The Impact of Nicotinic Receptors on Drug Therapies in Dentistry

Abstract

Nicotinic receptors  are seen in the central  nervous system ( CNS ), Peripheral  nervous  system  ,( PNS ) and neuro muscular junctions,  making them pivotal  in dental procedures that involve pain management,  anesthesia and muscle  relaxation.  Their interaction  with drugs can impact the efficacy  in a significant  manner and safety of dental treatments.  In dentistry, local anesthetics are frequently used to create a momentary numbness and lessen pain during procedures like root canal therapy and tooth extractions. These agents primarily perform by blocking sodium channels, thereby stopping nerve conduction.  During certain  dental procedures namely orthodontic adjustments or temporo mandibular joint ( TMJ ) treatments,  muscle relaxants may be administered to inhibit muscle spasms and improve manipulation. Dentist must consider the interaction  between muscle relaxants and nicotinic receptors to ensure optimal  outcomes ND minimize adverse effects. Pain management  is an important  aspect of dentistry, particularly  for procedures that may cause discomfort or post_ operative pain. Dentists need to evaluate individual patient factors along with nicotine exposure  as well as receptor sensitivity. Chronic nicotine  exposure  can lead to receptor desensitization and alterations in receptor density, potentially influencing the response to pharmacological interventions in dentistry. Incorporating knowledge  of nicotinic receptors  and their influence on drug therapy is responsible for dental practitioners to deliver safe and effective  care.  Finally  it is concluded that nicotinic receptors play an  important role in mediating the effects of drugs generally  used in dentistry  along with local anesthetics,  muscle relaxants and analgesics.
