General Anesthesia Unit

Sedation or general anesthesia may be used when local anesthesia alone does not provide sufficient pain control, when a patient has very high levels of fear or anxiety, or when adequate cooperation cannot be achieved. This may include young children, individuals with intellectual disabilities, or patients with movement disorders.

General anesthesia is a procedure performed by anesthesiologists who are specially trained in this field. It involves placing the patient in a controlled state of unconsciousness in which they do not experience pain. These procedures should be carried out in facilities that meet operating-room standards and are equipped with all necessary medical devices, monitoring systems, medications, and emergency equipment.

Particularly during lengthy surgical procedures or in patients with severe fear and anxiety, sedation and general anesthesia can significantly improve patient comfort. A large proportion of patients who may require dental treatment under general anesthesia are young children.

The term sedation was traditionally defined as a state in which anxiety and fear are eliminated, reduced, or prevented, while the patient remains conscious but under the influence of medication. Although this definition is generally correct, sedation is more accurately classified according to the patient’s level of consciousness and physiological response. In dental patients, conscious sedation, deep sedation, and general anesthesia may be defined as follows:

Moderate Sedation (Conscious Sedation)

Moderate sedation is a medication-induced reduction in the patient’s level of consciousness in which the patient is still able to maintain their airway independently and continuously. The patient can respond appropriately to verbal commands and physical stimulation.

Deep Sedation

Deep sedation is a medication-induced state in which the level of consciousness is significantly reduced and controlled. Protective airway reflexes may be partially or completely lost, and the patient may respond inadequately to verbal commands.

The patient cannot be easily awakened but may respond meaningfully to repeated verbal or painful stimulation. Because respiratory function may become impaired, breathing support may sometimes be required.

General Anesthesia

General anesthesia is a reversible, medication-induced state of unconsciousness in which the patient does not respond even to painful stimulation.

Spontaneous respiratory function usually cannot be maintained without assistance. Airway management and positive-pressure ventilation are therefore generally required.

Sedation and General Anesthesia in Pediatric Dentistry

Providing dental treatment for children who have severe fear or anxiety, or for children with disabilities who are unable to cooperate adequately, can be a significant challenge in pediatric dentistry.

The prevalence of dental caries among children may be high, and treatment can become particularly difficult in children who are unable to cooperate. When primary teeth cannot be treated and must be extracted prematurely, the likelihood of future orthodontic problems may increase. Orthodontic treatment can be lengthy, demanding, and costly.

Different approaches may be used for young children who have difficulty cooperating with the dentist. These approaches can generally be divided into psychological and pharmacological methods.

Psychological methods, particularly behavior guidance techniques, are widely used by pediatric dentists. The success of these methods depends largely on the dentist’s ability to communicate effectively with the child, establish trust, and help the child become comfortable with dental treatment.

When psychological approaches are insufficient, pharmacological methods may be considered. These involve the use of medications to provide sedation or, when clinically necessary, general anesthesia.

In many countries, sedation techniques are routinely used for pediatric patients who are unable to cooperate, both in dental clinics and hospital settings. In Türkiye, young children or children with severe dental anxiety may present with extensive dental caries requiring multiple or lengthy procedures. In such cases, particularly when cooperation cannot be achieved, dental treatment may be performed under general anesthesia when clinically appropriate.
