Bio-Photonic Detection and Quantitative Evaluation Method for the Progression of Dental Caries Using Optical Frequency-Domain Imaging Method

Sensors, 2016
The initial detection of dental caries is an essential biomedical requirement to barricade the progression of caries and tooth demineralization. The objective of this study is to introduce an optical frequency-domain imaging technique based quantitative ...

A Possible Case of Temporomandibular Joint Dislocation, Trepanation, and Metabolic Bone Disease in a Young Adolescent From North‐Central Myanmar (1000–700 bce)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This osteobiography explores the life history of an adolescent who lived during the early‐mid Bronze Age (c. 1000–700 bce) and was buried at Nyaung'gan, a site in north‐central Myanmar. Burial 3b had multiple skeletal lesions, and their bones were covered in well‐remodeled subperiosteal new bone.

Autogenous fresh demineralized tooth graft prepared at chairside for dental implant [PDF]

Maxillofacial Plastic and Reconstructive Surgery, 2015
This study aimed to evaluate the clinical usefulness of autogenous fresh demineralized tooth (auto-FDT) graft prepared at the chairside for alveolar bone grafting during dental implant surgery.In total, 38 patients requiring both tooth extraction (for endodontic or periodontal reasons or third molar extraction) and alveolar bone regeneration for dental

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

Quantitative collagen and proteoglycan imaging reveal organic layering, gradients and regional texture in young mature dental cementum

VIEW, EarlyView.
Cementum, the mineralized tissue covering all mammalian tooth roots, helps maintain tooth stability, but its internal organization is still poorly understood. In this study, we combine quantitative histologial methods to map the regional distributions of collagen fibers and proteoglycan‐rich matrix layers in porcine cementum.

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.

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...
