pulpectomy filling material

In the absence of rapidly progressing (inflammatory) root resorption, treatment is to obturate the canal with gutta-percha. A pulpectomy involves complete pulp tissue removal from the crown and root and is indicated when no vital tissue remains. After the pulp tissue has been removed from the canals, a syringe is used to irrigate them with 3% hydrogen peroxide followed by sodium hypochlorite. The main advantages of KRI paste compared with zinc oxide–eugenol paste are that KRI paste resorbs in synchrony with primary roots and is less irritating to surrounding tissues if a root is inadvertently overfilled.

Lasers provide a safe, effective, nonchemical alternative for pulpotomies.59,60 With more than 6 years of results on more than 5000 laser pulpotomies showing excellent results, the author can confirm the safety and effectiveness of this technique on children without using chemicals or electrosurgery (Figure 12-25). Roots of the primary teeth will begin to resorb as soon as the root length is completed. The subsequent deposition of secondary dentin throughout the life of the teeth caused a change in the morphologic pattern of the root canal, producing variations and eventual alterations in the numbers and sizes of the canals. J Indian Soc Pedo Prev Dent. In the strictest sense, complete removal of the the pulp from the pulp chamber and canals is a pulpectomy. The resulting space is then filled with special, medicated, dental materials, which while fill not allowing further maturation restore the tooth to its normal function. Disinfection with irrigating solutions is an important step in assuring optimal bacterial decontamination of the canals. The root canals are irrigated with either 0.2 % up to 2 % chlorhexidine solution or with 1 % up to 5 % sodium hypochlorite (limited to one percent sodium hypochlorite according to the AAPD guidelines) (Fig. A thick mix of ZOE (Zinc Oxide BP, Eugenol BP, Associated Dental Products Ltd, Purton, England) without setting accelerators may be pushed into the root canals using a suitable root canal plugger. Pulpectomy in deciduous teeth is a common procedure in dental practice, seeking to preserve function of the pulpally involved tooth. 19-13). An apexification procedure allowed this immature permanent tooth to be obturated successfully with gutta-percha (GP). 10. (C) Twenty-seven-month postoperative view. Vitapex can be used as a temporary or permanent root canal filling material after pulpectomy. The minimally invasive endodontic techniques of vital pulp therapy (VPT) are based on improved understanding of the capacity of pulp (nerve) tissues to heal and regenerate plus the availability of advanced endodontic materials. The optimum duration of the calcium hydroxide treatment is unknown, but generally calcium hydroxide should be kept in the canal for at least 6 months or until root end closure (apical plug) occurs beyond 1 year. In primary teeth with irreversible pulpal changes, ZOE pulpectomies yielded similar outcomes as Vitapex and more favorable than Sealapex, a calcium hydroxide cement (SybronEndo, Orange, CA), although there was no agreement with regard to filling materials’ resorption . (. Those that do respond favorably may still require root canal treatment several months later. Materials are inserted with a spiral lentulo mounted on a slow-speed engine, Insertion of paste with a plastic syringe, The ideal root canal filling material should resorb at the same pace as the physiologic resorption of the roots, be nontoxic to the periapical tissues and to the permanent tooth germ, resorbs readily if forced beyond the apex and be antiseptic, easy to insert, nonshrinkable, and easily removed if necessary [, A number of root canal filling materials can be used for primary teeth, with no known ideal root canal filling material. The file removes tissue only as it is withdrawn and penetrates readily with a minimum of resistance. Alternatively a Lentulo spiral file can be placed on an endodontic handpiece to spiral the filling material into the canals. Each canine tooth is cut off level with adjacent teeth, using tapering crosscut bars or Damascus separating disks (William Dixon, Inc., Carlstadt, New Jersey) attached to a dental drill. In cases in which an adjacent tooth is still unerupted, calcium hydroxide treatment is recommended until eruption of the adjacent tooth.55 It is believed that eruption may stimulate or accelerate the resorptive process in a nearby replanted root. The pulp filaments from the root canals are removed with a fine barbed broach; considerable hemorrhage will occur at this point. Moreover, adverse reactions are virtually certain if degenerating pulp tissue is allowed to remain in the canals for more than a few days. Primary molar roots are usually curved to allow for the development of the succedaneous tooth. It’s usually performed on baby teeth. In the case of pulpal involvement when the root is incompletely formed, a pulpotomy followed by placement of an appropriate restoration is indicated. They may be opened for drainage and often remain asymptomatic for an indefinite period. Contraindications for RCT in primary teeth are discussed lengthily in the literature [, Lateral and accessory canals exist in most primary molars and are more prevalent in mandibular molars compared with maxillary ones [, A RCT in a primary second molar with a poor prognosis is sometimes indicated, even if that tooth is maintained only until the first permanent molar has erupted, and then the primary molar is extracted and replaced with a space maintainer [. evaluated clinically and radiographically a mixture of zinc oxide eugenol and aloe vera as an obturating mate- rial for Pulpectomy in a total of 15 primary molars for a period of 9 months.The incidence of pain present preoperatively reduced to 86.67% postoperatively. When tooth fracture or caries involves the pulp and root development is complete, a routine pulpectomy and gutta-percha root canal filling should be completed. Alternatives: Pulpotomy may be accomplished if indicated (p. 124), or the tooth may be extracted, followed by placement of a space maintainer (p. 128). The pulp should be extirpated before the splint is removed, however, and preferably within 1 week after the injury. Materials used in pulpotomy dressing usually affect the success rate of pulpotomy. Treatment is considered a failure when preexisting radiolucent defects have grown in size or new defects appeared. The primary components of KRI paste are zinc oxide and iodoform. Further condensation may be carried out if required. The reader is referred to standard endodontic textbooks for more information on this technique. The following paragraph describes several commonly used root canal filling materials. The pulp should be extirpated when the first signs of degeneration appear. S. en C.S. Although zinc oxide–eugenol paste is viewed as the traditional root canal filling material for primary teeth, multiple studies18–23 suggest that KRI paste (Pharmachemie AG, Drusberstr. Metapex (Meta Biomed Co., Ltd. Cheongju City, Korea): calcium hydroxide with iodoform, Kri paste(Pharmachemie AG, Switzerland): iodoform (80.8 %), camphor, parachlorophenol, menthol, Maisto’s paste: zinc oxide and iodoform, with parachlorophenol camphor, lanolin, and thymol, Endoflas (Sanlor & cfa. This procedure involves anesthetizing the animal, in this case a nonhuman primate, and placing it on a surgery table in dorsal recumbency. The root canals are first irrigated with either 0.2 % up to 2 % chlorhexidine solution or with 1 % up to 5 % sodium hypochlorite and then with normal saline, The use of sodium hypochlorite in the primary dentition should be performed cautiously since it is a potent tissue irritant and must not be extruded beyond the apex [, Sodium hypochlorite accident in a pediatric patient. From: Principles and Practice of Laser Dentistry (Second Edition), 2016, Dennis J. McTigue, ... Janice G. Jackson, in Pediatric Dentistry (Sixth Edition), 2019. An x-ray film may be necessary to allow the success in filling the canals to be evaluated (Fig. A post obturation radiograph is … The materials used for obturation in this study included zinc oxide propolis (ZOP) as a new paste, Endoflas, Metapex, and zinc oxide eugenol (ZOE). These findings explain the complications often encountered in root canal therapy. As aqueous vehicles favor a high degree of solubility, they will cause a depletion of the paste from the root canals, In vitro studies found that Metapex demonstrated minimal inhibition of 23 strains of bacteria isolated from infected root canals of primary molars and three nonstandard bacterial strains using agar diffusion assay [, Maisto’s paste, introduced in 1967, includes both zinc oxide and iodoform, with parachlorophenol camphor, lanolin, and thymol. BACKGROUND: The pulpectomy is an underutilized treatment modality for severely infected primary teeth. found that root resorption of primary molars is accelerated following pulpectomy with iodoform filling material in comparison with teeth without endodontic treatment . Cost: Cost of this procedure plus the crown (cap) (p. 146) required for strength may equal or exceed the cost of tooth removal and placement of a space maintainer. In addition, the rubber dam helps prevent the swallowing or aspiration of foreign objects during treatment. James E. Jones, ... Ghaeth H. Yassen, in McDonald and Avery's Dentistry for the Child and Adolescent (Tenth Edition), 2016. The purpose of the present retrospective study was to assess the success rates of root canal treatment of However, Trope suggests that the pulp contents be removed at the emergency visit and a tetracycline-corticosteroid combination (Ledermix; Sigma Pharmaceuticals Pty Lid., Croydon, Victoria, Australia) be placed in the root canal.48 He believes that this combination decreases the inflammatory response after replantation to allow for more favorable healing than in those teeth that do not receive the medicament. If bleeding does occur, the canal must be explored, so that all pulpal tissue is removed. ZOE tends to resorb at a slower rate than the roots of the primary teeth [, ZOE extruded beyond the apices set into a hard cement that resists resorption (, The antimicrobial action of calcium hydroxide is associated with its ionic dissociation. The canals are completely filled with ZOE. Paper points are used to dry the canal and check for the presence of blood (Tomson et al., 1979). David T. Brown, Mathew T. Kattadiyil, in McDonald and Avery's Dentistry for the Child and Adolescent (Tenth Edition), 2016. 35.7).25 In addition, long-term CaOH therapy has been shown to weaken the tooth root and increase the likelihood of root fractures.26. An x-ray film may be necessary to allow evaluation of the success in filling the canals (Fig. Diagram illustrates the level at which the canine tooth should be cut in relation to adjacent teeth. In A Consumer's Guide to Dentistry (Second Edition), 2002. It is unwise to maintain untreated infected primary teeth in the mouth. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Root canal paste formulas include an RC-2W mixture consisting of 3% BaS04, 6% Titamicin oxide, 8% bismuth sub-nitrate, 18% bismuth subcarbonate, 6.5% paraformaldehyde, and 62.5% zinc oxide (Tomson et al., 1979), or the commercial product Hypo-Cal (Hellmann Dental Manufacturing, Hewlett, New York), which is calcium hydroxide in a calibrated disposable syringe with a special applicator needle. Only two showed statistically significant different success rates between the test and the control groups. CLINICAL IMPLICATIONS: Vitapex is an excellent filling material for primary tooth pulpectomies. Considerable laboratory and animal research has been reported. 19-14). When hemorrhaging is controlled and the canals remain dry, a thin mix of unreinforced zinc oxide–eugenol paste may be prepared (without setting accelerators), and paper points covered with the material are used to coat the root canal walls. Therefore, an intra-radicu-lar filling material should be non-toxic and easily resorbable. Definition. (A) Preoperative view. The tooth should be restored with full coverage. Other techniques have employed epinephrine flushes or electrocautery to stop the bleeding and dry the root canal. A pulpectomy is similar to a root canal, and is actually typically a part of the root canal process. During the time beyond 1 week that the pulp tissue is allowed to remain, evaluation of the tooth is recommended at weekly intervals until favorable signs of healing without pulpal pathosis are conclusive (vitality tests are unreliable) or until a decision is made to extirpate the pulp. The root canal is then irrigated with sterile saline. This practice helps avoid irreparable damage in the form of root fracture in case the restored tooth is once again subjected to trauma. During instrumentation, these curves increase the chance of perforation of the apical portion of the root or the coronal one-third of the canal into the furcation [. The partial pulpectomy technique, which may be completed in one appointment, involves the removal of the coronal pulp as described for the pulpotomy technique. The criteria for pulpectomy, as well as the technique used remained identical, allowing comparison of the effectiveness of both filling materials. In baboons and macaques, a technique termed submucosal vital root retention, involving the amputation of the crown of the canine tooth below the margin of the gum, has been described (Schofield et al., 1991). The laser technique required less time for completion of the cleaning and shaping procedures when compared with both rotary or hand instrumentation [. Fig. RCT in primary teeth may be completed in one visit. Further condensation may be carried out if required. 13-15). A pulpectomy is defined as a root canal procedure for pulp tissue that is irreversibly infected or necrotic as a result of caries or trauma. Endodontic procedures for the treatment of primary teeth are indicated if the canals are accessible and if there is evidence of essentially normal supporting bone. The primary components of Vitapex are calcium hydroxide and iodoform. This resorption causes the position of the apical foramen to change continually [. Root canal treatment should be initiated 7 to 10 days after replantation. Root canal instrumentation may be facilitated with the judicious use of this mechanical technique, especially in canals that are difficult to negotiate with hand instruments. The primary components of KRI paste are zinc oxide and iodoform. Mineral trioxide aggregate (MTA) has also been used as therapeutic pulp-dressing agent.55. Chawla HS, et al.Evaluation of a mixture of zinc oxide, calcium hydroxide and sodium fluoride as a new root canal filling material for primary teeth. The use of micro-computed tomography has produced some exquisite views of the anatomy of primary molars (Figs. pulpectomy in primary teeth: a 18-months clinical randomized controlled trial Xiaoxian Chen1, Xinggang Liu2* and Jie Zhong1 Abstract Background: To avoid untoward changes when primary teeth are replaced by permanent teeth, resorption of the material used in primary teeth root canal filling should occur at the same rate as root resorption. — Pulpectomy for primary teeth can be carried out in a single visit, if the patient is not complaining of acute symptoms or there is no pus discharge from the canals . Excellent results have been observed in many cases. The variations included lateral branching, connecting fibrils, apical ramifications, and partial fusion of the canals. Pulpotomy is a minimally invasive procedure performed in children on a primary tooth with extensive caries but without evidence of root pathology. The root canals and pulp chamber are filled with special dental materials, and a dental filling … In root canal treatment, the dentist will first perform the pulpectomy procedure in which the entire root canal system is cleaned, shaped, filled, and sealed. Khayat et al. Figure 35.7. Pulpectomy : Definition, Indication and Contra-indication. Pulpotomies refer to the opening of the root canal and the partial removal of the pulpal tissue. The instruments employed to fill the canals depend mainly on the material used. Although variations in techniques and chemicals used are described, the pulpectomy procedure, as outlined by Tomson et al. The tooth should be restored with full coverage. 6). The morphology of the root canals in primary teeth makes endodontic treatment difficult and often impractical. Currently, pulpectomies in primary teeth are commonly completed in a single appointment. The canals should then be dried with sterile paperpoints. A sterile, dry cotton pellet or one dampened with CMCP and blotted on sterile gauze may be sealed in the pulp chamber after debridement and irrigation. showed that all root canals obturated with gutta-percha and root canal sealer using either lateral or vertical condensation were recontaminated in less than 30 days when exposed to saliva. The calcium hydroxide material used to fill the root canal should be replaced every 3 to 6 months until a decision is made to fill the canal with gutta-percha. One of the greatest challenges facing the clinician is the treatment of a nonvital immature permanent tooth with an open apex. Concept and procedures. The success of pulpectomy in primary teeth depends on selecting the ideal root canal filling material. RCT is considered successful if clinically pretreatment clinical signs and symptoms resolve within a few weeks and the tooth is painless, presenting healthy surrounding soft tissues and no increased mobility. By continuing you agree to the use of cookies. Table, A description of various root sealers for primary teeth. Vitapex Hibbard and Ireland studied the primary root canal morphology by removing the pulp from extracted teeth, forcing acrylic resin into the pulp canals, and dissolving the covering of tooth structure in 10% nitric acid.19 It was apparent that, initially, only one root canal was present in each of the mandibular and maxillary molar roots. It is particularly important that the teeth in the mouths of accident-prone adolescents or in whom athletic trauma has previously occurred be restored without a post, if possible. It is the technique to gain an access to the root canals, remove as much dead & infected material as possible & fill the root canals with a suitable material to maintain the tooth in a non – infected state. Disadvantages: The cost for this procedure, followed by the crown (cap) (p. 146), which is necessary for strength, is moderate. Mechanical removal of remnants from the canal is performed using a series of 21 mm long K-type endodontic files (Unitek Corp., Monrovia, CA) up to file No. ... this is a common result of this procedure and is due to the staining of the filling materials and the cement used. preferred root canal filling material. Excellent results have been observed in many cases. Leonardo MR, Leal JM, Simões Filho AP. It is challenging to select the appropriate filling materials for primary teeth. The objective of both pulpectomy and pulpotomy is to maintain a tooth both functionally and painlessly without pathology until the primary tooth normally exfoliates upon eruption of the underlying permanent tooth, or until the tooth is adequately developed for definitive root canal therapy. The aqueous, viscous, or oily vehicle used in the formulation of the root canal filling paste impacts the speed of ionic dissociation. Advantages: The tooth is maintained in service. Cautious manipulation is important, however, to prevent breaking the file or overinstrumentation of the canal and apical tissues. If the tooth has painful necrosis with purulence in the canals, however, completing the pulpectomy procedure over two or three visits should improve the likelihood of success. The presence of zinc oxide slows it resorption, and it was reported to have significantly higher success rates (100 %) compared to ZOE alone [, KRI paste (Pharmachemie, Zurich) is a mixture of iodoform (80.8 %), camphor, parachlorophenol, and menthol [, Dental operating microscopes, electronic apex locators, rotary nickel-titanium files and irrigation techniques are at the front of endodontic armamentarium today [, When considering the use of electronic apex locators, only few studies exist and most of them are either in vitro [, As for rotary instrumentation techniques in primary molars, in vitro studies found equal cleaning capacity but reduction of instrumentation time by the rotary technique [, Er,Cr:YSGG laser provided similar cleanliness as rotary instrumentation technique and was superior to manual instrumentation. A pulpectomy is complete removal of pulp from the crown and roots. If the second primary molar is lost before the eruption of the first permanent molar, the dentist is confronted with the difficult problem of preventing the first permanent molar from drifting mesially during its eruption. Zinc oxide eugenol or zinc oxide eugenol/iodoform combined with Ca(OH) 2 appears to be the materials of choice if primary teeth are not nearing exfoliation. Steps in pulpectomy. However, Moskovitz et al. Rubber dam isolation is always desirable when pulp therapy is performed. Nedley MP. However, they are a source of infection and should be treated or removed. The excess thin paste may be removed with paper points and Hedström files. Another popular root canal filling material for primary teeth is Vitapex (Dia Dent Group International, Inc., Vancouver, British Columbia, Canada), a product that has received many favorable anecdotal reports about its successful use in infected primary teeth. Andreasen suggested that 2 weeks after replantation is the ideal time to fill the canal with calcium hydroxide. After the pulp tissue has been removed from the canals, a syringe is used to irrigate them with 3% hydrogen peroxide followed by sodium hypochlorite. The pulpectomy completed by obturating with a cream past of ZOE introduced into the canal first using a file. Because posts and cores do not strengthen endodontically treated teeth, their use is indicated only when the remaining coronal tooth structure does not provide adequate retention for definitive restoration. Because replantation should be done as soon as possible after the injury, the dentist should not take time to extirpate the pulp before replantation. • Advantages - it has bactericidal effect. A thick mix of the treatment paste should then be prepared, rolled into a point, and carried into the canal. The excess thin paste may be removed with paperpoints and Hedström files. After the canal has been filled, excess paste is removed, and an amalgam plugger is used to firmly pack the hardening paste into the filled canal. The canal should be filled approximately 2 weeks after the injury. 13-13 and 13-14). It is also indicated when root maturation is complete and the permanent restoration requires a post buildup. Objective To evaluate the success rate of pulpectomy of primary molars using four different root canal filling materials: ZOP as a new paste, Endoflas, Metapex, and ZOE. These procedures have been used in veterinary medicine for treating tooth fractures and pulp infections and for disarming dangerous animals. Multiple visits over a period of 9 to 18 months were required, however, and the outcome was a shortened root with thin walls (Fig. Design: Fifty prototypes were instrumented and randomly divided (n = 10) according to the filling materials (Vitapex ® , ZOE, Calcicur ® , Feapex, and Calen ® -ZO) and obturation technique: lentulo or pressure syringe (n = 5). The radiograph performed before root canal treatment (in this case, of the lower right second primary molar) should demonstrate the pulp chamber and the full length of the canals, The success of endodontic treatment depends on elimination of the infecting bacteria accomplished through adequate root canal debridement (instrumentation), antibacterial irrigations, and antibacterial filling materials [, Root canal treatment in primary teeth is indicated when the radicular pulp exhibits clinical signs of irreversible pulpitis or pulp necrosis, while the roots show minimal or no resorption. Early extirpation of the pulp may help to control the early onset of inflammatory root resorption.54 Filling the root canal with calcium hydroxide also controls and may even arrest external inflammatory root resorption. If the avulsed permanent tooth has immature root formation with an open apex, the chances of pulpal revitalization after replantation improve considerably, especially if replantation occurs within 30 minutes after avulsion. If small endodontic instruments are used without rubber dam protection, they should be secured with a length of dental floss to facilitate retrieval in the unlikely event that they are dropped in the patient’s mouth. The risk-benefit ratio for the patient favors pulpal extirpation. Even though a few reports of revitalization exist, the chances for revitalization are remote at best. Pulpectomy should not be confused with pulpotomy, ... the root canal and the pulp chamber are filled with an inert and non-absorbable material. Although zinc oxide–eugenol paste has been viewed as the traditional root canal filling material for primary teeth, results from multiple studies23-28 suggest that KRI paste (Pharmachemie AG, Zürich, Switzerland) may be preferable. Small amounts of formocresol may be absorbed and distributed throughout the child's body within minutes of its use at the pulpotomy site,56 and parents may express concern about the effect of such medicaments. Many dentists prefer to use root canal instruments placed in a special handpiece for root canal débridement. The root, however, remains fragile and at increased risk of future trauma because no further dentinal wall apposition can occur. It can usually be used even during the pulp extirpation procedure, while several teeth are splinted together. Figure 35.8. 2001;19:107-109. Thick paste such as ZOE is inserted and condensed with root canal pluggers, while thinner pastes like iodoform and calcium hydroxide-based materials are inserted with a spiral lentulo mounted on a slow-speed engine (Fig. Mature first primary molar canals are often so small that they are inaccessible even to the smallest barbed broach. Radiographic lesions present preoperatively should resolve within 6 months, as evidenced by bone deposition and a decrease or disappearance or at least no change in pretreatment radiolucent areas. Vitapex (New Dental Chemical Products Co. Ltd., Tokyo, Japan)/ Diapex: 30 % calcium hydroxide, 40.4 % iodoform, and 22.4 % silicone oil. A partial pulpectomy may be performed on primary teeth when coronal pulp tissue and the tissue entering the pulp canals are vital but show clinical evidence of hyperemia (Fig. Subsequently, when root formation is completed, a pulpectomy is performed, followed by placement of the definitive restoration or crown, if needed. Six clinical trials selected for inclusion were independently reviewed by two researchers. When hemorrhage is controlled and the canals remain dry, a thin mix of filling paste may be prepared. During a pulpectomy, the dentist will remove the entire pulp tissue so they can clean the crown and roots of the tooth and then fill it with a therapeutic filling material. Restorations that do not use a post should be used whenever possible to replace missing tooth structure and serve as a retentive foundation. Dean, in McDonald and Avery's Dentistry for the Child and Adolescent (Tenth Edition), 2016. difficult to avoid the extrusion of filling materials beyond the root canals in all pulpectomy cases. Many dentists prefer to use root canal instruments placed in a special rotary handpiece and nickel titanium files for root canal debridement. The optimum duration of the calcium hydroxide treatment is unknown, but generally calcium hydroxide should be kept in the canal for at least 6 months or until root end closure (apical plug) occurs beyond 1 year. A mixture of calcium hydroxide and zinc oxide as a root canal filling material for primary teeth: a preliminary study. Root canal instrumentation may be facilitated with the judicious use of this mechanical technique, especially in canals that are difficult to negotiate with hand instruments. Vitapex may be at least as effective as KRI paste, and Nurko and García-Godoy26,29 have published some reports of studies in humans. VARIOUS ROOT CANAL OBTURATING MATERIALS FOR PRIMARY TEETH Most commonly used materials for primary root canal fillings are Iodoform based pastes Walcoff paste KRI paste Maisto paste Vitapex/metapex Endoflas Zinc oxide … Zinc oxide eugenol and aloe vera. A temporary filling material is applied between the visits. About The … Jeffrey A. Pulpectomy: immediate root canal filling with calcium hydroxide. Pulpectomy The procedure requires the removal of all tissue within the pulpal area, as well as in the root canals. The canals should then be dried with sterile paper points. From the clinical aspect the endodontic treatment is divided into two groups: (1) teeth with pulp vitality (biopulpectomy) and (2) pulpless teeth (necropulpectomy). Though overall treatment time is greatly reduced, the shortened root and thin walls continue to place the tooth at risk for subsequent cervical root fracture. from Columbia South America): tri-iodmethane and iodine dibutilorthocresol (40.6 %), zinc oxide (56.5 %), calcium hydroxide (1.07 %), and barium sulfate (1.63 %) with a liquid consisting of eugenol and paramonochlorophenol, Without setting accelerators may be pushed into the root canals using a suitable root canal plugger, Introduced into the root canal using disposable tips or a spiral lentulo mounted on a slow-speed handpiece, Introduced into the root canal using a spiral lentulo. When the canal is filled, calcium hydroxide paste is the material of choice. Of cookies check for the development of the treatment should permit resorption of the pulp tissue removal from the should.
