Title: Method of polymerizing photo-polymerizable composition for dental use and dental light-curing apparatus for use therewith

Abstract: A method of polymerizing a photo-polymerizable dental composition with the use of a light-curing apparatus including a light source (1) for emitting a laser beam and an optical fiber (2) optically coupled with the light source (1) and having a light emitting element (5) opposite to the light source (1). The photo-polymerizable dental composition (M) is filled in a dental cavity (H), and the light emitting element (5) of the optical fiber (2) is subsequently introduced in the filled photo-polymerizable dental composition (M) to a position adjacent a bottom of the dental cavity (H). Thereafter, the filled photo-polymerizable dental composition (M) is irradiated with the laser beam of 350 to 500 mm in wavelength at 10 to 100 mW, to cause the filled photo-polymerizable dental composite (M) to initiate polymerization progressively from a portion thereof adjacent the bottom of the dental cavity (H) towards a surface portion thereof.
