Abstract

Abstract— This paper is a review of the clinical findings from my thesis “Pulp survival and hard tissue formation subsequent to dental trauma”. Traumatic injuries in children and adolescents are a common problem, and the prevalence of such injuries has increased over the last 10–20 years. The purpose of the present investigations was to evaluate the long‐term results following uncomplicated crown fractures and luxations involving subsequent pulp canal obliteration. A total of 241 patients with 545 injured teeth were available for clinical examination, of whom 102 answered a questionnaire and were interviewed before oral examination. In addition, 82 permanent incisors presenting with pulp canal obliteration were followed for a period of 7 to 22 years (mean 16 years). The findings showed little pulpal response to crown fracture and subsequent restorative procedures as long as there was no concomitant periodontal injury (15‐year follow‐up). Approximately every fourth resin composite filling was rated as unacceptable at clinical examination. The interview showed that half of the individuals were dissatisfied with the color and/or anatomic form of the composite restoration. Pulp canal obliteration was found in all luxation categories, and 69% of the teeth demonstrated yellow crown discoloration. According to the survival curve the 20‐year pulp survival rate diagnosed radiographically was 84%. Although the risk of pulp necrosis increased with time, routine endodontic intervention of teeth with ongoing pulp canal obliteration of the root canal did not seem justified.

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.
