An investigation of pit and fissure sealant retention in 1,871 children in the Head Start program was conducted in Tennessee in September 1985 to determine the retention of the sealant after application to the occlusal surfaces of primary molars of 3- and 4-year-old children. The investigation shows pit and fissure sealants are retained on primary molars at a rate comparable to that expected on permanent molars.
