Evaluation of Two Different Methods of Resin Composite Application In Class II Restorations

Evaluation of Two Different Methods of Resin Composite Application Using Bulk-fill Technique In Class II Restorations

Three clinical groups will be evaluated. Each group of patients will undergo one method of Resin Composite application (multi-layer technique 'control group' - bulk-fill Technique - Sonicfill technique). The restored teeth will be followed-up till one year. A comparison is going to be made between the three groups in relation to the modified United Sates Public Health Service (USPHS) criteria of good restorations.

The modified USPHS criteria include the evaluation of seven characteristics of the restorations: color match, marginal integrity, surface texture, wear of both restoration and antagonist, recurrent dental caries, fracture or detachment, and gingivitis around the abutment.

Inclusion Criteria:

1. Cooperated patients.
2. Good general health.
3. Good oral hygiene.
4. Aged 15 to 60 years.
5. Class II restoration (upper or lower)
6. Full erupted teeth.
7. Caries value D3 -D4 according to Daignodent.

Exclusion Criteria:

1. If the caries value according to Daignodent is less than D3 -D4.
2. If the tooth is partially erupted.
3. Class II box-like cavity only without any extensions.
4. Patient outside the required age range (15-60 years).
5. Bad oral hygiene.
