RESUMO
The purpose of this study was to evaluate the long-term retention and effect on caries rates of pit and fissure sealants containing fluoride (UltraSeal XT and FluoroShield). These sealants were placed in vivo on opposite sides of the arch in adolescent patients in a private practice. A total of 470 sealants were placed on permanent molars and premolars. After two years, 74.3 percent of the sample was available for recall. The total retention rate (Category A) was 96.3 percent for UltraSeal XT and 91.4 percent for FluoroShield. There were no new pit and fissure carious lesions over the two years of the study. The results for the UltraSeal XT is the highest retention rate yet documented.

The purpose of the study was to evaluate whether the clinical effectiveness of pit and fissure sealant was increased (as demonstrated by an increased retention rate) when a bonding agent was used prior to the placement of the sealant. Two pit and fissure sealants, Concise Light Cured White Sealant and Prisma Shield Light Cured Sealant, were placed in vivo with and without the use of the bonding agents, Scotchbond 2 and Prisma Universal Bond. After 2 years, 55% of the sample was available for recall. The retention rates for the sealants were 77% for Concise with Scotchbond 2, 84% for Concise with no bonding agent, 77% for Prisma Shield with Universal Bond, and 77% for Prisma Shield with no bonding agent. Results of this study indicated that the use of a bonding agent prior to the application of a pit and fissure sealant does not increase the retention rate.

Seventy-nine Class I and II light-cured composite resin restorations were evaluated for 3 years. Although the composite resin was not totally wear resistant, its overall clinical performance was acceptable, relative to most parameters of evaluation. The use of such a material in the posterior region may be justified in situations in which appearance is important, ideal circumstances predominate over conservative cavity design, and the patient understands the benefits and limitations of the procedure.

There is a good deal of current speculation that composite resin materials will shortly replace silver amalgam as routine posterior restoration systems. This article provides guidelines in the selection and clinical handling of the new generation high copper amalgam alloys.
