  DEFINITION The Atraumatic RestorativeTreatment (ART) is a procedure based on removing carious tooth tissues using hand instruments alone and restoring the cavity with an adhesive material.
• 4.
  INDICATIONS Atraumatic restorative treatmentis carried out : • Only in small cavities( involving dentine) • In those cavities that are accessible to hand instruments.
• 5.
  CONTRAINDICATIONS Scanned with OKENScanner ART should not be used when: There is presence of swelling (abscess) or fistula near the carious tooth. The pulp of the tooth is exposed. Teeth have been painful for a long time and there may be chronic inflammation of the pulp.

  Essential Instruments andMaterial • MOUTH MIRROR : The instrument is used to reflect light towards the field of operation in order to view the cavity indirectly and to retract the lip, cheek and tongue. • EXPLORER : The instrument is used to identify the depth of caries. • TWEEZER: The instrument is used to carry cotton rolls, wedges and articulating paper from the tray to the mouth. • Spoon Excavator: The instrument is used to remove soft dentinal caries.
• 7.
  • DENTAL HATCHET:Used for widening the entrance of cavity. • CARVER: Blunt end is used for inserting the mixed glass ionomer into the cleaned cavity and into pits and fissures. The sharp ends is designed to remove excess restorative materials and to provide shape to the glass ionomer. • PETROLEUM JELLY: The material is used to keep moisture away from the glass ionomer restoration and to prevent the examination gloves from sticking to glass ionomer and gets hard. • COTTON WOOL ROLLS: They are used to absorb saliva so that the tooth to be treated can be kept dry.
• 8.
  ARRANGEMENT IN THEMOUTH • A very important aspect for ART is the control of saliva around the tooth to be treated. • Location in the mouth and method of placement of cotton roll is: • Upper Teeth: Retract the lip and cheek with mouth mirror to make space for the placement of cotton roll. Place the cotton roll in position with a slight rotating action from the tooth towards gingiva. This will prevent the cotton roll from coming out easily. • Lower Teeth: Ask the patient to stick the tongue out. Push the tongue aside with the mouth mirror. Place a cotton roll on each side of the floor of mouth. Then ask the patient to retract the tongue back to its normal position.

  PROCEDURE FOR ART •The tooth is isolated with cotton rolls. • The tooth surface to be treated is cleaned with cotton pellet • The entrance of the lesion is slightly widened by hand instrument to remove overhanging unsupported enamel rods with enamel hatchet. • The dental caries is removed by using either the small or medium sized spoon excavator. • If necessary, provide pulpal protection by calcium hydroxide. • The cavity surface along with occlusal margins are cleaned. • The cavity is acid etch. • Glass ionomer cement is mixed.
• 10.
  • The mixedglass ionomer is inserted into cavity and slightly overfilled. • A gloved finger which is smeared with petroleum jelly is pressed on top of the entire occlusal surface and slight pressure is applied. • The bite is checked. • Excess material is removed with a sharp carver. • The bite is rechecked and all high points are removed. • The filling is covered with petroleum jelly or varnish may be applied. • The patient is instructed not to bite with the tooth for at least half an hour.

  ADVANTAGES OF ART Easilyavailable hand instruments are used rather than the expensive electrically driven dental equipment's as it is a painless procedure the need of local anesthesia is eliminated. ART involves only the removal of decalcified tooth tissue which results in small cavities and conserve sound tooth structure as much as possible. The combined preventive and curative treatment can be done in one appointment. It is cost effective and less time-consuming procedure.

  DISADVANTAGES OF ART •Atraumatic restorative treatment procedure are not long lasting. • The average life is 2 years depending upon the rate of caries activity of individual oral cavity. • Because of lower wear resistance and low strength of existing glass ionomer materials their use is limited to small or medium sized one surface cavity only. • The continuous use of hand instruments over long period of time may result in fatigue. • A relatively unstandardized mix of glass ionomer may be produced due to hand mixing.
