The invention provides isolated nucleic acids molecules, designated TLCC-3 nucleic acid molecules, which encode novel TRP-like calcium channel molecules. A device for expanding an arch of teeth of a patient can include a removable shell formed of a first material having a number of cavities formed therein. A lubricant for die lubrication prepared by mixing at least two different lubricants having melting points higher than a predetermined temperature of the compaction pressure is sprayed at the upper part of the die and is introduced into the die and adhered by electrification to the surface of the die. A rechargeable battery pack provides electric power and the light source may be a fluorescent light bulb.
