Saygili S, Gezer I, Oner HS, Tuna-Ince EB, Kasimoglu Y. Evaluation of the reliability and accuracy of YouTube™ and TikTok™ contents about storage media for avulsed teeth: A cross-sectional study. Dent Traumatol 2024. [PMID: 38591807 DOI: 10.1111/edt.12952] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Revised: 03/07/2024] [Accepted: 03/08/2024] [Indexed: 04/10/2024]
Abstract
BACKGROUND/AIMS The preservation of avulsed teeth is critical in dental trauma management, necessitating effective storage media to ensure viable tooth reimplantation. The urgent need for accurate information has led both professional and non-professional individuals to increasingly seek guidance from video-sharing platforms such as YouTube™ and TikTok™. These platforms have become key resources for advice on such dental emergencies, but the reliability and accuracy of this information have not yet been systematically evaluated. This study aimed to assess the quality, accuracy, and reliability YouTube™ and TikTok™ of videos regarding storage solutions for avulsion injuries. MATERIAL AND METHODS A search was conducted on YouTube™ and TikTok™ on February 4th, 2023, using terms related to traumatic dental injuries, and 53 videos were included. Video demographics such as platform, duration, type, upload date, likes, and comments were recorded. Video content quality, reliability, and accuracy were measured using the Global Quality Scale (GQS), Journal of the American Medical Association (JAMA) benchmarks, and Video Information and Quality Index (VIQI). Research data were analyzed using SPSS IBM 24.0 at a 95% confidence interval. RESULTS In total, 53 videos were examined. The average scores were JAMA: 1.70/4.00, modified DISCERN: 54.3/80.00, GQS: 3.88/5.00, and VIQI: 13.8/20.00. According to the modified DISCERN index, there were no "very poor" or "poor" quality videos, 49.05% were "moderate," 22.6% were "good," and 28.3% were "very good." No difference was found between YouTube™ and TikTok™ videos in terms of the modified DISCERN index, JAMA scores, GQS, and VIQI scoring (p > .05). CONCLUSIONS Traumatic dental injuries are a common problem among children, and evaluating the reliability of available contents is becoming crucial for appropriate intervention. The study reveals that despite being sourced mainly from dental professionals, the overall quality of videos on avulsed tooth management was mediocre, underscoring the risks associated with misleading or incomplete information in such critical situations.

Dent Traumatol 2024; 40:195-203. [PMID: 37849392 DOI: 10.1111/edt.12895] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 09/25/2023] [Accepted: 09/26/2023] [Indexed: 10/19/2023]
Abstract
BACKGROUND/AIM Pediatricians play an essential role in managing pediatric oral emergencies; hence, they should have accurate information on dental injuries. This study aimed to assess the knowledge level of pediatricians regarding traumatic dental injuries (TDI) and their awareness of the ToothSOS mobile application. MATERIALS AND METHODS A survey comprising 10 questions was created on Google forms, and the links were sent to the participants via electronic mail and a mobile application. The demographic characteristics and the knowledge level of pediatricians about TDI and their awareness of the ToothSOS mobile application were evaluated. The questions were prepared by following similar studies and the current guidelines of the International Association of Dental Traumatology. RESULTS A total of 229 pediatricians (74.2% female) participated in this study. The correct answer rates revealed statistical differences in terms of profession and experience on the following issues: the most frequently traumatized tooth, the preference of the antibiotic agent, and the management of avulsed primary tooth (p < .05). The decision to consult a dentist revealed statistical differences in the profession (p = .001). The correct answers on the correlation between the age group and dental trauma accompanied by soft tissue injuries showed statistical differences in experience (p = .005). Although none of the participants knew the ToothSOS application, 91.7% of them preferred using this tool in future practices. This rate was statistically higher in participants with an experience of more than 10 years (p = .013). CONCLUSIONS The knowledge level of pediatricians regarding dental trauma was found to be sufficient, except for the questions on avulsion injuries. However, the fact that the participants were unaware of the ToothSOS mobile application was the most considerable result of the study, and this finding highlighted the importance of informing pediatricians dealing with oral injuries regarding the latest updates on dental traumatology.

Abstract
INTRODUCTION Knowledge of bibliometric indices on the avulsion of permanent teeth can help researchers to identify gaps in the literature. The aim of this study was to analyze the bibliometric characteristics of the 100 most-cited articles on the avulsion of permanent teeth. MATERIALS AND METHODS Two researchers conducted an unfiltered search in the Core Collection section of the Web of Science (WoS-CC) database. The following data were extracted: position in the citation list, total number and density of citations, title, authors, institution, country, year of publication, journal, keywords, study design, tooth storage medium, and other topics of interest. Bibliometric networks were generated and analyzed using the VOSviewer software. Descriptive analysis and a Poisson regression analysis were performed (P < .05). RESULTS The number of citations per article varied between 31 and 407. The average was 70.05, and 13 articles received more than 100 citations. J.O. Andreasen (n = 13) and M. Trope (n = 15) were the authors who contributed most often to publications. The United States was the country with the highest number of articles (n = 31). Authors associated with the University of Copenhagen, Denmark (n = 9) and University of North Carolina, USA (n = 10) showed higher productivity. In vitro/animal model studies were the most frequent study designs (n = 50), and the most-discussed topic of interest was prognosis (n = 47). There was strong clustering among 13 research groups. CONCLUSION Observational studies, published by authors from Europe and about prognosis or treatment presented more citation ratio in WoS-CC. Clinical studies on permanent tooth avulsion are needed to increase the quality of scientific evidence and provide insights for health professionals and public policy makers.

Abstract
Dental and dentoalveolar injuries are common in the pediatric population. Management is predicated on the type of tooth injured (primary or permanent), extent of injury, the dental and behavioral age of the patient, and ability of the patient to tolerate treatment. Although many dental injuries occur in isolation, a systematic evaluation of the patient is mandatory to confirm the absence of basal bone fractures of the maxilla or mandible, traumatic brain injury, cervical spine injury, and/or facial soft tissue injury. Long-term follow-up is paramount to achieving a functional occlusion and optimal dental health following injury.

Abstract
AIM The aim of this study was to determine the current level of knowledge and understanding about dental trauma and its management in children among dental practitioners. MATERIALS AND METHODS The study was conducted after obtaining the ethical clearance from the Institutional Review Board (IRB). A structured questionnaire was prepared, which comprised 20 questions and was validated by dental trauma experts. The questionnaire, which covers all aspects of traumatic dental injuries (TDIs) in both primary and permanent dentition, was distributed online to 850 dental practitioners. The questionnaire was open from January 2022 to April 2022, with a 3-month time frame to complete it. The responses were collected and statistical analysis was done using SPSS software. RESULTS The mean age of the participants were 22-30 years. Furthermore, 515 participants were females and 263 were males. In this survey among 784 responses, 449 dentists were trained in dental trauma and 618 participants had personal experience in managing dental trauma. All other questions about knowledge and awareness of dental trauma management received fewer correct answers. CONCLUSION According to the present study, dental practitioners have only mild-to-moderate knowledge and awareness about dental trauma. From the latest the International Association for Dental Traumatology guidelines, dentists need to consistently update their knowledge through dental trauma conferences, workshops, trainings, and symposiums. CLINICAL SIGNIFICANCE This study informs us about the existing level of dental knowledge about dental trauma, which is significantly low. This will considerably boost dental practitioners' interest in TDIs. As a result, practitioners' expertise will grow, allowing them to better care for their patients.

Abstract
Replantation is the treatment of choice for avulsed permanent teeth; ankylosis and cervical root resorption are among survival complications. A 9.5-year-old boy presented with an avulsed maxillary permanent central incisor with an open root apex following a school accident. The tooth was kept in milk, after a dry time of 15-20 min. Its replantation was performed 60 min after the accident. At 8 months, apexification with apical plug was attempted upon radiographic evidence of apical periodontitis. Ankylosis sound with infraocclusion and radiographic evidence of external cervical root resorption (ECR) were evident at 3 years and 3 months. At the patient's return one year later with esthetic concerns (2 mm infraocclusion) there was a 5 mm diameter ECR cavity. After intentional atraumatic extraction the resorptive cavity was debrided and restored with Biodentine; subsequently the tooth was reimplanted and splinted at an extruded position. At the 10-year follow up since the first avulsion the tooth remains esthetically pleasing, asymptomatic, non-ankylotic and functional. The present case supports intentional replantation as an option in managing infraoccluded teeth with advanced ECR.

Abstract
BACKGROUND/AIM Permanent tooth avulsion requires proper management at the time of the accident and parental oral health literacy (OHL) may influence decision-making with regards to dental trauma. The aim of this study was to investigate the influence of OHL on: (1) self-rated comprehension of an information leaflet (IL), (2) self-rated capacity to execute the tasks proposed on the IL, and (3) attitudes regarding the avulsion of a permanent tooth in children. MATERIAL AND METHODS A longitudinal study was conducted involving the reading of an IL by 466 parents/caregivers. Evaluations were performed prior to the IL (Phase I), immediately after the application of the IL (Phase II) and 60 days after the application of the IL (Phase III). Self-rated comprehension and capacity to execute the proposed tasks were analyzed in Phase II. Attitude was evaluated in all three phases. Functional OHL was measured using the BREALD-30 and interactive OHL was measured using HeLD-14. RESULTS Correlations were found between self-rated comprehension and both the OHL/BREALD-30 score (rs = 0.179; p = .012) and OHL/HeLD-14 score (r = 0.258; p < .001). Correlations were also found between the self-rated capacity to execute the proposed tasks and both the OHL/BREALD-30 score (rs = 0.133; p = .047) and the OHL/HeLD-14 score (rs = 0.225; p < .001). Higher BREALD-30 and HeLD-14 scores were associated with a better performance regarding parental attitudes toward permanent tooth avulsion comparing Phases I and II and Phases II and III (p < .05). CONCLUSIONS Higher levels of OHL were associated with better parental self-rated comprehension of the IL and the capacity to execute the tasks proposed therein as well as more adequate attitudes regarding the avulsion of a permanent tooth.

Abstract
Aim For a better prognosis of an avulsed tooth, it is important to store it in an appropriate storage medium prior to replantation. The purpose of this study was to evaluate the ability of ice apples to preserve the viability of periodontal ligament (PDL) fibroblasts. Materials and methods Periodontal ligament (PDL) fibroblasts were procured from the roots of healthy premolars and cultured in Dulbecco's Modified Eagle's Medium (DMEM). They were preserved with-ice apple water (IAW), 30 and 10% ice apple fruit pulp extract (IAFPE), DMEM, negative control without any agent, and positive control DMEM supplemented with fetal bovine serum (FBS). Culture plates were incubated with investigational media at 37°C for 1, 3, and 24 hours. Each experiment was repeated thrice. Assessment of cell viability was done using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide tetrazolium reduction (MTT) assay. After every test period, storage media was removed; 60 µL of MTT solution was added to each well and incubated for 3 hours at 37°C. The supernatant was aspirated and the formazan blue crystals formed were solubilized using dimethyl sulphoxide (DMSO) (100 µL). Optical density was measured at a wavelength of 490 nm. The effects of the test storage media at each time period were evaluated by a one-way analysis of variance (ANOVA) test, and this was followed by post hoc Tukey's multiple comparison tests (p < 0.05). Results A total of 10% IAFPE demonstrated the maximum capacity to maintain PDL cell viability in all three test periods (p = 0.001). Among the different forms of ice apple used in this study, IAFPE showed better results as compared to IAW (p = 0.001). Conclusion Ice apple fruit pulp extract (IAFPE) at 10% concentration showed the maximum capacity to maintain PDL cell viability across all three test periods. Therefore, it can be considered a suitable alternative natural storage medium for avulsed teeth. However, further, more detailed studies are required in this field.

Abstract
Tooth autotransplantation is the treatment modality in which a tooth is transferred from one site to another in the same person. This technique has a history of centuries. However, it is not well-known or well-documented. Essential aspects of the clinical procedure, criteria for performing tooth autotransplantation, advantages, disadvantages, and complications are also discussed in the review. It has been a public health concern considering the prevalence of dental trauma in children, the financial burden of treatment, and the long recovery times associated with dental injuries. There is evidence that tooth autotransplantation is an effective method of restoring missing teeth, particularly for growing children. Even if autotransplantation fails, the soft tissue and bone conditions would likely still be suitable for subsequent implant treatment. Appropriate patient and tooth selection are essential to the technique's success. Other prognostic factors are also discussed. The findings from the available literature suggest that tooth autotransplantation is a viable and cost-effective technique. This paper discusses the literature and protocols the authors implemented for autotransplantation of the tooth.

Intentional Replantation as a Starting Approach for a Multidisciplinary Treatment of a Mandibular Second Molar: A Case Report. J Clin Med 2022; 11:jcm11175111.

Abstract
Intentional replantation (IR) may offer a solution for persistent periapical lesions associated with endodontically treated teeth. A 35-year-old male patient presented with pain associated with the left mandibular second molar and hypoesthesia. Upon clinical examination, increased probing pocket depth in the mid-buccal surface was detected. Cone beam computed tomography revealed a previous non-surgical root canal treatment, with root canal filling material extrusion adjacent to the inferior alveolar nerve, a fractured instrument in the mesial root, and a large periapical radiolucency involving both teeth 37 and 36. A diagnosis of symptomatic post-treatment apical periodontitis was established. After discussing treatment options with the patient, an IR of tooth 37 was performed. Extra-oral procedures were completed in 17 min. At 9 months, hypoesthesia resolution was reported, and apical healing was radiographically observed. After 2.5 years, the replanted tooth showed extensive root resorption. An extraction with alveolar ridge preservation, using leukocyte-platelet rich fibrin (L-PRF), was performed. Six months after tooth extraction and regeneration, implant placement surgery was carried out. IR presents a valid treatment modality for the management of post-treatment apical periodontitis. When orthograde retreatment or apical microsurgery prove to be unfeasible, IR is a unique procedure with the potential to promote tooth preservation in properly selected cases. Although unsuccessful after 2.5 years, the IR of tooth 37 allowed for bone regeneration, the maintenance of tooth 36 vitality, and hypoesthesia resolution.

Abstract
The tooth is stabilized by fiber-rich tissue called the periodontal ligament (PDL). The narrow space of the PDL does not calcify in the physiological state even thought it exists between two calcified tissues, namely, the cementum of the root and alveolar bone. Two situations that require PDL regeneration are periodontitis and dental trauma. Periodontitis induces the loss of PDL and alveolar bone due to inflammation related to infection. Conversely, in PDLs damaged by dental trauma, accelerating bone formation as an overreaction of the healing process is induced, thereby inducing dentoalveolar ankylosis at the tooth root surface. PDL regeneration following dental trauma must therefore be considered separately from periodontitis. Therefore, PDL regeneration in dental trauma must be considered separately from periodontitis. This review focuses on the components involved in avoiding dentoalveolar ankylosis, including oxytalan fibers, aggregated microfibrils, epithelial cell rests of Malassez (ERM), and TGF-β signaling. During root development, oxytalan fibers produced by PDL cells work in collaboration with the epithelial components in the PDL (e.g., Hertwig's root sheath [HERS] and ERM). We herein describe the functions of oxytalan fibers, ERM, and TGF-β signals which are involved in the avoidance of bone formation.

Abstract
We present the treatment of an injured and avulsed incisor (which was afterwards ankylosed), by subapical osteotomy and conventional orthodontic mechanisms. A 9-year-old boy presented for orthodontic treatment with an injured and avulsed central incisor, which, after initial repositioning, ended up with ankylosis and severe root resorption. The case was treated by single tooth alveolar osteotomy and distraction osteogenesis through conventional orthodontics, advocating for the floating bone concept due to the short vertical distance by which the tooth alveolus part had to be relocated. Orthodontic treatment of the avulsed central incisor was completed after osteotomy and distraction osteogenesis, and the tooth was restored to its proper position, aiming to address issues of aesthetics and function for the time being. The patient was finally referred to a prosthodontist for future and final implant rehabilitation due to severe root resorption. Distraction osteogenesis after surgical procedures is a reliable solution for dealing with an ankylosed and submerged tooth.

Abstract
Purpose The prime factor in determining the success of reimplantation of an avulsed tooth is the maintenance of the viability of periodontal ligament fibroblast cells (PDFC). This study aims to evaluate and compare Mc Carey Kaufman media (MK), Cornisol, Dulbecco’s Modified Eagles Medium (DMEM), Hanks Balanced Salt Solution (HBSS) and distilled water in preserving the viability of the PDFC using the Cell Counting Kit-8 assay (CCK-8). Methods Cryopreserved PDFC were suspended in DMEM and incubated in CO2 incubator at 370C with 95% humidity and 5% CO2 for attachment. Once cells attained 80% confluence, they were trypsinised and passed into T-25 culture flasks to expand the culture population. Cells from passage 5 were pooled for experimentation. Trypan blue exclusion test was performed before each experiment to measure cell viability and batches showing more than 95% viability were used in the experiment. The viable PDFC with 1×105 were seeded in 96 well plates and incubated in CO2 incubator at 370C, 95% humidity and 5% CO2 for 24 hours to allow cell attachment. A 100µL of the experimental media were added in the wells and the cells were exposed for 1, 24 and 48 hours respectively. The viability was determined using the CCK-8. Experiment was performed in triplicates and data was subjected to statistical analysis. Results Statistical analysis was performed using repeated measure ANOVA, ANOVA, and post-hoc Bonferroni test with the significance level p<0.05. The values are as follows: MK (1.3146 ±0.0588, 1.9012±0.0511, 2.0723±0.1211) > Cornisol (1.2399±0.0548, 1.9596±0.0652, 1.9592±0.1361) >DMEM (1.1914±0.0691, 1.8479±0.0116, 2.0718±0.0795) > HBSS (0.3665±0.0814, 0.0184±0.0010, 0.0248±0.0042) >distilled water (0.0122±0.0033, 0.0225±0.0085, 0.0104±0.0008) at 1 hour, 24 hours and 48 hours respectively. MK >Cornisol>DMEM>HBSS>distilled water. Conclusion It can be concluded that the corneal preservation solutions showed promising results in preserving periodontal ligament cell viability for extended time periods.

Abstract
The current case report presents a case of a road traffic accident comprising dental avulsion of maxillary incisors. A 30-year-old male reported missing teeth following trauma in his upper front tooth region. The avulsion of maxillary right central and lateral incisors along with laceration in upper and lower lips was evident. The avulsed teeth were stored in milk after a brief extra-oral dry time of one hour and were carried to the department with a one-hour delay. After clinical and radiographic investigations, no mobility or fractures were apparently noticed. The avulsed 11 and 12 had closed apices with intact crown and root surfaces. Following an extra-oral endodontic therapy, immediate replantation was scheduled. Subsequently, the alveolar sockets were irrigated with saline to dislodge the clot and any gross debris that was present. Teeth were reimplanted into the socket after placement of PRF membrane around the root surface. A semi-rigid wire and composite splinting were done for a span of two weeks and antibiotics were prescribed. An exploratory CBCT taken revealed a cortical bone loss in the buccal region of 12 and 11. An interdisciplinary approach to regenerate the osseous defect was then carried out. A follow-up of two weeks, four weeks, three months, six months, and a year was done. Evaluation performed after a year revealed the absence of clinical symptoms and satisfactory healing with no signs of resorption radiographically.

Abstract
BACKGROUND The aim of this study was to evaluate parental and training coaches' knowledge and attitude towards traumatic dental injuries (TDIs) among children. MATERIAL AND METHODS A 31-item questionnaire was distributed to the parents and training coaches attending local sporting clubs in Brisbane region, Australia. The questionnaire consisted of five parts (i) demographic and professional information; (ii) TDIs in the primary dentition; (iii) fractures and subluxation of permanent teeth (iv) avulsion of permanent teeth, and (v) information and knowledge related to the management of traumatized teeth. The jamovi (Version 1.6.3) and GraphPad Prism were used for data analysis. RESULTS A total of 233 participants were surveyed, 211 parents and 22 coaches. Of all types of injuries, parental knowledge of managing avulsion to permanent teeth was poorest (9.5%), followed by management of injuries of primary teeth (17.5%) and management of fractures or subluxation of permanent teeth (29.4%). Parents in health care occupations had higher satisfaction on self-knowledge in managing TDIs however there was no significant difference in knowledge levels between health care personnel and other professions (P = 0.128). There was a discrepancy between the lack of knowledge and willingness to further self-educate with online platforms being the preferred medium. CONCLUSION The study showed a gap in parents' and training coaches' knowledge regarding the management of TDIs among children.

Abstract
AIM Dental injuries are one of the most frequent oral health problems in children and adolescents. This study aimed to evaluate Croatian pediatricians' knowledge and practice regarding dental injuries management and the use of mouthguards as means of protection against traumatic injuries. MATERIALS AND METHODS A questionnaire-based cross-sectional survey conducted among 186 pediatricians examined their demographic characteristics, knowledge and experience with dental injuries. Student t-test or one-way ANOVA, with Tukey's post-hoc were used to analyze obtained data (p ≤ 0.05). RESULTS The overall mean score of knowledge on the management of dental injuries was 3.6 ± 1.53 points. Male pediatricians (p = 0.016), those who witnessed dental injuries (p = 0.003), and those who had more than ten years of pediatric practice (p = 0.027) showed better knowledge. The results of multiple linear regression analysis demonstrated impact between pediatricians' knowledge in the emergency treatment of traumatic dental injuries concerning the level of health care (practice settings) (β = -0.254, p = 0.002) and the number of patients treated by a pediatrician per day (β = -0.187, p = 0.030). CONCLUSION Pediatricians have a low level of knowledge regarding the primary care of traumatic dental injuries. An additional course on dental injurie management should be recommended as part of the physician and pediatricians' educational training.

Abstract
Many storage mediums are available for the storage of avulsed teeth to preserve the viability of periodontal ligament (PDL) cells before replantation; however, it is unclear which medium is the optimal option. We performed this network meta-analysis to answer this question. A comprehensive search was conducted in PubMed, EMBASE, and the Cochrane library to capture eligible studies investigating the comparative efficacy of Hank's balanced salt solution (HBSS), aloe vera gel (AVG), oral rehydration solution (ORS), coconut water, egg white, green tea, propolis, saline, milk, and water. Statistical analysis was conducted using Review Manager v5.3 and ADDIS v1.16.8. In total, 20 RCTs involving 31 reports were included finally. Direct meta-analysis suggested that HBSS was superior to ORS, milk, saline, and water, ORS was superior to milk but inferior to coconut water and propolis, egg white was superior to milk but inferior to AVG and propolis, propolis was superior to AVG, milk, and saline, and coconut water and water was inferior to saline and milk, respectively. Network meta-analysis suggested that AVG was inferior to the other nine mediums, and propolis was superior to HBSS (SMD, −5260.24; 95% CrI, −10447.39 to −70.37) and milk (SMD, −5461.11; 95% CrI, −10574.99 to −328.51). Moreover, ranking probabilities indicated the highest probability for propolis, followed by saline, ORS, HBSS, milk, egg white, water, green tea, and AVG successively. Propolis may be the optimal media for storing avulsed teeth before replantation. However, given the availability of propolis and HBSS and the hypotonic properties of saline, ORS or milk should also be preferentially selected.

Abstract
Objective Permanent teeth trauma is most frequent in children aged 7-9 years, and the primary school teachers (PSTs) are often the first to notice it. The aim of this study was to evaluate the competence in tooth avulsion clinical issues and knowledge on dental trauma of PSTs, as they can occasionally take on the role of school nurses. Material and Methods Questionnaires were handed to 312 PSTs from 24 randomly selected primary schools in Zagreb, Croatia. An algorithm was designed for PST competence assessment. Results Response rate amounted to 81.37% (N=255). Only 3.14% (N=8) of the PSTs would replant the permanent tooth properly and only 43.92% of them (N=112) would immediately take the child to a doctor of dental medicine. Dry tissue, as a transport medium for an avulsed tooth, was chosen by 50.20% (N=128) of the respondents. Altogether, 4.71% (N=12) of PSTs were graded as competent in case of child’s tooth avulsion. Conclusion These results provided significant implications for school health, showed the educators' serious lack of knowledge in cases of dental trauma and stressed a need for continuous education of PSTs on the topic.

Abstract
Orthodontic tooth movement (OTM) has been widely observed worldwide. The OTM process is involved in several biological activities and can result in temporary hypoxia. The dynamic changes of autophagy and apoptosis during OTM have not, to the best of our knowledge, been previously reported. In the present study, an OTM animal model was established. Periodontal ligament cells (PDLCs) and osteoclasts were investigated using H&E and tartrate-resistant acid phosphatase staining. The changes in the expression levels of certain autophagy and apoptotic markers were investigated using immunohistochemical staining. A significant decrease in PDLC and an increase in osteoclast numbers were observed 1 day following OTM induction. The expression levels of Beclin-1 and LC3-II peaked at 1 h post-OTM, followed by a gradual decrease. The expression levels of P62 in each experimental group were significantly lower than those noted in the 0 h group. The expression levels of Bcl-2 were markedly increased 1 h following OTM and reached a maximum at 1 day post-OTM. The highest expression levels of Bax and caspase-3 were observed 7 days following OTM induction. The present study provided additional information regarding the involvement of autophagy and apoptotic markers in the OTM process and aided the understanding of the initiation and pathophysiological progression of this condition.

Abstract
BACKGROUND/AIM The survival of an avulsed tooth highly depends on the emergency management. The aim of this study was to evaluate the risk of ankylosis for avulsed human teeth stored in saliva preceded by various dry storage conditions prior to replantation. MATERIAL AND METHODS Data include 74 patients (54 male and 20 female) with 89 avulsed and replanted teeth (16 immature teeth, 73 mature teeth). Patient ages ranged from 6 to 36 years (median: 13.0 years). All teeth were stored in saliva before replantation. Treatment and follow-up were performed according to a standardized procedure. Follow-up periods ranged from 7 months to 20 years (mean 5.3 years). The risk of ankylosis over time was estimated by the Aalen-Johansen method in relation to the length of dry storage and the stage of root development. The effect of risk factors (root development and length of dry time) on the risk of ankylosis was analysed by Cox regression analysis. RESULTS For mature teeth, dry storage for 5 min or less before saliva storage resulted in a 47.4% (95% confidence interval (CI): 32.8-60.7) ankylosis rate. When dry storage was >5 min and <20 min, the risk of ankylosis was 76.8% (95% CI: 45.7-91.5). When dry storage exceeded 20 min prior to saliva storage, ankylosis increased to 89.3% (95% CI: 68.0-96.7). Ankylosis also increased with increasing saliva storage time. Specifically, one additional minute of wet time increased the ankylosis hazard rate (HR) by approximately 1% (CI = [0%, 2%], p = .052). Teeth with mature root development were significantly more frequently affected by ankylosis than teeth with immature root development (HR: 2.4 (95% CI: 1.0-5.5), p = .04). CONCLUSION Temporary storage in saliva should be encouraged if an avulsed permanent tooth cannot be immediately replanted or a suitable storage medium such as milk or saline is not immediately available at the place of the accident.

Abstract
Introduction: Permanent tooth avulsions (traumatic extraction; total luxation) are one ofthe most severe permanent tooth injuries and can occur as single injuries or associated with other dental injuries or injuries to the face and jaws region. They are defined as the luxation of teeth from the alveoli with complete rupture of periodontal fibres, or with one part attached to the rootcementum and the other to the alveolar bone, thus compromising the dental pulp, root cementum,and alveolar bone. The high prevalence and numerous negative consequences on the stomatognathic systems they have suggest permanent tooth avulsions should be regarded as an important public health problem. The aim: is to point out the therapeutic possibilities of permanent tooth avulsion that can ensure their longer survival in the oral cavity. Conclusion: The treatment strategy for avulsed permanent teeth is always based on limiting root canal infection and periradicular inflammation, shifting the balance from unfavourable (replacement resorption) to favourable (periodontal) healing. The success of therapy and periodontal healing depend on the duration and conditions of extraoral tooth preservation, the degree of damage to the periodontal ligament, and the condition of the pulp.

Abstract
Introduction: The aim of this study was to present the therapeutic procedure and the outcome of replantation of the avulsed permanent central maxillary incisor, found at the site of high contamination, after an extraoral period of 15 hours and dry transport. Case report: By clinical examination it was determined that the root reached the full length, with parallel edges, which corresponded to the age of the girl-8.5 years. After carefully removing the necrotic periodontal ligament from the root of the tooth, extraoral endodontic treatment was performed. The pulp was removed, the multi-sessional intracanal medicament fillings were avoided and the definitive obturation of the root canal was performed. The tooth was returned to the alveolar socket and immobilized with a wire-composite splint. After replantation, the condition of the tooth was monitored. Replacement resorption and dentoalveolar ankylosis occurred after nine months, and then cervical inflammatory resorption led to tooth loss after three and a half years. Conclusion: The achieved result can be considered as a success because during this time the replanted tooth met the developmental, functional and aesthetic requirements, which is especially important in the period of intensive growth and development of the child.

Abstract
BACKGROUND/AIMS Tooth avulsion is the most severe traumatic tooth injury. Immediate replantation after avulsion provides the highest success rate, whereas delayed replantation with dehydration for >1 h always results in ankylosis, replacement resorption, and eventual tooth loss. The aim of this study was to investigate the geomorphologic change of ultrastructure on tooth root surfaces due to dehydration. MATERIAL AND METHODS Twenty-four sound human premolars and fully developed third molars without periodontitis were selected for the experiment. Roots were separated into 6-7 pieces with an intact root surface area (3 × 3 mm2 ) and then divided into the following groups: fresh group, prolonged dehydration groups (air drying for 1, 2, 4, 12, or 24 h), and dehydrated teeth (air drying for 2 h) treated with acid (Tris-HCl buffer or citric acid buffer). More than six pieces of root from each group were subjected to scanning electron microscopy (SEM) observation. Captured images were exported to ImageJ software to quantitatively analyze the areas covered with fibers. Statistical significance was determined by comparing the means of the different groups using t-testing or one-way analysis of variance followed by post hoc testing. RESULTS Fibrous "vegetation" covering the cementum was observed on the fresh root surface by SEM. This was destroyed by dehydration (>1 h), resulting in a root surface resembling the "Gobi Desert." The difference was statistically significant (p < .001). Root surface deteriorated by dehydration could be recovered by the re-use of the fibers embedded in the cementum as acid demineralization of the outer layer of cementum exposed the embedded fibers to simulate the geomorphology of fresh root surface. CONCLUSIONS Dehydrated teeth had deteriorated geomorphology of the root surface, which could be reversed by the re-use of the fibers embedded in the cementum using citric acid. Direct evidence from SEM gives new insights into the replantation of dehydrated avulsed teeth.

Dent Traumatol 2020; 37:123-130. [PMID: 33185962 DOI: 10.1111/edt.12612] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 09/16/2020] [Accepted: 09/22/2020] [Indexed: 01/29/2023]
Abstract
BACKGROUND/AIM Success of tooth replantation depends on the quality and quantity of periodontal ligament (PDL) cells. The aims of this study were to evaluate Thai propolis extract as a storage medium for maintaining PDL cell viability and preserving gene expressions in PDL tissues. MATERIALS AND METHODS PDL cells from human premolars were tested for cytotoxicity of the extract by PrestoBlue assay to determine a non-toxic concentration. Subsequently, 96 freshly extracted premolars were allocated into different treatment groups. Control groups were freshly extracted premolars or they had been stored dry for 12 hours. Experimental avulsed teeth were created by leaving them air-dried for 30 minutes immediately after extraction, then they were immersed in Thai propolis extract, HBSS or milk for 3, 6 and 12 hours. After tooth storage, the remaining PDL cells were determined for their cell viability. RNA isolated from PDL tissues of three premolars treated similarly was analysed for periostin and S100A4 expressions using RT-qPCR. RESULTS Thai propolis extract at 0.625 mg mL-1 promoted the greatest PDL cell viability. Tooth storage in 0.625 mg mL-1 Thai propolis extract, HBSS or milk showed no difference in maintaining cell viability. Periostin mRNA level was preserved by Thai propolis extract. Expression of S100A4 mRNA in PDL tissues stored in all tested media was dampened. CONCLUSIONS PDL cells from mock avulsed teeth stored in 0.625 mg mL-1 Thai propolis extract for 3, 6 and 12 hours remained viable and the expression of periostin was preserved. This study suggests this extract as an alternative for a tooth storage medium for up to 12 hours. However, transporting an avulsed tooth in a storage medium for extended extra-oral time might affect the PDL cell phenotypes.

Abstract
Purpose The aim of this case report was to explain a multidisciplinary and conservative approach carrying out the replantation of an avulsed closed apex central incisor stored in dry conditions for a 16-hour period from the moment of trauma.
Case Report This report describes a case of a 28 year-old male who suffered contusion of the upper lip, avulsion of right upper central incisor, enamel cracks after trauma of left upper central incisor and upper left lateral incisor crown fracture due to an accident. Avulsed tooth was dry stored and it was replanted 16h after the trauma. The root was disinfected and the necrotic periodontal tissue removed, the endodontic treatment was done before replantation and a flexible splint was applied to tooth 13 to tooth 23. Two months later a contralateral tooth presented crown discoloration occurred due to pulp necrosis an endodontic treatment as well as bleaching were carried out. An esthetic restoration for lateral incisor crown fracture was also done. In the one year review the patient remains asymptomatic, with no signs of root resorption or ankylosis of the damaged teeth.
Conclusions A conservative approach of tooth with delayed reimplantation can be a stable and functional with the appropriate treatment procedures. A clinical protocol for patients and professionals for the treatment of the avulsed tooth is proposed. Key words:Endodontics, dental avulsion, avulsed tooth protocol.

Abstract
The spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in millions of confirmed cases and hundreds of thousands of deaths. Despite all efforts to contain the spread of the disease, the number of infections and deaths continue to rise, particularly in some regions. Given its presence in the salivary secretions of affected patients, and the presence of many reported asymptomatic cases that have tested positive for COVID-19, dental professionals, including Endodontists, are at high risk of becoming infected if they do not take appropriate precautions. As of today, there are no predictable treatments or approved vaccines that can protect the public and healthcare professionals from the virus; however, there is speculation that a vaccine might be available sometime in 2021. Until then, general dentists and Endodontist will need to be able to treat emergency patients in order to relieve pressure on emergency clinics in hospitals or local community hubs. In addition, as the pandemic continues, strategies to manage patients will need to evolve from a palliative to a more permanent/definitive treatment approach. In this article, an update on the treatment considerations for dental care in general is provided, as well as a discussion on the available endodontic guidelines reported in the literature. Recommendations on clinical management of endodontic emergencies are proposed.

Abstract
Avulsion is one of the most serious dental traumatic injuries with a reserved prognosis. This case report describes multiple trauma lesions in permanent central incisors of an eight-year-old girl and a four-year follow-up. The right upper incisor suffered avulsion, remained 16 h extraorally, and was replanted after extraoral endodontic therapy. The left maxillary central incisor suffered a noncomplicated crown fracture with concomitant subluxation. The present case adds to the literature a rare occurrence of success in a severe case with poor prognosis. For this reason, the International Association for Dental Traumatology (IADT) guidelines should be followed and, even in extreme situations, replantation should always be considered.

Abstract
BACKGROUND/AIMS Evidence mapping of systematic reviews (SRs) systematically and comprehensively identifies, organizes, and summarizes the distribution of scientific evidence in a field. The aims of this study were to delineate domains in dental traumatology (DT), evaluate the existing SRs within the domains, and identify the paucity of evidence for future research. METHODS Domains and sub-domains of DT were established according to the methods of qualitative research. The protocol for evidence mapping was prepared as per the guidelines of GEM and PRISMA. The search strategy was formulated using words and MeSH terms in eight databases without restriction of languages and year of publication. Gray literature, protocol registries, and references of selected articles were also searched. Duplicates were removed, and the final selection of SRs was completed. Data extraction and quality analysis using the ROBIS tool and the PRISMA checklist were performed. RESULTS The overall search resulted in 64 SRs from 1999 to 2020 with 44 published in last six years. The highest number of SRs had been performed in the Prognostic domain (n = 19) followed by the domains of Epidemiology (n = 15), Therapeutics (n = 10), Oral Biology (n = 7), Diagnostics (n = 6), Preventive (n = 5), and Research Methods (n = 2). Within each domain, there were variabilities in the number of reviewers, a priori protocols, search limitations, risk of bias methods, and meta-analysis. Of the SRs, including 4 Cochrane reviews, 28.4% were inconclusive. A low risk of bias was found in 48.4% of the SRs. Among the registered and ongoing SRs, six were from the domain of epidemiology, two in the domain of therapeutics, five from prognostics, and one each in the domains of prevention and research methods. CONCLUSION The SRs in DT could be mapped in seven domains with variabilities in the methods. The majority had an a priori registered protocol and a low risk of reporting errors. Within the Epidemiology and Preventive domains, SRs were present in all the sub-domains with the majority demonstrating low-risk of bias (ROB). The domain of prognosis had SRs in most sub-domains but with a high ROB. Insufficient numbers of SRs were present in most sub-domains of the Diagnostics, Therapeutics, Research Methods and Oral Biology domains.

Abstract
BACKGROUND/AIM An adequate storage medium can help preserve the viability of periodontal ligament cells, favoring the periodontal ligament repair process. The aim of this study was to evaluate the repair process following the delayed replantation of teeth stored in soy milk and whole milk. MATERIAL AND METHODS The maxillary right incisors of 27 rats were divided into three equally sized groups: Group SM (delayed replantation with storage in soy milk), whose teeth were immersed in 50 mL of soy milk for 60 minutes; Group WM (delayed replantation with whole milk), teeth were kept for 60 minutes in 50 mL of whole milk; and Group D (delayed replantation with dry storage), teeth were kept in dry conditions for the same period (negative control). Next, the teeth of the animals of all groups were replanted into their sockets. Systemic antibiotics were given to all the animals, and then, they were euthanized after 60 days. Sections were obtained and stained with hematoxylin and eosin for histomorphometric study. The presence and location of acute and chronic inflammatory processes in the epithelial insertion of the protective and insertion periodontium were evaluated, as well as the presence, extension, depth, and repair of root resorption, and the resorption and ankylosis with bone. Statistical differences between groups were analyzed using the Dunn test. RESULTS Groups SM and WM showed similar patterns in the repair of the periodontal ligament following delayed replantation, in relation to the inflammatory process in the proximities of the epithelial insertion, inflammation and organization of the periodontal ligament, plus root and bone resorption. However, in group WM, more ankylosis was observed than in group SM. CONCLUSION The teeth stored in soy milk and whole milk had similar periodontal repair, which shows the potential of soy milk as a storage medium before tooth replantation.

Abstract
BACKGROUND/AIM It is crucial to store an avulsed tooth appropriately to preserve the viability of the periodontal ligament cells prior to replantation. The aim of this systematic review was to identify the best available evidence for the effectiveness of any technique available to laypeople for storing an avulsed tooth compared with storage in milk or saliva. METHODS The following databases were searched (September 2019): Cochrane Library, MEDLINE, and Embase. Two reviewers independently considered trial eligibility, then extracted and analyzed data, and assessed the risk of bias. The certainty of the body of evidence was appraised according to the GRADE methodology. RESULTS Out of 4118 references, 33 studies were included and reported 23 comparisons of which 10 were synthesized in a meta-analysis. The limited evidence available favors storing an avulsed tooth in Hank's balanced salt solution (pooled SMD 2.47, 95% CI [1.59;3.34], P < .00001), propolis solution (pooled SMD 1.73, 95% CI [1.12;2.33], P < .00001), oral rehydration salts (pooled SMD 4.16, 95% CI [2.10;6.23], P < .0001), rice water, and cling film compared with storage in milk. The cell viability rate was significantly lower in teeth stored in saline solutions (pooled SMD -4.35, 95% CI [-7.55;-1.14], P = .008), tap water, buttermilk, castor oil, GC Tooth Mousse, and turmeric extract than those stored in milk. There is insufficient evidence to recommend for or against temporary storage of an avulsed tooth in saliva compared with alternative solutions. The certainty of evidence was considered low to very low due to limitations in study design, indirect study populations and outcome measures, and imprecision. CONCLUSION Although milk was shown to extend the periodontal ligament cell viability before replantation compared with saline or tap water, the following media have also demonstrated efficacy at preserving the cell viability: Hank's balanced salt solution, propolis, oral rehydration salts, rice water, and cling film.

Abstract
Science and commerce advance together and the stem cell field is no exception. With the promise of cures for conditions as diverse as cancer, autism, neural degeneration, organ replacement and addiction, long-term preservation of dental stem cells is a growth market. The discovery nearly twenty years ago, of viable, multipotent, stem cells in dental pulp from both baby and adult teeth initiated, and drives, this market.The dental stem cell preservation services, "tooth banks", focus on the collection of a child's baby teeth, as they are shed naturally, and storage of the stem cells from within the pulp for therapeutic use in later years should the child require them. This review focuses on the procedures related to these stem cell storage services and may serve as an introduction for many to the practice of "tooth banking".

Abstract
This study analyzed the efficacy of autologous platelet-rich fibrin (PRF) in maintaining and recovering cell viability of the periodontal ligament (PDL). The PDL cells were isolated from 45 extracted teeth randomly distributed among 6 groups: 5 min, 1 h, 2 h, PRF 30 min, PRF 1 h and PRF 2 h. In the groups 5 min, 1 h and 2 h (n = 5), the teeth were kept dry in extra-alveolar times of 5 min, 1 h and 2 h respectively. The teeth of the groups PRF 30 min, PRF 1 h and PRF 2 h (n = 10) were kept dry at extra-alveolar times of 30 min, 1 and 2 h followed by immersion in PRF for 45 min. PDL cells were isolated by enzymatic digestion with type II collagenase and dispase, counted and analyzed for viability with Trypan blue vital dye in Neubauer chamber. The variables total number of cells and cell viability demonstrated that in the 5 min, 1 h and 2 h groups there was a decrease after the extra-alveolar dry times of 1 and 2 h. In comparison with the total number of cells, group 1 h, considered immediate reimplantation, did not present statistical difference when compared to the groups PRF 30 min, PRF 1 h and 2 h, a result that demonstrates that PRF assists in cell maintenance and recovery. PRF provided increased cell viability in relation to the different dry extra-alveolar times analyzed (p < 0.001). Autologous PRF presented effectiveness in maintaining and recovering PDL cells from extracted teeth and kept dry for up to 2 h.

Aust Dent J 2019; 65:46-52. [PMID: 31660614 DOI: 10.1111/adj.12732] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/22/2019] [Indexed: 12/26/2022]
Abstract
BACKGROUND/AIM The aim of this study was to evaluate the knowledge of school professionals regarding the emergency management of dental avulsion. METHODS This cross-sectional study utilised a self-administered, pilot-tested questionnaire for school staff from primary schools. Descriptive statistics were used for the analysis - the prevalence and univariate associations between a categorical outcome and the variables under consideration, were evaluated using Pearson's Chi-squared test. RESULTS This survey yielded a response rate of 43.5% (n = 313). Approximately 60% of participants held valid first-aid certificates and 23% had received avulsion advice previously. Over 80% of participants expressed an unwillingness to replant an avulsed tooth, and over 90% believed that there should be greater awareness in this area. This unwillingness to replant was influenced by respondents' age (x2 = 8.13 df = 3, P = 0.043) and receiving advice previously (x2 = 13.15, df = 1, P < 0.001). Under-preparedness was related to years of experience (x2 = 15.03, df = 5, P = 0.010), first-aid training (x2 = 6.41, df = 1, P = 0.011) and receiving advice previously (x2 = 43.47, df = 1, P < 0.001). It was also evident that first-aid training positively influenced appropriate dental referral in the management pathway (x2 = 10.49, df = 1, P = 0.001). CONCLUSION This study suggests that there is an inadequate level of knowledge on the appropriate management of dental avulsion injuries amongst primary school professionals in Australia.

Abstract
Introduction: Recreational and sport activities, traffic accidents and human behaviour represent the main causes of trauma in young people. Case presentation: This report describes a case of a 15.2-year-old male who suffered uncomplicated crown fracture and avulsion of tooth 11 and uncomplicated crown fracture of tooth 21 due to a bicycle accident. Tooth 11 was dry stored and it was replanted 18 h after the trauma. The root was planed to remove the necrotic periodontal tissue, the pulp was extirpated before replantation and a flexible splint was applied to tooth 13 to tooth 23 for 3 weeks. A replacement root resorption of replanted tooth was suspected at the 3-month radiographic control and suffered a dramatic increase later; minimal infraocclusion, about 1 mm, was observed due to its ankylosis. Sixteen years after the trauma the patient was scheduled for an orthodontic and implanto-prosthetic rehabilitation. Conclusion: Delayed replantation usually has a long-term poor prognosis, so it is very important to promote awareness regarding emergency management modalities in dental traumatology especially among parents, school teachers, and coaches that are usually present at the site of the accident.

Abstract
Milk remains one of the most frequently recommended solutions for storage of avulsed teeth because it can maintain cell viability and is easily accessible. However, some negative effects of milk on avulsed teeth have been reported, just as the effects of milk on the long-term functions of cells are not clear. This study aimed to evaluate the effects of different types of milk on the viability, proliferation, and functions of periodontal ligament fibroblasts (PDLF)s in vitro. Human PDLFs were culture-medium depleted for 5 min and stored in Hanks' balanced salt solution (HBSS), whole cow's milk, low-fat cow's milk, or almond milk for 1 h at 25°C. Cell viability and proliferation were assessed using MTT assays. Expression of the genes encoding type I collagen and its modifying enzymes were analyzed using real-time PCR. Collagen matrix production was evaluated using Picrosirius red polarization. Our results showed the overall efficiency of low-fat cow's milk in maintaining the viability and proliferation of PDLFs, and in enhancing the process of collagen production. Almond milk storage resulted in the highest rate of PDLF proliferation, and comparable collagen biosynthesis ability to the control. Therefore, besides low-fat cow's milk, almond milk may potentially be an alternative tooth-storage medium for PDLF preservation and PDL tissue regeneration.

Evaluation of periodontal ligament cell viability in different storage media based on human PDL cell culture experiments-A systematic review. Dent Traumatol 2018; 34:384-393. [PMID: 30193009 DOI: 10.1111/edt.12437] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2018] [Revised: 09/02/2018] [Accepted: 09/03/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND/AIMS The best treatment for an avulsed tooth is immediate replantation. If this is not possible, a proper transport medium is required for the maintenance of viability of the periodontal ligament cells (PDL). The aim was to systematically review the efficacy of different storage media used for the survival of PDL cells of avulsed teeth in the in vitro setting. METHODS The search strategy was based on the MeSH keywords in PubMed/MEDLINE: "Transport media for avulsed teeth," "Storage media for avulsed teeth," "Knocked out teeth," "Tooth avulsion," "Biological transport of avulsed tooth," "Cell survival of avulsed tooth," "Cell viability of avulsed tooth," "Tooth replantation," and "Periodontal ligament in avulsed teeth." The "AND" and "OR" Boolean operators were applied to combine keywords. Each study was evaluated for eight criteria, including use of human PDL, in vitro cell culture models, the number of passages, types of storage media, percentages of surviving PDL cells, pH and osmolality of storage media, and the type of test used to asses PDL viability. RESULTS In 15 selected studies, nine storage media (HBSS, tap water, DMEM, milk, saliva, 10% and 20% propolis, Gatorade, and Viaspan) were analyzed at six time points. For storage up to 2 hours, HBSS, DMEM, milk, 10% propolis, 20% propolis, and Viaspan conserved more than 80% of PDL viability. For storage at 24 hours, Viaspan showed best cell survival at 88.4%, followed by DMEM (70.9%) and 10% propolis (68.3%). Milk and HBSS showed similar PDL survival at 24 hours (57.2% and 57.3%, respectively). CONCLUSIONS Milk remains the most convenient, cheapest, and readily available solution in most situations while also being capable of keeping PDL cells alive. Further studies are required to evaluate the efficacy of more commonly found storage media besides milk.
