Design outcomes

Primary

Measure	Time frame
The novel herbal cordless gingival retraction paste proposed in this protocol is designed to be biocompatible, cost-effective, and environmentally friendly, addressing limitations of existing commercial products. If the invitro and an inVivo results confirm adequate retraction and safety, this paste could provide a valuable alternative as gingival retraction material. Timepoint: Eligibility Check-Baseline Baseline Pre intervention assessment, clinical photographs, randomization. Intervention: Group A: Novel gingival retraction material (Day 1) Group B: Expasyl (Day 7) Group C: 3M ESPE paste (Day 14) Group D: No cord paste (Day 21) Control Group: Non impregnated cord (Day 28)	—
