Summary: | The aim of this study was to evaluate and compare for 24 months, the retention and surface characteristics of two pit-and-fissure sealants: Helioseal Clear and Helioseal F (Ivoclar Vivadent). The correlation between the different stages of eruption and sealant retention was also verified. Fifty children aged 6 to 8 years participated in the study, totalizing 153 teeth divided into two groups: HC (Helioseal Clear) and HF (Helioseal F). After 6, 12, 18 and 24 months, a clinical examination was performed by previously calibrated examiners. The surface characteristics and the retention of the sealants (modified RYGE & SNYDER criteria) were assessed. Analyzing the occlusal surface, HC exhibited a statistically significant higher retention at 12 (p=0.0345) and 24 months (p=0.0076). Concerning the surface characteristics, only the superficial discoloration of HC was smaller than HF, during the entire studied period. For all the other characteristics, the results of the Mann-Whitney test were highly significant at different periods (p=0.0000 to 0.0421). The frequency of air bubbles within the sealant surfaces, determined by Chi-square test, was significantly higher in HF (p=0.000:12 and 18 months to p=0.002: 6 and 24 months). HC sealant material exhibited the best performance regarding the retention and surface characteristics on the occlusal surface.
Resumo Os objetivos deste trabalho foram avaliar e comparar por 24 meses, a retenção e as características superficiais de dois diferentes materiais seladores, Helioseal Clear e Helioseal F(Ivoclar Vivadent). A correlação entre os diferentes graus de erupção e a retenção dos selantes também foram verificadas. Cinquenta crianças de 6 a 8 anos de idade participaram deste estudo, totalizando de 153 dentes divididos em dois grupos: HC (Helioseal Clear) e HF (Helioseal F). Após 6, 12, 18 e 24 meses, avaliação clínica foi realizada por dois examinadores calibrados. As caracterísiticas superficiais e a retenção (critério modificado de Ryge &Snyder) foram avaliadas. A análise da superfície oclusal, o HC demostrou retenção estatisticamente significante maior para os 12 meses (p=0,0345) e 24 meses (p=0,0076). Em relação às características superficiais, somente para descoloração superficial, o HC foi menor que do HF, durante o período estudado. Para as demais características, os resultados do teste de Mann-Whitney foram altamente significantes para HC em diferentes períodos (p=0,0000 a 0,0421). A frequência de bolhas nas superfícies seladas, determinada pelo teste do Qui-quadrado, foi maior e mais significante no HF (p=0,000:12 e 18 meses a p=0,002: 6 e 24 meses). O selante HC apresentou melhor desempenho à retenção e características superficiais. |
