Effect of different atmospheres on microcosm biofilm formation and tooth demineralization

, 2022
AbstractThis study evaluated the effects of different atmospheres on the cariogenic potential of microcosm biofilms. Ninety bovine enamel and 90 dentin specimens were allocated into three atmospheres: 1) microaerophilia (5 days, 5% CO2); 2) anaerobiosis (5 days, jar); 3) mixed (2 days microaerophilia and 3 days anaerobiosis), which were subdivided into

Methods for calculating the severity of demineralization on tooth surfaces from PS-OCT scans [PDF]

SPIE Proceedings, 2009
Several studies have demonstrated that polarization sensitive optical coherence tomography (PS-OCT) can be used to nondestructively measure the severity of subsurface demineralization in enamel and dentin. The reflectivity in the polarization state orthogonal to the initial linear polarization incident on the tissue is low at sound tissues interfaces ...

In situ evaluation of the bleaching efficacy of experimental hydrogen peroxide hydrogel with MnO‐doped Biosilicate activated by violet LED light

European Journal of Oral Sciences, EarlyView.
Abstract Hydrogen peroxide (HP) at 35% is effective for dental bleaching but may reduce enamel mineral content and induce structural changes. This study developed a bleaching‐hydrogel containing 6%HP and manganese‐oxide–doped Biosilicate (MnO_BioS), activated by violet LED, under in situ conditions.

Imaging of demineralized enamel in intact tooth by epidetected stimulated Raman scattering microscopy [PDF]

Journal of Biomedical Optics, 2018
Stimulated Raman scattering microscopy (SRS) was deployed to quantify enamel demineralization in intact teeth. The surfaces of 15 bovine-enamel blocks were divided into four equal-areas, and chemically demineralized for 0, 8, 16, or 24 h, respectively. SRS images (spectral coverage from ∼850 to 1150  cm  -  1) were obtained at 10-μm increments up to 90

Role of adjunctive methacryloyloxydecyl dihydrogen phosphate primers on dentin bond strength of universal adhesives under saliva and artificial aging

European Journal of Oral Sciences, EarlyView.
Abstract This study evaluated whether adjunctive 10‐methacryloyloxydecyl dihydrogen phosphate (MDP) primers enhance the microtensile bond strength (µTBS) of two universal adhesives (UAs) to dentin under artificial aging and repeated salivary contamination applied at each bonding step.

Near‐IR image‐guided laser ablation of demineralization on tooth occlusal surfaces [PDF]

Lasers in Surgery and Medicine, 2016
IntroductionStudies have shown that reflectance images at near‐IR wavelengths coincident with higher water absorption are well‐suited for image‐guided laser ablation of carious lesions since the contrast between sound and demineralized enamel is extremely high and interference from stains is minimized.

Influence of rubbing during etching on surface roughness and interfacial characteristics of intact enamel

European Journal of Oral Sciences, EarlyView.
Abstract Rubbing phosphoric acid during etching has been shown to improve surface roughness in prepared enamel. This study aimed to compare intact enamel's surface roughness and resin tag lengths after etching with and without rubbing. Extracted sound third molars were used for testing, mesially for conventional and distally for dynamic (rubbing ...
