Laser devices have gained in importance since the eighties and they are often claimed to be omni-use instruments. Though many applications turned out to be impracticable, an unwaning interest in this technique has remained to date. The broad spectrum of applications for the diode laser means that it is now the most widely used device in laser dentistry. Diode lasers offer an interesting - but not unlimited - field of application in modern dentistry including periodontology, endodontics and soft tissue treatment.

The fluorescence properties of dental tissue vary between different age groups of patients, as was discovered by the authors of this article, for example during one of their own studies. This observation must be taken into account above all when creating aesthetic restorations, as there is also wide variation in the fluorescence behaviour of restorative materials. A case study shows that dentists are well advised to pay sufficient attention to this aspect.

Now a new generation of materials for chairside treatment using CAD/CAM technology is available. The future of chairside CAD/CAM restoration may be VITA ENAMIC - a composite material that is unique worldwide in combining the benefits of conventional ceramic and composite materials. Both scientific studies and initial clinical experience confirm that with the VITA ENAMIC hybrid ceramic, a new dimension in stability, reliability, precision and cost-efficiency can be achieved.

A well-planned working protocol is an essential tool in the fabrication of dental restorations. The authors have developed a special approach in our dental laboratory. It is presented here on the basis of a case study. The restorative work involved the fabrication of six veneers for the anterior teeth. In cases such as the one described, veneers represent an excellent treatment option. Shown are outstanding results with restorations involving pressed frameworks, which were subsequently built up with ceramic layers. This method is much easier than the conventional layering technique, but nevertheless provides optimum quality.

In the case of fixed detachable dental prostheses some problems arose for patients, dental technicians and dentists. The most frequently emerging general problem is loosening or breakage of the occlusal screws. Further problems turned out to be wear and detachment or breakage of the resin teeth from metal acrylic blends, the breakage of porcelain from metal and ceramic or zirconia and ceramic blends as well as breakage of the framework in some free-end prostheses. For this type of prosthesis it is necessary to leave the implants in a position that enables occlusal or lingual access to not impair the aesthetics.

This clinical report describes the case of a patient with a complete restoration of fixed detachable, maxillary and mandibular prostheses out of 100% zirconia (monolithic zirconia). It includes the incisal and occlusal areas on angled dental implants with buccal access and an aesthetic prosthesis solution, for which no clinical complications in the patient's mouth have been reported after 4 years.

Amalgam is the most extensively used material in dentistry. There have been no clinical trials of this substance and there are no epidemiological studies that allow any conclusions on the safety of amalgam fillings. Amalgam restorations continuously emit mercury vapour, which is absorbed in considerable quantities via the lungs. Most scientific reports showed that amalgam fillings are safe and could be used in human to fill cavities, while some other reports and studies concluded that amalgam restorations are harmful for health and suggests that individuals with unusually high emission of mercury from amalgam fillings are at risk. Many dentists remove of amalgam fillings every day, with no regard for the possible mercury exposure that can result from grinding them out. Big caution and preventive procedures must be adopted when removing amalgam fillings to protect both dental operators and patients.

The introduction of tissue regeneration into periodontal therapy has brought fundamental changes to dental treatment planning and enabled new treatment approaches. By contrast, resective therapy to eliminate pockets has the reputation of an antiquated treatment method. This article will illustrate that the two techniques are by no means mutually exclusive and must often indeed be used in combination. Since periodontal regeneration depends greatly on optimal patient cooperation and the skill of the dentist and works predictably only with certain defects, the range of indications until today has been limited and is restricted to three-walled defects, deep twowalled defects and grade two furcations defects. On the other hand, pocket elimination is indicated only in early stages of periodontitis and serves to create physiological tissue architecture to prevent further bone atrophy. The present study summarizes the principles of and indications for regenerative and resective periodontal therapy and explains the conditions necessary for a successful treatment outcome to counteract unrealistic expectations of regeneration and avoid undesirable / unwanted / unintended consequences of pocket elimination.
