올해 또다시 6월 9일 치아의 날이 다가왔다. 지난 2월 전국을 떠들썩하게 만들었던 서울치대 교수 임용 비리사건의 악몽을 잊고 국민에게 더욱 가까이 다가갈 수 있는 기회를 맞은 셈이다. 해마다 개최되는 치아의 날 행사에 새로운 아이템의 개발이 필요하다는 목소리가 커지고 있는 시점에서 치아의 날의 역사와 문제점 그리고 개선방향에 대해서 살펴본다.

치아의 건강은 오복중의 하나라고 할 만큼 우리에게 소중한 신체기관이다. 치아가 건강하지 않다면 인생사의 즐거움 중의 하나인 '먹는 즐거움'을 누릴 수가 없다는 것은 부연의 여지가 없다. 그러나 갖가지 다양한 음식물과 여러 가지 질병들, 그리고 우리 자신의 소홀함 등으로 인해 치과질환을 앓는 사람들은 경제성장의 속도와 비례해서 날로 증가하고 있다. 예로부터 깨끗한 이, 고른 이는 미인의 조건이라고 얘기되어져 왔다. 이것은 타고 나는 복일 수도 있지만, 생활 속에서 조금이라도 더 관심을 가지고 관리해 나가는 것이 자신의 건강을 위해서도 좋겠고, 많은 사람들을 상대해야 하는 오늘날 사회생활의 예의이기도 할 것이다.

최근 우리나라 의료보험재정에서 구강진료비로 사용된 액수가 1990년에 1,869억원이었고, 1994년에 2,786억원, 1995년도에 3,507억원, 1998에는 5,986억원, 1999년에는 6,778억원으로 지난 10년간 계속 증가하는 양상을 보이고 있다. 그러나 치아우식증과 치주병으로 인하여 발거된 치아를 보철하는 비용은 이 치료비보다 훨씬 많을 것으로 추정되고 있어서 구강건강 관리비가 국민에게 부담이 되고 있을 것으로 추정된다. 과거부터 치아건강이 오복의 하나에 들 만큼 소중함에도 불구하고 여전히 치아우식증(충치)를 포함한 구강질환은 우리나라 사람의 다빈도 질환으로 자리 잡고 있다. 이달의 건강 길라잡이에서는 6월 9일 ‘치아의 날’에 즈음하여 일반적인 구강건강과 특히 청소년기 치아건강의 중요성을 새롭게 인식함으로써 외상으로부터 치아를 보호하여 평생 치아건강으로 적극적인 건강생활을 실천하는 계기를 마련하고자 한다.

The objectives were to evaluate the accuracy of shade selection by human visual system(VS) and 2 different colorimeters ($ShadeEye^{(R)}$(SE) and Shadepilot (SP)). Maxillary anterior teeth of 30 volunteers which had no caries or restorations were included in the study. Firstly, the accordance in shade selection by 3 dentists and 2 colorimeters was investigated. Secondly, the color of the teeth were measured by 1 observer's naked eye and 2 colorimeters under different illumination conditions (Sunny versus cloudy day). Additionally testing of inter-observer variability selected colors by 2 novice and 2 experienced dentists were compared. For comparing visual and 2 different colorimeters, SP(60%) showed significantly highest rate of accordance than the visual (23.3%) or SE (16.7%) and lowest mean ${\Delta}E$ ($2.62{\pm}0.74$ versus $3.83{\pm}1.38$;SE or $4.04{\pm}1.61$;VS)(p<0.001). If accuracy of shade selection were measured using VS, the mean ${\Delta}E$ value of cloudy day was higher than that of sunny day ($4.35{\pm}1.70$ versus $3.53{\pm}1.31$; p<0.001). There were no significant difference of the mean ${\Delta}E$ value between sunny and cloudy day in both SE and SP. Inter- observer repeatability was higher in 2 experienced group (73.3%) than novice group (36.7%). The mean ${\Delta}E$ of experienced group was lower than that of novice group ($3.60{\pm}1.47$ versus $4.70{\pm}1.67$; p<0.001). Colorimeters (SE or SP) is more accurate and more reproducible compared with human shade assessment. Using visual system may be limited by cloudy and inexperience of tester, then more experience and using colorimeters may be helpful of raising the accurate repeatability of shade selection.

This study was undertaken to investigate the relation between orthodontic force magnitude and the amount of tooth movement. And more light force application for reducing root resorption Twenty-four rats were divided into three experimental groups(A, B, C) based on force magnitude and application method. Springs of 50g force were applied to A group, springs of 100g force were applied to B group and springs of 25g force were applied to C group initially, and after 4 days springs of C group were changed to springs of 50g force. Two kinds of $sentally^{(R)}$(GAC U.S.A.) closed coil spring, 50g and 100g, were used. And we made 25g springs by heat treatment process of 50g springs. Each spring was inserted between the maxillary central incisor and the maxillary left first molar. Amounts of tooth movement were measured everyday by digital caliper($Digimatic^{(R)}$, Mitutoyo, Japan) under inhalation anesthesia for 15 days. After 15 days, all rats were sacrificed and histological samples were obtained with Hematoxyline-Eosin stain and Masson's trichrome stain. Following conclusion were made; 1. Group B showed the mean cumulative tooth movement of $2.19{\pm}0.41mm$ at 15th day, which was greatest among three groups, followed by group C($2.06{\pm}0.10mm$), group A($1.90{\pm}0.49mm$) respectively. however, there was no statistically difference among three groups. 2. All groups showed general tooth movement pattern and A, B, C group finished lag phase at 9th, 8th, 7th day, but there was no statistical significance. 3. Group A,B,C showed root resorption and especially group B showed the most severe root resorption and group C showed milder root resorption than other groups. According to the above results, large initial force with the development of a flirty widespread hyalinized zone may cause severe root resorption, so initial force should be applied lightly to reduce hyalinized area and eventually root resorption and then increased force will induce efficient tooth movement.

The purpose of this study was to explore some of the right directions for school dental-health education, by examining nursing students' knowledge on and attitude to the two major oral diseases in our country, dental caries and periodontal disease, as they will take charge of dental-health education and care for children in school dental-health center as sole expert health personnels after graduation. As a result of making an analysis of their knowledge and attitude, the following findings were acquired: (1) The students investigated perceived their oral cavity to tend to be healthy(36.8%) or in moderate situation(36.3%), although they had a subjective symptom for hot or cold food. (2) They thought dental caries is attributed to poor dental hygiene care(90.4%). Among them, 94.1% found toothbrushing effective for the prevention of dental caries, but just 40.2% agreed that toothbrush should be straight. (3) Those who considered fluoride effective for dental caries prevention thought the best way to use fluoride is taking fluoride-containing tap water(2.00). The second best way was fluoride mouth rinse(2.40), followed by the topical application of fluoride(2.70), use of fluoride dentifrice, and intake of fluoride(4.30) in the order named. (4) The regular examination and toothbrushing were mentioned as a way to prevent dental caries, but just toothbrushing was put in action for dental health. So their knowledge and actual attitude weren't the same. (5) They brushed their teeth for oral health(94.3%). Toothbrushing was done after breakfast(71.9%) or before bedtime(65.8%). Just 40.3% performed toothbrushing after lunch. That was implemented twice(35.7%) or three times(37.6%) a day. (6) Out of those who pointed out toothbrushing as a way to prevent periodontal diseases(84.7%), the effect of toothbrushing on the prevention of periodontitis wasn't supported by 7.1% of those who completed the course of study for the teaching profession and by 17.0% of the others who didn't. The two groups weren't of the same opinion. The above-mentioned findings suggest that the dental knowledge of the nursing students wasn't good enough to be properly responsible for school children's dental health care. In particular, there was a gap between knowledge and attitude. To improve children's poor dental health and help their oral cavity stay healthy, there is a need to activate school dental-health center, which is now in model operation, and to make the most of dental hygienists, who are educated to be a dental-health specialist, for more successful dental-health care for school children.
