    摘要： An improved method of endodontic therapy utilizes two strategies to create long lasting and effective dental restoration. After a root canal is prepared by conventional means, a dye is flooded into the canal to stain residual infected tissue. The dye is selected to enhance the absorption of radiant energy by dyed tissue by matching at least one λmax of the dye to the output of a laser. The radiant energy (24) from the laser is then used to obliterate all infected root tissues (16) remaining within the prepared root canal (14). Laser treatment extends from the root apex (12) to the tooth corona (18). Second, cements utilizing an anti-microbial agent such as zinc pyrithione are used to restore the tooth, giving the restoration inherent anti-microbial properties. While ideally used together, each strategy may also be utilized on its own for improvement over the prior art.

    摘要： A dental pulp capping composition can comprise a particulate base material which is non-toxic, and capable of forming a structural capping matrix; and a particulate setting material which is non-toxic, water-soluble, biocompatible, and capable of setting the composition. Optional growth factors can also be introduced into the composition to facilitate dental tissue repair. A complimentary method of restoring damaged tooth features can comprise removing diseased and/or damaged portions of the tooth to expose a prepared tooth region. Water can be added to the dental pulp capping composition to form a workable coherent paste. The workable coherent paste can be introduced into the prepared tooth region. The workable coherent paste can then be shaped within the prepared tooth region and then set to form a rigid biomimetic structure within the prepared tooth region.
