  • The purpose of this investigation was to evaluate, by means of a questionaire, the parental awareness of the emergency management of avulsed teeth in children. 297 parents were surveyed during a six week period at Yooseuk elementary school in Seoul. The results indicated that the person who experianced a avulsion of teeth was 16.6%. 35% of parents would attempt replantation of an avulsed tooth but further questioning showed they did not know the correct procedures. 36% of parents were unaware of adequate time for emergency dental services. 62% of parents felt they should seek professional help urgently following an avulsion injury, but their knowledge of transport media for the tooth was poor. Only 8% of parents knew that milk was the medium of choice for both washing and transporting an avulsed tooth. 76% of parents surveyed had never received advice in what to do in the event of an accident where a tooth was avulsed. This study revealed the need for educational campaigns aimed at parents to increase their knowledge of the emergency procedures required when a tooth is avulsed.

  • A material of 48 patients with 60 avulsed and replanted permanent teeth were followed retrospectively in the period of 1996. 1 to 1998. 12 (mean observation period=1year 7months). The age of the patients at the time of replantation ranged from 9 to 63 years (mean=24 years). Clinical records of patients were reviewed to obtain valid data concerning the extent of injury and treatment provided. Pulpal and periodontal healing states were examined with periapical x-rays and clinical examination procedures (i.e. percussion test and mobility test) at their recall visit. Root ankylosis was found in fifty-two teeth(87%) and root resorption in twenty-four(40%). Only two of the replanted teeth(3%) showed partial regeneration of the periodontal ligament. Six teeth(10%) resulted in tooth loss, but the remaining fifty-four were clinically well functioning. Most of teeth have mild marginal bone loss accompanied by gingival retraction without pathological periodontal pockets. The incidence of root resorption was much higher in younger age group. However, it was not affected by the interval between avulsion and replantation, the condition of supporting tissues, the degree of root formation and the type of splinting, indicating that multiple factors involved in determining the prognosis of replanted teeth. Based on these findings, avulsed teeth in unfavorable conditions (i.e. long extra-alveolar periods, etc.) should be preserved if possible.

  • The treatment of complete avulsed teeth due to traumatic injuries is replantation procedure. The major complication of replantation are pulp necrosis, ankylosis, and root resorption. It is important to maintain the vitality of periodontal ligament to minimize the complications. The purpose of this case report is to consider the facts that affect the success rate and the prognosis of complete avulsed teeth after replantation. All of these cases had different conditions and transport media. The following results were observed: 1. The successive treatment of complete ayulsed teeth requires the maintainance of vitality of periodontal ligament. 2. The complication of replantation are inflammatory root resorption and ankylosis and in such case, proper endodontic treatment using calcium hydroxide medications and periodic observations are needed. 3. In case of delayed replantation, the use of fluoride and root planning procedure can help to achieve better result. 4. It is more esthetic and functional to maintain the avulsed tooth in mouth.

  • The aim of this study was to assess the awareness of caregivers, emergency medical technicians, and emergency medical doctors by investigating the storage media for avulsed teeth at the trauma site. This study was performed by reviewing medical records of 183 patients with the age under 17 years old, who visited Ajou University Hospital for dental trauma. Based on their medical records, storage media for avulsed permanent teeth were investigated by classifying them as dry, milk, saline, saliva and tap water. The storage media chosen by caregivers at the trauma site were classified as cases by parents and school nurse teachers. Storage media chosen by emergency medical technicians and emergency medical doctors were also investigated using the same classification criteria. The results show that both parents and school nurse teachers used milk the most as a storage medium for avulsed teeth. Dry storage was the second most chosen medium by parents, and saline by nurse teacher. As a storage media emergency medical technicians used saline the most, while emergency medical doctors used only saline when they failed to replant avulsed teeth. There is a need to improve the knowledge of caregivers, emergency medical technicians, and emergency medical doctors regarding the storage media for avulsed teeth.

  • From the standpoint of general guidelines of a dentist, the following conditions should be considered before replanting a permanent tooth. The avulsed tooth should be without advanced periodontal disease. The alveolar socket should be reasonably intact in order to provide a seat for the avulsed tooth. The extra-alveolar period should be considered, i.e. periods exceeding. 2 hours are usually associated with marked root resorption. But, the above mentioned regulations are often difficult to keep in the actual situation of the medical emergency room, owing it to the delay of primary medical care in multiple trauma patients. The successful cases have been reported with minimal root resorption in the long-term periods, in spite of extra-alveolar periods of several hours and combined alveolar bone fracture. This is a case report regarding the effect of endodontic drainage in delayed replantation after a prolonged extra-alveolar period of the avulsed teeth with alveolar bone fracture.

  • Calcium hydroxide (CH) is the gold-standard intracanal dressing for teeth subjected to traumatic avulsion. A common complication after the replantation of avulsed teeth is root resorption (RR). The current review was conducted to compare the effect of CH with that of other intracanal medications and filling materials on inflammatory RR and replacement RR (ankylosis) in replanted teeth. The PubMed and Scopus databases were searched through June 2018 using specific keywords related to the title of the present article. The materials that were compared to CH were in 2 categories: 1) mineral trioxide aggregate (MTA) and endodontic sealers as permanent filling materials for single-visit treatment, and 2) Ledermix, bisphosphonates, acetazolamide, indomethacin, gallium nitrate, and enamel matrix-derived protein (Emdogain) as intracanal medicaments for multiple-visit management of avulsed teeth prior to the final obturation. MTA can be used as a single-visit root filling material; however, there are limited data on its efficacy due to a lack of clinical trials. Ledermix and acetazolamide were comparable to CH in reducing RR. Emdogain seems to be an interesting material, but the data supporting its use as an intracanal medication remain very limited. The conclusions drawn in this study were limited by the insufficiency of clinical trials.

  • Objectives : To Compare the degree of survival rate of gingival fibroblasts, which is concerned with teeth adherence based on the type of avulsed tooth's storage solution. Methods : Different media gingival fibroblasts were stored in Dulbecco's modified Eagle's medium(DMEM), Hank's balanced salt solution(HBSS), milk, saline, and green tea in for 1, 2, 3 hours. And, MTT assay was conducted to compare survival rate of human gingival fibroblasts. Results : 1. The survival rate of gingival fibroblasts in DMEM and HBSS was higher than thoes in other storage media( Milk> Saline> Green tea). 2. The survival rate of gingival fibroblasts in milk, saline and green tea decreased as time passed. 3. Because of low osmotic pressure, green tea showed decrease of survival rate of gingival fibroblasts. Conclusion : DMEM and HBSS were the most effective storage media for gingival fibroblast. Among milk, saline, green tea, milk is most effective storage media for keeping gingival fibroblasts. Milk is recommended for storage media of avulsed tooth for keeping viability of cells.

  • Purpose: Avulsed tooth can be completely recovered, if sound periodontal ligament (PDL) of tooth is maintained. Although a lot of storage solutions have been explored for the better storage of avulsed tooth, there is a shortcoming that the preservation time is much short. On the other hand, there has been studies that (-)-epigallocatechin-3-gallate (EGCG), the most abundant polyphenol in green tea, which is related to the anti inflammatory, antioxygenic, and antibacterial effects, allows the successful preservations of tissues and cells. This study evaluated the effect of EGCG on avulsed-teeth preservation of Beagle dogs for a period of time. Methods: The atraumatically extracted teeth of Beagle dogs were washed and preserved with 0/10/$100\;{\mu}M$ of EGCG at the time of immediate, period 1 (4 days in EGCG-contained media and additional 1 day in EGCG-free media), period 2 (8 days in EGCG-contained media and additional 2 days in EGCG-free media) and period 3 (12 days in EGCG-contained media and additional 2 days in EGCG-free media). Then, the cell viabilities of preserved teeth was calculated by dividing optical density (OD) of 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay with OD of eosin assay to eliminate the measurement errors caused by the different tissue volumes. Results: From the results, the immediately analyzed group presented the highest cell viability, and the rate of living cells on teeth surface decreased dependent on the preservation period. However, the $100\;{\mu}M$ of EGCG-treated group showed statistically significant positive cell activity than EGCG-free groups throughout preservation periods. Conclusions: Our findings showed that $100\;{\mu}M$ EGCG could maintain PDL cell viability of extracted tooth. These results suggest that although EGCG could not be a perfect additive for tooth preservation, it is able to postpone the period of tooth storage. However, further in-depth studies are required for more plausible use of EGCG.

  • Intubation may lead to several dental complications. Furthermore, a tooth damaged during intubation may be subsequently dislocated. In the present case, the upper primary incisor was avulsed during intubation and, unbeknownst to the anesthesiologist, displaced to the larynx. We report here on the findings and indicate appropriate treatment. Intubation for general anesthesia in children can result in tooth damage and/or dislocation of primary teeth with subsequent root resorption. Prevention is key, and thus it is critical to evaluate the patient's dental status before and after intubation. Furthermore, anesthesiologists and dentists should pay close attention to this risk to prevent any avulsed, dislocated, or otherwise displaced teeth from remaining undetected and subsequently causing serious complications.

  • Traumatic injuries to immature permanent teeth are common and the results can be destructive. Although Hertwig's epithelial root sheath is usually sensitive to trauma, it may resist damage from trauma thereby retaining its vitality and continuing to calcify a root under favorable conditions. This case report describes two cases of trauma to immature permanent incisors. The first case presents an avulsed maxillary central incisor which has been replanted. The other case shows completely avulsed mandibular central incisors which have not been replanted. However, both cases subsequently show continued growing roots separated from the main roots. This report highlights the ability of the immature pulp tissue to continue to form dentin and the robustness of Hertwig's epithelial root sheath to initiate root development despite a traumatic injury.
