laser (english)

Das in Kooperation der Deutschen Gesellschaft für Laserzahnheilkunde e.V. (DGL) und der 2018 gegründeten International Society for Laser Dentistry (ISLD) herausgegebene Magazin stellt sich in den Dienst des internationalen Know-how-Transfers in der Laserzahnmedizin. Analog zu dem seit 2000 sehr erfolgreich weltweit verlegten Magazin implants erhalten die Leser durch anwenderorientierte Fallberichte, wissenschaftliche Studien und komprimierte Produkt- und Veranstaltungsinformationen ein regelmäßiges Update aus der Welt der internationalen  Laserzahnmedizin. Einen besonderen Stellenwert haben in diesem Zusammenhang vor allem Berichte über die international stattfindenden Fachkongresse und Symposien sowie die internationalen Aktivitäten der DGL und ISLD. laser – international magazine of laser dentistry erscheint vierteljährlich und in englischer Sprache (BE).

Salivary flow rate before and after low level laser therapy
Sonja Pezelj-Ribaric, Natasa Grzetic, Miranda Muhvic Urek, Irena Glazar, Davor Kuis, Croatia
The therapy performed with lasers is often called low level laser therapy (LLLT) or just laser therapy. Several other names have been given to these lasers, such as soft laser and low intensity level laser whereas the therapy has been referred to as biostimulation. Low level laser therapy is a non-invasive, painless and athermal therapy, based on biological estimulative-regenerative, anti-inflammatory and analgesic effects. LLLT also appears to have a virustatic and bacteriostatic effect. Some explanation of analgesic effect of LLLT are: it increases ATP production, improves local microcirculation, increases lymphatic flow, increased serotonin and endorphins, increased anti-inflammatory effects through reduced prostaglandin synthesis.1
Effect of low level laser therapy during Rapid Maxillary Expansion
Eyad Hamade, Rwaida Saimeh, Mina Mazandarani, Maziar Mir/UAE, Norbert Gutknecht/Germany
Orthodontic tooth movement is the result of alveolar bone remodeling due to response to mechanical stimulus at the interface with periodontal ligament. Although Wolff’s law is generally considered to be a philosophical statement but states the effect that, over time, the mechanical load applied to living bone influences the structure of bone tissue. Bone remodeling can be categorized into two different types...
Minimally invasive dentistry (MID) concepts for the caries - teatment by Er:YAG laser
R. Kornblit, U. Romeo, A. Polimeni, Italy
The dental caries lesion is a bacterial infection created by cariogenic bacteria resulting in increased proportions of acid, producing consequently a low pH that produce a demineralization of the tooth structure.1,2 In the past, carious treatment approach was mainly a surgical removal of the infected tissue and the subsequent tooth reconstruction with a dental restorative material. At that time, diagnosis of caries lesions was carried out at more advanced disease stages than the incipient lesions detected today and instrumentation was limited to slow rotary and hand instruments...
Diode laser (810 nm) applications in clinical Orthodontics
Dr Deepak Rai & Dr Gurkeerat Singh, India
Dentistry has changed exponentially, osseointegration, dental bonding & kinetic energy tooth prepration are current clinical buzzwords. The arena of Dental Esthetics has expanded to cover more than just simply restoring compromised teeth, but involves revamping smiles in entirety. Soft tissue harmonization have become paramount to overall development of Dentofacial Esthetics...
Use of the Er,Cr:YSGG and Er:YAG lasers in restorative dentistry
Prof Dr Giuseppe Iaria, Rolando Crippa, Giovanni Olivi, Matteo Iaria, Stefano Benedicenti, Italy
The Er,Cr:YSGG laser has an active medium of yttrium-scandium-gallium-garnet doped with erbium and chromium ions and emits free-running pulsed laser energy at a wavelength of 2,780 nm. the Er:YAG laser has an active medium of yttrium-aluminium-garnet doped with erbium ions and emits free-running pulsed laser energy at a wavelength of 2,940 nm. These wavelengths have a high absorption in water, which makes their application appropriate when ablating oral soft tissue or dental hard tissue. This article examines the principles of use for the Er:YAG and Er,Cr:YSGG lasers in clinical restorative dentistry and reviews the literature regarding different aspects of the use of laser energy on hard tissues...
The use of lasers in periodontal treatment
Howard Golan, USA
There are some dentists that embrace technology. Technology can improve the delivery of dentistry and also help traditional dental philosophies evolve. For example, a patient presents with an emergency; a broken cusp on an upper bicuspid, bellow the free gingival margin. Technology, lasers and CAD/CAM specifically, allows the clinician to provide endodontics, osseous crown lengthening, an adhesive core build up and a definitive porcelain restoration all in a single appointment...
Photosensitizers in dentistry
Dr D. Koteeswaran, Dr C. Pravda and Dr Ekta Ingle, India
Photodynamic therapy (PDT), also known as photoradiation therapy, phototherapy, or photochemotherapy, involves the use of a photoactive dye (photosensitizer) that is activated by exposure to light of a specific wavelength in the presence of oxygen (Konopka et al.). The transfer of energy from the activated photosensitizer to available oxygen results in the formation of toxic oxygen species, such as singlet oxygen and free radicals. These very reactive chemical species can damage proteins, lipids, nucleic acids, and other cellular components. Depending on the type of agent, photosensitizers may be injected intravenously, ingested orally, or applied topically...
Annual Congress of DGL: A very successful 20th Annual Congress of the DGL in Berlin
Dr Georg Bach, Leon Vanweersch/Germany
More than 250 participants visited the yearly congress of the DGL, which was held together with the 14th LASER START UP, a symposium specially organized for new comers in the world of laser dentistry. Many dentists praised again this very nice concept of sharing two congresses in laser dentistry at one location, which was this year the Palace Hotel in the heart of Berlin...
Laser Safety Course: First year of AALZ Greece full of activities!
Dimitris Strakas, Greece
AALZ’s vision is to educate dentists from all over the globe and make them specialists in the field of laser dentistry. The AALZ educational programs are based on fundamental laser physics, neutral and objective information on current laser systems, skill training and evidence based description of dental indications. That is the reason that AALZ has become a synonym of quality educational programs amongst dentists who are willing to buy or already use a laser system in their clinic. As with many other countries that became again clear with Greek colleagues. In 2010 AALZ Greece was established by AALZ and RWTH Aachen University adjunct faculty members Dr Antonis Kallis and Dr Dimitris Strakas. In this first year many Greek dentists have participated in our programs and added their names to the long list of our students over the years...
