Extracted teeth with various levels of subgingival deposits of calculus were mounted anatomically in stone casts, and an impression material was used to replicate periodontal soft tissues. The casts were examined for the presence of subgingival calculus at eight surfaces per tooth (240 sites) using LF and a periodontal probe. Sites were rescored after 1 and 3\u2009weeks. Direct imaging of the root surfaces under magnification was the gold standard. As a result, for an experienced operator, LF was more accurate than tactile assessment (across all sites, 84.0% vs. 59.8%). The performance difference was greater for multi\u2010rooted teeth (85.8% vs. 56.9%) than single\u2010rooted teeth (77.2% vs. 66.7%). The performance of LF in this laboratory trial was influenced strongly by clinician skill and experience. When used by an experienced operator, LF was more sensitive (75.1% vs. 69.2%), specific (92.6% vs. 86.3%), and accurate (84% vs. 77.9%) than for an inexperienced operator. In conclusion, under the defined laboratory conditions used, LF had better performance than tactile examination, particularly for multi\u2010rooted teeth. This method may have value clinically as an adjunct for detecting subgingival deposits of calculus in clinical practice. The usefulness of the method improves with operator experience.<\/jats:p>","DOI":"10.1002\/cre2.5","type":"journal-article","created":{"date-parts":[[2015,10,5]],"date-time":"2015-10-05T06:14:44Z","timestamp":1444025684000},"page":"26-31","source":"Crossref","is-referenced-by-count":11,"title":["DIAGNOdent Pen versus tactile sense for detection of subgingival calculus: an in vitro study"],"prefix":"10.1002","volume":"1","author":[{"given":"Fardad","family":"Shakibaie","sequence":"first","affiliation":[{"name":"School of Dentistry The University of Queensland  Brisbane Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurence J","family":"Walsh","sequence":"additional","affiliation":[{"name":"School of Dentistry The University of Queensland  Brisbane Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,10,5]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1991.tb01128.x"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1399-302x.2001.016005311.x"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1902\/annals.1996.1.1.443"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2002.73.6.597"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2004.75.5.744"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1993.64.7.645"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1988.tb01018.x"},{"key":"e_1_2_8_9_1","first-page":"294","article-title":"Development of a diode laser\u2010based fluorescence caries detector","volume":"32","author":"Hibst R.","year":"1998","journal-title":"Caries Res."},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1159\/000016530"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1159\/000016607"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bdj.4802798"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10103-002-0241-7"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1986.tb02219.x"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1997.68.11.1093"},{"key":"e_1_2_8_16_1","doi-asserted-by":"crossref","first-page":"322","DOI":"10.1002\/j.0022-0337.1992.56.5.tb02641.x","article-title":"Interrater agreement on subgingival calculus detection following scaling","volume":"56","author":"Pippin D.J.","year":"1992","journal-title":"J.
