Effectiveness of Fissure Sealant in Preventing Caries in Children

Abstract

The main aim of this study was to evaluate the retention and effectiveness of fissure sealant Fisseal Extra (ProMedica, Germany) in prevention of caries in school children in Thamar, Yemen. Eighty five children aged 5- 12 years were selected randomly from different schools of Thamar and examined. Using a splitmouth design, the experimental teeth (maxillary and mandibular premolar and molar) were sealed with fissure sealant; while, teeth of another side of mouth acted as control group. The retention and effectiveness of sealant were carefully inspected after 1, 3, 6 and 9 months. The results revealed that, after 9 month, the retention and effectiveness rate was 98.3 and 96.9 percent respectively. Statistically, there was no significant difference between the different groups (P< 0.05). The fissure sealant showed high rate of retention and effectiveness and this could be useful in control and prevention of caries in school children.
