Clinical Trial Summary

Aim of this study will be conducted to compare the shade matching and clinical performance of shade blocker versus chameleon effect of two single-shade of universal resin composite in class IV restorations over 1 year evaluation period

Description:

The color matching of both groups will be evaluated visually using modified USPH criteria

Eligibility

Inclusion Criteria:

moderate class IV defect with no lingual wall presence of favorable occlusion and teeth are in normal contact with the adjacent teeth good oral hygiene cooperative patients -

Exclusion Criteria:

• tooth hypersensitivity severe periodontal affection non vital teeth heavy smoking

Intervention

Diagnostic Test:
• single-shade universal resin composite (omnichroma) with blocker( omnichroma blocker)
(OMNICHROMA BLOCKER) is indicated for preventing shade-matching interference in Class IV restorations, Masking dark dentition and dentin. In cases where there is a lack of tooth structure to bond to, (BLOCKER) works as a supplementary product to provide a lingual wall to the restoration, prevent shade-match obstruction and mask staining.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	shade matching	the shade matching of both groups will be assessed visually by using modified USPH criteria.; score: 1- Alpha : the restoration match the shade and translucency of the adjacent tooth 2-Bravo : there is a mismatch in the shade and translucency but it is within a normal range of tooth shade 3- Charlie: the mismatch is beyond the normal range of the tooth shade and translucency	12 months
