Pain in children’s milk teeth caused by extensive decay: we examine the best ways to treat the dental pulp

Tooth decay is one of the most common diseases in children. Tooth decay in the primary or milk teeth tends to progress rapidly, and it often reaches the pulp. Dental pulp consists of nerves, tiny blood vessels and connective tissue that make up the centre of a tooth. Symptoms of this extensive tooth decay include pain, swelling and abnormal tooth movement.

Dentists often have to perform one of three pulp treatment techniques to resolve the problem:

  1. Direct pulp capping: where a healing agent is placed directly over the exposed pulp. The most common materials used for direct pulp capping are calcium hydroxide, mineral trioxide aggregate, formocresol or an adhesive resin, placed directly over the tooth’s nerve.
  2. Pulpotomy: removal of a portion of the pulp. After a pulpotomy, one of four materials is generally used to fill the cavity: ferric sulphate, formocresol, calcium hydroxide or mineral trioxide aggregate.
  3. Pulpectomy: removal of all of the pulp in the pulp chamber and root canal of a tooth. After a pulpectomy, a material is put into the space created by pulp removal.

This review looks at the three techniques, and the effectiveness of different materials (known as medicaments) for pulp capping, pulpotomy and pulpectomy. Continue reading
