Main Purpose: To determine if the presence or absence of fluoride plays a role in "hidden" pit and fissure caries

Overview of method of research: 515 participants age 15 in 1968-1969. Some were exposed to fluoridated water since birth - the others weren't. Clinical and radiographic examinations were performed, and lesions which were not detected clinically, but showed up on bitewing radiographs were considered hidden lesions. The authors hypothesized that fluoride had something to do with the presence of these hidden lesions.

Findings: The study showed that hidden caries is not a new phenomenon and that it is not directly attributable to the presence of fluoride. Fluoride, in fact, is found to reduce caries - including hidden ones.

Key points/Summary: Can the fluoride get deep down inside the pits and fissures?

Assessment of article: Okay for it's time
