Abstract in Portuguese
Os objetivos deste trabalho foram avaliar e comparar por 24 meses, a retencao e as caracteristicas superficiais de dois diferentes materiais seladores, Helioseal Clear e Helioseal F ambos da Ivoclar Vivadente, AG - Schaan, Liechtenstein. Participaram desse estudo, 50 criancas de 6 a 8 anos de idade, com no minimo dois primeiros molares permanentes higidos e historia de carie, num total de 153 dentes divididos em dois grupos: GHC(Helioseal Clear) e GHF (Helioseal F). O selamento foi realizado sob isolamento relativo para todos os grupos, após profilaxia previa com jato de bicarbonato (Profident Dabi-Atlante) e agua e, condicionamento com gel de acido fosforico a 34% por 15 segundos. Apos 6, 12, 18 e 24 meses, a avaliacao clinica foi realizada por dois examinadores calibrados. Avaliou-se a retencao e a incidencia de carie nas 5 areas oclusais: OM, OC, OD, OV e OL (DEERY et al.) e; as caracterisiticas superficiais e a retencao considerando a superficie oclusal com o um todo (criterio modificado de RYGE &SNYDER).Nao houve diferenca estatisticamente significante atraves do teste exato de Fisher na taxa de sucesso (p=0,496 a 1,0) ou para a incidencia de carie (p=0,472 a 1,0) entre as areas avaliadas quando comparado o GHC com GHF durante todo o período estudado. Considerando todas as areas juntas e os grupos separados ou, os dois grupos juntos mas as areas separadas, nao houve diferenca estatisticamente significante, respectivamente, pelo teste de Fisher (p=0,170 a 0,534) e do Qui- Quadrado (p=0,058 a p=0,909), quanto ao sucesso na retencao em nenhum periodo. Quanto a analise da superficie oclusal toda quanto a retencao, esta foi maior e estatisticamente significante para o GHC aos 12m (p=0,0345) e 24m (0,0076). Em relacao as caracteristicas superficiais, o GHC so nao apresentou superioridade quanto a descoloracao superficial, durante o periodo estudado. Para as demais caracteristicas, os resultados do teste de Mann-Whitney foram altamente significantes em diferentes periodos (p= 00000 a 0,0421). A frequencia de bolhas nas superficies seladas, determinada pelo teste do Qui-quadrado, foi maior e significante (p=0,000:12 e 18 meses a p=0,002: 6 e 24 meses) no GHF. Portanto, pode-se concluir que quanto a retencao e caracteristicas superficiais, na superfície oclusal toda, o selante Helioseal Clear apresentou melhor desempenho.

Abstract in English
The objectives of this study were evaluated and compared for 24 months, the retention and surface characteristic of two different sealing materials, and Helioseal F Clear Helioseal both of Ivoclar Vivadent, AG - Schaan, Liechtenstein. 50 children from 6 to 8 years of age with at least with two sound first permanent molars and caries of history, total of 153 teeth, were divided into 2 groups: GHC (Helioseal Clear) and GHF (Helioseal F). The sealing was done with ruber dam for all groups, after prophylaxis with air-polishing jet (Profident --Dabi Atlante) and water, and acidetching with 34 % phosphoric acid 34% for 15 seconds. After 6, 12, 18 and 24 months, clinical evaluation was evaluated by two calibrated examiners. To evaluate the retention and the incidence of occlusal caries in 5 areas: OM, OC, OD, and OV OL (DEERY et al.). And, the surface characteristics and retention considering the all occlusal surface (modified criterion RYGE & SNYDER ). There was no statistically significant by Fisher's exact test in the rate of success (p = 0,496 to 1.0) or the incidence of caries (p = 0,472 to 1.0) between the areas assessed when compared with the GHC GHF throughout the study period. Considering all areas and groups together or separated, the two groups together but separate areas, there was no statistically significant difference, respectively, by Fisher's test (p = 0170 to 0534) and Chi-Square (p = 0,058 to 0,909), about the success in holding in any period. The analysis of the entire occlusal surface on retention, it was higher and statistically significant for the GHC to 12m (p = 0.0345) and 24m (0.0076). In relation to surface characteristics, the GHC showed superiority not only on the superficial discoloration over the period studied. For other characteristics, the results of the Mann-Whitney test were highly significant in different periods (p = 00000 to 0.0421). The frequency of bubbles in the sealed surfaces, as determined by Chi-Square was higher e statistically significant difference (p = 0,000:12 and 18 months p = 0,002: 6 and 24 months) in GHF. Therefore,the retention and surface characteristic in the all occlusal surface, the Helioseal Clear sealant showed better performance
