Most neoplasm of the floor of the mouth are squamous cell carcinoma. They originate from anterior midline floor of the mouth and penetrate into the sublingual gland. Invasion of the mandible is a late manifestation. Lymphatic spread is the submaxillary and subdigastric nodes and advanced lesions of them produce severe pain, The initial step in managing patients with cancer pain is the oncology therapy in the form of radiotherapy, surgery, or chemotherapy, alone or combined. When oncologic therapy is ineffective, the pain must be treated by systemic analgesic, psychologic, neurostimulating, regional analgesic,and meuroablative techniques. We successfully treated with gasserian ganglion block on the left side and mandibular nerve block on the right side with pure alcohol in the patient having severe submandibular, lower lip and tongue pain.

Neuroblastoma is a common malignant tumor of the sympathetic nervous system in childhood, arises from embryonic neural crest cells. The period of tooth development is matched with peak times of diagnosis and treatment of neuroblastoma. The intensive multimodality treatment including radiotherapy and chemotherapy is used in patients with neuroblastoma has been shown to have late adverse effects and disturbances in dental development like tooth agenesis, microdontia, enamel hypoplasia and short roots. A 8-year old girl had been on medication and radiotherapy for neuroblastoma since she was 15 months old at Department Pediatrics, Chonnam National University Hospital. Oligodontia, microdontia, and short root formation was notable in clinical and radiological examination. Mobility of lower permanent incisor was detected and measured at about degree 2. Resin wire splint using mini-screw implantation on buccal alveolar bone was conducted for maintenance of mandibular incisors and alveolar bone. Excessive mobility has been eliminated and maintained well so far. Further treatment is planned for re-evaluation of mobility, preventing dental caries and regular oral hygiene management. Although we need further evaluation, this treatment could be one of alternative therapy for those who have similar dental anomalies.

Majority of toothache is caused by abnormality of pulpal or periodontal tissues. However, there are numerous nonodontogenic sources that may be responsible for pain felt in the tooth. Nonodontogenic toothache may result from muscle, maxillary sinus, neuropathic, neurovascular, even cardiac and psychogenic problems. Myofascial pain is one of the most common abnormality characterized by palpation of a hard band which acts as the trigger point that causes stiffness and fatigue of the muscle, referral pain in tooth, tension-type headache, and hyperalgesia. Masseter muscle particularly induce referral pain in maxillary and mandibular molars. This case reported the treatment of the pain in right mandibular molar originated from myofascial pain of the right masseter. The pain is improved by general and reversible treatments such as muscle exercise, physical therapy, and medication. Nonodontogenic toothache should undergo proper differential diagnosis in order to avoid unnecessary dental treatments, such as endodontic, periodontic treatment, and tooth extraction, which would fail to alleviate the symptom of the patient.

The purpose of this study was to evaluate treatment outcome and prognosis of the patients with orofacial pain disorders who visited for treatment in the Department of Oral Medicine, Dankook University Dental Hospital from January 2002 to December 2004. Orofacial pain disorders were categorized into TMD(myogenous, arthrogenous and muscle-joint combined TMDs), neuropathic pain disorder, oral soft tissue disease and complex condition simultaneously having more and two aforementioned categories and treatment period, method and treatment outcome were evaluated. The results of this study were as follows; 1. Average longevity of treatment period was the longest in the neuropathic pain, followed by soft tissue disease, complex conditions, arthrogenous TMD, muscle-joint combined TMD and myogenous TMD in order. 2. When treatment methods were largely categorized into pharmacologic, physical and oral appliance therapy, pharmacologic therapy was used the most frequently for the patients with neuropathic pain or oral soft tissue diseases, oral appliance therapy for those with arthrogenous TMD and physical therapy for those with myogenous TMD. 3. Of physical therapeutic methods used in our clinic, EAST and microwave was employed the most frequently in the patients with myogenous TMD, ultrasound for those with arthogenous TMD and LLLT for those with neuropathic pain or oral soft tissue disease. 4. In comparison with change of pain after treatment, there existed a tendency that pain from neuropathic pain disorders persisted while pain from TMD was getting better or totally disappeared. 5. Concerning the change of mouth opening range in the TMD subgroups, there was no significant difference among the subgroups but significant difference existed among opening ranges, indicating comfortable maximum mouth opening increased the most following treatment. Improvement of active range of mouth opening was the most considerable in those with disc displacement without reduction. It can be said on the basis of the findings from this study that various treatments currently used for the orofacial pain showed good results with TMD in regards with pain control and improvement of function, suggestive of favorable prognosis, while neuropathic pain or soft tissue disease was the clinical conditions difficult to resolve, requiring a long and persistent treatment.

The purpose of this study is to evaluate the position of the mandibular foramen and location and morphological characteristics of the mandibular lingula using Cone-Beam Computed Tomography (CBCT). Mandibular CBCT images of children aged 6 - 16 years were collected. A total of 180 patients were divided into 3 groups, 6 - 7, 10 - 11 and 15 - 16 years, with 30 male and female patients per group. Either side of the ramus was analyzed. The shortest distances from the anterior, posterior, superior and inferior border of the ramus to the mandibular lingula were measured. The shortest distance between the mandibular lingula and the mandibular foramen was also measured. The vertical distance from the mandibular lingula and the mandibular foramen to the occlusal plane was measured. The shapes of the mandibular lingula was classified into 4 types according to the criteria. The distances of the mandibular lingula from the anteroposterior and vertical reference points of the ramus increased in all directions with age. The distance between the mandibular lingula and the mandibular foramen also increased with age. The location of the mandibular lingula and the mandibular foramen in relation to the occlusal plane moved upwards with age. The most common shape of the mandibular lingula was triangular, followed by nodular, truncated and assimilated, and there was no difference in the shape according to age. It is recommended that the horizontal insertion point of the anesthesia from the anterior border of the ramus increased to 17 mm, 18 mm, and 19 mm according to the age groups. It is also suggested that the vertical insertion point increased by 2 - 3 mm, 5 - 6 mm and 9 - 10 mm above the occlusal plane according to the age groups.

음식물을 씹거나 삼키는 정상적인 하악운동이외에 악안면 근육의 활동에 의해 상, 하악 치아가 접촉하거나, 비정상적인 근육활동이 있을 때 이 현상을 이갈이(Bruxism)이라 합니다. 이갈이 습관은 대개 수면중에 나타나나 깨어 있는 상태에서도 비정상적인 근육수축을 관찰할 수 있읍니다. 이러한 현상을 저작근의 근전도(Electromyogram, EMG)를 기록하거나, 구강내에 장치된 원격계측장치로 치아접촉을 관찰함으로써 정상적인 저작이나 연하작용과 비교할 수 있습니다. 이갈이의 발생빈도는 학자들에 따라 서로 다르게 보고되고 있으며, 수면중 이를 가는 사람들은 대부분 이갈이 습관을 알지 못하며, 단지 10%정도만이 이가는 소리를 알 뿐입니다. 본문에서는 이갈이와 수면중의 생리적 현상과의 관계, 저작근에 미치는 영향과 이갈이 발생에 대한 중치신경의 작용을 검토함으로써 이갈이를 이해하는데 도움이 되고저 합니다.

The aim of this study was to evaluate the position of the mandibular foramen in panoramic radiographs of Korean children to provide information for successful inferior alveolar nerve block anesthesia. 240 panoramic radiographs of 7 to 15-year-old boys and girls were analyzed. The subjects were divided into 4 groups in boys and girls according to their age.; 7-8, 9-10, 11-12 and 13-15 years old. The shortest distances from the center of the mandibular foramen to the anterior border of ramus, to the posterior border of ramus, to the antegonial notch and to the mandibular notch and the perpendicular distances from the center of the mandibular foramen to the occlusal plane were measured. The following results were obtained. 1) Although the relative position of the mandibular foramen in the ramus of mandible tended to move anteriorly for both genders with age, the vertical position did not correlate with age. 2) The mandibular foramen moved upward in relation to the occlusal plane with age, and showed statistically significant correlation with age(p<0.05). 3) The mandibular foramina of boys, when compared to those of girls, were located more superiorly in relation to the occlusal plane and more superiorly and posteriorly in the ramus of mandible.

Bilateral sagittal split ramus osteotomy(BSSRO) of the mandible is an essential and commonly used procedure to correct dentofacial deformities and malocclusion. The possible complications associated with BSSRO include inferior alveolar nerve injury, bleeding, temporomandibular disorder, unfavorable fractures, and clinical relapse. The incidence of facial nerve palsy after orthognathic surgery recently reported is 0.1%. The probable etiologies have included facial nerve compression, complete or incomplete nerve transection, nerve traction, and nerve ischemia from anesthetic injection. Postoperative facial palsy is one of the most serious complications because it reduces the quality of life and significantly reduces social interaction. The case of a 24-year-old patient who underwent bilateral sagittal split ramus osteotomy is described. The medical records and postoperative photographs were reviewed in detail to collect information on the clinical course, treatment, and outcomes.
