Brief Summary

There is a deficiency in literature which compares the blending effect and color matching of translucent shade bulk-fill resin composite with shaded bulk-fill resin composite. So in this research color matching and blending effect will be instrumentally measured the by a spectrophotometer. A visual assessment also will be done in-vivo and ex-vivo.

Conditions

Tooth Decay

Outcome Measures

Primary Outcomes (1)

• In-vivo visual color matching and blending effect by visual Score from 1 to 5

  Visual score from 1-5. The rank (1) is for mismatch or totally unaccepted, (2) is for poor match or hardly accepted, (3) is for good match or accepted, (4) is for close match or small difference, (5) is for exact match or no color difference

Study Arms (2)

Translucent bulk-fill resin composite

ACTIVE COMPARATOR

\*Shaded bulk-fill resin composite. Bulk-fill resin composite which has no shade and could match any other shade. It will be compared for shade accuracy to the haded bulk-fill resin composite.

Other: Shaded bulk-fill resin composite

Shaded bulk-fill resin composite

EXPERIMENTAL

\*Translucent bulk-fill resin composite Bulk-fill resin composite which has a specific shade and should only be filled in teeth with the corresponding shade

Other: Shaded bulk-fill resin composite

Interventions

Shaded bulk-fill resin composite OTHER

Dental bulk-fill resin composite with shades A1, A2, A3

Shaded bulk-fill resin composite; Translucent bulk-fill resin composite

Eligibility Criteria

• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

• People with simple class I posterior teeth would be selected without any preference of age or gender.
• Selected molars should only shaded A2, and A3 as these are shades under investigation.
• Patients with multiple caries teeth are preferred.
• Patients should be medically free and with good health.
• Selected molars should be vital.
• Patients should accept participation in the study.

You may not qualify if:

• Very deep carious molars that are indicated for root canal treatment or pulp capping.
• Teeth which are cracked, badly decayed crowns, non-restorable, periodontally affected, non-vital or abscessed.
• Patients who refuse to accept participation or had psychological disturbance will be excluded.
