Abstract
In this study where freshly extracted teeth were used, enamel lamellae were only found on the surfaces other than the occlusal. Contrary to previous studies there was no evidence of lamellae extending to the base of pits or fissures on the occlusal surface from other surfaces. This finding conflicts with a widely known view that lamellae play a role in pit and fissure cariogenesis and suggests, therefore, that the caries susceptibility of pits or fissures has no relationship with lamellae by nature.
