NCT04578717

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Change in Restoration Retention Rate and Integrity

    The unabbreviated scale title: Restoration Retention Rate and Integrity Scale The minimum and maximum values: 1, 5 Higher scores mean a worse outcome. 1. Restoration retained, no fractures/ cracks 2. Small hairline crack 3. Two or larger hairline cracks and/or chipping (not affecting the marginal integrity) 4. Chipping fractures which damage marginal quality 5. Partial or complete loss of restoration

    Baseline (one week after restoration placement), Change from Baseline rate of retention at 3 months, Change from Baseline rate of retention at 6 months

Secondary Outcomes (4)

  • Change in Marginal Adaptation

    Baseline (one week after restoration placement), Change from Baseline marginal adaptation at 3 months, Change from Baseline marginal adaptation at 6 months

  • Change in Postoperative Hypersensitivity

    Baseline (one week after restoration placement), Change from Baseline postoperative hypersensitivity at 3 months, Change from Baseline postoperative hypersensitivity at 6 months

  • Change in Recurrence of Caries

    Baseline (one week after restoration placement), Change from Baseline recurrence of caries at 3 months, Change from Baseline recurrence of caries at 6 months

  • Change in Marginal Staining

    Baseline (one week after restoration placement), Change from Baseline staining margin at 3 months, Change from Baseline staining margin at 6 months

Study Arms (4)

Air-abrasion + Etch & rinse adhesive

EXPERIMENTAL

Air-abrasion unit was used to pre-condition the NCCLs with bioactive glass 45S5 followed by etch\&rinse adhesive application 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

Procedure: Air-abrasionProcedure: Adhesive application - Etch&rinse

Air-abrasion + Self-etch adhesive

EXPERIMENTAL

Air-abrasion unit was used to pre-condition the NCCLs with bioactive glass 45S5 followed by self-etch adhesive application which was applied to enamel and dentine for 20 sec with agitation, gently air dried and light cured for 10 sec.

Procedure: Air-abrasionBiological: Adhesive application - Self-etch

Etch & rinse adhesive

EXPERIMENTAL

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

Procedure: Adhesive application - Etch&rinse

Self-etch adhesive

EXPERIMENTAL

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

Biological: Adhesive application - Self-etch

Interventions

Air-abrasionPROCEDURE

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
