With an increase of public"s perception on “minimally invasive dentistry”, more patients are demanding orthodontic alignment of anterior teeth rather than restorative treatment which is more invasive. One draw back of orthodontic alignment has been that it takes long time. To overcome this limitation, a new orthodontic device named Mini-Tube Appliance (MTA), have been developed. With the combined use of light NiTi wire and inter-proximal stripping, rapid anterior alignment can be obtained efficiently. This article presents the use of MTA for rapid alignment of anterior teeth and its clinical guidelines with typical case samples.

김석필,김년경,이현정,황현식 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.5

본 연구는 폴리카보네이트 브라켓 부착 시 표면처리가 결합강도를 증진시키는지 알아보고자 시행되었다. 소의 하악 중절치를 포매하여 만든 100개의 시편에 광중합형 레진 접착제를 이용하여 폴리카보네이트 브라켓(Alice, 광명 데이콤, 대한민국)을 부착하였다. 대조군의 경우, 표면처리 없이 부착한 반면, 실험군의 경우 샌드블라스팅 처리한 경우, plastic conditioner 처리하여 부착한 경우, 그리고 샌드블라스팅과 함께 plastic conditioner 처리한 경우로 구분하여 접착하였다. 만능시험기를 이용하여 전단결합강도를 측정하고 파절양상을 비교 분석한 결과, plastic conditioner나 샌드블라스팅으로 표면처리를 시행한 경우 표면처리를 시행하지 않은 경우에 비해 높은 결합강도를 보였다 (p<0.001). 샌드블라스팅과 Plastic conditioner를 모두 처리한 경우는 샌드블라스팅만이나 plastic conditioner만 처리한 경우보다 높은 결합강도를 보였으며, 특히 샌드블라스팅만 처리한 경우에 비해서는 통계적 유의차를 보였다 (p<0.05). 이상의 연구결과는 폴리카보네이트 브라켓 부착 시 결합강도 증진을 위해서 베이스의 표면처리가 필요하며 샌드블라스팅 후 plastic conditioner 도포가 가장 효과적임을 보여주었다. Objective: The purpose of this study was to evaluate whether the bond strength of polycarbonate brackets can be increased through surface treatment. Methods: One hundred polycarbonate brackets (Alice) were bonded to bovine incisors with light-cured adhesive. The bracket bases were treated with one of three methods; sandblasting, plastic conditioner application, and combined treatment with sandblasting and plastic conditioner. The brackets without any surface treatment served as the control. The shear bond strength was tested with a universal testing machine, and failure pattern was assessed with the adhesive remnant index. Results: The shear bond strength in all experimental groups was higher than that of the control group (p<0.001). The group treated with plastic conditioner after sandblasting showed statistically higher shear bond strength than the sandblasting only group (p<0.05). The group treated with plastic conditioner after sandblasting showed higher shear bond strength than plastic conditioner only group, but the difference was not statistically significant. Conclusion: The above results suggest that the surface treatments of polycarbonate bracket is mandatory to improve bond strength, and the most effective method is an application of plastic conditioner after sandblasting.

김석필,황인남,조진형,황현식 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.2

본 연구는 교정용 브라켓 부착을 위한 레진 접착부위 및 그 인접부위 즉, primer만 도포된 부위의 색변화를 알아보기 위하여 시행되었다. 교정치료를 위해 발치된 60개의 건전한 소구치를 재료로 사용하여 분광측정기로 색을 측정한 후 CIE L*a*b* 색표계로 기록하였다. 20개의 소구치에 광중합형 접착레진으로 브라켓을 부착한 후 부착 전과 제거 후의 색을 측정하였으며 다른 20개의 소구치에는 primer만 도포하고 도포 전과 도포 후의 색을 측정한 후, L* 값을 이용하여 명암 변화를 살펴본 결과 브라켓 부착 및 primer 도포 모두의 경우 명도가 감소하는 경향을 보였으며, a* 값과 b* 값을 이용하여 색상 변화를 살펴본 결과 황색이 증가하는 양상을 나타내었다. 또한 측정된 L*a*b* 값을 이용하여 색변화를 산출하고 임상적으로 인지할 수 있는 색변화 값 3.7을 기준치로 하여 비교 및 분석을 시행한 결과 브라켓 부착 전과 제거 후의 색변화는 기준치보다 큰 것으로 나타났으며 primer 도포에 따른 색변화는 기준치보다 크지 않은 것으로 나타났다. 한편 primer만 도포한 경우 칫솔질에 따른 색변화를 알아보고자 나머지 20개의 소구치를 대조로 하여 칫솔질을 시행한 결과 칫솔질 시행 후 색변화는 기준치보다 큰 것으로 나타났다. 브라켓 제거 후 자연광 노출의 영향을 알아보기 위하여 모든 경우에 추가적으로 photoaging을 시행한 결과 부기적인 색변화는 기준치보다 작은 것으로 나타났다. 이상의 결과는 교정치료를 위한 브라켓 부착으로 인해 브라켓 부착 및 인접부위의 치아색 변화가 있음을 의미하며 임상과정에서 이에 대한 고려가 필요함을 시사하였다. The purpose of this study was to evaluate the tooth color changes of resin bonding sites and their adjacent sites on orthodontic bracket bonding. Sixty extracted sound premolars were used and the tooth color was recorded according to the CIE L*a*b* color system using a spectrophotometer. The tooth colors of the twenty premolars were measured and compared before bracket bonding and after removal. On a further twenty premolars, the tooth color was measured before and after only primer application. In the change of L* values, according to the bracket bonding and primer application, the lightness was decreased, and in the change of a* and b* values, the color was changed into a more yellowish color. The color differences (ΔE*) were calculated from the L*a*b* values and compared with the standard value of clinical detection (ΔE*=3.7). The color differences between before the bracket bonding and after removal noted exceeded the standard value and those of between before and after the primer application were not larger than the standard value. Tooth brushing was performed after application of the primer to evaluate the color changes according to the primer abrasion. As a control, toothbrushing was performed on the last twenty premolars. The color differences noted were larger than the standard value after toothbrushing. Also, to evaluate the color changes of the tooth which is exposed to sun irradiation after bracket removal, additional photoaging was performed and the color was measured for all teeth. The additional color differences after photoaging were smaller than the standard value. The above results suggest that the tooth color changes after fixed orthodontic treatment.

As to the treatment of peptic ulcer, this study was made to compare the clinical effectiveness between ranitidine and cimetidine which are compounded H₂-receptor antagonist. Patients were examined regularly to insure clinical effectiveness with a total of 75 cases of peptic ulcer(gastric ulcer 32 cases, duodenal 43 cases) They were diagnosed to have peptic ulcer by gastroduodenoscopy at the endoscopic room of Seoul Red-Cross Hospital, during 2 years from January 1984 to December 1985. Our study divided the patients into two groups, one with gastric ulcer and the other with duodenal ulcer. At random, these groups were divided into two more groups. One of these random groups was treated, with cimetidine, the other with ranitidine. To the cimetidine group, cimetidine was given in a dosage of 1,000-mg orally a day (200-mg three times and 400-mg at bedtime), and to the ranitidine group, ranitidine was given in a dosage of 150-mg orally twice a day. Thus, our results were obtained. Those in our studies were observed after treatment of four weeks, six weeks, and eight weeks by gastroduodenoscopy. 1) The male to female ratio of gastric ulcer was about 5.4 : 1, duodenal ulcer was about 3.3: l. So, males were predominent in both ulcers, and the most prevalent age group was those in their fifth decade of life having gastric ulcer, fourth decade of life having gastric ulcer, fourth decade of life in duodenal ulcer. 2) The location of the gastric ulcers were 15 cases in angle, 10 cases in antrum, and 7 cases in body. For duodenal ulcer were 36 cases in bulb, and 7 cases in pyloric area. 3) As to the subjective symptoms caused by gastric ulcers, the order was epigastric pain, hunger pain, abdominal bloating sensation, nausea and vomiting, and dyspepsia. These were also the same symptoms in duodenal ulcer. The improvement of symptoms were in the same or1er on both sides. The symptoms were relieved after 1 week of treatment in 66 777.2% of the cases, after 2 weeks of treatment in 82,486.6% of the cases, after 4 weeks of treatment in all cases. 4) The cumulative rates of complete healing of the ranitidine group having gastric ulcer goes as follows. Out of 15 subjects, 73%(11 cases) were healed after 4 weeks, 86%'(12 cases) were after 6 weeks and all were completely relieved after 8 weeks of treatment. Those of the cimeditine group consisted of 17 subjects, 65%(11 cases) were healed after 4 weeks, 80%(12 cases) after 6 weeks, 93%(13 cases) were relieved after 8 weeks of treatment. Those of the ranitidine group having duodenal ulcer consisted of about 21 subjects, 81%(17 cases) were healed after 4 weeks, 90%(18 cases) after 6 weeks of treatment. Those of the cimetidine group about 22 subjects, 68% (15cases) were healed after 4 weeks, 89% (16 cases) after 6 weeks and all were completely relieved after 8 weeks of treatment. 5) The untoward side effects were not founded in the use of these drugs except for 2 cases of the cimetidine group. The side effects were dizziness, headache and nausea. No abnormal findings were observed in the physical examination and in laboratory data. Finally, the conclusion of the above-stated is that ranitidine was considered an effective and a safe drug in the treatment of peptic ulcer disease the same cimetidine.
