Stress Response Pathways in Ameloblasts: Implications for Amelogenesis and Dental Fluorosis

open access: yesCells, 2012
Human enamel development of the permanent teeth takes place during childhood and stresses encountered during this period can have lasting effects on the appearance and structural integrity of the enamel.

Measuring fracture toughness of human dental enamel at small scale using notched microcantilever beams

open access: yesBiosurface and Biotribology, 2021
Dental enamel is the most mineralised hard tissue with a complex hierarchically organised anisotropic structure and it protects human teeth from mechanical damage during the dental function.

Translucency of Human Dental Enamel [PDF]

open access: yesJournal of Dental Research, 1981
Translucency of human dental enamel was determined by total transmittance of wavelengths from 400 to 700 nm. The transmission coefficient at 525 nm was 0.481 mm -1 . Total transmission of light through human dental enamel increased with increasing wavelength.

Dental enamel, fluorosis and amoxicillin

open access: yesLa Pediatria Medica e Chirurgica, 2012
Amoxicillin is one of the most used antibiotics among pediatric patients for the treatment of upper respiratory tract infections and specially for acute otitis media (AOM), a common diseases of infants and childhood. It has been speculated that the use of amoxicillin during early childhood could be associated with dental enamel fluorosis, also ...

Proteinases in Developing Dental Enamel [PDF]

open access: yesCritical Reviews in Oral Biology & Medicine, 1999
For almost three decades, proteinases have been known to reside within developing dental enamel. However, identification and characterization of these proteinases have been slow and difficult, because they are present in very small quantities and they are difficult to purify directly from the mineralizing enamel.

Evaluation of the Effects of Residual Resin Removal and Polishing on the Enamel Surface, after Bracket Debonding

open access: yesRevista Naval de Odontologia On Line, 2023
Considering the use of specific burs to remove residual resin after bracket debonding and the possibility of injuries to the dental enamel after using these burs, this study aimed to verify the variation in the enamel surface appearance in a qualitative ...

High-resolution Raman spectroscopy reveals compositional differences between pigmented incisor enamel and unpigmented molar enamel in Rattus norvegicus

open access: yesScientific Reports, 2023
Dental enamel is a peculiar biological tissue devoid of any self-renewal capacity as opposed to bone. Thus, a thorough understanding of enamel composition is essential to develop novel strategies for dental enamel repair.
