1.2 Rationale and Evidence for Programs

Tooth-Surface Risk Factors

Risk for Dental Caries

Tooth-Surface Risk Factors

About 90 percent of carious lesions are found in the pits and fissures of permanent posterior teeth.7

Tooth-Type Risk Factors

Among permanent teeth with pits and fissures, molars are the most susceptible to caries attack. Premolars are next, but there is a large gap in the dental caries rates of molars vs. premolars.7
