Desensitizing toothpastes containing potassium nitrate have been used since the 1980s while toothpastes with potassium chloride or potassium citrate have been available since at least 2000. It is believed that potassium ions diffuse along the dentinal tubules to inactivate interdental nerves. Desensitizing agents are used in the treatment of dentin hypersensitivity, which is defined as a painful response in the exposed dentin to stimuli that are thermal, evaporative, tactile, osmotic, or chemical. • 2. Desensitizing agents include toothpastes, mouthwashes or chewing gums and they act by either occluding the dentinal tubules or blocking the neural transmission. • 3. Sensodyne offers a range of toothpastes for sensitive teeth pain relief, with stannous fluoride or potassium nitrate as a desensitizing ingredient. • Zinc oxide-eugenol cement • 1. Zinc oxide-eugenol cement (IRM) is a low-strength base used as a temporary cement filling in the event that the patient will return at a later date for a semi-permanent restoration. The powder is mainly zinc oxide and the liquid is eugenol with olive oil as a plasticizer. • 2. Zinc oxide/eugenol cements are mixtures of zinc oxide (powder) and eugenol (liquid). They are mainly used as a lining or base under amalgam restorations and as temporary luting cements or filling materials. • 3. ZOE can be used as a dental filling material or dental cement in dentistry. It is often used in dentistry when the decay is very deep or very close to the nerve or pulp chamber. • Get in touch with the solution by just clicking the following links- • Facebook Group- / solutionpharamcy • Mobile App - https://play.google.com/store/apps/de... • New Channel (Pharmacy Dictionary) / @pharmacydictionary • E-Mail for official and other work - [email protected] • #solutionpharmacy #Pharmacologyclass #Pharmacognosyvideos #GPAT
