Sedation allows patients to maintain their airway independently and respond appropriately to physical stimulation and verbal command while maintaining a minimum depressed level of consciousness. Drugs commonly used for sedation of pediatric dental patients include a combination of chloral hydrate, hydroxyzine, and nitrous oxide-oxygen. Midazolam is a benzodiazepine and currently one of the most commonly used intravenous sedative agents. It can be easily titrated to provide a wide range of sedation, from conscious sedation to deep sedation, and exhibits a wide safety margin without severe respiratory and circulatory depression. At an appropriate dose, it also decreases patient anxiety and induces amnesia. We found that the submucosal administration of midazolam combined with chloral hydrate provided increased sedative effects and decreased the postoperative vomiting response compared with conventional chloral hydrate administration, with no significant difference in physiological responses. The depth of sedation can be titrated using this technique.

Sedation is frequently required to relieve anxiety in the field of dentistry. Among sedation techniques, oral sedation has been widely used because it is easy for administration and has a wide acceptability for dentists. This article discuss the pharmacology of oral sedatives and therapeutic considerations of these drugs, and finally how to manage apprehensive patients using oral sedation. Also, we recommend how pertinent drugs should be used to maintain an adequate level of sedation, not deep sedation

Although sevoflurane sedation have the advantage of the reduction of anxiety and pain relief, difficult airway is attributed to increased agitation, tachycardia, desaturation, ventilation difficulty, sedation failure. In the sedation for dental treatment, we should pay more attention to the airway management because dental procedures take place in the mouth of airway unlike any other area. The layngeal mask airway (LMA) has become commonly used device for airway management during anesthesia for relatively short procedures, such as minor oral surgery and dental procedures. It can be inserted without use of a larygoscope and muscle relexants, and insertion is easy to achieve and generally takes less time than endotracheal intubation. The LMA is an excellent barrier against aspiration of saliva, blood within the surgical field but should not be used in patients at risk of aspiration In this study, we reported that after a failure of airway management in inhalation sedation, we performed the short-emergency dental treatment successfully, using a laryngeal mask.

Background: The objective of the present study was to examine the status of patients who had received dental treatment under intravenous (IV) sedation at Chungnam Dental Clinic for the Disabled in Korea from its inception to the present time, and to review the analysis results. Methods: Retrospective analysis was performed on 305 cases of patients who had received dental treatments under IV sedation between January 2011 and May 2016. The analysis examined the patient's sex, age, primary reason for IV sedation, duration of anesthesia and dental treatment, type of dental treatment performed, number of clinical departments involved in the dental treatment and level of multidisciplinary cooperation, and annual trends. Results: Most dental treatments using intravenous sedation were performed on medically disabled patients or dentally disabled patients with an extreme gag reflex or dental phobia. The mean duration of IV sedation was 72.5 min, while the mean duration of treatment was 58.0 min. The types of dental treatments included surgical treatment (n = 209), periodontal treatment (n = 28), prosthodontic treatment (n = 28), restorative treatment (n = 23), implant surgery (n = 22), endodontic treatment (n = 9), reduction of temporomandibular joint dislocation (n = 1), and treatment of traumatic injuries (n = 1), with treatments mostly performed on adult patients. Conclusions: With increasing demand for minimally painful treatment, cases using IV sedation are on an upward trend and are expected to continue to increase.

This article discusses the provision of sedation for uncooperative special need dental patients. Most of dental treatments have been performed in these patients with the techniques of behavioral control. However, if this behavioral control fails during treatment, it is nearly impossible to treat them without either sedation or general anesthesia. Sedation is also beneficial for patients because it circumvent the aggravation of negative behaviors related to their stress during the treatment. Also, the morbidity and mortality related to dental sedation is relatively low. In this regard, the provision of sedation for people with special needs can be considered as a safe and necessary techniques for their treatment.

Patients with severe gag reflex (SGR) have difficulty getting the treatment they require in local clinics, and many tend to postpone the start of their treatment. To address this problem, dentists have used behavioral techniques and/or pharmacological techniques for treatment. Among the pharmacological methods available, propofol IV sedation is preferred over general anesthesia because it is a simpler procedure. Propofol in combination with remifentanil is characterized by stable sedative effects and quick recovery, leading to a deep sedation. Remifentanil acts to reduce the pain caused by lipid-soluble propofol on injection. The synergistic effects of propofol-remifentanil include reduction in the total amount of drug required to achieve a desired sedation level and anti-emetic effects. In this case report, we outline how the use of propofol-remifentanil IV sedation enabled us to successfully complete a wide range of dental treatments in a patient with SGR.

Background: The purpose of this study was to evaluate the safety and effectiveness of intravenous ketamine-midazolam sedation in uncooperative children and disabled people undergoing dental procedures. Methods: From September 2009 to January 2012, total 114 intravenous deep sedation were carried out using midazolam and ketamine at pediatric dentistry in Wonkwang University Daejeon Dental Hospital. Patients' dental charts and sedation records were retrospectively reviewed. Results: 103 cases were enrolled, divided into four groups. There were 22 children under five in group 1, 14 children over six years with severe anxiety in group 2, 34 disabled person in group 3 and 33 children over six years with surgical procedure in group 4. Carries treatment (56 cases) was the most common dental treatment. The highest ketamine usage was 4.15 mg/kg, the longest duration of dental treatment was 41.6 minutes in children under five group. Nausea and vomiting (16 cases) was the most common side effect. Conclusions: Intravenous ketamine-midazolam sedation appears safe and effective for uncooperative children and disabled person undergoing dental procedures. But, emesis is a common side effect of ketamine occurring with increasing age.

Apprehension and phobia regarding dental procedures are represent the most common deterrents in patients seeking dental care and very common. For these individuals, and others who cannot cooperate during care, procedural sedation may permit completion of intraoral procedures. In most cases, the level of sedation may be kept at minimal to moderate levels permitting patient maintenance of their airway patency and ventilation. Unlike many medical procedures, the majority of dental procedures, no matter the depth of sedation, are performed in the presence of complete analgesia provided by local anesthesia. Therefore, the goal of procedural sedation is to primarily suppress patient fear and apprehension and gain cooperation. Any issues regarding actual pain are usually limited to that produced by the local anesthetic injections or, rarely, the extent of the procedure. For the extremely phobic patient, however, allaying apprehension may be very challenging. Intravenous titration of sedative drugs is the most effective route of administration to achieve this goal but requires advanced training beyond that provided in undergraduate training.

Background: Emergency room doctors run into difficulties in treating injured pediatric patients because usually they fell into panic after trauma. In these situation, deep sedation with sevoflurane is fully recommendable method. The conventional way can interrupt common dental treatment procedure. Methods: In the present study, nasal cannula was used for sevoflurane deep sedation in 11 dental emergency treatment. Age ranged from 0 to 3 years old (average of 1.8 years). Results: Treatment duration was from 10 to 35 minutes (average of 16.7 minutes). Average duration of sedation was 25.5 minutes ranging from 15 to 45 minutes. Conclusions: It has advantages to use nasal cannula for sevoflurane deep sedation rather than conventional intubation; saves time and secures good operation field.

The gag reflex is a physiological reaction, but, an exaggerated gag reflex can be a severe limitation not only to treat dental caries but also to do oral exam. Procedures such as surface anesthesia of the palate and pharyngeral area, sedation, or general anesthesia can be options as behavioral management. But, there are no golden rule for the sever gag reflex patients. We present a case report of propofol intravenous sedation using TCI pump for simple dental treatment. A 44-year-old man, who had past history of general anesthesia for dental treatment because of severe gag reflex, was scheduled intravenous sedation for simple dental treatment. After 8 hour fasting he entered the clinic for persons with disabilities. We explained about intravenous deep sedation and got informed consent. First, we kept intravenous catheter (22G) in the arm and started monitoring ECG, non-invasive blood pressure, pulse oximetry and end-tidal $CO_2$ through nasal cannula. We started propofol infusion with TCI pump at the target concentration of 3 mcg/ml. The patient became sedated, but he showed involuntary movement during dental treatment, so we increased the target concentration to 4 mcg/ml. We finished the dental treatment without complications during 30 min. And after 40 min recovery room stay he was discharged without any complications.
