For the endodontic practitioner, the dental microscope is useful for diagnosis and clinical procedures.
The microscope may aid diagnostically in identifying caries, insufficient crown or restorative filling margins, or assessing craze or fracture lines.
During root canal therapy, magnification and illumination provided by the operating microscope aids with caries removal, access preparation, removal of pulp chamber calcifications, identification of root canal orifices, identification of cracks and fracture lines, and the treatment of internal resorptions.
Under the microscope, subtle changes in dentin color and texture become apparent, such as developmental lines on the pulp floor guiding the practitioner towards root canal orifices, or the darker color of the pulp floor itself, allowing the practitioner safer dentin removal.
