Sealing Ability of Different Root Canal Sealers and Obturation Techniques

Aim:The objective of this study was to assess radiographically the dimensional and volumetric changes of the grafting material after sinus lifting procedures and delayed implants placement.Subjects and methods: 14 patients underwent lateral sinus lifting, followed by delayed implant placement at six month after grafting.Dimensional changes were measured in the form of height involving the residual ridge and the allogenic graft immediate post-operative, at 6th month and at 12 month.Volumetric analysis of the grafting material was conducted at the following three intervals immediate after grafting, at 6 month, and 12 month postoperative.Results: Vit D showed significant improvement between goup A (29.245.03)and group B (12.772.06)and P-Value was >0.05, while calcium levels showed no statistical difference.Radiographically, no statistical difference in bone volume and height in both groups.Conclusion: Improvement of the vitamin D deficiency by vit D and Ca supplements not had any significant changes on the dimensional and volumetric measurements of the grafted area at the end of the study.
