ABSTRACT Limited information exists on the impact of pulp obliteration on pulpal vitality of orthodontically treated traumatized teeth. Pulpal condition was examined in 269 traumatized maxillary incisors after orthodontic intrusion (OT group) and in 193 traumatized maxillary incisors without subsequent orthodontic treatment (C group). According to the degree of initial pulp obliteration, the teeth were divided into three categories: teeth without, teeth with partial, and teeth with total pulp obliteration. Teeth in the OT group revealed a significantly higher rate of pulp necrosis than teeth in the C group (p < 0.001). In addition, teeth in the OT group with total pulp obliteration showed a significantly higher rate of pulp necrosis than teeth without (p < 0.001) or only partial pulp obliteration (p = 0.025). The results indicate that traumatized teeth with total pulp obliteration have a higher susceptibility to pulpal complications during orthodontic intrusion than traumatized teeth without or only partial pulp obliteration.

    ABSTRACT: Objective The aim of this study was to investigate whether the growth of soft and bone tissue in children with traumatic tooth loss or agenesis of teeth can be developed reliably, using a new technique of autogenous primary canine transplantation. Materials and methods A total of 10 patients (age 7-13 years) were treated either for trauma or for agenesis (n = 14 primary canine transplants). In addition to the clinical examination, patients were subjected to radiological examinations with regard to root resorption, bone height and soft tissue level. Results With an average survival rate of 87%, the average survival time of the transplants using the Kaplan-Meier estimator was 5.2 years. In all cases, soft tissue and bone growth was effectively developed. Conclusion Autogenous primary canine transplantation is a reliable surgical method for rehabilitating children in the early mixed dentition after traumatic tooth loss, enabling adequate soft tissue and bone growth.

    ABSTRACT: Aim: The aim of the present study was to systematically review the influence of orthodontic force on human dental pulp. Methods and results: The addressed focused question was “Do orthodontic forces affect the human dental pulp?” which was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a specific question was constructed according to the PICO (Participants, Interventions, Control, Outcomes) principle. Databases were explored from 1952 up to and including August 2014 using different combinations of the following keywords: “orthodontic force”; “dental pulp”; “reaction” and “tooth movement”. Literature reviews, letters to the editor, commentaries and case-reports were excluded. Thirty studies were included. Six studies assessed the effect of orthodontic forces on pulpal blood flow and 20 studies investigated the pulpal cellular responses to orthodontic forces. In 4 studies, pulpal responses to orthodontic forces were compared between previously traumatized- and non-traumatized teeth. Conclusions: There is insufficient scientific validation regarding the association between orthodontic forces and human dental pulp. However, a history of dental trauma maybe considered a risk factor for loss of pulp vitality during orthodontic treatment.

    ABSTRACT: AimsThis study aimed to determine the kinds of sequelae resulting from intrusive luxation and subluxative injuries in primary anterior teeth as well as the timing of such sequelae.Materials and methodsIn this longitudinal retrospective study, data were collected from dental records and radiographs of patients with traumatic dental injury (TDI) treated at the Centre for the Study and Treatment of Dental Trauma in Primary Dentition (Pelotas, RS, Brazil). Fifty-two children, with seventy intruded teeth, and 76 children, with 99 subluxated teeth, met the inclusion criteria. Sequelae, such as crown discoloration, fistula, pulp canal obliteration (PCO), inflammatory root resorption (IRR), and internal root resorption, were investigated. The data on the sequelae were distributed into eight follow-up periods: 0–30 days, 31–90 days, 91–180 days, 181–365 days, 1–2 years, 2–3 years, 3–4 years, and >4 years.ResultsThe sample comprised 99 subluxation cases and 70 intruded teeth. Crown discoloration was the most prevalent sequelae. Among the subluxated teeth, <50% of IRR, fistula, crown discoloration, and PCO occurred within 180 days after TDI; however, the sequelae were also diagnosed after longer periods. Majority of sequelae of intrusion were diagnosed within the 181–365 days and 1–2 years periods but were also observed after more than 4 years of follow up.Conclusions For both intrusion and subluxation, trauma sequelae were diagnosed even after the 3–4 years of follow-up.
