Detaillierte Beschreibung
Examination and selection of patients will be done according to the inclusion and exclusion criteria. A class V cavity will be prepared after local anesthesia has been given. Followed by the placement of the restorative material according to the randomization sequence.
For the intervention: the primer will be applied first followed by filling of the cavity using self cure composite (Stella Automix or Stela Capsule, SDI Ltd, Australia). For the control group: etching of the cavity (Kulzer Gluma Etch, Kulzer GmbH, Germany) will be done followed by rinsing, drying, applying the bonding agent (Solobond M, Voco GmbH, Germany), curing, and lastly, applying the highly filled flowable composite (Polofil NHT flow, Voco Gmbh, Germany) and curing.

Beschreibung
Patient-related Criteria:
A) Inclusion Criteria:
- Patients consulting in the outpatient clinic with cervical carious lesion.
- Age between 21-45 years.
- Males and females.
B) Exclusion Criteria:
- Systemic disease or severe medical complication.
- Allergy to any of the restorative materials.
- Pregnancy.
- Disabilities.
- Heavy smoking; xerostomia.
- Lack of compliance.
- Evidence of severe bruxism, clenching, or temporomandibular joint disorders or bizarre habits.
Tooth-related Criteria:
A) Inclusion Criteria:
- Small to moderate class V carious lesion.
- Teeth are vital with no signs of irreversible pulpitis.
- Caries cervical margins above the CEJ.
- Well-formed and fully erupted in normal functional occlusion with natural antagonist.
B) Exclusion Criteria:
- Deciduous teeth; as the study is targeting only permanent teeth.
- Deep carious defects (close to the pulp, less than 1 mm distance).
- Tooth hypersensitivity.
- Teeth with previous restorations, which may add another variable to the study (type of old restorative material, extent of recurrent caries).
- Heavy occlusion and occlusal contacts or history of bruxism.
- Endodontically treated teeth.
- Periapical pathology or signs of pulpal pathology.

Intervention / Behandlung |
|---|---|
|
Experimental: Self-cure Bulk Fill Resin Composite (Stela Automix or Stela Capsule, SDI Limited, Australia)
|
A class V cavity with 1 mm occlusal bevel will be prepared after administrating local anesthesia followed by rubber dam isolation.
Stela Primer (SDI Limited, Australia.)
will be applied for 5 seconds on the cavity and the margins, then it will be gently dried with air for 2-3 seconds without light curing.
The self-cure bulk fill resin composite (Stela Automix or Stela Capsule, SDI Limited, Australia) will be applied then sculpted using a gold-plated composite applicator (Lascod, Italy).
Full polymerization will take place after 4 minutes.

|
Aktiver Komparator: Highly Filled Flowable Composite (Polofil NHT flow, Voco GmbH, Germany)
|
A class V cavity with 1 mm occlusal bevel will be prepared after administering local anesthesia.
Rubber dam isolation will be done, , etching of the enamel (20-30 seconds) and dentin (15 seconds) using a 35% phosphoric acid etch (Kulzer Gluma Etch, Kulzer GmbH, Germany), then rinsing for 20 seconds followed by controlled drying of the cavity till it's slightly moist.
Application of the bonding agent (Solobond M, Voco GmbH, Germany) using a disposable brush and leaving it to act for 30 seconds then an air jet will be used to disperse the bonding agent.
Curing for 20 seconds will be done using a LED light curing unit with curing intensity 1200-3000 mw/cm2 (CuringPen-E, Changzhou Sifary Medical Technology Co., Ltd, China).
Flowable composite (Polofil NHT flow, Voco GmbH, Germany) will be placed, adapted by gold plated applicator then light polymerized for 20 seconds using light emitting diode (LED) light curing unit.

Marginal Adaptation
Zeitfenster: 18 months
|
The restoration will be clinically assessed according to the modified USPHS criteria.
It will be give an Alpha score when the restoration is closely adapted with no detectable margin.
It will be given a Bravo score when there is a detectable marginal discrepancy, but it still clinically acceptable.

|
Marginal Discoloration
Zeitfenster: 18 months
|
