This study assessed the effect of triweekly interdental brushing for a period of 6 months using the bleeding on full-mouth interdental brushing (BOFIB) index. All participants answered questionnaires and were instructed to clean all interdental areas using an interdental brush at least every second day. A dentist assessed the BOFIB index of 28 participants at baseline and at 3- and 6-month follow-up visits. We stratified the participants into three groups: IB-NN, those who used the interdental brush less than three times per week both before and after this program; IB-NY, those who used the interdental brush less than three times per week before the program but at least three times per week after the program; and IB-YY, those who used it at least three times per week both before and after the program. Owing to the weekly number of interdental brushings, the IB-YY and the other two groups showed a significant difference at baseline. At the 6-month follow-up, the weekly number of interdental brushings led to a significant difference between the IB-NN and the other two groups. The BOFIB index was lower among the compliant participants than among the noncompliant participants after 3 and 6 months of triweekly interdental brushing.

This study aimed to evaluate the long-term impact of children’s dental care programs on children and adolescents to reduce oral health inequalities. It measured and assessed the improvement effects of children’s dental care programs on the oral health of children and adolescents as part of the efforts to decrease oral health disparities in this age group. It included 406 individuals who participated in student and children’s dental care program between 2013 and 2019 at screening facilities in Gwangjin-gu, Seoul. A frequency analysis was conducted for demographic characteristics, and a binary logistic regression analysis was performed to identify factors influencing the prevalence of dental caries as the dependent variable. The data were analyzed using PASW Statistics with the statistical significance level set at α = 0.05. Regarding oral health status based on the frequency of participation in children’s dental care program for children and adolescents, participants with seven or more sessions had lower prevalence rates of dental caries, malocclusion, and periodontal disease than those with only one session. Second, when comparing oral health status in children’s dental care program between primary and adolescent age groups, individuals under continuous oral health care showed a decrease in permanent teeth affected by dental caries, dental caries prevalence, and malocclusion prevalence (excluding primary school age). Third, a binary logistic regression analysis revealed significant influences (p < 0.05) of the developmental stage and frequency of program participation on dental caries prevalence. Children’s dental care programs are essential for alleviating oral health inequalities among children and adolescents and preventing oral diseases. Furthermore, the developmental stage of children and the frequency of program participation are crucial factors in preventing oral conditions, such as dental caries.

(1) Background: To analyze the association between periodontal health status and daily oral health activities including lingual and palatal site toothbrushing. (2) Methods: One hundred and fifty Korean elderly people aged >65 years participated in the study. Clinical examination regarding oral health status, including periodontal health status, was evaluated, and data on the oral health activities, socio-demographic factors, and systemic health-related factors were obtained using a questionnaire. Statistical analyses assessed the differences of periodontal health status according to daily oral health activities, including lingual and palatal site toothbrushing. (3) Results: Oral health activities including lingual and palatal site toothbrushing, frequency of toothbrushing, use of an interdental toothbrush, dietary patterns, and activity dependence correlated with bleeding on probing (BOP) and periodontitis. After adjusting for covariates, the prevalence of periodontitis was lower in the group where the inner surfaces of the teeth were partially or wholly cleaned than in the group without such cleaning. High BOP was significantly associated with the brushing of the inner surfaces of teeth. (4) Conclusions: Lingual and palatal site toothbrushing was associated with good periodontal health status in the elderly; the importance of brushing the inner surfaces of teeth should be emphasized for them and their caregivers.
