Background/Objectives: Odontomas are the most common mixed odontogenic tumors and may cause impaction of adjacent teeth and masticatory disorders. Treatment of tooth impaction caused by the presence of odontomas is related to their stages of root development and their positions in the alveolar bone. The aim of this case report is to present the combined surgical and orthodontic treatment in growing patients with odontomas and to discuss the treatment outcomes. Methods: Two growing patients, an 8-year-old boy and a 17-year-old girl, with large odontomas in the posterior maxillary region of the maxilla were presented. The tumors were found during a radiological examination, and the first molars on the affected sides were impacted due to the presence of odontomas. Results: The treatment plans included the surgical removal of the tumors. In the case of the younger patient, the impacted developing molar erupted spontaneously in the oral cavity one year and two months after surgery. An orthodontic traction of the impacted molar was successfully applied in the older patient. Conclusions: The presence of a large odontoma in the posterior segments may lead to a displacement and impaction of neighboring molars and malformation of their roots. Spontaneous eruption of the affected molar can be expected if the tumor is diagnosed and removed early before its root formation is completed; otherwise, an orthodontic extrusion is needed. Interdisciplinary cooperation is important to diagnose and plan the dental treatment in young patients with odontomas.

Background/Objectives: Vascular anomalies represent a complex group of conditions including vascular malformations and haemangiomas. Haemangiomas are benign tumours that have an endothelial origin. In contrast, vascular malformations are characterized by the abnormal dilation of vessels without proliferation. Depending on the extension of the disease, there is a higher risk of life-threatening haemorrhages that may occur during simple dental procedures. The aim of this case report is to present the interdisciplinary treatment for patients with venous malformation and to discuss the possible dental management of these patients. Methods: A 66-year-old male patient with an extensive venous malformation of the head and neck was referred for a tooth extraction. The venous malformation involved lips, buccal mucosa, tongue, and floor of the oral cavity. Its proximity to the tooth requiring extraction was associated with a high risk of severe bleeding. Results: Prior to the treatment, CBCT and CT scans were performed to confirm the extensions of the lesion and visualise its margins. Considering the possible risks related with venous malformation, the procedure consisted of tooth removal in a hospital setting with control over severe bleeding complications. Conclusions: The presence of an extensive vascular malformation in the head and neck region is burdened with a higher risk of haemorrhages during simple dental procedures. The radiological and clinical planning enables the choice of an accurate treatment strategy to avoid possible difficulties. In cases where such complications cannot be avoided, it is important to perform the treatment in a hospital setting with the cooperation of maxillofacial surgeons.
