First, occurrence and clinical characteristics of pulp polyp were assessed followed by a descriptive analysis and categorical tests of association. Secondly, a case\u2013control design was used, and the occurrence of pulp polyp was set as the outcome. In third phase, the occurrence of pulp polyp after fracture with pulp exposure was investigated as a variable possibly associated with clinical decision\u2010making (dental extraction\/endodontic treatment). Logistic regression analyses were used, and odds ratios and 95% confidence interval (<jats:styled-content style=\"fixed-case\">OR<\/jats:styled-content>; 95% <jats:styled-content style=\"fixed-case\">CI<\/jats:styled-content>) were calculated in second and third phases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Occurrence of pulp polyp in traumatized primary teeth was of 2.3%.

Children up to 2\u00a0years of age had more chance of having pulp polyp in comparison with older children (3.15; 1.15\u20138.64). Teeth with crown\u2013root fracture had more chance of dental extraction in the therapeutic approach than the teeth with only crown fracture (4.36; 1.10\u201317.32).
