  • Lesch-Nyhan syndrome is a rare X-linked recessively inherited disorder, caused by complete absence or decrease in activity of hypoxanthine guanine phosphoribosyl transferase(HPRT), an enzyme involved in purine metabolism. This enzyme deficiency gives rise to nephropathy symptoms, such as hyperuricosuria and hyperuricemia by excessive uric acid production and neuropathy symptoms, such as mental retardation, choreoathetosis and self mutilation behavior. Patients with Lesch-Nyhan syndrome have tendency to bite their lip, tongue and finger. In severe cases, partial or even total amputation of tongue or finger occur. Self-inflicted bites are often complicated by secondary infection to the injured site as well as pain. Furthermore tissue loss by biting results in esthetic problems. The dental management of self mutilation includes treatment with appliances such as soft mouth guard or lip bumper, extraction of all the teeth, and orthognathic surgery. We report a case of a 13 year-old boy with Lesch-Nyhan syndrome, who severely injured himself on his tongue. At first, conservative treatment using soft mouth guard was considered, but it could not prevent trauma on his tongue. Therefore, extraction of the lower anterior and posterior teeth was carried out.

  • Hypoxic ischemic encephalopathy(HIE) is a condition that occurs when the entire brain is deprived of an adequate oxygen supply and associated in most cases with oxygen deprivation in the neonate due to birth asphyxia. Children with HIE develop problems such as cerebral palsy, mental retardation, learning difficulties, and other disabilities. We hereby report the case of treating a child patient with HIE whose chief complaint of severe lingual ulceration. A 12-month-old boy referred to our hospital to treat ulcers of ventral surface of tongue. He has been suffering from lingual ulceration due to persistent tongue thrusting. He has bitten his own tongue involuntary. The ulceration was apparently seemed to be not healed because of the constant irritation by lower incisors. So we designed tongue protector to prevent lingual ulcers. The appliance was proved to be effective to reduce tongue trauma by lower incisors and periodic follow-up is needed.

  • With today's heightened interest in quality of life, leisure and sports activities were popular in the general public. Accordingly, the incidence of oral and maxillofacial injury are also rising. Use of a mouth protector to prevent the trauma of the oral and maxillofacial region is growing in importance, and among the mouth protector the mouthguard is the most commonly used. Mouthguard has been suggested to protect injuries by (1) preventing tooth injuries by absorbing and deflecting blows to the teeth; (2) shielding the lips, tongue, and gingival tissues from laceration; (3) preventing opposing teeth from coming into violent contact; (4) providing the mandible with resilient support, which absorbs an impact that might fracture the unsupported angle or condyle of the mandible; (5) preventing neck and cerebral brain injuries. Although mouthguard is effective for prevention of oral and maxillofacial injury, it is not widespread to athletes or general public and they are lack of awareness about the importance of mouthguard. We present the types and materials of mouthguard, things to consider when mouthguard fabrication, and the usage. This should be helpful in awareness about the importance and popularization of mouthguard.

  • 저작운동을 중추신경계와 말초조직의 작용에의해 일생동안 학습과 적응의 가정을 통해 이루어진다. 저작의 양상은 유치가 구강내에 맹출되면서 이루어지며, 상하악 치아의 접촉, 점막과 혀 및 치아상호간에 일어나는 접촉과 치근막의 고유수용기와 악관절 수용기등에 의해 조정되어 최종적으로 에너지소비가 적고 동통이나 불편함이 없이 최대의 효율을 나타내는 양상으로 된다. 그러나 원활한 저작과 하악은동을 이룩하기 위해서는 저작근, 악관절, 상하악 치아의 교합등이 서로 조화를 이루어야 한다. 만일 외상에 의해 악관절의 기능장애가 오면 저작근활동이 변화하고 이에따라 교합장애를 야기한다. 또한 치아를 상실하거나 대합치아간의 조기접촉이 있으면 교합장애가 원인이 되어 근육활동이 변화와 악관절 기능장애를 초래한다. 그리고 때로는 지나친 근육의 활동(이갈이, 지속적 긴장성 수축)에 의해 지나친 치아의 마모로인한 교합장애나 악관절장애를 일으킬 수 있다. 따라서 하악의 기능을 충분히 이해하기 위해서는 교합의 형태학적 관계와 더불어 저작계의 기능적인 면도 고려하여 그 상호관계를 검토하여야 하며 본문에서는 교합에 관련된 저작근의 작용과 이에 영향을 주는 요인 및 교합장애와 근육활동장애의 연관성에 관해 고찰코자 한다.

  • In this study, 1,495 cases of computerized data collected as disease entities of oral and maxillofacial injuries among patient visiting S university hospital located in Seoul in 2009 were analyzed and following results were obtained. It was found that the injury incidence in male was greater than in female (1.49:1), it occurred most frequently in the age of 7~14 years old (19.6%), and its most frequent cause was falling down (25.9%). Injuries occurred in other place including beach and open-air (24.7%) most frequently, often developed in anterior teeth (43.2%) and posterior teeth (43.1%), their incidence was relatively higher between 15:00~17:00 (10.4%) and 19:00~23:00 (7.1%) O'clock. In the relationship between causes of the injury and the diagnosis based on the international classification of disease), falling, fall, impingement, violence, traffic accident, sports and own making accident caused most frequently lip and oral open injuries (S01.5), open fracture of tooth (S02.51), close fracture of tooth (S02.50), close fracture of mandible (S02.60), close fracture of tooth (S02.50), respectively. From the above results, it is necessary to understand general characteristics of oral and maxillofacial injuries and to consider their trends for the establishment of systematic complement policies and for the performing safety training and public relations activities.

  • The first dental visit is recommended at the time of the eruption of the first tooth and no later than 12 months of age. However, even before the age of 1, children can visit the dental hospital for various reasons. The purpose of this study was to analyze the reasons for the dental visit of infant. From January 2006 to December 2015, medical records of infants who visited the Department of Pediatric Dentistry of Kyung Hee University were analyzed. The total number of patients was 419 (238 males and 181 females). The reasons for the dental visits were trauma (47.5%), natal/neonatal tooth (19.8%), dental caries (8.1%), teething problem (4.3%), abnormal frenum (3.6%), soft tissue swelling (3.6%), Bohn's nodule (3.3%), cleft lip and palate (2.9%), gingival neoplasm (1.9%), tongue ulceration (1.7%), oral examination (1.4%), enamel hypoplasia (1.2%) and abnormal temporomandibular joint sound (0.7%). According to this study, there were various oral diseases that could occur in infants. Since infants are usually cared by caregivers, pediatricians, and obstetricians, education of oral diseases of infants is needed to manage the oral symptoms properly.

  • Burning mouth syndrome(BMS) refers to a chronic orofacial pain disorder usually unaccompanied by mucosal lesions or other clinical signs. Tongue(anterior and lateral border) is found to be the most common site for the burning sensations in the oral cavity, and various oral sites may be affected including hard palate and lips. The etiology of this disorder remains poorly understood, but the various factors might be related with the pathogenesis of the BMS. These factors have been devided into local, systemic and psychological. Recently, there have been increasing reports that the pain of BMS may be neuropathic in origin. The complex and multifactorial etiology of BMS necessitates multidisciplinary approach for the management of these patients. Recently, several studies have reported that oral parafunctional habits could be related the pathogenesis of BMS, and tried to control the symptom of BMS with various methods. We reported the cases who had the symptom of burning mouth syndrome with removable anti-nociceptive appliance in the lower dentition.

  • Lesch-Nyhan syndrome is a disease caused by metabolic disorder of purine. General muscle stiffness and hyposomia are shown from infancy and symptoms can include involuntary or irregular movements of arms and legs, mental retardation, and compulsive self-mutilating behaviors. Self-mutilating behaviors begin at approximately the first year or sometimes at late teens. The patients bite their lips, especially lower lip, tongue, buccal mucosa, hands and fingers. Tongue and lips can be injured or mutilated in severe cases. As the patient gets older, self-mutilating behaviors become more serious and extensive and secondary infection of injured areas is possible. Periodic soft tissue damage due to self-mutilating may evolve to cancer. Medical treatment, appliance treatment, extraction of tooth and surgical operation was attempted to control self-mutilaing behaviors. We hereby report the case of child Lesch-Nyhan syndrome patient who has self-inflicted labial damage as chief complaint. When patient was treated with conservate therapy, such as removable or fixed appliance, the frequency of labial damage could be subdued and yielded favorable results.

  • Bruxism is extensively defined as a diurnal or nocturnal parafunctional habit of tooth clenching or grinding. The etiology of bruxism may be categorized as central factors or peripheral factors and according to previous research results, central factors are assumed to be the main cause. Bruxism may cause tooth attrition, cervical abfraction, masseter hypertrophy, masseter or temporalis muscle pain, temporomandibular joint arthralgia, trismus, tooth or restoration fracture, pulpitis, trauma from occlusion and clenching in particularly may cause linea alba, buccal mucosa or tongue ridging. An oral appliance, electromyogram or polysomnogram is used as a tool for diagnosis and the American Sleep Disorders Association has proposed a clinical criteria. However the exact etiology of bruxism is yet controversial and the selection of treatment should be done with caution. When the rate of bruxism is moderate or greater and is accompanied with clinical symptoms and signs, treatment such as control of dangerous factors, use of an oral appliance, botulinum toxin injection, pharmacologic therapy and biofeedback therapy may be considered. So far, oral appliance treatment is known to be the most rational choice for bruxism treatment. For patients in need of esthetic correction of hypertrophic masseters, as well as bruxism treatment, botulinum toxin injection may be a choice.
