What is formocresol in dentistry?

Formocresol is a mixture consisting of formalin, cresol and glycerine used in dentistry. It is used for vital pulpotomy of primary teeth and as a temporary intracanal medicament during root canal therapy. Buckley’s solution is a 20% form of formocresol, diluted with glycerine and distilled water.

How do you use formocresol dental?

Moisten a small cotton pellet with formocresol. Blot or wring any excess liquid from the pellet. Place the cotton pellet in the pulp chamber and seal the access hole with a temporary filling material. Recall the patient after a minimum of 48 hours and remove the pellet.

Is formocresol still used in dentistry?

Ironically, formocresol pulpotomy is still the most frequently used procedure for asymptomatic caries that endangers the pulp chamber in primary teeth.

What is the purpose of formocresol?

Formocresol was first used as a root canal medication by Buckley in 1904. It is widely used in dentistry because of its antibacterial properties in root canal disinfection. [12] It contains formaldehyde, an effective alkylating agent, and cresol, a protein-coagulating phenolic compound.

What does formocresol do to pulp?

Formocresol has two major actions within the pulp. It kills bacteria, making it bactericidal, but it also fixes the pulp material, making it inert. Authors of the study in the Journal of Restorative Dentistry describe how the devitalizing action protects the pulp from enzyme breakdown.

What is formocresol made of?

1. DESCRIPTION. Formocresol: 48.5% formaldehyde, 48.5% cresol, 3% glycerine. Buckley’s Formocresol: 19% formaldehyde, 35% cresol, 17.5% gylcerine.

Is formocresol a hemostatic agent?

Formocresol, a once popular pulpotomy agent in primary teeth, has several side effects [3]. SH is a hemostatic agent and can probably be used in pulpotomy of primary teeth [11].

What can be used instead of formocresol?

Formocresol has a long history of clinical success, but concern exists regarding its safety as a medicament for primary molar pulp therapy. Alternatives have been proposed: calcium hydroxide, with relatively poor outcome and glutaraldehyde, which has shown better success rates than the former.

Is formocresol a fixative?

101 Formocresol presumably fixes affected and/or radicular tissue so that a chronic inflammation replaces an acute inflammation.

Why is formocresol used in pulpotomy?

Formocresol and ferric sulfate have been used as protective medicaments for partial or complete pulpotomy procedures, among other techniques, including electrosurgery and laser cautery. Ferric sulfate and formocresol staunch the bleeding pulp, but neither material is bioactive.

How long is formocresol pulpotomy?

A base of zinc oxide-eugenol cement mixed with paraformaldehyde and restoration was placed in second visit. A few years later Redig reported the clinical success of a 5-minute formocresol application, and since then, the 5-minute formocresol pulpotomy protocol became the standard practice for pulpotomy.

What is formocresol used for in pulpotomy?

Formocresol in dentistry. Hand-picking studies that have aberrant or inconclusive results when weighed against the accepted evidence becomes self-serving while simultaneously destructive to clinicians seeking the best for their patients.

Do Pediatric Dentists use formocresol to perform pulpotomies?

This investigation surveyed practicing pediatric dentists about the concentration of formocresol that they use to perform pulpotomies and, if they use diluted formocresol, where they obtain it. Eight-hundred-and-six surveys were sent to a randomly selected sample of practicing pediatric dentists, and 422 were returned for a 52% response rate.

Are there alternatives to formocresol as a pulp dressing in primary tooth pulpotomies?

In summary, the search for alternatives to formocresol as a pulp dressing in primary tooth pulpotomies has yet to reveal an ideal agent or technique. Until such an agent is found, formocresol (either in a one-fifth dilution or full strength), FS, or MTA can be used as capping agents in primary tooth pulpotomies. 147

How do you apply formocresol?

Formocresol is applied to the pulpotomy site on a cotton wool pledget. Any excess material should be blotted off the pledget prior to application. Traditionally, a 5-min application time has been recommended; however, contact times of only a few seconds are probably equally effective.
