Excessive tooth wear causes loss of tooth structure, disharmony of occlusal plane, functional and esthetic problems. Although the decrease of occlusal vertical dimension may be compensated by growth of alveolar bone, if the length of tooth is not enough for the retention of restoration, minimum increase of occlusal vertical dimension is required without discomfort of the patient. In this case, 33-year-old woman drinks more than 1 liter of soft drinks a day and has bruxism in night time, visited in Seoul National University Dental Hospital with chief complaint of generalized tooth wear and related esthetic and functional problems. It was considered as a loss of occlusal vertical dimension based on the accelerated tooth wear caused by erosion and bruxism and facial appearance, phonetic, esthetic, functional evaluations. It was planned to raise occlusal vertical dimension by provisional restoration two times for patient's adaptation, 3 mm and 2 mm each, total 5 mm. Confirming no discomfort and clinical symptom during total 16 weeks after restoration with provisional fixed restoration, it was restored with porcelain fused to gold crown and bridge. Because the patient was young woman, anterior teeth were restored with collarless porcelain fused to gold crown. This case presents that satisfactory esthetic and functional result by full mouth rehabilitation with increase of occlusal vertical dimension.

The purpose of this study was to obtain information on the clinical and radiographic features of the fibro-osseous lesions in the jaws. For this study, the author examined and analysed the clinical records and radiographs of 71 cases of 68 patients in fibrous dysplasia, 35 cases of ossifying fibroma and 30 cases of 16 patients of periapical cemental dysplasia diagnosed by clinical and radiographic or histopathological examinations. The obtained results were as followings: L Fibrous dysplasia occurred most frequently in the 2nd decade (30.0％), ossifying fibroma in the 3rd-4th decades, periapical cemental dysplasia in the 4th decade, and all of three lesions showed slight predilection in females. In most cases, chief complaints were painless facial swelling in fibrous dysplasia and ossifying fibroma, and periapical cemental dysplasia was found accidentally in radiographs. 2. Fibrous dysplasia was occurred more frequently in maxilla, ossifying fibroma in mandible and both lesions in premolar-molar area. Periapical cemental dysplasia was occurred most frequently in the mandibular anterior area. The size of fibrous dysplasia was larger than that of ossifying fibroma, and the shape of ossifying fibroma was more round and elliptical than fibrous dysplasia whose was fusiform. 3. Fibrous dysplasia was shown homogeneous radiopaque shadow of 57.6％ and ossifying fibroma & periapical cemental dysplasia were shown mixed appearance of radiolucency and radiopacity shadows at 74.2％, 60.0％, respectively. 4. Fibrous dysplasia was entirely shown poorly defined at 87.7％, but ossifying fibroma & periapical cemental dysplasia were shown well outlined at 60.0％, 70.0％, respectively. 5. Cortical thinning and expansion were observed in fibrous dysplasia and ossifying fibroma, and severe in ossifying fibroma than fibrous dysplasia, and those signs were not seen in periapical cemental dysplasia. Loss of lamina dura was dominant in fibrous dysplasia and root resorption was dominant in ossifying fibroma. Displacement of mandibular canal and the degree of the increase of vertical dimension were alike in both lesions. Displacement of maxillary sinus or nasal cavity, thinning & expansion of the maxillary sinus were dominant in fibrous dysplasia. 6. Polyostotic fibrous dysplasia was occurred at 5.9％, Multiple periapical cemental dysplasia at 43.7％. Occurrence rate in the edentulous area of fibrous dysplasia and ossifying fibroma were 7.0％, 8.6％, respectively.

Purpose : Kabuki syndrome is a multiple congenital malformation syndrome with mental retardation. It was named after its characteristic appearance, a face resembling that of an actor in a Kabuki play. To date, six Korean cases of Kabuki syndrome have ever been reported. Here, we present the phenotypic and genetic characteristics of six patients with Kabuki syndrome. Materials and Methods : Between 2003 and 2009, six Korean girls have been diagnosed and followed up as Kabuki syndrome at Center for Genetic Diseases of Ajou University Hospital. Their clinical and laboratory data were collected and analyzed by the retrospective review of medical records. Results : All six patients showed the characteristic facial dysmorphism and developmental delay. Persistent fingertip pads were also found in all patients. Most patients showed postnatal growth retardation (83.3%) and hypotonia (83.3%). Opthalmologic problems were common, particularly for strabismus (83.3%). Congenital heart defects were present in three patients (50%). Skeletal abnormalities including 5th finger shortening (83.3%), clinodactyly (50%), joint hypermobility (50%) and hip dislocation (16.7%) were also observed. There was no patient who had positive family history for Kabuki syndrome. Cytogenetic and molecular cytogenetic analyses including karyotyping and array CGH could not reveal any underlying genetic cause of Kabuki syndrome. Conclusion : Korean patients with Kabuki syndrome showed a broad spectrum of clinical features affecting multiple organ systems. Although clinical manifestations of Kabuki syndrome have been well established, our results failed to detect recurrent chromosome aberrations which could cause Kabuki syndrome. Its natural history and genetic background remains to be further studied for providing appropriate management and genetic counseling.

Orthognathic surgery of skeletal Class III malocclusion improves oral function and facial appearance. The greater amount of skeletal discrepancy, the greater amount of teeth movement required for decompensation, and this often causes pathological changes in periodontal tissue especially in lower anterior dentition. We made a Top-Down treatment plan with personalized analysis using Face Hunter, Plane System and ARCUS Digma II, in order to resolve severe mobility and cross-bite of lower anterior teeth for 49-year-old female patient who had undergone orthognathic surgery 20 years ago due to skeletal Class III malocclusion and mandibular prognathism. Lower anterior teeth were extracted and alveoloplasty was done. After healing of the wound, immediate loading was conducted immediately after implant placement. Final restorations were fabricated Zirconia using CAD/CAM, and inserted intraorally screw-retained type. During 6-month follow-up, no abnormal episodes of restorations were observed, and obtained satisfactorily both of functional and esthetic outcomes.

In order to manufacture functional and esthetic prostheses, it is essential to accurately transmit information about the patient's occlusal plane. In particular, in the case of a completely edentulous patient, the occlusal plane is very important to correctly support the soft tissue, to achieve aesthetic harmony with the facial appearance, and to properly pronounce it, and to form a balanced occlusal relationship for stable mastication. In the conventional method, various facebow systems were used to transmit patient's information from the clinic to the laboratory, but there were several limitations in the process of transferring them to CAD. To simplify this process, a prefabricated POP (PNUD Occlusal Plane) Bow system was recently developed. In this case, a CAD-CAM (Computer-aided design-computer-aided manufacturing) treatment dentures reflecting the patient's occlusal plane information was manufactured using the POP Bow system during the treatment of a completely edentulous patient, and aesthetic and functional satisfaction was obtained.

The aim of this study was to propose Rosa multiflora (R. multiflora) as a cosmetic material for refining pores, and the ethanolic extract of R. multiflora (RME) was used to identify changes in various factors related to sebum regulation, astringency, and extracellular matrix, which are known to affect pores, and the effects were confirmed through clinical trials. The effects of these changes were confirmed through clinical trials. As a result, RME suppresses the excessive production of sebum, and it possesses DPPH radical scavenging ability through an astringent tannin component. Futhermore, RME inhibited 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) activity and matrix metalloproteinase-1 (MMP-1) production, and it increased hyaluronic acid synthesis. In clinical trials, it was confirmed that RME significantly reduced the area, depth, number, volume, and density of pores-key parameters for assessing pores-and it also reduced sebum levels. This suggests that RME has an astringent effect and could be used as a cosmetic ingredient to improve the appearance of pores by controlling sebum production and influencing ECM-related factors.

Multi-modal generation is the process of generating results based on a variety of information, such as text, images, and audio. With the rapid development of AI technology, there is a growing number of multi-modal based systems that synthesize different types of data to produce results. In this paper, we present an AI system that uses speech and text recognition to describe a person and generate a montage image. While the existing montage generation technology is based on the appearance of Westerners, the montage generation system developed in this paper learns a model based on Korean facial features. Therefore, it is possible to create more accurate and effective Korean montage images based on multi-modal voice and text specific to Korean. Since the developed montage generation app can be utilized as a draft montage, it can dramatically reduce the manual labor of existing montage production personnel. For this purpose, we utilized persona-based virtual person montage data provided by the AI-Hub of the National Information Society Agency. AI-Hub is an AI integration platform aimed at providing a one-stop service by building artificial intelligence learning data necessary for the development of AI technology and services. The image generation system was implemented using VQGAN, a deep learning model used to generate high-resolution images, and the KoDALLE model, a Korean-based image generation model. It can be confirmed that the learned AI model creates a montage image of a face that is very similar to what was described using voice and text. To verify the practicality of the developed montage generation app, 10 testers used it and more than 70% responded that they were satisfied. The montage generator can be used in various fields, such as criminal detection, to describe and image facial features.

In parallel with social and economic progress, motives of patients to consult dentists have increased and diversified. An increasing number of people visit dental clinics to improve their facial appearance and masticating functions deteriorated largely due to malocclusion. There is also greater interest in and concern as well as demand for teeth alignment treatment among people. Under this situation, it is required to find and suggest ways to enhance quality and profitability of dental care in view of managerial needs for dentists to cope with changing circumstances. This study, thus, aims to measure satisfactions of orthodontics patients and to determine the elements influencing their satisfactions. For this aim, a survey was performed for 20 days from March 7th to 26th, 2005 by means of questionnaires distributed to randomly selected samples, resulting in following conclusions: 1. From comparison of satisfactions with dental service by their elements, higher satisfaction was reported from orthodontics patients in the element of dental hygienists(4.21). Least satisfaction, however, was found in the procedure for treatment and waiting hours(3.73). 2. By gender, male orthodontics patients turned out to be more satisfactory with dental service than females. In terms of intention for return visits, both male and female orthodontics patients showed higher satisfaction than non-orthodontics ones. 3. As for satisfaction with dental service by age of orthodontics and non-orthodontics patients, with regard to intention for return visit, orthodontics patients of all ages showed to have higher grade of satisfaction. 4. Regarding satisfaction with dental treatment by orthodontics and non-orthodontics patients by monthly income, Dental hygienist with intention for return visit, the higher the satisfaction of orthodontics patients. 5. In regard to satisfaction with dental treatment by education, higher satisfaction was expressed by orthodontics patients with elementary school education kept dentist, dental hygienist and internal and external environments. As a result from this study, we knew that dental service of the orthodontics patients is higher satisfaction than that of the non-orthodontics patients.
