Evaluation of 71 replanted teeth

Data on children with dental trauma who presented for treatment at the Department of Dentistry for Children and Orthodontics in Budapest over a period of 15 years were analysed. The WHO guidelines were used to classify the traumatic injuries. A total of 590 children were involved, 810 teeth being affected. Children aged 7-14 years made up 88% of the cohort. The male:female ratio was 58:42. The permanent:primary ratio for the affected teeth was 90:10. The teeth most commonly affected were the maxillary central incisors. In 70% of the cases, only one tooth was traumatised. The incidence of dental trauma peaked at 10 years of age. The most common injury type observed was enamel-dentin crown fracture. The decreasing sequence of frequency of etiological factors was playing, sports, falls, cycling, road accidents and fighting. Of the accidents, 65% occurred at school or at home. Seventy seven per cent of the patients presented for medical care in the first 3 days after the accident.

“…However, successful replantation requires successful management of both damaged periodontal and pulpal tissues . Despite the treatment provided, 21–89% of replanted teeth are eventually lost and have the poorest outcomes of all dento‐alveolar traumas . Factors that affect the success of the replantation procedure include the type of storage medium, extra‐alveolar time, the degree of damage to the periodontium, the condition of the pulp, and the degree of root development .…”

Pulp canal obliteration after replantation of avulsed immature teeth: a systematic review

“…Frequeney of PDE healing eenters around 25% with range from 11% to 50% (1-12) ( Table 1). Apart from a link to the length of the total extra-alveolar period, where an extended extra-alveolar period was found to be related to frequent root resorption (1)(2)(3)(6)(7)(8)(9)(10)(11)(12)(13)(14), definite relationships to extraalveolar eonditions or treatment factors have not been established. This has been due to the limited number of teeth in each study (usually around 50).…”

400 avulsed and replanted permanent teeth were examined for periodontal ligament (PDL) healing, using standardized radiographic and clinical examination procedures (i.e. percussion test and mobility test). The effect of various clinical factors was examined, such as age and sex of the patient, type of tooth replanted, presence of crown fracture or bone fracture, stage of root development (including apical diameter and length of the pulp), type and length of extra-alveolar storage, clinical contamination of the root surface, type of root surface cleansing procedure, type and length of splinting period and antibiotic therapy. Surface resorption was generally diagnosed after 12 months; while inflammatory resorption and replacement resorption (ankylosis) were usually observed after 1 month and 1-2 months respectively. Most resorptive processes were diagnosed within the first 2-3 years. However, although rarely, even after 5 and 10 years new resorptive processes could be diagnosed. A univariate statistical analysis of 272 teeth revealed 9 factors significantly related to PDL healing. A subsequent multivariate analysis revealed that the following 4 factors had the strongest impact upon PDL healing, in descending order of significance: Stage of root development; length of the dry extra-alveolar storage period; immediate replantation and length of the wet period (saliva or saline storage). Nonphysiological storage, such as homemade saline and sterilizing solutions (chloramine and alcohol) always led to root resorption. Storage in tap water for more than 20 minutes usually led to root resorption. The common denominator for all these factors related to PDL healing appears to be survival of the PDL cells along the root surface. Based on these findings, immediate replantation is recommended irrespective of stage of root development.
