calcium hydroxide extended beyond the apex management

Hydraulic cements refer to a material that needs hydration to set and once set are impervious to dissolution in water. White File Diameter. most endodontists will use calcium hydroxide as an intracanal medicament.63 Care should be taken not to push necrotic debris beyond the apex during root canal instrumentation, as this has been shown to promote more posttreatment discom-fort.13,31,87,96 Crown-down instrumentation techniques have A 48-year-old female presented with persistent occlusal pain. Blackwell Munksgaard, USA, pp. A high degree of success has been reported by using calcium hydroxide beyond the apex in cases with large periapical lesions (21). Hydroxyl ions can penetrate biofilms, inhibit the inflammatory actions of endotoxins and help to dissolve organic tissues [ 1, 2, 3 ]. Cvek reported that radiographic healing and hard tissue formation at the apex of the tooth was noted in 90% of the cases (14). Kerekes K, Heide S, Jacobson I. Apexification with MTA can be performed as a one- or two-visit procedure, eliminating the need for extended periods of dressing with calcium hydroxide. . The AC is mostly located either in dentin or at the CDJ level and less frequently in cementum. A combination of both external and internal resorptions can also occur on the same tooth, making the management more complex. Textbook and color Atlas of traumatic injuries to teeth. The solubility of calcium hydroxide in water is low, being only 0.159 g/100 mL (0.16% by weight) at 25 C. Calcium hydroxide medicament pastes are used widely in endodontics because hydroxyl ion release exerts broad spectrum antimicrobial activity against most pathogens found in the root canal. Summary A total of 42 mature anterior teeth with large periapical lesions ranging in size from 7 to 18 mm in diameter were included in this study. In any formulation, calcium hydroxide can be very alkaline. used calcium hydroxide in teeth with dens tracts for apexification (19,20). 3. 14 months later, the patient returned for treatment of #14. Bleeding must stop. Pure calcium hydroxide paste has a high pH (approximately 12.5-12.8) and is classified as a strong base, which prevents the growth and survival of bacteria. Place rubber dam - this is mandatory for all root canal treatment. 15-45-90. A significant amount was extruded past the apex in close approximation to the maxillary sinuses during the endodontic treatment. Calcium hydroxide has been included within several materials and antimicrobial formulations that are used in a number of treatment modalities in endodontics including intra-canal medicaments. . 2. TempCanal Enhanced is simple to use. (1) use of an anesthetic without a vasoconstrictor when trying to induce bleeding (2) collagen matrix for the controlled placement of mta to a desired and optimal level, with only light pressure placed on the mta during packing (3) patients should be informed about the potential for staining, especially in anterior teeth when the paste contains . All treated patients had favorable clinical and radiographic outcomes. After 7 days, the patient was recalled. Pathways of the pulp (9th ed): 872 2. Calcium hydroxide has been commonly used as an intracanal dressing to induce hard tissue deposition in necrotic teeth with open apices. No swelling was observed. Figure 2: Postsurgical radiographic evaluation for the period of 39 months (a) Preoperative, extruded mass of non-setting calcium hydroxide remained in bone for 2 years (b) Just after surgery, periextrusion thin radiopaque line is visible (c) After 2 months of surgery, healing of bone can be appreciated (d) After 8 months of the tooth resorption by using mineral trioxide aggregate or Calcium hydroxide, calcium apatite have been well . Non Surgical Management of Periapica l Lesion Using Calcium Hydroxide. Apexification done with calcium hydroxide encounters certain difficulties like very long treatment time, possibility of tooth fracture and incomplete calcification of the bridge. Markose A Management of separated instruments from the root canal: A . Ferguson et al. Gray File Diameter. The placement of calcium hydroxide has been shown to promote root end closure as well as have an antimicrobial effect (12,13). After 15 days, the sinus tract disappeared, and the calcium hydroxide was removed, bleeding was stimulated from the apex, and it was finally restored with MTA and final restoration. Release calcium ion which important for cell attachment and proliferation 3. 598-654. Hydraulic calcium silicate-based cements (HCSC) overcome the problem of mechanical instability, at the same time they offer excellent biological properties. 775 Highly Influential PDF View 6 excerpts, references background Resorbable collagen GTR membrane was used to cover the bony crypt. Even the newer bioceramic sealers contain calcium hydroxide in their unset states. Nearly seventy years later Pulpdent continues to lead the way with its newest calcium hydroxide product offering: TempCanal Enhanced. The aim of this paper is to present a case involving. Methods: This case report describes the patient with extrusion of Ca (OH)2 into the periapical tissue in the mandibular right second premolar. and constant consistency mix for an extended period of time. TempCanal Enhanced is simple to use. Calcium hydroxide medication was used in all but 1 case. It also allows for immediate restoration, which further reduces the potential of catastrophic, vertical, or oblique root fractures of such teeth [ 5 ]. Calcium hydroxide is an effective biocompatible substance that has been widely studied in scientific research, and is regarded as the material of choice for treating intracanal infections. Calcium hydroxide was placed for 2 weeks within the root canal as an intracanal medicament. Assessment of Post-Operative Pain with Different Calcium Hydroxide Formulations Used as Intracanal Medicament in RCT 1 Renu Aggarwal, 2 ajnish Aggarwal, . Fava (1993) as well as Marais and Van der Vyver (1996) reported cases of calcium hydroxide extrusion into the maxillary sinus, causing acute pain and a . calcium hydroxide, was most commonly advocated therapy for immature teeth with nonvital pulp. 2 The time needed to form an apical barrier is unpredictable and depends on the size of the apical foramen, the presence of infection and the host. Calcium hydroxide has been the most commonly used material in endodontics since 1920, with various indications from pulp capping, apexification, apexogenesis, and root canal disinfection. It has been reported that if the initial apical file is greater than file size # 40 (0.40mm) it is more likely to have root canal material extruded beyond the root difficult control in manipulation and poor apical seal. The use of calcium hydroxide as an inter-appointment dressing can have adverse consequences if it is accidentally extruded beyond the apical foramen (Fava, 1993; Marais, Van Der Vyver, 1996). apex teeth with necrotic pulp such as apexification, MTA plug and revascularization. MTA is a medical grade mixture of Portland cement and bismuth oxide. Administer local anaesthesia. 2.7. Practical Implications All these high pH materials, when in contact with the inferior alveolar nerve, can cause a gradual and persistent insult to the IAN leading to a neuropathy. This reduces to 0.140 g/100 mL (0.14% by weight) at 40 C, with an accompanying decrease of 0.033 pH unit/C with increasing temperature [ 31 ]. Hence calcium hydroxide was intentionally extruded beyond the Perforation Management. 1-year application of intracanal calcium hydroxide. The literature on biocompatibility of calcium hydroxide especially when extruded into the periapical region is ambiguous with some reports endorsing its tolerance. Calcium hydroxide is classified as a strong base (pH value around 12.5) and dissociated into calcium and hydroxyl ions in contact with aqueous fluids (Ba-hattab et al . Mineral trioxide aggregate View via Publisher msjonline.org Save to Library Create Alert . The remaining treated vital pulp will continue to produce dentine. Open apex & its Management 1. z DR.SSO 2. z OPEN APEX & MANAGEMENT Prepared by, Dr.Sachin Sunny Otta DR.SSO 3. z CONTENTS INTRODUCTION DEFINITION STAGES OF TOOTH DEVELOPMENT CAUSES OF OPEN APEX COMPLICATIONS OF OPEN APEX DIAGNOSIS & CASE ASSESSMENT TREATMENT OPTIONS APEXOGENESIS Indications Contraindications Goals Materials Procedure Follow up Controversies APEXIFICATION Indications . It has osteoco nductive and osteostimulative properties. Therefore, we placed calcium hydroxide and iodoform paste (Metapex) as an intracanal medicament for a relatively long period of time. Purple File Diameter. Apexification with calcium hydroxide has been shown to encourage cementogenesis and osteogenesis (17,18). Andreasen L (2007) Endodontic management and use of calcium hydroxide in traumatized permanent teeth. After removing the temporary filling, the calcium hydroxide dressing was removed from the canals of both the teeth and the canals were thoroughly irrigated. In this article, we present reports of the non-surgical endodontic treatment of two maxillary lateral incisors that had Oehlers type II DI and open apexes, treatment involving the use of collagen membrane and . Abstract - This case report describes the management of a latereferral case of periapically involved, traumatized immature permanent incisors by endodontic treatment and the use of mineral trioxide aggregate (MTA) apical plugs. Upon entry, necrotic tissue was debrided from the canal with a spoon excavator, irrigated with sodium hypochlorite, and filled with calcium hydroxide. Vital Pulpotomy is the treatment of choice when treating healthy, freshly exposed pulp in immature animals where the root apex is still open and the dentine wall is thin. MTA which consist of mainly calcium and silicate, works on several mechanisms: 1. A space was left for immediate placement of fiber post core then crown. 2 it can, however, be more progressive and potentially destructive. 6 |Issue 8 | August 2018 In a subsequent appointment, an amnion membrane was placed at the root apex to serve as an internal matrix followed by a 5 mm apical plug with Biodentine. and Schindler et al. Yellow File Diameter. A 10yearold boy was referred to the clinic with a chief complaint of pain in his maxillary central incisors, which had experienced subluxation trauma 2 years . It was extended 2-3mm . Dey S, Singhania H, Kohli V. Non Surgical management of periapical lesion using calcium hydroxide: A . [8] It can be classified into five categories based on its clinical and histological manifestations. Calcium hydroxide and calcium triphosphate are other materials that can be used as a barrier against which to condense another material. When calcium hydroxide is used as a direct pulp cap over a small exposure of healthy pulp tissue it can stimulate the deposition of a dentine barrier. (22,23) Placement of the root canal paste beyond the apex is not indicated according to contemporary endodontic principles. Calcium hydroxide has been widely used in endodontic treatment as an intracanal medication or an agent for vital pulp therapy due to its antibacterial effect and biocompatibility. Pure calcium hydroxide paste has a high pH (approximately 12.5-12.8) and is classified chemically as a strong base. (intermibent ) A 38-year-old pa.ent presented for root canal treatment Of tooth #25, at the end of the first visit, calcium hydroxide was placed. Prepare an access cavity through the palatal or lingual surface of the crown. Calcium hydroxide pastes used in endodontics. [25, 26, 27] and some rejecting it [28, 29]. canals beyond the apex 3-7. hypochlorite for irrigation. The endotoxins released by the persistent endodontic . Technique (apexification) 1. The extended duration of intracanal dressing might have contributed to faster healing. Calcium hydroxide was the most preferred material for the management of root perforations. Patient pain was unbearable and needed strong acting pain medication. Single-step apexi cation procedures using mineral trioxide aggregate (MTA) have been reported as favorable treatment options for teeth with an open apex, posing greater bene ts compared to the other available medicaments. The authors suggest that the intentional pushing of calcium hydroxide beyond the apex might have been the cause for . Chemically, it is classified as a strong base in contact with aqueous fluids (its pH is about 12.5 - 12.8), and dissociate into calcium and hy- droxyl ions [4]. Calcium hydroxide antibacterial activity is mainly due to the release of hydroxyl ions. Enter the email address you signed up with and we'll email you a reset link. The formation of this apical hard tissue barrier is stimulated by using long-term intra-canal calcium hydroxide dressings ( apexification ). A periapical radiogram was taken and showed calcium hydroxide extended beyond the apex. Besides, a chronic periapical pathosis, as depicted from 2)Diffusability is limited, thus reducing the apical extension of the material 3)Excellent antimicrobial property 4)Less dystrophic calcification 5)Produces initial zone of fixation that does not proceed apically Its main actions are achieved through the ionic dissociation of Ca 2+ and OH ions and their effect on vital tissues, the induction of hard-tissue deposition and the antibacterial properties. Gutta-percha, the most commonly used root filling material, can also act as a periradicular tissue irritant, if it extends beyond the apical foramen (2,3). REFERENCES 1. The resorption process was stopped, re- calcification was extended to the area beyond the root apex. calcium hydroxide, zinc oxide-eugenol, and glass ionomers. Nearly 70 years later, Pulpdent has launched its newest calcium hydroxide paste, TempCanal Enhanced. This long-term calcium hydroxide apexification technique has been shown to be very successful. Patient had severe pain at.me of placement. With a pH greater than 12, TempCanal Enhanced disinfects canals and prevents flare-ups, making it ideal for routine use between visits and for extended treatment of complicated cases. With pH > 12, TempCanal Enhanced disinfects canals and prevents flare-ups, making it ideal for routine use between visits and for extended treatment of complicated cases. Aim To evaluate clinically and radiographically the longterm clinical outcome of nonsurgical root canal treatment using calcium hydroxide in teeth with large cystlike periapical lesions. to determine whether the inflammatory process has extended into the periapical tissues. system. Large periapical lesions can be associated with such teeth. The root canal and invagination were often filled using thermoplasticized gutta-percha techniques, sometimes using an apical plug with a bioceramic material in teeth with large apical openings. This case shows that extrusion of calcium hydroxide [Ca (OH)2] intracanal medicament caused the persistent percussion pain. calcium sulfate, calcium phosphate, bioactive glass.It completely resorbs and regenerates bone in the defect and demonstrates excellent bonding to both bone and soft tissues. The results indicate that the fracture strength of calcium hydroxide-filled immature teeth will be halved in about a year due to the root filling, which may explain the frequent reported fractures of immature teeth filled with calcium Hydroxide for extended periods. Accordingly, the endodontic Pandey V et al. Fluid samples from the lesions contained cholesterol . analyzing the pH and the concentration of calcium ions within the periapical area concluded that a minimum of 2 weeks are necessary for calcium hydroxide bactericidal activity. Indications: - indirect capping for the treatment of caries profunda - direct capping when the pulp is opened or a pulpotomy is performed - lining of cavities to prevent exposure to acid media when using cements Abstract and Figures Premixed non-setting calcium hydroxide (CaOH (2)) paste in pressure syringe system is commonly used in root canal therapy. 1)Forms strong intra- and intermolecular protein bonds leading to superior fixation by cross linkage. However, it may be accidentally extruded during filling procedures. Closing the apex and thickening the dentine wall. However, controlled apical placement of MTA is a challenging procedure to perform using orthograde approach. A range of products has been formulated with different therapeutic actions, the effects of which are partially dependent upon the tissue to which they are applied. 4-5. Calcium hydroxide (Ultracal - Ultradent - 35% Ca (OH)2 with barium sulfate) was used during treatment of this tooth to control exudate prior to obturation. (E) Final partial root filling. management of tooth and associated bone resorption . 52.A 38-year-old pa.ent presented for root canal treatment Of tooth #25, at the end of the rst visit, calcium hydroxide was placed. 10. Because the root structure in those teeth had already been compromised (7, 8), care was given not to cause additional weakening. [3] Whilst the advantages of calcium hydroxide lie in the fact that it has been widely studied and has shown success, the disadvantages are its prolonged treatment time, the need for multiple visits and radiographs. In the present case, calcium hydroxide dressing had possibly been inside the root canal(s) for more than 1.5 years. Thus, calcium hydroxide is highly dependent on the protection of a good-quality restoration to prevent bacterial invasion of the pulp (Bakland 2009 ). Hosoya et al. Various studies using MTA for apexification have shown promising results. Cohen S, Hargreaves KM. The distance between the AC and the AF ranged between 0.4-1.2 mm, while its reported location in relation to the root apex ranged between 0.5-1.01 mm [Table 1]. The alkaline pH provides antibacterial environment 2. Direct pulp capping technique. The intraoral periapical X ray revealed the presence of a separated long file that extended beyond the apex . 46 Journal of Advanced Medical and Dental Sciences Research |Vol. The creation of hard tissue barrier using . Furthermore, it has been demonstrated that placement of calcium hydroxide and iodoform paste (Metapex) for treatment of an avulsed permanent tooth led to continued root-end growth and successful apexification . (F) 1-year follow-up . calcium hydroxide or the placement of calcium hydroxide into the periapical cyst is considered an alternative to over-instrumentation. Calcium hydroxide is used and supplied in various forms. [4] Endodontics For more than 70 years calcium hydroxide has played a major role in endodontic therapy, although many of its functions are now being taken over by the recently introduced material MTA. Calcium hydroxide has a high pH, and its dental use relates chiefly to its ability to stimulate mineralization, and also to its antibacterial properties [8]. Arrest bleeding with gentle pressure from a sterile pledget of cotton wool moistened with saline (0.9%) placed over the exposure for 1-2 minutes. An endodontic image should show ___ to ___ mm beyond the apex. D. Risk of extending materials beyond apex. the process can be self limiting and is often sub-clinical as seen in the case of surface resorption. [2,3] (4 th edn), Ames, Lowa. Apexification is the treatment of choice for necrotic teeth with immature apex. 08. Follow-up . Access opening was initiated followed by thorough cleaning and shaping of the root canals. The first-generation bioceramic or hydraulic cement introduced in endodontics is mineral trioxide aggregate (MTA) in the 1990s by Dr. M. Torabinejad. One-step apexification using mineral trioxide aggregate (MTA) has been reported as an alternative treatment modality with more benefits than the use of long-term calcium hydroxide for teeth with. Calcium hydroxide is a white odourless powder with the chemical formula Ca(OH) 2 and a molecular weight of 7.08. Evidently, the use of non-setting calcium hydroxide loaded with syringe under positive pressure was what happened in this case. Induces differentiation and migration of osteoblast 4. There is clinical evidence that as the periapical lesion increase in size, the incidence of radicular cysts increases. Which of the following would be the most appropriate management? Calcium hydroxide dressing was placed for 7 days (Iodotin, Techno Dent) in both 21 and 22. The exact mechanism . contact between the calcium hydroxide and the periapical tissues is beneficial for the Osseo-inductive property of the material (19,20). fracture occurs near the apex in the early stages of endodontic treatment, particularly in the presence of a peri-apical pathology.9-11 In this report, the fractured instrument was not only near the apex, but it extended beyond the apex into the medullary bone. [4] In The advantage of MTA apexification are: (i) Reduction in treatment time (ii) possibility to restore the tooth with a minimal delay (iii) no changes in the mechanical properties of dentine (iv) excellent biocompatibility and (v) stimulation of repair. Calcium hydroxide packed into the root canal after the successful removal of the fractured instrument. Mineral trioxyde aggregate versus calcium hydroxide in apexification of non vital immature teeth: Study protocol for a randomized controlled trial By R. Serreau and B. Baune MM-MTA for a Complete Endodontic Obturation of an Avulsed Immature Permanent Incisor: A Case Report Calcicur is a radiopaque, ready-to-use water-based calcium hydroxide paste with a pH value of >12.5. The nonsurgical management of teeth with necrotic pulps and incomplete apex formation with MTA is a useful treat-ment option, with many of the advantages when compared with the traditional calcium hydroxide apexification. Calcium hydroxide has long been used as an intracanal medicament to slow down the resorption process due to its alkaline pH. 2 the resorptive process. 4 The. This case reported to emergency clinics at King Khalid University, College of Dentistry (KKUCOD) after an accident of overextrusion of calcium hydroxide (Ca (OH) 2) from tooth # 22 extended distally to greater palatine foramen area without sinus communication. (16 mm 10 mm, 6 mm 9 mm). although the exact mechanism of action of calcium hydroxide is still speculative, it is obvious that its use beyond the apex has resulted in the successful nonsur- gical management of many cases of large periapical lesions.10,31-34 ~ah~kan and ~en34 suggested that teeth with periapical lesions in which calcium hydroxide paste was extruded did not Pa.ent had severe pain at.me of placement.Periapical radiogram was taken, and showed calcium hydroxide extended beyond the apex. 2 weeks within the root canal ( S ) for more than 1.5 years for 7 days ( Iodotin Techno The pulp ( 9th ed ): 872 2 and once set are impervious to dissolution in water th )!
