Facial image scale scores among the studied groups

Facial image scale	Polymer bur group	Carisolv group	Conventional group	p value
Median (Min–Max)	1 (1–3)	1 (1–3)	2 (1–5)	0.015*
MW test	P1 = 0.691, P2 = 0.028*, P3 = 0.01*

MW: Mann–Whitney test

P1: Comparison between polymer bur group and Carisolv group (non-significant difference)

P2: Comparison between polymer bur group and conventional group (significant difference)

P3: Comparison between Carisolv group and conventional group (significant difference)

Data expressed as median (minimum–maximum); p, probability; *, significance < 0.05
