An improved Mineral Trioxide Aggregate (MTA) filling material for dentistry and a device for its use to seal natural, pathogenic, or iatrogenic, tooth cavities. The filling material comprises Portland cement, or variations in the composition of such cement, calcium sulfate and a radio pacifier material. The improved filling material exhibits favorable physical and chemical attributes sufficient to form a biocompatible and effective seal against re-entrance of infectious organisms. A device for delivery of MTA filling material to the site of operation is also provided.

A frame for a dental dam, a kit comprising the frame, and a method of accessing a patient's oral cavity during a dental procedure using the frame. A body of the frame defining two portions engaging with the dental dam at opposite sides of the body. The body is conformationally adaptable between an open configuration, where the two portions are splayed away from each other in the open configuration to spread out the dental dam, and a retracted configuration, where the two portions are drawn towards each other to fold the dental dam. The kit may have a device comprising a member suitable for biting on and elongated between an intraoral end and an extraoral end, an intraoral fitting at the intraoral end, and an aiming portion at the extraoral end that is positioned complementarily to the intraoral fitting about the member to facilitate extraoral targeting of the intraoral fitting.

A dental tool electrically powered by a power source includes: a handpiece having at least one switch; and a probe attachable to the handpiece so as to define a probe tip, the dental tool being operable to maintain the probe at its probe tip at a specifiable temperature. At least one of the handpiece and the probe includes a thermoelectric device, the dental tool being operable to maintain the probe at said probe tip at a specifiable temperature in response to user actuation of the at least one switch. Optionally, a second handpiece having an electrically conductive enclosure houses a second switch held by the patient. A method of conducting a dental test on a tooth of the patient includes: generating a sensory stimulus at the probe tip when the probe tip is in contact with the tooth; and receiving an actuation by the patient of the second switch.
