Reduction of hsCRP levels following an Oral Health Education Program combined with routine dental treatment.

OBJECTIVES: The present study aimed to determine the effect of a personalised oral health education program, in combination with routine dental treatment, on serum biomarkers of systemic disease compared to dental treatment alone in a population from a low-socioeconomic community with poor oral health. METHODS: This secondary analysis of a randomised clinical trial involved 295 participants (mean age, 45.4 ± 11 years) assigned to two groups. One group received dental treatment combined with the Oral Health Education Program (OHEPDT), while the second group (DT) received dental care without the Education Program. Serum levels of high-sensitivity C-reactive protein (hsCRP), lipid profile (total cholesterol, triglycerides, and high- and low-density lipoprotein cholesterol), and HbA1c levels were analysed at baseline and after 12 months. Changes in diet, smoking and alcohol consumption were also determined. RESULTS: No intergroup differences were observed for the lipid profile and HbA1c levels. A reduction in the hsCRP levels at the 12-month follow-up was observed in the OHEPDT group, which was significantly different from the DT group (p = 0.01). Multivariate modelling indicated that baseline hsCRP levels (p = 0.000), baseline body mass index (p = 0.000), and higher consumption of vegetables (p = 0.021) predicted a reduction in hsCRP levels. CONCLUSIONS: This study demonstrated that personalised oral health education combined with routine dental treatment was associated with a significant reduction in hsCRP levels subsequent to dietary behavioural changes. These findings suggest that personalised oral health education in combined with routine dental treatment may have beneficial effects on general health. CLINICAL SIGNIFICANCE: The strategy for developing an oral health program that involves education of the modifiable common risk factors for general health has beneficial effects and should be one of the priority components of these programs to improve oral and general health, particularly for at-risk communities.

The Effect of a Personalized Oral Health Education Program on Periodontal Health in an At-Risk Population: A Randomized Controlled Trial.

While periodontal disease is associated with many risk factors, socioeconomically disadvantaged communities experience the highest disease burden. The aim of this study was to evaluate the effectiveness of a personalized oral health education program, in combination with routine dental treatment, in participants from a low socioeconomic community. We used a randomized, controlled, examiner-blinded clinical trial. A total of 579 participants (aged 18-60 years) were randomly grouped: the intervention group (n = 292) received a personalized oral health education program in combination with routine dental care and the control group (n = 287) received routine dental care. All participants were assessed for improvement in oral health care behaviors, dental plaque, and periodontal status at baseline, 12 months, and 24 months. We found a significant drop (p < 0.001) in the plaque indices, Periodontal Probing Depths (PPD) and Bleeding on Probing (BOP) between baseline and the 12-month follow-up for both groups. For BOP, the number of sites positive was significantly different between baseline and the 24-month follow-up (p = 0.037). No differences were found between the two groups for any evaluated clinical outcome. The personalized oral health education program used in the current study did not appear to add significant improvement to clinical outcomes of periodontal health compared with routine restorative dental care per se.

Effect of Probiotic Lactobacillus reuteri on Salivary Cariogenic Bacterial Counts among Groups of Preschool Children in Jeddah, Saudi Arabia: A Randomized Clinical Trial.

OBJECTIVES: To evaluate the effect of probiotic Lactobacilli reuteri lozenges on caries-associated salivary bacterial counts (Mutans streptococci and Lactobacillus), dental plaque accumulation, and salivary buffer capacity in a group of preschool children. STUDY DESIGN: The study group consisted of 178 healthy children (aged 3-6 years). Children were randomly grouped: the experimental group (n = 90) received L. reuteri probiotic lozenges and the control group (n = 88) received placebo lozenges, twice daily, for 28 days. Salivary Mutans streptococci and Lactobacillus counts, and buffer capacity were assessed using chair-side caries-risk test (CRT®) kits. The Simplified Oral Hygiene index (OHI-S) was used to assess dental plaque accumulation at baseline and after 28 days. RESULTS: After 28 days, the experimental group had a statistically significant reduction in Mutans streptococci and lactobacilli (p = 0.000 and p = 0.020, respectively) and both groups had less plaque accumulation than at baseline. While the buffer capacity in the experimental group increased more than in the control group, it was not statistically significant (p = 0.577). Compliance was 90%, with no adverse events. CONCLUSIONS: Consumption of probiotic lozenges containing L. reuteri reduces caries-associated bacterial counts significantly. Probiotics consumption may have a beneficial caries-preventive effect.
