Developmental anomalies in oral and maxillofacial tissues are congenital conditions affecting the growth, structure, or function of the mouth, jaws, and related tissues. These anomalies include cleft lip and palate, micrognathia, macrogenia, and dental abnormalities like hypodontia or supernumerary teeth. They may result from genetic mutations, environmental factors, or prenatal influences. Early diagnosis and appropriate management are crucial for functional and aesthetic outcomes.
