A measurement system is provided with an array of laser diodes with one or more Bragg reflectors. At least a portion of the light generated by the array is configured to penetrate tissue comprising skin. A detection system configured to: measure a phase shift, and a time-of-flight, of at least a portion of the light from the array of laser diodes reflected from the tissue relative to the portion of the light generated by the array; generate one or more images of the tissue; detect oxy- or deoxy-hemoglobin in the tissue; non-invasively measure blood in blood vessels within or below a dermis layer within the skin; measure one or more physiological parameters based at least in part on the non-invasively measured blood; and measure a variation in the blood or physiological parameter over a period of time.

A bacteria removal laser is provided, especially for removing caries bacteria from natural or prosthetic teeth, the prosthetic teeth also being treated via extraoral approach, having a gripping handle, a laser radiation source, an application optics having a predetermined radiation exit surface, especially a radiation guide rod through which laser radiation passes, and an energy source such as a mains connection or an accumulator. The laser emits in the wavelength range between 2200 nm and 4000 nm and is especially designed as an Er:YAG laser. The energy output averaged over time is less than 1 mJ/mm.sup.2 at the radiation exit surface.

A laser and a minimally invasive dental surgical procedure using the laser to stimulate periodontal tissue formation.

A method of treating gum disease while healing the wound in the periodontium using a soft tissue diode laser which generates a beam of light having a wavelength in the visible portion of the electromagnetic spectrum (400 nm-700 nm) at a laser power of 0.001 to 1.2 watts, used with intermittent stops to control tissue temperature and biostimulate the periodontium to regenerate and heal its wound when used with substrates, the method comprising: placing the tip of the laser inside the sulcus; penetrating the entire sulcus by moving the laser light circumferentially around the tooth vertically and horizontally throughout the sulcus with intermittent stops to control tissue temperature and placing substrates in the sulcus prior to blood clot formation; followed by RF treatment of the sulcus by placing the RF headpiece tips perpendicular to the sulcus to receive RF current which further penetrates the wound site.

Embodiments of the invention provide a laser system including a laser station including at least one laser, at least one processor, and at least one non-transitory computer-readable storage medium in data communication with the at least one processor. The at least one non-transitory computer-readable storage medium includes program instructions executable by the at least one processor, and enabling or operating an exchange of data between the at least one laser station and at least one remote network. The laser system includes at least one GUI display configured and arranged to display operating parameters or functions of the at least one laser and/or any of the data exchanged between the laser station and at least one remote network. The program instructions include instructions that direct the processor to update the at least one GUI display with a plurality of user-selectable graphics arranged around the periphery or circumference of a central display.

The invention relates to a system consisting of a laser which emits laser radiation with a wavelength of more than 1300 nm, in particular between 2750 nm and 3200 nm, and a dental adhesive for applying a dental restoration part to a pre-treated, in particular cleaned, adhesive base which is formed by hard dental tissue or by denture material. The viscous dental adhesive applied to the adhesive base, which is free of a dental restoration part, can be activated, in particular without blowing or agitation, by applying laser radiation.

The invention relates to a method for sealing of a circumferentially closed canal. A closure element is secured to one free end of a light guide conducting a laser beam. The light guide with the closure element is introduced into the canal. The closure element is positioned in the region of the canal to be sealed and after positioning of the closure element energy is introduced, so that the closure element melts or softens and remains in this position in the canal and seals it tightly.

A dental instrument for use with a dental handpiece cleans and disinfects tooth root canals. The instrument includes a shaft and connector for releasable attachment to the handpiece, the shaft including at least a tip end, a distal portion approximate to the connector, and at least two radial protrusions extending along length of the shaft with a longitudinal groove extending between the at least two radial protrusions.

Embodiments relate to a systems and methods for preventative irradiative dental treatment. In accordance with one embodiment, a system and method include using a radiation source to generate a radiation; using an optic disposed to accept the radiation to internally reflect he radiation at a first end; using at least one side of the optic to contact a dental hard tissue; using the optic to couple some of the radiation into the dental hard tissue; and, using a controller to control a parameter of the radiation to heat a surface of the dental hard tissue.

Methods and systems for modifying tissue use a pressurized fluid stream carrying coherent light energy. The methods and systems may be used for resecting and debulking soft and hard biological tissues. The coherent light is focused within a stream of fluid to deliver energy to the tissue to be treated.
