Abstract
A method of polymerizing a photo-polymerizable dental composition with the use of a light-curing apparatus including a light source (,) for emitting a laser beam and an optical fiber (,) optically coupled with the light source (,) and having a light emitting element (,) opposite to the light source (,). The photo-polymerizable dental composition (M) is filled in a dental cavity (H), and the light emitting element (,) of the optical fiber (,) 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.
