Clear aligner attachment removal techniques – an in vitro comparison of removal time residual composite, enamel surface characteristics, enamel loss, and material cost
… but can also produce iatrogenic effects to the enamel. Bracket adhesive removal has been thoroughly studied in the literature, commonly utilizing extracted human teeth as a close alternative to in vivo studies. Studies posit that the low speed (LS) fine carbide bur continues to be the most …

Evaluation of fluid transport processes in dental enamel. Methods to assess the relevance of enamel permeability in caries prevention and etching treatments.
This thesis evaluated in vivo and in vitro enamel permeability in different physiological and clinical conditions by means of SEM inspection of replicas of enamel surface obtained from polyvinyl siloxane impressions subsequently later cast in polyether impression ma-terial. This technique, not …

The Role of Enamel Matrix Protein Amelotin on Biomineralization
… process of tooth tissues. Dental enamel plays a crucial role in preventing the tooth from destruction. However, if damaged or lost, it cannot be regenerated. Understanding the molecular mechanisms behind formation of enamel would not only make restoration of the tissue possible, …

Λευκές κηλίδες της αδαμαντίνης (enamel opacities) εφηβικού πληθυσμού Ιορδανίας
THE EXISTENCE OF ENAMEL OPACITIES IS A VERY COMMON PHENOMENON IN THE PERMANENT DENTITION. THE AIM OF THIS INVESTIGATION WAS TO STUDY AND DETERMINE THE PREVALENCE AND SEVERITY CONCERNING THE NON-FLUORIDE ENAMEL OPACITIES IN THE YOUNG POPULATION (JORDANIANS AND PALESTINIANS) OF THE JORDANIAN JARASH. …

In Vitro Study Comparing Treatments for Incipient Enamel Lesion Remineralization
… Diamine Fluoride (SDF; Advantage Arrest™) on enamel surfaces affected by incipient caries lesions. Methods: Caries-free permanent teeth, extracted for orthodontic or surgical purposes, were obtained from the Pediatric Dentistry Department at UIC College of Dentistry. Enamel samples (4 mm x 5 …

Comparative Enamel Remineralization Using SDF, Fluoride Varnish, and Curodont™
… (SDF), and Curodont™ Repair on incipient enamel caries lesions in permanent teeth. Methods: Thirty-two enamel blocks were prepared from eight sound human permanent teeth. Artificial white spot lesions were induced using a Streptococcus mutans biofilm model over seven days with repetitive …

A Radiographic Analysis of Variance in Lower Incisor Enamel Thickness
The purpose of this study was to help predict the enamel thickness of mandibular incisors. At least two direct digital periapical radiographs were made for each of the 80 subjects. Radiographs were scaled to control for magnification errors using dental study models and computer software. …

Three dimensional surface texture analysis for characterisation of enamel erosion
… yet to be applied to dental erosion of human enamel. This project aimed to investigate the effect of acid-mediated erosive enamel wear on the micro-texture of polished (Group 1) and unpolished (Group 2) human enamel in vitro. 20 polished and 20 unpolished enamel samples were prepared and …

Fluoride uptake by enamel from stannous fluoride and prophylaxis pastes
… fluoride would promote a significantly greater enamel fluoride uptake than when the solution was applied alone; and (2) to determine whether rinsing the mouth with tap water immediately after these procedures would significantly affect enamel fluoride uptake. A modification of an in vivo, …

Characterising the deformation behaviour of human tooth enamel at the microscale
Enamel plays an important role in tooth function. Optimal combinations of composition and structure endow enamel with unique mechanical properties that remain largely unexplored. Specifically, more detailed understanding of the loadbearing ability of enamel is needed to mimic it synthetically and …

Two non-specific indicators of stress: Enamel hypoplasia and Harris lines
Harris lines (HL) and enamel hypoplasia (EH) are two non-specific indicators of stress, commonly used in the reconstruction of the health status in past and present populations. The aim of this study was to determine if there is a correlation between these two markers. To achieve this aim, a sample …
