The effect of nano silver fluoride, self-assembling peptide and sodium fluoride varnish on salivary cariogenic bacteria: a randomized controlled clinical trial.

ABSTRACT:

Objectives

To compare the antibacterial effect of Nanosilver Fluoride varnish (NSF) varnish, P11-4 and Sodium Fluoride (NaF) varnish against salivary Streptococcus mutans (S. mutans) and Lactobacilli.

Methods

66 patients aged 10-24 years old were randomly assigned to receive single application of NSF, P11-4 or NaF varnish. Baseline unstimulated saliva samples were collected before the agents were applied and S.mutans and Lactobacilli colony forming units (CFU) were counted. After one, three and six months, microbiological samples were re-assessed. Groups were compared at each time point and changes across time were assessed. Multivariable linear regression compared the effect of P11-4 and NSF to NaF on salivary S. mutans and Lactobacilli log count at various follow up periods.

Results

There was a significant difference in salivary S. mutans log count after 1 month between P11-4 (B= -1.29, p = 0.049) and NaF but not at other time points nor between NSF and NaF at any time point. The significant reduction in bacterial counts lasted up to one month in all groups, to three months after using P11-4 and NaF and returned to baseline values after six months.

Conclusion

In general, the antimicrobial effect of P11-4 and NSF on salivary S. mutans and Lactobacilli was not significantly different from NaF varnish. P11-4 induced greater reduction more quickly than the two other agents and NSF antibacterial effect was lost after one month.

Clinical relevance

NSF varnish and P11-4 have antimicrobial activity that does not significantly differ from NaF by 3 months. P11-4 has the greatest antibacterial effect after one month with sustained effect till 3 months. The antibacterial effect of NSF lasts for one month. NaF remains effective till 3 months.

Project description:BackgroundEarly childhood caries (ECC) is the most prevalent chronic health problem in young children, and it can be arrested using professionally applied fluoride such as Sodium fluoride (NaF) varnish and Silver Diamine Fluoride (SDF). This trial compared two interventions to arrest ECC lesions: 38% SDF combined with 5% NaF varnish versus 38% SDF and assessed whether the arrest rate was affected by baseline lesion severity measured by ICDAS.MethodsChildren aged ≤ 4 years from 4 nurseries in a rural area in Alexandria, Egypt joined the study in March 2022. They were included if they had at least one active carious lesion with ICDAS codes ≥ 3. They were randomized to receive either 38% SDF with 5% NaF varnish or 38% SDF alone. In both groups, the agents were applied at baseline and after 6 months on the caries lesions. NaF was additionally applied on all teeth in the oral cavity, and it was also applied after three months. The primary outcome was lesion arrest status after six months. Parents' satisfaction with their children's appearance was the secondary outcome. Pearson Chi-Square test was used for bivariate comparison and multi-level multiple logistic regression was used to assess the effect of the intervention on caries arrest controlling for confounders. The interaction between the intervention and baseline lesion severity (categorized into moderate and severe lesions) was assessed and the p value was calculated.ResultsThe study included 1606 lesions in 220 children, median (IQR) age = 48(9) months. The percentages of arrested lesions after the application of SDF + NaF and SDF only were 77.7% and 73.2% (p = 0.035). In multivariable analysis, SDF + NaF had significantly greater caries arrest effect than SDF alone (AOR = 2.12, p = 0.03) with significant difference (p = 0.03) between moderate (AOR = 4.10, p = 0.005) and advanced (AOR = 1.92, p = 0.08) lesions. Most parents were satisfied with their children's appearance with no significant difference between groups (SDF + NaF = 84.5%, SDF = 78.18%, p = 0.23).ConclusionSDF + NaF had a higher arrest rate than SDF alone and this difference was significant in moderate but not advanced lesions. The findings have implications for the non-invasive management of ECC.Trial registrationThis trial was registered in the clinicaltrials.gov registry (#NCT05642494).

Project description:BackgroundSilver Diamine Fluoride (SDF) has gained attention as one of the minimally invasive modalities to manage ECC although it causes black staining of treated carious lesions. A possible affordable alternative may be Sodium Fluoride (NaF) varnish combined with good oral hygiene promoted by parental Motivational Interviewing (MI). The study compared the effectiveness of 38% SDF solution and 5% NaF varnish supported by parental MI in arresting ECC.Materials and methodsChildren aged ≤ 4 years old with at least one active carious lesion (ICDAS score ≥ 3) were randomly assigned to treatment by a single application of 38% SDF solution or a single application of 5% NaF varnish supported by two MI sessions for mothers at baseline and after three months. Chi-Squared test was used to compare groups and multilevel logistic regression analysis was used to assess the effect of the interventions on ECC arrest adjusting for confounders. The interaction between the type of intervention and baseline lesion severity, moderate (ICDAS 3/4) or advanced (ICDAS 5/6), was also assessed.ResultsThe study included 165 children with 949 active lesions. After 6 months, there were no significant differences between SDF and NaF/MI groups in overall caries arrest (63.7% and 58.1%, p = 0.08), and in moderate lesions (72.9% and 69.6%, p = 0.52). However, in advanced lesions, the arrest rate was significantly higher in the SDF than the NaF/ MI group (60.3% and 50.0%, P = 0.01). Multilevel multiple logistic regression showed no significant differences between the interventions (AOR = 1.56, P = 0.27) with significant interaction between the intervention and baseline lesion severity (p < 0.001). Moderate lesions treated with SDF (AOR = 3.69, P = 0.008) or NaF/MI (AOR = 3.32, P < 0.001) had significantly higher odds of arrest than advanced lesions treated with NaF/ MI with no difference between advanced lesions treated with SDF or NaF/ MI (AOR = 1.85, P = 0.155) in arrest rate.ConclusionNaF/ MI can be an alternative to SDF in arresting advanced and moderate ECC lesions without staining with stronger effect on moderate lesions (ICDAS 3/4).Trial registrationThe trial was retrospectively registered at clinicaltrial.gov registry (#NCT05761041) on 9/3/2023.
