NCT03080649

Brief Summary

The aim of this study was to evaluate the excavation time, patients´ experiences, pulpal reactions and survival of fillings when carious tissue was removed with Er:YAG laser compared to rotary bur. A prospective, single-blind, randomized and controlled investigation was performed. Patients with at least two primary caries lesions radiographically assessed as the same size were recruited. In each patient one cavity was excavated with rotary bur and one with Er:YAG laser technique. The time requested for excavation and local anaesthesia were measured. The prevalence of postoperative symptoms, pulpal vitality and the quality of fillings will be investigated during two years after the excavation occasion.

Eligibility Criteria

Age15 Years - 40 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • patients should be between 15 and 40 years,
  • at least two lesions with primary caries estimated as being of equal size, and needed to be treated, in bite-wing radiographs, and
  • comparable pairs of cavities should be located on either occlusal or approximal surfaces.
  • the lesions should not involve the inner third of the dentin.

You may not qualify if:

  • patients with severe general diseases ( ASA\>2) (30),
