Risk factors for the development of dental agenesis

open access: yes, 2023
Introduction: dental agenesis is a disease characterized by the non-formation of some dental pieces, most frequently the lack of molars and upper lateral incisors. It affects not only the esthetics of people but also physiological processes such as feeding, so controlling the risk factors becomes a necessity. Objective: to describe the risk factors for
