Abstract

Dentinal hypersensitivity is a commonly occurring but less understood and poorly managed problem of the teeth. Iontophoresis is a technique wherein desensitizing agents can be transferred under electrical pressure into the tooth structure to manage hypersensitivity. The purpose of present study is to compare the effect of different strengths of electrical current used for varying lengths of time, keeping the electrical dosage constant with the iontophoretic unit in the management of dentinal hypersensitivity. This study was conducted among the patients attending the Periodontal Department of the Government Dental College and Hospital, Patiala, Punjab, specifically complaining of tooth hypersensitivity. The Verbal Rating Scale (VRS) was used to record scores pre-, during, and post-treatment. Ten percent SrCl2 solution was applied with an iontophoretic unit. Three applications were performed at weekly intervals, up to the second week, using the same electric current dosage. The data compiled was statistically analyzed. A remarkable reduction in dentinal hypersensitivity to both air blast and cold water stimuli was noted at the end of two months after iontophoresis with each current group/method, namely, I (0.25 mA for 4 minutes),...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
