Title |
Light-Cured Resin-Based Sealants Have a Significantly Higher Long-Term Retention Rate than Fluoride-Containing Light-Cured Resin-Based Sealants |
Clinical Question |
In a patient with susceptible pits and fissures, do light-cured resin-based sealants (LRBS) have a higher long-term retention rate than fluoride-containing resin-based sealants (FRBS)? |
Clinical Bottom Line |
LRBS have a higher long-term retention rate than FRBS, and the difference in retention rates is greater as the time length is increased. |

#1) 22137936 | Kuhnisch/2012 | Patients with susceptible pits and fissures. | Meta-analysis of clinical trials and field studies | Key results | At 24 months, there was not a significant difference in retention rates between LRBS and FRBS (77.8% CI: 64.3-88.9 versus 81.1% CI: 45.8-97.8, respectively). At 60 months, LRBS had a significantly higher retention rate than FRBS (83.8% CI: 54.9-94.7 versus 69.9% CI: 51.5-86.5, respectively). | #2) 16948671 | Muller-Bolla/2006 | Permanent molars in patients ≥ 5 years old. | Meta-analysis of clinical trials | Key results | At 12 months, there was no statistical difference between LRBS and FRBS (RR = 1.01, 95% CI: 0.96 – 1.06). However, at 48 months, LRBS had a significantly higher retention rate than FRBS (RR = 0.80, 95% CI: 0.72 – 0.89). | |

Comments on
The Evidence |
In the Kuhnisch study, 110 clinical reports were included in the meta-analysis, of which 49 of the trials used a randomized process for allocating teeth with a certain material. Only studies that lasted at least two years were included in the analysis. No competing interests were found.
In the Muller-Bolla study, 9 clinical reports directly compared light-cured resin-based sealants to fluoride-containing resin-based sealants, 5 of which were randomized clinical trials and 4 were controlled clinical trials. Follow up ranged from 8 months to 54 months. |
Applicability |
The results are applicable to patients needing pit and fissure sealants. Authors of the Muller-Bola study determined that not only do FRBS have a lower long-term retention rate than LRBS, but also that multiple clinical reports show that the fluoride release is not significant enough to provide any clinical benefit. |
