2 laser in oral surgery gave better results than those of conventional treatment.

9:55 - 10:50 Laser – Assisted Bleaching and the Introduction of Er,Cr:YSGG for the first time!
Prof. Dimitrios Strakas

Since the introduction of lasers to the field of teeth bleaching, the process has been reported to be safer and more efficient. Only recently did the erbium family of lasers start utilizing for this purpose. A review of the literature so far will be presented. This lecture will also reveal the extensive research that we have done, regarding the introduction of Er,Cr:YSGG for laser-assisted teeth bleaching. Different protocols will be presented and answer the questions on safety and efficiency of the procedure. A variety of materials and methods have been used and this will be highlighted with background analysis, statistical data and photographic documentation. The goal is to introduce a new wavelength of 2780 nm to the field of dentistry to perform laser-assisted teeth whitening.

13:15 - 14:15 Can we use the laser for treating the true leukoplakia?
Prof. Umberto Romeo

Oral leukoplakia has been redefined as a predominantly white lesion of the oral mucosa that cannot be characterized as any other definable lesion. Definitive treatment of oral leukoplakia is very important because of its recurrence and its potentiality to the malignant transformation. Clinicians treated oral leukoplakia with two modalities: non surgical (Vit. A, Vit. E and beta-carotene) and surgical. The surgical treatment modalities for oral leukoplakia are scalpel excision or electrocautery and cryosurgery, for which there is a recurrence rate of approximately 33%.Studies on the clinical usefulness of laser surgery in oral leukoplakia have shown that the laser surgery prevents not only recurrence and malignant transformation, but also postoperative dysfunction. The Author through the scientificliterature and the presentations of some clinical cases, wants to show ifand when is indicated the use of laser for treating oral leukoplakia.

Podczas wykładu przedstawione zostaną wskazania do wykonania poszczególnych procedur regeneracyjnych oraz dane dotyczących ich skuteczności w zależności od zastosowanych biomateriałów, technik chirurgicznych i urządzeń, w tym laseroterapii.

17:30 - 18:20 Treatment of periimplantitis with using Er:YAG laser in combination with Photodynamic therapy
Prof. Adriana Barylak

  The presence of bacteria on the implant surface may lead to inflammation of the mucous membrane around the implant. If this inflammation is not treated, it will spread in the apical direction, which will lead to resorption of bone tissue and possible loss of the implant. For the treatment of periimplants, it is important to remove bacterial plaque and inflammatory tissues, to protect the surface of the implant. Er: YAG laser is able to remove infected soft and hard tissue around the surfaces of implants. Since this wavelength is poorly absorbed by the titanium surface of the implant, the temperature around the implant during irradiation does not significantly increase, therefore, does not lead to pyrolytic effects. The purpose of this clinical trial was to evaluate the effectiveness of the use of Er: YAG laser in the treatment of peri-implants in combination with photodynamic therapy. Materials and methods: Under supervision were 25 patients with 42 implants. All our patients have been diagnosed with peri-implants. The patients were divided into two groups. First group: 10 patients (15 implants) were treated with Er: YAG laser (160 mJ, 10 Hz). Second group: 15 patients (27 implants) were treated with Er: YAG laser in combination with photodynamic therapy (7.3 W, 690-905, 60, in combination with toluidine blue). PDT was used immediately after laser purification and removal of granulation tissue. After that, bone plastics were made on the surface of the implant. Depth pockets, level of gum attachment and X-ray examination data were evaluated before treatment and once a month for six months. Results and discussion: In both groups, the treatment results were positive: decreased pocket depth, gum attachment and no bleeding during the sensation, bone structure restoration. In the first group, in 80% of patients, a complete positive result was evaluated in 5-6 months.

10:00 – 10:45 Low power diode lasers – invasive application in everydays’ dental work
Dr Götz Gergely

In the dental daily routine the marginal gingival tissues have to be reduced, recontoured or sometimes more invasively cutted. For these purposes there are several, well known „old fashioned” treatments done by scalpels, electro-surgical devices, rotocurettage etc. But they are multi sessioned, not every time predictable treatments – especially in visible gum tissues. The soft tissue diode lasers (N/V  and SOL diode lasers) are able to make the time and sessions uniquily reduced, causing less postoperative pain and complications. These features can be succesfully combined with biocompatible, restorative materials such as Geristore. The proper usage of the N/V or SOL laser can support the hard and soft tissue regeneration especially in the marginal gum tissues. They can be really helpful for the dentists furthermore meet the patients requirements and demands as well.

11:20 - 12:00 A modern approach by Er:YAG Laser for the treatment of caries disease
Prof. Roly Kornblit

The dental caries, a disease process with multifactorial etiology where the bacterial assumes an important role, is still the most common pathology in dentistry. The traditional approach of the restorative dentistry was removing the decayed tissue using mechanical or manual instruments and the reconstruction of the residual tooth with different materials following functional requirements. The Minimally Invasive Dentistry (MID) approach in caries removal is to stop the disease process and to restore lost tooth structure and function, maximizing the health potential of the tooth. A modern, alternative approach can be, instead focused on a different management of the caries disease, taking in consideration not only the elimination of the decay but also a way to treat the infection. The Er:YAG laser that is used today in dentistry, can represent a different therapeutic modality, for the treatment of the caries infection. The Er:YAG laser treatment possesses the requirements of Minimal Invasive Dentistry: the possibility to ablate small area of infected layer guarantees maximum conservation of the tooth structure; the antibacterial property of the Er:YAG laser can guarantees the decontamination of the affected layer that retains its remineralisation potential; the lack of smear layer after laser vaporization assures a better retention of the composite resin to the dentine. Moreover, the bio stimulation effect, the tissue selective ablation, the low penetration deep are other Er:YAG laser properties that guarantees better results in Laser caries treatment. As for the restoration of the tooth structure with adhesive modern materials it is important to choose the correct enamel and dentin adhesive system in order to optimize the enamel-dentin surface bonding after Er:YAG laser preparation.

12:05 - 12:50 A laser solution to peri-implantitis problem
Dr Ilay Maden

Peri-implantitis has been an issue now making dental surgeons to think twice before starting an implant treatment - or at least, it should. While there are more than 60 variables that may lead to peri-implantitis and affect the treatment, there are some problematic situations which can be corrected with the help of the lasers. Disinfection of the rough surface of the implant, peri-implant area and improving the healing potential are some solutions lasers can offer. All this needs to be done without any change on the surface area, or that has been the approach until now. Even though laser is not yet the magic want we could wish it to be, it can help prepare a very good environment for healing in a very challenging clinical situation. The lecture will present an overview of periimplantitis, show what role lasers can play, summarize relevant literature and show clinical cases.

15:50 - 16:35 SEM surface observations of titanium implants irradiated by Er.Cr:YSGG laser – is there a possibility to treat Periimplantitis
Prof. Norbert Gutknecht

Unintended alteration of oral implant surfaces i.e. micro fractures, melting and ablation has been reported as a consequence of incorrect settings and handling of erbium-laser and diode laser of different wavelength. The aim of this pilot study was to compare the 2-dimensional surface structure by Scanning Electron Microscope of an untreated oxidized titanium oral implant surface. Material and methods : NobelBiocaretitanium dental implant representing an oxidized surface Laser equipment: Er,Cr:YSGG 2780 nm laser ; Hand piece for fibre tip: MZ8, 6 mm length, Diameter of fibre tip-end: 800 micrometer. Distance between fibre tip end and implant surface: 0,8-1,2 mm Laser parameters: 0,75W, 1,0W, 1,25 W, 50Hz, Water 80%, Air 20%, Fluency 6.25 J/cm2 , Analysis Field emission Scanning electron microscope (SEM) Jeol JSM-7400F was used for 2-dimensional surface observations. Results SEM results after irradiations following adjusted protocol: laser irradiation parameters at 1 mm distance and Er;Cr:YSGG settings of 0,75 W and 1,0 W no signs of alteration of TiU surfaces was observed. The surfaces seemed similar to non-irradiated control areas. After distance increasing from 1 to 2 mm the same observations was made for 1,25 W.
