Cleft lip and palate is the most common malformation in the craniofacial region. The patients with cleft lip and palate have functional problem such as, speech, feeding and respiratory as well as esthetic problem. So, treatment should be done by multidiciplinary team approach. The role of pediatric dentist in the team is advicement for feeding method, guidance of normal growth, caries control and preventive orthodontics. In cleft lip and palate patients, maxillary arch after cheiloplasty is usually collapsed by excessive tension of the scar. This collapse increase the difficulty of later orthodontic treatment. Therefore, the maxillary arch segments should be moved and retaind to normal position as soon as cheiloplasty is done to reduce the need and difficulty of orthodontic treatment. This concept is called by the early orthopedic treatment in cleft lip and palate. Also, this orthopedic appliance works as feeding applince to normal feeding and weight gain We reported two cases of early orthopedic treatment with favorable result in complete bilateral cleft lip and palate patients after cheiloplasty. Patients showed normal weight and their maxillary arch widths were increased.
保護者의 口腔保健官理態度와 乳齒列期 兒童의 齒苔指數와의 關係에 關한 硏究

The purpose of this research was to analyze the relationship between parents attitudes toward their children's dental health and dental plaque index. Dental plaque index was obtained through oral examination of 118 children(female 40, male 78) with primary dentition. The maintenance status of children's dental health though parents' aids was evaluated by means of questionaire to which 79 persons among the 118 children's parents answered. The results were as follows: 1. In children with primary dentition, toothbrushing together with toothbrushing instruction and continuous reinforcement had decreased plaque accumulation progressively. 2. Dental plaque index before toothbrushing showed that dental plaque was accumulated more in the buccal surfaces of teeth in the maxilla and in the lingual surfaces of teeth in the mandible. It was higher in the posterior teeth than in the anterior teeth and in the maxillary teeth than in the mandibular teeth. 3. Dental plaque index of children was inversely proportional to the level of education of their parents. 4. Those parents who have much knowledge of oral hygiene were more positive toward their children's oral hygiene.
역위 매복된 상악 중절치의 교정적 처치를 통한 치근 형성유도

미맹출된 상악 중절치는 비교적 흔히 임상에서 8세이상의 아동에서 관찰될 수 있다. 맹출실패의 원인으로는 치배의 비정상적인 발육이 언급되는데 아직 명백히 밝혀지지는 않았지만, 이는 외상이나 선행유치의 치근단 감염으로 유발될 수 있다. 본 증례는 외상의 병력이 없어 유치의 치근단 감염에 의한 상악 중절치의 매복을 고려해 볼 수 있다. 치아의 맹출과 Hertwig's epithelial root sheath 에 의한 지속적인 치근 발육을 유도하기 위해서는 외과적 노출과 가철성 장치를 이용한 교정적 견인이 치료방법으로 시행될수 있다. 본 증례는 역위 매복으로 인해 치근의 만곡이 예상되며 치근의 발육이 지연된 치아를 치근형성 전 조기에 가철성 장치를 이용한 교정적 견인에 의해 정상적인 맹출과 인접치와 유사한 치근 발육이 얻어졌다. 하지만 향후 완전한 치근 형성 유무에 대한 주기적인 검진과 부착치은 획들을 위한 치주적인 처치가 필요하리라 사료된다. It is a relatively common clinical experience to see an unerupted maxillary central incisor. This phenomenon is apparent at the dental age of almost eight years and over. Among the possible cause for failure of eruption, ectopic development of the tooth germ is mentioned. This is not fully understood but trauma or periapical imflammation of primary predecessors is accepted. The case with no history of trauma may be impacted by the periapical imflammation of primary predecessors. For bringing into the tooth eruption and the continued normal root development by the Hertwig's epithelial root sheath, there are early considered of surgical invention and orthodontic traction with removable appliance. We reported successful treatment for inverted maxillary central incisor with proper eruption and normal root development by forced eruption using removable appliance. But further observation will be required to evaluate the final root development state and amount of keratinized attachment gingiva.
