Comparative clinical study of autopolymerized and light-polymerized fissure sealants: five-year results.

The retention of autopolymerized and light-polymerized Delton fissure sealants was compared. Sealants were applied to 207 first permanent molars with 304 separate sites in 73 children 6-8 years old (mean age 6.3 years). After five years, there was complete retention in 59% of the autopolymerized and 48% of the light-polymerized sealants. The resulting 11% difference in retention rates was not statistically significant at P less than 0.05.

Two-year evaluation in vivo and in vitro of Class 2 composites.

Nineteen class 2 Herculite restorations were evaluated two years after placement. Nine of these were retrieved and examined by clinical inspection out of the mouth. Six of the restorations were then removed and the cavities examined for extent and location of discoloration and secondary caries. Radiolucent defects at the gingival margins were seen in 36% of the teeth. Gaps were evident in 58% of the gingival margins of the retrieved teeth. Secondary caries was diagnosed in four cases, all of them at the cervical margin. Examination of the cavities after removal of the composite resin demonstrated the penetration of the carious process into the dentin.

An evaluation of marginal leakage of Class 2 combined amalgam-composite restorations.

Forty class 2 cavities were prepared in 20 permanent posterior teeth. In 20 cavities the gingival margin was placed in enamel and in the other 20 cavities in cementum. In every tooth one of the cavities was filled with composite and the other with a combined amalgam-composite restoration. Microleakage at the various interfaces was assessed by dye penetration. It was concluded that microleakage of the combined amalgam-composite restorations was significantly lower than that of the conventional composite restorations.

The retention of fissure sealants using twenty-second etching time: three-year follow-up.

The retention of a self-polymerized fissure sealant applied after twenty seconds etching time was evaluated after three years. From the original 100 molars that were sealed, seventy-one teeth with 105 sites were available. The sealants were totally retained in 91 percent of the cases, after three years. The findings demonstrate that the retention rates of fissure sealants using twenty seconds etching time are comparable to those reported with the more conventional sixty seconds.

Assessment of marginal leakage of class II amalgam-sealant restorations.

This study addresses the question of whether conservative methods of restoration may be applied efficaciously in permanent posterior teeth with proximal lesions and intact occlusal sealants. It evaluates the effect of in vivo experimental conditions on micro-leakage, using primary molars in this study, for information applicable to permanent molars.

Occlusal restoration using fissure sealant instead of "extension for prevention".

This study was conducted to determine the success of a conservative cavity preparation using the principle of "sealing for prevention" rather than cavity "extension for prevention". Three hundred and twenty one restorations were placed in 234 teeth of 110 subjects, ages six to fourteen, with a mean age of eight years. After three years, 273 restorations were examined. Caries appeared in ten teeth and sealant wear occurred in sixteen restorations. Complete sealant loss was observed in two restorations and partial loss in thirty-nine, leaving 224 restorations with complete retention of the sealant. These preliminary results demonstrate that conservative cavity preparation with sealing for prevention is a successful technique which conserves valuable tooth structure.
