Diode laser surface decontamination in periodontitis therapy - 15 years of incorporating

Dr Georg Bach, Germany

We don’t always have the opportunity to provide long-term dental treatment for patients with a profound marginal parodontopathy who have undergone resective surgical therapy, at times including reconstructive work. Correspondingly, there is only a limited amount of literature available due to the aforementioned fact. The number of published studies/other publications is even more limited as regards new therapy concepts or adjuvant treatments to complement a proven therapy regimen. In 1995, the first diode laser (wavelength 810 nm) was presented at IDS in Cologne. This device—initially as a prototype—had been used within the scope of a test phase since 1994. At the end of 1994 patients were treated with this “new” laser wavelength for the first time, which had not been used in dentistry up until that time. The Freiburg laser work group led by Krekeler and Bach, who were the first ones to deal with the integration of diode laser light in dentistry, noticed the considerable advantages of this new technology...

Clinical comparison of two laser wavelengths - In the treatment of periodontal disease

Dr Ron Kaminer, USA

The use of lasers in everyday dental practice has grown steadily in the past ten years. Both Neodymium YAG (Nd:YAG) lasers and Diode lasers are routinely used in dental offices around the world for a variety of soft tissue procedures. In most clinical circumstances, a laser can offer well-defined benefits to the practitioner and patient...

The treatment of prominent frenulum with diode laser 940 nm

RedaktionDr Merita Bardhoshi, Albania

Labial frenectomy is a common surgical procedure in the field of oral surgery. Labial frenectomy is a procedure usually for orthodontic and prosdonthontic reasons. Diode laser are portable, compact, efficient, with good bactericid and coagulation properties. Diode laser have a wavelength between 810 and 980 nm. They can be used in the continuous as well as pulsed mode with a contact or non contact handpiece...

Photo-acoustic endodontics using PIPS

G. Olivi1, R. Crippa1, E. DiVito2,G. Iaria1, V. Kaitsas1 & Prof S. Benedicenti1

The goal of endodontic treatment is to obtain an effective cleaning and decontamination of the smear layer, including bacteria and all its products, in the root canal system. Clinically, traditional endodontic techniques use mechanical instruments as well as ultrasound and chemical irrigation in an attempt to shape, clean and completely decontaminate the endodontic system. The effectiveness of debriding, cleaning and decontaminating of all the intra-radicular space is, however, limited given the anatomical complexity and the inability of common irrigants to penetrate into the lateral canals and the apical ramifications. The complexity of the root canal system is well known. Numerous lateral canals of various dimensions and with multiple morphologies branch off from the principal canals. A recent study found the presence of these anatomical structures in 75 % of the teeth analyzed as well as the presence of residual infected pulp, after completion of chemo-mechanical preparation, both in the lateral canals and in the apical structures of vital and necrotic teeth associated with periradicular inflammation.1...

Paediatric laser--assisted dentistryA clinical approach

Claudia Caprioglio, Giovanni Olivi, Maria Daniela Genovese, Italia

The approach to paediatric dental patient demands close cooperation between dentist-parents and the child himself. Laser-assisted therapy is a modern and effective strategy. Laser technology has a wide application in dental care and treatment, oral traumatology and minor surgical procedures, and it’s suitable for the treatment both of primary and permanent teeth. The authors’ aim is to stimulate more extensive scientific research in this area and to offer a clinical overview, showing also some clinical procedures...

A concept of laser assisted treatment of periimplantitis

Dr Gérald Mettraux, Switzerland

Periimplantitis is a disease with growing incidence which when untreated, leads to the loss of the implant. The ethological factors of periimplant infections are similar to periodontitis. What about the treatment? Classical treatment procedures in closed periimplant pockets have shown little success (Renvert, 2008). In open flap procedures the treatment of periimplantitis shows more promising data (Lindhe 2008). Although we gain better access to the implant surface in open procedures, we encounter the same limitations as in open periodontal therapy. Nevertheless, decontamination of the implant surface is much more complicated than decontamination a root surface. The sophisticated implant surface which is so promising at the moment of insertion will turn into a death trap in case of pocket formation. The instruments used in periodontal treatment are much too big to get rid of the bacteria on the implant surface. The classic treatment procedures show very strict limitations and their instruments are not useful for adequate decontamination of the implant surface...

Esthetic rehabilitation of anterior hypoplastic tooth using Er:YAG laser

Dr Georgi Tomov, Bulgaria

Enamel hypoplasia (EH) is a defect in tooth enamel that results in less quantity of enamel than normal. The defect can be a small pit or can be widespread that the entire tooth is misshaped with affected mechanical properties.4 EH can occur on single or multiple teeth.6 It can appear white, yellow or brownish in color with a rough or pitted surface.6, 8 In some cases, the quality of the enamel is affected as well as the quantity.8 Environmental and genetic factors that interfere with tooth formation are thought to be responsible for EH. This includes trauma to the teeth, infections during pregnancy or infancy, poor pre-natal and post-natal nutrition, hypoxia, exposure to toxic chemicals and a variety of hereditary disorders.6

Laser-assisted teeth bleaching

Dr Dimitris Strakas, Greece

It is more than evident that in our every day practice, patients are asking for a whiter and brighter smile. Advertisements, movies, television shows and all kinds of media services, are centralized on the totally white teeth which seem to project ones health, well-being and beauty. As a profession we have learned that we have to deal not only with pain itself but also with the esthetics of our patients. For that reason many materials and techniques have evolved giving us the opportunity to implement it in our offices. Composite veneers, porcelain laminates all-porcelain crowns and teeth bleaching are some of them. Today the dental clinicians have to be capable and willing to offer esthetic interventions to their patients in order to be considered modern and up-to-date...

AALZ Hong Kong and China

Dr Ryan Seto

Laser Dentistry in Hong Kong and China is becoming more and more popular, especially because several Chinese companies are producing and selling very cheap diode lasers. Dentists are using now these diode lasers in their clinics, but unfortunately the companies do not train them. Education using laser therapy is a must and therefore we offer in Hong Kong and China laser courses and workshops, certified by AALZ and RWTH Aachen University...
