Vitapex® is known to promote healing of periapical scars and facilitate skeletogenesis. It is used in routine clinical practice as a root canal filling material after pulpectomy or for the treatment of infected root canals. We report a clinical case of overfilling of Vitapex® from the apical foramen into the mandibular canal that caused inferior alveolar nerve hypoesthesia.A woman in her twenties presented at a local dental clinic for treatment of an infected root canal of the left mandibular second molar and received a Vitapex® injection. After the treatment, she presented with sensory disturbance in her left lower lip and mental region. She was introduced to our department 1 week later. She was diagnosed with sensory disturbance in the left lower lip and side of the chin. A panorama X-ray radiograph revealed a radiopaque image suspected to represent a large overfilling of Vitapex® into the left mandibular canal. After extraction of the left mandibular second molar, the socket was opened. A vitamin B12 formulation was then administered to her, and a series of stellate ganglion blocks was performed. Three months after extraction, radiographic findings revealed that the radiopaque image in the mandibular canal had disappeared, and the sensory disturbance had mostly subsided 4 months after treatment initiation.

To investigate the effects of exercise stress on halitosis, we determined concentrations of cortisol and catecholamine in the blood and that of volatile sulfur compounds (VSC) in the expired gas. The experiments were conducted on healthy volunteers. All volunteers were measured for VSC (hydrogen sulfide, methylmercaptan, dimethylsulfide), cortisol and catecholamine (adrenaline, noradrenalin, and dopamine) before and after a footstool elevation movement. We found significant increases in hydrogen sulfide in the volatile expired gas and cortisol, adrenaline, noradrenalin, and dopamine in the blood in a comparison of before and after exercise. In addition, a significant positive correlation was found between hydrogen sulfide and adrenaline, hydrogen sulfide and dopamine. These results suggest that induced exercise stress is a factor that increases the concentration of sulfur compounds. In particular, the results strongly suggested that adrenaline and dopamine are involved in the increase of hydrogen sulfide.

A patient was diagnosed with pagophagia, a type of pica, during dental treatment and, on suspicion of anemia, was referred to an internal medicine clinic where she was diagnosed with severe anemia. We give a brief review of the literature concerning anemia and pagophagia.The patient was a 46-year-old woman who visited our clinic for dental treatment. Her medical history included noncontributory systemic findings, and she showed no abnormalities in facial features or otherwise.Intraoral findings: Several missing molars, but good overall oral health. Discolored gums presenting with anemic coloring. No abnormalities in the lips or tongue, but dental attrition visible throughout the jaw.Verbal examination revealed pagophagia of about 1kg per day, and so the patient was referred to a local internal medicine clinic on suspicion of anemia. A blood sample revealed Hb 4.0g/dl and a diagnosis of severe anemia was made. The patient was referred to a general hospital in the city for detailed full-body examinations and iron preparation drugs that corrected both the anemia and the pagophagia.The reported rate of anemia associated with pagophagia varies from 0.4 to 24.7%. However, it is clear that there is a link between pagophagia and iron deficiency anemia.

Tobacco smoking is a worldwide public health problem. Recently, there has been growing interest in smoking cessation. On the other hand, oral mucosal ulcers are common presentations encountered in daily practice. These ulcers may be caused by various etiologies.We report a case of refractory oral mucosal ulcer caused by improper use of nicotine gum. A male in his 50s presented to our department with an intractable ulcer in the oral floor existing for over 3 months. He had smoked 20 cigarettes per day for 25 years. He had given up smoking and been using nicotine gum for 6 months. He used two pieces of nicotine gum (2mg tablet) per day, and the gum was improperly placed at the oral floor for 3 to 4 hours per piece. An excisional biopsy was performed and revealed a mucosal ulcer without atypical cells. He was instructed to stop using nicotine gum at the first visit to our department, and the ulcer healed completely in 4 weeks.

An external dental fistula involves formation of a fistula or granulation as an excretion pathway in the jaws or face, due to chronic purulent odontogenic inflammation. We describe a case involving a 30-year-old male patient who had an external dental fistula-like scar in the right buccal region. A diagnosis of an external dental fistula, caused by an infected right mandibular first molar, was made; endodontic therapy was performed without symptomatic improvement, and the patient was referred to our university. Tenderness in the masseter region and scarring in the right buccal region were found upon examination. Diagnostic imaging revealed a cylindrical structure suggestive of an external dental fistula in the soft tissues. Removal of the external dental fistula was performed under general anesthesia and the course was good. Patients with an external dental fistula may show symptoms for a prolonged period before a definitive diagnosis is made; however, diagnosis can be facilitated by early, accurate imaging examination.

We have occasionally experienced cases with aberrant foreign bodies, such as fish bones or metal fragments of dental materials, in the oral region. Recently, there have been cases of serious injury due to piercing of the nose, lips, and other body parts. We report the case of a 49-year-old man with a needle in the floor of his mouth that had been used to pierce the tongue.The patient visited our department because of difficulty in swallowing and speaking. Macroscopically, only a slight redness on the right side of the oral floor was seen; the foreign body could not be felt on palpation. Panoramic radiography and computed tomography showed a sharp, straight metallic object extending from the floor of the mouth to the submental region. The object was located in the deep submucosal layer of the oral floor into the right suprahyoid muscles and was surgically removed from the inside of the right anterior belly of the digastric muscle using an extraoral approach. We chose to use general anesthesia because of the risk of bleeding and airway obstruction. The object was a metal needle 5 mm in diameter and 50 mm in length. The postoperative course until 1 year was uneventful.

We report the extraction of a mandibular third molar with six roots. The patient was a woman in her twenties. She was referred to our hospital with the chief complaint of gingival swelling of the right mandibular third molar region. Impacted teeth with many roots were found by dental X-ray imaging. We diagnosed pericoronitis and extraction was performed under local anesthesia. Extraction was easy, and no fracture was observed in any of the roots. There were no postoperative complications. As seen by CT, the extracted teeth revealed 7 cusps and 6 roots with 5 root canals.

In cases where wisdom teeth approach the mandibular canal, attention must be paid to potential injury of the mandibular canal during extraction.The present patient was a 61-year-old woman, in whom bony impaction of tooth 48 was causing pericoronitis. Computed tomography examination revealed that the inferior alveolar nerve was passing between the tooth roots.We selected a two-stage tooth extraction method. As the first treatment step, we removed the crown of tooth 48. During the second treatment step, we confirmed slight movement of the root and an enlarged periodontal ligament cavity after a 6-month transition period. During extraction of the root, the periapical alveolar bone was first cut using an ultrasonic bone cutting instrument, and root partition was then performed. Surgical invasion into the inferior alveolar nerve and soft tissue was minimized through the use of an ultrasonic bone cutting instrument. In difficult extraction cases such as this, we believe that use of the two-stage extraction method and an ultrasonic bone cutting instrument is effective.

Despite the considerable amount of literature on the positioning of ectopic impacted third molars, few reports have described cases of distal movement in the jawbone. In the present study, we describe our experience in treating a patient whose impacted lower third molar migrated over a 12-year period from the distal region of the second molar to a position inferior to the coronoid process.The patient was a 37-year-old man who first visited our facility in April 2012 with a chief complaint of right facial swelling and pain. Radiography revealed complete inverse impaction of the lower right third molar into a position inferior to the coronoid process, with a cyst-like radiolucent area including the crown spreading to the distal region of the lower right second molar.A radiograph from 12 years earlier showed that the lower right third molar was horizontally impacted distal to the lower right second molar. We therefore concluded that this lower right third molar had migrated apically over a 12-year period due to being displaced by the coronal lesion. Histopathological assessment indicated that the lesion was a dentigerous cyst. It is now 1 year since we performed the surgery and the patient has made good progress without any relapse to date.

A 55-year-old male with myelodysplastic syndrome had been treated at the Hematology Department at our hospital. Swelling of the left cheek developed in the patient, which led to his referral to our department. Since blisters and distinct dark red plaques were noted on the right forearm as well as the lower limbs, a dermatological examination was requested. Biopsy of the skin rash was performed; the biopsy result and clinical course led to the diagnosis of cheek phlegmon associated with Sweet's disease. We provided treatment for the infection and Sweet's disease. The patient received transfusions of peripheral stem cells. He has had a good outcome for 3 years and 6 months.

Currently, it is known that various abnormal cells including various normal cells and cancer cells form and secrete vesicles having a lipid bilayer membrane, and these membranous vesicles are called extracellular vesicles. Extracellular vesicles are classified into three types: apoptotic bodies, microvesicles, and exosomes. In this paper, we focus on exosomes, which have recently been attracting attention as a new cell-cell communication mechanism, and their formation mechanism. The isolation and purification methods are outlined, mainly regarding their usefulness and future potential in the early diagnosis of cancer, based on the cytobiological characteristics of exosomes.

Granular cell tumors are rare soft tissue tumors, derived from Schwann cells. About half of them occur in the head and neck, but a case with tumor arising in the zygomatic region has not been reported to our knowledge. We report a case of granular cell tumor arising in the zygomatic region. A 57-year-old woman was referred to our hospital because of cheek swelling. MRI findings showed a benign tumor, so the patient wished follow-up. However, the tumor gradually grew in size for 11 months, as was confirmed by MRI. Since the patient desired removal of the tumor, the operation was performed by the intraoral and subcilial approach. The histopathological diagnosis was granular cell tumor. Judging from the operative finding, we supposed the origin of the tumor to be the zygomaticofacial nerve which is a branch of the maxillary nerve. Twenty-six months after the operation, there was no sign of recurrence.

We report a case of schwannoma of the left lower lip in a 17-year-old female. A schwannoma is a tumor thought to be derived from Schwann cells and is rarely seen in the lip. On initial visual and palpation examination, a nodular, elastic hard, mobile mass was found on the left lower labial mucosa, which was suspected to be a benign tumor. Contrast-enhanced magnetic resonance imaging (MRI) showed a homogeneous contrast effect on T1-weighted images, negating malignant findings. Aspiration cytology showed no atypical cells. There was no rapid growth of the tumor during follow-up. The patient was diagnosed as having a benign tumor of the lower lip and the tumor was enucleated under local anesthesia. The pathological diagnosis was an Antoni A-type schwannoma. The patient is progressing well with no postoperative motor or sensory deficits.

Schwannoma is a benign tumor originating from Schwann cells, occurring rarely in the masseter muscle. In this report, we describe a case of schwannoma in the masseter muscle. A 35-year-old man was referred to our hospital because of swelling of the left cheek. A painless elastic hard mass was palpable in the left cheek. No abnormalities were found in the skin, oral mucosa, or cervical lymph nodes. MRI T2-weighted images showed a high signal area with 43×37mm internal nonuniformity and clear boundaries. Although malignant atypical cells were not detected by fine-needle aspiration and incisional biopsy, no definitive diagnosis was obtained. The lesion was diagnosed as a benign tumor of the masseter muscle and resection was performed under general anesthesia. It was located in the masseter muscle without any adhesion to surrounding tissues. No nerves were continuous with the tumor. The tumor was 45×40×30mm in size and was covered with a capsule. Histopathological diagnosis was schwannoma. After the operation, left facial nerve palsy was recognized, but it was completely cured 3 months after the operation. In addition, neither masseter atrophy nor masticatory function was observed. Two years have passed since the operation without recurrence of the tumor.

Oral lichen planus is an intractable chronic inflammatory lesion with dyskeratosis, appearing more commonly on the buccal mucosa. Here we describe a case of oral lichen planus starting on the bilateral buccal mucosa in a 70-year-old female patient that showed great improvement. The patient's condition gradually improved after treatment with cepharanthin, an alkaloid agent extracted from Stephania cepharantha Hayata. A review of some additional literature pertaining to probable mechanisms of action is included.

Many cases of accidental insertion of an iatrogenic foreign body during dental therapy involve radiopaque items such as dental bars, syringe needles, inlays, implants, etc. In such cases, the size and shape of the foreign body are determined by plain X-rays, and upon confirming the location of the accidental insertion in the CT, the surgical procedure is considered in detail to avoid causing secondary damage while extracting the foreign body. We report two cases we experienced, in which we extracted a metallic foreign body that had been accidentally inserted in the inside and outside of the mandible during tooth extraction.

Sialoliths commonly occur in the submandibular gland, and parotid gland sialoliths, especially parenchymal sialoliths, are rare. As a minimally invasive surgery, we report here endoscopic removal of a parenchymal sialolith of the parotid gland under local anesthesia.A female in her 40s with swelling and pain in the left buccal region was referred to our department for endoscopic removal to avoid extraoral removal after diagnosis of parotid sialolith in another hospital. Computed tomography showed that the parenchymal sialolith of the left parotid gland was 1.7×1.4×1.0 mm in size. The patient underwent endoscopic removal of the sialolith under local anesthesia as minimally invasive surgery. Complete removal was performed and the postoperative course was uneventful without complications such as swelling of the parotid gland.

Denosumab is a bone antiresorptive agent for use in patients with osteoporosis or metastatic cancer of the bones. A recent meta-analysis revealed that denosumab is associated with an increased risk of developing medication-related osteonecrosis of the jaw (MRONJ) compared with bisphosphonate (BP) treatment or placebo, although the increased risk was not statistically significant between denosumab and BP treatments. This paper presents the case of an 83-year-old man with MRONJ in the left maxilla caused by the use of denosumab for prostate cancer with multiple metastases to lymph nodes, bone and lungs, which improved by minimally invasive treatment after withdrawal of denosumab. The patient was given a subcutaneous injection of denosumab every 4 weeks for a period of 17 months. He had no history of receiving bisphosphonates or radiation therapy. We performed careful examinations and treatment with antibiotics, local irrigation and removal of as many necrotic bone chips as possible every 2 weeks. Finally, the remaining sequestrum was removed 10 months after the cessation of denosumab. The affected area was epithelialized within 19 days.
