The initial symptoms of leukemia include oral manifestations such as gingival hemorrhage and swelling. In patients with these symptoms, attention should be paid to the early diagnosis of acute leukemia. This report describes three cases of acute myelogenous leukemia (AML) with initial manifestations in the oral cavity.Patient 1: A 32-year-old woman. Ulcer lesions of the oral mucosa were diagnosed as decubital ulcers, and symptoms did not respond to the application of steroid ointment. She also had appetite loss, general malaise, and bloody stools. Blood examination showed a low white-cell count (1,600/μl).Patient 2: A 52-year-old man. He received anti-inflammatory treatment and had pain at the mandibular third molar region and gingival swelling, but the symptoms did not improve. At the initial visit, pericoronitis of the mandibular third molar with fever and general malaise were observed. Blood examination showed a low white-cell count (2,300/μl) and remarkably increased myeloblasts (20 %) .Patient 3: A 54-year-old woman. She received medication to treat full-mouth gingival swelling. However, fever and general malaise persisted. Blood examination showed a high white-cell count (47,000/μl).All three patients were given a diagnosis of AML on bone marrow biopsy.When the patients present with oral symptoms such as gingival swelling and ulcers accompanied by fever and general malaise, blood examinations should be promptly performed for the differential diagnosis of acute leukemia.

Inferior alveolar nerve and lingual nerve injury is common in the field oral surgery. Nerve injuries are induced by extraction of impacted teeth, and implant impaction, and many cases require surgical nerve repair. Partial amputation injury case and the nerves complete amputation case are adaptation of the nerves surgical repair for severe nervous part equivalent to neurotmesis of the Seddon classification, but when nerves surgical repair is not performed immediately, traumatic neuroma can develop and cause neuropathic pain; accordingly, early diagnosis and treatment are important. The gold standard of nerve surgical repair was nerve end-to-end suturing, and autologous nerve graft. Nerve repair surgery can provide a reasonable result in improving sensation in the inferior alveolar and lingual nerve. More than 80% of patients experienced some improvement in sensation, and dysesthesia did not develop after surgery in any patient who did not have it before surgery. This article will be explained not only surgical therapy but also basic research on peripheral neuropathy to clinical practice.

Patients with jaw deformities frequently have psychological and social problems. There have been many reports on psychological status and satisfaction following orthognathic surgery as determined by quantitative methods. However, only limited information can be obtained by using a quantitative method because the patient’s psychological problems are complex. On the other hand, qualitative studies are suitable for clarifying the hypothetical construction of the phenomenon and patients’ experiences and processes. The purpose of this study was to examine the process by which patient’s psychological and social problems change from pre-treatment to post-treatment. The subjects were 6 female patients who had undergone orthognathic surgery 18 months ago. We conducted semi-structured interviews and performed analysis by a grounded theory approach. The patient’s anxiety started from the period of adolescence and was affected by the patient’s friends. Information on orthognathic surgery gave the patients hope and reduced their anxiety. The processes of psychological and social changes during and after treatment were affected by friends, family, and patients with the same disease. Patients had feelings of accomplishment, happiness, and confidence because they overcame various hardships, and they acquired active attitudes in social life.

We report a case in which an impacted supernumerary tooth migrated from the mandibular ramus to the mandibular coronoid process. A 19-year-old male underwent a panoramic X-ray for orthodontic treatment at the age of 14 years. An opaque region with a well-defined border was seen at the front edge of the right mandibular ramus. Since the right lower third molar was also present, the opaque region was diagnosed as an impacted supernumerary tooth. Imaging examinations, performed every 2 years, showed that the impacted supernumerary tooth gradually moved from the mandibular ramus to the mandibular coronoid process. Thus, the patient visited our department to undergo detailed examinations and treatment. On panoramic X-ray and CT performed at the patient’s first visit to our department, the impacted supernumerary tooth had a total length (root axis) of about 10 mm, the tooth axis was located at the upper end of the right mandibular coronoid process, and part of the tooth was located outside of the tip of the mandibular coronoid process. Under general anesthesia, the impacted supernumerary tooth was extracted. Since the mandibular coronoid process was thin, it was resected during removal of the supernumerary tooth. There was no trismus or mandibular deviation 1 year after the operation.
