Objectives : This study was to investigate the experience rate and factors related with Low Back Pain(LBP). Methods : Questionnaires were completed by 236 dental hygienists in Taegu city and Kyungpook province in June 23-27, 1999. The solicited information was used to estimate odds ration and $95\%$ confidence intervals for the LBP related factors association. Results : The experience rate of LBP was $78\%$. The experience rate of LBP was significantly associated with scaling posture(odds ratio=2.228)(p=0.0371) and stress with dentist(odds ratio=2.767) (p=0.0136). Conclusions : Data from this study support a statistically significant association between LBP and some factors found in other research to increase the relation with LBP. Study findings may have implications for targeting at dental hygienists for scaling posture education or intervention program.

A variety of mechanisms may generate pain resulting from injury to the peripheral nervous system. None of these mechanisms is disease-specific, and several different pain mechanisms may be present simultaneously in any one patient. Diagnosis of neuropathic pain is often easily made from the information gathered on neurologic examination and from patient history. Evidence of sensory disturbances elicited by examination combined with laboratory tests confirming injury to peripheral nerve establishes the diagnosis of neuropathic pain. Although treatment of neuropathic pain may be difficult, optimum treatment can be achieved if dentist has a complete understanding of the therapeutic options. Pharmacologic therapy has been the mainstay of treatment. Selection of an appropriate pharmacologic agent is by trial and error since individual response to different agents, doses, and serum level are highly variable. An adequate trial for each agent tried is key to pharmacologic treatment of neuripathic pain. If pharmacologic treatment is not effective, nerve block using lidocaine, steroid and alcohol and neurectomy must be considered for treatment option.

Objectives : The purpose of the study was to investigate the overall research trend and change in dental fear during 9 years(2004-2012) and to identify the major outcomes and future directions to research. Methods : Descriptive literature review was conducted for dental fear in Korea. The research setting should be elementary, middle, high schools and adults. Results : In this study, the literature review of the most used tools to measure fear was that DFS. The most commonly used instrument was Dental Fear Survey(DFS) in the literature review. The number of dacayed tooth was proportional to subjective fear and anxiety. The indirect experience of dental pain was heard from family and friends. So the fear caused the patients to have negative bias toward dental treatment. The negative reliability towards the dentist increased the dental fear to the patients. Conclusions : Through the literature review, dental hygienists are able to understand the dental fear of the patients.

The purposes of this study were to examine the effect of 35% Carbamide Peroxide(CP) bleaching agent on the changes in physical and chemical characteristics of tooth. The effect of bleaching agent on enamel was analyzed using Hardness test, SEM and EDS. The microhardness between bleached groups after bleaching showed statistically significant difference according to the paired t-test. The bleached enamel surface showed apparent morphological changes compared to the enamel, which was stored in distilled water only. The difference of the total mineral contents for the distilled water and Carbamide Peroxide did not show statistical significance. These results demonstrated that bleaching using 35% Carbamide Peroxide were adversely affects application time of experimental group and may the safety of using these agents for a short time in dentist-monitored bleaching.

Currently medical accidents suits are growing with increase of concern to oral health and dental office utility. Nevertheless this increase of medical accidents suits, the study on their cures are few. The purpose of this study was to investigate causes and preventive methods using case study of medical accidents. Cases were collected by the interview with dental practitioners in dental office. Collected cases were classified to seven fields of dental practice, four steps of dental practice, several causes, and methods of solution. Medical accident cases in field of oral and maxillofacial surgery were 58 cases, 53.4%. The accident cases in dental care step of dental practice were 78 cases, 70.3%. Also technical insufficiency and carelessness of dental practitioner during dental care were 26 cases, and 25 cases, 56 cases were solveded by reconciliation between dental patient and dentist.

In an edentulous situation, the oral rehabilitation with complete denture is substantially different from treatment of natural teeth. The artificial teeth arrangement and occlusion are important factor for the stability of the denture. Bilateral balanced occlusion is that stability of the denture is attained when bilateral contacts exist throughout all excursion and static states of the denture during function and, artificial teeth are arrangement in neutral zone where the forces between the tongue and cheeks or lips are equal. This is how dentist make a favorable prognosis. Therefore, dentists are have to be a little more involved in the selection and arrangement of artificial teeth.

Dentin bonding systems are unique dental materials which are rapidly evolute and essential materials for bonding of restorative materials to dentin. Now, 4th generation, 5th generation, 6th generation and 7th generation of dentin bonding systems are used in clinic. We investigated the frequency, motivation of choosing dentin bonding systems and satisfaction of them by survey in 2014. 5th generation of dentin bonding systems are mostly used in Korea and young dentist have tendency to choose newly developed dentin bonding systems.

The number of patients with dementia in Korea is estimated to be 576,000 in 2013 and 648,000 in 2015, and 840,000 in 2020 and 2,710,000 in 2050. Therefore, it can be expected that the number of patients with dementia will increase among the elderly patients who are looking for dentistry. Dementia and oral hygiene are closely related, so the future role of the dentist is very important. In order to treat effectively the patients with cognitive disorders, we should consider effective communication methods with them. Xerostomia is another important factor affecting oral health of dementia patients. In establishing the dental treatment plan, the most appropriate treatment method should be selected considering the characteristics of individual dementia patients and all possible efforts should be made for successful treatment results.

In our daily practice, we think about the diagnosis of our patient and get into a situation wherein we have to make a clinical decision. Diagnosis and treatment come from the knowledge and experiences that each dentist should have, but sometimes, we can have doubts on our decisions. "On what evidence did I make such decision? Was that really right?" Drawing our attention these days as a possible answer to this question, evidence-based dentistry seeks to apply the best available evidence gained from the scientific method to medical decision making. To make a good decision, the strength of evidence is assessed. Specifically, randomized controlled trial, systematic review, and meta-analysis are considered the highest level of evidence; cohort study, case control study, case series, animal study, bench test, and biological plausibility follow. With the approach of evidence-based dentistry, we can make objective, scientifically sound clinical decisions. It is also patient-oriented, incorporating clinical experiences and stressing good judgments; thorough and comprehensive, it uses transparent methodology. That is the reason evidence-based dentistry can be better than other assessment methods when we make a clinical decision in modern dentistry.

Metal - ceramic restorations have been the standard of fixed oral rehabilitation for over 30 years, and while many advances have been made in materials and research, the esthetic challenges of the light reflective metal substructure will always put clinician in an esthetic dilemma, for only a very talented ceramist / dentist team can create esthetics that rival nature on a repeatable basis. All ceramic restorations have also been a choice in our restorative armamentarium, but in the past, the materials have also had their own limitation, number on being question-able strength to withstand occlusal forces generated during mastication. IPS Empress 2 offers dentistry a metal free alternative to traditional restorative techniques. This clinical report describes the treatment of patients with esthetic problem of anterior dentition using Empress 2 system.
