    A quantitative comparison of oral microbiota using various sample collection methods: a pilot study

    Sang-Uk Im , Ji-Hye Kim , Keun-Bae Song , Youn-Hee Choi

    Abstract : Objectives: This study aimed to compare each strain’s number of microorganisms found in oral samples collected using various collection methods. Methods: Twenty-two adults aged 40 and above participated in the study. Oral samples were collected from subjects using three different methods (stimulated saliva, oral biofilm, and calculus), and the collected samples were analyzed using the multiplex real-time Polymerase chain reaction (PCR) method. Results: The study included 22 subjects (2 men, 20 women) with an age range of 40-75 years. Healthy oral condition was observed in 10 subjects, while the remaining 12 had periodontitis. The saliva and biofilm collection methods for oral microorganisms detected Porphyromonas gingivalis (Pg), Tannerella forsynthesis (Tf), and Fusobacterium nucleatum (Fn), which are the causative bacteria of periodontal disease, more effectively compared with the calculus group. In addition, the saliva group showed a better ability to detect Streptococcus mutans (Sm) which causes dental caries, compared with the biofilm and calculus groups. Comparisons based on the presence or absence of periodontitis and the collection method revealed a statistically significant difference in the number of oral microorganisms only in case of Sm strain. Conclusions: The frequency of expression of certain strains varies according to the method of collection of oral microorganisms. Further, the saliva and biofilm methods of collecting oral microorganisms are more suitable for quantitative analysis of bacteria causing periodontal disease.

    Risk factors for dental caries and severe periodontitis in Korean adults: analysis with the 2016-2018 Korea National Health and Nutrition Examination Survey data

    Se-Hwan Jung

    Abstract : Objectives: The purpose of this study was to analyze the risk factors for dental caries and severe periodontitis using the data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES) for improving the lifestyle risk assessment and oral health education in national adult dental examination program. Methods: The participants included 7,301 adults aged 19-59 years for dental caries analysis and 4,886 adults aged 40-59 years for severe periodontitis analysis. Self-care of oral hygiene (brushing teeth frequency, brushing teeth before bed, use of interdental brush or floss), sugar intake, and smoking were selected as risk factors related to oral health. The other risk factors included socio-demographic characteristics (age, gender, region, household income, education), dental care utilization (dental examination, unmet dental needs), and systematic diseases (hypertension, diabetes, high cholesterol). The association between the target diseases and risk factors was analyzed using a complex samples logistic regression model. Results: Dental caries was negatively associated with brushing teeth frequency, interdental brushing or flossing, sugar intake, and age; and positively associated with smoking and oral examination. Severe periodontitis was positively associated with smoking, diabetes, age, and region (eup/myeon). Gender (male), household income (low), and unmet dental care (yes) were positively associated with dental caries or severe periodontitis. Conclusions: It was possible to obtain evidence of lifestyle factors (self-care oral hygiene, sugar intake, smoking) affecting the target disease (dental caries or periodontal disease) for the national adult dental examination program. However, there were limitations in estimating causality as this was a cross-sectional study, and the explanatory power of the risk model was low. Therefore, it is necessary to conduct a cohort study of the adult dental examination program to obtain a higher level of evidence on the risk factors of the target diseases.
