Goal of contemporary dentistry is to decrease the patient’s discomfort during
treatment. Dentists aim to achieve maximum with the newly developed dental
materials as well as with new cavity preparation techniques in the shortest
time span. Since the development of the first constructed borer (drilling
machine) for caries removal, the preparation techniques have considerably
changed. The progress of dental materials as well as the cavity preparation
techniques has led us to contemporary carbide tungsten and diamond borers
that are used with obligatory water cooling. The innovation within this field
represents newly developed polymer borers that can detect the difference
between carious lesions and healthy tooth structure. In this way the cavity
preparation may be performed without damaging dental healthy tissue. This is
possible owing to their hardness which is lower than the hardness of intact
dentin. Polymer borer preparation is painless with less vibration, while the
increase in temperature is negligible. Lasers have been used in clinical
dentistry since 1980s so it can be said that they represent a new technology.
The function of lasers is based on ablation which requires water. Erbium
lasers have shown the highest potential with their ability to produce
effective ablation of hard dental tissues. Laser application in dentistry
requires special training as well as some protective measures. Laser
advantages, compared to traditional preparation techniques, involve the
absence of vibration, painless preparation, possibility of preparation
without anesthetic and easier patient’s adjustment to dental intervention
which is of importance, especially in pediatric dentistry.
