The Clinical Performance of Two Dentine Replacement Materials in Deep Occlusal Cavities (Randomized)

April 5, 2025 updated by: Dalia Sameh Fawzi

The Clinical Performance of Two Dentine Replacement Materials in Deep Occlusal Cavities: A Randomized Clinical Trial

Higher mechanical properties are needed to restore structurally compromised posterior teeth, short fiber reinforced resin composite and injectable bioactive resin composites provide superior properties to flowable composites that were traditionally used to improve adaptation in deep cavities below the packable resin composite restorations. Thus, this study was designed to assess the clinical outcome of high strength dentine substitute materials.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Fracture
Time Frame: T1: 1 week T2: 6months T3: 12 months
  1. Clinically excellent/very good (sufficient): Restoration is completely present without deficiencies detectable after air drying.
  2. Clinically good (sufficient): Restoration is completely present with minor deficiencies detectable after air drying
  3. Clinically satisfactory (sufficient): Restoration is present with deficiencies detectable without air drying
  4. Clinically unsatisfactory (partially insufficient): Localized but severe deficiencies regarding fracture and retention
  5. Clinically poor (entirely insufficient): Generalized severe deficiencies
T1: 1 week T2: 6months T3: 12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Recurrent caries
Time Frame: T1: 1 week T2: 6months T3: 12 months
  1. Clinically excellent/very good (sufficient): No caries/demineralization at the restoration margin detectable after air drying.
  2. Clinically good (sufficient): First visible signs of a non-cavitated caries lesion at the restoration margin detectable after air drying.
  3. Clinically satisfactory (sufficient): Established, non- cavitated caries lesion or microcavity at the restoration margin detectable without air drying.
  4. Clinically unsatisfactory (partially insufficient):

    Localized dentin cavity at the restoration margin.

  5. Clinically poor (entirely insufficient): Extensive dentin cavity at the restoration margin.
T1: 1 week T2: 6months T3: 12 months
Post operative sensitivity
Time Frame: T1: 1 week T2: 6months T3: 12 months
  1. Clinically excellent/very good (sufficient): No Postoperative hypersensitivity.
  2. Clinically good (sufficient): Minor postoperative hypersensitivity.
  3. Clinically satisfactory (sufficient) Distinct "moderate" postoperative hypersensitivity.
  4. Clinically unsatisfactory (partially insufficient): Severe "persistent" postoperative hypersensitivity.
  5. Clinically poor (entirely insufficient): Extreme postoperative hypersensitivity "Irreversible pulpitis".
T1: 1 week T2: 6months T3: 12 months
