2026 COMPLETE QUESTIONS AND VERIFIED

◉ Nerve block. Answer: Type of injection that anesthetizes a larger

near large nerve trunks(wide area)
◉ Paresthesia. Answer: Abnormal sensation from an area such as
burning or prickling
◉ Papal anesthesia. Answer: getting tooth numb for drilling
◉ Soft tissue anesthesia. Answer: scaling and root planning
◉ Bones involved in LA are?. Answer: maxilla, palatine bone, and

◉ Trigeminal supplies sensory information for?. Answer: teeth and
associated structures
, ◉ The clinician must never progress the needle through an area

surface of the maxillary teeth is less dense than that of the mandible
over similar teeth
*Less variation of anatomy of the maxillary and palatine bones with
respect to landmarks than the mandible
◉ Anterior superior alveolar (ASA). Answer: Maxillary canine and
incisors and associated facial tissues
◉ ASA penetration site. Answer: Tissues at the height of the
mucobuccal fold at the apex of the maxillary canine, just anterior to
and parallel with the canine eminence
◉ ASA complications. Answer: Over-insertion with complications
