There is a peculiarity in the articulation of the two parietal bones with the frontal bone at the top of the skull. The anterior border of the parietal bone is deeply serrated and is bevelled at the expense of the outer surface above and of the inner below. The border of the vertical portion of the frontal bone is thick, strongly serrated, bevelled at the expense of the internal table above, wh...

Bone formation and skeletal repair are dynamic processes involving a fine-tuned balance between osteoblast proliferation and differentiation orchestrated by multiple signaling pathways. Canonical Wnt (cWnt) signaling is known to playing a key role in these processes. In the current study, using a transgenic mouse model with targeted disruption of axin2, a negative regulator of cWnt signaling, w...

This research evaluated the bone repair process after implantation of homogenous demineralized dentin matrix (HDDM) in surgical defects in the parietal bone of rabbits with alloxan-induced diabetes, using a polytetrafluorethylene (PTFe) barrier for guided bone regeneration. Thirty-six rabbits were used and divided into four groups: control (C, n = 12), diabetic (D, n = 12, left parietal bone), ...

The aim of the study was to evaluate the possibility to obtain guided bone regeneration with two types of physical barriers (calcium sulfate and PTFE nonporous barrier) in surgical defects created in rat parietal bones. In the right parietal bone the calcium sulfate barrier filled out the whole defect and in the left parietal bone the barrier of PTFE was positioned in the floor and externally t...

A single isolated parietal bone from the Fort Sill deposit of Oklahoma is described. It has a well-developed upper temporal opening, resembling that of the primitive South African diapsids. The parietal is compared with that of Araeoscelis and Youngopsis. Based on comparison with this parietal and the configuration of the rear skull table of millerosaurs and romeriids, the bone usually identifi...

background and aims. autogenous bone graft is commonly used for reconstruction of bone defects in routine surgical procedures. the complexity of producing bone grafts and their application has lead to the use of human bone matrix gelatin (hbmg). the present study was conducted to compare the efficacy of hbmg and autograft on the reconstruction of bone defects in rats. materials and methods. in ...

Benign skull lesions are routinely encountered in clinical practice. The aim of this review is to describe the Computed tomography (CT) findings of solitary benign parietal lesions. Benign parietal bone lesions can exist in patients with history of cancer. Metastasis to the calvarium is rare compared to other sites in the body and primary skull tumors are even rarer. This is the second report o...
