Numerous studies have been conducted on sealant retention
Four-handed dental procedures using strict isolation including dental dams, coupled with strict adherence to manufacturer's recommendations during sealant placement were used, which may have significantly impacted sealant retention
6) Although some authors have suggested that application of adhesive systems can improve marginal adaptation and retention of fissure sealants, (7) others have argued that this procedure offers no benefits to sealant retention
or marginal integrity.
Comparison of three different preparation methods in the improvement of sealant retention
Surface conditioning and the organic structure of the sealant may be factors that influence sealant retention
and dental caries status of all teeth were evaluated at 1 month, 6 months, 1 year and 2 years after sealant application under normal clinical conditions with a dental operating light, mouth mirror, and sharp dental explorer.
Improved sealant retention
with bonding agents: a clinical study of two-bottle and single-bottle systems.
Six months after the sealants were placed, 85% of the children were available to be examined for sealant retention
and caries development after resealing on first permanent molars of low, moderate and high caries risk children.
Overall sealant retention
for both fluoridated and non-fluoridated teeth at 6, 12, and 18 months was 68%, 48%, and 49%, respectively.
High initial caries risk showed significantly lower sealant retention
rates and higher occlusal caries prevalence following sealant loss, compared to those of low risk.
Simonsen[37,38] studied sealant retention
using a retrospective case-control study of children with permanent molars.
