A Review on Dental Age Estimation in Children and Adolescents

Abstract

Children are seen as beings who exist from birth through puberty, while teenagers are regarded as existing from puberty until around the age of 20 years. For a number of legal processes, including child labor, employment, the age of majority, rape, adoption, marriage eligibility, and situations where the birth certificate is unavailable, age estimation in children and adolescents is crucial. Despite the wide range of methods available, dental age estimation techniques that take into account tooth maturation are thought to be the most reliable predictors of chronological age in subadults. This is because genetic factors predominate and environmental factors, particularly between birth and age ten, tend to have little impact on tooth maturation. The eruption of teeth holds greater significance in the deciduous dentition, where genetic factors predominantly govern the process, compared to the permanent dentition. Conversely, tooth calcification serves as a viable indicator for estimating dental age in both primary and permanent dentitions. Current dental age estimation methods are based on age-related changes in teeth, such as tooth growth and development, changes that occur after teeth form, and biochemical changes. Therefore, in this review article, we will explore the several methodologies used for dental age assessment in children and adolescents.
