Table 2.

Incidence of dentigerous cyst according to the thickness of the pericoronal radiolucency area (mm)

Thickness of the radiolucency area (mm)	Cysts		Incidence
	Yes	No
0–1	0	33	0.00%
1–2	2	17	10.53%
2–3	7	10	41.18%
3–4	5	2	71.43%
Total	14	62	18.42%

With the increase in thickness of the radiolucency area, the incidence of tooth cysts was significantly increased (χ² = 27.186, p < 0.05)
