About this study

The formulated null hypothesis was that there is no significant difference in the clinical performances between glass ionomer and resin based adhesive systems in Class V restorations for 3-years.

The research question was as follows: Do glass ionomer adhesives in class V restorations present better clinical performances than resin based adhesive systems according to the modified United States Public Health Service (modified-USPHS) criteria?

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients with primary caries involving cervical surface only with ICDAS 2 and 3.
  • Patients with normal and full occlusion.
  • Patients with tooth gives positive response to testing with an electric pulp tester.
  • Patients must have a good oral hygiene.
  • Patients with opposing teeth should be natural with no restorations.

Exclusion criteria

  • High caries risk patients with extremely poor oral hygiene.
  • Patients involved in orthodontic treatment or periodontal surgery.
  • Patients with periodontally involved teeth (chronic periodontitis).
  • Patients with heavy bruxism habits and clenching.
  • Patients with abutments should be excluded.

Treatment and study plan

Etching with phosphoric acid gel (3M ESPE, St. Paul, MN, USA)

Procedure

Etching enamel surface using phosphoric acid gel (3M ESPE, St. Paul, MN, USA)

Self-etch adhesive (Kuraray, Tokyo, Japan)

Procedure

No Etching enamel surface using phosphoric acid (self-etch technique) (Kuraray, Tokyo, Japan)

Chemical bond adhesive (GC, Corporation, Tokyo, Japan)

Procedure

Chemical bond with hydroxyapatite crystals of Enamel (GC, Corporation, Tokyo, Japan)

Primary outcomes

  1. Percentage % of patients with marginal staining

    Time frame: 3 years after restoration procedure

    Percentage of marginal staining in patients was clinically assessed using USPHS criteria. Restorations were given the score Alpha for the ideal clinical situation, Bravo for clinically acceptable and Charlie for clinically unacceptable and in need for replacement.
