While much has been written recently concerning the potential toxicity of formocresol, it should be noted also, that exposure to MTA dust and crystalline silica can cause respiratory irritation, ocular damage and skin irritation. When 2% unbuffered glutaraldehyde was used, over 96% clinical success was reported after 42 months.51,52 A 90% clinical success rate was reported after 1 year, where 2% buffered glutaraldehyde was applied for 5 minutes in pulpotomies.53 At follow-up after 2 years there was a failure rate of 18% as a result of internal resorption;54 the authors concluded that the relatively high failure rate reported in this study does not justify recommending a 2% buffered glutaraldehyde solution as a substitute to formocresol. Care must be taken to ensure that all the coronal pulp tissue has been removed. Background: Pulpotomy is an accepted treatment for the management of cariously exposed pulps in symptom free primary molars to achieve one of the most important goals for Pedodontists, which is the retention of the pulpally involved deciduous teeth healthy until the time of normal exfoliation. Dean, in McDonald and Avery Dentistry for the Child and Adolescent (Ninth Edition), 2011, The pulp response to formocresol has been compared with electrosurgical coagulation after pulpotomies in the teeth of monkeys by Ruemping and associates.67 The sample size was not large, and the observation periods were relatively short (maximum was 2 months after the operation), but the results of their histologic study showed the electrosurgical technique to be as favorable as the full-strength formocresol technique. If the hemorrhage is controlled readily and the pulp stumps appear normal, it may be assumed that the pulp tissue in the canals is normal, and it is possible to proceed with pulpotomy. All of these preparations have a formaldehyde content well above the 10% normally used for fixation of pathologic specimens. When using FS, the amputated pulps at the canal orifices are wiped with 15.5% solution of FS (Astringedent) for 10 to 15 seconds. 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. Few data are available to verify the optimal application time, although García-Godoy and colleagues have suggested that, based on their limited work with pulpotomies in dogs, a 1-minute application time may be adequate and perhaps superior to the recommended 5 minutes.17. It is a mixture of a refined Portland cement (PC), dicalcium silicate, tricalcium silicate, tricalcium aluminate, gypsum, and tetracalcium aluminoferrite; bismuth oxide is also added, making the material radiopaque. (A) Pulp chamber after coronal pulp amputation; wide access opening prevents leaving tissue tags. 0000031019 00000 n 0000028297 00000 n Internal root resorption, a finding seen both in FS- and DFC-treated teeth in other studies,119,121 was not observed in MTA-treated teeth in the preliminary report.130 Longer clinical studies have since been published with high success rates.131–137 Holan and associates138 investigated MTA effects in 33 pulpotomized molars during a median follow-up evaluation period of 38.2 months, reporting a success rate of 97%. A pilot study by Vargas and colleagues123 showed promising results after a 12-month period, and a retrospective study124 confirmed these findings. 0000026248 00000 n 0000011035 00000 n Pulpectomy is a procedure to save a severely damaged tooth; usually a baby tooth, and it can prevent problems with chewing, speech, and overcrowding that can … Figure 23.14. Mack and Dean reported the results of a retrospective human study of electrosurgical pulpotomies performed on primary molars.69 The mean postoperative observation time for the 164 teeth studied was 2 years, 3 months. It is prudent to limit both dose and contact time. formocresol,8 and iodoform pastes9 belong to this category and remained popular for decades. 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.

Although many studies have reported the clinical success of formocresol pulpotomies, an increasing body of literature has questioned the use of formocresol. The estimated formaldehyde dose associated with 1 pulpotomy procedure, assum- ing a 1:5 dilution of formocresol placed on a no. 0000045091 00000 n Because formocresol is caustic, care must be taken to avoid contact with the gingival tissues. Farsi and coworkers139 compared the effect of MTA in 60 pulpotomized molars with those of formocresol followed during 2 years and noted a success rate of 100%. Listing a study does not mean it has been evaluated by the U.S. Federal Government. 0000017808 00000 n 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. In both cases, very little or no hemorrhage is present. By continuing you agree to the use of cookies. A classic study claims that, subsequent to formocresol application, fixation occurs in the coronal third of the radicular pulp, chronic inflammation in the middle third, and vital tissue in the apical third.100 Others report that the remaining pulp tissue is partially or totally necrotic.101 Several reports have questioned the safety of formocresol,102,103 and most authorities now agree that formocresol is at least potentially mutagenic, carcinogenic, and toxic when used in high concentrations and under specific conditions in animal studies. 0000029072 00000 n This procedure should be done carefully to prevent further damage to the pulp and perforation of the pulpal floor. 0000001784 00000 n 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).

NaOCl pulpotomies had a 95% clinical … Application of formocresol results in systemic absorption of formaldehyde, however the absorbed formaldehyde is rapidly metabolized to formate and carbon dioxide with a half-life of 1–2 min. A surgically clean technique should be used. This course is designed for pediatric dentists and general dentists who want to update themselves on pulp therapy for the pediatric patients.

Formocresol is applied to the pulpotomy site on a cotton wool pledget. Both materials have comparable antibacterial activity and almost identical properties macroscopically, microscopically, and by x-ray diffraction analysis. In all cases, if bleeding does not stop, then one should proceed to primary molar root canal therapy or extraction. Shoji and colleagues reported the results of some preliminary studies on the treatment of amputated pulps (pulpotomies) in dogs by CO2 laser radiation.73 Wilkerson and colleagues reported favorable pulpal responses of healing and repair in swine following pulpotomies using an argon laser.74 Moritz and associates applied 200 direct pulp caps in adult patients after mechanical pulp exposures.75 Half of the teeth (control group) received a conventional calcium hydroxide pulp cap. 23.13B). Figure 23.13. Formocresol is regarded as the ‘gold standard’ (King et al. The reduction of pain through pharmacological control of the inflammatory process has also been attempted in endodontics by the application of eugenol,13 and later corticosteroids and other anti-inflammatory drugs,14 as dressings. In the formocresol group, the clinical and radiographic success rates were 100 percent and 92 percent, respectively. Many alternatives, including MTA, sodium hypochlorite, ferric sulfate, electrosurgery, and lasers, have been investigated to replace formocresol as the medicament of choice for pulpotomy. Although the recommendation is that the blotted cotton pellet moistened with a 1:5 concentration of formocresol be applied to the pulp stumps for 5 minutes, the 5-minute application time has been determined somewhat arbitrarily. The focus on the possible adverse toxic effects of medicaments15,16 led to a more systematic selection from the list of disinfectants available for use. However, a study has suggested that a 1-minute exposure to full-strength formocresol is sufficient and comparable in clinical success to the 5-minute technique.93 When the pellet is removed, the amputation site should appear dark brown (when a full concentration of formocresol is used) or dark red (when the one-fifth dilution is employed). The same diagnostic criteria recommended for the selection of permanent teeth for the pulpotomy procedure should be used in the selection of primary teeth for this procedure.
