[Dental trauma protocol--treatment of avulsion and luxation injury].

The goal of this protocol is to provide clear instructions which simplify the process of decision making and treatment of Luxation and Avulsion. In teeth with a closed apex, one should perform root canal therapy at the second appointment in teeth with injuries of luxation and avulsion (except for injuries of subluxation and concussion). The tooth should be reimplanted at site of accident if it possible. For avulsed teeth, the preferred storage medium is milk. One should condition the roots of teeth which have been avulsed. In teeth which have not finished development, the preferred treatment is to allow the continued development of the root.

It's a knockout: survey of the management of avulsed teeth.

Avulsion of a tooth is a not uncommon childhood injury, with up to 16% of dental injuries involving the loss of a tooth. Although this is an apparently 'minor' injury, for a child there may be long-term psychological and treatment problems. Correct advice in the early stages of this injury, and the recognition that prompt treatment may allow a tooth to be successfully reimplanted are vital in the management of these injuries. Often, nursing staff in the accident and emergency or paediatric department may be asked for advice either professionally or informally, and can influence the long-term dental health for these patients. This paper looks at the knowledge of parents and healthcare professionals in the management of these injuries.

Glass-fiber reinforced composite in management of avulsed central incisor: a case report.

Reimplantation failure of avulsed anterior tooth in an adolescent patient requires removal of the failed tooth and consideration of restorative options. These options may include a removable partial denture, conventional 3-unit fixed partial denture, implant, or a resin-bonded appliance with a metal substructure (Maryland bridge). The glass-fiber reinforced composite material (everSTICK, StickTech Ltd, Turku, Finland) offers a restorative solution that is conservative and esthetic when compared to other restorations. Advantages include reduction of cost compared to conventional bridges, saving of time, elimination of second visit, ease of application, absence of metal allergy, ease of cleaning, and naturalness of feel. Its limitations include occlusal factors, and the presence of unsuitable abutment teeth. Another traditional contraindication is the presence of diastemas, which may limit the potential esthetic gains. This case of an 11-year-old girl, addresses the indications, preparation guidelines, and restorative procedures for an everSTICK bridge.

Long-term histopathologic findings in tooth germs autotransplantation. Analysis of a series.

Tooth germ autotransplantation, a surgical technique based upon extraction of a germ followed by reimplantation in the same individual, is indicated in tooth agenesis or loss as an alternative to traditional methods of treatment. The success of autotransplantation relies on several factors, and clinical studies indicate that results are excellent if correct surgery is carried out. This work offers a morphological contribution to the understanding of post-transplantation changes of the pulp, periodontal ligament and root cementum.

Reversible and irreversible effects of temperature on amelogenesis of hamster tooth germs in vitro.

Hamster first hamster molar tooth germs in early secretory stage of amelogenesis were cultured for one day in vitro at 6 degrees C, 22 degrees C, 37 degrees C or 45 degrees C in the presence of 3H-proline, 45Ca and 32P-orthophosphate. Other explants were cultured without these labels and after culture examined by histology. The highest temperature tested was lethal to the explants, decreased total dry weight and rapidly increased total uptake of the radiolabelled mineral ions, probably merely due to physicochemical modification of the existing preculture minerals. Optimal synthesis and secretion of amelogenins were measured at physiological temperature (37 degrees C). Effects of exposure to both temperatures below the physiological value were virtually reversible when explants were grown at physiological temperature (37 degrees C) for another day. However, amelogenin secretion during this recovery period did not reach values as high as those found for the first day in explants initially grown at physiological temperature during the first day. We concluded from the four temperatures examined that the optimal temperature for enamel matrix deposition in vitro was 37 degrees C. At this temperature enamel biosynthesis and its secretion are high. Lowering the temperature slows down the metabolism without any apparent harmful effect. Normal development of the tooth explants in vitro resumes when the culture temperature is restored to physiological levels (37 degrees C). For temporary storage of tooth germ explants prior to any reimplantation, we therefore recommend a temperature of 6 degrees C.

Tissue-engineered hybrid tooth and bone.

Tooth loss accompanied by alveolar bone resorption presents a significant clinical problem. We have investigated the utility of a tissue-engineering approach to provide corrective therapies for tooth-bone loss. Hybrid tooth-bone tissues were bioengineered as follows. Tooth implants were generated from pig third molar tooth bud cells seeded onto polyglycolide (PGA) and polyglycolide-colactide (PLGA) scaffolds, and grown for 4 weeks in the omenta of adult rat hosts. Bone implants were generated from osteoblasts induced from bone marrow progenitor cells obtained from the same pig, seeded onto PLGA fused wafer scaffolds, and grown for 10 days in a rotational oxygen-permeable bioreactor system. The tooth and bone implants were harvested, sutured together, reimplanted, and grown in the omenta for an additional 8 weeks. Histological and immunohistochemical analyses of the excised hybrid tooth-bone constructs revealed the presence of tooth tissues, including primary and reparative dentin and enamel in the tooth portion of hybrid tooth-bone implants, and osteocalcin and bone sialoprotein-positive bone in the bone portion of hybrid tooth-bone constructs. Collagen type III-positive connective tissue resembling periodontal ligament and tooth root structures were present at the interface of bioengineered tooth and bone tissues. These results demonstrate the utility of a hybrid tooth-bone tissue-engineering approach for the eventual clinical treatment of tooth loss accompanied by alveolar bone resorption.
