Genetically Transmitted Diseases in Pediatric Dentistry

Genetically transmitted diseases play a vital role in pediatric dentistry by influencing craniofacial growth, tooth development, and oral health. Genetics, the study of heredity, explains how traits and disorders are passed through genes located on DNA. Mutations or chromosomal abnormalities can result in single-gene, chromosomal, or multifactorial disorders, often affecting oral tissues. Conditions such as amelogenesis imperfecta, dentinogenesis imperfecta, and dentin dysplasia lead to defects in enamel and dentin, causing discoloration, fragility, and early tooth loss. Syndromes like cleft lip and palate, Gardner syndrome, and ectodermal dysplasia present with significant dental and craniofacial anomalies. Genetic factors also influence common conditions like caries, periodontal diseases, and malocclusion.Systemic disorders including bone, blood, metabolic, and immunologic diseases often manifest in the oral cavity, requiring careful dental management. Early diagnosis, preventive care, and multidisciplinary treatment are essential. Genetic screening and counseling further aid in risk assessment and timely intervention, improving outcomes in pediatric patients.
