endotracheal intubation is a medical procedure that places a breathing tube into the windpipe (trachea). It is used to help a person breathe or to control breathing with a ventilator during anesthesia or emergencies. In dentistry, it may be used for procedures done under general anesthesia, where the airway needs protection. It is most commonly performed by anesthesiology-trained clinicians in settings equipped for advanced airway care.

LMA is a term some dental teams use to describe a low-viscosity, resin-based material placed in thin layers during tooth repair. In plain terms, it is a “flowable” resin material that helps fill small areas and adapt closely to tooth surfaces. It is commonly used as a liner, small filling material, or repair resin under or alongside conventional composite restorations. Exact meaning and product selection can vary by clinician and case, and by material and manufacturer.

airway management is the set of clinical actions used to keep a person’s airway open and support breathing. It focuses on maintaining airflow to and from the lungs and ensuring adequate oxygen delivery. It is commonly used in emergency care, anesthesia, and dental sedation. In dentistry, it may be relevant during procedures where medications, positioning, or oral instruments could affect breathing.

general anesthesia is a medically controlled state of unconsciousness used for certain procedures. It typically includes loss of awareness, reduced pain perception, and limited movement during treatment. In dentistry, it is most often used for complex care, extensive treatment needs, or when cooperation is not possible. It is delivered and monitored by trained anesthesia professionals in appropriately equipped settings.

deep sedation is a level of medication-assisted sedation where a person is not easily aroused and may respond only to repeated or painful stimulation. It is used in dentistry to help patients tolerate procedures when anxiety, gag reflex, or procedure length makes routine care difficult. It is deeper than “minimal” or “moderate” sedation and requires closer monitoring of breathing and circulation. It is commonly provided in oral surgery and complex restorative care settings by trained clinicians in appropriately equipped facilities.

moderate sedation is a controlled level of sedation in which a patient is relaxed and sleepy but can still respond purposefully to verbal instructions (sometimes with light touch). It is commonly used in dentistry to help people tolerate procedures when anxiety, gag reflex, or treatment length would otherwise be a barrier. Patients typically continue to breathe on their own, and protective airway reflexes are generally maintained. It is different from deep sedation and general anesthesia, where responsiveness and airway support needs can be greater.

nitrous oxide sedation is a form of inhalation sedation that uses a mixture of nitrous oxide and oxygen. It is commonly used in dentistry to reduce anxiety and increase comfort during treatment. It is delivered through a small nose mask (nasal hood) while you remain awake and able to respond. Its effects typically start and wear off quickly once the gas is adjusted or stopped.

IV sedation is a form of sedation delivered through a vein using a small IV line. It is commonly used in dentistry to help patients feel calmer and more comfortable during treatment. It typically produces relaxation and reduced awareness, while local anesthesia still manages pain. It is most often used for longer procedures, complex care, or significant dental anxiety.

conscious sedation is a method of reducing anxiety and discomfort while keeping a person awake enough to respond to instructions. It is commonly used in dentistry and outpatient medical procedures to make treatment feel more tolerable. It is different from general anesthesia because protective reflexes and awareness are typically maintained to some degree. The exact technique and medication choice varies by clinician and case.

A nasopalatine block is a dental local anesthetic technique used to numb the front part of the roof of the mouth (the anterior hard palate). It targets the nasopalatine nerve as it passes through the incisive canal behind the upper front teeth. Dentists commonly use it to reduce sensation in palatal (roof-of-mouth) gum tissue during procedures in the upper front region. It is mainly a soft-tissue anesthesia method rather than a technique for numbing the teeth themselves.
