Central odontogenic fibroma (COF) is a rare benign tumor that accounts for 0.1% of all odontogenic tumors. A case of COF (simple type) of the mandible in a four-year-old boy is described in this report. The patient showed asymptomatic swelling in the right inferior border of the lower jaw for one week. A panoramic radiograph showed a poorly-defined destructive unilocular radiolucent area. Cone-beam computed tomography showed expansion and perforation of the adjacent cortical bone plates. A periosteal reaction with the Codman triangle pattern was clearly visible in the buccal cortex. Since the tumor had destroyed a considerable amount of bone, surgical resection was performed. No recurrence was noted.

Rheumatoid arthritis, osteoarthritis, and periodontal disease are bone destructive diseases mainly caused by inflammation. Various studies are being conducted to develop treatments for inflammatory bone destructive diseases. Many of these studies involve plant-derived natural compounds. In these studies, cell differentiation, signal transduction pathways, and bone resorption were measured at the cellular level. In disease-induced animal models, the amount of inflammatory mediators or matrix destructive enzymes and serum metabolic markers were measured. This study examined the effects of plant-derived natural compounds, such as flavonoids, on inflammatory bone destructive diseases. In addition, we structurally classified various substances used to maintain bone health and summarized the biological effects and related mechanisms of the components.

Through researching 鄕藥救急方, the oldest medical text published in Korea in existence known to date, a study from a Traditional Korean Medicine perspective was conducted. This study aims to observe the treatment of oral, glottal, labial, and dental diseases starting from 統一新羅時代 to the Koryo dynasty from a historical perspective and also find out what clinical significance it withholds. "鄕藥救急方" proposes methods of nurturing the teeth and in doing so displays the tendency of Traditional Korean Medicine of putting much weight on preventing diseases and nurturing the body. "鄕藥救急方" considers the oral, glottal, labial, and dental diseases as not only fundamental problems in itself but also treats them from a perspective that they are results of disharmony among the five viscera and the six bowels. The treatment methods mentioned in "鄕藥救急方" are directly cited in "鄕藥集成方" of early Chosun dynasty. In "東醫寶鑑" of mid-Chosun dynasty, however, changes and modificatios are made to the prescriptions.

Taste is closely related to intake of food. Taste perception is also influenced by type of food ingested, and nutrition and health status. Bitter taste plays an important role in the survival of human and animals to avoid probable toxic and harmful substances. Vertebrate animals recognize bitter taste through type 2 taste receptors (T2Rs). Several T2Rs have been expressed extra-oral such as the gastrointestinal tract, respiratory tract, urogenital tract, brain and immune cells, and parts of their functions are being revealed. This review will discuss physiological roles of T2Rs in relation to innate immunity, secretion and smooth muscle contraction expressed in extra-oral cells and tissues, and we summarize relationships between polymorphisms in T2Rs and general or oral diseases. It is not a coincidence that animals pay much genetic costs for taste and smell during evolution.

In chronic temporomandibular disorders (TMDs), constituent tissues such as muscles are sensitive to pain and psychological stress, which negatively affect the quality of life. In addition, since chronic TMDs is often accompanied by diseases such as psychological disorders and other chronic pain disorders, the diagnosis of those diseases and patient referrals are mandatory. The management of chronic pain in TMDs requires a multidisciplinary and holistic approach. Pharmacological therapy using cyclobenzaprine, serotonin and norepinephrine reuptake inhibitors, tricyclic antidepressants, progressive relaxation, and psychological approaches using cognitive behavioral therapy such as shifting negative thoughts about pain are all valid treatment options.

Objectives : The purpose of this study was to examine the factors related to the dental caries and periodontal diseases of Korean elderly people in terms of demographic characteristics, oral health promotion behavior and systemic diseases in an effort to provide information on national policy setting and policy evaluation about the prevention of tooth loss resulting from severe oral diseases and the promotion of elderly people's oral health. Methods : The first-, second- and third-year raw data of the 4th National Health and Nutrition Survey were utilized, and the data of 3,882 elderly people who got a dental checkup were analyzed. The statistical package SPSS WIN 19.0 was employed to make a logistic regression analysis. Results : The senior citizens who did toothbrushing less frequently were more likely to have dental caries. As for periodontal diseases, the men were 1.34-fold more likely to have periodontal diseases than the women, and the respondents whose self-rated health state was worse were 1.40-fold more likely to have periodontal diseases than the others whose self-rated health state was better. The senior citizens who ever received treatment from unqualified people were 1.30-fold more likely to have peridontal diseases, and those who took neither vitamin compound nor minerals were 1.30-fold more likely to have periodontal diseases. Those who suffered from low High-density Lipoprotein cholesterol(HDL) were 1.35-fold more likely to have periodontal diseases than the others who didn't. Conclusions : Those whose self-rated health status is worse should especially be concerned about periodontal diseases. Specifically, it's needed to pay attention to the low-income classes, and the government should take measures to provide quality welfare services for elderly people not to receive treatment from unqualified people. Besides, research efforts should be made to determine the relationship between periodontal diseases and low HDL-cholesterolemia.

Background: Conventionally, indirect radiography has been used to diagnose salivary gland diseases. However, with the development of sialendoscopy, diagnosis and treatment of salivary gland diseases have become more effective. Herein, we report a case of sialolithotomy treated with sialendoscopy and compare it with the existing methods through a literature review. Case presentation: Two patients with a foreign body sensation under the tongue and dry mouth visited the Anam Hospital, Korea University. Radiographic examination revealed salivary stones inside the right Wharton duct, and the patients underwent sialolithotomy under local or general anaesthesia. The stones were totally removed, and there were no postoperative complications such as bleeding or pain. Conclusion: The development of sialendoscopy has enabled better definitive diagnosis of salivary gland diseases compared with the conventional methods; better treatment outcomes can be obtained when sialendoscopy is used in appropriate cases.

The purpose of this study was to identify chronic diseases and oral health care behaviors in 65-year-old individuals and to determine the factors that influence masticatory mobility. The raw data from the 8th National Health and Nutrition Examination Survey in 2020 were utilized to analyze factors associated with chewing discomfort in 1,278 elderly Koreans. Using IBM SPSS Statistics 27.0, we conducted complex sample cross-analysis to examine the difference in chewing discomfort based on general characteristics, chronic diseases, and oral health care behaviors. Additionally, we performed complex sample multiple logistic regression analysis to identify the factors associated with chewing discomfort. As a factor influencing chewing discomfort, unmet dental care was 3.33 times higher (p<0.001), and subjective oral health was 0.18 times more likely to be moderate (p<0.001) and 0.48 times more likely to be good (p<0.001) lower. In the case of arthritis, the level of chewing discomfort was high (OR=1.08, p=0.694), but there was no significant difference. As a result of the aforementioned factors, it is believed that there is a need for policies and systems to provide dental care to the elderly before their oral health deteriorates. Additionally, tailored oral health promotion programs should be implemented.

본 연구는 심뇌혈관질환위험군의 구강건강인식과 구강건강행위가 심뇌혈관질환 예방행위에 미치는 영향을 파악하여 간호중재 프로그램의 기초자료로 제공하고자 한다. 자료수집은 전라남도에 소재한 2개의 종합병원 및 보건소, 보건진료소, 노인복지관에서 관리하고 있는 심뇌혈관질환위험군 131명을 대상으로 설문지를 통하여 조사하였다. 연구기간은 2018년 2월부터 3월까지 2개월간 시행되었다. 수집한 자료는 기술통계와 t-test, Pearson 상관분석, 단계적 다중회귀분석으로 분석하였다. 연구결과 심뇌혈관질환 예방행위는 치주질환인식인 주관적 구강건강상태(r=.261, p=.003), 구강건강의 중요성(r=.250, p=.004), 그리고 구강건강행위(r=.303, p<.001)와 양의 상관관계가 있었고, 심뇌혈관질환 예방행위에 영향을 미치는 요인은 구강건강행위(${\beta}=.29$, p<.001), 연령(${\beta}=.27$, p=.001), 주관적 구강건강상태(${\beta}=.24$, p=.003)로 나타났다. 즉, 구강건강행위가 높을수록, 연령이 높을수록, 주관적 구강건강상태가 좋을수록 심뇌혈관질환 예방행위의 점수가 높아진다고 할 수 있다. 이들 변수의 설명력은 19.3%이었다. 따라서 심뇌혈관질환위험군의 구강건강 수준을 향상시키기 위한 교육 및 중재프로그램 개발이 필요하며 구강건강 인식, 태도 및 행동과 구강건강상태 등에 관한 지속적인 추후연구가 필요할 것이다.
