Summary: | Introduction: Adhesive dentistry is overwhelmingly evolving
with respect to the dental surgeon’s and patient’s perspective.
Embracing the concept of minimally invasive dentistry which
follows minimum intervention performed to produce good
adhesion and tooth coloured restoration, in turn makes the newer
generation bonding agents more acceptable and appropriate
withstanding the demand for stable restoration.
Aim: To study and compare the extent of microleakage between
tooth and restoration interface in class V composite resin
restorations applying one Total Etch (AdperTM single bond), two
Self Etch (AdperTM SE Plus, AdperTM Easy One) and Universal
bonding agents using dye penetration method.
Materials and Methods: A total of 120 freshly orthodontically
extracted human maxillary and mandibular premolars were
included in the study. Class V cavities were prepared with a
cylindrical diamond bur on the facial surface of each tooth,
having approximate dimensions of 3 mm × 2.5 mm × 1.5 mm.
Teeth were divided into four groups (30 in each group). Group A
AdperTM single bond 2 (3M ESPE), Group B AdperTM SE Plus (3M
ESPE), Group C AdperTM Easy One (3M ESPE), Group D AdperTM
Single Bond Universal (3M ESPE) bonding agents were applied
as per the manufacturer’s instructions and the cavities were
then restored with nanohybrid composite resin (Tetric N Ceram
Ivoclar Vivadent). Teeth were then thermocycled for 200 cycles
at 5°-55°C with 60 seconds of dwell time. Specimens were
subjected to a dye leakage test. Microleakage was evaluated
using a stereomicroscope. Data was analysed using KruskalWallis, Dunn and Mann-Whitney test to assess the difference in
microleakage among various adhesives.
Results: The present study revealed that the microleakage was
more at the gingival margin when compared with occlusal and
this was found to be statistically significant. At the occlusal
margin statistical significant difference was found only between
AdperTM Easy one and AdperTM SE Plus, on the other hand at
gingival margin no statistical significant difference was found.
Conclusion: One step self etch agents showed less microleakage
than total etches and universal adhesive at occlusal margin.
Higher degree of microleakage was observed at gingival margin
compared to occlusal margin. |
