Evaluation of the efficacy of nitrous oxide inhalation sedation on anxiety and pain levels of patients undergoing endodontic treatment in a vital tooth: A prospective randomized controlled trial.

Context: Anxiety and fear of pain are the two major deterrents for which patients avoid dental treatment. Local anesthetic, which forms the foundation for the delivery of pain-free endodontic treatment, does not serve the purpose in anxious patients and requires augmentation with other pharmacological agents.

Aims: The aim of this study is to observe the effectiveness of nitrous oxide in alleviating patient anxiety and pain during endodontic treatment of a vital tooth.

Topographic assessment of human enamel surface treated with different topical sodium fluoride agents: Scanning electron microscope consideration.

Introduction: Continuous balanced demineralization and remineralization are natural dynamic processes in enamel. If the balance is interrupted and demineralization process dominates, it may eventually lead to the development of carious lesions in enamel and dentine. Fluoride helps control decay by enhancing remineralization and altering the structure of the tooth, making the surface less soluble.

Comparative evaluation of diffusion hypoxia and psychomotor skills with or without postsedation oxygenation following administration of nitrous oxide in children undergoing dental procedures: A clinical study.

Background: Diffusion hypoxia is the most serious potential complication associated with nitrous oxide. It occurs during the recovery period. Hence, administration of 100% oxygen is mandatory as suggested by many authors.
