Demineralization of Camel Dentin for Dental Tissue Engineering.
Article in International dental journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundDemineralisation of dentin effectively removes the crystalline hydroxyapatite phase while preserving the collagen matrix and associated bioactive proteins. This process results in an osteoinductive scaffold with favourable biological properties, making demineralised dentin a promising naturally derived biomaterial for dentoalveolar bone and orthopaedic bone tissue regeneration.
objectiveThis study aimed to evaluate the structural and elemental characteristics of camel dentin matrix after demineralisation using ethylenediaminetetraacetic acid (EDTA) and citric acid (CA) at various concentrations at 24 hours, with the goal of assessing its suitability as a biomaterial for bone grafting.
methodsCamel dentin granules were extracted after removal of enamel and cementum and treated with EDTA and citric acid for 24 hours. Post-treatment, samples were analysed using scanning electron microscopy to assess morphological changes, energy-dispersive X-ray spectroscopy for elemental composition, Fourier-transform infrared spectroscopy and Raman spectroscopy for molecular characterisation. The degree of demineralisation was compared across groups.
resultsScanning electron microscopy analysis revealed increased porosity and surface roughness following acid treatment, indicating demineralisation. Energy-dispersive X-ray spectroscopy analysis demonstrated a significant reduction in calcium and phosphorus levels, confirming mineral loss. Fourier-transform infrared spectra confirmed efficient demineralisation, evidenced by reduced phosphate and carbonate bands and enhanced Amide I to III peaks, indicating increased exposure of the collagen framework. Raman spectra showed diminished intensity of phosphate and carbonate peaks in treated samples, further supporting successful demineralisation. EDTA treatment for 24 hours yielded the most pronounced structural and chemical alterations.
conclusionDemineralisation of camel dentin using EDTA and citric acid effectively alters its morphology and elemental composition. The optimised demineralisation protocol provides a promising approach for developing future demineralised dentin-derived graft materials from animal sources with potential osteoinductive properties.
