As a disclosure - the following is intended for informational purposes only. You should follow the advice of your dental expert (your dentist or endodontist) on this matter. An apicoectomy is an endodontic procedure in which the end of a root of the tooth in question and any inflamed or infected bone tissue around it are surgically removed (see aae.org/patients/patientinfo/faqs/endosu... for some graphics and a brief explanation).
According to 1800dentist.com/dental-encyclopedia/apic..." rel="nofollow">1800dentist.com/dental-encyclopedia/apic... the procedure takes between 30 and 90 minutes. As far as the type of anesthetics, according to 1800dentist.com/dental-encyclopedia/apic..." rel="nofollow">1800dentist.com/dental-encyclopedia/apic... this is a special anesthetic with double the amount of epinephrine compared to usual dentistry anesthetics which helps by constricting blood vessels in the area, reducing bleeding, and making it easier for the endodontist to see what s/he is doing. This is contra-indicated if e.g. You suffer from high blood pressure.
According to massoralsurgery.com/oral-surgery-norwood... : - quote - An apicoectomy can be accomplished comfortably in our office with any one of the following anesthetic techniques: local anesthesia, intravenous general anesthesia, intravenous conscious sedation, nitrous oxide anesthesia or oral sedation with local anesthesia. - end quote.
