Swallowing disorders or dysphagia, which are difficulties with the act of swallowing, can occur at different phases such as oral, pharyngeal, and esophageal phase in the swallowing process. These disorders can be caused by structural, functional abnormalities or psychological problems. Dentists can actively provide patients suffering from dysphagia with comprehensive professional care, especially from the cognitive stage of food to the pharyngeal stage of the swallow. Many cases of dysphagia can be improved with careful managements based on dental professionals' knowledge, including meticulous evaluation of masticatory and swallowing functions, training on eating and swallowing, and fabrication of palatal or lingual augmentation prosthesis. The important thing is that prevention of these disorders through the oral health care instruction and planned follow-up dental visit at periodic intervals in order to manage the problems caused by anatomical, functional, and psychological reason.

Many people in Korea suffer from a fear of dental treatments; however, only a few studies have focused on this population. This study assessed the effectiveness of cognitive behavioral therapy (CBT) and its interventions in reducing dental anxiety, especially when administered by trained dental staff. Using case studies, the authors analyzed the content of each session and examined the process of reducing dental anxiety. First, the authors observed that the results of both dental fear scale and subjective unit of disturbance decreased significantly with changes in cognitive distortions related to dental anxiety and that rapid improvements were noted after two therapy sessions. Second, the study reported that practicing relaxation (deep-breathing) and muscle relaxation techniques; using hand signals to indicate anxiety or discomfort; establishing an empathic relationship with the therapist; making an anxiety list; and graded insensitive and exposure along with rehearsal, were effective in coping with dental anxiety and in changing negative thoughts towards the dentist. Third, a simple cognitive behavioral intervention can be effective in reducing dental anxiety. In summary, a short-term, five-session psychological intervention with CBT produced a sustained decrease in the symptoms of dental anxiety, allowing the patients to receive the required procedures. The authors discussed the study limitations and the implication of their results on future research.

Full-mouth rehabilitation with increasing vertical dimension can be used for patients with severely worn teeth. In severely worn teeth also, the alveolar process can be elongated to compensate for the reduced vertical dimension, and the patient's vertical dimension of occlusion can be kept constant. However, full-mouth rehabilitation with increasing vertical dimension must be carefully chosen, because the vertical dimension can be reduced by tooth wear. It is important to establish a treatment plan with the systematic diagnosis of the change in the vertical dimension and gain space for the prosthesis. It is necessary to change the vertical dimension to secure the restoration space and select the minimum vertical dimension elevation for the esthetic and functional goal. In this case report, the patient complained of difficulty during chewing due to a worn dentition and wanted esthetic improvement of the short mandibular anterior teeth. After systematic evaluation and diagnosis, we performed full-mouth rehabilitation with minimum vertical dimension elevation to obtain the space for restoration. This resulted in a stable and harmonious occlusion, and the functional and esthetic problems of the patient were solved after treatment. The patient was satisfied with the results of the treatment and maintained stable occlusion during the follow-up period.

The aim of this study was to measure the dental anxiety, the factors associated with dental anxiety and the utilization behavior of dental treatment. Modified dental anxiety scale(MDAS) and Dental fear survey(DFS) were used as measurement, where through the mean and the standard deviation were worked out and also the T-test and ANOVA were performed. In relation to MDAS, females and males showed the mean, '$2.86{\pm}0.06$' and '$2.49{\pm}0.06$' (p=0.000). Also, less than 20 and more than 21 showed the mean, '$2.81{\pm}1.01$' and '$2.61{\pm}0.99$' (p=0.023). In relation to dental utilization behavior, the subjects were classified into three groups, a group who uses dental clinics periodically, a group who uses them only when problems arise, and a group who has not ever used them. MDAS indicated a higher value in the group who use dental clinics only when problems arise, which was significant statistically (p=0.000). In the case of MDAS, many respondents answered that they felt anxious in the process of actual treatment; in the case of DFS, they felt anxious due to the factors that cause irritation.

Aesthetics means differ from cultures and times and also differ from each person's own thinking. But as a restorative dentist who works for esthetic areas, we need to have certain principles and rationale. Some functions in CAD/CAM looks very useful to match harmonious shape to adjacent teeth and also very effective and efficient when compare to the traditional laboratory technics. Also we will discuss about link abutment (Titanium-Zirconia abutment) which we need for dental implant placed anterior area where the soft tissue is thin.

In dental esthetics, soft tissue plays an important part, probably very large portion of it. A clear understanding of the periodontal tissues and its management around teeth and implants help us to develop concepts for a modern dental treatment that addresses the needs of demanding patients in regard of esthetics and durability. When we talk about esthetic, we can say that one of the most important element is a harmonization with gingiva (soft tissue) called 'Pink Esthetic' As for the pink esthetics, gingival line(contour) takes most of the influence on esthetic result; it consists of labial gingival level, interproximal papilla height, and a line that connects them. In the gingival recession, labial gingival level and gingival contour move to the apical portion, and the root area is exposed. It leads to the unesthetic result. Root coverage technique is classically used to treat gingival recession (marginal tissue recession) of natural teeth. It is an essential technique on periodontal plastic surgery part. It is also a very useful technique to recover soft tissue problems in implant dentistry. So, root coverage technique must be mastered for a good implant esthetic result. The general overview of root coverage procedures will be discussed with step by step explanation to get more esthetic result.

Child abuse often interferes with the normal and healthy development of a child, bringing about various complications and problematic behaviors. Furthermore, such physical, mental abuse or neglect, and sexual abuse on a developing child may have serious effects even until after adolescence. The types of injuries caused by physical abuse vary, but some types of injuries are common. A great number of them can be detected during a routine dental examination because many of these injuries are present in the facial and dental region. Accordingly, in the case of abused children, it is important to find the signs of abuse through regular dental checkups, as many suffer injuries to the face, head and neck area including the oral and perioral area. As a pediatric dentist, it is the legal and social obligation to contribute to preventing and assisting the struggle against child abuse. The authors contemplate ways for all pediatric dental related personnel to find some clinical signs and symptoms of child abuse to help early detection, and to manage the situation properly.

Dental professionals are exposed to various occupational risks, among which the problem of hearing damage has been newly revealed. There have been some researches reporting that noise occurring in a dental office exceeds the Occupational Safety and Health Act (OSHA) Standards. Especially, the pediatric dentists are repeatedly exposed to an additional noise source called the crying sound of children in addition to all kinds of noises from dental instruments. Accordingly, this study intended to investigate the noise environment likely to affect pediatric dentists and to examine the possibility of resultant hearing damages. The level of noise was measured respectively, when various dental instruments (ultrasonic scaler, high-speed handpiece, low-speed handpiece) are operated, when children are crying, and when both occasions take place simultaneously (from the distance of 30 cm) with a portable noise meter. And the daily duration of pediatric dentists exposed to the noise environment was surveyed. The results were compared with the standard value of noise threshold of NIOSH, OSHA, and that of hearing damage of CRA News letter respectively. Considering the intensity and exposure time, the noise environment of pediatric dentists exceeds the allowable noise threshold values. Even only one exposure to crying child was likely to lead to permanent hearing damage. Comparatively, pediatric dentists have a higher risk for occupational hearing damages, and some active measures are thought highly desirable to minimize it.

Chronic infantile neurological cutaneous articular (CINCA) syndrome periodically causes fever along with inflammation in multiple organs. Patients with this condition are vulnerable to dental problems due to systemic inflammation. For uncooperative patients, general anesthesia has been widely used to control negative behavior. However, caution should be exercised when administering general anesthesia in these patients because this syndrome is pro-inflammatory. The present case report describes the clinical considerations of the dental treatment of an uncooperative child with CINCA syndrome who was treated under general anesthesia.

In the field of dentistry, there existed relatively few emergency patients or patients who need intensive care and thus had low medical dispute rates. However, these days, there is a general tendency of increased medical disputes. Although many medical disputes are caused by medical accidents of the dentists, because dental assistants are also lawfully involved in practicing dentistry, there is a possibility of medical disputes or medical accidents caused by dental assistants. Therefore, the role of the dental assistants cannot be ignored. This study consists of a survey given to dental hygienists currently working in general hospitals, dental hospitals and private dental clinics. Following is the results of the analysis of 275 respondents' backgrounds, medical disputes rates including patients' complaints, their understanding of medical regulations and their general understanding of overall dental practice and medical disputes. 1. 251 of 274(91.6%) respondents doubted the risk of medical accident and dispute. 2. 81(29.5%) dental hygienist experienced complaint from patients. They have been working in the private dental clinic, the rate of this experience was high. 3. 349 case of 1805(19.3%) the complaints by patients, highest percentage among its category, were those regarding dental fees and poor service. 4. 129 case of 1805(7.1%) patients' complaints, highest percentage among it's subcategory, were those regarding the absence of explanations of precautions or request of agreements before dental treatment. 5. 252 of 267 (94.4%) dental hygienists chart after a scaling treatment. However, only 55(20.7%) dental hygienists chart the fact of explaining the precautions. 6. 6(2.2%) dental hygienists do not inspect patients' medical history, if patients don't mention it. 7. 104 of 274(38.0%) dental hygienists responded to be capable of administering first aid treatment. 8. 115(41.8%) dental hygienists have a first aid kit and equipment. 9. In case of medical dispute, 268(97.8%) dental hygienists respond that, charting plays a big role in resolving the dispute. 10. In case of medical dispute, 272(93.3%) dental hygienists respond that, explanation and agreement before treatment have an important role in settlement of dispute 11. Only 160(58.4%) dental hygienists responded correct answer that the duration of keeping medical records is 10 years. 12. 124(45.3%) respondents thought that it is legal for a dental hygienist to take a panoramic dental X-ray, 71(25.9%) respondents thought that it is legal practice cervical resin treatment by dental hygienist, and 37(13.5%) respondents thought that it is legal extract primary teeth by dental hygienist. 13. 24(18.76%) respondents thought that it doesn't matter to tell patient's state to others 14. 272(99.27%) responded that receiving education for the prevention of medical disputes was needed and of them, 61.0% thought it was urgent. 15. 186(64.2%) has never had classes regarding the prevention of medical disputes while in school and 212(77.4%) has not had the same type of classes after graduating from school. 16. 256(93.4%) responded that there will be even more of an increased number of medical disputes. Among them, 83.3% of respondents though that due to the increased opportunity of acquiring information through the internet and mass media. The study shows that 29.5 percentage of dental hygienists have experienced the medical disputes and complaints and they are lack of recognition of medical regulations and dental hygienist's official duty. So, there is a big potential of the percentage to increase. Therefore, the correct understanding of explaining precautions and requesting agreement before dental treatments and performing them are mandatory. Moreover, classes regarding the prevention and counterplans of medical disputes need to be widely offered.
