Unfortunately, these items often go into disrepair and become ineffective or useless. Reasons include a lack of understanding regarding how to set up, maintain, disinfect, sharpen, sterilize, or routinely replace instruments or equipment parts. To continue to work at peak capacity, dental delivery units and their working parts (e.g., air compressors, water and compressed-air lines, handpieces, air\/water syringe, suction, ultrasonic scalers) require care before and after use as well as at other periodic intervals. Instruments that come in contact with a patient\u2019s saliva or other body fluids must be cleaned (to be entirely free of biological materials), disinfected, and, whenever possible, steam autoclaved.<sup>1<\/sup><\/span><\/p>\n<p class=\"p2\"><span class=\"s1\">Staff education on adequately maintaining and using this equipment as well as written and carefully followed protocols are necessary to prevent dental delivery unit, instrument, or equipment breakdowns or failures. Protocols must be established for maintenance and use for each piece of equipment and instrument in the dental armamentarium. In addition, careful organization of all hand instruments into CORE (comprehensive oral and radiology evaluation) dental packs (<\/span><span class=\"s2\"><b>BOX 1<\/b><\/span><span class=\"s1\">) and oral surgery packs (<\/span><span class=\"s2\"><b>BOX\u00a02<\/b><\/span><span class=\"s1\">) helps prevent instrument damage and loss and increases procedural efficiency. CORE is the foundational procedure that involves evaluating oral structures, bone, teeth, and soft tissues through full-mouth dental radiographs and clinical evaluation to probe and chart all pathology found. The CORE dental procedure also involves cleaning, polishing, and irrigating tooth structures above and below the gingival margin.<\/span><\/p>\n<div class=\"su-box su-box-style-default\" id=\"\" style=\"border-color:#606060;border-radius:3px;\"><div class=\"su-box-title\" style=\"background-color:#939393;color:#FFFFFF;border-top-left-radius:1px;border-top-right-radius:1px\">BOX 1 Instruments in a CORE Dental Pack<\/div><div class=\"su-box-content su-u-clearfix su-u-trim\" style=\"border-bottom-left-radius:1px;border-bottom-right-radius:1px\">\n<ul>\n<li>An easy-to-read dental probe\/explorer combination instrument<\/li>\n<li>A dental mirror to reflect image and light and retract or push away the tongue or lips as needed<\/li>\n<li>A hand scaler appropriately sized to the tooth surfaces to be scaled<\/li>\n<li>2\u20133 curettes sized to match the curvature of tooth root surfaces and the interdental area below the gingival margins of the tooth surfaces<\/li>\n<\/ul>\n<p><em>CORE=comprehensive oral and radiology evaluation<\/em><\/div><\/div>\n<div class=\"su-box su-box-style-default\" id=\"\" style=\"border-color:#606060;border-radius:3px;\"><div class=\"su-box-title\" style=\"background-color:#939393;color:#FFFFFF;border-top-left-radius:1px;border-top-right-radius:1px\">BOX 2 Instruments in an Oral Surgical Pack <\/div><div class=\"su-box-content su-u-clearfix su-u-trim\" style=\"border-bottom-left-radius:1px;border-bottom-right-radius:1px\">\n<ul>\n<li>Surgical instruments used to create and close a gingival flap\n<ul>\n<li>Scissors (surgeon\u2019s preference)<\/li>\n<li>Needle holder drivers<\/li>\n<li>Thumb forceps<\/li>\n<li>Periosteal elevator<\/li>\n<li>Suture scissors<\/li>\n<\/ul>\n<\/li>\n<li>Extraction instruments\n<ul>\n<li>Winged elevators (2, 3, 4, or 5 mm)<\/li>\n<li>Luxators of choice<\/li>\n<li>Extraction forceps<\/li>\n<\/ul>\n<\/li>\n<li>Additional instruments\n<ul>\n<li>Lip retractor<\/li>\n<li>Miller curettes (to clean alveolus)<\/li>\n<li>Magnetic bur block<\/li>\n<li>Assortment of friction-grip carbide burs<\/li>\n<li>Diamond burs (medium grit, football shape)<\/li>\n<li>4-0 and 5-0 absorbable suture material<\/div><\/div><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2 class=\"p3\">The Veterinary Dental Operatory<\/h2>\n<p class=\"p2\"><span class=\"s1\">A well-planned room or space used for dental procedures must contain several pieces of large equipment, such as a dental delivery unit, dental table (adjustable height), dental radiology equipment, and anesthesia equipment (<\/span><span class=\"s2\"><b>FIGURE 1<\/b><\/span><span class=\"s1\">).

Be sure that air-inlet ducts are free from hair and debris. <\/span><\/p>\n<p class=\"p2\"><span class=\"s1\">To check the compressor for air leaks, fully pressurize the tank, check the PSI level, and turn the compressor switch off. After 10 minutes with the lines under full pressure, check the PSI gauge; it should not lose more than 10% of ideal pressure. If the system fails pressure testing, air leaking can cause the compressor to engage more frequently, overworking the motor and potentially shortening the motor\u2019s lifespan.<\/span><\/p>\n<p class=\"p2\"><span class=\"s1\">All compressors need to have the air and water discharged out of the tank at least nightly, and the compressor should be turned off and free of compressed air\/moisture in the tank on days when not used.<sup>1<\/sup> Equipment manuals can be found on the manufacturer\u2019s website or at <a href=\"https:\/\/www.manualslib.com\"><span class=\"s3\">manualslib.com<\/span><\/a>.<\/span><\/p>\n<h3 class=\"p4\">Ultrasonic Scalers<\/h3>\n<p class=\"p2\"><span class=\"s1\"><b>Use:<\/b> Ultrasonic scalers use electrical power to convert sound waves into mechanical vibrations, which remove debris from tooth surfaces.<sup>1<\/sup> A liquid (usually distilled water) is required to create the cavitational effect necessary to disrupt the biofilm on tooth surfaces and remove tartar buildup.

If you have a choice, consider environmentally friendly, nontoxic, and nonallergenic products. Never submerge the handpiece in water, chemicals, or an ultrasonic bath. Many autoclaves have a \u201chandpiece\u201d setting for ease of autoclaving high- and low-speed handpieces. Autoclaving a dirty handpiece can \u201cbake\u201d the blood and saliva into the head of the handpiece and the turbine, thereby decreasing the turbine\u2019s lifespan.<sup>5<\/sup> Remove the bur as autoclaving with a bur in place can cause corrosion as a result of the different metals in the bur shank and the turbine.

Know the signs of turbine failure; the turbine should firmly hold the shank of the bur without wobble or expulsion. The bearings in the turbine are susceptible to poorly made dental burs or stress brought on by the use of dull burs. Bearings can fail in the presence of increased heat or pressure, debris buildup, or if the bur is not fully seated into the turbine.

Rotation direction is not critical for polishing; however, the handpiece will not operate with this control in a neutral position. <\/span><\/p>\n<h3 class=\"p4\">Air\/Water Syringe<\/h3>\n<p class=\"p2\"><span class=\"s1\"><b>Use:<\/b> The air\/water syringe is used to irrigate or dry tooth surfaces. To avoid subcutaneous emphysema or air embolism, never project air into an open surgical site. <\/span><\/p>\n<p class=\"p2\"><span class=\"s1\"><b>Maintenance: <\/b>Some water spouts are disposable; for those that are not, remove the spout and clean it thoroughly in an ultrasonic bath. Disinfect or autoclave it.<sup>1<\/sup> To be sure the controls are not getting sluggish or obstructed with prophy paste or other debris, use alcohol on gauze to thoroughly clean under the air and water flow buttons. <\/span><\/p>\n<h3 class=\"p4\">Carbide Dental Burs<\/h3>\n<p class=\"p2\"><span class=\"s1\">Carbide bur shanks come in 2 lengths: 19 mm is standard and 25 mm is considered a surgical length for use when deep reach is necessary. Carbide burs come in different configurations: round (used for bone removal), cross-cut taper fissure (used for sectioning teeth down to single root sections), and specialized (e.g., pear- or cone-shaped) (<\/span><span class=\"s2\"><b>FIGURE 9<\/b><\/span><span class=\"s1\">). Even though tungsten carbide dental burs are 3 times stronger than steel, their cutting edges can become dull quickly when used to drill bone or tooth substances. Therefore, these burs should be used for only 1 procedure and then properly discarded (e.g., into a sharps container).<\/span><\/p>\n<div id=\"attachment_11003\" style=\"width: 460px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig9.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-11003\" class=\" wp-image-11003\" src=\"https:\/\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig9.png\" alt=\"\" width=\"450\" height=\"306\" srcset=\"https:\/\/navc.sitepreview.app\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig9.png 936w, https:\/\/navc.sitepreview.app\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig9-300x204.png 300w, https:\/\/navc.sitepreview.app\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig9-768x523.png 768w\" sizes=\"(max-width: 450px) 100vw, 450px\" \/><\/a><p id=\"caption-attachment-11003\" class=\"wp-caption-text\">Figure 9. Carbide burs (assortment).<\/p><\/div>\n<p class=\"p2\"><span class=\"s1\">If used when dull, the bur shank will apply force to the turbine, significantly shortening the turbine\u2019s lifespan (leading to premature failure) and potentially extending surgical times due to ineffective and worn-out burs (increasing the time needed to section teeth or remove bone). Thus, do not reuse carbide burs; new burs are less expensive than new turbines.<\/span><\/p>\n<h3 class=\"p4\">Diamond Dental Burs<\/h3>\n<p class=\"p2\"><span class=\"s1\">Diamond burs consist of a stainless steel base (head, neck, and shank) with the head bonded over with a diamond powder. The advantage of a diamond bur is that its durable coating can grind away hard tissues, such as enamel and bone. Diamond burs are meant for grinding, not cutting.<\/span><\/p>\n<p class=\"p2\"><span class=\"s1\">In veterinary dentistry, diamond burs are often used to smooth the alveolar crest after a tooth extraction and prevent bony spicules from leaving a rough edge before suturing. Diamond burs are also used for crown preparations when prosthodontic procedures are performed after root canal procedures. <\/span><\/p>\n<h3 class=\"p4\">Water Supply<\/h3>\n<p class=\"p2\"><span class=\"s1\">Follow the manufacturer\u2019s recommendations on decontaminating the water lines and tubing, which may involve bleaching or in-line water filters. Distilled or mineral-free water prevents minerals from clogging or corroding water lines and handpieces. Store the unit as dry as possible when not in use. Drying the water tubing of your dental unit involves depressing the rheostat pedal and blowing the water out of the lines when air pressure is still in the compressor tank. Last, remove the water bottles and dump all the water out; let the bottles dry overnight or over a weekend when not in use.<\/span><\/p>\n<h3 class=\"p4\">Suction<\/h3>\n<p class=\"p2\"><span class=\"s1\">If the unit has a suction attachment and tips, be sure that they are cleaned and disinfected after every procedure, especially the collecting bottles and tubing.<sup>1<\/sup> Disposable suction tips are convenient and help prevent patient-to-patient cross-contamination.<\/span><\/p>\n<h3 class=\"p4\">Additional Cleaning and Maintenance<\/h3>\n<p class=\"p2\"><span class=\"s1\">The outer housing of the dental delivery unit, the rheostat (foot pedal), and the air filters should be checked, cleaned, replaced, and maintained to be clean, free of hair and other debris, and in good working order.<\/span><\/p>\n<p class=\"p2\"><span class=\"s1\">After you have obtained the official instructions for your unit online, write up a simple use and maintenance protocol or log. A log sheet can ensure that the maintenance is done on time and at exact intervals. Train all staff who will be using this equipment on its proper use and maintenance. <\/span><\/p>\n<h2 class=\"p3\">Veterinary Dental Hand Instruments<\/h2>\n<p class=\"p2\"><span class=\"s1\">Hand instruments for veterinary dentistry are essential and complementary to ultrasonic scalers and low- and high-speed handpieces. Hand instruments for dentistry can be divided into 2 main groups: those used for diagnostics and periodontal therapy (which can be placed in a CORE dental pack [<\/span><span class=\"s2\"><b>FIGURE 10<\/b><\/span><span class=\"s1\">]) and those used for oral surgery, extractions, and dental procedures other than cleaning of tooth crowns or root structures (which can be placed in an oral surgery pack [<\/span><span class=\"s2\"><b>FIGURE\u00a011<\/b><\/span><span class=\"s1\">] or other procedure packs).<\/span><\/p>\n<div id=\"attachment_11004\" style=\"width: 459px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig10.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-11004\" class=\" wp-image-11004\" src=\"https:\/\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig10.png\" alt=\"\" width=\"449\" height=\"337\" srcset=\"https:\/\/navc.sitepreview.app\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig10.png 864w, https:\/\/navc.sitepreview.app\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig10-300x225.png 300w, https:\/\/navc.sitepreview.app\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig10-768x576.png 768w\" sizes=\"(max-width: 449px) 100vw, 449px\" \/><\/a><p id=\"caption-attachment-11004\" class=\"wp-caption-text\">Figure 10.

Oral surgery pack.<\/p><\/div>\n<p class=\"p2\"><span class=\"s1\">Dental instruments for procedures such as diagnostics, tooth crown scaling, and subgingival cleaning (including root planing and subgingival curettage) should be cleaned thoroughly, sharpened, inspected, and steam sterilized in packs for use on each patient.<sup>1 <\/sup><\/span><\/p>\n<p class=\"p2\"><span class=\"s1\">Surgical instruments commonly used to perform oral surgery include winged elevators, straight elevators, luxators, periosteal elevators, and a bur block (<\/span><span class=\"s2\"><b>BOX\u00a02<\/b><\/span><span class=\"s1\">). Instruments used to create and close surgical flaps (e.g., blade handle, scissors, needle drivers, thumb forceps) must be selected, sharpened, packaged, sterilized, and kept in good working order between procedures.<\/span><\/p>\n<p class=\"p2\"><span class=\"s1\">The organization of hand instruments is critical for maintaining efficient use, cleaning, sharpening, and sterilization.<sup>1<\/sup> Organization tools that can be easily found include colorful trays, tray holders, instrument marking tape, bands, or colored stick-on dots. To avoid cleaning and autoclaving unused instruments, individually package rarely used instruments and autoclave them separately rather than in the primary dental packs.<\/span><\/p>\n<h2 class=\"p3\">Sharpening Veterinary Dental Instruments<\/h2>\n<p class=\"p2\"><span class=\"s1\">Most handheld instruments for dentistry require a sharp edge to perform the desired task. Instruments such as dental elevators, luxators, periosteal elevators, scissors, hand scalers, and curettes must continually maintain sharp edges. Thus, sharpening dental instruments is essential for their effective and safe use. Instruments become dull with just a few uses, so it is crucial to sharpen them after every use before autoclaving.<sup>7<\/sup> Any dental instruments worn beyond usefulness due to sharpening and use on tooth surfaces should be discarded or recycled.<\/span><\/p>\n<p class=\"p2\"><span class=\"s1\">The goal of instrument sharpening is to restore a sharp edge or edges while maintaining the original design of the instrument.<sup>8<\/sup> Therefore, all dental instruments must be inspected for damage under magnification before and during the sharpening process. In addition, a sharpening test stick should be used to test instrument edges for sharpness.<sup>1,8<\/sup><\/span><\/p>\n<p class=\"p2\"><span class=\"s1\">It is crucial to preserve the original design and shape of the working end of the instrument. Incorrect sharpening techniques can alter the design and weaken the instrument, resulting in an instrument that does not adapt to tooth surfaces correctly and is prone to breaking.<sup>7<\/sup> Instrument sharpening must be learned and practiced, becoming part of the routine process of cleaning and autoclaving hand instruments used for veterinary dentistry. The most helpful way to learn how to sharpen instruments is by taking a class on techniques and practicing under supervision. <\/span><\/p>\n<p class=\"p2\"><span class=\"s1\">To sharpen dental instruments, use a fine-grit stone (e.g., a natural Arkansas stone) with honing oil applied or a synthetic stone (e.g., a ceramic stone) with water applied (<\/span><span class=\"s2\"><b>FIGURE 12<\/b><\/span><span class=\"s1\">).<sup>1<\/sup> Instrument sharpening videos are available at <a href=\"http:\/\/www.pawsitivedental.com\"><span class=\"s3\">pawsitivedental.com<\/span><\/a>.<\/span><\/p>\n<div id=\"attachment_11006\" style=\"width: 459px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig12.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-11006\" class=\" wp-image-11006\" src=\"https:\/\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig12.png\" alt=\"\" width=\"449\" height=\"455\" srcset=\"https:\/\/navc.sitepreview.app\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig12.png 792w, https:\/\/navc.sitepreview.app\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig12-296x300.png 296w, https:\/\/navc.sitepreview.app\/todaysveterinarynurse.com\/wp-content\/uploads\/sites\/3\/2022\/09\/Altier_TVNFall22_DentalInstruments_Fig12-768x778.png 768w\" sizes=\"(max-width: 449px) 100vw, 449px\" \/><\/a><p id=\"caption-attachment-11006\" class=\"wp-caption-text\">Figure 12.
