ORTIZ, S. M. A. & SALAZAR, M. L. OPG location in dental pulp of albino Swiss mice. Int. J. Odontostomat., 8(1):47-52, 2014.
ABSTRACT: Under physiological conditions, the dentinopulpar complex is not associated with remodeling and resorption. Osteoprotegerin (OPG) is a TNF molecule associated with osteoclast activation and differentiation. Therefore, OPG role in internal root resorption must be determined. We obtained histological sections of 5 μm in first molars from 8 hemimandibles of mice, which were subjected to the avidin-biotin peroxidase complex immunohistochemical procedure for detection of OPG. Differential OPG presence was identified in central and peripheral pulp in dental pulp of 4 and 12 week-old mice.
KEY WORDS: tooth, osteoprotegerin, resorption.
