[Outcome of 500 cases of transcortical anesthesia carried out as the first choice].

Transcortical anesthesia, like all anesthetic techniques, is founded on anatomical, physiological and histological principles. Its fundamental principle and clinical data that support it indicate that it could advantageously replace most other techniques. Indeed, a study carried out by 3 dental surgeons involving 500 transcortical procedures as the first choice for anesthesia confirms this possibility and emphasizes the principal advantages: Immediate anesthesia of several (2 to 6) maxillary or mandibular teeth with a single vestibular injection (without additional palatine or lingual injection); elimination of cheek and lip numbness; use of concentrated vasoconstrictor with no risk of necrosis to solve the problem of immediate anesthesia of teeth with pulpitis.
