Adhesive Performance of Glass Ionomer and Resin Based Adhesive Systems: A 3 Years Prospective Clinical Evaluation

Study Overview
=================
Brief Summary
-----------------
This study aimed to clinically evaluate the 3-years clinical performance of glass ionomer and resin based adhesive systems in Class V restorations.

Detailed Description
-----------------
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?

Official Title
-----------------
Adhesive Performance of Glass Ionomer Versus Resin Based Adhesive Systems

Conditions
-----------------
Dental Leakage

Intervention / Treatment
-----------------
* Procedure: Etching with phosphoric acid gel (3M ESPE, St. Paul, MN, USA)
* Procedure: Self-etch adhesive (Kuraray, Tokyo, Japan)
* Procedure: Chemical bond adhesive (GC, Corporation, Tokyo, Japan)


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Patients with primary caries involving cervical surface only with ICDAS 2 and 3. Patients with normal and full occlusion.

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.
