Clinical Performance of Glass-hybrid in the Treatment of Class III Restorations

Study Overview
=================
Brief Summary
-----------------
This is a double blinded, split mouth, randomized clinical study that evaluated the performance of a glass hybrid restorative material in class III lesions. The lesions will be restored with glass hybrid restorative (Equia Forte) or anterior composite resin (G-aenial Anterior). Restorations will be evaluated after 24 months according to FDI criteria and the data will be analyzed.

Detailed Description
-----------------
The aim of this study was to comparatively evaluate the clinical performance of a glass-hybrid-restorative with an anterior composite resin (G-aenial Anterior) in class III lesions. Participants who are 18 years of age or older and healthy, and who have applied to the Restorative Dentistry Department of Hacettepe University Faculty of Dentistry to receive treatment for class III lesions on their front teeth will be included in the study. After explaining the purpose and conditions of the study, they will be asked to sign an informed consent form. The gender, age, and tooth numbers of the participants to be treated will be recorded. 100 upper incisors of 50 patients will be treated, with attention paid to the balanced distribution of teeth in the right and left arches. The split-mouth model will be used in the study, with two teeth included in one mouth and each restorative material placed in one tooth. The restorative material to be placed on the teeth will be determined randomly. Before starting the restoration, papers with the names of both materials will be placed in envelopes, and then the assistant staff will be asked to randomly select one of the envelopes during the restoration stage to provide randomization.Data were will be analyzed with Chi- Square, Fisher's Exact Test, Mann U tests

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Equia forte HT (glass-hybrid) group<br>This study planned to investigate the clinical performance of Equia Forte HT (permanent glass hybrid restorative) in the treatment of anterior class III restorations. This arm of the study is the group whose effectiveness was investigated. The results will be evaluated by comparing with a traditional anterior resin composite in terms of functional, biological and aesthetic properties. | Procedure: Equia forte HT<br>* Restoration of anterior class III caries lesions<br>* Other names: G-Aenial anterior;|
| Active Comparator: G-Aenial anterior<br>This group will serve as a control. Equia forte HT (glass-hybrid) restorations will compare with the G-Aenial anterior anterior resin composite restorations. | Procedure: Equia forte HT<br>* Restoration of anterior class III caries lesions<br>* Other names: G-Aenial anterior;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Functional properties | The primary factor for determining the clinical performance of a restorative material is the Functional properties. Visual tactile examination tools will be used for evaluating restorations according to FDI criteria by two experienced researchers at 1- week 6-, 12-, 18- and 24- months. The functional properties are scored as 1- clinically excellent, 2-clinically good, 3-clinically sufficient/satisfactory, 4-clinically unsatisfactory 5-clinically poor (replacement necesessry). Clinically 1, 2 and 3 scores are clinical acceptable but 4 and 5 scores are designated as failure. | 2 years | 
| Esthetic properties | Second outcome is esthetic properties. The secondary factor for determining the clinical performance of a restorative material is the Esthetic properties. Visual examination will be used for evaluating restorations according to FDI criteria by two experienced researchers at 1- week 6-, 12-, 18- and 24- months. The Esthetic properties are scored as 1- clinically excellent, 2-clinically good, 3-clinically sufficient/satisfactory, 4-clinically unsatisfactory 5-clinically poor (replacement necesessry). Clinically 1, 2 and 3 scores are clinical acceptable but 4 and 5 scores are designated as failure. | 2 years |
