Type 1 diabetes mellitus effects on dental enamel formation revealed by microscopy and microanalysis.
Silva BLL, et al. J Oral Pathol Med 2018. PMID 29243281
T1DM also caused important ultrastructural alterations in mature enamel as revealed by SEM and induced a statistically significant reduction of about 13.67% in its microhardness at 80 μm from dentin-enamel junction (P < .01). CONCLUSIONS: This study shows that T1DM may disturb enamel development, leading to alterations in mature enamel ultrastructure and in its mechanical features....

Sea otter dental enamel is highly resistant to chipping due to its microstructure.
Ziscovici C, et al. Biol Lett 2014. PMID 25319817 Free PMC article.
Dental enamel is prone to damage by chipping with large hard objects at forces that depend on chip size and enamel toughness. ...Here, we show that equivalent chips in sea otter enamel require even higher forces than human enamel. Increased fracture resistance correlates with more intense enamel prism decussation, often seen also in some fossil hominins. ...

A comparative study on component volumes from outer to inner dental enamel in relation to enamel tufts.
Setally Azevedo Macena M, et al. Arch Oral Biol 2014. PMID 24685496
BACKGROUND AND AIM: Dental enamel presents marked mechanical properties gradients from outer to inner enamel, a region lacking component volumes profiles. Tufts, structures of inner enamel, have been shown to play a role in enamel resilience. We aimed at comparing component volumes from inner to outer enamel in relation to enamel tufts. ...

Ultrastructure of spindles and tufts in human dental enamel.
Palamara J, et al. Adv Dent Res 1989. PMID 2640435
Spindles in human dental enamel were found to be continuous with dentinal tubules across the dentin-enamel junction (DEJ) and usually appeared at the DEJ as electron-lucent, empty channels nearly circular in cross-section. ...Two types of ultrastructure were observed in the TEM: (i) disrupted regions of enamel incorporating large voids (up to approximately 0.1 microns in diameter), or, more commonly, (ii) channels within the enamel occluded or partially occluded, with small needle-like crystals and granular and/or amorphous material similar to that found in the enamel spindles. ...

Effects of continuous-wave CO2 laser on the ultrastructure of human dental enamel.
Ferreira JM, et al. Arch Oral Biol 1989. PMID 2512902
The crazed and cratered enamel had significant ultrastructural changes: new homogeneous and inhomogeneous crystals of apatite with a different shape and larger size than those of the original, and a loss of prismatic structure. ...The crazing, crazing and cratering, rough exposed enamel and the greater number of voids, as well as the relative softness of lased enamel do not indicate an overall ultrastructural improvement. ...

Ultrastructure and composition of enamel in human dental fluorosis.
Yanagisawa T, et al. Adv Dent Res 1989. PMID 2640431
Enamel surfaces were generally cloudy to opaque, with several pits or defects of various sizes and degrees of brown-staining. An extensively hypomineralized area extended from the inner enamel to the surface layer, which was mineralized to a high degree. ...

Morphological changes produced by acid dissolution in Er:YAG laser irradiated dental enamel.
Manuela Díaz-Monroy J, et al. Microsc Res Tech 2014. PMID 24659325
The aim of this study was to evaluate the morphological changes produced by acid dissolution in Er:YAG laser irradiated dental enamel. ...Morphological changes produced by acid dissolution of irradiated enamel were observed, specifically on laser-induced undesired effects. ...

Atomic force microscopy analysis of enamel nanotopography after interproximal reduction.
Meredith L, et al. Am J Orthod Dentofacial Orthop 2017. PMID 28364899
The enamel surfaces were assessed using atomic force microscopy. RESULTS: The IPR instruments all produced surfaces rougher than the control sample; however, the samples that received polishing with Sof-Lex discs after enamel reduction were smoother than untreated enamel (P <0.05 for all comparisons). ...Polishing with Sof-Lex polishing discs after IPR reduced the enamel surface roughness, and this surface was even smoother than untreated enamel....

Qualitative and quantitative evaluation of human dental enamel after bracket debonding: a noncontact three-dimensional optical profilometry analysis.
Ferreira FG, et al. Clin Oral Investig 2014. PMID 24327234
Enamel loss was minimal. CONCLUSIONS: The 3D optical profilometry technique was able to provide accurate qualitative and quantitative assessment of changes on the enamel surface after debonding. CLINICAL RELEVANCE: Morphological changes in the topography of dental surfaces, especially if related to enamel loss and roughness, are of considerable clinical importance. ...

[Ultrastructure of conditioned enamel surfaces and their adhesive matrices in dental enamel sealing].
Vahl J and Wosiewitz U. Dtsch Zahnarztl Z 1976. PMID 1060562 German.
The enamel sealant Nuva Seal was tested in model tests on caries-free human molars and premolars. Under the scanning electron microscope the acid-etched enamel areas (natural and ground surfaces) and the corresponding Nuva Seal matrices were studied. ...Peg-shaped elevations 10-20 mum in size that can sometimes be observed in the Nuva Seal impressions are interpreted as representing enamel defects....
