We aimed to create a slippery liquid-infused enamel surface with antibiofouling property to prevent dental biofilm/plaque formation. First, a micro/nanoporous enamel surface was obtained by 37% phosphoric acid etching. The surface was then functionalized by hydrophobic low-surface energy heptadecafluoro-1,1,2,2-tetra- hydrodecyltrichlorosilane. Subsequent infusion of fluorocarbon lubricants (Fl...

objectives: this study aimed to compare the incidence of white spot lesions (wsls) around orthodontic bands following the application of two glass ionomer (gi) cements namely gc gold label and gc fuji plus for six to 12 months. materials and methods: a total of 186 permanent first molars of orthodontic patients requiring banding of at least two permanent first molars were chosen. the teeth were...

Background: To increase the effectiveness of orthodontic treatment in children with various degrees of dental enamel caries resistance using a personified orthodontic treatment. Materials and Methods: The present study included 108 adults (6-16 years old) with the first class of occlusion who referred for the Department of Pediatric Dent...

Fluoride is now accessible in a variety of forms, including water, toothpaste, mouth rinses, and professional fluoride therapy at dental clinics. A body of data supports the use of systemic and topical fluoride from various sources to prevent dental caries. Fluoride ions are absorbed by the enamel prior to tooth eruption and produce fluorohydroxyapatite, which is more resistant to acid attack t...

AIM To compare the prevalence of dental caries, dental calculus, and enamel defects in children with cystic fibrosis (CF) and children with other chronic respiratory disorders. METHODS A cross sectional observational survey. One examiner (AN) undertook oral examinations to assess dental caries, periodontal health, and enamel defects in children attending respiratory outpatient clinics. RESU...

Dental enamel is the structure which is first exposed to the attack of dental caries, and the success or failure of this attack depends on many factors, among them the chemical nature and structure of the enamel. Some authors (Pincus, 1939; Gottlieb, 1947) go so far as to postulate that the caries process is initially a proteolytic one. In this connexion the nitrogenous material of enamel is of...

While many effectors have been identified in enamel matrix and cells via genetic studies, physiological networks underlying their expression levels and thus the natural spectrum of enamel thickness and degree of mineralization are now just emerging. Several transcription factors are candidates for enamel gene expression regulation and thus the control of enamel quality. Some of these factors, s...

FTR-Raman Spectra of human dental enamel, both laser-irradiated and untreated, are reported. Spectra are compared with hydroxyapatite. It is evident that unlike the CO2 laser, the Nd/YAG laser does not induce any chemical change in dental enamel.

All vertebrate organs are formed from several cell types, and it is currently believed that interactions between the different components constitute the most important mechanism in the regulation of organ morphogenesis. In developing teeth morphogenetic interactions occur between the epithelium covering the facial processes and the underlying neural crest-derived mesenchyme. Morphogenesis is ac...

Dentin matrix protein 1 (DMP1) is an acidic phosphoprotein that plays an important role in mineralized tissue formation by initiation of nucleation and modulation of mineral phase morphology. The purpose of the present study was to examine the immunoexpression of DMP1 in tooth germs of 7 human fetuses at different gestational ages (14, 16, 19, 20, 21, 23 and 24 weeks) comparing with completed t...
