Oral mucosal lesions associated with foreign body injuries can have various origins, but traumatic lesions of the oral mucosa caused by other organisms are rare. Such cases thus require special knowledge for diagnosis. We report a case of oral stings from spermatophores of Todarodes pacificus, the Pacific squid. The patient was a 31-year-old woman who cooked the internal organs of a raw T. pacificus for lunch. She experienced a sharp pain on the tongue and buccal mucosa when eating the organs. On checking the oral cavity, she identified multiple white objects with a worm-like appearance sticking into the tongue and oral mucosa. Attempts to remove these objects herself were unsuccessful. She then visited the emergency department of our hospital. We examined the oral cavity and found multiple white objects appearing to be parasitic worms sticking into the tongue and oral mucosa. Attempts to remove the objects with forceps were unsuccessful because of tight attachment to the mucosa. Removal was thus achieved by making slight incisions under local anesthesia. The specimens showed a white spinate shape and were about 4mm long. Endoscopic examination of the upper digestive tract after treatment of the oral cavity revealed no additional foreign bodies. The final pathological diagnosis was spermatophores of T. pacificus.

Fibromyalgia syndrome is a disease characterized by chronic pain and multiple tender points over the entire body. The cause of the disease is unknown, and patients are sometimes have various uncertain complaints. In this paper, we report a case of temporomandibular disorders (TMD) accompanied by fibromyalgia.The patient was a 26-year-old woman who received treatments for autonomic imbalance and panic disorder at a psychosomatic clinic. She complained of strong malaise, headache, tinnitus, insomnia, and constipation. She also had bilateral pain of the masticatory and neck muscles and around the temporomandibular joints. The range of maximum mouth opening was 23mm. The patient had edge-to-edge occlusion in the molar region and slight open bite in the incisor region.She received a diagnosis of temporomandibular disorders of type I and fibromyalgia. The patient was successfully treated with a stabilization splint for temporomandibular disorders and antidepressants for fibromyalgia.

Concool F®is a chemical mouthwash containing chlorhexidine gluconate that is used for the treatment of periodontal disease and halitosis. We report a case of gingival necrosis caused by incorrect use of Concool F®A 52-year-old woman was referred to our hospital because of gingival necrosis. One week before presentation, she went to sleep after putting a cotton roll soaked in a large amount of Concool F®solution (0.36 % chlorhexidine gluconate) on the upper gingiva to reduce bad breath. She noticed bleeding and a painful ulcer in the upper gum from the maxillary right lateral incisor to the left second premolar.Whenever a mouthwash agent containing chlorhexidine gluconate is used, we must be cautious about its usage and dosage and instruct the patients on proper use.

Intracranial and intraorbital complications of paranasal sinusitis constitute true surgical and medical emergencies. Owing to the availability of improved antibiotics, however, oral surgeons seldom encounter severe infections leading to death. We present a severe case of cavernous sinus syndrome associated with intraorbital cellulitis, intraorbital abscess, and cavernous sinus thrombosis primarily due to odontogenic sinusitis. This syndrome was considered to have a mortality rate of 100% before the development of improved antibiotics. Even now, the mortality rate is 13.6%, and the rate of sight loss is 22.7%. That patient was a 29-year-old man with multiple caries. We drained the maxillary sinus and intravenously administered antibiotics with gamma globulins. We were fortunately able to save his life without compromising the patient's quality of life, by collaborating with neurosurgeons, ophthalmologists, and otolaryngologists.

Oromandibular dystonia is characterized by involuntary contraction of the masticatory and tongue muscles, causing difficulties in mastication or speech. Muscle afferent block (MAB) therapy by intramuscular injection of lidocaine and alcohol is aimed at reducing muscle spindle afferents. We treated 37 patients with oromandibular dystonia by intramuscularly injecting 5 to 10ml of 0.5% lidocaine with 0.5 to 1ml of 99.5% alcohol. The muscles for injection were chosen from among the masseter, the inferior head of the lateral pterygoid muscle, the anterior belly of the digastric muscle, the genioglossal muscle, the medical pterygoid muscle, the sternocleidomastoid muscle, and the trapezius muscle. The effect of therapy was assessed subjectively on a linear self-rating scale ranging from 0 (no improvement) to 100 points (complete cure). All patients showed clinical improvement with reduced EMG activity in the affected muscles. The mean number of injections was 10.1±5.8. The overall subjective improvement rate was 60.8±25.4%. Maximal mouth opening (26.0±7.7mm) in patients with restricted mouth opening increased significantly (<I>p</I><0.0001, <I>t</I> test) after treatment (37.1±7.6mm). Some patients had tenderness, stiffness, or swelling of the muscles after repeated injection. The discomfort disappeared spontaneously after discontinuing therapy. MAB therapy is an effective means of treating oromandibular dystonia that has no major side effects.

A case with fresh gunshot wound penetrating from the left lateral neck to the mouth angle, which was caused by pistol shooting during a conflict between gangs, was reported and discussed by us.The patient, a 41-year-old male, was shot probably with a 38-caliber revolver from behind. Its entrance was on the left rear of the neck, and the exit hole at the left mouth angle. The route through the body: the bullet passed inside of the mandible, where it caused a crashing fracture of the body in the molar region while breaking the lower prosthesis. But, he was very lucky that the important blood vessels and nerve bundles were not injured, although the route was very close to them. He was transported to our Dept. that same day and operated on under general anesthesia for removing foreign bodies, uniting and fixing the jaw fracture, and also for reconstructing the mouth angle, while we sanitized the wound and sutured the soft tissues at each place. At last, a tracheotomy was performed, to prevent suffocation from postoperative swelling. The progress after the operation was good, and he was discharged three weeks later. After 3 years he is now healthy and in prison.

To investigate the efficacy of aciclovir for herpetic gingivostomatitis, changes in local lesions and fluctuations in local virus titer were compared between a treated group of patients given oral aciclovir (4 patients, 7 sites, 36 specimens) and a control group of patients not given aciclovir (3 patients, 5 sites, 15 specimens). Specimens were able to be taken from the same site for several days in succession in all patients. The results demonstrated improvement in clinical symptoms in the treated group from day 2 of treatment. Likewise, a tendency towards cure of local symptoms was noted remarkably earlier in the treated group than in the control group. In addition, assessment of the virus titer of specimens taken daily from the same site revealed that the virus was not isolated from local specimens as early as after 1 day of treatment up to 3 days of treatment in the oral aciclovir group. The results indicated that oral aciclovir is therapeutically effective for herpes simplex virus and that the drug should be administered for at least 3 days.

Several types of osteotomy have been performed for correction of mandibular prognathism, retrognathia and assymmetry.The injury of the inferior alvolar nerve as a complication were evaluated in 35 patients after the surgery.1. Anesthesia, hypesthesia and paresthesia of the lip and mental area were observed in all of the patients (35 cases) in early stage after the operation.2. 70.8% of the patients who were treated with sagittal splitting osteotomy were recognized as S4 (Highet's standards) within a year.3. The Average of the sensory nerve conduction velocity (S.C.V.) of normal was approximately 60m/sec.Nerve action potential could not be recorded in early stage and gradually returned to normal S.C.V.from 20 weeks after the surgery.4. Complete return of the sensation was recognized within 40 weeks after the operation which mandible were moved less than 10mm.5. There is no difference of return of sensation between circumferencial wiring and bone screw fixation after sagittal splitting osteotomy.

An odontoma is an odontogenic, tumor composed of enamel, dentine, and cementum, commonly less than 30 mm in diameter. We describe a large compound odontoma arising in the left anterior region of the mandible.A 16-year-old boy was referred by an orthopedist to our hospital for evaluation of a radiopaque lesion in the left side of the mandible. Clinical examination revealed a bony-hard swelling in the left anterior region of the mandible at presentation. The left mandibular canine and lateral incisor were not erupted. Radiographic and CT examinations showed a large, circumscribed, radiopaque lesion, measuring 30×40×28mm and surrounded by a thin radiolucent area accompanied by two impacted teeth. There were many small tooth-like structures within the lesion. The clinical diagnosis was odontoma. The tumor and the impacted teeth were surgically removed by an intraoral approach under general anesthesia. The tumor was covered by a thin capsule and consisted of 321 small tooth-like structures. The histopathological diagnosis was a compound odontoma. The clinical course has been uneventful for 4 years 3 months after surgery.

A prospective study was undertaken to evaluate dry socket (alveolar osteitis) in 1146 patients who surgically underwent extraction of impacted third molars. Dry socket occurred at a total rate of 5.4%; 27 cases occurred in males and 35 in females. There were no sexual differences. The prevalence of dry socket was highest: patients 40 years of age or over, followed by those from 30 to less than 40, 20 to less than 30, and under 20 years old.

An air-turbine handpiece is used for bone cutting and tooth dissection during extraction of an impacted lower third molar. However, subcutaneous emphysema and mediastinal emphysema may develop as advanced complications. Six patients had emphysema caused by the use of an air-turbine handpiece in our department during the last 10 years. Mediastinal emphysema developed in 3 patients. The route of the air was examined by CT scanning. The findings suggested that the air extended from a lingual sparse part of the extraction cavity to the sublingual space, submandibular space, masticator space, pterygomandibular space, lateral parapharyngeal space, carotid sheath, retropharyngeal space, and finally to the mediastinum. Since the pterygomandibular space communicates with the contralateral side, air easily invades this region.

Removal of mandibular third molars is one of the most common operations in oral surgery. Hypoesthesia of the lower lip occurring after the extraction of third molars is a serious complication, requiring a prolonged time for recovery. In this study, we investigated factors potentially affecting the incidence of hypoesthesia.A total of 781 mandibular third molars extracted at our clinic in 2002 were examined. There were 17 cases (2.2%) of hypoesthesia of the lower lip. There was no relation of gender, difficulty of extraction, or the skill of the operator to the incidence of hypoesthesia. In contrast, the incidence of hypoesthesia strongly correlated with age and the root position of mandibular third molars with respect to the mandibular canal.Eleven of the 17 cases of hypoesthesia (64.7%) resolved within 1 month, and 16 of the 17 cases (94.1%) resolved within 6 months. The patients who had hypoesthesia for more than 1 monthwere significantly older than those who recovered from hypoesthesia within 1 month and were all female.These results might be useful when informing patients about potential complications of tooth extraction.

We describe three patients (1 man and 2 women; age, 28 to 83 years) with herpes zoster of the trigeminal nerve that developed after dental treatment. The patients presented with toothache or periodontal disease as initial symptoms. Ten cases of herpes zoster occurring after dental treatment, have been reported previously. The initial symptom was toothache or periodontal tissue discomfort in most cases, and the age of the patients ranged from 7 to 73 years. Symptoms of herpes zoster appeared within 2 days after dental treatment in half of the patients. Although the relation between dental treatment and the occurrence of herpes zoster is unclear, we should include herpes zoster in the differential diagnosis when a patient presents with toothache or periodontal tissue discomfort.

We usually use Vitapex® as a root canal filling. This report describes a case of inferior alveolar nerve hypoesthesia caused by overfilling a root canal with Vitapex®.Case: A 23-year-old woman was referred to our hospital because of hypoesthesia of the inferior alveolar nerve.She had undergone treatment of 7 with root canal filling using Vitapex® one week earlier at another clinic. On the following day, she had hypoesthesia of the skin of the right side of the chin. X-ray examination showed a radiopacity in the right mandibular canal.After 4 months of conservative management, hypoesthesia decreased.Soon after, we extracted 7.Her subsequent course has been uneventful, and only a small hypoesthestic area remains.

We report a rare case of brain abscess secondary to mandibular odontogenic infection. A 50-year-oldman developed an abscess of the infratemporal fossa, masticatory myositis, and temporal myositis caused bylower first molar marginal periodontitis. Incision and drainage were performed by an intraoral approach, andantibiotics were administered intravenously. On the 8th disease day, vomiting occurred, but responded to anantiemetic drug. On the 9th disease day, extraction of lower first molar and adrasion was performed, resulting inthe alleviation of local symptoms. However, a persistent headache occurred, CT and MRI scans revealed a brainabscess and subdural abscess in the temporal lobe, immediately above the skull internal base. The patient wasgiven a diagnosis of brain abscess caused by odontogenic infection. The abscess almost disappeared after conservativetherapy administered at the department of brain surgery, and no sequelae were noted. The abscess apparentlyexpanded directly and continuously from the skull base through the foramen ovale and foramen spinosum.This case emphasizes the need to diagnose brain abscess and subdural abscess as complications of odontogenicinfection.

Thirty patients with the temporomandibular disorders were treated with “Kakkonto”, one of the most famous traditional drugs for chronic diseases with pain.“Kakkon-to” was given orally in a dosage of 7.5g 3 times daily before meals for two weeks. Clinical evaluation was carried out at seventh and fourteenth day after administration about spontaneous pain, pain with jaw movement, muscular tenderness, complications, and side effects. These symptoms were rated on a scale of 0 to 3 (0=no symptom and 3=severe). Two cases were dropped because of further administration of another analgesic for severe temporomandibular joint pain. 22 of 28 (78.6%) patients were improved at the therapy completion. 6 cases (21.4%) showed significant improvement, most of those had complications such as stiff shoulder and headache. Side effects were observed in 5 cases, such as slight nausea, vomiting and so on. It is suggested that “Kakkon-to” is a useful drug for temporomandibular disorders.
