Aktuelle Ausgabe laser (english)

In cooperation with the World Federation for Laser Dentistry (WFLD), the magazine laser: international magazine of laser dentistry addresses all dental professionals worldwide using or interested in dental laser technology. Readers receive regular updates on the world of international laser dentistry by means of user-oriented case studies, scientific reports as well as summarised product information. The magazine is particularly focussing on reports from international scientific congresses and symposia as well as on the international activities of the World Federation for Laser Dentistry. This high-gloss English language magazine is published four times a year. Since 2015, additional German-speaking abstracts have given an overview about each article’s content. News articles in German complete the new function of laser as the official magazine of the DGL in Germany. laser thus has replaced Laser Journal, which had appeared in 17 annual volumes of four issues until the end of 2014.

Editorial: Together towards a bright future
Author
I believe that all of us dental laser users worldwide would love to see a bright future for laser dentistry. Your participation in our upcoming International Society for Laser Dentistry (ISLD), German association for laser dentistry (Deutsche Gesellschaft für Laserzahnheilkunde?DGL) and World Academy for Laser Education and Research in Dentistry (WALED) congresses, to be held from 6 to 8 June in Plovdiv in Bulgaria, is essential for strengthening not only the ISLD but also the participating national societies, which are constantly striving to enrich the knowledge of their members and to promote professional excellence in the use of dental lasers through research and education...

Use of carbon dioxide lasers in dentistry
Dr Kenneth Luk1, Irene Shuping Zhao2, Prof. Norbert Gutknecht3 & Prof. Chun Hung Chu41 University of Hong Kong; 2 Shenzhen University Health Science Center, China; 3 RWTH Aachen University, Germany
“Laser” is an acronym that stands for “light amplification by stimulated emission of radiation”.1 The photons that make up a laser beam are coherent, amplified in phase (standing wave) and of a specific wavelength (monochro-matic). Laser has been used in dentistry for over two decades.2 Dental lasers are categorised according to their active medium and wavelengths. The currently available dental lasers are diode lasers (445, 635 and 810–980 nm), potassium titanyl phosphate lasers (532 nm, green), neo-dymium-doped yttrium aluminium garnet (Nd:YAG) la-sers (1,064 nm), erbium lasers (2,780 and 2,940 nm) and carbon dioxide (CO2) lasers (9,300 and 10,600 nm). Each laser wavelength has a specific thermal output and a particular tissue interaction...

Initial therapy of periodontitis using dental lasers
Dr Frank Liebaug, Germany
Gingivitis and marginal periodontitis are predomi-nantly bacterial diseases. Periodontitis is a chronic, multifactorial inflammatory disease caused by the accumulation of bacterial biofilm on the tooth surface. It is promoted by an impaired local and/or systemic immune response.1 Clinically, therapy must primarily have an antiinfective character. The reduction or elimination of this infectious disease is usually carried out by mechanical treatment of the affected tooth and root surfaces of the gingival pockets and adjacent soft tissue. Possible in-dividual risk factors of the patient must be identified and eliminated as far as possible. In special cases, local or systemic antibiotic support is indicated.2 ...

Treatment of oral leukoplakia with a 980 nm diode laser
Dr Maziar Mir, Prof. Norbert Gutknecht, Dr Masoud Mojahedi, Germany; Dr Jan Tunér, Sweden & Dr Masoud Shabani, Iran
Leukoplakia is a common precancerous lesion of the oral cavity. It is defined as “a predominantly white lesion of the oral mucosa that cannot be characterised as any other definable lesion”.1–3 Clinically, leukoplakias are divided into homogenous (a thin, flat and uniform white plaque with at least one area that is well demarcated, with or without fissuring) and non-homogeneous lesions that are characterised by the presence of speckled or erythroplakic and nodular or verrucous areas.4 Various non-surgical treatments (including the use of carotenoids [beta-carotene, lycopene]; vitamins A, C and K; fenre-tinide; bleomycin; photodynamic therapy) and surgical treatments (including cryosurgery, electrocautery, la-ser ablation) have been reported.5 This article presents successful results of oral leukoplakia treatment with a 980 nm diode laser...

Facial swelling caused by infected teeth
Dr Imneet Madan, UAE
Primary teeth retain their position in children’s mouths until they reach the age of 10 to 12, when molars exfoliate. Until then, it is vital for primary teeth to stay cavity-free and in a healthy condition. A mindset that we encounter quite commonly is that primary teeth do not necessarily need to be treated, as they are to fall out anyway. Yet, the contrary is true: it can be argued that primary teeth play a vital role in paving the way towards healthy permanent dentition...

Peri-implant bone regeneration through laser decontamination
Prof. Wilfried Engelke, Dr Christian Engelke, Germany; Dr Victor Beltrán, Chile & Dr Marcio Lazzarini, Germany
The recently published S3 guidelines of the German Association of Oral Implantology (DGI) and the German Society of Dentistry and Oral Medicine (DGZMK) state that peri-implant infections can be categorised into peri-im-plant mucositis and peri-implantitis.1 In peri-implant mucositis, only the supracrestal soft-tissue interface is involved; in peri-implantitis, the bony implant site is also involved.2 Smoking is the main risk factor for peri-implant mucositis, but it is likely that there are further contributing factors, such as cement residue, diabetes mellitus and sex.2 The development of peri-implantitis is particularly favoured by a history of periodontal disease, smoking and interleukin-1 polymorphism.4, 5 The main diagnostic criterion for distinguishing peri-implantitis from peri-im-plant mucositis is the lack of reversibility of the condition. Peri-implantitis can be characterised by putrid secretion, increasing probing depth, pain and radiographic bone resorption. Implant loosening requires a high degree of bone resorption in the case of peri-implantitis. Microbiological tests are rather unspecific regarding peri-implant mucositis and peri-implantitis...

A look back at the 17th International Congress of ISLD in Plovdiv
Dr Dimitris Strakas, Greece & Dr Georgi T. Tomov, Bulgaria
The annual congresses of the International Society for Laser Dentistry (ISLD), which was formed 31 years ago, have always been considered important scientific gatherings for dental laser enthusiasts from all around the globe. Following the successful congresses in Thessaloniki in 2017 and Aachen in 2018, which brought about a new congress era, the historic and beautiful Bulgarian city of Plovdiv was chosen as this year’s venue for the 17th International Congress of ISLD, held from 6 to 8 June 2019...
