Background: The purpose of this study was to utilize text network analysis and topic modeling to identify interconnected relationships among keywords present in patent information related to oral health, and subsequently extract latent topics and visualize them. By examining key keywords and specific subjects, this study sought to comprehend the technological trends in oral health-related innovations. Furthermore, it aims to serve as foundational material, suggesting directions for technological advancement in dentistry and dental hygiene. Methods: The data utilized in this study consisted of information registered over a 20-year period until July 31st, 2023, obtained from the patent information retrieval service, KIPRIS. A total of 6,865 patent titles related to keywords, such as "dentistry," "teeth," and "oral health," were collected through the searches. The research tools included a custom-designed program coded specifically for the research objectives based on Python 3.10. This program was used for keyword frequency analysis, semantic network analysis, and implementation of Latent Dirichlet Allocation for topic modeling. Results: Upon analyzing the centrality of connections among the top 50 frequently occurring words, "method," "tooth," and "manufacturing" displayed the highest centrality, while "active ingredient" had the lowest. Regarding topic modeling outcomes, the "implant" topic constituted the largest share at 22.0%, while topics concerning "devices and materials for oral health" and "toothbrushes and oral care" exhibited the lowest proportions at 5.5% each. Conclusion: Technologies concerning methods and implants are continually being researched in patents related to oral health, while there is comparatively less technological development in devices and materials for oral health. This study is expected to be a valuable resource for uncovering potential themes from a large volume of patent titles and suggesting research directions.

Purpose: Many home care treatments can be used to promote the health and longevity of dental implants; however, few studies are available to support the concept that self-performed oral hygiene behaviors are an essential tool for improving and maintaining oral health. We investigated age-stratified associations between dental health behaviors related to tooth brushing (TB) and oral hygiene product use in Korean adults with implants. Methods: A total of 1,911 subjects over 19 years of age who had 1 or more implants and who participated in the 2013 to 2015 Korea National Health and Nutrition Examination Survey were reviewed. Periodontal status was assessed using Community Periodontal Index (CPI) scores, and periodontitis was defined as a CPI greater than or equal to 3. The complex sampling design of the survey was utilized to obtain the variance and individual weight of each analyzed factor. A high CPI was the outcome variable, and the main explanatory variables were oral hygiene behaviors, such as TB, dental floss (DF), interproximal brushing, and mouth rinsing. Results: Almost all individuals with a lower CPI brushed their teeth twice or more per day, in contrast to those with a higher CPI, and were likely to use DF. The adjusted odds ratio of not using DF for a higher CPI was 1.83 (95% confidence interval, 1.35-2.49). Conclusions: TB was implemented more than twice a day by patients with good oral health, and the combination of TB and DF significantly reduced the prevalence of a higher CPI. Self-performed oral hygiene practices combining TB and DF were significantly related to a low prevalence of periodontitis in implant patients.

본 연구는 비건의 건강 트렌드 속에 구강건강 영역을 포함시키기 위한 연구 개발의 필요성을 알리고자 20대 이상 비건 식습관 실천자 109명을 대상으로 조사하였다. SPSS을 이용하여 빈도분석, 카이제곱 검정, 단순선형회귀분석을 실시하였다. 완전 채식인 비건 집단은 주관적인 치아우식증 위험도가 낮게 나타났으나, 주관적인 구강건강에 대한 인식은 부정적으로 나타났다. 이는 비건 식습관이 구강건강의 면에서 조금 더 유익할 것이라고 믿으나 실제 구강건강도에서는 취약하다고 인지하는 것으로 나타났다. 이러한 결과를 바탕으로 뉴노멀 시대에서 비건이라는 새로운 식생활 소비 트렌드를 반영한 식습관 개선 방향 및 구강-영양 프로그램 개발의 필요성을 제시하고자 한다.

Halitosis is primarily caused by bacterial decay. The bacteria, which originate from biofilms such as dental plaque, show abnormal proliferation due to dental caries, periodontal diseases, soft tissue infections, and tongue diseases. Most studies on halitosis have exclusively focused on gram-negative bacteria in the oral cavity rather than on general oral microorganisms including oral fungi. This study analyzed oral fungal hyphae, as well as distribution and motility of oral microorganisms, and provided basic data on the control of halitosis. Our results revealed that the greater is the number of cocci bacteria, the higher is the halitosis value, or bad breath value (BBV), suggesting that cocci have a strongly positive correlation with halitosis (r=0.379, p=0.030). Moreover, there was no significant difference in the morphology or distribution of motile bacteria and motility score, with respect to BBV. Lastly, we investigated the relationship between halitosis and oral fungal hyphae. We found that a higher BBV corresponded with a greater number of fungal hyphae and that patients with fungal hyphae scored a higher BBV. However, this result was not statistically significant. In conclusion, this study provided the preliminary data on oral microorganisms and halitosis, but further studies are needed to analyze the relationship between oral microorganisms and halitosis.

Objectives: The purpose of this study was to explore the general public's perception and status of oral muscle strength training, to develop age-appropriate educational media and training methods, and to promote the need for oral muscle strength training. Methods: Data were collected from 15 individuals across different age groups (young, middle-aged, and elderly) from December 2022 to February 2023 through focus group interviews, and they were conducted twice for each group in a face-to-face manner. Results: Four key categories were identified: lack of information, effectiveness of training, need for promotion, and factors necessary for implementation. The following themes emerged: lack of information, need for training, age-specific characteristics, need for repetition, age at which training is needed, lack of promotion, need for promotion, number of practitioners, willingness to practice, and appropriate media for training. Conclusions: Awareness of oral muscle strength training was found to be very low, and it is necessary to improve awareness through continuous information and appropriate education on its need among the public. Additionally, quality content or media that can be easily applied for effective training should be developed, and personnel who can perform training efficiently should be trained.

Objectives: This study aimed to understand the definitions, types, and principles of computer-aided design/computer-aided manufacturing (CAD/CAM) and scanners due to the introduction of digital workflows. Methods: This study was based on information from the government's law and articles published in academic journals. Results: CAD/CAM is a technology that measures the shape three-dimensionally, saves it as data, designs it into the desired shape, and processes the product. Scanners, which are classified as intraoral and extraoral scanners, measure teeth and the intraoral environment three-dimensionally and convert them into three-dimensional (3D). A 3D printer is a machine that creates a 3D object by layering materials based on a 3D drawing. It can be classified into four types according to the method: extrusion, powder bonding, lamination, and photopolymerization methods. The most used 3D printer methods in dentistry are stereolithograhpy and digital light processing, and they are widely used in prosthetic, surgical, and orthodontic fields. Conclusions: As the dental system is digitized, it is expected that the government will classify the dental hygienist scope of work and the universities will reflect the curriculum; it is necessary to develop excellent dental hygienists, diversify the educational pathways, and establish policies to meet the needs of the increasing number of patients.
