The effectiveness of novel remineralising agents in white spot lesion treatment after microabrasion.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIn clinical practice, microabrasion and remineralising agents, or their combinations, could be effective for white spot lesions (WSL) treatment. This study evaluates the effectiveness of four treatments, including two novel remineralising agents, nanohydroxyapatite (nanoHAP) and calcium glycerophosphate (CaGP) in combination with/without microabrasion on WSL.
methodsArtificially created WSL on human enamels were randomly divided into nine groups according to treatments: (1) Group FV/fluoride varnish (Bifluoride 10); (2) Group NanoHAP/nanohydroxyapatite gel (Biodent); (3) Group CaGP/calcium glycerophosphate gel (SPC Kozmetik); (4) Group ICON/resin infiltration (ICON); (5) Group Micro/microabrasion (Opalustre); (6) Group Micro + FV/microabrasion + fluoride varnish; (7) Group Micro + NanoHAP/ microabrasion + nanohydroxyapatite gel; (8) Group Micro + CaGP/microabrasion + calcium-glycerophosphate gel; (9) Group Micro + ICON/microabrasion + resin infiltration. Samples were analysed using a Vickers microhardness (VHN) testing and two fluorescence-based methods (FluoreCam and DIAGNOdent Pen/DDPen) at baseline, after demineralisation and after treatment(n = 10). SEM/EDS was used for the evaluation of surface morphology and elemental analyses (n = 5). The data were statistically analysed (p < 0.05).
resultsAfter treatments, Groups NanoHAP and Micro + NanoHAP showed significantly higher increases in VHN than Groups CaGP, Micro, ICON, Micro + ICON, and Micro + CaGP (p < 0.05). According to the DDPen score, Group NanoHAP showed significantly higher remineralising potential than Groups CaGP, ICON, and Micro + ICON (p < 0.05). According to FluoreCam data, a significantly higher remineralising effect was determined for Group Micro + NanoHAP than Group ICON (p < 0.05). SEM analysis revealed that the deposition of a new mineralised layer was present for Groups NanoHAP and CaGP. EDS analysis detected that Groups NanoHAP and CaGP had similar Ca/P, Na, Cl, C, and O contents to Group FV (p > 0.05). Regarding the presence of microabrasion, no significant differences in VHN, DDPen, FluoreCam, and EDS results were found for NanoHAP- and CaGP-containing groups (p > 0.05).
conclusionsNovel remineralising agents nanoHAP and CaGP could provide promising results with nanoHAP showing superior potential, whereas microabrasion before remineralising agents did not produce a significant additional effect on WSL. CLINICAL RELEVANCE: NanoHAP is an effective alternative to fluoride for treating white spot lesions and may reduce the need for additional microabrasion procedures.
