General anesthesia (GA) for dental care in handicapped patients is necessary to facilitate the provision of safe, efficient, and effective quality treatment. The aims of this study were to determine the anesthetic characteristics of handicapped patients in need of dental treatment in these day care units, and to establish for plan to provide better services. 325 patients who had outpatient general anesthesia from January 2005 to March 2014 were assessed for this study. Patients' distribution and treatment patterns were examined. The proportion of male patients (202, 62.2%) was higher than female patients (123, 37.8%) and the largest group of patients were 5 to 10 years old (85, 26.2%). The reasons for general anesthesia included mental and physical disabilities (207, 63.7%), behavior management (84, 25.8%), parent needs (14, 4.3%), and so on. Restorative treatment was the most common procedure with the average of 4.2 teeth treated per one patient and 43 (13.2%) patients underwent general anesthesia for dental treatment more than once. To expand and improve access to the dental care of the disabled, improvement of the health care system, enhancement of their training for dental care by professionals, and enlarging caregivers'understanding of the importance of oral care in the early stages are required.

Maxillary median diastema is the term used when there is spacing between maxillary central incisors. The space between maxillary central incisors are often observed during ugly duckling stage. In most of the cases, as maxillary permanent canines erupt, it gradually disappears. Maxillary median diastema needs to be treated when there is up to 2mm of space between the incisors even after eruption of permanent canines or when there is 3mm of space, at least, before the eruption of the canines. Particulary, for the latter case, orthodontic treatment is recommended because not only the esthetic point of view but also to regain the eruption space for maxillary lateral incisors and canines. The appliance used for orthodontic treatment are removable appliances, using finger spring and etc, and fixed appliances, using rubber elastics and coil spring. If rubber band alone was used to treat median diastema without any other appliance such as band, tube or bracket, it will gradually move downward along the root surface. Then it will destroy the peridontal ligament and causes tooth mobility, extrusion, and avulsion. This report presents cases of damaged tooth due to improper use of rubber band when treating maxillary median diastema.

Objectives: The aim of this study was to analyze the accessibility of dental care services among individuals with precarious employment in South Korea. Methods: We used the $9^{th}$ wave of the Korean Health Panel data (2015) and included 7,736 wage and non-wage earners in our study. We determined precariousness in the labor market as a combination of employment relationship and job income, and categorized individuals based on this into the following four groups: Group A comprising those who report job and income security, Group B comprising those who experience job insecurity alone, Group C comprising those who report a stable job but low income, and Group D comprising those who experience both job and income insecurity. Accessibility to dental care services was determined by experience of unmet dental care needs and unmet dental care needs caused primarily by financial burden. Logistic regression analyses were used to assess the effect of precarious work on access to dental care services. Results: Individuals with job insecurity (Group B; OR=1.445; 95% CI=1.22-1.70) and both job and income insecurity (Group D; OR=1.899; 95% CI=1.61-2.24) were more likely to have unmet needs than the comparison group. Both groups B and D were also 2.048 (95% CI=1.57-2.66) times and 4.435 (95% CI =3.46-5.68) times more likely, respectively, to have unmet dental care needs caused by financial burden. Education status, health insurance, and health status were all also effective factors influencing unmet dental care needs. Conclusions: Unstable employment and low income resulted in diminished access to dental care services. Therefore, governments should consider health policy solutions to reduce barriers preventing individuals with employment and income instability from accessing adequate dental care.

The aim of this study was to clarify the barriers of dental treatment for special needs patients felt by dentists and to determine the dentist-related factors contributing to the obstacles in treatment planning and decision making. Questionnaires were distributed and responded by dentists working at five public-based special care clinics in South Korea. Factors divided into three parts (dentist demographics, clinical factors, and educational and administrational factors) were assessed and analyzed for correlations between dentist-related factors and dentist-felt burdens for special care treatment. Fisher's exact test and Chi-square test were used at the level of 0.05. A total of 34 dentists responded to the questionnaires. Almost all dentists had obstacles in the treatment of special needs patients in terms of the patients' lack of cooperation (94.1%), proxy communication with caregivers (94.1%), payment reward system (63.6%), deficient workforce (67.7%), and others. The longer dentists had been practicing for special needs patients, the more they were dissatisfied with the reward system and a longer time was spent for communication with patients and their caregivers (p<0.05). For specialists, more obstacles were experienced in treatment planning due to a deficiency in the clinical information obtained from their patients compared to general practitioners (p<0.05). A total of 82.4% of the respondents approved of mandatory educational programs for special care dentists. There were practitioner-based factors related to the amount of obstacles felt by special care dentists. To overcome the treatment barrier of special needs patients, in-depth education and training are required in special care dentistry.

This article discusses the provision of sedation for uncooperative special need dental patients. Most of dental treatments have been performed in these patients with the techniques of behavioral control. However, if this behavioral control fails during treatment, it is nearly impossible to treat them without either sedation or general anesthesia. Sedation is also beneficial for patients because it circumvent the aggravation of negative behaviors related to their stress during the treatment. Also, the morbidity and mortality related to dental sedation is relatively low. In this regard, the provision of sedation for people with special needs can be considered as a safe and necessary techniques for their treatment.

In everyday dental practice, one of the most important procedures is fixed prosthodontics which includes gold and ceramic restorative treatments. This procedure can be divided into tooth preparation, impression taking, laboratory work, occlusal adjustment and cementation. The first step is tooth preparation and it needs not only good techniques but also deep knowledge and understanding of oral biology. Also, there must be good knowledge of the principles and materials of the procedure. The patient's satisfaction can be achieved from natural contour, good shade, and precise margin fit, especially in ceramic restorations on anterior regions. It is essential to fastidiously prepare the tooth to make aesthetic restorations with a good margin fit. Tooth preparation techniques and three case reports of ceramic restorations on the anterior region are presented and discussed in this paper.

Purpose : The purpose of this study was to investigate whether the fractal dimension of successive panoramic radiographs of bone after implant placement is useful in the characterization of structural change in alveolar bone. Materials and Methods. Twelve subjects with thirty-five implants were retrospectively followed-up from one week to six months after implantation. Thirty-six panoramic radiographs from twelve patients were classified into 1 week, 1-2 months and 3-6 months after implantation and digitized. The windows of bone apical and mesial or distal to the implant were defined as periapical region of interest (ROI) and interdental ROI; the fractal dimension of the image was calculated. Results There was not a statistically significant difference in fractal dimensions during the period up to 6 months after implantation. The fractal dimensions were higher in 13 and 15mm than 10 and 11.5mm implant length at interdental ROIs in 3-6 months after implantation (P<0.01). Conclusion : Longer fixtures showed the higher fractal dimension of bone around implant. This investigation needs further exploration with large numbers of implants for longer follow-up periods.

With the understanding of tooth crown biomechanics and the progress of dentin adhesives, bonded porcelain restorations including a porcelain laminate veneer present an extended spectrum of indications for anterior teeth. Porcelain laminate veneer as a restoration offers the conservative solution that balances the functional and esthetic needs of the anterior dentition. Porcelain's stiffness, its surface characteristics, and the biomechanical strength achieved through bonding to tooth surface enable the restoration of the tooth as a whole supporting occlusal force and masticatory function. Namely, the optical effects inherent in the tooth and the lifelike features of the porcelain make that this restoration approaches the ultimate in esthetic satisfaction for both the dentist and the patient. A 49-year-old female patient with the incisal discoloration of upper central incisors and black triangle between the central incisors was referred to correct her esthetic problems with prosthodontic approach. The patient was satisfied with two porcelain laminate veneers that were made according to prof. Magne and Belser's recommendation.

There are many kinds of maintenance care services for removable denture patient. Adjustment of the denture base and occlusion should be performed regularly not only for pain relief but also for maintaining the denture function. Direct and indirect relining are needed frequently in specific cases including mandibular distal extension case or non-symmetric residual teeth situation. Surface treatments for metal and resin are essential in the relining procedure. Clinical process for the denture repair is similar to indirect relining which needs inter-occlusal registration. Especially, the peridontal maintenance care and caries prevention are most important way to preserve the abutment teeth in partial edentulism. Moreover, the caring method for the denture and the tissue should be instructed to the denture patient.

Objectives: This study was conducted to investigate the effect of self-control and interpersonal relationship satisfaction on department satisfaction among dental hygiene students. Methods: A survey was conducted on 306 dental hygiene students from Seoul, Gyeonggi, Chungcheong, Jeolla, and Gyeongsang. Results: The factors affecting college department satisfaction of dental hygiene students were interpersonal relationship satisfaction (β=0.609), volunteer activities_dummy 1 (No/Yes) (β=0.131), and year_dummy 3 (1/4) (β=0.128). The most deterministic factor was interpersonal relationship satisfaction with the explanatory power of 37%. Conclusions: Based on these results, it is thought that research on department satisfaction needs to be actively conducted to develop adequate measures and programs to enhance department satisfaction of students.
