Median (min-max) values and statistical comparisons for decayed, missing, and filled teeth, DMFT index, and PI values in the PD group.

PD group	Uneducated and primary school median (min-max)	Secondary school median (min-max)	High school median (min-max)	𝑃
Missing	11 (0–30)	7 (0–32)	9 (0–23)	NS
Decayed	2 (0–7)	1 (0–7)	0 (0–7)	NS
Filled	0 (0–22)	3 (0–15)	6 (0–24)	𝑃<.001
DMFT index	14 (0–37)	13 (1–32)	16 (3–39)	NS
PI	2 (0.38–3)	0.95 (0.08–3)	1.23 (0.25–3)	𝑃<.01

PD group: Group of patients receiving peritoneal dialysis treatment; DMFT index: Decayed, missing and filled teeth index; PI: Plaque index; NS: Statistically not significant (𝑃>.05).
