UNLABELLED The occlusal surface is the most affected area by dental caries and the sealing of the pits and of the fissures has been found , in time , the preventive method most effective trying to counteract the onset .
Currently , the WHO considers it as a primary preventive measure , in other words one of the most effective and least invasive available to ensure the complete protection and the total preservation of the occlusal carious by the phenomenon .
PURPOSE THE AIM OF THIS WORK HAS BEEN TO PERFORM A SYSTEMATIC REVIEW OF THE LITERATURE ON CLINICAL TRIALS OF DIFFERENT SEALING MATERIAL S , IN ORDER TO : compare their individual characteristics , highlight the reliability and the long-term efficacy and identify the most significant variables , both technological and clinics , in order to declare whether or not the success of this method prior .
Randomized, controlled trial comparing the retention of a flowable restorative system with a conventional resin sealant: one-year follow up.
UNLABELLED This clinical trial evaluated the retention rate of a flowable restorative system ( Bond 1 + Flow-It ! ) used as a pit- and -fissure sealant compared with a conventional filled resin sealant ( Fluroshield ) over a 1-year period . METHOD Using a half-mouth design , 160  sealants  ( 80 in primary and 80 in permanent teeth ) were placed on sound first/second primary molars and first permanent molars of 40 children aged between 4 and 7 years . For both primary and permanent dentitions , half the teeth ( n = 40 ) were sealed with Fluroshield and half ( n = 40 ) with Bond 1 + Flow-It ! Teeth were evaluated at baseline , 6- and 12-month intervals . RESULTS For both material s , there was no total loss of sealants placed on either the primary or permanent molars over 1 year . From Fluroshield sealants placed on primary teeth , 33 were completely intact after 6 months and 31 after 1 year . From those placed on permanent molars , no loss of material was observed after 6 months , while partial loss was noticed on 5 % of teeth at 1-year recall . For Flow-It ! resin applied on primary molars , partial loss of material was observed in only 1 sealant after 6 months and in 2 sealants after 1 year . On permanent teeth , 100 % retention rate was observed over a 1-year follow up . There was a statistically significant difference ( P < 0.01 ) between the sealing material s on primary but not permanent teeth , and , overall , Flow-It ! sealants presented a higher retention rate at both 6-month and 1-year evaluations . Significant differences ( P < 0.01 ) between baseline and the other evaluation periods were also observed . CONCLUSION It may be concluded that the flowable restorative system yielded optimal retention on both primary and permanent molars . Its retention rate was significantly higher than that of the conventional pit- and -fissure sealant on primary teeth
