Clinical Trial Summary

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.


Clinical Trial Description

This study will be conducted on 64 teeth selected from patients according to inclusion and exclusion criteria. They will be selected from the dental clinic in faculty of dental medicine, Al-Azhar University. The procedure will be explained and written informed consent will be obtained from each patient. The possible discomforts, risks, and benefits will be fully explained to the patients. Ethical committee approval will be obtained. Protocol of caries removal will be removed Subsequently, the central cariogenic biomasses and superficial part of the necrotic and demineralized dentin will be then excavated, leaving the last carious affected dentin layer. Sample grouping: The patients will be randomly assigned into four main groups according to the material used (16 for each) then each group will be subdivided into two subgroups (n=8) according to time of treatment (B1) after one month,(B2) after three month. A1: cavities will be treated by propolis extract then sealed directly by temporary conventional glass ionomer. A2: cavities will be treated by hesperidin then sealed directly by temporary conventional glass ionomer. A3: cavities will be treated with Silver diamine fluoride then sealed directly by temporary conventional glass ionomer. A4: cavities will be sealed directly by temporary restorative material (conventional glass ionomer) without any treatment. Evaluation of the microbiological effect Dentine samples will be collected from the base of the cavity using sterile spoon excavator from the four groups for baseline bacteriological assessment immediately after excavation, then another sample will be taken after one month for each subgroup (B1)and three months of treatment for each subgroup (B2). Evaluation of the remineralization effect Each group will be assessed radiographically immediately at base line (B0), after one month (B1) and three months (B2) to evaluate the dentin remineralization. ;
