Summary

Evaluating the clinical behavior of composite restorations in NCCLs when the surface is pre-conditioned using bioactive glass air-abrasion has not been reported in the dental literature. This double-blinded randomised clinical trial evaluated the effect of surface pre-conditioning with bioactive air-abrasion on the performance of composite restorations in NCCLs placed using etch\&rinse and self-etch adhesive systems.

Conditions

  • Cervical Lesion

Interventions

PROCEDURE

Air-abrasion

A clinical air-abrasion unit was used to pre-condition the NCCLs with bioactive glass 45S5 powder for 10 sec. The operating parameters were; air pressure, 20 psi; powder particles size, 20 µm; nozzle angle, 90◦; nozzle-lesion distance, 5 mm and the internal nozzle diameter, 900 µm

PROCEDURE

Adhesive application - Etch&rinse

Enamel and dentine were etched using 37% Phosphoric acid for 30 sec and 15 sec respectively. NCCLs were rinsed thoroughly for 20 sec to remove the acid. Excess water was removed using a cotton pellet to leave a moist dentine surface. One coat of bonding adhesive was gently scrubbed on the entire enamel and dentin surface for 20 sec, air dried for 5 sec and light cured for 10 sec using LED curing light. The light intensity of curing unit was calibrated daily using curing radiometer .

BIOLOGICAL

Adhesive application - Self-etch

The bonding adhesive was applied to enamel and dentine for 20 sec with agitation, gently air dried and light cured for 10 sec.
