|Abstract: ||The aim of this thesis was to address and investigate some of the main challenges in the fields of cariology and caries management.
In the first two Chapters, available literature on the formation and remineralisation of carious enamel lesions at different structural levels of enamel including microscopic tissue level, rod level and crystal level were reviewed.
In Chapter 3, an approach was developed to provide quantitative and qualitative information of the carious enamel lesions in a non-subjective manner based on x-ray micro computed tomography, image de-noising and visualisation techniques.
In chapter 4, a systematic study of natural fissural enamel lesions was performed using X-ray micro computed tomography and image processing methods revealing the exclusive pattern and quantifying the structural features of fissural lesions.
In Chapter 5, the study of natural brown spot enamel lesions revealed the different structure and mineral pattern of brown spot lesions compared to white spot enamel lesions. Two distinguishable shapes including reverse triangular and trapezoid were the common patterns in brown spot enamel lesions.
In Chapter 6 a method using high pressure homogenisation, for the preparation of hydroxyapatite nanoparticles, was developed and the efficacy of produced hydroxyapatite nanoparticles for remineralisation of artificial enamel lesions was evaluated.|
