To evaluate the efficacy of CO2 laser irradiation, with and without stannous fluoride gel, in sealing exposed dentinal tubules to treat cervical dentin hypersensitivity.
Extracted human teeth with naturally exposed cervical dentin received CO2 laser irradiation in the cervical region.
A subset of 10 teeth received a thin topical application of stannous fluoride gel prior to laser exposure.
Tubular closure, elemental deposition, and pulpal thermal changes were evaluated via scanning electron microscopy, electron probe microanalysis, and internal temperature probes.
Scanning electron microscopy demonstrated almost complete closure of dentinal tubules following laser irradiation.
Electron probe microanalysis confirmed the presence of tin within the sealed tubular openings of fluoride-pretreated teeth.
Laser irradiation produced a maximum internal temperature increase of 2.5°C within the pulp cavity.
