Electrical and Formocresol Pulpotomy in Primary Molars The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Results: One hundred ninety-two NaOCl primary molar pulpotomies were completed in 118 patients; 131 (68%) primary molars from 77 children were available for follow-up examination (mean time since pulpotomy=10.5 months). 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. The short-term success of 2% GA as a pulpotomy agent has been demonstrated in several studies.106–111 However, longer-term success rates matching those of formocresol have not been reported. Care must be taken to ensure that all the coronal pulp tissue has been removed. Such signs indicate that the tooth is not a good candidate for formocresol pulpotomy, and pulpectomy or extraction should be done. 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. 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. Areas listed initially as internal resorption on the preliminary report remained unchanged after 30 months, and thus were reassessed as normal in the last evaluation (Fig. In both cases, very little or no hemorrhage is present. Tags of tissue remaining under ledges of dentin may continue to bleed, masking the actual status of the radicular pulp stumps and thus obscuring a correct diagnosis (Fig. This solution is prepared by making a diluent of three parts glycerin and one part water. Before local anesthesia administration, a thorough clinical examination should be repeated, including visual examination of the vestibulum, palpation, and percussion of the involved and neighboring teeth. Pulpitis is the inflammation of the pulp and its main cause is untreated cavities (tooth decay). 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. An evidence-based proven alternative to formocresol with reported success rates equal and even surpassing those of formocresol and all other pulpotomy agents is MTA.127 MTA was developed by Torabinejad at Loma Linda University in the 1990s, first described in the dental scientific literature by Lee and colleagues128 in 1993, and approved by the FDA in 1998. 0000002934 00000 n 0000050707 00000 n 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. Formocresol is still the most used medicament for dental pulp therapy in primary teeth despite potential safety concerns over its primary ingredient, formaldehyde. Figure 23.15. A pilot study by Vargas and colleagues123 showed promising results after a 12-month period, and a retrospective study124 confirmed these findings. Despite this, formocresol continues to be a very commonly used pulpotomy medicament.15 Indeed, Milnes’ reevaluation of earlier and more recent research about formaldehyde metabolism, pharmacokinetics, and carcinogenicity led him to suggest that there is an inconsequential risk associated with the use of formocresol in pediatric pulp therapy.16 The pulp chamber is dried with sterile cotton pellets. The formaldehyde component of formocresol is strongly bactericidal and reversibly inhibits many enzymes in the inflammatory process. (B) After hemostasis and formocresol application, the tissue at the entrance of the canals shows dark color, a sign of tissue fixation. It is beyond the scope of this chapter to elaborate on these newer and still experimental techniques, but the reader is encouraged to look for future developments in the field. Holan and coworkers94 observed that pulpotomized primary molars could be successfully restored with one-surface amalgams if their natural exfoliation is expected within 2 years or less. 0000027301 00000 n Four parts of this diluent are then mixed with one part Buckley solution to make the one-fifth dilution. Although this method of application saved time, it rendered the pulp tissue only partially vital leaving the tissue susceptible to abscess formation and/or internal root resorption . Excessive bleeding that persists in spite of cotton pellet pressure and a deep purple color of the tissue may indicate that the inflammation has extended to the radicular pulp. 0000042171 00000 n An excellent prospective randomized clinical trial was conducted by Fernandez and others,18 comparing the use of formocresol, MTA, sodium hypochlorite, and ferric sulfate. 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. 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. 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. If your child complains of pain when cold, hot or sweet things touch their tooth/teeth, it may mean that he/she has pulpitis. Formocresol has been used in dentistry since 100 years and for deciduous teeth pulpotomy since 80 years. Jeffrey A. 0000003491 00000 n 0000026248 00000 n One year after treatment, the success rate for teeth in the experimental group was 89%, whereas the success rate in the control group was 68%. Internal resorption was the most common radiographic finding up to 24 months after pulpotomy. (C) The pulps stumps are covered by a zinc oxide–eugenol base. 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). Age factor The children’s age at time of treatment is summarized in Table 3. Rivera and colleagues71 obtained results similar to those of Dean and associates; however, Fishman and colleagues72 found considerably lower success rates with the use of electrosurgical pulpotomy. 0000043727 00000 n The reparative, biologic approach to pediatric pulp therapy is either devitalization approach of formocresol pulptomy or pulpectomy. The gray MTA had 100% radiographic success, and the white had a 93% success rate. Formocresol has been used in dentistry for over 100 years, and for vital pulpotomy in primary teeth for over 80 years. 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 Clinicians need to be aware of the risks in using any medicament or equipment, use each according to the manufacturers' directions and be familiar with relevant Material Safety Data Sheets. A case of a deep subgingival fracture treated with a formocresol pulpotomy is illustrated in Figure 3-9. The postoperative observation time ranged from five … In these cases, a coronal pulpotomy may be indicated. The roof of the pulp chamber should be removed by joining the pulp horns with bur cuts. The Cox-regression analysis revealed that patient's age at the time of pulpotomy impacted the "hazard of exfoliation." Formaldehyde-containing materials, e.g. Ralph E. McDonald, ... Jeffrey A. 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. PubMed CrossRef Google Scholar This review demonstrated that the “highest level of success and quality of evidence supported IPT and the pulpotomy techniques of MTA and FC for the treatment of deep caries in primary teeth after 24 months. Originally, the aim of using formocresol was to completely mummify (fix) all residual pulpal tissue and necrotic material within the root canal. Excessive bleeding that persists in spite of cotton pellet pressure and a deep purple color of the tissue may indicate that the inflammation has extended to the radicular pulp. A second layer is then condensed to fill the access opening completely (see Fig. Pulp canal obliteration was detected in 13% of the teeth treated with formocresol and in 41% of those treated with MTA. 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. 0000046629 00000 n Nevertheless, amid the controversies and concerns, efforts have increased to find a substitute medicament. Fuks and associates107 reported a failure rate of 18% in human primary molars 25 months after pulpotomy, using a 2% concentration of GA. Phenol derivatives and iodine formulations gained popularity as medicaments in endodontics; sodium hypochlorite was confirmed as a suitable irrigant. 0000047348 00000 n sixty primary molars were either treated with Theracal LC or formocresol pulpotomy. The age range at the time of treatment was 32 to 126 months, with a mean treatment age of 68.2 months. Such signs indicate that the tooth is not a good candidate for, Glutaraldehyde (GA) has been proposed as an alternative to, Problem-Solving Challenges in Dentin Hypersensitivity and Vital Pulp Therapy, James L. Gutmann DDS, Cert Endo, PhD (honoris causa), FACD, FICD, FADI, Paul E. Lovdahl DDS, MSD, FACD, FADI, in, Problem Solving in Endodontics (Fifth Edition). In a preliminary report of the same study, a much lower success rate was described (77.5% for the FS group and 81% for the DFC teeth), with internal resorption evident in five teeth treated with FS and four teeth fixed with DFC.118 This discrepancy can be explained by an excessively severe interpretation of the initial findings. 0000030454 00000 n The mean age of the children at the time of treat- ment was 72(±21) months with a range of 24 to 147 months. A thick paste of hard-setting zinc oxide–eugenol is prepared and placed over the pulp stumps. 0000001347 00000 n When the cotton pellets are removed, hemostasis should be apparent, although a minor amount of wound bleeding may be evident (see Fig. 23.13A). A radiograph of two primary molars treated with MTA is presented in Fig. It is important to emphasize that the key to success, regardless of the clinician's choice of agents, is the prevention of marginal microleakage of the restoration, which could lead to bacterial contamination. 0000044351 00000 n CROWN FRACTURES: A PRACTICAL APPROACH FOR THE CLINICIAN, When the pulp exposure is very large or when more than 2 weeks have passed since the injury, contaminants may cause extensive infection or inflammation 2 to 3 mm beyond the exposure. On an empirical basis, some clinicians currently make the decision based on the amount of pulpal hemorrhage from the exposure. The systematic review and meta-analysis on primary tooth vital pulp therapy,74 mentioned previously, will be the evidence-based material to be used in the new Guideline for Pulp Therapy for Primary Teeth for the AAPD. Pulpotomy is a dental procedure used to save decayed, infected teeth. In these cases, a coronal pulpotomy may be indicated. Next, Astringedent is flushed from the pulp chamber with water.

WATERHOUSE, ... ANNA B. FUKS, in, Cohen's Pathways of the Pulp (Tenth Edition), Treatment of Deep Caries, Vital Pulp Exposure, and Pulpless Teeth, Ralph E. McDonald, ... Jeffrey A. This procedure was designed to mummify the tissue completely. Preliminary studies have investigated the use of 5% sodium hypochlorite (NaOCl) as a primary molar pulpotomy agent. 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. The MTA is prepared as per manufacturer's instructions. 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. Further studies with longer follow up period is needed to correlate the success rate with the follow up time after providing formocresol pulpotomy therapy. Newer bioactive cements such as Biodentine have been used as pulpotomy agents with promising results. 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. In all cases, if bleeding does not stop, then one should proceed to primary molar root canal therapy or extraction. A. O'Donnell, in Harty's Endodontics in Clinical Practice (Sixth Edition), 2010, Glutaraldehyde has been investigated as an alternative fixative to formocresol because of its lower toxicity.50 Glutaraldehyde is a larger molecule than formaldehyde, and as a result diffusion through the tissues is reduced. These teeth were followed up from 6 to 35 months. Glutaraldehyde (GA) has been proposed as an alternative to formocresol because it is a mild fixative and is potentially less toxic. 0000041361 00000 n 0000026602 00000 n Because of its cross-linking properties, penetration into the tissue is more limited, with less effect on periapical tissues. 0000046343 00000 n A recent 18-month follow-up randomized clinical study found similar results when Biodentine was compared with ProRoot MTA.143, Nonpharmacotherapeutic approaches to pulpotomy include the treatment of radicular pulp tissue by electrocautery or laser to eliminate residual infectious processes. Mandibular second primary molar presenting internal root resorption following pulpotomy with ferric sulfate. Formocresol Formocresol has been used in dentistry since 100 years and for deciduous teeth pulpotomy since 80 years. Indeed, a Cochrane review141 concluded that among possible pulpotomy agents, two medicaments may be preferable: MTA or formocresol. They reported a 99.4% success rate (one failure) for this pulpotomy technique. When using FS, the amputated pulps at the canal orifices are wiped with 15.5% solution of FS (Astringedent) for 10 to 15 seconds. Although the formocresol pulpotomy technique has been recommended for many years as the principal method for treating primary teeth with carious exposures, a substantial shift away from use of this medicament has occurred because of concerns about its toxic effects. Because formocresol is caustic, care must be taken to avoid contact with the gingival tissues. 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. This procedure should be done carefully to prevent further damage to the pulp and perforation of the pulpal floor. Consequently, great interest has been focused on the evolution of PC as an alternative to MTA, and several experimental studies have compared both materials. Another interesting finding was that gray MTA showed a significantly higher number of dentine bridge formation than white MTA. 0000044330 00000 n 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). 0000049843 00000 n 0000027057 00000 n No intrapulpal local anesthesia or other hemostatic agent should be used to minimize hemorrhage, because bleeding is a clinical indicator of the radicular pulp status. and strong, caustic antiseptics were popular as intracanal medicaments at the turn of the twentieth century. Rolling and Thylstrup99 demonstrated that its clinical success rate decreased as follow-up time increased. 0000046290 00000 n 0000031019 00000 n By continuing you agree to the use of cookies. formocresol,8 and iodoform pastes9 belong to this category and remained popular for decades. The area remained unchanged for 30 months. Calcium hydroxide, while advocated since 1930,17 has gained popularity in endodontics in the last three decades. This tooth sensitivity is usually the first sign that your child may have caries.1 Your doctor will recommend that your child undergo a pulpotomy if, upon dental examination, it is discovered that your child has caries (tooth … At issue was the previous pediatric dentistry specialist's recomme… However, before routine clinical use of PC can be recommended, further studies with large samples and long follow-up assessments are needed. Pulpotomy technique steps. NaOCl pulpotomies had a 95% clinical … 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. The treatment is also completed during a single appointment. 0000002193 00000 n Furthermore, the histologic response of the primary radicular pulp to formocresol appears to be unfavorable. The coronal portion of the pulp should be amputated as described previously, the debris should be removed from the chamber, and the hemorrhage should be controlled. Formocresol should only be applied to the pulpotomy site after haemostasis has been obtained. Varying levels of success in early experimental studies have been reported with freeze-dried bone112 autolyzed, antigen-extracted, allogeneic dentin matrix113; allogeneic BMP,14 a fully synthetic nanocrystalline hydroxyapatite paste114; enriched collagen solutions115; and Biodentine, a calcium-silicate–based material.116 Clinical studies have reported promising results using FS, a hemostatic agent, in pulpotomized human primary teeth.117,118 Fuks and colleagues119 reported a success rate of 93% in teeth treated with FS and 84% in those where diluted formocresol (DFC) was employed. 0000028698 00000 n Since the material cannot be kept once the envelope is opened, its clinical use in pediatric dentistry practice becomes almost prohibitive. 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. Many alternatives, including MTA, sodium hypochlorite, ferric sulfate, electrosurgery, and lasers, have been investigated to replace formocresol as the medicament of choice for pulpotomy. Tricresol formalin, another formaldehyde preparation, contains 10% tricresol and 90% formaldehyde. The use of formocresol in dentistry falls within the current permitted exposure limits, and short-term exposure limits for formaldehyde. Formaldehyde is an important intermediate in normal cellular metabolism. 0000001991 00000 n 0000042932 00000 n Pulp canal obliteration is evident in the distal root of the second molar; both procedures were rated as successful. Formocresol is applied to the pulpotomy site on a cotton wool pledget. The other half (experimental group) received a calcium hydroxide cap after first undergoing CO2 laser radiation until the “exposed pulps were completely sealed.” The teeth were monitored monthly. The IARC has determined that silica is a known human carcinogen. The indication was primarily the presence of a carious exposure and desire to retain the primary tooth until exfoliation. Listing a study does not mean it has been evaluated by the U.S. Federal Government. However, if placing the final restoration is not possible, the ZOE base will serve as an acceptable interim restoration until the stainless steel crown can be placed. It has therefore been suggested that the findings should not be extrapolated to clinical use in humans.192,196,197 More recently, a review of the safety of formocresol, including FAD metabolism, suggested that FAD is rapidly metabolized, so the findings of previous studies may have been identifying FAD metabolites systemically and not FAD itself.182 Notwithstanding this, the amount of formocresol absorbed systemically by way of the pulpotomy route is small and may not contraindicate the use of the drug.220, ZVI METZGER, ... HAROLD E. GOODIS, in Cohen's Pathways of the Pulp (Tenth Edition), 2011, Formaldehyde, used as formocresol, has been used extensively in endodontic therapy despite its high toxicity and mutagenic and carcinogenic potential.221 The formaldehyde component of formocresol may vary substantially between 19% and 37%. 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 wide acceptance of formocresol owes to factors like ease of use and excellent bactericidal properties. Formocresol produces an area of necrosis in the adjacent pulp tissue with the fixative effect diminishing as it progresses apically. Each year following the completion of DFC or MTA pulpotomy, there is a 4.6-times-more-likely chance for early exfoliation of the pulpotomized tooth. Formaldehyde-containing materials, e.g. Next, a pellet of cotton moistened with a 1:5 concentration of Buckley’s formocresol and blotted on sterile gauze to remove the excess is placed in contact with the pulp stumps and allowed to remain for 5 minutes. Pulpotomy is defined as “the surgical removal of the coronal part of an exposed vital pulp as a means of maintaining the function and vitality of the remaining radicular pulp” [1]. Mandibular first and second primary molars 36 months after pulpotomy with mineral trioxide aggregate. In assessing the potential risks of using formocresol clinically, however, it is important to consider the pharmacokinetics of formaldehyde. Formaldehyde is volatile and releases antimicrobial vapors when applied to a cotton pellet for pulp chamber disinfection. 7-18).56 Research must still pursue the conditions in which a pulpotomy is the preferred treatment regimen rather than a direct pulp cap.
