AIM The morphology of permanent and primary enamel surface merits further analysis. The objective of this study was to illustrate a method of SEM digital image processing able to quantify and discriminate between the morphological characteristics of primary and permanent tooth enamel. METHODS Sixteen extracted teeth, 8 primary teeth and 8 permanent teeth, kept in saline solution, were analyse...

Fluorescence spectra of dentine and enamel illuminated with laser light of wavelengths of 337, 488, 515 and 633 nm respectively were recorded. The fluorescence obtained by illumination with UV laser light at 337 nm had a peak at about 400 nm in dentine as well as enamel. Compared to intact enamel the fluorescence from enamel with initial carious lesions was of lower intensity and had a slight r...

INTRODUCTION The aim of this study was to check opportunities of early caries detection in primary dentition by using new portable device--KaVo Diagnodent. Values of Diagnodent were interpreted by Hibst and Paulus scale. It was also decided to check if this scale is useful for detecting caries in milk teeth. In this study a new author's scale was used. Values of Diagnodent were also interpreted...

BACKGROUND Coronal resorption is a coronal degeneration of enamel and dentine in which ultimately the crown is replaced by vascular connective tissue through a defect in the enamel organ of an unerupted tooth. This is also known as pre-eruptive coronal resorption. However, the aetiology of resorption remains unclear. CASE REPORT A 13 years 7 months old Caucasian boy who attended an orthodonti...

GOALS AND BACKGROUND European studies have demonstrated that dental enamel defects and oral aphthae are observed in celiac disease (CD). We investigated this association in a US population. STUDY Biopsy proven CD patients and controls were recruited from a private dental practice and from CD support meetings. History of aphthae was taken and dental examination was performed by a single dentis...

This crossover study with 46 child dental patients compared two topical APF products, a gel and a foam, with respect to the amounts of product and fluoride (F) applied, salivary F concentrations, and enamel F uptake. Half the subjects were treated for 4 min with the gel first and the other half with the foam. After approximately 16 days, each patient received a second treatment using the other ...
