Formaldehyde is an important intermediate in normal cellular metabolism. Care must be taken to ensure that all the coronal pulp tissue has been removed. 0000029800 00000 n A recent systematic review and meta-analysis concluded that pulpotomies performed with either formocresol or FS in primary molars have similar clinical and radiographic success, and that FS may be recommended as a suitable replacement for formocresol.122 Based in these studies, FS can still be an appropriate and inexpensive solution for pulpotomies in primary teeth. At issue was the previous pediatric dentistry specialist's recomme… The purpose of this article is to facilitate performance of the stainless steel crown and pulpotomy procedures in order to save chair time and provide a more durable and reliable final restoration for primary molars. The reparative, biologic approach to pediatric pulp therapy is either devitalization approach of formocresol pulptomy or pulpectomy. Pulpitis is the inflammation of the pulp and its main cause is untreated cavities (tooth decay). In assessing the potential risks of using formocresol clinically, however, it is important to consider the pharmacokinetics of formaldehyde. 0000003491 00000 n Mandibular first and second primary molars 36 months after pulpotomy with mineral trioxide aggregate. In a preliminary study comparing MTA with formocresol, with follow-ups ranging from 6 to 30 months, none of the MTA-treated teeth showed a clinical or radiographic pathologic process. Consequently, great interest has been focused on the evolution of PC as an alternative to MTA, and several experimental studies have compared both materials. trailer << /Size 74 /Info 21 0 R /Root 25 0 R /Prev 75904 /ID[<84a281d72cb2ac2633164cd28a2aad44><4edc8a433230695010970e7a2b79feac>] >> startxref 0 %%EOF 25 0 obj << /Type /Catalog /Pages 23 0 R /Metadata 22 0 R >> endobj 72 0 obj << /S 199 /Filter /FlateDecode /Length 73 0 R >> stream Electrical and Formocresol Pulpotomy in Primary Molars The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Pulpotomy is the term for removal of the coronal pulp with the intent of maintaining the vitality of the remaining radicular pulp tissue.54 Pulpotomy techniques using formocresol on primary teeth have been a standard in pediatric dentistry for decades. Next, Astringedent is flushed from the pulp chamber with water. 0000027057 00000 n Following coronal pulp amputation, one or more cotton pellets should be placed over each amputation site, and pressure should be applied for a few minutes. Preliminary studies have investigated the use of 5% sodium hypochlorite (NaOCl) as a primary molar pulpotomy agent. Endogenous formaldehyde is present at low levels in body fluids, with a concentration of 2–3 mg/L in human blood. These teeth were followed up from 6 to 35 months. 0000001784 00000 n It serves as a building block for the synthesis of purines, pyrimidines, many amino acids and lipids, and is a key molecule in one-carbon metabolism. The clinically and radiographically determined success rates were 96% and 84%, respectively, for the electrosurgical group, and 100% and 92%, respectively, for the formocresol group. All formaldehyde preparations are potent toxins with an antimicrobial effectiveness much lower than their toxicity.371,372. In all 4 groups, a polymer-reinforced zinc oxide–eugenol material was placed in the pulp chamber, and the teeth were restored with stainless steel crowns. The roof of the pulp chamber should be removed by joining the pulp horns with bur cuts. MTA paste is applied to cover the exposed radicular pulp surface with a margin of not less than 1 mm beyond the pulp dentin interface. I Formocresol was introduced to treat non-vital permanent teeth in the United States by Buckley in 1904. The wide acceptance of formocresol owes to factors like ease of use and excellent bactericidal properties. 0000002193 00000 n Tricresol formalin, another formaldehyde preparation, contains 10% tricresol and 90% formaldehyde. A radiograph of two primary molars treated with MTA is presented in Fig. Such signs indicate that the tooth is not a good candidate for formocresol pulpotomy, and pulpectomy or extraction should be done. formocresol,8 and iodoform pastes9 belong to this category and remained popular for decades. Formocresol is regarded as the ‘gold standard’ (King et al. In the same study sample at 42 months follow-up, the authors noted that 45% of the teeth that underwent pulpotomy with GA resorbed faster than their controls.109. Furthermore, the histologic response of the primary radicular pulp to formocresol appears to be unfavorable. It is unlikely that formocresol, when used in the doses typically employed for a vital pulpotomy procedure, poses any risk to children. (D) The tooth is restored with a stainless steel crown. Its efficacy has been extensively studied, with clinical success rates ranging from 70% to 100%, making it the standard against which newer techniques are compared. The apical third of the pulp is said to be unaffected, and remains vital for an extended period of time.6 The technique of applying formocresol in the pulpotomy on a Following hemostasis, a cotton pellet moistened with Buckley solution (full concentration or one-fifth solution) is placed over the pulp stumps for 5 minutes. Jeffrey A. 4 cotton pellet that has been squeezed dry, is approximately 0.02– 0.10 mg. Since the material cannot be kept once the envelope is opened, its clinical use in pediatric dentistry practice becomes almost prohibitive. When MTA was first commercialized, it had a gray coloration; but in 2002 a new white formula was created to improve on the dark color properties exhibited by the gray preparation. Listing a study does not mean it has been evaluated by the U.S. Federal Government. 0000050707 00000 n Guelmann and colleagues95 analyzed the success rates of emergency pulpotomies in primary molars. Sweet’s original methodology called for the procedure to be accomplished over multiple appointments, where the formocresol was left in contact with the radicular tissue for long periods of time (2-3 days)(9). Formocresol is applied to the pulpotomy site on a cotton wool pledget. Direct pulp capping showed similar success rates to IPT and MTA or FC pulpotomies, but the quality of evidence was lower.” The comparable success rates for all three vital pulp therapy techniques (IPT, DPC, and pulpotomy) provide more latitude in treatment choices for the practitioner in managing a vital primary tooth with deep caries. PubMed CrossRef Google Scholar A recent study142 compared the success rates of PC, MTA, formocresol, and enamel matrix derivative in primary molar pulpotomies and found similar clinical and radiographic effectiveness after 24 months. Both the ferric sulfate and sodium hypochlorite solutions were rinsed off with water to verify that no blood clot was present before restoration. Int J Paediatr Dent 2005;15: 437–447. Clinical trials show that MTA performs equal to or better than formocresol or ferric sulfate 8,11,57-61 and may be the preferred pulpotomy agent in the future. A 39-month-old girl was brought in by her mother to receive a second opinion regarding treatment for a severe occlusal caries lesion on her mandibular right primary second molar (Figure 1).

Formocresol has been used in dentistry for over 100 years, and for vital pulpotomy in primary teeth for over 80 years. 0000028698 00000 n Mandibular second primary molar presenting internal root resorption following pulpotomy with ferric sulfate.
