Effect of Nitrous Oxide on the Efficacy of the Inferior Alveolar Nerve Block in Patients with Symptomatic Irreversible Pulpitis

Abstract

For mandibular teeth diagnosed with symptomatic irreversible pulpitis, administration of 30%-50% nitrous oxide resulted in a statistically significant increase in the success of the IAN block compared with room air/oxygen.

Assessment of Patients' Awareness and Factors Influencing Patients' Demands for Sedation in Endodontics

“…Inhalation sedation with nitrous oxide and oxygen and benzodiazepines such as midazolam can help with pain control when used in conjunction with local anesthesia (14,(28)(29)(30).…”

Effect of Buffered 4% Lidocaine on the Success of the Inferior Alveolar Nerve Block in Patients with Symptomatic Irreversible Pulpitis: A Prospective, Randomized, Double-blind Study

“…The mean initial pain ratings of 115-116 mm for both groups indicates severe pain on the VAS. This pain is representative of patients with symptomatic irreversible pulpitis (20,21,(23)(24)(25)(26)(27) who present for emergency endodontic treatment. We sampled a middle-aged population (mean age = 35 years).…”

“…Each patient also rated his or her initial pain on a HeftParker visual analog scale (VAS) (19). The VAS was divided into 4 categories as reported previously (20,21).…”

“…The VAS was divided into 4 categories as reported previously (20,21). It was emphasized that the satisfaction survey did not affect the operator's grades or standing in the residency so that patients were encouraged to be honest in their assessment.…”

Prevention and Treatment of IAN Injuries: A Literature Review

“…For preventing these events, restless patients and children should be premedicated to diminish anxiety and to decrease unnecessary accidents. Nitrous oxyde may constitute a useful method to control these cases, and would also help to obtaining a more effective nerve block even in cases of irreversible pulpitis [11].…”
