direct contact with the bacteria to be lethal. This should be taken into consideration when treating visible teeth. After root canals were prepared and enlarged to a minimum of size 30 with the Profile 0.06 system, calcium hydroxide paste was placed in the canals of two groups, but no medication was placed in the control group. It is concluded that Candida is not uniformly distributed throughout the mouth but that the tongue is the primary oral reservoir for the fungus, from which the rest of the oral mucosa, plaque-coated surfaces of the teeth and the saliva may become secondarily colonized in a proportion of carriers. and OH- ionic, 2. it is not used as a root filling material. The apical extent of the root canal system of primary teeth is difficult to determine (Goerig & Camp 1983, Rimondini & Baroni 1995). 18 This is probably due to an inflammatory response present in the radicular pulp. The intracanal calcium hydroxide was removed with two different techniques, 1 week after medication: K-files one size larger than the master apical file (MAF) were used with 2.5% NaOCl and 15% EDTA solutions in one group, whilst K-files the same size as the MAF were used with 2.5% NaOCl solution in another group. These data provide a rational explanation for the action of Ca(OH)(2) during pulp capping in which the cellular activities involved in dentine bridge formation may be mediated through release of growth factors and other bio-active molecules from the dentine by Ca(OH)(2). the following mechanisms (Siqueira & Lopes 1999): • damage to the bacterial cytoplasmic membrane; When used as a pulp-capping agent and in apexification, cases, a calcified barrier may be induced by calcium, hydroxide (Eda 1961). And so the calcium hydroxide dental is in such demand among people. Although calcium hydroxide is not very soluble in water, a suspension of the finely divided powder in water can be made, a … All rights reserved. Oil-based vehicles such as olive oil, silicone oil, camphor (the oil of camphorated parachlorophe, nol), some fatty acids (including oleic, linoleic, and, isostearic acids), eugenol and metacresylacetate, Staehle et al. Allow slow diffusion in the tissues with low, 3. The success rate for the treatment was 75.5 percent after one year and at least 61.9 percent after two years. (1982) stated that a paste prepared with, water or other hydrosoluble non-viscous vehicle does, not have good physicochemical properties, because it is, not radio-opaque, is permeable to tissue fluids and is, rendered soluble and resorbed from the periapical area, and from within the root canal. Demineralized dentin ground sections showed increase in light zones after total period of storage. Calcium hydroxide provides the high pH (>10) environment that, along with iodoform, has a high bacteriostatic effect . In the permanent dentition it would inappropriate using Ca-OH as a root filling material. 46-48. Canals were obturated with gutta-percha and Tubli-Seal cement using the lateral condensation technique. Not to alter the excellent biological properties of, Calcium hydroxide paste for use in endodontics is. A, radiopacifier should have an atomic weight higher than. Variables in the pulpotomy procedure were recognized and controlled in an attempt to obtain a more favorable result or end product. Introduction: Calcium hydroxide (CaH) is customarily used for permanent teeth but not for deciduous dentition because it is known to cause internal resorption in the latter. Inspite of its desirable properties yet Calcium hydroxide is resorbable which does make it a long term good sealer . The coronal aspects of the root canals were then sealed with zinc oxide-eugenol cement. This is because of its high alkalinity, which changes the acidic pH of periapical tissues to a more basic environment [2] [5] . High pH of Ca(OH)2 causes, irritation of the pulp tissue, which stimulates repair of, dentin by the release of bioactive molecules such as, Bone Morphogenic Protein and Transforming Growth, Dr. Rashmi Baranwal is pursuing her Post Graduation in Pedodontics and Preventive Dentistry. inflamed tissue. This is the main reason radio-, paque materials are added to the paste, thereby allow-. Oper Dent. Periapical Healing of Long Standing Lesion: Glenn. Please suggest the possible solution. The first reports dealing with successful pulpal healing, using calcium hydroxide appeared in the literature, between 1934 and 1941. matrix protein. Artificial demineralized dentin was induced through pH cycling (8 h in demineralizing and 16 h in remineralizing solutions). Effect of calcium, hydroxide form and placement on root dentine, Arendorf TM, Walker DM. The effects of extracts on TGF-beta1, Collagen-1alpha and Nestin gene expression were analysed using semi-quantitative RT-PCR in the dental MDPC-23, OD-21 and fibroblastic Swiss 3T3 cell lines following 24h of exposure. Under aseptic conditions the root canals were filled with a gutta-percha master cone size 70 and Sealapex (48 roots), CRCS (48 roots), and a zinc oxide-eugenol type sealer, Roth 801 (50 roots). International Journal of Dental Sciences and Research, Indian Journal of Forensic Medicine and Toxicology. Therefore, it use as a permanent root filling material is contraindicated. The best results were obtained with CRCS. 2007;52(2):118–121. • Initially bactericidal then bacteriostatic. ... Calcium hydroxide provides the high pH (>10) environment that, along with iodoform, has a high bacteriostatic effect . - Baranwal R (rashmibaranwal@hotmail.com), . Influence of calcium hydroxide, intracanal medication on apical seal. The purpose of this paper is to review the properties and clinical applications of calcium hydroxide in endodontics and dental traumatology including its antibacterial activity, antifungal activity, effect on bacterial biofilms, the synergism between calcium hydroxide and other agents, its effects on the properties of dentine, the diffusion of hydroxyl ions through dentine and its toxicity. However, there was no significant difference between the two calcium hydroxide-medicated groups (P > 0.05). area for longer periods of time (Athanassiadis et al. The effect of calcium hydroxide on, solubilisation of bio-active dentine matrix. both primary or permanent teeth, generally the procedure is considered controversial in case of the use of calcium hydroxide which can cause internal resorption of primary teeth. STUDY DESIGN: A total of 18 primary molars with advanced caries and root resorption of approximately half the root length were randomly placed into 2 groups. 1991 Nov;17(11):541-3. Effect of 2% Chlorhexidine Gel, Mixed with Calcium Hydroxide as an Intracanal, Medication on Sealing Ability of Permanent Root, Canal Filling: A 6-month Follow-up. Frequently asked questions in direct pulp capping of permanent teeth. Table 1. However, there was a significant difference between CH and NEC in comparison with MTAs and PC groups (P < 0.001). In vivo sealing ability of calcium hydroxide-containing root canal sealers. One hundred sixty single-rooted human teeth were used. According to some authors (Maisto, 1975, Goldberg 1982, Leonardo et al. While this material has been the golden standard for many years for a wide variety of pulp and periradicular applications, its usefulness over time is all but nil. Heilig J, Yates J, Siskin M, McKnight J, Turner J. Calcium hydroxide pulpotomies were performed in 17 carious primary mandibular molars. Overall, aqueous calcium hydroxide paste placed in the pulp chamber provided the highest pH values during the experiment, except at day 14. All content in this area was uploaded by Alok Dubey on Nov 03, 2016, Baranwal R*, Singh BD**, Dubey A***, Avinash A****, *PG Student, **Prof.& HOD, ***Reader, ****Sr. • Does not adhere to dentin or resin restoration. Calcium hydroxide is also an effective anti-endotoxin agent. Sleder FS1, Ludlow MO, Bohacek JR. Biomineral, Calcium hydroxide, Intracanal medicament, Weeping canal, 1. This review of the literature provides evidence-based recommendations to guide clinicians in their decision-making process when they encounter a situation requiring pulp capping.
