Brief Summary

The purpose of this randomized clinical study was to evaluate the efficiency of Er,Cr:YSGG laser irradiation combined with a resin based tricalcium silicate material and calcium hydroxide (CH) in direct pulp capping for 3 months follow-up period.Sixty permanent vital teeth without symptoms and radiographic changes were randomly assigned to 4 groups (n=15): Gr 1: The exposed area was sealed with CH paste, Gr 2: The treated area was sealed with CH paste following Er,Cr:YSGG laser irradiation at an energy level of 0,5 W without water and 45% air, Gr 3: Resin based tricalcium silicate material (TheraCal LC) was applied directly to the exposed pulp, Gr 4: TheraCal LC was applied following irradiation with Er,Cr:YSGG laser.

Outcome Measures

Primary Outcomes (2)

  • Pulp vitality

    Pulp vitality is assessed with electric pulp tester as vital or non-vital

    3 months

  • Assessment of pain with questionnaire

    Pain assessment is carried out using the pain Numerical Rating Scale (NRS) with ratings between 0 to 9. No reactions to thermal stimuli and no tenderness to percussion.

    3 months

Secondary Outcomes (1)

  • Radiographic success

    3 months

EXPERIMENTAL

Direct pulp capping using Er,Cr:YSGG laser combined with resin based tricalcium silicate material

Other: Er,Cr:YSGG laser + TheraCal LC

Interventions

Exposed area was sealed with a self-hardening calcium hydroxide paste then final restoration was completed using a resin-modified glass ionomer and a nanohybrid composite resin

Also known as: Dycal, Dentsply, Tulsa, OK, USA
Calcium hydroxide

After the exposed area was irradiated with Er,Cr:YSGG laser at an energy level of 0,5 W, a repetition rate of 20 Hz, 140 µs pulse duration with 0% water and 45% air for 10 s, it was sealed with a self-hardening calcium hydroxide paste.Then final restoration was completed using a resin-modified glass ionomer and a nanohybrid composite resin

Also known as: Er,Cr:YSGG laser (Waterlase MD, Biolase, Irvine, CA, USA)
Er,Cr:YSGG laser + calcium hydroxide

TheraCal LC was applied directly to the exposed pulp with a needle tip syringe in incremental layers that was not to exceed 1 mm in depth. Then final restoration was completed using a resin-modified glass ionomer and a nanohybrid composite resin

Also known as: TheraCal LC, Bisco, Schaumburg, Illinois, USA
TheraCal LC

After the exposed area was irradiated with Er,Cr:YSGG laser at an energy level of 0,5 W, a repetition rate of 20 Hz, 140 µs pulse duration with 0% water and 45% air for 10 s, TheraCal LC was used to seal the treated area. Then final restoration was completed using a resin-modified glass ionomer and a nanohybrid composite resin

Er,Cr:YSGG laser + TheraCal LC
