A sealer acts as a binding agent that fills in these spaces. It binds the materials and prevents leakages.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Lubrication\"><\/span>Lubrication<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Sealers have lubricating properties. Gutta-percha is a solid material and does not flow or lubricate the dentin walls. It helps the solid gutta-percha to penetrate the narrow areas within the canals and facilitate proper placement of the core filling material.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Adhesive_agents\"><\/span>Adhesive agents<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Sealers chemically bond and attach to the core materials and the dentin and prevent micro-leakage of fluids.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Antibacterial_components\"><\/span>Antibacterial components<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Sealers may have antimicrobial properties that remove residual bacteria and microorganisms from the root canal and prevent further infections. This enhances the longevity of the root canal treatment.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Biocompatibility\"><\/span>Biocompatibility<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Root canal sealers are biocompatible which means they bond well with the surrounding tissues and do not cause adverse reactions like allergies, infections, or inflammations.<\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_are_the_types_of_endodontic_sealers\"><\/span>What are the types of endodontic sealers?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A good sealer should provide a tight seal, are non-toxic, and are well-absorbed by the soft tissues present in the root canal.<\/p>\n<p>Ideal properties include:<\/p>\n<ul>\n<li>Opacity (visible on radiographs)<\/li>\n<li>Provides a hermetic or air-tight seal<\/li>\n<li>Allows good chemical binding<\/li>\n<li>Fine powder that mixes well with other solvents<\/li>\n<li>Nontoxic, non-irritating, and non-staining<\/li>\n<li>Tissue-tolerant<\/li>\n<li>Antibacterial<\/li>\n<li>Does not shrink after setting<\/li>\n<\/ul>\n<p>Types of sealers:<\/p>\n<p><strong>Zinc oxide eugenol-based (ZOE) sealers<\/strong> \u2013ZOE is widely used for endodontic and root canal treatments. It is one of the oldest sealers developed in 1931 by Rickert and Dixon, which came to be known as the Kerr sealer. Later in 1936, Grossman developed a formula known as Proco-Sol. ZOE consists of zinc oxide and liquid eugenol, an oil extracted from cloves. Some drawbacks of ZOE are slow setting time, high solubility, and weak in nature.<\/p>\n<p><strong>Calcium hydroxide-based (CH) sealers<\/strong>\u2013It is highly alkaline and is believed to help in remineralisation procedures. It has antimicrobial properties. Studies show that CH has mild cytotoxicity compared to other sealers.<\/p>\n<p><strong>Epoxy resin-based sealer<\/strong> \u2013 Epoxy resin sealers like AH Plus have less solubility and take approximately 8 hours to set. Other epoxy sealers like AH 26 have good flow, high adhesivity, and low solubility but a comparative study shows that it is more toxic compared to AH Plus.<\/p>\n<p><strong>Glass ionomer-based sealer<\/strong>\u2013These sealers have good adhesion qualities and bond well with the dentin. Disadvantages are that they have minimal microbial activity and need to be removed during retreatment.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Final words<\/strong><\/p>\n<p>Dentists should choose endodontic sealers that are leakage-free, offer tight sealing, and protect the root canal and dentin from long-term bacterial infections.<\/p>\n<p>For budding dentists and expert dental professionals, academies like <a href=\"https:\/\/www.aadeindia.com\/\">AADEINDIA<\/a> are providing tailored courses in general dentistry under the guidance of top-notch expert doctors and reputed MDS faculties.
