Erosive tissue-loss in dental enamel is of significant clinical concern because the net loss of enamel is irreversible, however, initial erosion is reversible. Micro-hardness testing is a standard method for measuring initial erosion, but its invasive nature has led to the investigation of alternative measurement techniques. Optical coherence tomography (OCT) is an attractive alternative becaus...

Crush preparation cytology technique was used during the operative procedure for the diagnosis of 199 CNS tumors. This technique is simple, easy to perform, rapid, and inexpensive. The cytomorphologic findings were excellent and helped achieve a rapid and correct diagnosis. This technique was used on the tiny, small specimens which were not suitable for frozen sectioning. The results were c...

Purpose: To provide an overview of different indications suitable for treatment with the technique of resin infiltration (Icon, DMG), such as white-spot lesions (WSL), enamel fluorosis, and molar-incisor hypomineralisation (MIH), and to propose a valid and strategy feasible in dental surgeries for screening of dental color improvement and -stability. Method: A non-systematic review of the liter...

Laser ablation of dental hard tissues is one of the most important laser applications in dentistry. Many works have reported the interaction of laser radiations with tooth material to optimize laser parameters such as wavelength, energy density, etc. This work has focused on determining the relationship between energy density and ablation thresholds using pulsed, 5 nanosecond, neodymium-doped y...

AIM Cheeses have been investigated for their potential cariogenicity in several studies and have been shown to produce little change in the resting pH in dental plaque and little or no demineralisation of enamel in most intra-oral cariogenicity studies. The aim of the present study was to investigate the cariogenicity of four processed cheese formulations. METHODS Enamel demineralisation was ...

The effect of sealant placement and sealant loss on caries-like lesion formation was studied using an artificial caries technique and polarized light microscopy. The results indicate that lesion formation does not occur subjacent to an intact sealant. Even enamel which had lost is sealant was found to be caries-free. It is concluded that resin tags may be responsible for the ability of sealants...

INTRODUCTION In this in-vitro study, we aimed to investigate the predictability of the expected amount of stripping using 3 common stripping devices on premolars. METHODS One hundred eighty extracted premolars were mounted and aligned in silicone. Tooth mobility was tested with Periotest (Medizintechnik Gulden, Modautal, Germany) (8.3 ± 2.8 units). The selected methods for interproximal ename...

In transverse sections the areas of enamel, dentine and pulp were determined using image analysis morphometry, and the mineralization levels of enamel, dentine and alveolar bone using quantitative microradiography and a microphotometric-microdensitometric technique. There were significant differences in the ratios of dentine to pulp area, and in the enamel to total area in the incisors from dwa...
