A depressed alvelolar ridge and a collapsed interdental papilla in the anterior region may interfere with esthetic prosthodontic repair. The resultant sequelas will cause overcontoured prosthesis or dark shadow under pontic which may not suffice our patients' esthetic demands. So, surgical periodontal treatment has been needed for esthetic repair in deformed ridges and extensive interproximal spacing. Our treatment option alters Dr.Abram's roll technique to make palatally extended connective tissue secondary pedicle flap to obtain additonal connective tissue. Blood supply maintenance, least trauma, and no secondary wound is advantages in this modification.

Recently, according to the concept of minimal invasive, there have been many opportunities for restoration treatment with porcelain laminate veneers that are less invasive and can ideally improve esthetics. Patients also visit the laminate well, and patients also want to reduce the amount of teeth cut, so the choice of the entire trimming crown is decreasing. Therefore, various techniques of laminate are required. Most dental clinicians seem to have negative images of laminates such as risk of fracture, margin pigmentation and dropout. However, this situation is due to incorrect adhesion manipulation and lack of inspection of the occlusal relationship, and there is no problem with the Porcelain Laminate Veneer itself. The purpose and scope of adaptation leading to the success of porcelain laminate veneer will be introduced.

Diastema often does not cause functional problems, but it is not without aesthetic issues. It is considered a serious aesthetic flaw by many patients. Traditional orthodontic and prosthetic treatments have been the mainstream treatment, but there has been an increasing demand for treatment using composite resin. Even though anterior teeth are relatively easy to access and have good visibility, many dentists do not prefer resin-based treatments because they are more complicated and time-consuming than expected. In this article, we will examine four techniques for addressing diastema and discuss their advantages and disadvantages.

Not to recreate the final prosthesis is the shortest way to get a successful outcome. In the case of an aesthetic prosthesis, it is important not only the condition of the oral cavity but also the whole harmony in the face such as the interpupillary line and the smile line. But the dental technician creates the prosthesis only based on the oral model. So if you want to prevent the failure of the prosthesis due to discordance with the face, it is a good idea to use patient's facial photography and provisional restorations to reproduce facial features, shapes and aesthetics before switching to a final prosthesis. To prevent the failure of the final prosthesis, it is important to communicate among the patient, the technician and the doctor according to the model diagnosis, facial and oral photos. Then all the technicians will get satisfactory results. In addition, the technician have to understand the form of natural teeth, to analyze and reproduce colors, and to understand materials in order to produce a successful aesthetic prosthesis. From now on, I will explain two parts. At first, the communication in the dental office for the successful production of aesthetic prosthesis through the clinical case. And the second, my opinion for the successful aesthetic prosthesis.

The author treated 3 class I malocclusion patients with the lingual appliance followed by the extraction of the 4 bicuspids. One of them was finished with the labial appliance at the final stage. The treatment results were acceptable and the patients had good tolerance to the lingual appliance without complaints in these cases. There were some problems in treatment on the lingual side both the patient and the practioner, but I think we can overcome them with the development of the orthodontic materials, the treatment technics & the increased clinical experience. Of course, we cannot treat all the patients with the lingual braces, but patients are carefully selected, lingual braces will be a valuable orthodontic appliance. In conclusion, the lingual braces have very good esthetic advantages, so the patients, especially in adults, who hesitate or refuse the orthodontic treatment due to the esthetic problem of the labial braces will get the motivation & the chance for the orthodontic treatment.

Often there are edentulous patients with severe vertical resorption of the alveolar ridge so that implant placement in the mandibular posterior is impossible. In this case, implants can be placed in the anterior portion of the mandible and the patient can be treated with an implant assisted overdenture, but the inherent discomfort of the removable prosthesis can not be overcome. However, if implants are appropriately placed between the mental foramen of both sides and a fixed hybrid prosthesis is fabricated to the patient, the patient will be satisfied without the inconvenience of the removable prosthesis. However, the treatment plan should be well designed to prevent disadvantages and expected complications of fixed hybrid prosthesis. Based on my clinical experience, I will explain treatment plan and protocol in detail.

This research is intended to study the dietary experiences by college women to promote women's health through the proper diet. The approach method was used grounded theory. The participants were selected 3 colleges in Seoul, Inchon, and Cheongju. The selected 15 women were college students who had a history of dietary experiences or who were on the way of diet at the time of the start of this research. The data were collected from August 2001 to October 2001. Data collecting method was a Focus Group Interview. The data were analysed by the Strauss and Corbin's method(1966). The results were showed that the 236 concepts in the dietary experiences were gathered into 48 sub-categories, eventually being integrated into 17 higher categories. 'Esthetic self-pursuit' is the core phenomenon of the dietary experiences. Such phenomenon is due to subjects physical problems, sense of comparison and desire of weight-loss. In the circumstantial context, the esthetic self-pursuit phenomenon is enhanced by social opinions, aesthetic senses, and the recognition of self-control. The interaction strategy of the esthetic self-pursuit can be intensified and sustained by will power, supporting systems, and accessibility. Through the dietary experiences, the body changes positive or negative figures. Following the sense of success or failure, the diet are sustained or abandoned accordingly. Therefore for the application of promoting health, an intervention strategy should be created a collect organized diet program in a social level not a private level.

Objective: In our previous study, glass-fiber-reinforced plastics (GFRPs) made from polycarbonate and glass fibers were prepared for esthetic orthodontic wires using pultrusion. These laboratory GFRP wires are more transparent than the commercially available nickel-titanium wire; however, an investigation of the color stability of GFRP during orthodontic treatment is needed. Accordingly, in the present study, the color stability of GFRP was assessed using colorimetry. Methods: Preparation of GFRP esthetic round wires (diameter: 0.45 mm [0.018 inch]) using pultrusion was described previously. Here, to investigate how the diameter of fiber reinforcement affects color stability, GFRPs were prepared by incorporating either $13-{\mu}m$ (GFRP-13) or $7-{\mu}m$ glass (GFRP-7) fibers. The color changes of GFRPs after 24 h, and following 1, 2, and 4 weeks of coffee immersion at $37^{\circ}C$, were measured by colorimetry. We evaluated the color stability of GFRPs by two evaluating units: the color difference (${\Delta}E^*$) and National Bureau of Standards (NBS). Results: After immersion, both GFRPs showed almost no visible color change. According to the colorimetry measurements, the ${\Delta}E^*$ values of GFRP-13 and GFRP-7 were 0.73-1.16, and 0.62-1.10, respectively. In accordance with NBS units, both GFRPs showed "slight" color changes. As a result, there were no significant differences in the ${\Delta}E^*$ values or NBS units for GFRP-13 or GFRP-7. Moreover, for both GFRPs, no significant differences were observed in any of the immersion periods. Conclusions: Our findings suggest that the GFRPs will maintain high color stability during orthodontic treatment, and are an attractive prospect as esthetic orthodontic wires.

Direct bonded restoration with composite resin is one of the few areas which the achievement and result are available in chair side. Especially free-hand bonding technique and incremental technique give us challengeable opportunity for restoring severely damaged anterior teeth. If clinicians have keen sense of observation to evaluate polychromatic characteristics of natural teeth, hue, chroma, value, translucency, opacity and correlate the observation result with various kinds of composite resins, they will have privilege to share joy from restoring damaged anterior teeth in chair side immediately.

Root coverage can be an efficacious treatment not only in aspect of dental symptoms like root caries and hypersensitivity, but also in aspect of esthetic problem. There are several predictable methods for gaining a connective tissue attachment to an exposed root surface. Among them, this case report will deal with three cases using enamel matrix derivative and connective tissue graft to recover esthetic and physiological periodontal environment and its form. This case report deals with three patients with gingival recession which has occurred by different causes. They were treated with de-epithelialized graft accompanied by application of enamel matrix derivative. 6-12 months later, all three patients showed considerable root coverage and clinically stable condition of healing. In conclusion, within the limitation of this study, de-epithelialized connective tissue graft accompanied by application of enamel matrix derivative shows stable and clinical acceptable results in aspect of root coverage.
