Penetration of acid solution and gel in occlusal fissures.

This study evaluates the penetration of an acid solution and two gels with different viscosities into occlusal fissures. Morphologically distinguishable differences in enamel at the occlusal site was examined as to whether the tooth is treated by acid solution, low-viscosity acid gel, or high-viscosity acid gel as well as the extent of involvement, using either a conventional or scraping method of application. The study also looks at the use of a gel acid agent in the pit and fissure sealant treatment.
