PURPOSE: Fluoride is essential for protecting the teeth from dental caries. The combined use of lasers with fluoride is being explored to increase the fluoride uptake of the tooth after topical fluoride application. The present research aimed to assess the efficacy of diode laser irradiation in enhancing fluoride uptake in primary teeth enamel following topical fluoride application.
METHODS: A total of 14 primary teeth (70 enamel slabs) were selected for the study. From each primary tooth, five enamel slabs were made and were put randomly into five different groups, that is, group I: control (no treatment), group II: NaF varnish (sodium fluoride), group III: SDF (silver diamine fluoride), group IV: NaF varnish with laser irradiation, and group V: SDF with laser irradiation. NaF varnish (5%) and SDF (38%) were topically applied in groups II and III, respectively, without laser irradiation, while in groups IV and V diode laser was used following NaF varnish (5%) and SDF (38%) application, respectively. Fluoride content was measured in all groups using a scanning electron microscope and energy dispersive X-ray spectroscopy (SEM-EDX) analysis. Results were analyzed using the t-test and analysis of variance (ANOVA) test, followed by Bonferroni corrections.
RESULTS: Increased fluoride content was found in groups II, III, IV, and V in comparison to group I. Higher fluoride content was noted in NaF varnish with laser irradiation and SDF with laser irradiation groups in contrast to NaF varnish and SDF groups, respectively; however, the difference between NaF varnish and NaF varnish with laser irradiation groups as well as between SDF and SDF with laser irradiation groups was statistically insignificant (p < 0.05).
CONCLUSION: The SDF with laser application group was found to be the most effective in increasing the fluoride content of the enamel, and the sequence of effectiveness is as follows: SDF with laser application > SDF ≥ NaF with laser application > NaF > control. Therefore, more in vitro and in vivo studies need to be conducted to evaluate the combined use of lasers and topical fluoride.
