Filter by:The aim of this clinical study is to investigate the clinical performance of a calcium silicate used in the treatment of deep caries lesions. Individuals participating in the research will be selected from patients with at least one deep dentin caries (D3) who apply to the Restorative Dentistry Clinic of Hacettepe University Faculty of Dentistry. The age range will be range 18-45. The teeth to be restored will be evaluated clinically and radiographically. A rubber dam will be used during the treatment. After the removal of enamel, carious tissue at the lateral walls of cavities will be removed to hard dentin using round and single-use round steel burs operating at low speed in all groups. A reasonable amount of soft carious tissue will be left over the pulp. In test (Calcium silicate) and control(calcium hydroxide) groups, after caries removal, respective material will be applied on the pulpal floor. Then, materials will be sealed by resin-modified glass ionomer cement and permanent restoration will be performed. Evaluation will be conducted after 6, 12, and 18 months.
Atraumatic Restorative Treatment (ART) was proposed as a new and effective method in the 1990s to provide conservative dental treatment to the people living in economically underdeveloped countries, due to lack of dental treatment facilities. In the technique, after the carious dentin is removed by excavation with hand instruments, the powder-liquid system conventional glass ionomer cement (GIC) which does not require special devices for mixing and hardening is used as a filling material. Because of these advantages of the treatment, the usage fields of ART have been expanded considering that it can be applied in the cases that working with rotary instruments is difficult or even impossible. But only a few research has been conducted on ART in adults and it must be investigated in terms of the clinical safety of ART by the studies focused on the counts and activities of the microorganisms in carious dentin left on the cavity floor. The purpose of this study is to investigate the reliability of ART in adult individuals related to the marginal adaptation of the restorations and the microbiological changes in the left carious dentin using in vitro and in vivo methods. In the in vivo part of the study, occlusal dentin carious of 25 participants at high risk of caries were removed with hand instruments and microorganisms of the last removed carious dentin were evaluated quantitatively concerning the bacterias playing a major role in caries lesions. The restorations of the teeth were carried out using ART technique with a GIC which has been proven its effectiveness in preventing the caries progression and recurrent caries in the practice of dentistry for many years. After six months, the microbiological assessment was repeated such as baseline. Marginal adaptation and the presence of the gaps in the ART restorations on the replicas created with the impression materials at the baseline and sixth month were investigated under scanning electron microscope. At the end of the study, the teeth were restored by the conventional methods and using composite material.
The present study will be performed to evaluate: 1. The remineralizing effect of natural materials versus synthetic materials on deep carious dentin after selective caries removal. 2. The antibacterial effect of natural materials versus synthetic materials on deep carious dentin.
