Clinical management of the avulsed tooth.

Treatment outside the dental office: Replant immediately after gentle washing if practical. If replantation is not practical, store the tooth in the best medium available. Storage media in order of preference are Hank's Balanced Salt Solution (HBSS), milk, saline, and saliva (buccal vestibule). Water is the least desirable storage medium. Treatment in the office: Emergency visit; Place tooth in HBSS while exam is conducted and history is taken. Prepare socket for gentle repositioning of the tooth. Prepare the root. Extraoral dry time < 20 minutes: Closed apex--replant immediately after gentle washing. Open apex--soak in 1 mg doxycycline in 20 mg saline for 5 minutes. Extraoral dry time 20 to 60 minutes: Soak in HBSS for 30 minutes and replant. Extraoral dry time > 60 minutes: soak in citric acid, 2% stannous fluoride, and doxycycline and replant. Endodontics can be done extraorally. Semirigid splint for 7 to 10 days. (If alveolar fracture is present, rigid splint for 4 to 8 weeks). Suture soft-tissue lacerations, particularly in the cervical area. Administer systemic antibiotics (penicillin V potassium if possible) Chlorhexidine rinses and stringent oral hygiene while the splint is in place (7 to 10 days). Analgesics as required. Second visit after 7 to 10 days: Endodontic treatment: Tooth with open apex and extraoral dry time of < 60 minutes: No endodontic treatment initially. Recall every 3 to 4 weeks to examine for evidence of pathosis. If pathosis is noted, disinfect the pulp space and start apexification procedure. Tooth with open apex and extraoral dry time > 60 minutes: If endodontics was not completed in the emergency visit, start endodontics and follow apexification procedure. Tooth with closed apex: Endodontics should be initiated after 7 to 10 days. Careful chemomechanical instrumentation under strict asepsis. Splint removed at end of visit. Obturation visit: If endodontics was initiated 7 to 10 days after the avulsion, obturation can take place after short-term calcium hydroxide treatment. If endodontics was initiated more than 14 days after the avulsion or inflammatory resorption, long-term calcium hydroxide for 6 to 24 months, obturated when an intact lamina dura is traced. Restorations: Temporary restorations: Should be 4 mm deep. Reinforced zinc-oxide-eugenol, acid-etch composite resin, glass-ionomer cement. Permanent restoration: Placed immediately after obturation. Acid-etch resin and dentin bonding agents. Follow-up care: Twice per year for 3 years and yearly for as long as possible. Late complications are common.

A multicentre investigation into the role of structured histories for patients with tooth avulsion at their initial visit to a dental hospital.

A paper structured history (SH) is a sheet, which prompts or reminds the clinician to ask various important questions. The aim of this study was to examine avulsion cases with respect to the quality of clinical records. Hospitals studied used either a paper SH or had no specific structure in their recording of avulsion details, e.g. unstructured histories (USH). The most important prognostic items that should be recorded for avulsion cases at their first visit were identified by reviewing the literature. Clinical case records meeting strict inclusion criteria were retrospectively analyzed against 10 important prognostic items. Forty-seven patient records were identified in the SH group compared to 43 patient records in the USH group. Using chi-square and Fisher's exact tests, the SH group were significantly better at recording the following: accident details (P < 0.001), loss of consciousness (P < 0.001), other teeth or tooth injuries (P < 0.05), extra-alveolar mediums (P < 0.01), total extra-alveolar time (P < 0.001), antibiotics given at time of injury (P < 0.05) and apical maturity (P < 0.001). In all the dental hospitals selected, two-thirds of the case records were completed by junior dentists not in specialist training and the improvement in history when using an SH form was most pronounced in these groups. It is concluded, therefore, that an SH should be taken for cases ofavulsion as it was significantly better at collecting essential prognostic information.

Fibrous carbon implants for the maintenance of bone volume after tooth avulsion: first clinical results.

When the avulsion of the last teeth of a patient is necessary, we propose to maintain the bone mass in order to improve the prosthetic conditions. For this purpose, we use fibrous carbon which is a biocompatible material well tolerated by the surrounding tissues. The results are reported of 10 yr of clinical use of fibrous carbon roots implanted in 38 alveoli of 26 patients with a mean follow-up of 34 month. There were 26 accepted artificial roots and 12 failures. The causes of failure are principally: (1) absent external bone wall near implanted alveoli (presence of the four bone walls is necessary); (2) existing local inflammation near implant site area.

Evaluation of the topical effect of alendronate on the root surface of extracted and replanted teeth. Microscopic analysis on rats' teeth.

The treatment of choice for tooth avulsion is replantation. The ideal replantation should be realized as quickly as possible, or at least, the avulsed tooth should be kept in an adequate solution to preserve the periodontal ligament attached to the root. If that is not possible, treatment of the radicular surface should be done in order to prevent radicular resorption. The purpose of this study was to test sodium alendronate as a substance for topical treatment of the radicular surface of avulsed teeth in an attempt to prevent the occurrence of dental resorptions. Fifty-four rat maxillary right central incisors were extracted and replanted. Group I--extra-alveolar dry period of 15 min, intracanal dressing with calcium hydroxide (CALEN, S.S. White, Artigos Dentários LTDA, Rio de Janeiro, Brazil) and replantation; Groups II and III - extra-alveolar dry periods of 30 and 60 min, respectively, immersion in 1% sodium hypochlorite for 30 min for removal of the periodontal ligament, washing in saline solution for 5 min, and treatment of the radicular surface with 3.2 mg/l sodium alendronate solution for 10 min. Intracanal dressing with calcium hydroxide and replantation followed. At 15, 60, and 90 days post-reimplantation, the animals were killed and the samples obtained and processed for microscopic analysis. The results indicated that sodium alendronate was able to reduce the incidence of radicular resorption, but not of dental ankylosis. No significant differences were observed regarding variations in the extra-alveolar periods among the groups.

Tooth replantation after traumatic avulsion: a report of ten cases.

This report compares the manner in which the avulsed tooth was handled at home versus at school, and presents the different outcomes of the replanted teeth in both groups. Eighteen of 32 avulsed teeth were not replanted, and four replanted teeth could not be followed. Thus, the material comprised 10 avulsed permanent incisors of 10 traumatized children, aged between 8 and 13 years, who were treated at the Pediatric Dental Clinic of Niigata University Dental Hospital. Half of the patients avulsed the tooth at school and the other half at or near home. Of the five teeth avulsed at school, three were kept under wet conditions. The time until their replantation ranged between 0.5 and 3.5h. Their outcomes were fairly good, except for one incisor that was extracted about 3 years later owing to the undesirable replantation procedures by the dentist. Of the avulsed teeth at or near home, three were left under dry conditions. Their time until replantation ranged scattered between 0.5 and 12h. Of these, two incisors preserved under wet conditions survived without significant root resorption. These results suggested that information about the way to keep the avulsed tooth was relatively well known to school nurse-teachers compared with parents. Depending on the kind of lay people, it appears that it is necessary to select the best way to convey information about the management of avulsed permanent teeth.

Endodontic treatment for children.

Root canal treatment for children has particular difficulties and considerations. It must be planned in light of the remaining teeth, and the need for balancing or compensating extraction borne in mind. Diagnosis may be difficult, as may prolonged treatment under local anaesthesia and rubber dam. Vital pulpotomy techniques with formocresol and/or calcium hydroxide must be carefully executed in line with the UK National Guidelines. The treatment of the avulsed tooth has been the subject of much research, and practitioners should ensure that they are up-to-date with current treatment modalities.

Periodontal healing of extracted dogs' teeth air-dried for extended periods and soaked in various media.

The aim of this study was to determine the periodontal healing of replanted dogs' teeth which, after extended extra-oral dry times, had been soaked in various media before replantation. Incisors and premolars of beagle dogs were root canal treated, extracted and bench dried. The teeth were grouped according to dry times of 30, 45 and 60 minutes. Each group of teeth was soaked in one of three media, Hank's balanced salt solution, ViaSpan (Belzer UW-CSS, Dupont Pharmaceuticals), or Conditioned Medium (supernatant of confluent culture of human gingival fibroblasts) for 30 minutes before replantation. Controls consisted of teeth extracted and replanted without drying on soaking (negative control), and bench-dried teeth replanted without soaking in the media (positive control). The dogs were killed 6 months after replantation of the teeth, which were prepared for histologic evaluation. Five microns cross-sections (every 70 microns) of the root and surrounding tissue were evaluated for healing/resorption according to Andreasen's criteria. The best healing occurred for the roots which had been immediately replanted. Healing in the positive control groups decreased with increased dry time. For the 30-minute dry time groups, soaking in media had no beneficial effect on periodontal healing compared with the controls. Soaking in ViaSpan resulted in an increased healing incidence for both the 45- and 60-minute bench-dried groups while soaking in the other media had no consistent beneficial effect. It appears from this study that an avulsed tooth that has been left dry for 30 minutes should be replanted immediately without soaking. However, teeth that have been dry for 45 or 60 minutes would benefit from soaking for 30 minutes in ViaSpan.

Replantation--a clinical philosophy.

Although prognosis for the avulsed tooth is guarded, replantation, followed by a brief period of splinting and endodontic therapy, is suggested. Minimal extraoral period, minimal manipulation of the root surface and alveolus, and moist storage for the tooth are identified as factors that minimize resorption. Education of coaches, teachers, and all dentists in the technique of replantation is encouraged.
