Treacher Collins 증후군(TCS)은 두개안면 발육의 이상을 보이는 상염색체 우성 질환으로, 외이, 중이 및 이소골(auditory ossicle)의 형태이상과 상악골 발육 부전, 후퇴된 하악, 구개열 등의 특징을 보인다. TCS 환아의 경우, 청각 장애로 인한 환아의 불안으로 적절한 협조를 얻기 어렵고, 개구제한과 기도 확보의 어려움으로 인해 전신마취 하에 치과치료를 진행하는 것이 안전하다. 전신마취 시 하악 후퇴 등의 형태학적인 문제로 인하여 삽관의 난이도가 높을 수 있어 주의가 요구되며, 술 후에도 적절한 호흡의 유지를 위해 지속적인 감시가 필요하다. 마지막으로, 보호자로 하여금 구강 위생의 중요성이 강조되어야 한다.

Objectives: The purpose of this study is to examine correlation between subjective oral health status and oral-related appearance satisfaction of college students. 100 college students at a college located in Gyeonggi-do participated in the survey, oral examinations, and self-rated oral hygiene management ability tests. The data was then analyzed accordingly. Methods: Frequency test and chi-square statistical analysis were conducted on general characteristics and subjective oral health status, and SAS version 9.2 was used. Results: As a result of this study, students' subjective perceptions about oral health had positive correlation with oral-related appearance(p <0.05). It is noteworthy that those who responded on 'satisfactory' oral health status indicated that 16% 'unsatisfactory', 28% 'average' and 68% 'satisfactory' on oral-related appearance. Students' self-rated oral hygiene management ability and irregular teeth conditions were also found relevant in causing discomfort in interpersonal activities, whereas students responded 'satisfactory', 0.00%; 'average', 31.82%; 'unsatisfactory' 68.18% (p <0.05). Conclusion: This study suggests that oral-related appearance can have an impact on oral health status and that oral-related appearance can be a contributing factor to improve oral health status and therefore results in promotion of general health. In the future, further research should be considered about perception on oral-related appearance, oral health status and any resulting behavior changes.

Background: The purpose of this study was to compare the clinical safety and effect with and without additional submucosal midazolam to oral chloral hydrate and hydroxyzine when used for pediatric conscious sedation in a clinical dental environment. Methods: Thirty one cases of pediatric conscious sedations were performed in this study. Selection criteria included good health (ASA I), under 6 years old, 20 kg of body weight, uncooperative behavior and the need for sedation to receive dental treatment including anesthesia and restorative or surgical procedure for at least two teeth. In each visit, patients were randomly assigned into one of two groups; CH group: chloral hydrate (60 mg/kg), hydroxyzine (1 mg/kg), CH-M group: chloral hydrate (60 mg/kg). hydroxyzine (1 mg/kg) and submucoal midazolam (0.1 mg/kg). 50% nitrous oxide-oxygen was maintained during the sedation period Sedations were monitored using a pulse oximeter for estimating pulse rate (PR) and percutaneous oxygen saturation ($SpO_2$). Behavior response rated using Houpt's scale and need of restraint was assessed every 2 minutes through 30 minutes of operative procedure reviewing the videotape recording. Evaluation of overall behavior success was performed using modified overall behavior rate of Houpt's scale. Data was analyzed using t-test. Results: PR and $SpO_2$ for both groups remained within the normal values. The mean scores for sleep and movement of CH-M group were higher than those of CH group (P < 0.05). There were no significant difference in mean score for crying between two groups. The mean scores of overall behavior of CH-M group was higher than those of CH group (P < 0.01). Reinstraint of CH-M group was less required than that of CH group (P < 0.05). Conclusions: Oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) combined with submucosal injection of midazolam was safer and showed more improved sedation effect than oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) without midazolam for sedation of pediatric dental patients.

This study was performed to observe the micro-structure change of surface, behavior of oxide change of element, the component transformation of the alloy and the bonding strength between the porcelain interface in order to investigate effects of indium, tin on interfacial properties of porcelain fused to low gold alloy. Hardness of castings was measured with a micro-Vicker's hardness tester. The compositional change of the surface of heat-treated specimen was analyzed with an EDS and an EPMA. The interfacial shear bonding strength between alloy specimen and fused porcelain was measured with a mechanical testing system(MTS 858.20). The results were as follows: 1) The hardness value of alloy increased as increasing amount of indium addition. 2) The formation of oxidation increased as increasing indium and tin contents after heat treatment. 3) Diffusion of indium and tin elements increased as increasing indium and tin contents in metal-porcelain surface after porcelain fused to metal firing. 4) The most interfacial shear bonding strength was increased as increasing a composition of adding elements, and a heat-treatment time, and an oxygen partial pressure. From the results of this study it was found that the addition of alloying elements such as indium and tin increase hardness of as-cast alloy, produce surface oxide layer of adding elements by heat-treatment which may improve interfacial bonding strength between alloy and porcelain.

본 연구는 단면조사로 노인의 구강건강과 치매의 관계를 알아보고자 편의추출된 65세 이상 노인 197명을 대상으로 주관적 건강, 주관적 구강건강 및 관리, 핵심음식 저작능력, OHIP-14, KDSQ를 설문조사하고 구강검사를 실시하여 의치장착여부, 총 잔존치아수, 임플란트와 고정식보철물을 포함한 총 기능치아수를 조사하였다. 그 결과, KDSQ-C가 6점 이상인 치매검사 요구군에서 전신질환 유병률이 높았고, 주관적 건강상태에 부정적 응답 비율이 높았으며, 건강에 대한 염려가 많았고, KDSQ-V와 KDSQ-D도 유의하게 높았다. 정상군과 치매검사 요구군 간의 틀니장착자율, 총 잔존치아수, 총 기능치아수, 1일 칫솔질 횟수, 치아 통증 정도, 치주질환에 대한 주관적 증상정도, 주관적 구강건강상태, 주관적 구강건강염려의 차이는 없었다. 그러나, 치매검사 요구군이 주관적 치과치료 필요도가 높고 구강건강관련 삶의 질 제한정도가 높고 핵심음식 저작능력은 낮았으며 특히 딱딱한 음식군을 저작하기 어렵하고 하였다. KDSQ-C는 OHIP-14와 강한 양의 상관관계를 가지고 핵심음식 저작능력, 총 잔존치아수와는 약한 음의 관계를 가지고 있었다. 다중회귀분석에서는 KDSQ-D, KDSQ-V, OHIP-14 순으로 KDSQ-C에 영향을 미치는 것으로 나타났다. 따라서, 인지능력에 구강건강이 전신건강에 비해 미치는 영향력이 크지는 않지만 구강건강 또한 인지능력과 일부 관계할 수 있으며 인과관계를 분석하기 위해서는 더 정교한 역학연구가 필요할 것으로 제안한다.

One of the best way to prevent dental caries and periodontal disease is removing dental plaque. Toothbrushing is also one of the crucial ways to gel rid of dental plaque and improve dental hygiene. The purpose of th is study was to examine how many bacteria were attached to toothbrushes used by dental palque acidogenecity and related behaviors to toothbrush use. Subjects in this study were 30 college students in their twenties, on whom a survey was conducted to find out how they cleansed their toothbrushes, how long they cleaned toothbrushes after brushing, and how to keep them. And then dental palque acidogenecity by caries activity test was implemented and the number of bacteria attached to their toothbrushes was tested. The findings of the study were as follows : 1. Concerning correlations between dental palque acidogenecity and the number of remaining bacteria in the toothbrushes used by students, the number of bacteria was lower in the group of students with no caries activity than in the group with mild caries activity. 2. As for relations between the way of cleansing toothbrushes and the number of bacteria, there was no statistically significant gap between the group of students who wetted their toothbrushes with water and rubbed the heads of them and the group of students who just only wetted their toothbrushes with no further actions. 3. Regarding the relationship of toothbrush cleansing time to the number of bacteria, the number of bacteria was lower in the group of students who cleansed their toothbrushes for 15 seconds or more. 4. As to the influence of the number of toothbrush used by students, there was no significant difference between the group using just one toothbrush and the other group using two or more toothbrushes. 5. As for correlations between the way of keeping toothbrushes and the number of bacteria, no significant gap existed between the group thai kept their toothbrushes separately and the other that didn't.
