Comparative evaluation of different strengths of electrical current in the management of dentinal hypersensitivity.

Background: 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.

Aim: 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.

Duration of reappearance of gingival melanin pigmentation after surgical removal - A clinical study.

Background: In dentistry, esthetics has a special place. Although gingival melanin pigmentation does not present a medical problem, clinicians are often faced with a challenge of achieving gingival esthetics.

Materials And Methods: A method of de-epithelialization of the pigmented gingiva using Kirkland's gingivectomy knife is described.
