A reciprocating endodontic hand tool in which the torque applied to an instrument such as a debriding file can be set at or below an endurance limit of the file below which failure of the instrument will not occur. In preferred embodiments the tool can switch between settings in which the torque applied to the instrument is between the endurance limit of the file and an elastic limit of the file, by setting forward and reverse angles of rotation within specified limits. This reduces or eliminates opportunities for plastic distortion, fatigue and breakage of the file during the canal debriding/cleaning/shaping process in a root canal treatment or retreatment. In some embodiments the torque may be set to at or below a durability limit of the file below which failure of the instrument will not occur through repetitive strain over the course of a particular root canal treatment or retreatment.

Embodiments of the invention provide a system of controlling a dental laser system. The system can include a dental laser and a control system for controlling certain functions of the dental laser. A graphical user interface can be used to provide input to the control system. The graphical user interface can include a first display and an second display with selectable segments, and a menu navigation portion located adjacent the second display. Treatment categories, procedures or laser control options can be selected using the interface, and the interface can be updated based on data from the station.

The present invention relates to a device and a method for measuring osseous quality.

The invention relates to structures of a dental care unit used in dental care work. In the invention, a frame part of the dental care unit comprises a means to attach a vertically extending support part, and a cover structure (22) of the frame part comprises at least a first and a second cover part (22′, 22″). The support part extends vertically essentially from an area of a seam locus (23) between the cover parts, whereto is arranged a seam element (24). The seam element (24) is preferably arranged to emit light as controlled by a control system of the dental care unit. A dental care unit like this is specifically applicable for use in a dental care room or premises comprising several dental care units.

A method for automatically initiating a dental handpiece waterline flushing mode in a dental delivery system comprises detecting whether at least first and second handpiece waterlines from a plurality of handpiece waterlines are removed from respective first and second rest positions of a control head for the dental delivery system. According to some implementations, if it is determined that no additional dental handpiece waterline which is flushable remains in a rest position of the control head, then the dental handpiece waterline flushing mode is automatically initiated for the first and second dental handpiece waterlines. In some implementations, a display is updated to provide information to a user, and an input from the user is received to begin flushing.

A method for excavating tooth material, having the steps of placing (S101) a structure-borne sound sensor on a tooth; excavating (S102) the tooth material by means of a fluid jet; detecting (S103) structure-borne sound signals during excavation by the structure-borne sound sensor; and regulating or controlling (S104) a fluid jet generating device based on the structure-borne sound signals.

The present disclosure is directed to systems and methods for electronic control of an operating level of an oral irrigator, particularly when flow from the oral irrigator is paused. Methods for controlling an operational level include: determining an operational level of the oral irrigator, including whether the operational level is a standby mode; receiving sensor data from one or more sensors; determining whether a key sensor indicator is above, below, or at a threshold. If the key sensor indicator is above a threshold, the operational level is changed to standby mode. If the key sensor indicator is at or below the threshold, the operational level remains at the current level. If the key sensor indicator is below the threshold, and the current operational level is the standby mode, the operational level is changed to the operational level set before entering standby mode.

The invention relates to a projector construction (86) arranged both structurally and operatively integrated into a dental operating light (8) so as to be a part of the dental operating light (8) and wherein the dental operating light (8) illuminates a first area on a surface whereas the projector construction (86) is configured to project graphics, pictures and/or video in essentially the same direction as the operating light (8) on the surface, on a second area.

An apparatus assisting in dental procedure, comprising: a body adapted to be received with an oral cavity; an anchoring means for securing the body within the oral cavity such that it at least partially surrounds one or more teeth; a dental device located within the body and adapted to move in a plurality of planes relative to the one or more teeth; and a controller for controlling the dental device to move into a suitable position relative to the one or more teeth and once located in position carry out work on or about the one or more teeth.
