Characteristics of subgingival calculus detection by multiphoton fluorescence microscopy [PDF]
Journal of Biomedical Optics, 2011 Subgingival calculus has been recognized as a major cause of periodontitis, which is one of the main chronic infectious diseases of oral cavities and a principal cause of tooth loss in humans. Bacteria deposited in subgingival calculus or plaque cause gingival inflammation, function deterioration, and then periodontitis.

Real-time high dynamic range laser scanning microscopy
Nature Communications, 2016 Confocal and multiphoton fluorescence microscopy often suffers from low dynamic range. Here the authors develop a high dynamic range, laser scanning fluorescence technique by simultaneously recording different light intensity ranges.

Multiphoton microscopy imaging of developing tooth germs
Journal of the Formosan Medical Association, 2014 Traditionally, tooth germ is observed by histological investigation with hematoxylin and eosin stain and information may loss during the process. The purpose of this study is to use multiphoton laser fluorescence microscopy to observe the developing ...

Efficient multiphoton microscopy with picosecond laser pulses. [PDF]
Optics LettersMultiphoton microscopes employ femtosecond lasers as light sources because the high peak power of the ultrashort pulse allows for multiphoton excitation of fluorescence in the examined sample. However, such short pulses are susceptible to broadening in a

Value of multiphoton microscopy in uro-oncology: a narrative review
Translational Andrology and Urology, 2023 Background and Objective Multi-photon microscopy (MPM) is a 3-dimension fluorescence imaging technique that combines the excitation of two low-energy photons, enabling less photo-bleaching and deeper penetration of the imaged tissue.

Maximizing fluorescence collection efficiency in multiphoton microscopy
Optics Express, 2011 Understanding fluorescence propagation through a multiphoton microscope is of critical importance in designing high performance systems capable of deep tissue imaging. Optical models of a scattering tissue sample and the Olympus 20X 0.95NA microscope objective were used to simulate fluorescence propagation as a function of imaging depth for ...
