Hence, the objective of this study was to evaluate histopathological and bacteriological changes occurring in dental tissue and periradicular tissue of crown\u2010fractured teeth with pulpal exposure. Twenty\u2010four anterior teeth (central and lateral incisors) from the maxillary teeth of four young, adult Mongrel dogs were used. At 48 and 72\u2003h after performing the crown fractures, the animals were sacrificed and the results evaluated. Both observation periods revealed the existence of an area of superficial inflammation with the formation of hyperplastic tissue towards the external surface. Intense neutrophilic infiltrate was observed below it. Mean depth of inflammation was greater at 48\u2003h (4633.33\u2003\u00b5m) than at 72\u2003h (3933.33\u2003\u00b5m), perhaps coinciding with the bigger pulp chamber opening (\u00d71332.14\u2003\u00b5m at 48\u2003h vs. \u00d7479.52\u2003\u00b5m at 72\u2003h). Upon approaching the cervical portion, the inflammation became less. Bacterial contamination was constant in all the cases evaluated, worsening the histopathological findings with exposure time. This study demonstrates that when a crown fracture with pulpal exposure is produced, the success in treating it depends partly on how quickly therapeutic treatment is administered.<\/jats:p>","DOI":"10.1034\/j.1600-9657.2002.00075.x","type":"journal-article","created":{"date-parts":[[2003,3,11]],"date-time":"2003-03-11T16:23:19Z","timestamp":1047399799000},"page":"196-205","source":"Crossref","is-referenced-by-count":8,"title":["Consequences of crown fractures with pulpal exposure: histopathological evaluation in dogs"],"prefix":"10.1111","volume":"18","author":[{"given":"El\u00edas","family":"Harr\u00e1n\u2010Ponce","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Holland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e9s","family":"Barreiro\u2010Lois","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Mar\u00eda","family":"L\u00f3pez\u2010Beceiro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Luis","family":"Pereira\u2010Espinel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2002,7,29]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-9657.1995.tb00490.x"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0099-2399(96)80250-0"},{"key":"e_1_2_5_4_2","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1016\/S0011-8532(22)01796-7","article-title":"Evaluation, diagnosis and treatment of the traumatized patient","volume":"39","author":"Josell SD","year":"1995","journal-title":"Dent Clin North Am"},{"key":"e_1_2_5_5_2","first-page":"355","article-title":"Follow\u2010up study of permanent incisors with enamel fractures after acute trauma","volume":"89","author":"Ravn JJ","year":"1981","journal-title":"Scand J Dent Res"},{"key":"e_1_2_5_6_2","first-page":"279","article-title":"Fractured incisors treated by vital pulpotomy.
