Brief Summary
The aim of this study was evaluating the clinical effectiveness of the hand instrument in conjunction with sectional matrix when applying lateral forces at the contact area during curing to achieve large and tight proximal contacts in posterior teeth.

Outcome Measures
Primary Outcomes (1)
Contact tightness Device used: Dental floss Scoring unit US Public Health Service
Clinical Performance Proximal contact Modified USPHS Ryge criteria
Proximal contact tightness was measured after 6 months
Study Arms (2)
Control group 1
EXPERIMENTALTesting Palodent sectional matrix system only when placing Class II resin composite restorations is to increase proximal contact tightness.
Intervention group 2
ACTIVE COMPARATORA pre-contoured instrument called Optra contact (Ivoclar, Vivadent) will be used with group 2. For testing palodent matrix systems with Optracontact when placing Class II resin composite restorations is to increase proximal contact tightness with adjacent teeth when compared with group 1.
Interventions
innovative sectional matrix system with Nickel-Titanium rings, anatomically shaped matrix bands and adaptive self-guiding wedges that provides predictable, tight contacts and restorations that accurately replicate the natural tooth anatomy.
The instrument is used to achieve large and tight proximal contacts in posterior teeth.
