Multiple myeloma is a lymphohematopoietic disorder leading to abnormal hemostasis and significant pathologic changes of skeletal system. It induces multiple circular or oval-shaped radiolucent lesions which are characterized by 'punched-out appearance'. The surrounding trabecular bone normally shows no significant sclerotic reaction. Multiple myeloma patients may visit dental clinics, without perception of the disease themselves, due to discomfort from edema of orofacial region, oral ulcers, tooth mobility, pain or gingival bleeding. Multiple myeloma is susceptible to various complications, including delayed hemostasis and infection, which could occur during routine dental treatment such as periodontal and surgical operation. For radiographic diagnosis of multiple myeloma, common radiologic features of this tumor could be visualized by panoramic radiographs in the dental clinics, and further medical examinations and treatment can be recommended as a result.

Burkitt's lymphoma is a malignant tumor that commonly occurs in the jaws of children of Central Africa. It originates from the lymphatic tissue, and it shows rapid growth. Clinically, it is commonly found in children between age of 3 and 8. When it is found in the jaw, facial swelling, mobility of deciduous teeth, and early eruption of posterior teeth can also be found. Upon radiographic examination, radiolucent lesions with irregular border can be observed. Histologically, macrophage can be seen among tumor cells, and this special pattern is called "starry-sky" appearance. In this case, 3 year-old male patient came to our hospital with left facial swelling and severe mobility of deciduous molars. He was diagnosed as Burkitt's lymphoma based on clinical, radiographic, and histologic examination. He is being treated with chemotherapy and progress seems promising.

Ectopic eruption is defined as the eruption of the tooth in an abnormal position or orientation. In the molar region, ectopic eruption may cause distal root resorption and premature exfoliation of the neighbor teeth and uncontrolled space loss is followed. Prolonged partial impaction of the permanent molar may also cause undetected caries or abscess formation of the neighbor teeth. While 66% of ectopically erupting permanent molars are corrected spontaneously without treatment, the treatment is necessary for the irreversible ectopic eruption cases. The optimal treatment approach depends on a number of factors including the clinical eruption status of the molar, amount of enamel ledge and the mobility of the neighbor tooth, and the presence of pain or infection. This case report presents the results of treatment of the ectopically erupting maxillary first permanent molars and mandibular second molars using elastic separators or modified Halterman appliance with or without surgical approach.
