Atraumatic Restorative Treatment (ART) using hand instruments caused less patient discomfort and conserved more tooth tissue compared to rotary instruments. The study supports ART as a truly atraumatic dental procedure.

Area of Science:

  • Dentistry
  • Dental Materials
  • Minimally Invasive Dentistry

Background:

  • Atraumatic Restorative Treatment (ART) utilizes only hand instruments for caries management.
  • The term ART suggests a procedure that is gentle for both patients and teeth.
  • Evaluating the actual atraumatic nature of ART regarding patient experience and tissue conservation is crucial.

Purpose of the Study:

  • To assess if Atraumatic Restorative Treatment (ART) is indeed atraumatic.
  • To compare patient discomfort levels between ART and conventional rotary instrument procedures.
  • To evaluate tooth tissue conservation differences between ART and conventional methods.

Main Methods:

  • A study involving 359 patients divided into two groups: hand instruments (ART) and rotary equipment.

  • Each patient received two restorations: one amalgam and one glass ionomer, without anesthesia.
  • Patient discomfort and preparation size were primary outcome measures.

    • Main Results:

    • Patients reported significantly less discomfort with the ART approach compared to rotary instruments.
    • Preparations made with hand instruments were smaller than those made with rotary instruments.
    • Discomfort correlated with preparation size, operator influence, and a patient-specific effect.

    Conclusions:

    • The findings support the designation of ART as an atraumatic restorative procedure.
    • ART demonstrates benefits in patient comfort and tooth tissue preservation.
    • Operator and patient factors significantly influence reported discomfort.
