Evaluation of surgical-orthodontic treatments on impacted mandibular canines

Objective: The aim of the study was to evaluate patients treated for impacted mandibular canines through a combined surgical and orthodontic approach.Study Design: The cases which were made button operations of impacted mandibular canines were selected from5100 panoramic radiographs taken from patients who made use of our oral and maxillofacial surgery services between January 1998 to April 2006. All of these selected patients were assessed radiographically. Pertinentinformation such as sex, age at the time of surgery, site of the unerupted tooth, space availability and any other associated pathoses were also recorded. These patients were called again, and the condition of the mandibular canines was evaluated with panoramic radiographs. If the tooth erupted in the right position and it was functional and asymptomatic, we assumed the treatment to be successful clinically.Results: In the present study, from 5100 patients, 69 patients had impacted mandibular canines and only 21 patients’teeth (a total of 23 teeth) were treated orthodontically. Sixteen impacted mandibular canine teeth of 14patients erupted successfully. Two impacted canine were extracted, and only one canine tooth was transplanted to the normal position. Four patients ended the treatment because of failure of eruption.Conclusion: If a mandibular canine tooth is impacted, not only is surgical exposure sufficient but also tractionforce must be applied orthodontically after the surgical exposure. In addition, age influences the success of the treatment on impacted mandibular canine teeth more than the position and impaction level of the teeth (AU)

Simultaneous occurence of compound odontoma and arrested root formationas developmental disturbances after maxillofacial trauma: A case report

Traumatic injury to a primary tooth and/or a bone fracture has the potential to damage the underlying permanenttooth germ which may disturb its development. The extent of the malformation depends on the developmentalstage of the permanent tooth and the intensity of the trauma. The presence of infection may be a predictive factorfor these abnormalities. Open surgical procedures can also potentially cause impaction and developmental disturbances.Several developmental alterations such as discolouration, hypoplasia, crown dilaceration, root angulationor dilaceration, sequestration of permanent tooth buds and disturbance in eruption have been reported in permanentteeth after trauma. However, odontoma-like malformations and partial or complete arrest of root formationare rare complications developed after trauma. This article presents a rare case with simultaneous occurrence ofan odontoma-like malformation and complete and partial arrested root formations as the results of maxillofacialtrauma. Almost all pediatric fractures must be managed with closed reduction as much as possible. However, if itis necessary to perform an open reduction, careful attention must be paid during placement of the osteosyntheticplates and screws; and tooth bud development must be followed periodically (AU)
