Background and Objective: Dental fluorosis is a disease affecting dental hard tissues featured with white or yellowish lesions. Several treatments are proposed in the literature, some even invasive. This clinical study aimed to evaluate the effectiveness of resin infiltration in terms of lesions resolution, trend of sensitive teeth and satisfaction of patients over time. Methods and Material: 200 fluorosis lesions were treated using ICON infiltrating resin (DMG, Hamburg, Germany). Parameters related to patients were collected by a questionnaire and analyzed aesthetic dissatisfaction about lesions, Shiff Air Index Sensitive Scale, sensitive teeth after treatment, the satisfaction of duration of treatment. The same operator measured dimensions of lesions Tooth Surface Index of Fluorosis (TSIF) and numbers of etching cycles needed for treating lesions. Statistical analysis was performed. The follow-up was of 1-year a measurement were performed at baseline (t0), immediately after the treatment (t1) and every three months during the observation period. Results: All lesions disappeared after one treatment. Pain or sensitive teeth were reported inside the 72 h and they disappeared after. Statistical analysis showed highly statistically correlation between etching cycles and the dimension of lesions and TSIF at the time-points evaluated as well as for pain during treatment, whereas a statistical significance was not noticed where etching cycles were correlated to sensitive teeth after 72 h. Overall, the treatment was found to be statistically significantly associated with differences in answers of aesthetic dissatisfaction between t0 and t1 and those collected between t1 and t2. Between t2 and t3 and between t3 and t4 no statistical differences were found in answers of patients about dissatisfaction, indicating the stability of the results. Conclusions: The ICON resin infiltration technique was found to be effective in lesions resolution with steady results.

An Evaluation of the Demineralizing Effects of Various Acidic Solutions

et al. 2021

The purpose of this study was to evaluate which of the techniques and acids included in this in vitro research can induce artificial caries lesions in the most natural way. White spot lesions were created using six different demineralizing solutions in liquid form (lactic acid; orthophosphoric acid; formic acid; and an acid solution that contains calcium chloride, sodium phosphate and acetic acid) and gel form (hydrochloric acid and orthophosphoric acid). Radiographs, photographs and readings with a DIAGNODent™ pen, VITA Easyshade and a scanning electron microscope (SEM) were made in the initial situation, after 30 min, 1 h, 24 h and 96 h of demineralization. The total color change (ΔE) values in most cases presented statistically significant differences. SEM images showed different aspects of the enamel surface for each type of acid. Only in the case of exposed dentine did the DIAGNODent™ pen record significant differences. There was no noticeable radio-translucency of the teeth treated for a short period of time, but after 24 h, the absence of enamel and major demineralization of dentine were visible. Acids in the liquid state can penetrate and demineralize dental structures deeper than those that are more viscous. This study should be repeated with a protocol that includes remineralization. Using weaker acids would be another direction that could lead to more interesting findings.

The aim of this in vitro study was to compare the remineralization efficiency among Nano-silver fluoride 400 ppm (NSF400), 38% Silver diamine fluoride (38% SDF) and 5% Sodium fluoride (5% NaF) on artificial dentine caries in permanent molar or premolar teeth. The teeth were sectioned to obtain 120 specimens (3 x 3 x 2 mm3). After artificial caries were created, the lesion depth (LD) was measured using Micro-computed tomography (Micro-CT) (n=15 specimens/group), and the surface microhardness (SMH) was measured using a Knoop microhardness tester (n=15 specimens/group). Subsequently, all specimens were randomly assigned to four groups: Group 1) NSF400, Group 2) 38% SDF, Group 3) 5% NaF, and Group 4) Deionized water (control group). Experimental treatments were applied. All specimens were immersed in culture media containing Streptococcus mutans and Candida albicans for 24 hours to create a biofilm and underwent a biofilm pH-cycling for 7 days. The measurements of lesion depth and surface microhardness were conducted after the treatment. The results before and after treatment were compared using the paired t-test. Then, the mean percentage change in lesion depth (%LD change) and the mean percentage of surface microhardness recovery (%SHR) among the groups were compared using One-way ANOVA with Tukey's post hoc test (p<0.05). The results showed that after treatment, Groups 1 and 2 had a significant decrease in mean LD, while Groups 1, 2, and 3 exhibited a significant increase in mean SMH compared to their pre-treatment values. The %LD change in Groups 1, 2, 3, and 4 were -7.80 ? 3.70, -12.69 ? 4.66, 1.66 ? 4.80, and 8.34 ? 3.62, respectively. Group 1 exhibited a significant decrease in %LD change compared to groups 3 and 4 (p<0.001), but it was significantly lower than group 2 (p=0.013). The %SHR of groups 1, 2, 3, and 4 were 7.86 ? 3.15, 10.49 ? 1.82, 1.60 ? 1.52, and -1.44 ? 0.79 respectively. Group 1 exhibited a significantly higher %SHR compared to groups 3 and 4 but it was lower than group 2 (p<0.001). In conclusion, the Nano-silver fluoride 5provided remineralization effects on artificial dentine caries better than 5% Sodium fluoride varnish but not as effectively as 38% Silver diamine fluoride.
