A 12-month clinical evaluation of composite resins in class III restorations.

Purpose: This paired-tooth randomized controlled prospective clinical study compared the clinical performance of three composite resins in Class III cavities after 12 months.

Materials And Methods: Three materials were evaluated: a microfilled composite resin (Durafill VS), a hybrid composite resin (Filtek Z250), and a nanofilled composite resin (Filtek Supreme). Thirty-eight patients having at least three Class III restorations were enrolled in this study.

A six-month clinical study of a self-etching and an etch-and-rinse adhesive applied as recommended and after doubling the number of adhesive coats.

Purpose: In an intra-individual comparison, a 6-month randomized, controlled prospective study evaluated the clinical performance of a self-etching and an etch-and-rinse adhesive in noncarious cervical lesions applied as recommended and after doubling the number of adhesive coats.

Materials And Methods: Twenty-nine patients with at least two pairs of similar sized noncarious cervical lesions participated. One hundred sixteen restorations were placed and divided into the following groups: OS2: phosphoric acid + One Step Plus applied accordingto manufacturer's recommendation (2 coats of adhesive); OS4: phosphoric acid + One Step Plus (4 coats of adhesive); TY2: Tyrian SPE + One Step Plus applied according to manufacturer's recommendation (2 coats of adhesive); TY4: Tyrian SPE + One Step Plus (4 coats of adhesive).

Clinical evaluation of a nanofilled composite in posterior teeth: 12-month results.

This study compared the clinical performance of a nanofilled resin composite for posterior restorations with 2 microhybrid and 1 packable composite after 12 months of clinical service. Forty-two patients with at least 5 Class I or II restorations under occlusion were enrolled in this study. A total of 148 restorations were placed, 25% for each material (Filtek Supreme, Pyramid, Esthet-X or Tetric Ceram).

One-year clinical evaluation of a flowable resin liner associated with a microhybrid resin in noncarious cervical lesions.

The aim of this study was to compare the clinical performance over 1 year of a microhybrid composite resin for class V restorations both lined and not lined with a flowable composite resin. Nineteen patients having at least two pairs of cervical noncarious lesions under occlusion were enrolled in this study. A total of 38 restorations were placed, half for each group (Single-Bond + Filtek-Flow + Filtek Z250, and Single-Bond + Filtek Z250).
