Sealant: An In-Vitro Pilot Study

Aims and objectives: The aim of this in vitro study was to evaluate self-adhering composite Dyad flow (Kerr, USA) as a pit and fissure sealant. The objectives were to assess the degree of microleakage with self-adhering composite Dyad flow and that with Fissurit F as pit and fissure sealants and, to compare the same between these two materials. Materials and Methods: 20 premolars extracted for orthodontic purpose with intact occlusal surfaces were selected for the study. These were divided randomly into two groups, group A and group B, of 10 teeth each where Fissurit F and Dyad flow were used respectively as pit and fissure sealants. After enameloplasty was carried out, respective sealants were applied to the teeth of both the groups according to the manufacturers’ instructions. The teeth were then thermocycled and subjected to 1% methylene blue dye penetration for 24 hours, and sectioned mesio-distally. Microleakage was evaluated by observing degree of dye penetration under a stereomicroscope, and data was subjected to statistical analysis, using Mann-Whitney U test. Results: The results showed that the difference in scores of microleakage between Fissurit F and Dyad flow was not statistically significant. Conclusion: The conclusion of this in vitro pilot study was that both, Fissurit F and Dyad flow performed similarly as a pit and fissure sealant when evaluated in terms of microleakage. Thus, Dyad flow could be further evaluated in terms of clinical parameters as a pit and fissure sealant.
