title: [Current trends in dental practice].
abstract: BACKGROUND
  This paper reviews recent trends in basic dental disciplines and advantages of new clinical procedures over conventional.
  Post and core restoration is one of the most common treatment modalities applied when the remaining coronal tooth structure is not sufficient to provide the necessary retention form for restoration. Nowadays, the restoration of endodontically treated teeth is based on the use of materials with a modulus of elasticity similar to that of dentin.
  Polymerization contraction stress of resin based composite during light-activation process may be reduced by various illumination schemes. Successful curing depends on the calculated energy density values (spatial irradiance x irradiation period - J/cm2) rather than on light irradiance levels (mW/cm2).
  It is well documented that various systemic diseases have a profound effect on periodontal tissues. Recently, it has been speculated that periodontal disease may influence systemic health and represent the risk factor for cardiovascular diseases or adverse pregnancy outcomes.
  Computer systems, which will automatically identify relevant skeletal and soft tissue roentgencephalometric landmarks, will represent a great improvement in the field of orthodontic diagnosis. By using the Active Appearance Model, it is possible to identify most of roentgencephalometric bony landmarks with an average error well below 2 mm.
  Chemomechanical caries removal was introduced as an alternative to conventional mechanical procedures. Its advantages are: selective removal of carious tissue, absence of pain, reduced need for local anesthesia and less potentially negative effects on the dental pulp.
  
  
  CONCLUSIONS
  The introduction of the surgical operating microscope, microsurgical instruments, ultrasonic retrotips for root-end cavity preparation and new root-end filling materials opened a new era in periapical surgery, even on multi-rooted teeth, often called endodontic microsurgery.
