Means (±SD) of caries counts and surfaces at risk at each of the three examinations (156 subjects)

Parameter	Primary Dentition (Exam 1)	Mixed Dentition (Exam 2)	Permanent Dentition (Exam 3)

New Non-cavitated Caries (Surfaces)*
• All children	0.56 ±1.65	0.99 ±1.94	0.87 ±1.77
• Among children with new cavitated caries	2.67 ±2.73	2.54 ±2.40	2.41 ±2.25
% with New Cavitated Caries	26.28%	53.85%	27.56%
New Cavitated Caries (Surfaces)*
• All children	1.30 ±3.42	2.97 ±4.45	0.67 ±1.42
• Among children with new cavitated caries	4.95 ±5.17	5.52 ±4.77	2.42 ±1.76
Surfaces at Risk for Non-cavitated Caries**	86.81 ±3.78	110.73 ±5.26	123.01 ±11.83
Surfaces at Risk for Cavitated Caries***	86.81 ±3.78	111.22 ±5.27	123.53 ±11.70

^*New counts determined though age 5 for primary dentition exam outcomes, from primary to mixed dentition for mixed dentition exam outcomes and from mixed to permanent dentition for permanent dental exam outcomes.

^**Sound at previous exam.

^***Sound or non-cavitated caries at previous exam.

Note: new cavitated caries included both untreated and treated cavitated lesions.
