The book "Skeletal Maturity Indicators" offers a comprehensive analysis of the biological and histological aspects of human skeletal growth and development. It highlights the morphogenetic and histogenetic changes that occur during the growth process and examines how genetic factors and environmental conditions influence physiological maturation. The work is particularly aimed at professionals in the field of orthodontics and provides valuable insights into the various biological indicators used to assess the growth status of children. These indicators include chronological age, dental development, body size, weight, and sexual maturation. The goal of the book is to systematically collect, analyze, and present the existing literature on skeletal maturity indicators in a concise manner to assist professionals in diagnosis, treatment planning, and the stability of orthodontic cases.
