Teeth were extracted, measured, and mounted in a resin block, and then radiographic template was used to standardise the sensor\u2010target distance (30\u2009cm). The apparent tooth length (APTL) was obtained from the computer screen by means of an electronic ruler accompanying the digital radiography software (CDR 2.0), whereas the actual tooth length (ACTL) was obtained by means of a digital calliper following extraction. Data were compared to the ACTL by variance analysis and Pearson\u2019s correlation test. <jats:italic>Results.<\/jats:italic> The values for APTL obtained from <jats:italic>in vivo<\/jats:italic> radiography were slightly underestimated, whereas those values obtained from <jats:italic>ex vivo<\/jats:italic> were slightly overestimated. No significance was observed (<jats:italic>P<\/jats:italic> \u2264 0.48) between APTL and ACTL. <jats:italic>Conclusion.<\/jats:italic> The length of primary teeth estimated by <jats:italic>in vivo<\/jats:italic> and <jats:italic>ex vivo<\/jats:italic> comparisons using digital radiography was found to be similar to the actual tooth length.<\/jats:p>","DOI":"10.1155\/2015\/939045","type":"journal-article","created":{"date-parts":[[2015,2,23]],"date-time":"2015-02-23T23:13:55Z","timestamp":1424733235000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Digital Radiography for Determination of Primary Tooth Length: <i>In Vivo<\/i> and <i>Ex Vivo<\/i> Studies"],"prefix":"10.1155","volume":"2015","author":[{"given":"Maria D.","family":"Basso","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabiano","family":"Jeremias","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rita C.
