Gingival fibromatosis is a rare condition characterized by varying degrees of gingival hyperplasia. Gingival fibromatosis usually occurs as an isolated disorder or can be associated with a variety of other syndromes. It usually appears at the time of eruption of permanent dentition but, can develop at the time of eruption of the primary dentition and rarely at birth. It may deform palatal contour and subsequently restrict the tongue movement, resulting in interference during speech and mastication. In addition, it incapacitates maintenance of normal lip closure. A 14-month-old girl visited the department of pediatric dentistry, Yonsei University Dental Hospital, for the congenital gingival overgrowth. There was no one in the family, who showed similar pattern of gingival growth. The intraoral clinical examination revealed generalized severe gingival enlargement throughout the maxillary and the mandibular arches. Enlarged gingival tissue was pink and had firm consistency. She was referred for chromosomal analysis, which confirmed absence of any known syndrome. Under local anesthesia, "Punch-biopsy" was performed on the labial area, and the specimen was histologically diagnosed as gingival fibromatosis. For she did not have any medical problem nor familiar history, she was diagnosed as having idiopathic gingival fibromatosis. Regarding her age and behavior, close follow-up was decided.

Cerebral palsy, a range of non-progressive syndromes of posture and motor impairment, is a common cause of disability in childhood. Self-injurious behavior(SIB) is deliberate harm to the body without suicidal intend, often involving repetitive actions that cause tissue damage. One of the most common orofacial self-injurious behavior is chewing tongue, lip or oral mucosa. This kind of SIB in children is not common in normal children. High occurrence rates are observered in cases of syndromatic, mentally retarded children, and children with congenital disease. Various methods such as behavior modification, behavior control by drugs, body restraints, application of dental appliance, surgery and extraction of teeth have been suggested to control those self-injurious behavior. Using mouthguard as one of dental applainaces is the most conservative and appropriate method in terms of reducing oral self-injurious habits and protection of tissue. This case report describes a child with cerebral palsy who presented with self-injurious ulceration of lip and buccal mucosa. A modified mouthguard was effective in preventing self-injurious oral trauma in a child with cerebral palsy.

We investigated brain activity during the performance of the intelligence task by a science high school student group (n=8) and a foreign language high school student group (n=5). Both groups scored in the top 1% on intelligence tests (science high school group: RAPM mean score=34.0, WAIS mean IQ=139.6; foreign language high school group: RAPM mean score=33.8, WAIS mean IQ=147.2). Analysis of brain activity during the performance of the intelligence task showed that both groups had brain activity in certain areas, including the left and right prefrontal cortex, parietal cortex, and anterior cingulate. The science high school group showed the highest activity in the right parietal cortex, which is related to visuo-spatial working memory, whereas the foreign language high school group showed the highest activity in the left prefrontal cortex, which is related to verbal working memory. The foreign language high school group showed higher brain activity than the science high school group in the left precentral gyrus which is related to the motion of the tongue and lips. These results show that the science high school group utilized the visuo-spatial area, whereas the foreign language high school group utilized the verbal area during the performance of the intelligence task. This suggests that the major thinking process differs depending on the gifted students' primary field of study, although they are doing the same task.

The purpose of this study was to examine the differences in men's thinking and attitude on prostitution and gender based on the previous experience of buying sex. It was an exploratory survey for planning future studies and movements for changing a way of thinking in relation to prostitution. A total of 1328 male adults(above 19 years) completed a questionnaire consisting of general thinking of buying sex, tolerance limit of sexual behavior, and sex role egalitarianism. The respondents answered differently in the probability of paying for sex in future and the way how to get a sex information according to the previous experience of buying sex. Those respondents who had paid for sex, had higher scores on three types of sex attitude measures than those who did not. The previous experience of buying sex was significantly correlated with sub-factors of buying sex, tolerance limit of sexual behavior, and sex role egalitarianism except for the sub-factor on recognizing a sex worker as a victim (factor 4 of buying sex). These results suggest that men who had paid for sex had more traditional gender-stereotypes and attitudes. Implications and limitations of this study were discussed in a feminist perspective.

Orofacial dystonia is a neuromotor disorder that causes irregular or repetitive movements of the face, lips, tongue, and jaw involuntarily, also called tic disorder. Edentulous patients with these symptoms experience functional and aesthetic problems, including difficulty using complete dentures, speech and swallowing difficulties, and orofacial pain. In this case, for a patient with orofacial dystonia who experienced complete edentulism at a relatively young age, restorative treatment was performed with a maxillary complete denture with bilateral posterior zirconia occlusal surfaces and a mandibular implant-supported fixed prosthesis, and continuous smile training was performed. The aim was to improve the aesthetics of facial muscles. As a result of the treatment, the patient was very satisfied with not only improved chewing function and aesthetics, but also regained psychological stability and was able to lead a normal daily life, so we would like to report this.
