Brief Summary
Class II caries affects proximal surfaces of premolars and maintain their anatomical proximal contact of tooth, is important to avoid food impaction in the interdental area for protection of periodontium and occurrence of secondary carious lesion.Different types of Matrix band system are used to restore tooth cavities with missing proximal walls, including flat or pre-contoured bands, retainer-fixed circumferential systems, and sectional matrices, and either metal or plastic matrices which produces good contours and contacts for use with amalgam and can also be employed for insertion of composite resin.This study aimed at assessing the influence of different matricing techniques :either sectional matrix or circumferential matrix and the influence of operator experience on reproduction of optimum proximal contacts for posterior proximal resin composite restorations.

Outcome Measures
Primary Outcomes (1)
Tightness of proximal contact
Proximal contact either optimum, tight, or open contact by using dental floss
immediately after the procedure
Study Arms (2)
Sectional matrix band
EXPERIMENTALprecontoured sectional matrix band
Circumferential matrix band
ACTIVE COMPARATORCircumferential matrix band applied by tofflemire retainer
Interventions
The sectional matrix is the best way to achieve a strong contact point in Class II restorations with composite resin in the posterior dental sector. The pre-wedging is essential to get a separation between teeth which avoid the matrix deformation during its insertion
Circumferential matrix (thickness 0.038mm) ,the band encircle the tooth and secured by retainer on the buccal and lingual aspect
Eligibility Criteria
You may qualify if:
- Tooth with compound class 2 cavities Patient with good general health. Patient with minimum age of 18 years. Fully erupted occluding premolar and molar teeth.
You may not qualify if:
- Tooth complex class 2 cavities. Tooth with severe periodontal disease. Diastema between posterior teeth. Third molars are excluded.
- Tooth mobility greater than 1 mm.
