Efficacy of a moisture-tolerant material for fissure sealing: a prospective randomised clinical trial
Fissure sealings offer nearly complete protection against fissure caries, provided that they are adequately applied, for composite-based sealants with sufficient moisture control. This is not always attainable, particularly in children with low compliance. To counter this problem, a moisture-tolerant sealant has been developed. The present randomised clinical trial compared such a moisture-tolerant material (Embrace) with a conventional sealant (Helioseal).
Material and methods
In 55 participants (mean age, 10 ± 3 years), corresponding molar pairs were sealed with either Embrace or Helioseal. Retention, quality of sealing, and caries were clinically examined, both tactilely and visually, immediately and after 1 year.
After 1 year, 93 % of Helioseal sealings were complete, whereas 60 % of Embrace sealings showed partial and 13 % complete loss. The surface quality of Embrace was significantly worse than that of Helioseal. After the use of Embrace, the sealant margin was noticeable as a slight (distinct) step in 36 % (15 %). The visual (tactile) examination showed a rough surface in 78 % (33 %) in the case of Embrace. The Helioseal surfaces were shiny (smooth) in all cases (all differences between Helioseal and Embrace, p ≤ 0.001). Caries was found only after the use of Embrace (4 %, n.s. compared to Helioseal).
The moisture-tolerant material Embrace was distinctly inferior to Helioseal because Embrace showed weaknesses in retention and surface quality.
Even if a moisture-tolerant sealant would be desirable in particular for children with low compliance, the tested material does not represent an alternative to the standard preparation.
