Abstract
Purpose/aim: To evaluate in a randomized controlled study
the 5-year clinical durability of a flowable resin composite
bulk-fill technique in Class I and Class II restorations.
Materials and methods: 38 pairs Class I and 62 pairs Class
II restorations were placed in 44 male and 42 female (mean
age 52.4 years). Each patient received at least two, as similar
as possible, extended Class I or Class II restorations.
In all cavities, a 1-step self-etch adhesive (Xeno V+) was
applied. Randomized, one of the cavities of each pair received
the flowable bulk-filled resin composite (SDR), in increments
up to 4mm as needed to fill the cavity 2mm short of the
occlusal cavosurface. The occlusal part was completed with
the nano-hybrid resin composite (Ceram X mono+). In the
other cavity, the resin composite-only (Ceram X mono+) was
placed in 2mm increments. The restorations were evaluated
using slightly modified USPHS criteria at baseline and then
yearly during 5 years. Caries risk and bruxing habits of the
participants were estimated.
Results: No post-operative sensitivity was reported. At
5-year 183, 68 Class I and 115 Class II, restorations were evaluated.
Ten restorations failed (5.5%), all Class II, 4 SDR-CeramX
mono+ and 6 CeramXmono+-only restorations. The main reasons
for failurewere tooth fracture (6) and secondary caries (4).
The annual failure rate (AFR) for all restorations (Class I and II)
was for the bulk-filled-1.1% and for the resin composite-only
restorations 1.3%. For the Class II restorations, the AFR was
1.4% and 2.1%, respectively.
Conclusions: The stress decreasing flowable bulk-fill resin
composite technique showed good durability during the 5-
year follow-up.
