Bovine and Ovine Teeth as a Substitute for the Human Teeth: An Experimental Study.

Statement Of The Problem: Although various kinds of research have been conducted to compare the physical and chemical properties of dentin and enamel in animal and human samples, proving the ability of animal dentin material as a good substitute for human specimens is always a challenge for experimental studies.

Purpose: The aim of the present study is to investigate whether the changes in the dentin microhardness of animal samples are similar to those of human samples or not.

Materials And Method: In this study, sixty single-rooted human, bovine, and ovine teeth (n=20 in each group) were decoronated at CEJ.

Microfluidic platforms in diagnostic of ovarian cancer.

The most important reason for death from ovarian cancer is the late diagnosis of this disease. The standard treatment of ovarian cancer includes surgery and chemotherapy based on platinum, which is associated with side effects for the body. Due to the nonspecific nature of clinical symptoms, developing a platform for early detection of this disease is needed.
