Oral sedation dentistry is a medical procedure involving the administration of sedative drugs via an oral route, generally to facilitate a dental procedure and reduce patients anxiety related to the experience. Oral sedation is one of the available methods of conscious sedation dentistry, along with inhalation sedation (e.g., nitrous oxide) and conscious intravenous sedation.[ citation needed ] Benzodiazepines are commonly used, specifically triazolam. [1] Triazolam is commonly selected for its rapid onset and limited duration of effect. [1] An initial dose is usually taken approximately one hour before the dental appointment. [1] Treatment may include additional dosing on the night proceeding the procedure, to mitigate anxiety-related insomnia. [1] The procedure is generally recognized as safe, with the effective dosages being below levels sufficient to impair breathing. [2]
Dental patients with generalized anxiety, belonephobia (fear of needles and sharp instruments), prior dental trauma, or generalized fear of the dentist can take oral medication in order to reduce their anxieties. [3] A variety of single and incremental dose protocols are used to medicate the patient as early as the day before treatment. [4] Medication additionally helps reduce memory or the sights and smells of the dental office to avoid recall of any trauma. [5] The sedative effect allows more dentistry to be completed in fewer appointments as well as allowing complex procedures to be performed in less time. [6]
Drug characteristics must be carefully considered when choosing the appropriate medication. Matching factors, such as where the drug is metabolized and any underlying diseases requires a good medical history and thorough knowledge of the drug's characteristics. All risk factors, individual characteristics, and procedural complexities can be taken into account in order to provide the best drug choice.[ citation needed ]
Courses in Oral Sedation Dentistry are offered across North America at various dental schools and private organizations. The largest for-profit provider of dental sedation continuing education in North America is the Dental Organization for Conscious Sedation. Specialty courses are being taught in pediatric sedation, ACLS, IV Sedation and emergency preparedness.[ citation needed ] The largest not-for-profit organization that provides educational courses in oral sedation as well as IV sedation and general anesthesia is the American Dental Society of Anesthesiology. [7]
Education and training requirements to administer sedation vary by state. The ADA has set forth general sedation guidelines that have been adopted or modified by many states. There are typically dosing limitations involved with anxiolysis, usually a single dose the day of treatment not to exceed the maximum recommended dose (MRD) of the medication in order to achieve the intended level of sedation. However, these sedation laws vary from state to state. Anxiolysis protocols are designed to treat healthy ASA I & II patients ages 18 and up for one to four hours of treatment. Some states now require a permit even for nitrous oxide administration and/or anxiolysis.[ citation needed ]
The main advantages of oral sedation[ citation needed ] versus other sedation methods are:
An anxiolytic is a medication or other intervention that reduces anxiety. This effect is in contrast to anxiogenic agents which increase anxiety. Anxiolytic medications are used for the treatment of anxiety disorders and their related psychological and physical symptoms.
Benzodiazepines, colloquially called "benzos", are a class of depressant drugs whose core chemical structure is the fusion of a benzene ring and a diazepine ring. They are prescribed to treat conditions such as anxiety disorders, insomnia, and seizures. The first benzodiazepine, chlordiazepoxide (Librium), was discovered accidentally by Leo Sternbach in 1955, and was made available in 1960 by Hoffmann–La Roche, which followed with the development of diazepam (Valium) three years later, in 1963. By 1977, benzodiazepines were the most prescribed medications globally; the introduction of selective serotonin reuptake inhibitors (SSRIs), among other factors, decreased rates of prescription, but they remain frequently used worldwide.
Hypnotic, or soporific drugs, commonly known as sleeping pills, are a class of psychoactive drugs whose primary function is to induce sleep and to treat insomnia (sleeplessness).
Sedation is the reduction of irritability or agitation by administration of sedative drugs, generally to facilitate a medical procedure or diagnostic procedure. Examples of drugs which can be used for sedation include isoflurane, diethyl ether, propofol, etomidate, ketamine, pentobarbital, lorazepam and midazolam.
Temazepam, sold under the brand name Restoril among others, is a medication of the benzodiazepine class which is generally used to treat severe or debilitating insomnia. It is taken by mouth. Temazepam is rapidly absorbed, and significant hypnotic effects begin in less than 30 minutes and can last for up to eight hours. Prescriptions for hypnotics such as temazepam have seen a dramatic decrease since 2010, while anxiolytics such as alprazolam, clonazepam, and lorazepam have increased or remained stable. Temazepam and similar hypnotics, such as triazolam (Halcion) are generally reserved for severe and debilitating insomnia. They have largely been replaced by z-drugs and atypical antidepressants as first line treatment for insomnia.
Lorazepam, sold under the brand name Ativan among others, is a benzodiazepine medication. It is used to treat anxiety, trouble sleeping, severe agitation, active seizures including status epilepticus, alcohol withdrawal, and chemotherapy-induced nausea and vomiting. It is also used during surgery to interfere with memory formation and to sedate those who are being mechanically ventilated. It is also used, along with other treatments, for acute coronary syndrome due to cocaine use. It can be given orally, transdermal, intravenously (IV), or intramuscularly When given by injection, onset of effects is between one and thirty minutes and effects last for up to a day.
A sedative or tranquilliser is a substance that induces sedation by reducing irritability or excitement. They are CNS depressants and interact with brain activity causing its deceleration. Various kinds of sedatives can be distinguished, but the majority of them affect the neurotransmitter gamma-aminobutyric acid (GABA). In spite of the fact that each sedative acts in its own way, most produce relaxing effects by increasing GABA activity.
Triazolam, sold under the brand name Halcion among others, is a central nervous system (CNS) depressant tranquilizer of the triazolobenzodiazepine (TBZD) class, which are benzodiazepine (BZD) derivatives. It possesses pharmacological properties similar to those of other benzodiazepines, but it is generally only used as a sedative to treat severe insomnia. In addition to the hypnotic properties, triazolam's amnesic, anxiolytic, sedative, anticonvulsant, and muscle relaxant properties are pronounced as well.
Flurazepam is a drug which is a benzodiazepine derivative. It possesses anxiolytic, anticonvulsant, hypnotic, sedative and skeletal muscle relaxant properties. It produces a metabolite with a long half-life, which may stay in the bloodstream for days. Flurazepam was patented in 1968 and came into medical use the same year. Flurazepam, developed by Roche Pharmaceuticals, was one of the first benzodiazepine hypnotic medications to be marketed.
Nonbenzodiazepines, sometimes referred to colloquially as Z-drugs, are a class of psychoactive, depressant, sedative, hypnotic, anxiolytic drugs that are benzodiazepine-like in uses, such as for treating insomnia and anxiety.
Loprazolam (triazulenone) marketed under many brand names is a benzodiazepine medication. It possesses anxiolytic, anticonvulsant, hypnotic, sedative and skeletal muscle relaxant properties. It is licensed and marketed for the short-term treatment of moderately-severe insomnia.
Chlordiazepoxide, trade name Librium among others, is a sedative and hypnotic medication of the benzodiazepine class; it is used to treat anxiety, insomnia and symptoms of withdrawal from alcohol, benzodiazepines, and other drugs.
Delorazepam, also known as chlordesmethyldiazepam and nordiclazepam, is a drug which is a benzodiazepine and a derivative of desmethyldiazepam. It is marketed in Italy, where it is available under the trade name EN and Dadumir. Delorazepam (chlordesmethyldiazepam) is also an active metabolite of the benzodiazepine drugs diclazepam and cloxazolam. Adverse effects may include hangover type effects, drowsiness, behavioural impairments and short-term memory impairments. Similar to other benzodiazepines delorazepam has anxiolytic, skeletal muscle relaxant, hypnotic and anticonvulsant properties.
Alcohol detoxification is the abrupt cessation of alcohol intake in individuals that have alcohol use disorder. This process is often coupled with substitution of drugs that have effects similar to the effects of alcohol in order to lessen the symptoms of alcohol withdrawal. When withdrawal does occur, it results in symptoms of varying severity.
Dental fear, or dentophobia, is a normal emotional reaction to one or more specific threatening stimuli in the dental situation. However, dental anxiety is indicative of a state of apprehension that something dreadful is going to happen in relation to dental treatment, and it is usually coupled with a sense of losing control. Similarly, dental phobia denotes a severe type of dental anxiety, and is characterised by marked and persistent anxiety in relation to either clearly discernible situations or objects or to the dental setting in general. The term ‘dental fear and anxiety’ (DFA) is often used to refer to strong negative feelings associated with dental treatment among children, adolescents and adults, whether or not the criteria for a diagnosis of dental phobia are met. Dental phobia can include fear of dental procedures, dental environment or setting, fear of dental instruments or fear of the dentist as a person. People with dental phobia often avoid the dentist and neglect oral health, which may lead to painful dental problems and ultimately force a visit to the dentist. The emergency nature of this appointment may serve to worsen the phobia. This phenomenon may also be called the cycle of dental fear. Dental anxiety typically starts in childhood. There is the potential for this to place strains on relationships and negatively impact on employment.
Twilight anesthesia is an anesthetic technique where a mild dose of sedation is applied to induce anxiolysis, hypnosis, and anterograde amnesia. The patient is not unconscious, but sedated. During surgery or other medical procedures, the patient is under what is known as a "twilight state", where the patient is relaxed and "sleepy", able to follow simple directions by the doctor, and is responsive. Generally, twilight anesthesia causes the patient to forget the surgery and the time right after. It is used for a variety of surgical procedures and for various reasons. Just like regular anesthesia, twilight anesthesia is designed to help a patient feel more comfortable and to minimize pain associated with the procedure being performed and to allow the medical practitioner to practice without interruptions.
Sedation dentistry refers to the use of pharmacological agents to induce relaxation and often sleep in a patient prior to and during a dental appointment. The pharmacological agents used differ depending on patient, level of sedation desired and medical professional administering the sedation medications. The medications can belong to a class of drugs called sedatives, which exert their action by depressing the central nervous system, specifically those areas concerned with conscious awareness. Medications used to obtain sedation often include a benzodiazepine, opioids, dissociative and anti-histamines.
In periodontics, there are four reasons to seek medication. Those four reasons include infection, swelling, pain, and sedation. Although some patients may experience pain, swelling, and infection as a result of an acute periodontal problem such as advanced periodontal disease, periodontic patients usually do not need medication until they are faced with surgery. For successful surgery, medication is then introduced prior to the operation, usually the morning before the procedure and is continued for up to two weeks after.
An anxiotropic agent is one that modifies anxiety, a human emotion that has homologous processes in animals. In psychopharmacology anxiotropic agents consist of two categories of psychoactive drugs: anxiolytics that reduce anxiety and may be used therapeutically, and anxiogenic compounds that increase anxiety.
