    It is very important to develop sound masticatory function in children. In the present study, we evaluated the occlusal contact area, the average bite pressure and the average bite force in intellectually impaired children. We examined occlusal status in 14 intellectually impaired children attending a certain institution (boys 7, girls 7, average age 5.3) as compared with that of 64 children attending a certain kindergarten (boys 34, girls 30, average age 5.6) (control group).
    We analyzed the occlusal contact area, the average bite pressure and the degree of bite force in 78 subjects. Subjects were instructed to bite pressure sensitive sheets (DENTAL-PRESCALE®, Fuji Photo Film, Co.) and the results were evaluated by an analyzing computer (OCCLUSER FPD 703®, Fuji Photo Film, Co.). We calculated the asymmetry index (AI) of bite force which was defined as a percentage of the difference in bite force between the left and right sides compared to the sum. We also conducted a questionnaire survey of their parents, and we evaluated a temporomandibular symptom and its occasion or primary cause. We obtained high reproducible data from both groups.
    There was no significant difference in bite force between these two groups, but AI in the intellectually impaired children group was significantly larger than that in the control group. The questionnaire survey showed that the number of subjects with bruxism, allergy, and one-sided mastication was significantly larger among the intellectually impaired children than among the controls.

    Recently the orthodontic treatment of impacted teeth by traction became common as the dental material and technique developed. Although there are numerous cases in maxillary incisor and canine in particular, but rare cases exist in mandible.
    In this article, we experienced a rare case of impacted lower lateral incisor, which was found due to the prolongedretention of deciduous teeth in a 9 years 3 months old boy. The impacted lateral incisor was inclined distally and caused the resorption of roots of primary canine and first primary mol ar. By the long-term treatment with surgical fenestration and orthodontic traction, the lateral incisor was aligned in the dental arch.

    Sialolithiasis is a common disease in adults, but in childhood it is rare. It frequently occurs in the submandibular gland, but seldom arises in the minor salivary gland. We report a case of sialolithiasis in the buccal mucosa of the minor salivary gland in a child. An 8-year-old girl visited our department because of a painless swelling in the right buccal mucosa. The clinical diagnosis was a mucous cyst and excision was performed. Histopathological examination of the surgical specimen showed a salivary calculus in the mucous mass of the connective tissue, and the tumor was diagnosed as sialolithiasis in the minor salivary gland. Post operative finding has been good, with no evidence of recurrence as of 8 months after the operation.

    We encountered a patient with the completely impacted upper second premolar and completely impacted lower first molar with a follicular dental cyst, which were moved to normal dentition position by surgical and orthodontic treatment.
    The patient was a 10-year-old boy, who was brought to our department with a chief complaint of delayed eruption of 6_??_, showing trasmissive X-ray images, in 6_??_, on December 8, 1999. Intra-ral findings showed that ED_??_were missing, part of the tooth crown of 5_??_erupted, and the second premolar was unerupted.
    ED_??_were remaining, and 76_??_were unerupted. By panoramic X-ray, 5_??_was bucco-lingually impacted, and 6_??_was impacted in a low position with a slight mesial inclination, showing transmissive X-ray images containing the tooth crown of 6_??_. In January 2000, the cyst in 6_??_was excised, and fenestration was performed under local anesthesia. On the fifth month after fenestration, it was confirmed that 6_??_started to slightly move in the direction of the tooth crown. Since part of the tooth crown of 6_??_between 7_??_and 5_??_was confirmed approximately 1 year thereafter, after leveling 75_??_, and bending an over wire in which an open coil spring was incorporated using 0.16 and 0.18 round wires, 7_??_was distally moved, and a space for the eruption of 6_??_was maintained. Although the tooth crown of 6_??_was confirmed 2 months thereafter, since mesial inclination was marked, 6_??_was moved to almost the normal position by guiding with slight traction after placing brackets. Conventional orthodontic treatment was then performed to establish Class I occlusal relationship, with a combined used of Class II elastic. Two years after the first examination, although X-rays showed a slightly curved tooth root, a good stability of 6_??_in the jaw bone was obtained.
    On the other hand, after fenestration in 5_??_, a plate was placed to maintain a space for the eruption of 5_??_. After observing the clinical course for approximately 10 months, 5_??_started to rotate in the normal eruptive direction, and when placement of brackets became possible approximately 1 year after, 5_??_showed the same condition as that of the normally erupted teeth. It is considered that after completing dynamic orthodontic treatment, a long-term course observation is necessary.

    An ectopic eruption tooth in the nasal cavity was rarely observed in daily dental treatment. Therefore, the number of case reports from the otorhinolangologist was much more than those from dentists and oral surgeons. We encountered an 8-year-old boy complaining of a white foreign body in the left nasal cavity. On radiological examination, a tooth-like whitish structure was observed, and it was diagnosed as an ectopic supernumerary tooth. Under general anesthesia, the supernumerary tooth, which looked like a canine tooth, was extracted. After the operation, the patient's course was going well and the symptom of nasal obstruction has disappeared.

    Sialolithiasis is the formation of a calcified stracture within the gland on ductal system of a salivary gland. It occurres commonly in adult, rare in children. We have recently encountered a case of sialolith in a child. The patient a nine year old boy who complained swelling of the right submandibular region. After radiographic examination, it was diagnosed sialolith of the sublingual caruncula. The patient was operated under local anesthesia and extirpated the calculus. In a childhood, it is very rare to find the sialolith because of the rapid saliva outflow and chemical property.
