The prevalence of childhood cancer has been estimated to be 1 to 1.5 per 10,000 persons. Although childhood cancer is less common than adult cancer, about 3000 new patients are registered per year. Childhood cancer is the second leading cause of death in children, after accidents. Owing to progress in diagnostic and therapeutic techniques, more than 70% to 80% of patients are now cured. Because cancer develops in 1 per 500 to 600 children aged 0 to 14 years, it is estimated that about 1 per 300 of the entire population has had childhood cancer. Childhood cancer is characterized by a high prevalence of blastomas and sarcomas, derived from fetal tissue and precursor cells. Tumors can arise in various sites, and tumor type is related to age and sex. Generally, childhood cancers are sensitive to antitumor agents and radiotherapy; however, response rates, remission rates, and long-term survival rates differ depending on tumor type, molecular biologic and cellular genetic characteristics, and tumor extension. Treatment is therefore decided according to expected outcomes, predicted on the basis of risk factors.  The development of childhood cancer is mainly related to genetic predisposition, the fetal environment from conception to birth, and genetic abnormalities occurring during postnatal growth and development. Unlike adult cancer, the effects of lifestyle and environmental factors are minimal. Studies of genetic diseases associated with high risks of cancers such as retinoblastoma and chromosomal and genetic analyses of cancer cells in diseases such as neuroblastoma and leukemia have led to the identification of many oncogenes and tumor suppressor genes, contributing to a better understanding of the mechanisms underlying the development and progression of cancer, the identification of risk factors, and the development of molecular targeted therapy.  Progress in epidemiology, molecular biology, and cellular genetics is changing childhood cancer from an incurable to a curable disease. How to improve patients' quality of life after treatment (i.e., a decreased rate of late complications) is becoming an important part of the treatment strategy.

In clinical oral surgery, we often encounter cases of infants who fall down while holding a toothbrush in their mouth and receive an oral injury from a toothbrush. This particular case was that of a 5-year-old girl who accidentally injured her left buccal mucosa with a toothbrush. After the injury, she was immediately brought to the hospital by ambulance. When she arrived at our hospital, the toothbrush was still embedded in the oral wound. We examined her oral wound by computer tomography (CT). We found that the tip of the toothbrush was located in the vicinity of the left medial pterygoid muscle, and there was neither damage from the toothbrush itself nor on the maxillary artery and basal skull. We removed the toothbrush carefully under local anesthesia, and then cleaned the wound by adequate normal saline and administered antibacterial drugs (SBT/ABPC) intravenously. No serious complications were seen after the treatment.It is strongly suggested that in such a case an immediate examination be conducted by CT in order to avoid severe complications and to insure a good healing process.

Cat-scratch disease (CSD) is a zoonosis characterized by lymphadenopathy in a patient with a history of cat contact. CSD is caused by Bartonella henselae infection and is a common cause of regional lymphadenopathy. The manifestations include erythema or papules at the site of injury and regional lymphadenitis in the initial stage of infection.   We report the case of a seven-year-old boy who presented with swelling of the buccal. CT showed extensive lymphadenopathy in multiple lymph nodes in the buccal and submandiblar regions. He had a history of contact with cats. Serologic examinations for IgG and IgM titers to Bartonella henselae were performed by an indirect fluorescence assay. This assay revealed positive serum antibody titers for Bartonella henselae.   On the basis of these results, CSD was diagnosed, and the patient was given an antibiotic for 14 days. After that, the patient recovered, with no recurrence.

There are two primary locations in the mouth where frenula are identified; lip frenula and cheek frenula exist in the oral vesitibule and a lingual frenulum exists in the oral cavity proper. All frenula appear as a ruffle or fold of the mucous membrane.   Few disturbances originate in a morphological abnormality; almost all originate in a malpositioning of the adhesion, and present various symptoms. In cases where abnormal adhesion of the frenulum causes oral problems and treatment is needed, age seems to be an important factor. Ankyloglossia causes breastfeeding difficulties, articulation disorders, pronunciation disorders, and chewing and swallowing difficulties in the infant and young child. An abnormal cheek frenulum, which influences oral hygiene, can lead to gingivitis and periodontitis in young and middle-aged people. An abnormal cheek frenulum interferes with the stability of dentures when teeth are lost in old age; it makes it difficult to set them properly.  Because there seem to be many abnormalities in the lingual frenulum and the upper lip frenulum of infants and young children, we focused on assessment, diagnosis and surgical procedures (frenectomy) for both types of abnormality.

We report the case of an eight-year-old girl who had dysplasia of the teeth, suspected to be induced by chemotherapy. The patient was born at full term by normal delivery, and was diagnosed to have neuroblastoma (stage IV-S) by ultrasonography. Tumor resection was performed 15 days after birth, and chemotherapy was performed for 12 months after that. She has had a good prognosis since then.   The examination of the oral cavity revealed morphological abnormalities of the crowns of the right and left upper central incisors. X-ray showed findings of morphological abnormalities of the four central incisors and deficiencies in tooth germs of the right and left lower lateral incisors.   The dysplasia of the teeth in this patient was considered to be caused by chemotherapy, because the period of chemotherapy doses coincided with the formation period of those teeth.

We need to accomplish not only esthetic restoration of the deformity of the lip, but also functional reconstruction of the orbicularis oris muscle. Many procedures have been developed and modified to result in the best outcomes of cleft lip repair. Among several procedures, the rotation advancement method is personally preferred because it discards a minimal amount of tissue.   The authors have been performing surgery by the rotation advancement method, which results in a nearly straight scar to improve the outcome of philtrum plasty. We have been using Mimura's design in the vermillion to repair the labial tubercle. We have also been applying the muscle suspension method, which entails suturing the nasal and nasolabial muscle bundles to the anterior nasal spine for functional reconstruction. This report describes our techniques and points out important details.

The patient was an 8-year-old boy, who consulted our department on May 25, 1999, because of a black spot in the maxillary gingiva. He had under-gone application of saforide® in CB_??_ in a dental clinic 5 years previously. Thereafter, he noted a black spot in the surrounding gingiva, but because of no pain, it was left untreated. Recently, the patient consulted a dental clinic due to an increase in the size of the spot. He was then referred to our department. Intraoral examination revealed a flat dark brown spot (11×6mm) in the buccal gingiva around 2_??_, showing infiltration into the surrounding tissue. There was also a localized flat black spot (1×1mm) besides the dark brown spot. Based upon these clinical findings pigmented nevus or malignant melanoma was suspected. As a result of biopsy performed on May 25 using cryosurgery, histopathologically they were diagnosed as cellular blue nevi. On June 25, the spots were removed together with the surrounding gingiva and periosteum. The course has been uneventful these 8 months after the surgery without a sign of recurrence.

Cationic soap have a strong sterilizing action and few side effect in regularly using concentration. And so, it is generally in use for a sterilizer and a disinfectant. High concentrated cationic soap, however, have a strong corrosional action, and some dead cases caused by this disinfectant were reported. We experienced an iatrogenic accident of corrosion of oral mucosa caused by high concentrated benzethonium chloride.A case report: The patient was a 3 month-old baby. At plastic surgery of lip, we disinfected intraoral mucosa, by mistaken, with 10% benzethonium chloride solution. At postoperative 1st day, the patient had a fever of from 37.8° to 38.5°C, and his tongue was swelling and per os was a little. At 3rd day, it was found that widespread oral membrane were errosive and/or necrotic; hard and soft palate, upper alveoler and lower molar part, and lower part of left side tongue. His fever was at 38°C leveled, activity was poor, face color was pale and limbs were cold. Additionally, he had severe diarrhea.

Ankyloglossia is a commonly observed medical condition of which there has been very little investigation. Our purpose in the present study was to determine the appropriate time to conduct the corrective operation.  The study group consisted of 104 children with ankyloglossia, 78 males and 26 females, with an average age of 4.7 years. Speech disorder was the most frequent chief complaint. The patients found it most difficult to pronounce the Japanese syllables beginning with the sound /r/. Frenulectomy was the most frequently performed therapeutic procedure. The results of our investigation indicated that the operation should be performed on patients aged four or older.

We reported a case of complex odontoma in a 3-year-old 1-month female infant.She was consulted with a complaint of an unerupted mandibular left first deciduous molar. Based on X-ray examination, we found that the tooth was impacted, and a calcificated mass was observed surrounding the tooth. We enucleated the mass with the tooth surgically. Histopathologically, it was diagnosed as complex odontoma.This is a rare case of complex odontoma, which interferred with the eruption of the mandibular first deciduous molar.

The bone grafting to the alveolar cleft was once performed during the primary cheiloplasty. However, it was pointed out that this primary(early)bone grafting to the alveolar cleft affected the growth of the middle face and maxilla. Then, this procedure has been popularly performed to induce the eruption of the upper lateral incisor or canine(secondary bone grafting to the alveolar cleft: SBG). The main purposes of the bone grafting to the alveolar cleft are closure of oro-nasal fistula and stabilization of the dental arch. However, the most significance of this procedure is to make space for the eruption of the upper canine. Therefore, the SBG is now established to be one of the important treatment strategies for the cleft lip and palate children. In this review, the purposes, optimal timing, surgical procedure, and postoperative management of the popular SBG are described for trainees of oral and maxillofacial surgery.

Injuries of oral soft tissues often occur in children, who tend to hold pointed objects in their mouth. In most cases, the injuries are superficial and heal uneventfully. And serious cases are rare.We recently experienced a case of abscess in temporal fossa caused by piercing of a toothbrush into the submucosal tissue of the cheek. An 8 year-old girl was attacked by her younger brother while brushing her teeth by her mother and a toothbrush injured her left cheek. And inflammation of cheek extended to abscess in temporal fossa. However, under treatment included the incision and administration of antibiotics, the wound healed without serious complication and she recovered completely.
