Only dentist at quality inspection can detect a similar problem. Subgingival forms below the gumline in the sulcus (crevice) between the teeth and the gumline. Is this different for each patient depending on how quickly they build up? Detecting subgingival calculus deposits is key to ensuring periodontal health. While your dentist and dental hygienist can typically detect supragingival calculus visually, dental professionals also receive extensive training using equipment other than their eyes. Background: Previous in vitro studies have proven laser fluorescence measurement using a 655-nm Indium Gallium Arsenide Phosphide (InGaAsP) based diode laser radiation to be a useful tool to detect subgingival calculus. Removing subgingival calculus from the facial surfaces of the maxillary anteriors poses unique problems and requires predictable solutions. More severe periodontal conditions will have better tissue retraction due to looser tissue and this will allow a wider field of view. 2016;31:1621-1626. It will detect subgingival calculus as small as 0.1 mm in size, including tiny spicules, black ledges, and white sheet or veneer calculus. By Donna Smith, BSDH, MSEd, RDHAP On Feb 7, 2020 S uccessful dental hygienists rely on their ability to detect and remove calculus deposits through the use of tactile sensitivity. 2 methods. 2003;18:32-35. It permits operators to detect the presence and location of subgingival deposits and guides them in the thorough removal of these deposits. Fabrication of a michigan splint. 1998;44:1293-1300. Dry the tooth: A wet tooth will cause scattering of the light due to the optical properties of the water. Subgingival calculus detection with fluorescence induced by 655 nm InGaAsP diode laser radiation. All laser fluorescence measurements were made before periodontal surgery. Hence, the 655 nm diode laser may be used as an additional tool for calculus detection in non-surgical periodontal therapy. If recession is slower than attachment loss which is almost always the case then the rate of attachment loss will increase at an increasing rate. With the Calculus Detection PRO, students use an 11/12 explorer to compare and contrast various textures that simulate.... Cementum - hard with a very slight texture Lasers Med Sci. Once all of the plaque is gone, it is easier to detect calculus. that may be felt when using a dental explorer. Please leave a comment and let me know what you think or if there are any topics you would like covered in the future. Because if provides best tactile feeling What is the composition of dental calculus? 2017 Oct;29(4):171-178. doi: 10.1016/j.sdentj.2017.08.001. Compared with image evaluation the laser assessment showed a sensitivity of 0.70 (CI0 .025 0.53 to CI0.975 0.83) and a specificity of 0.97 (CI0.025 0.85 to CI0.975 0.99). Some humble tips for the learning dentist. Subgingival calculus on X-rays. Feels like large protuberance jutting out of tooth surface. The aim of this prospective study was to evaluate the 655-nm InGaAsP diode laser in detecting subgingival calculus in patients with periodontal disease compared with photographic … 2002 Jun;73(6):597-601. doi: 10.1902/jop.2002.73.6.597. Sometimes I find a ledge of calculus on the subgingival facials of 6-11 and 22-27. ODU explorer 11/12. Pad B – Cementum – hard surface with a very slight texture. Feels like distinct bump. It's yellow or tan and is visible on a tooth's surface. A total of 115 tooth surface sites of 32 teeth from the 12 patients were evaluated before (laser) and during surgery (image). CONCLUSION: The autofluorescence method employing excitation of 633-635 nm was found to be a powerful tool for detecting subgingival calculus and root caries. Check these sites carefully with the above methods. Interexaminer and intraexaminer reproducibility in clinically detecting subgingival calculus was also determined. Subgingival calculus is often proximally related to supragingival calculus as the same poor oral hygiene practices that have led to one lead to the other. Van der Weijden GA, Timmerman MF. Different aspects of hand and ultrasonic instrumentation methods have been compared (Claffey et al., 2004). Below are some points on how to identify subgingival calculus. - gently blow 3 in 1 air into pocket, allowing direct vision of calculus on root surfaces * only possible in areas such as lower anterior teeth - cross calculus probe can be used to detect subgingival calculus on root surfaces 28 It typically isn't visible with the naked eye unless gum recession has already taken place. 2019 Apr;37(4):197-226. doi: 10.1089/photob.2018.4465. Pad D – Light or grainy calculus – this texture pad also includes two . It is associated with bacterial deposits some of which may be calculus. Ledge. Having multiple methods to detect subgingival calculus is important to ensure that your periodontal cleans are effective and thorough. They are often adjacent to obvious bone loss areas on the radiograph. I find this the most reliable way to check for calculus as it concurrently allows you to clear GCF and blood away from the site. dental calculus; diagnosis; fluorescence; lasers; periodontitis. And if the supragingival stone visually noticeable, then the second option is more insidious due to its hidden location. Historically, dental profession-als have used conventional (manual) explorers to feel the root surfaces for residual calculus when assessing scaling and … Prevention and treatment information (HHS). An audible beep is emitted when subgingival calculus is detected. © 2020 American Academy of Periodontology. There is supragingival and subgingival dental calculus. Intraoperatively a mucoperiostal flap was performed, subgingival calculus was visualized, and photographic images were taken. For clinical use, it would be important to remove subgingival plaque and debris from root surfaces before attempting to detect subgingival calculus and root caries with this manner. In this case, out of sight doesn't mean out of mind as it is our responsibility to locate these deposits and clean the tooth surface during the patient's regular periodontal maintenance visit. The autofluorescence method employing excitation of 633-635 nm was found to be a powerful tool for detecting subgingival calculus and root caries. Radiographs: Bite wings, periapicals and opgs can identify the extent of calculus formation. Pihlstrom B. due to the papillary fill of the interdental space in virgin teeth any calculus present interproxmially will be by default subgingival calculus. This site needs JavaScript to work properly. The overall probability to correctly detect subgingival calculus with the laser (accuracy) was 0.82 (CI0.025 0.74 to CI0.975 0.88).
