Objectives
Contents The Histology course is divided in four sections: citology, histology and embryology and a special section is dedicated to the study of structure, organization and development of hard and soft tissues of the oral cavity.

Recommended Bibliography The main objective of the course is to provide the theoretical and practical concepts on the tissues structure and development with a focus on the hard and soft tissues of the oral cavity in order to facilitate the subsequent understanding of the pathological processes and the identification of consequent therapeutic measures.
