Biopsy is a critical method for disease diagnosis and treatment planning. It can be applied from simple inflammatory lesions to malignant tumors. But many general dental practitioners are unfamiliar with the basic knowledge and skills required for biopsy. Moreover, biopsy indications and contraindications for certain diseases may differ depending on the type of dental practice environment and the specialty of the dentist. Biopsy education can increase the choices a dentist has during disease diagnosis. Here we will discuss details on biopsy needed to the general dentist.

Objectives: The purpose of the study was to investigate the related factors to dental fear in some adults. Methods: A self-reported questionnaire was filled out by 320 adults in Seoul and Gyeonggi-do from April to June, 2013. Except 14 incomplete answers, data were analyzed by SPSS 18.0 program. The questionnaire consisted of general characteristics of the subjects(7 questions), dental fear related factor(18 questions), distrust for dentist(15 questions), and distrust for dental hygienist(11 questions). The instrument for dental treatment fear was Dental fear Survey(DFS) adapted from Kleinknecht and partly modified by Choi. Out of 20 questions, 18 questions were reconstructed and score by Likert 5 scale. Higher score means higher dental fear. Cronbach alpha was 0.959 in the study. The distrust for dentist and dental hygienist was adapted from Choi and reconstructed and score by Likert 5 scale. Higher score means higher distrust for dentist and dental hygienist. Cronbach alpha was 0.937 in distrust for dentist and 0.874 in distrust for dental hygienist in the study. Results: Those who experienced dental pain tended to have dental fear. The reasons for dental fear were as follows; bad breath(2.96 out of 5 points, hereafter represented as of 2.96/5), dental caries(2.88/5), missing teeth(2.87/5) and tooth pain(2.77/5). The distrust for the dentist was the main dental fear in the adults. Conclusions: The dental fear was closely related to gender, experience of dental pain, oral symptoms and distrust for the dentist. As the psychological pain in the patients was mainly influenced by the trustful atmosphere, it is necessary to make the patient easy before treatment.

The subjects chosen for the study were 2,941 dentists who have been registered in the Seoul Dental Association in 1997. Questionnaires were delivered to the dentists, and 1,133 questionnaires of these were returned. The basic dental of repliers, medical accident experiences, and general thoughts on the dental care and medical accident had been reviewed. Many dentists had appeared to be exposed to the medical accidents and disputes, and the rate of the experience of these cases was also high. In the dental practice, the execution degree of the duties as a dentist was lower than the perception of the duties as a dentist, while the perception was good. However, in spite of carefully following the duties as a dentist, it seemed to be impossible to fundamentally prevent the medical accidents. Thus, dentists should always predict the possibilities of the medical accidents, and it is necessary to establish the impartial dental institutions and organizations through which dentists can settle the medical disputes.

White lesions of the oral mucosa are a common clinical finding that often present first to general dentist. Some white lesion may have possibility of malignancy. Leukoplakia is the most common "potentially malignant disorder" of the oral mucosa. Leukoplakia is at present defined as "A white plaque of questionable risk having excluded (other) known disease or disorders that carry no increased risk for cancer.". Therefore, it is important for general dentist to be familiar to clinical differential diagnosis of leukoplakia from the known white lesions such as candidiasis, lichen planus, leukoedema, frictional keratosis, and so on. It is also important to decide whether such lesions require further investigation through the biopsy. As a result of biopsy, the presence of epithelial dysplasia in the leukoplakia is still the strongest predictor of future malignant transformation. In this article, oral white lesions that must be differentiated from potentially malignant disorders or early invasive squamous cell carcinoma will be reviewed together with presenting clinical cases.

Objectives: The purpose of this study was to examine how the dentist's servant leadership affects the happiness index of dental hygienists. Methods: The subjects were 221 dental hygienists that have been working at dental clinics or dental hospitals. The data were analyzed using SPSS Version 20.0 (IBM Co., Armonk, NY, USA). An independent t-test and one-way ANOVA analysis were conducted to examine the difference in the happiness index of dental hygienists according to general characteristics. The independent t-test was conducted to examine organizational culture and happiness index according to upper and lower group based on the mean score for servant leadership. Pearson's correlation analysis was used to examine the correlation among key factors. Multiple regression analysis was conducted to identify factors influencing the happiness index of dental hygienists. Results: According to the analysis, there was a statistically significant positive correlation between the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists. However, a stewardship of the dentist's servant leadership factors was not found to have any correlation with the market culture. A multiple regression analysis was performed after including the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists. Meanwhile, the stewardship and community-building effect of the dentist's servant leadership had a statistically significant effect on the happiness index of dental hygienists. Consequently, a higher servant leadership factor in dentists was correlated with a higher happiness index of dental hygienists. Conclusions:The findings show that the dentist's servant leadership affect the happiness index of dental hygienists. Therefore, effective intervention and education programs related to the dentist's servant leadership and sound organizational culture are necessary to enhance dental hygienists' happiness index. Additionally, a follow-up study will determine the causal relationship among the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists, considering organizational members and the environment of the dental clinics.

Background: Dental evaluation and protection are important for preventing traumatic dental injuries when patients are under general anesthesia. The objective of the present study was to develop a questionnaire based on dentition-related risk factors that could serve as a valuable tool for dental evaluation and documentation. Methods: We developed a questionnaire for dental evaluation before administration of general anesthesia, investigated the association between patient-and-dentist responses and mouthguard fabrication, and assessed response agreement between 100 patients. Results: Protective mouthguards were fabricated for 27 patients who were identified as having a high risk of dental injury. There was a strong association between dentists' responses and mouthguard fabrication, depending on the general oral health status, use of ceramic prosthesis, presence of masticatory pain related to periodontal diseases, gingival edema, and implants (P < 0.05). Response agreement between patients and dentists for items related to dental pain, loss of dental pulp vitality, root canal therapy, dental trauma, aesthetic prosthesis, tooth mobility, and implant prosthesis was high (Cohen's kappa coefficient κ ≥ 0.6). Conclusions: A high agreement was observed between patient-dentist responses and a strong association with mouthguard fabrication for items pertaining to ceramic prosthesis, masticatory pain, and dental implants. Patients with a "yes" response to these items are recommended to undergo a dental evaluation and use a dental protective device while under general anesthesia.

Dentists have been striving to find ways to relieve patients' pain and discomfort. The prestige of dentists is made up of dentists' self-sacrifice, academic research and pursuit of patients' well being. However, nowadays the dentists' prestige has been lost and practice on humanity has merely existed. At this time, it is meaningful to shed new light on life of a pioneer in Korean dentistry and take some time for self-examination. Today, we are going to look into life of Dr. Jong-Suh Ahn and his achievements in Korean dentistry. In 1925, Dr. Ahn Jong Suh graduated from KyungSung Dental school as a first graduating class. Then, he learned advanced dentistry at Severance Hospital and in April of 1932 as a young dentist with full of potentials, he opened his dental clinic in Tianjin, China. As an awakening Korean, in 1925 he organized an association of Korean dentists, called HanSung Dental Association and worked as a secretary to manage general affairs. Han Sung Dental Association later became today's Korean Dental Association. On December 9th, 1945, he founded ChoSun Dental Association. He accomplished great deals during his five consecutive terms as a chairman and held other important positions with prestige to lead and expand the scope Korean dental association. There were three other successors to Dr. Ahn as the presidents of Dental Association. Dr. Yong-Jin Kim had a great interest in internal affairs and dental materials. Dr. Myung-Jin Park was active in scientific affairs and Dr. Dong-Chan Han focused on smooth operation of the association. From 1945 to 1963, Dr. Ahn submitted important agendas such as dentist's qualification, scientific and academic affairs, general affairs, dental materials, public oral health, and dental administration to Dental Association's general meeting and central committee. Dr. Ahn overcame hardships of Japanese imperialism, celebrated independence of Korea, experienced 6.25 Korean War and lived through evolving Korean dentistry in 1960s. Dr. Jong-Suh Ahn, who showed the prestige of dentist and expanded the scope of dental association, is exemplary to all dentists.

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.

The purpose of this research is to assess the geographical distribution of physicians and dentists and the degree of maldistribution of the physician. Data were obtained form the Korean Medical Association's report on physicians registry and census for 1990. To assess the degree of disparity in the rural-urban distribution of physician manpower and to identify changes in the distribution pattern, the Gini index of concentration was used. Major findings are as follows; 1. Urban-rural disparity in the distribution of physician manpower exists in all categories of manpower, i.e. physician, dentist, oriental medical doctor, general practitioner, medical specialist, practitioner, public health physician and public health dentist. Urban area which had 74.4% of nation's population, accounted for over 90% of all physician manpower. 2. In terms of the ration of physician manpower per 10, 000 population, in urban area, they were 8.2 physicians, 2.7 general practitioners, 5.5 specialists, 3.0 practitioners, 1.8 dentists and 1.3 oriental medical doctors. In rural area, the ratios were 1.4 physicians, 0.6 general practitioners, 0.9 specialists, 1.0 practitioners, 0.4 dentists and 0.4 oriental medical doctors. 3. Gini indicies computed to measure inequality of physician manpower distribution were 0. 3675 for physicians, 0.3372 for general practitioners, 0.3338 for specialists, 0.2263 for practitioners, 0.3132 for dentists and 0.3293 for oriental medical doctors. 4. Inspite of increase in the number of physician manpower, urban concentration of physician manpower intensified from 1980 to 1990. However, the Gini index for all physician manpower fell by 18.3~36.7% from 1980 to 1990, indicating more even distribution. 5. In rural area, the public health physicians and dentists had increased the ratios of physicians, general practitioners, practitioners and dentists per 10, 000 population remarkebly, and had decreased the Gini indicies of physicians, general practitioners, practitioners and dentists. Thus, public health physicians and dentists contributed to improve the distribution of physician manpower in rural area. Based on the results of this study, long-term and rational manpower policies should be developed to solve the problem of geographical maldistribution of physician manpower as well as short-term policy for inducing physicians to the rural areas.
