Title Penetration Depth of Flowable Nanocomposite as a Pit and Fissure Sealant in Children and Adolescents Is Greater Than Conventional Sealant Material
Clinical Question In children and adolescents, is flowable nanocomposite a comparable alternative to conventional sealants when evaluating penetration into deep pits and fissures?
Clinical Bottom Line For young patients with deep pits and fissures, flowable nanocomposite is more effective than conventional pit and fissure sealants in regard to depth of penetration. This is supported by an in vitro comparative study in which flowable nanocomposites produced a significantly higher mean percentage penetration than conventional pit and fissure sealants.

The Evidence
The extracted premolars were similar at the start and then were randomly placed into different groups, although they do not specify whether the groups were evenly balanced for maxillary and mandibular teeth; this could affect the results greatly as a result of variance in fissure anatomy. All three experimental groups were treated the same. Since this was a lab study, compliance, recall bias, and completion rate were not applicable. Although this in vitro study resulted in strong evidence for the use of flowable nanocomposite in terms of percentage penetration, long-term clinical studies are necessary to establish the more clinically relevant outcome of caries prevention with these materials.
Applicability The extracted premolars used in this study gave it limited applicability, since clinically the teeth most often sealed are molars. Although this study was also not completely representative of an actual clinical setting, more studies should now be done to compare the clinical effectiveness of these various materials. Nevertheless, this study was applicable in determining that flowable nanocomposite should be considered as a possible future alternative to conventional pit and fissure sealants, especially for pediatric dental patients with deep pit and fissure anatomy.
