One Year Field Trial of a Fissure sealant Composed by Cyanoacrylate-polymethyl Methacrylate and Calcium Hydroxide Catalyst

applied cyanoacrylate-polymethyl methacrylate sealant to the pits and fissures of 1703 occlusal surfaces of 990 school children of 6 schools and the same numbers of opposite surfaces were left untouched as. a control. The different criteria regarding the caries and the sealing procedure among the va...

description applied cyanoacrylate-polymethyl methacrylate sealant to the pits and fissures of 1703 occlusal surfaces of 990 school children of 6 schools and the same numbers of opposite surfaces were left untouched as. a control. The different criteria regarding the caries and the sealing procedure among the various collaborators were well coordinated before the trial. Cyanoacrylate monomer and polymethyl methacrylate containing a suitable amount of calcium hydroxide were mixed on an acetate sheet and then the mixture was applied to an occlusal surface preconditioned by approximately 40% phosphoric acid. The caries reduction figure was obtained in comparison with different incidences of cavities produced on both the test and control teeth. The reductions in the caries incidence, 60.7 % after 6 months and 38.3 % after one yeaf produced statistically significant differences. Retention figures of the sealants were 76.7% after 6 months and 52.6% after 12 months respectively.
