A fairy tale of information by word of mouth gets to this day with admitting the change of period. A fairy tale reflects the morality of the education of children. The late 17th century, the information by an author of classical literature collects and the literature genre of children begins to fix. In 1697, Perrault publicates and is a volume of eight volumes' tale. Perrault describes that female children guard against male by annexing a figurative allusion. Sara Moon of a photography artist in 20th century expresses this theme by symbolic expression of illustration. Her illustration brings about many questions and becomes conscious of the veiled significance of sentences by author's consideration. She deletes the Perrault's preccept in substitution of bed photography and she substitutes a wolf with a car or a dog and a shadow, etc .. The illustration of Sara Moon gets ready a foundation of early sex education as reflecting a period. Now, an illustrator gets to rebirth a fairy tail as a new dramatizer of today.

Thermoformed appliance, which has been recently introduced for dental usage, is an appliance made of thermoformed sheets and formed with positive or negative pressure under heat. Thermoplastic material is a kind of plastics and can be repeatedly softened by heat. It is classified into hard elastic foil, hard/soft compound foil and soft elastic foil, including BIOPLAST, BIOCRYL, IMPRELON, etc. It has been developed in 1969 and is available in various thickness, shape and color. There are two types of Vacuum former for thermoplastic materials; the pressure type and suction type. The former is much better than the latter for fabrication of various appliances due to its higher pressure. The authors have applied these appliances to some cases - chin cap, active retainer, individual Fluoride tray, mouth protector, bracket transfer mask, bruxism splint(night guard), Essix appliance - by pressure type Vacuum former($Biostar^{(R)}$). The thermoplastic appliances have numerous advantages such as simple procedure, short working time, clean and transparent product, less objectionable taste. But its outstanding advantage would be its excellent biocompatibility bacause it has no monomer and hence no tissue irritation. Although there is some limitations in its usage, it can be used widely for various purposes especaily for pediatric dentistry.

The purposes of this work were to assess the cognition of the registered nurse(RN) on oral and maxillofacial emergency treatment and to compare cognition of the RN with that of the 119 emergency medical technician(EMT). 450 RNs who were working at each of secondary hospitals in Jeju province had responded to the questionnaire. Independent sample t-test and chi-square test were used to assess the state of RN on dental emergency treatment and to compare RN with EMT. The question 'education time on dentistry in formal education' that marked '0 hour' and '1-3 hours' were 73.3% and 20.0%, respectively. The question 'refresher training class on dentistry' that marked '0 hour' and '1-3 hours' were 92.9% and 6.7%, aggregately 99.6%. The results showed low score in the question 'reduction of temporo-mandibular joint(TMJ)'($1.67{\pm}0.857$), 'fixation of dislocated TMJ'($1.70{\pm}0.853$) and 'post-avulsed tooth treatment'($1.78{\pm}0.774$) by 5-point Likert scale. Likewise, the scores were $2.02{\pm}0.806$ in the question 'treatment of maxillofacial trauma', $2.76{\pm}1.061$ in the question 'emergent care of avulsed tooth', $2.70{\pm}1.095$ in the question 'treatment time of avulsed tooth' and $2.79{\pm}1.056$ in the question 'mouth guard', respectively. Compared to EMT, results of RN showed a statistically lower figure(p<0.05) in all items compared except the question 'medicine control', and the question 'doctor care in emergency room' was borderline(p=0.069). From this study, it is necessary for RN and student of nursing science to be educated on the oral and maxillofacial emergency treatment for the initial management of injuries. Authors suggest further co-study and nation-wide research with nursing care.

Self-injurious behavior is defined as deliberated harm to one's own body without suicidal intent. It usually occurs as head banging or hitting, body hitting, skin cutting, or finger biting and includes ocular, genital, and self-inflicted oral mutilation. Self-injurious behavior can occur with mental retardation, coma, psychotic problem, poisoning, or character disorders. In pediatric patients, self-injurious behavior usually is reported to lip, cheek and tongue biting, and many kinds of dental management methods have been introduced to prevent self-injurious behavior patients from self biting. This report presents two self-inflicted oral mutilation patients who were all treated successfully with appliances such as modified activator without wire for retention, modified tongue-rake appliance and mouth guard.

Lesch-Nyhan syndrome is a rare disorder of purine metabolism, first described in 1964. The incidence is estimated to be 1:100,000 birth. It is an X-linked recessive disorder in which affected males have a virtually complete deficiency of the enzyme hypoxanthine guanine phosphorybosyl transferase(HGPT). This enzyme deficiency gives rise to excessive uric acid production and consequent hyperuricemia. Lesch-Nyhan syndrome is clinically characterized by mental retardation, choreoathetosis, spastic cerebral palsy, and severe self-mutilation behavior. Patient with Lesch-Nyhan syndrome mostly bite their lip, tongue and finger. In severe cases, partial or total amputation of the lip and tongue is common. Self-inflicted bites are often further complicated by secondary infection to injuried site as well as pain. And tissue loss by biting results in esthetic problems. This report presents a Lesch-Nyhan syndrome patient with self-mutilation, who have a destruction of perioral tissue, especially the lower lip. He was treated successfully with soft mouthguard, psychological and pharmacological method.

Lesch-Nyhan syndrome is a rare X-linked recessive genetic disorder. During purine metabolism, the hypoxanthine guanine phosphribosyl transferase (HGPRT) enzyme is deficient causing phosphoribosyl transferase to accumulate and resulting in excessive uric acid. Clinical symptoms include hypercalcemia, choreoathetosis, spasticity, mental retardation, and self-injury to lips, tongue or fingers. This results not only in pain caused by the self-injury but also secondary infection of the wound site and the esthetic damage of the soft tissue defect. Dental treatments include conservative methods using intraoral appliances such as soft mouthguards, fixed lip bumpers, and occlusal guards, and invasive methods such as extraction of all teeth or forming an artificial anterior open bite. We report two cases of Lesch-Nyhan syndrome patients with self-mutilation behavior; one was treated with a preservative method using a soft mouthguard, and the other was treated with extraction of all teeth.
