Orthodontic treatment for an adolescent with a history of acute lymphoblastic leukemia.

This case report describes the treatment of a Class I malocclusion that involved ectopic position of the maxillary permanent left canine and the mandibular permanent right second molar. The patient was an adolescent who presented with a medical history that was remarkable for diagnosis and treatment of acute lymphoblastic leukemia (ALL). Dental history was remarkable for significant, generalized shortened roots that were more severe in the mandibular arch. The treatment included fixed appliance therapy in the maxillary arch only and surgical luxation of the mandibular second molar. Successful integration of the maxillary permanent left canine was accomplished without excessive flaring of the maxillary permanent incisors or disruption of the buccal segment occlusion. The risk of external root resorption on teeth with abnormal root morphology, as a result of fixed appliance therapy, should be weighed against the relative benefits that are expected from treatment.

[Semi-rigid bracket splinting of teeth after traumatic luxation].

We describe a non-rigid procedure using brackets for splinting teeth after traumatic avulsion. This type of appliance preserves alveolodental ligament physiology and enables immediate mastication without occlusal obstruction. Installation is easy, except when severe bleeding or alveolar fracture occurs.

Postreplantation management of avulsed teeth: an endodontic literature review.

Today's dental treatment goals are directed at reducing the incidence of root resorption resulting from periodontal ligament devitalization or pulp necrosis. Although the American Association of Endodontists recommends the use of long-term therapy, short-term therapy may be utilized with confidence in well-defined clinical applications. Early final obturation with gutta-percha will increase the long-term prognosis in those cases where patient motivation is questionable or long-term follow-up prior to obturation is not possible. However, where inflammatory resorption is already present, long-term calcium hydroxide therapy is indicated. Long-term post treatment follow-up is imperative in both calcium hydroxide therapies.

Tissue engineering in periodontics using rhBMP-2.

The results of these studies show that rhBMP-2 clearly enhances regeneration in periodontal defects (Figures 2&3). The extent of regeneration appears to be significantly influenced by the nature of the carrier material used to deliver the rhBMP-2 to the periodontal wound. While the positive effects of rhBMP-2 on osteogenesis are well established, less is known about the way in which rhBMP-2 effects cementogenesis, or its role in the formation of a new periodontal ligament. From the studies reviewed, it would appear that rhBMP-2 facilitate in the formation of cellular cementum on previously denuded root surfaces. This newly formed cementum has also been shown to support an organised periodontal ligament attachment. Mechanisms related to the possible role of rhBMP-2 in ankylosis are presently unclear and will require further investigation as such sequelle may complicate the clinical utility of rhBMP-2 in periodontal regeneration. Root resorption has also been reported in the above mentioned studies and appears to be related to the concentration of rhBMP-2. Further research directed at understanding how different carriers influence the way in which the rhBMP-2 is released during wound healing should assist researchers with how to best apply these bioengineered proteins to ultimately achieve a more predictable regeneration of the periodontal attachment apparatus. Moreover, additional research into the differing biologic effects of other members of the BMP family of proteins may also hold further promise in the application of this technology to periodontal regeneration.

[Complications of injuries to the deciduous teeth. Clinical and radiographic evaluation. Perspectives on management and prevention. Apropos of 4 cases].

The traumatisms of primary teeth have often sequels thereabouts grave on the germs of their successional permanent teeth. They have many causes but they are above all frequent during the child's walking trial. We have carried out a clinical and radiographic study of some cases. The study has ascertained the fact that the diversity of the sequels and their gravity depend on the age of the occurring of the traumatism, the intensity and the direction of the shock. The therapeutic and preventive management of these traumatisms and their possible sequels use a pluridisciplinary protocol based on the strict application of indicated treatments, the clinical and radiographic regular follow up and the adoption of a rigorous preventive attitude by the parents during the target period of walking trial.

[Biology of root resorption process in deciduous teeth. Review of the literature].

Aim of this paper, is to examine, with a review of the literature the different aspects of physiological process of root resorption of deciduous teeth. The process of development of mouth and teeth and their structure is also described. Studies made during the last period, in most part by Japanese authors, improved our knowledge about the process of root resorption of deciduous teeth, even if many aspects are still unknown. The involvement of the pulp and the periodontal ligament and the presence of enzimatic activity and immunologic cells have been confirmed; all these elements seem to have a definite role in the process of root resorption of the deciduous teeth.

Development and treatment of retrograde peri-implantitis involving a site with a history of failed endodontic and apicoectomy procedures: a series of reports.

Osseointegrated implants provide predictable restorative support for crowns, restorations, prosthesis abutments, and removable dentures. Their widespread use in recent years has produced different types of complications. Retrograde peri-implantitis, a lesion occurring at the periapical area of an osseointegrated implant, has recently been described. This paper presents a series of reports describing the occurrence and management of retrograde peri-implantitis involving implants replacing teeth with histories of failed endodontic and apicoectomy procedures.

Replantation of avulsed primary incisors: a risk benefit assessment.

Parents of preschool children with avulsed primary incisors may request replantation. Although dental textbooks uniformly recommend that primary teeth not be replanted, some case reports advocate the procedure. This review of case reports identifies a number of pathological outcomes of replantation and provides information for clinicians and parents on the risks that may accompany replantation.

Mandibular cheek tooth development and its relationship to age in young Friesian cattle.

The oral and intra-osseous development of each of the six manidibular cheek teeth found in the permanent dentition of cattle was studied. The animals used were all British Friesians, of varying sex, and slaughtered at different weights at ages between 13 and 22 months. The various stages of development observed in each tooth together with the mean age and age range at which they were seen are recorded. Significant differences were found between the ages at which several of the developmental stages were seen in most of the teeth and indicated that tooth formation in the Friesian cattle studied tended to fall within well defined age limits.

A mixture of Ca(OH)2 paste and ZnO powder as a root canal filling material for primary teeth: a preliminary study.

The present pilot study was conducted on five primary mandibular second molars requiring endodontic treatment to evaluate the clinical and radiographic success of root canal filling material which was a mixture of calcium hydroxide paste (1 cm), Zinc oxide powder (15 gms) and distilled water using hand operated lentulo spirals. All the five cases on clinical evaluation after 2,4,6,9, and 12 months were found to be asymptomatic with no history of pain, tenderness or abnormal mobility. Immediate post-operative radiographic evaluation revealed adequate root canal filling in all cases. The obturated material remained upto the apex of root canals till the beginning of physiologic root resorption. The roots of the primary teeth as well as the filling material mentioned above were seen to resorb at the same rate in one case.
