Clinical Evaluation Of Class I Composite Resin Restorations Using Three Different Adhesive Systems

October 9, 2020 updated by: Nazire Nurdan Çakır, Nuh Naci Yazgan University

Erciyes University Clinical Research Ethics Committee

Nowadays, most composite resins require the use of an adhesive material prior to application. For this purpose, etch & rinse (ER) and self-etch (SE) systems have been used for many years. While many in-vitro studies have been conducted in the literature comparing three adhesive systems, the number of clinical studies is less and inadequate. Therefore, the aim of this study was to investigate the effect of 3 different adhesive systems commonly used in clinics on the success of class I composite restorations using the criteria of the World Dental Federation (FDI) and the United States Public Health Service (USPHS).

Detailed Description

Nowadays, most composite resins require the use of an adhesive material prior to application. For this purpose, etch & rinse (ER) and self-etch (SE) systems have been used for many years. Compared to SE systems, which are simplified and very easy to use, requiring less technical precision, traditional ER systems are still very popular and preferred by dentists. However, current researchers indicate that ER systems are more effective on enamel than dentin and that this effect is better than SE systems. SE systems are approaches in which the acid application and washing step are eliminated clinically and the possibility of making mistakes during the application and manipulation is reduced. An important advantage of these systems is that demineralization and resin infiltration occurs at the same time. Clinically, the application times are shorter than traditional systems. Two-steps SE systems have been used for a long time. In this system, the need for a separate acidic primer application has needed clinicians reason to search for single-steps bonding agents. And, in recent years, single-step SE systems also called "all in one", have been developed that include all steps of pickling, primer application, and adhesive agent application. However, there are studies showing that these systems do not perform as well as two-step SE systems. While many in-vitro studies have been conducted in the literature comparing three adhesive systems, the number of clinical studies is less and inadequate. Therefore, the aim of this study was to investigate the effect of 3 different adhesive systems commonly used in clinics on the success of class I composite restorations using the criteria of the World Dental Federation (FDI) and the United States Public Health Service (USPHS).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Active Comparator: Single Bond 2
Single Bond 2 is a traditional etch and rinse adhesive system. It is used to bond the composite resin to the dental tissues. It was applied to the cavities opened in accordance with the manufacturer's instructions.
Other: Dental adhesive materials.
It is used to bond the composite resin to the dental tissues. That is, it is used to bond dental filling materials to dental tissues.
Active Comparator: Clearfil SE Bond
Clearfil SE bond is traditional two step self-etch adhesive system. It is used to bond the composite resin to the dental tissues. It was applied to the cavities opened in accordance with the manufacturer's instructions.
Other: Dental adhesive materials.
It is used to bond the composite resin to the dental tissues. That is, it is used to bond dental filling materials to dental tissues.
