Infectious myositis, an infection of the skeletal muscles, is a rare condition and potentially life-threatening if not detected and treated in the early stages. This clinical entity may arise from various pathogens, such as bacteria, fungi, parasites, and viruses. A propagation of contiguous infection, penetrating trauma, vascular insufficiency, or hematogenous spreading of microorganisms can cause infectious myositis. Though several cases have been reported in large muscle groups in the lower extremities, there are only a few reports on infectious myositis of the masticatory muscles. We report three cases of infectious myositis presenting jaw pain and trismus. Unlike a common head and neck infection caused by the spreading of odontogenic origin, the early diagnosis of infectious myositis was difficult because no specific lesion suspected to be the infection source was observed in the physical examination and the plain radiographs. Advanced imaging modalities such as computed tomography and magnetic resonance imaging, and laboratory evaluation is useful for the early detection of infectious myositis.

Herpes zoster is caused by reactivation and multiplication of a latent varicella-zoster virus infection. Reactivation can frequently occur in older adults and immunosuppressed individuals. It is hypothesized that this is related to an aging society and a corresponding increase in the number of people with underlying chronic diseases, such as cancer and diabetes, that lower immunity. Clinically, the patient complains of pain, and a vesicular rash presents on one side of the face up to the midline in the dermatomes associated with the affected ganglion. Herpes zoster of the oral mucosa is rare. When oral lesions do occur, they are most often concurrent with pathognomonic unilateral linear vesicular skin lesions, facilitating both clinical diagnosis and management of the condition. Cases limited to the oral mucous membrane alone are most unusual. Treatment includes antiviral agents and analgesics for pain control. Antivirals should be administered within 72 hours of onset. Early diagnosis and treatment are important to avoid complications, such as postherpetic neuralgia. The present case report describes the adequate management of a patient diagnosed with shingles which affected the right side of the face and oral cavity. In addition, a literature review is presented.

This case report describes about recurrent herpetic stomatitis mimicking post-root resection complication. A 49 year-old male patient was diagnosed vertical root fracture of the mesiobuccal root of his left maxillary first molar (#26). The mesiobuccal root was resected following root canal treatment of the same tooth. 19 months later, the patient presented with pain on left hard palate after a barbecue party. Intra oral examination revealed a gum boil-like blister at the hard palate corresponding to the apex of the palatal root of #26. On clinical examination, there was bleeding on probing and the periodontal pocket depth was measured less than 5 mm with no tooth mobility. On a periapical radiograph, periodontal ligament space widening was observed. Tracing the sinus tract with gutta percha cone was attempted, however, it was impossible. Extending the field of vision, small multiple round ulcerations were observed at the palate front which caused pain to the patient. Therefore, the pain was considered a non odontogenic and the patient was referred to the department of oral medicine. The patient was diagnosed recurrent herpetic stomatitis and after 3 days of antiviral medication, the pain and ulceration were subsided.

The author observed and analyzed the age, sex, chief complaint and radiographic finding of sixty-one cases of benign odontogenic tumors seen in Yonsei Medical Center, for the period of Jan. 1979 to Aug. 1989. The results were as follows: 1. Benign odontogenic tumors of 61 cases included 52 cases (85.3%) of ameloblastoma and odontoma, and 9 cases of other lesions. Radiographically, the border of the lesions were well-defined. 2. Ameloblastoma constituting twenty-seven cases (44.3%) occurred the average age of 31.1 years and had a 3:1 male predominance. The most common complaint was swelling (20 cases, 74.0%) and followed by pain (13 cases, 48.2%). Radiographically, the most common site was mandibular body area (74.0%) and the lesions were mainly multiocular radiolucency; in 17 cases (63.0%) and unilocular radiolucent lesion were seen in 10 cases (37.0%). 16 cases (59.3%) showed the resorption of roots of adjacent teeth. 3. Odontoma constituting twenty-five cases (41.0%) discovered at the average age of 16.9 years and had a 3:2 male predominance. The most common complaint was delayed eruption of tooth (8 cases, 31.0%) and 7 cases (27.0%) detected on a routine radiograph of the area. Radiographically, 17 cases (68.0%) were of compound type and 8 were of complex variety and compound odontomas were common in the anterior maxilla, whereas complex odontomas occurred more frequently in the posterior mandible. 19 cases (76.0%) showed the impaction of adjacent teeth.

Primary intraosseous squamous cell carcinoma (PIOSCC) is very rare type of squamous cell carcinoma (SCC) that occurs within the jaw and arises from remnants of odontogenic epithelium with no connection to the oral mucosa. This study reports two cases of PIOSCC of the mandible. Reported in this article are two cases of PIOSCC of the mandible that were treated with resection and reconstruction using a fibular free flap. The first case was a 36-year-old male patient who complained of right mandibular pain. Computed tomography (CT) and panoramic radiograph revealed a large radiolucency in the mandibular ramus area. At first, an odontogenic keratocyst was tentatively diagnosed, and an excision procedure was carried out at another clinic. A final biopsy after cyst enucleation revealed well-differentiated SCC, so we proceeded with segmental mandibulectomy and reconstruction using a fibular free flap. The second case was a 48-year-old male patient with left mandibular pain. CT and panoramic radiograph revealed irregular radiolucency in the mandibular angle area near tooth #38. At first, osteomyelitis was tentatively diagnosed, and a curettage was carried out. A later biopsy revealed well-differentiated SCC, so segmental mandibulectomy and reconstruction with a fibular free flap were secondarily performed. Our two cases have had no recurrence. The facial appearance of both patients is satisfactory, and the neo-mandibular body created using a fibular bone transfer displays adequate bony volume.

Osteomyelitis in the oral and maxillofacial area is a relatively uncommon inflammatory disease that occurs due to odontogenic causes such as endodontic infection, facial trauma, insufficient blood supply caused by some medical conditions, and iatrogenic postoperative infections. Among them, the incidence rate of candida osteomyelitis in this area is minimal; therefore, no consensus on the diagnosis, treatment, and prognosis has not been established yet. With the increasing number of immunocompromised elderly patients, candida osteomyelitis of the jaw is expected to become more prevalent. In this case report, we present an 81-year-old male patient with candida osteomyelitis of the jaw, including the maxillary and ethmoid sinuses.

Toothache is a common complaint in the dental office. Most toothaches have their origin in the pulpal tissues or periodontal structures1). These odontogenic pains are managed well and predictably by dental therapies. One of the most frequent encounters and most confusing phenomena with which the dental diagnostician must deal is the problem of referred pain. The most important step toward proper management of a toothache is to consider that the pain may not be of dental origin. And Patients with orofacial pain, especially those in chronic pain, present a diagnostic and management challenge for the practitioners. There are many structures in the head and neck that can produce heterotopic pains felt in the teeth and other structures. Once referred pain is suspected, the true source of the pain must be located in order to render effective therapy. With increased interest in temporomandibular disorders and orofacial pain, many studies of accurate diagnosis and differential diagnosis about orofacial pain have been established. The purpose of this paper is to present a case for pansinusitis which produced pain referral in teeth and mimicked the symptoms of migraine.

The purpose of this clinical study is to assess whether calcium hydroxide as an intracanal medication affects post-treatment pain in teeth especially odontogenic pain which comes from inflammation of the pulp and periradicular tissues when compared with no intracanal medication. From 213 patients who has been treated 237 root canals due to significant pain (moderate-to-severe) we recorded their age, sex, treated tooth, degree of pain, pre-operative states of the tooth. We classified patients into 2 test group; Group 1 (not gain intracanal $Ca(OH)_2$), Group 2 (gain intracanal $Ca(OH)_2$). Through the survey from the patients, we let them write down the occurrence and degree of post-treatment pain in 4hours, 2days, 7days after treatment as none, mild, moderate or severe. The followings were evaluated ; the overall incidence of flare-ups, the overall incidence of post-treatment pain in each group at each time period , the incidence of post-treatment pain in each group at each time period as related to pre-operative states of the teeth These were compared statistically with Chi-square analysis (p < 0.05). Under the condition of this investigation, no difference was observed in the incidence of post-treat-ment pain between the two groups. Therefore, $Ca(OH)_2$ as intracanal medication had no effect on preventing or decreasing the post-treatment pain.

If patients complain about sudden ill-fitting occlusal sensation(acute malocclusion), a dentist has to consider many possible causes about that. Acute malocclusion is characterized its sudden onset and mainly can be caused by teeth and its related structure problem. But we always keep on mind that acute malocclusion also can be caused by temporomandibular disorders In this 3 cases of acute malocclusion, evaluating by patient history, clinical and radiographic findings, we diagnosed them as 1. Lateral pterygoid muscle spasm, 2.. Retrodiscitis, 3. Osteoarthritis. Through this non-odontogenic acute malocclusion cases, we emphasize the key of diagnosis is on comprehensive and careful patient history taking and clinical examination.

The occurrence of odontogenic epithelium in the well of a dentigerous cyst is a well known entity. This epithelium usually remains inactive and does not have clinical significance. However, these small inactive islands of epithelium may be stimulated, resulting in an ameloblastoma. Therefore correct diagnosis and proper treatment are very important. A 15 year-old boy came to the outpatient clinic on August 13, 1979. The Chief complaint was pain, difficulty in mouth opening and swelling of the right mandible of 1 month's durations. With the X-ray filming, it was revealed that dentigerous cyst had been originated from the third molar, occurred in posterior region of the right mandible involving the 1st and the and molar and the portion just beneath the sigmoid notch area. Pus discharged from the gingival sulcus distal to the 2nd molar and it was sure that the cyst had been infected. Enucleation performed with careful excision of all cyst wall was successfully carried out, and recovery and heading were rapid and uncomplicated.
