Clinical/Photographic Evaluation of a Single Application of Two Sealants After Eleven Years

Abstract

The clinical behavior of Concise and Prisma Shield sealants for pit and fissure was analyzed by clinical/photographic evaluation. A hematoxylin-based staining solution was applied to the occlusal surface 7 days, 18 months, 36 months, and 11 years after the occlusal sealing, thus allowing the sealant material on the surface to be checked. At each analysis time, each occlusal surface was photographed, and the photographs corresponding to each time were submitted to clinical/photographic evaluation. Although the sealant materials showed marginal alterations over time, they did not require reapplication because the region composed of the pit and fissure remained covered.

Resin Tag Length of One-Step and Self-Etching Adhesives Bonded to Unground Enamel

“…Acid etching of dental enamel prior to application of a resin material considerably influences the durability of that material in the oral cavity. One such example is the accomplishment of pit and fissure sealants reported by Simonsen in 1991 17) and Sundfeld et al in 2004 19) , at 15 and 11 years after application, respectively. This was mainly due to the extremely accurate technique to which the sealing material was submitted, comprising application on etched, well-dried, and non-contaminated enamel.…”

Effect of Time Interval between Bleaching and Bonding on Tag Formation

“…This method is a clinically conservative, non-traumatic, biocompatible means by which resins, polymerizable under oral conditions, can be bonded durably to enamel 6) . In addition, the success of acid etching of enamel prior to the placement of adhesive materials has had a profound effect on the long-term behavior of those materials in the oral cavity 12,18) . It has been observed that when teeth with composite resin restorations are bleached, a color discrepancy is created which frequently requires the replacement of existing restorations 1,7,10,11,[13][14][15][16][17] .…”

Avaliação dos selantes de fossas e fissuras aplicados por estudantes de Odontologia

“…Alguns fatores são fundamentais para assegurar a retenção deste material na superfície dentária: morfologia das fossas e fissuras, propriedades físico-químicas do esmalte dentário, grau de limpeza da superfície dentária, viscosidade do material usado como selante e qualidade na técnica de aplicação [11][12][13][14][15][16] . O cuidado com a técnica merece destaque, na medida em que cada etapa do protocolo deve ser rigorosamente executada.…”

“…O cuidado com a técnica merece destaque, na medida em que cada etapa do protocolo deve ser rigorosamente executada. Exige-se que a superfície dentária esteja limpa, livre de umidade e adequadamente preparada para receber o material indicado para o selamento das fossas e fissuras [14][15][16] . Estes aspectos devem ser enfatizados aos estudantes e jovens profissionais, para que o protocolo seja executado com o máximo cuidado, evitando imperfeições que possam comprometer a longevidade do selamento.…”
