Abstract
This study was carried out to evaluate the clinical performance of the
conventional flowable composite resin restoration, using one- step adhesive system (Flow-It A with Bond versus the novel self-adhesive
flowable composite restoration (Fusio Liquid Dentin), over one year
evaluation period. An in- vitro study was, also, performed to compare the microleakage of both materials. As well as, the inspection of the tooth/
restoration interface using scanning electron microscope.
As for the clinical study, twenty patients received forty class I restorations in primary molars using split- mouth design. Clinical
performance was evaluated using US Public Health Service modified Ryge
criteria. Restorations of both materials were evaluated for: anatomic form,
marginal integrity, marginal discoloration, surface texture and recurrent
caries. Evaluations were done after 1 week, 3 months, 6 months, 9 months,
as well as, after 12 months.
As for the in- vitro study, a total of thirty extracted, caries-free,
premolars were prepared with a standardized cavity preparations, fifteen of
which were restored with the self- adhering flowable composite (group A)
and the other fifteen teeth were restored with the conventional flowable
composite with its corresponding, one- step adhesive system (group B).
Each group was, furtherly, subdivided into T1, T2 and T3 for three storage
periods of 1 week, 1month and 3 months respectively.
