Although the Korea National Health and Nutrition Examination Survey (KNHANES) calculates oral health functional restriction rate and chewing discomfort rate every year, these two indicators are not all indicators of oral health. Therefore, indicators are needed to subdivide by age group and cover dental caries, periodontal disease, remaining teeth, and oral care use. The purpose of this study is to identify the key indicators of oral health in mature and middle age. The average number of existing natural teeth, the rates of 20 or more natural teeth, complaints of chewing discomfort, oral examination, periodontal disease and dental caries, were analyzed using KNHANES VI (2013-2015) as a complex sample. In the age group between 40 and 64, there were 25.2 natural teeth remaining, 91.4% natural teeth retention rate, 23% chewing discomfort rate, 34.7% oral examination rate, 38.7% periodontal disease prevalence, 6.46 the number of caries experience teeth, 21.4% interdental brush usage rate.

The purpose of this study is to determine if natural extracts could be used as an additive in oral health food made with Weissella cibaria CMU (oraCMU). Natural extracts of green tea, mulberry leaf, licorice, and propolis, which are reported to have antimicrobial activities, were selected and used in this study. The minimum inhibitory concentrations (MIC) of extracts on periodontal pathogens such as Fusobacterium nucleatum and Porphyromonas gingivalis and their synergy effects with oraCMU by the fractional inhibitory concentrations methods were measured. From the results obtained, all the extracts showed no effect on the growth of oraCMU. Green tea extract showed the best antibacterial activity with MIC of 1.8 mg/ml against both F. nucleatum and P. gingivalis. In addition, green tea extract had a synergistic effect with oraCMU against F. nucleatum. Therefore, these results suggested that green tea extract is available as an additive in oral health food made with oraCMU.

Objectives: The purpose of this study is to evaluate the relationship between socioeconomic characteristics and prevalence of periodontal disease in a representative sample of Korean adults older than age 20. Methods: Data of 3,837 adults were collected by the six Korean National Health and Nutrition Examination Survey, which was conducted in 2015. Socioeconomic, demographic, and oral health-related behavior data were collected as independent variables. We determined frequencies, percentage, and determining statistical significance using multiple regression analysis. Results: Prevalence of periodontal diseases showed statistically significant difference in accordance with sex, age, socioeconomic and demographical characteristics and oral health-related behavior. It was confirmed that the prevalence of periodontal diseases was increased in the lower educational level and income (OR, 1.478 and 1.520) after adjusting for conditions such as age, sex, recent dental check-ups, visiting dental clinic, tooth brushing frequency, use of self-care devices. Conclusions: The prevalence of periodontal disease was related with socioeconomic factors in Korean adults. Therefore, differentiated oral health service policies and dental health education among adults with lower education and income is required in order to reduce the prevalence of periodontal disease.

Objectives: The purpose of this study was to confirm the relationship between socioeconomic characteristics and the prevalence of periodontal disease, with a focus on employment status, in a representative sample of Korean adults aged 19-39 years. Methods: Data were obtained from 3,178 adults who completed the Korean National Health and Nutrition Examination Survey, health-related questionnaires, and an oral examination. Socioeconomic, demographic, and oral health-related behavior data were adopted as independent variables. The chi-square test was used to assess differences in the distribution of socioeconomic status, oral health behavior, and nutrition factors according to employment status. Logistic regression analysis was performed to confirm the relationships between the prevalence of periodontitis and the related variables. Results: Significant differences in sex, educational level, income, marital status, smoking status, prevalence of periodontitis, number of dental check-ups in a year, and unmet dental care were confirmed according to employment status. The prevalence of periodontal disease was not significantly related to employment status. Conclusions: These results suggest a significant difference in periodontal disease according to socioeconomic factors in Korean adults. However, the prevalence of periodontal disease was not related to employment status. To prevent the progression of periodontal disease, attention should be paid to oral health, time available for dental treatment, smoking cessation, and use of floss.

Purpose: This study aimed to examine the prevalence and abundance of 9 representative periodontal pathogens in the saliva samples of periodontally healthy subjects (PH) and patients with periodontitis who underwent supportive periodontal therapy (SPT). The age-specific distribution of these pathogens in periodontally healthy individuals was also analyzed. Methods: One hundred subjects (aged >35 years) were recruited (50 each in the PH and SPT groups) between August 2016 and April 2019. The prevalence and abundance of periodontal pathogens in the PH group were compared with those in periodontally healthy young subjects (94 subjects; aged <35 years), who were included in our previous study. DNA copy numbers of Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), Treponema denticola (Td), Prevotella intermedia (Pi), Fusobacterium nucleatum (Fn), Campylobacter rectus (Cr), Peptostreptococcus anaerobius (Pa), and Eikenella corrodens (Ec) were analyzed using real-time polymerase chain reaction. Results: The detection frequencies of all pathogens, except Aa, were high in the PH and SPT groups. The ranking order of pathogen DNA copy numbers was similar in both groups. In both groups, Fn had the highest abundance, Aa had the lowest abundance. Additionally, Td was significantly more abundant in men than in women in both groups (P<0.05). Compared with the PH group, the SPT group exhibited significantly lower total bacteria and Fn abundance and higher Pg abundance (P<0.05). The age-specific pathogen distribution analysis revealed a significantly low Aa abundance and high Tf and Cr abundance in the PH group. Conclusions: The clinical parameters and microbial profiles were similar between the SPT and PH groups. However, patients with periodontitis require supportive care to prevent recurrence. As the abundance of some bacteria varied with age, future studies must elucidate the correlation between age-related physiological changes and periodontal bacterial composition.

Background: Surgical and non-surgical periodontal procedures often lead to postoperative pain. Clinicians use pharmacological methods such as anesthetics, anti-inflammatory drugs, and analgesics for relief. However, the multitude of options makes it challenging to select the best approach for routine dental care. Objective: This review aimed to describe previous studies regarding the pharmacological management used for pain control during periodontal procedures as well as factors that may interfere with patients' perception of pain. Methods: We included studies (period of 2000-2023, whose approach corresponded to the pharmacological protocols used for preoperative, trans-operative, and postoperative pain control in adult patients undergoing surgical and non-surgical periodontal therapy. Results: A total of 32 studies were included in the analysis, of which 17 (53%) were related to anesthetic methods and 15 (47%) were related to therapeutic protocols (anti-inflammatory/analgesic agents). These studies predominantly involved nonsurgical periodontal procedures. Studies have reported that factors related to age, type of procedure, and anxiety can influence pain perception; however, only seven of these studies evaluated anxiety. Conclusions: Numerous methods for pain control can be applied in periodontal therapy, which are accomplished through anesthetic methods and/or therapeutic protocols. Factors such as anxiety, age, and type of procedure are related to pain perception in patients. Thus, it is the responsibility of dentists to evaluate each clinical situation and define the best protocol to follow based on the literature.

Objectives : The aim of this study was to analyze relationship between body mass index(BMI), oral health behavior, and perceived oral symptoms among child care teachers. Methods : The subjects were 310 child care teachers who worked in child care centers in Jeollabukdo Province, Korea. A cross tab analysis and a multiple regression analysis were conducted to find a possible relationship between oral health behavior, oral symptoms and BMI. Results : BMI in child care teachers was 35.1% and male and married teachers had higher BMI. Higher BMI revealed perceived periodontal disease in smokers. Higher BMI was closely related to perceived xerostomia and halitosis. Conclusions : BMI is a very important index to develop health improvement and obesity control.

Objectives: This study aimed to examine the association between age at menarche and two major oral diseases. Methods: Data from the 7th Korean National Health and Nutrition Examination Survey (2016-2018) were used. The participants included girls and women aged 12 years and above. Thedataofa total of 7,420 participants were analyzed. Statistical analyses were performed using complex samples cross-tabulation analysis and complex samples general linear model. Results: The average age at menarche of those aged 12 to 80 years was 13.81 years. The age at menarche was found to be associated with decayed-missing-filled teeth (DMFT) (p<0.05). When the age at menarche was nine years, DMFT was 4.20 when it was 19 years, DMFT was 10.80. The age at menarche was found to be associated with periodontal tissue state (p<0.05). The group with early menarche age had healthier periodontal tissues (17.1%), whereas the group with late menarche age had more unhealthy periodontal tissues (17.9%) (p<0.001). Conclusions: The age at menarche was associated with two major oral diseases. Therefore, it is necessary to provide women with oral hygiene care and oral health education to prevent major oral diseases before their secondary sex characteristics appear.

만성적인 염증이 다단계 발암과정에서 다면적인 역할을 하고 있음은 이미 잘 알려진 사실이다. 치주 질환의 원인은 구강 박테리아에서 분비되는 내독소들과 염증 유발인자들의 생성 등이 관여하는 다양한 요인들을 포함하며, 이는 잘못된 구강 위생 관리가 신체의 여러 가지 전신병적 원인과 연관되어 있음을 의미한다. 비위생적인 구강 상태와 연관된 만성 염증, 흡연, 알콜 섭취의 증가 등은 암의 발병 위험 요소로 작용함은 명확한 사실이다. 최근에는 구강 위생과 치아 손실이 위장관암, 폐암 및 췌장암 뿐만 아니라 혈구암 발병 증가와 직접적인 연관성이 있음이 밝혀졌다. 또한 흡연은 악성 질환 발병의 위험 요소로서 구강 위생의 강력한 위해요인임은 명백하며, 역학적 조사결과들에 의하면 구강 박테리아에 의한 치주 질환은 만성 염증을 통하여 흡연과 알콜 연관 발암원을 활성시킴으로서 다양한 암의 발병 위험 요소를 증가시킬 수 있는 것으로 나타났다. 따라서 암 뿐만 아니라 다른 다양한 질환의 예방을 위한 적절한 구강 관리는 필수적이다. 본 논문에서는 암예방을 위한 악성질환의 위해 요소로서 염증과 치주질환 및 구강 위생과의 연관성을 논하였다.
