The primary aim of this work is to present the available evidence that toothpastes containing >1,500 ppm fluoride (2,500-2,800 and 5,000 ppm F) provide an additional caries preventive effect on root caries lesions in elderly patients compared to traditional dentifrices (1,000-1,450 ppm F). The secondary aim of this paper is to discuss why high fluoride dentifrices in general should perform better than traditional F-containing toothpaste. When examining the few studies that have considered the preventive benefits of high fluoride products on root caries the relative risk appears to be around 0.5, and the risk can thus be halved by exchanging traditional F-containing toothpaste for toothpaste containing 5,000 ppm F. There is reasonable evidence that high fluoride dentifrices significantly increase the fluoride concentration in saliva during the day and the fluoride concentration in plaque compared to traditional F toothpaste. Furthermore, the use of toothpaste with 5,000 ppm F significantly reduces the amount of plaque accumulated, decreases the number of mutans streptococci and lactobacilli and possibly promotes calcium fluoride deposits to a higher degree than after the use of traditional F-containing toothpaste.

Teeth prepared as overdenture abutments are susceptible to caries, and it has been shown that brushing by itself is not sufficient to prevent this process. This study evaluated the preventive effect of a remineralization gel which has a low fluoride concentration and compared its effects with those of a phosphate fluoride gel (Karigel), which has a much higher concentration of fluoride. Twenty extracted anterior teeth from patients aged 50 to 70 years were prepared as for overdenture abutments. Each tooth was sectioned into three fragments. An acidified gel system was used to produce artificial caries lesions on the occlusal and root surfaces of each fragment. One fragment of each tooth was treated with the remineralizing gel, the second fragment with a high-fluoride gel, and the third fragment served as the control. Ten teeth were removed at two weeks and again at four weeks, and were sectioned and prepared for histological examination. The depth of the lesions was measured from standardized photomicrographs by means of a sonic digitizer. The conclusions were: (1) Lesions on the occlusal tended to be deeper than those on the root surfaces at four weeks but not at two weeks; and (2) the high-fluoride gel was more protective than the low-fluoride remineralizing solution at both time periods on the occlusal but not on the root surface.

Abstract This parallel, triple-blind RCT evaluated the restorative performance of a resin-modified glass-ionomer-cement (RMGIC) in irradiated patients and the prevention of root caries lesions adjacent to restoration, comparing the effect of conventional (control) concentration, high-fluoride (F) containing fTCP and arginine-based toothpastes. A total of 63 lesions was screened and 60 were included into randomized distribution into three groups (N- participants in baseline/n- root caries lesions): G1 = 1,450 ppm F (N = 10/n = 17); G2 = 5,000 ppm F + fTCP (N = 7/n = 18) and G3 = 1,450 ppm F + arginine + CaCO3 (N = 6/n = 25). Based on eligibility criteria, all patients were mandatory enrolled after completed 3-month of radiotherapy of head-and-neck. Two calibrated operators performed the restorative procedures (RMGIC - Vitremer) and two calibrated examiners (Kappa = 0.94) evaluated the restorations based on modified USPHS criteria at baseline, 1, 3 and 6-month follow-up. Data was collected and statistically assessed with Kruskal-Wallis test (p < 0.05). There were no statistically significance differences among the performance of the restoration among the three groups regarding the criteria retention, marginal adaptation, marginal staining, post-operative sensitivity, adjacent caries, color alteration, anatomic form and surface texture (p > 0.05). Even with oral complications caused by radiation-therapy, if the restorations are properly performed and patients are under professional supervision, high-F presented similar efficacy of arginine and conventional-containing toothpastes to prevent secondary caries. Clinical relevance: This clinical trial brings new evidences about the regular use of high-F, arginine-based and conventional-F containing toothpastes in irradiated patients under supervision of a multidisciplinary team and the encouragement of self-cooperation.

High fluoride dentifrice (FD; 5,000 ppm F) has been recommended to arrest root dentine lesions and to control enamel caries in high-risk patients. Also, standard FD (1,100 ppm F) in combination with professional fluoride application has been recommended to control dentine caries, but the effect of this combination on enamel has been considered modest. Considering the lack of evaluation comparing the use of 5,000 ppm FD (5,000-FD) versus acidulated phosphate fluoride (APF) application combined with 1,100 ppm FD (1,100-FD) on the inhibition and repair of caries lesions in both enamel and dentine, we conducted this in situ, double-blind, crossover study of 3 phases of 14 days. In each phase, 18 volunteers wore palatal appliances containing enamel and root dentine specimens, either sound or carious, to evaluate the effect of the treatments on the inhibition or repair of caries lesions, respectively. The treatments were non-FD (negative control), 5,000-FD, or 1 APF gel application on dental specimens combined with 1,100-FD used twice per day (APF + 1,100-FD). The reduction of demineralization and enhancement of remineralization were assessed by surface and cross-sectional hardness. Fluoride concentration was determined on dental specimens and on the formed biofilm. For enamel, APF + 1,100-FD and 5,000-FD did not differ regarding the inhibition of demineralization and repair of caries lesions. However, for dentine the difference between these treatments was inconclusive because while APF + 1,100-FD was more effective than 5,000-FD in caries lesion reduction and repair, 5,000-FD was more effective than APF + 1,100-FD in the reduction of surface demineralization. Therefore, the findings show that the combination of APF + 1,100-FD is as effective as 5,000-FD in enamel inhibition of demineralization and enhancement of remineralization.

Background and objectives: Knowledge of the pathogenicity of the primary etiological factor of root caries, the microbial biofilm, might provide important information for the development of diagnosis and treatment strategies. This study assessed the numbers and revealed the proportion of Mutans streptococci , which is potential important cariogenic organisms, in biofilms collected from lesions at root surfaces with active caries lesions (ARC), inactive caries lesions, and sound root surfaces (SRS). Material and methods: Samples were cultured in MSB agar for Mutans streptococci counts, and brain-heart infusion agar for total viable anaerobic counts. After incubation, the number of colony-forming units (CFUs) was determined and compared between groups by the Mann-Whitney U test with a significance level set at 95%. The proportion of counts of Mutans streptococci in the total viable microorganisms was also analyzed by Chi-square test. 108 samples (36 from each surface) from 36 patients were cultured and analyzed. Results: The mean±SD for the counts of active root caries lesions was 7.47±9.89 10, significantly higher than that of inactive root caries lesions (2.5±0.97) and sound root surfaces (3.03±0.71). In conclusion, a trend towards higher counts was evident for ARC. In the ARC lesions among the dominant oral anaerobic bacteria, we could not identify streptococcal colonies (unspecified) in 11% while in IRC lesions it occurred in 47%, and SRS it occurred in 47%. In addition, in ARC the samples were ≥0.1-≥10 (CFU x10) ≥0.1-≥10 colonies of Streptococcus mutans. Conclusion: In conclusion, a trend towards higher counts was evident for ARC and for most samples, the proportion of Streptococcus mutans was low relative to the viable number of total viable anaerobic microorganisms.                   Peer Review History: Received: 5 September 2021; Revised: 10 October; Accepted: 24 October, Available online: 15 November 2021 Academic Editor:  Ahmad Najib, Universitas Muslim Indonesia,  Indones UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.
