Clinical outcomes for permanent incisor luxations in a pediatric population. II. Extrusions
Open accessAbstract
Abstract – A longitudinal outcome study was undertaken to identify variables that significantly influenced outcomes for extruded permanent maxillary incisors of children and adolescents. Clinical and radiographic data was available for 35 patients (18 males, 17 females) representing 55 incisors. Mean age at the time of injury was 10.6 years (range: 7.1–17.8 years). Mean time elapsed to follow up was 1320 days (range: 423–2887 days). Survival analysis was used to identify variables significantly related to the prognosis of these teeth. The loss of an incisor following extrusion was uncommon as only one tooth (1/55) required extraction. There was no statistically significant difference in survival between severely extruded teeth and avulsions that had been stored in physiological media (P > 0.10). Pulp necrosis (PN) was the most common complication following injury (43%) and it most often occurred during the first year. Although not statistically significant, a trend towards increased PN was found with more severely extruded teeth (P = 0.20, relative risk = 2.08). Pulp canal obliteration (PCO) was the second most common outcome (35%). The degree of extrusion was proven to be significantly associated with the development of PCO (P = 0.03, relative risk = 0.33). Root resorption was an uncommon outcome (3/55). This study represents the first outcome data on extrusions to permanent maxillary incisors in an exclusively pediatric population.

In the citing paper
“The combined data from three studies (Andreasen et al. [12], Lee et al. [17], Hecova et al. [14]) concerning 191 teeth repositioned after extrusions, of which not all parameters have been indicated (e.g., time from trauma, severity of luxation), showed 115 teeth with pulp involvement. Of these teeth, 53 (27.74% of the total) developed PCO and 62 (32.46%) PN (Table 6).”

In the citing paper
“They reported 53 teeth with PCO, of which 40 had OA (75.47%) and 13 CA (24.53%); of the total 62 teeth showing PN, 15 had OA (24.19%) and 47 CA (75.81%).”

In the citing paper
“Andreasen et al. [12] report a single case out of a total of 48 (approx. 2%), while Lee et al. [17] report 2 cases among 55 extruded teeth (approx. 3.6%). Hecova et al. [14] do not refer to these data.”

In the citing paper
“Our data, albeit referring to a small sample, confirm what has been reported in the literature [12,14,17], namely that the healing response of teeth following extrusive luxation depends very much on the stage of root development and the severity of the dislocation.”

“Drawn from the papers of Andreasen et al. [12], Lee et al. [17], and Hecova et al. [14], these data confirm the extreme rarity of this complication.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
