Table 5.

Comparison of mean number of decayed tooth surfaces (ds > 0) between Navajo preschool children with and without a POQL event (total n = 928)

POQL event	With POQL event^*		Without POQL event^**		p value^***
POQL event	n	Mean ds (SD)	n	Mean ds (SD)	p value^***
Pain	215	10.1 (11.7)	713	4.8 (6.4)	<0.0001
Angry/upset	107	12.3 (14.9)	821	5.1 (6.5)	<0.0001
Cry	157	10.5 (13.3)	771	5.0 (6.4)	<0.0001
Worried	162	10.4 (13.1)	766	5.0 (6.4)	<0.0001
Trouble eating	156	9.4 (12.1)	772	5.3 (7.0)	<0.0001
Missed school/day care	58	8.0 (10.3)	870	5.7 (7.9)	0.11

With POQL event includes responses: all of the time, some of the time, once in a while

^**

Without POQL event includes responses: did not happen, do not know, refused

Unpaired t test of difference in mean number of decayed surfaces by event reported versus not reported
