Root canal treatment was performed in 48 dark discolored asymptomatic primary incisors following trauma. Twenty\u2010five of them [root canal treatment (RCT) group] were followed till eruption of their permanent successors. Ninety\u2010seven dark discolored asymptomatic primary incisors were left untreated and invited for periodic clinical and radiographic examination. Of these, 28 [follow\u2010up (FU) group] were followed till eruption of their permanent successors. The parameters examined included early extraction of the traumatized primary incisor, early or delayed eruption of the permanent successors, ectopic eruption of the permanent successor and signs of enamel hypopcalcification or hypoplasia in the permanent successor. Chi\u2010square test was used for statistical analysis. Seven of 25 (28%) of the RCT group and 32% (nine of 28) of the FU group required early extraction. Five of 25 (20%) of the RCT group and 21% (six of 28) of the FU group showed early or delayed eruption of the permanent successors. Sixteen of 25 (64%) of the RCT group and 79% (22 of 28) of the FU group showed ectopic eruption of the permanent successors. Enamel hypopcalcification or hypoplasia in the permanent successors was equally found (36%) in both groups (nine of 25 in the RCT group and 10 of 28 in the FU group). None of differences was statistically significant. Root canal treatment of primary incisors that had change their color into a dark\u2010gray hue following trauma with no other clinical or radiographic symptom is not necessary as it does not result in better outcomes in the primary teeth and their permanent successors.<\/jats:p>","DOI":"10.1111\/j.1600-9657.2006.00346.x","type":"journal-article","created":{"date-parts":[[2006,1,11]],"date-time":"2006-01-11T14:40:07Z","timestamp":1136990407000},"page":"14-17","source":"Crossref","is-referenced-by-count":30,"title":["Long\u2010term effect of different treatment modalities for traumatized primary incisors presenting dark coronal discoloration with no other signs of injury"],"prefix":"10.1111","volume":"22","author":[{"given":"Gideon","family":"Holan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,1,11]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"534","article-title":"Discoloration.
