MIH (molar-incisor hypomineralisation) is defined as hypomineralisation of systemic origin of one to four permanent first molars, often associated with the upper incisors (Weerheijm et al., 2001). The more molars that are affected, the greater the danger that the upper incisors will also have defects. Literature references on the prevalence of MIH vary.

The rehabilitation of an edentulous patient is always a challenge; it necessitates not only the replacement of lost teeth, but also the restoration of the entire underlying bone and tissue structures in order to create an overall aesthetic reconstruction and a good chewing function. Apart from the fact that the manufacture of complete denture prosthesis requires well-founded knowhow and great skill throughout all steps of the clinical and laboratory procedure, the selection of the teeth is in our opinion a decisive factor for the success of treatment. In this article we present the VITA MFT teeth assortment, which, as a multifunctional system, reliably achieves the functional and aesthetic characteristics upon which our patients place such great importance.

Particularly in the case of complex treatments, dental professionals sometimes tend to fail to recognize the importance of the temporary restoration, even though it assumes an important function in the treatment process. Apart from protecting the prepared teeth from infections and chemical and thermal influences, this also includes stabilizing the prepared teeth within the dental arch, securing the jaw relation as well as restoring, maintaining or correcting the function, phonetics, esthetics and shape. From a patient's point of view, the esthetic appearance of the temporary restoration is an important requirement, as they want to participate in social activities and smile with self-confidence also while wearing an intermediate restoration. Thanks to modern materials, this requirement can be met today.

The ability to create highly aesthetic direct composite resin restorations in a simplified manner has long been a goal for practicing dentists. In the past, difficulties with direct composite resins have included shade matching, handling properties, premature setting under operatory lights, and the overall ease of use. This article will describe a composite resin system (Amaris - VOCO) that has demonstrated desirable properties for use in both posterior teeth and especially in the aesthetic zone. A case report demonstrating the use of the material will be presented.

Delivering of oral health care in dental clinics or hospitals produces quantities of dental wastes which could cause hazardous problems to human and environment if these wastes are disposed improperly. The dental team members are responsible for the health of patients and the environment around. Proper handling of biomedical and dental waste management materials is an essential responsibility for the dental profession. Different types of dental wastes should be managed following the scientific documents and the local official rules. The dental wastes include infectious, non-infectious and normal wastes. These wastes include: amalgam particles, waste mercury, empty amalgam capsules, x-ray fixer, developer, x-ray cleaners, disinfectants, chemical solutions, lead foils, silver, heavy metals of crown and bridges and orthodontic, blood and oral fluids, sharps, pharmaceuticals and daily universal wastes.The main procedures to manage dental wastes are: Implementing the POLLUTION PREVENTION STRATEGIE, management of hazardous waste streams, and following the GENERAL REGULATORY REQUIREMENTS.

Restorations with veneers are becoming increasingly important. This is due in part to the modern cosmetic trend, which has permeated restorative dentistry for over 20 years. Traditional methods of fabrication for this type of restoration include the use of refractory die materials, pressable ceramics and more recently CAD/CAM technology. The platinum foil technique is an even older method. This article presents this highly skilled fabrication technique, step by step, using four cases and explains its possible indications in comparison with other options.
