Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
1. Retraction cord with astringent (RCA; Control group): Knitted cord impregnated with aluminum chloride (Ultrapak + Viscostat Clear; Ultradent Inc.)
2. Cordless paste with astringent (EXP): Expasyl (Acteon PVT LTD)
3. Cordless paste without astringent (MF): Magic FoamCord (Coltene Whaledent AG)
4. Laser troughing (LT): Diode laser (iLase; Biolase Inc.)
Digital impressions were obtained before and after retraction using a Trios 3Shape intraoral scanner. The gingival displacement was measured digitally, and scan accuracy was analyzed via RMS error. Bleeding index, finish line visibility, and patient discomfort (VAS) were also recorded.
