Objectives: This study aimed to investigate the factors associated with unmet dental needs among adults with activity limitations. Methods: Data were obtained from the seventh Korean National Health and Nutrition Examination Survey (KNHANES). The final sample consisted of 945 adults aged 20 years or older with limited activity. Logistic regression analysis was used to examine the influence of predisposing, enabling, and need factors on unmet dental needs. Results: The proportion of adults with unmet dental needs during the last year was 52.2% in the middle-aged group and 45.5% in the older adult group. Higher household income was associated with fewer unmet dental needs in both groups. In the older adult group, married people were less likely to have unmet dental needs. In the middle-aged group, adults who perceived their oral health as poor were more likely to have unmet dental needs. Conclusions: All three factors (predisposing, enabling, and need) were found to be associated with unmet dental needs among adults with activity limitations. Special efforts should be made to improve access to dental care services for middle-aged adults with activity limitations.

The insurance payment plan for dental implants in Korea has been criticized because the payment priority has not been properly established, and the benefits are concentrated among middle-class citizens. In the current study, the relationship between the oral health condition and socioeconomic status of the elderly was analyzed using data from the Korea National Health and Nutrition Examination Survey (KNHANES). This study aims to determine the reason underlying the criticism of the insurance payment plan. The subjects were >65-year-old individuals in the 2010 and 2011 database of KNHANES. Data from 2,812 subjects were analyzed. The socioeconomic status was determined based on edentulousness, molar tooth loss, and presence of 28 teeth. According to the analysis, the average income was 1,560,000 won for edentulous elderly, 1,811,000 won for elderly who had lost molar teeth, and 1,896,000 won for elderly with 28 teeth (p<0.05). In addition, elderly with a low education level demonstrated a poor oral health condition (p<0.001). In conclusion, the insurance plan currently under examination is not properly designed for economically impoverished elderly because the plan only covers 50% of the costs and is limited to implantation of molar teeth only. This plan will not provide practical benefits to elderly with a poor socioeconomic status; therefore, the insurance payment plan needs to be improved so that the appropriate beneficiaries can be targeted.

Objectives: This study aims to assess the relationship between the body mass index and waist circumference, which are indicators of obesity, and dental caries according to gender. Methods: Data were used from the 6th Korean National Health and Nutrition Examination Survey (2013-2015). Out of a total of 29,321 subjects, 13,222 persons aged 19 or older and who responded to the survey items of this study were selected as subjects to determine the relationship between obesity and dental caries. Results: In the body mass index, the obese group had a higher prevalence of dental caries in both males (1.25 times) and females (1.35 times) than the normal group. Even in the underweight group, males were 1.83 times more likely to have dental caries than the normal group. In the waist circumference, the obese group had a 1.48 times higher prevalence of dental caries than the normal group in women only. Conclusions: According to the results of this study, it was observed that obesity was related to dental caries, and it was thought that obesity management and oral care education programs for adults in Korea were necessary.

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.

The original sample in this investigation included 36 children around the age of eight (mean age:8 year-lmonth) at the beginning. Study casts were obtained and measured every 6 months in two years of longitudinal study period in order to observe the changes of maxillary dental arch as well as the eruptional status of the maxillary lateral incisors. The results were as follows.: 1) The length of upper dental arch was increased gradually during the examination period. 2) The width between maxillary first molars was increased gradually during the examination period. 3) Intercanine distance in upper dental arch was increased gradually and the increment was conspicuous immediately after the eruption of maxillary lateral incisors.

Objectives: The study aimed to investigate the relationship between depression and number of present teeth in Korean elderly individuals. Methods: Data for this cross-sectional survey was obtained from the records of the sixth Korea National Health and Nutrition Examination Survey (KNHANES). The subjects were 1,199 Korean elderly individuals above 65 years of age. The survey and examination data were used for the independent variables. The KNHANES included health status, nutrition survey, and oral examination. $x^2-test$ was performed to identify the characteristics of depression and number of teeth present according to the characteristics of the study subjects. Logistic regression analysis was also performed to identify the relationship between depression and number of teeth present. The statistical significance level wa sset at 0.05. Results: The prevalence of depression in the subjects was 14.8%. There were statistically significant differences in the prevalence of depression, depending on gender (p<0.001), education level (p=0.001), income (p=0.001), spouse status (p<0.001), and alcohol consumption (p=0.020). The association between depression and the number of teeth present showed statistically significant difference after adjustment (p=0.040). Conclusions: Depression in elderly individuals was closely related to the number of teeth present. Therefore, public health policies for improving oral health should be established to prevent depression.

Objectives: To access the knowledge of undergraduate and postgraduate students of the dental college on basic anatomy, physiology, clinical examination, and pathology of the temporomandibular joint (TMJ). Materials and Methods: A total of 610 undergraduate and postgraduate students of dental college, were included in this study. The questionnaire was pretested for validation and distributed online through Google forms. Results: A pairwise comparison showed that the percentage of correct answers for interns significantly differed from that of IV Bachelor of Dental Surgery (P=0.050) and postgraduate students (P=0.048) (below average: up to 6 correct answers, good: 7-11 correct answers, excellent: 12 or more correct answers). Conclusion: TMJ diseases are common in daily life but frequently go undiagnosed and untreated due to a lack of clinical expertise. This demonstrates the necessity of providing instructions that give students in-depth knowledge and abilities for TMJ issues in clinical practice.

Objectives: This study aims to establish the concept of "dental assistance" within the dental field and to identify the scope of dental assistance, which can be utilized in order to distinguish the scope of work between jobs. Methods: The literature on dental hygienist work and dental assistance was reviewed, and the laws and precedents related to dental assistance were examined. Results: The criteria for judging the legitimacy of dental assistance included the following: whether the performance was conducted under the guidance and supervision of a doctor; whether there was a possibility of an aftereffect or side effects of the procedure; whether education was conducted within the curriculum; and whether it was evaluated in the national licensing examination. In addition, the work of the assistant in dental surgery and treatment is judged comprehensively by considering the type of dental surgery and treatment, invasive degree, necessity of expertise, and work proficiency of the dental hygienist. Therefore, it is suggested that dental hygienists may be of assistance for dental treatment/surgery because they meet the requirements of dental professionals, such as dental hygiene curriculum, national licensing examination, duties in the field of dentistry, and work proficiency. Conclusions: Dental assistance (including assistance in dental surgery) for dental treatment, dental/medical history taking, taking vital signs, and blood glucose monitoring should be permitted within the realm of dental hygienist work. Therefore, the actual expertise of dental hygienists should be reflected legally and the work of dental hygienists should be realized.
