Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
NCCLs meeting the inclusion criteria were randomly assigned into four experimental groups (n=25); A: air-abrasion + etch\&rinse, B: air-abrasion + self-etch, C: etch\&rinse and D: self-etch.
Prophylaxis was conducted using a rubber cup with pumice and water. The color of the composite was selected using VITA classical shade guide before applying local anesthesia with Lidocaine 2% with 1:100000 adrenaline. Retraction chord was inserted into the gingival sulcus with the aid of a blunt spatula without excessive pressure to the periodontium. Teeth were isolated with rubberdam. No preparation or beveling of cavosurface margins was performed to the NCCLs.
In air-abrasion groups, 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
For the etch\&rinse groups, 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 ( output \>800mW/cm2).
In self-etch groups, the bonding adhesive was applied to enamel and dentine for 20 sec with agitation, gently air dried and light cured for 10 sec.
NCCLs were restored using FiltekTM Z250 XT resin composite, placed in 2 mm increments and light cured for 20 s per increment. Final contour was achieved with a fine diamond rotary instrument followed by finishing and polishing using Optrapol polishing kit .
Clinical evaluation was conducted by two trained and calibrated examiners. The examiners and patients were blinded to the group assignment, in accordance with the double-blinding randomized clinical trial design. Each restoration was evaluated at baseline (one week after restoration placement), 3 months and 6 months. This evaluation was conducted according to World Federation criteria (FDI)
