Clinical Study

Histologic and Histomorphometric Comparison between Sintered Nanohydroxyapatite and Anorganic Bovine Xenograft in Maxillary Sinus Grafting: A Split-Mouth Randomized Controlled Clinical Trial

Figure 5

The bone around both biomaterials was characterized by the presence of osteocytes () embedded inside the mineralized bone matrix. In the test group, osteocytes were generally more numerous near the material surface. NHA: sintered nanohydroxyapatite; ABB: anorganic bovine bone; VB: vital bone; MS: marrow spaces (Toluidine Blue and Azure II; original magnification: 400x).
