简要总结
The objectives of this study are to evaluate and compare the biofilm inhibition and re-mineralizing potential at tooth restoration interface and their 2-year clinical performance in class I cavities.The patients will be selected from the Outpatient clinic at Faculty of Dentistry, Mansoura University. Patients will be informed about the steps of the study, whom will approve, will sign a written consent form. The form and protocol will be approved by the Ethics Committee. Each patient should have 4 frank carious dentinal lesions (ICDAS score 4 or 5) in posterior teeth. A periapical radiograph will be performed to evaluate the extension of the carious lesion and to ensure that there is no radiolucency in the periapical or furcation area. The teeth have to be vital, not sensitive to percussion and/or spontaneous pain. The patients will be required to have complete and normal occlusion as well as good oral hygiene.
详细描述
This study will be intended to evaluate and compare the biofilm inhibition and re-mineralizing potential at tooth restoration interface and their 2-year clinical performance in class I cavities.
Null hypothesis This study will be designed to test the null hypothesis that there will be no significant difference in neither biofilm inhibition nor remineralizing potential at tooth-restoration interface of the used tested materials. Also, that there will be no significant difference in the 2-year clinical outcomes of the bioactive restorative materials in class I cavities.
Sample size calculation was based on clinical performance according to FDI criteria between different bioactive restorative materials that was retrieved from previous research.19 Using G power program version 3.1.9.7 to calculate sample size, using 2-tailed test, α error =0.05 and power = 80%, the total calculated sample size will be 30 cases at least in each group Patient selection The patients will be selected from the Outpatient clinic at Faculty of Dentistry, Mansoura University. Patients will be informed about the steps of the study, whom will approve, will sign a written consent form. The form and protocol will be approved by the Ethics Committee. Each patient should have 4 frank carious dentinal lesions (ICDAS score 4 or 5) in posterior teeth. A periapical radiograph will be performed to evaluate the extension of the carious lesion and to ensure that there is no radiolucency in the periapical or furcation area. The teeth have to be vital, not sensitive to percussion and/or spontaneous pain. The patients will be required to have complete and normal occlusion as well as good oral hygiene.
Study Design:
The total number of patients will be 30 patients. Each patient will receive restorative materials studied in this investigation.

研究组 & 干预措施
application of beautiful blukfill II shofu composite
Operative procedures were performed under local anesthesia and rubber dam isolation. Cavities were prepared using round diamond points (for enamel) and straight fissure and round carbide burs (for cutting in dentin) in a high-speed handpiece . Cavities were prepared following common principles for moderate to large class I adhesive resin composite restorations.
cavities without a liner, beautiful blukfill II shofu composite were placed in bulk (a maximum 4mm thickness layer) with manual filling instruments and burnishers and cured for 40 seconds. Occlusal adjustments were performed using fine grit yellow-coded tapered with round ends and flame-shaped diamond stones (Komet, USA).
Polishing was done using rubber points and polishing brushes (Occlubrush, Kerr, Switzerland) operated at low-speed with water coolant and minimal pressure.

结局指标
主要结局
Postoperative hypersensitivity/pulp status
时间窗: Two years after restoration
Postoperative hypersensitivity/pulp status.The postoperative hypersensitivity/pulp status will be assessed based on the updated FDI criteria - Intensity was assessed with Visual Analogue Scale. Postoperative sensitivity was evaluated by blowing a stream of compressed air for 3 seconds at a distance of 2-3 cm from the restoration. -Vitality was tested with application of cold (dry ice) and compared the reaction with the adjacent vital teeth . This parameter is evaluated by scoring the pain experienced during chewing and/or with cold or warm food items, as reported by the patient. The criteria consist of five scores: scores 1-3 indicate success, score 4 indicates the need for restoration repair, and score 5 indicates the need for restoration replacement.
Marginal adaptation
时间窗: Two years after restoration]
The marginal adaptation will be evaluated through visual examination using a - A magnifying aid (loupe 4.5 x) was used for evaluation. Two special probes with different blunt tips (150 and 250 μm). This assessment will be conducted according to the updated FDI criteria. The criteria consist of five scores: scores 1- 3 indicate success, score 4 indicates the need for restoration repair, and score 5 indicates the need for restoration replacement.
