Intervention / Behandling
Detaljeret beskrivelse
A total of 188 premolar teeth with proximal cavity to be assigned on alternate basis in two groups. Intervention group teeth received Automatrix band after cavity preparation followed by the separation ring using clamp while the control group received Automatrix band alone.
All teeth to be restored with P-60 composite restorative material(3M-ESPE Dental, USA). Outcome (proximal tightness) is determined by a blinded assessor just after the restoration.

Eksperimentel: automatrix band, Separation ring
The prepared teeth received Automatrix band (similar to the control group, product code# 62422513).
The Automatrix was burnished against the adjacent tooth gently.
Anatomical wedges were applied in the proximal area and then the separation ring (BiTine® round ring by Palodent systems, Dentsply International, DE, USA product # 659040) placed with the help of retainer forceps.

Aktiv komparator: automatrix band
Teeth received Automatrix band alone (Wide-Regular type, dimensions 7.9 mm height and 0.05mm thickness, product code # 62422513).
It was secured on the prepared tooth and burnished against the adjacent tooth gently.
Anatomical wedges were placed in the inter-proximal area gingival to the cavity preparation.
