Clinical Evaluation of High Viscosity Glass Ionomer Strip Crowns in Primary Maxillary Incisors

April 28, 2023 updated by: Beste Ozgur, Hacettepe University

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Following the decision on the appropriate size of celluloid strip crown, the tooth will be isolated using roll cottons and the "cavity conditioner" (GC, Japan) will be applied to all surfaces for 10 seconds, washed away and dried with cotton pellets. The selected celluloid strip crown will be filled with a fluoride-releasing bulk fill hybrid glass ionomer cement (EQUIA Forte, GC, Japan) prepared by mixing for 10 seconds in an automatic mixer and placed on the tooth with light pressure. The excess material on the crown margins will be removed with a hand instrument, and the celluloid strip crown will be removed from the tooth. If necessary, the restoration will be polished using a polishing discs. After the crown surface is washed and dried, a nano-filled surface sealant (EQUIA Forte Coat, GC, Tokyo, Japan) will be applied for 10 seconds with a micro-tipped applicator and light cured for 20 seconds. Clinical evaluations will be done at the 3rd, 6th and 12th months.

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.

Experimental: Strip Crown
This is a single-arm study. High viscosity glass ionomer strip crowns will be performed to all patients.
Other: Pediatric Strip Crown and High Viscosity Glass Ionomer Cement

Primary Outcome Measures

Primary Outcome Measures
