Ask-Upmark Kidney Disease: Case Report of a Rare Congenital Malformation

Ask-Upmark kidney disease is a congenital renal malformation characterized by segmental hypoplasia, leading to progressive impairment of renal function and severe hypertension. It is a rare anomaly that presents with various complications. A 14-year-old boy diagnosed with Ask-Upmark kidney was referred for dental care. The patient presented with mouth breathing, unsatisfactory occlusion, and severe drug-induced gingival hyperplasia, which hindered speech, diet, and oral hygiene. Imaging revealed the presence of all permanent teeth, but with delayed eruption, oblique eruption pathways, and risk of impaction. Management included oral hygiene instructions, prophylaxis, and ulectomy to facilitate tooth eruption. This case highlights the oral manifestations associated with the management of Ask-Upmark kidney, specifically drug-induced gingival enlargement and eruption disturbances. It underscores the necessity of multidisciplinary treatment, including dentistry, to improve the quality of life for these patients.
