Clinical Trial Summary

This case series study aims to evaluate the local effects of Atorvastatin (which belongs to the family of lipid-lowering drugs, known as statins) combined with β-TCP (which is a synthetic osteoconductive bone graft), on the volume of the residual bone defects and on hastening the bone regeneration after radicular jaw cyst enucleation using CBCT-based volumetric analysis to calculate the shrinkage rate of these defects.


Clinical Trial Description

Statement of the problem: According to the literature, the residual bone defects after medium-large-sized jaw cyst enucleation pose the risk for infection, insufficient healing, and pathological fracture. the gold standard of bone grafting materials remains the autologous bone graft, yet it is accompanied by risks including second surgery, the morbidity of the donor site, excessive bleeding, etc. Therefore, there is a constant search for alternative bone grafting materials, this is where the addition of atorvastatin to an osteoconductive synthetic bone grafting material (β-TCP) comes in. β-TCP takes anywhere from 6 to 18 months for complete resorption and replacement by bone, according to the literature. The addition of an osteoinductive material to an osteoconductive grafting material like β-TCP holds two premises; increasing the resorption of the β-TCP particles at the expense of bone deposition, and therefore leads to hastening the bone generation of the residual bone defects. Rationale: Studies have shown that the local application of lipid-lowering drugs, statins, induces bone growth by stimulating BMP-2. therefore, the addition of these pharmacological agents to osteoconductive bone graft materials, which lack osteogenic properties, could be a promising approach for bone regeneration. However, there is still no consensus in the literature on the optimal therapeutic dose and mode of application for statins. Furthermore, limited studies are available in the literature regarding the use of statins especially Atorvastatin as a biological modifier in filling bone defects after cyst enucleation. Therefore, the purpose of this study is to validate and evaluate the osteoinductivity of statins+ β-TCP combination using the Gouda et al., methodology used in maxillary sinus lifting using simvastatin but instead using atorvastatin in filling the residual defects of medium-large odontogenic radicular cysts (1.5 - 4 cm), which shows the suppressive influence on bone formation, as well as a greater risk for pathological fracture, infection, and insufficient bone healing. Methodology: The ratio of atorvastatin to β-TCP will be 0.1 mg: 14 mg, which was the methodology adopted by Gouda et al, based on the methodology of Nyan et al. ;
