Long-Term Outcome of Horizontal Root Fractures in Permanent Teeth: A Retrospective Cohort Study. J Endod 2024; 50:579-589. [PMID: 38354906 DOI: 10.1016/j.joen.2024.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 02/02/2024] [Accepted: 02/03/2024] [Indexed: 02/16/2024]
Abstract
INTRODUCTION Horizontal root fracture (HRF) is a complex traumatic dental injury that affects the pulp, dentin, cementum, and periodontal ligament. This retrospective cohort study evaluated treatment outcomes in permanent teeth with HRF. METHODS We analyzed clinical and radiographic data from a dental trauma center (2006-2022). Permanent teeth with HRF with a follow up of ≥12 weeks were considered for outcome assessment (defined as clinical normalcy and radiographic healing at the fracture line). Prognostic factors were identified through multivariable logistic regression analyses (P value ≤ .05). RESULTS 125 teeth from 103 patients were included. After a median follow-up of 79 weeks, the overall favorable outcome was 92%. This includes teeth that received emergency splinting/repositioning at baseline (62.2%) and those that received subsequent endodontic intervention for the coronal fragment (baseline: 85%; subsequent follow-ups: 91.8%). Being male and incomplete root development were both significantly associated with a better outcome of splinting/repositioning (OR = 2.58; 95% CI, 1.06-6.24 and OR = 4.37; 95% CI, 1.16-16.41, respectively) and a reduced likelihood of requiring endodontic treatment (OR = 0.44; 95% CI, 0.20-0.96 and OR = 0.24; 95% CI, 0.08-0.76, respectively). Treatment delays surpassing one week were significantly associated with an increased likelihood of requiring endodontic treatment compared to timely presentations within 24 hours (OR = 3.06; 95% CI, 1.07-8.77; P value < .05). CONCLUSION With timely diagnosis and treatment, and close monitoring, HRF cases can achieve a 92% favorable outcome. Male sex and incomplete root development correlate with improved baseline outcomes and a reduced need for endodontic treatment. Conversely, delayed presentation increases the likelihood of requiring endodontic intervention.

Healing and long-term prognosis of root-fractured permanent teeth: a retrospective longitudinal study. Clin Oral Investig 2024; 28:209. [PMID: 38467867 DOI: 10.1007/s00784-024-05581-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Accepted: 02/25/2024] [Indexed: 03/13/2024]
Abstract
AIM The purpose of the present study was to evaluate permanent teeth with post-traumatic transversal root fractures, for their initial healing modality, the effect of candidate predictors and their long-term prognosis. METHODOLOGY A retrospective longitudinal clinical study was conducted to evaluate records from patients bearing transversal root fractures in permanent teeth in order to radiographically assess short-term healing and non-healing events in the fracture line, their prognostic factors and their relationship with long term outcomes. The inter-fragmentary tissues were classified as healing: hard tissue (HT), connective tissue (CT) or connective tissue and bone (CT + B) and non-healing: interposition of granulation tissue (GT). A competing risk survival analysis was conducted to estimate the hazards of healing and non-healing events in the short-term and the effect of demographic, clinical, and treatment variables was assessed using the subdistribution regression model (Fine & Gray). RESULTS Radiographic findings showed 61.4% of healing in the short-term being strongly influenced by the presence and type of concomitant injuries to the coronal fragment. Teeth with concomitant crown fractures (sHR 24.38, 95% CI [3.16-188.3], p = 0.0022), luxations with dislocations (sHR 10.58, 95% CI [1.37-81.9], p = 0.0240) and subluxations (HR 9.66, 95% CI [1.14-81.7], p = 0.0370) were more likely to present non-healing of root fractures in the short-term. The healing rate in the long-term was of 75.9%, most of them with interposition of bone and connective tissue. Kappa statistics demonstrated an overall agreement of 67.1% between short and long-term healing patterns, in special HT and CT + Bone modalities. CONCLUSION Healing at the fracture site was the most frequent outcome, both in the short-term and in the long-term. Short-term healing modality was strongly influenced by the presence and type of concomitant injuries to the crown fragment, being the worst prognosis observed in root-fractured teeth with concomitant crown fractures, followed by concomitant luxations with dislocation. CLINICAL RELEVANCE Post-traumatic transversal root fractures have a positive prognosis supporting therefore, a more conservative approach for these teeth before considering more radical treatments.

Traumatic dental injuries over an 8-year period at a German dental center: a retrospective overview and cross-sectional analysis. Int J Implant Dent 2023; 9:40. [PMID: 37910228 PMCID: PMC10620362 DOI: 10.1186/s40729-023-00506-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Accepted: 10/04/2023] [Indexed: 11/03/2023] Open
Abstract
BACKGROUND/AIM The aim of this study was to analyze a population of patients who had suffered from traumatic dental injuries (TDIs) by using different patient-, trauma- and treatment-related parameters. MATERIAL AND METHODS All dental records of patients ≥ 3 years old who had presented at the dental emergency service between Jan 1, 2009 and Dec 31, 2016 for the treatment of dental trauma were analyzed. A total of 2758 patients were invited for a recall examination at the Department for Dental Surgery and Implantology, ZZMK Carolinum, Goethe University Frankfurt, Germany; of these, 269 patients attended their recall appointments. RESULTS The enrolled patient population consisted of 1718 males and 1040 females, with a mean age of 19.63 years (median 12.00 ± 17.354 years). A total of 4909 injured teeth were assessed, with a mean of 1.78 injured teeth per patient (median 2.00 ± 1.279). Males were found to be more frequently affected by TDIs compared to females (1.65:1). The majority of these injuries occurred in the first two decades of life (66.1%; n = 1824). The majority of the patients presented for initial treatment within 24 h of their accident (95.7%). The most frequent TDIs were isolated luxation injuries 49.4% (n = 2426) and isolated crown fractures 30% (n = 1472). Combination injuries were diagnosed in 20.6% of the cases (n = 1011). CONCLUSIONS Based on the findings of the present analysis, it can be concluded that males were more frequently affected by TDIs than females. Most patients had suffered from TDI before they had turned 10 years of age. Overall, the enamel-dentin fracture was found to be the most frequent injury, followed by concussions and lateral luxations.

Clinical applications and outcomes of the surgical tooth extrusion technique: A bibliometric analysis from 1982 to 2023. J Prosthet Dent 2023:S0022-3913(23)00630-3. [PMID: 37852858 DOI: 10.1016/j.prosdent.2023.09.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 09/16/2023] [Accepted: 09/18/2023] [Indexed: 10/20/2023]
Abstract
STATEMENT OF PROBLEM The surgical extrusion technique has been advocated for severely damaged teeth as well as for intruded and unerupted teeth. However, a quantitative literature analysis is lacking. PURPOSE The purpose of this bibliometric analysis was to provide a comprehensive overview of surgical extrusion, assess the applications and outcomes, and evaluate topics for future research. MATERIAL AND METHODS An electronic search was conducted in leading databases in April 2023. Human studies with surgical tooth extrusion or synonyms in titles or abstracts were included. A bibliographic analysis, co-occurrence analysis, and coupling of publications were performed. The analysis of variance was used to assess the characteristics of the subgroups based on indications. The survival rate was evaluated by using the Kaplan-Meier method in the R software program (α=.05). RESULTS Fifty-one studies from 1982 to 2023 were included. The Journal of Dental Traumatology and the Journal of Prosthetic Dentistry combined published approximately one-third of the papers and acquired the most citations. The burst detection of keywords revealed 4 popular research topics: the Benex extraction system, chlorhexidine for infection control, rigid or semi-rigid splints to decrease the risk of complications, and novel restorative materials to improve esthetics. An overall survival rate of 96.36% was reported among 316 participants with 330 extruded teeth. No significant differences were found in study types, geographic distribution, year of publication, or citation counts among the 4 subgroups (surgical extrusion for subgingival fractures, extensive caries, intruded teeth, and unerupted teeth). A significant difference was observed among the Kaplan-Meier curves of the 4 subgroups (P=.030). CONCLUSIONS Surgical extrusion may be used to save otherwise nonrestorable teeth, and the procedure has shown promising survival rates when teeth are properly selected and the procedure is well executed. Subgingival fractures and extensive caries near bone level are the predominant indications, as well as intruded and unerupted teeth. Surgical extrusion is a reliable treatment option to facilitate tooth restoration for severely damaged teeth, especially for maxillary anterior teeth.

Abstract
Cone-beam computed tomography (CBCT) is a three-dimensional imaging modality which can aid endodontic diagnosis and treatment planning. While there are guidelines available describing the indications, there are divergent philosophies on when this technology should be applied in clinical practice. This paper reviews the applications of CBCT including the clinical relevance of parameters which can be assessed, highlights the limitations of this technology, and provides guidance on how to maximise its clinical utility.

Abstract
Repositioning a traumatized tooth involves replacing and stabilizing it. When it is not possible, a method has been developed by an acetate splint. After few weeks, the tooth was aligned and correctly positioned. Abstract Repositioning a traumatized tooth involves, first, replacing and second stabilizing it. Stabilization, on the other hand, usually requires flexible splints. Occasionally the immediate replacement may be impossible being necessary to use other procedure. When complete replacement is not possible.

Abstract
PURPOSE The purpose of this study was to gather existing data on the efficacy of tooth splinting (TS) in patients with traumatized primary teeth, evaluating their overall prognosis and reported complications. METHODS Electronic searches were performed in seven databases up to Februray/2023. Clinical studies published in the last two decades and presenting the following characteristics were included: (a) reporting on children with traumatized primary teeth; (b) describing the efficacy of splinting those teeth. Studies describing imobilization of dental avulsion were excluded. RESULTS A total of 163 potentially relevant studies were initially found. After title/abstract screening, and full-text evaluation, three retrospective studies with moderate to high risk of bias were included. The studies described the outcomes of TS in primary teeth with luxation (intrusion, extrusion, lateral displacement), intra-alveolar root fracture, and/or alveolar fracture. High clinical success rate was observed for teeth with root fracture. Benefits of spliting teeth with lateral luxation were not identified, although it may be a reccomended approach. No study was found evaluating TS for alveolar fracture. CONCLUSION Based on a low level of evidence, the findings highlight a better clinical success rate of the use of TS in the management of deciduous teeth with root fractures.

Abstract
Background/Aim Traumatic dental injuries are the result of impact injuries to the teeth and/or soft and hard tissues within and around the vicinity of the oral cavity and pose a very serious public health dilemma. The aim of this study was to appraise the level of knowledge of dentists in Australia regarding the management of traumatic dental injuries based on the International Association of Dental Traumatology (IADT) guidelines. Methodology A link to an electronic questionnaire investigating personal and professional information and twelve questions about dental trauma was distributed by email using the Qualtrics Survey Software to ensure anonymity of the respondents, to members of the Australian Dental Association. The respondents were grouped according to demographic characteristics and practice profiles. Data were evaluated by the Student’s T test or one‐way ANOVA with post hoc testing using Fisher's least significant difference, with the α level set at 5%. Results A total of 180 complete responses were obtained. The overall mean number of correct answers was 7.55 ± 1.91 from a maximum possible score of twelve. Gender, year of primary dental qualification, dentist identity (general dentist or specialist), area of main practice or region worked by the practitioner did not significantly affect the mean scores. However, increased knowledge of the IADT guidelines was significantly associated with the number of trauma cases treated and the dentists' self‐reported knowledge. Conclusions The overall knowledge of Australian dentists regarding the management of traumatic dental injuries based on the IADT guidelines was generally good but it was also deficient in some areas.

Self-revascularization following horizontal root fracture with lateral luxation injury in a permanent maxillary central incisor. JOURNAL OF PHARMACY AND BIOALLIED SCIENCES 2022; 14:S1038-S1041.

Abstract
Repair or regeneration of the pulp, following trauma, is a part of the wound healing process. However, pulp necrosis or root resorption, whether partial or complete, might obstruct this process. Because of the neurovascular bundle at the apical foramen and the periodontal ligament, the pulp in this fragment generally remains normal when the apical fragment is not moved. We describe a mature upper left central incisor with a horizontal root fracture in the mid-third of the root and lateral luxation that healed on its own after undergoing a procedure called self-revascularization. The fracture was detected during a routine dental checkup on a tooth that was asymptomatic. Two tooth pieces with trabecular bone between them were discovered using periapical radiography and cone-beam computed tomography (CBCT). Therefore, the endodontic intervention was not needed. Regular follow-up after trauma is mandatory to evaluate any signs of pulp necrosis. CBCT can help assess healing and identify resorption.

Abstract
The prognosis of traumatized teeth depends largely on the fate of the pulp and its treatment. This review aims to update the present status on the endodontic management of traumatic injuries to permanent teeth and to identify relevant research areas that could contribute to an improvement in diagnosis and treatment of traumatized permanent teeth. Future research should pay greater attention to (1) diagnostic methods to assess the perfusion of the pulp and enhance detection of tooth cracks and initial signs of root resorption; (2) improved materials for vital pulp treatment; (3) studies focusing on type and duration of splinting after root fractures; (4) antiresorptive intracanal medication in case of posttraumatic pulp necrosis and infection-related resorption and (5) long-term data on the apical barrier technique compared to revitalization.

Abstract
This case report documents the clinical approach adopted for two permanent maxillary incisors with extrusive luxation in a 16-year-old boy. The proposed procedures involved reposition of both teeth, by digital pressure and stabilized by using semi-rigid splint for 2 weeks. Endodontic therapy was performed. Clinical and radiographic follow-up examinations were conducted at 6-month intervals for two years. Assessment revealed the absence of pulpal and periapical disease and the restoration of the maxillary incisors to a state of health and normal function. A long-term clinical and radiological follow-up is needed to prevent and precociously detect possible complications that may occur following a extrusive luxation.

Abstract
Horizontal root fractures are a rare emergency in a dental office. The injury involves periodontal ligament, cementum, dentine and pulp. The healing is influenced by the location of the root fracture, the displacement of the fragments and the status of the pulp. This report presents a clinical case of horizontal fractures to both maxillary central incisors due to an act of violence. The type of occlusion has avoided a severe diastasis of the coronal parts with a subsequent damage to the pulp and periodontum. The fractures were treated with an orthodontic splint without any further therapy and hard tissue healing was observed. A careful diagnosis and well-timed treatment planning usually allow a cost-efficient and biologically-oriented therapy with a favorable outcome.

Effect of splinting times on the healing of intra-alveolar root fractures in 512 permanent teeth in humans: A Scandinavian multicenter study. Dent Traumatol 2021; 37:672-676.

Abstract
BACKGROUND/AIM Long-term splinting of teeth with intra-alveolar root fractures has been considered important for the deposition of hard tissue between the root fragments. The aim of this study was to compare the healing outcomes in teeth with intra-alveolar root fractures relative to splinting times in three dental centers in Scandinavia, using historical data. MATERIALS AND METHODS A total of 512 maxillary and mandibular incisors from three dental trauma centers were included in the study. Two of the centers used long-term splinting protocols of two to three months while the other center used a short-term splinting protocol of one month or less. Three outcomes were evaluated: (1) Healing with hard tissue (dentin and/or cementum). (2) Healing with connective tissue (periodontal ligament) interposition with or without bone between the fragments. (3) Non-healing due to the coronal pulp being necrotic and infected with granulation tissue interposed between the fragments. RESULTS The mean splinting times were 18, 81, and 110 days in the three centers. Long-term splinting resulted in hard tissue healing more frequently than short-term splinting. Short-term splinting resulted in more connective tissue/bony healing than long-term splinting, while there was no difference in the frequency of non-healing between long-term and short-term splinting protocols. CONCLUSIONS While the results suggest that long-term splinting favors hard tissue deposition, one cannot, however, conclude that long-term splinting definitely favors hard tissue healing since the treatment protocols were not randomized among the three centers. More clinical studies on the role of splinting time need to be done.

Abstract
The pulp plays a key role in the treatment of traumatic dental injuries (TDIs) and is strongly associated with the outcome, particularly in severe cases. A correct pulp diagnosis is essential as it forms the basis for developing the appropriate management strategy. However, many TDIs are complex, and their treatment requires a profound knowledge of the physiological and pathological responses of the affected tissues. This comprehensive review will look at the dentine-pulp complex and its interaction with the surrounding tissues following TDIs. The literature up to 2020 was reviewed based on several searches on PubMed and the Cochrane Library using relevant terms. In addition to the recently revised guidelines of the International Association of Dental Traumatology, this article aims to provide background information with a focus on endodontic aspects and to gather evidence on which a clinician can make decisions on the choice of the appropriate endodontic approach for traumatized permanent teeth.

Abstract
BACKGROUND The success rate of conservative endodontic management for root fracture varies greatly based on different methods used. It has been rarely reported that calcium silicate-based materials are applied in root fracture treatment.
CASE SUMMARY A 38-year-old male patient presented with spontaneous pain from the upper left anterior teeth for 1 wk. The spontaneous pain was subsequently relieved, but pain on mastication persisted for 3 d. The patient had a dental trauma from a boxing match 15 years ago. Cone beam computed tomography showed that the maxillary left central incisor had oblique fracture lines and a radiolucent lesion around the fracture line. The tooth was diagnosed with an oblique root fracture with no healing and symptomatic apical periodontitis. In the following conservative endodontic management, the coronal and apical fragments of the canal both were chemo-mechanically prepared and obturated using a single cone gutta-percha with iRoot SP (Innovative BioCreamix Inc, Vancouver, Canada), a new calcium silicate-based bioceramic root canal sealer. At follow-ups at 1, 6, 12, and 24 mo, the patient was asymptomatic and the radiolucency around the fracture line was healing radiographically.
CONCLUSION Conservative root canal treatment is an alternative treatment in some cases of oblique root fracture with no healing. The application of bioceramic sealers and single core obturation techniques may also be essential to obtain an excellent outcome.

Use of Orthodontic Methods in the Treatment of Dental Luxations: A Scoping Review. Dent J (Basel) 2021; 9:18.

Abstract
(1) Background: Treating dental luxation injuries is challenging for the clinician. Dental luxations account for 18-33% of injuries to permanent teeth and can be addressed using different therapeutic approaches. The present work was conducted with two aims: (i) to evaluate, through a scoping review, current knowledge of the orthodontic methods (repositioning and stabilization splinting) that can be used at the time of the trauma, and (ii) to investigate the frequency and type of pulp consequences arising after these traumatic injuries. (2) Methods: The literature search was conducted in the period June 2020-December 2020 using the PubMed/MEDLINE, SCOPUS and Web of Science databases. The research questions were formulated according to the PICO (Population, Intervention, Comparison, Outcomes) method and considered the following aspects: type of luxation injury and stage of root development; use of orthodontic repositioning and splinting techniques; frequency and type of pulp consequences; and compliance of treatments with international guidelines. (3) Results: The initial screening of the databases, using the selected search keywords, yielded a total of 587 articles, just 8 fully met the inclusion criteria. Closer analysis of these 8 publications revealed that they would not produce clear meta-analytical data. This made it necessary to limit the data collected to the following six items: number and type of injuries, initial therapeutic intervention, duration of follow-up, number, and type of different pulp consequences. (4) Conclusions: While orthodontic techniques are commonly used to treat dental intrusions, in the case of extrusive and lateral luxation injuries, they are less frequently used and the orthodontic approach is generally confined to the stabilization phase. Among the various possible pulp consequences, many authors consider only pulp canal obliteration (PCO) and pulp necrosis (PN), often tending to overlook physiological healing (pulp survival) and the possible development of PN after PCO. There is therefore a clear need for new, high-quality clinical studies of this topic based on systematic and standardized data collection.

Fractured alveolar process displacement evaluation-Effect of the rigidity of wire-composite splints. Dent Traumatol 2020; 37:247-255. [PMID: 33185332 DOI: 10.1111/edt.12616] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Revised: 09/08/2020] [Accepted: 09/09/2020] [Indexed: 01/01/2023]
Abstract
BACKGROUNDS/AIMS Traumatic dental injuries with bone fractures require rigid splinting. The degree of rigidity of the wire-composite splints can be challenging. The aim of this study was to evaluate the effect of the rigidity of different wire-composite splints on alveolar process displacement. MATERIAL AND METHODS A model was created using polystyrene resin to simulate the anterior maxilla, bovine incisors to simulate maxillary incisors, and polyether impression material to simulate the periodontal ligament. An alveolar process fracture was created, while maintaining the labial bone connection with the PDL. Four wire-composite splints (0.3, 0.6, 0.9, and 1.2 mm in diameter) were compared with models without splints and with no fracture (n = 5). The alveolar process displacement was measured (3 times per model/per splint type) at the fractured and adjacent central incisor regions using a deflectometer (Instron) under functional cycling and static loading (100 N). Data (μm) were analyzed using RM ANOVA, followed by Tukey's HSD test (α = 0.05). RESULTS The displacement at the region of the adjacent incisor was not influenced by the splint during static and cycling load (P > .05). The Tukey test demonstrated that the model without splints had significantly higher alveolar process displacement at the traumatized teeth than that of all other splint models (P < .001). Increasing the wire diameter from 0.3 mm to 0.9 mm significantly reduced the alveolar process displacement (P < .001). No difference was observed between the 0.9 mm (P = .123) and 1.2 mm (P = .219) wire-composite splints irrespective of the measured tooth regions. CONCLUSIONS The rigidity of the wire-composite splint significantly influenced the mobility of the fractured alveolar process. The use of at least 0.9 mm wire was effective in reducing the fractured alveolar process displacement to a level that was similar to the adjacent teeth.

Effects of different splinting times on surgically extruded teeth with a crown-root fracture: A randomized controlled trial. Dent Traumatol 2020; 37:264-274. [PMID: 33179388 DOI: 10.1111/edt.12624] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 09/09/2020] [Accepted: 09/09/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND/AIM Clinical studies evaluating the splinting time for surgically extruded teeth with crown-root fractures are lacking. The aim of this study was to compare 2-week splinting versus functional splinting times after surgical extrusion. MATERIAL AND METHODS Children aged 8-13 years who presented with crown-root fractures were included. Surgical extrusion was performed, and teeth were splinted either for 2 weeks or until normal Periotest values were achieved (functional splinting time). The outcome measures were tooth mobility, tooth loss, root resorption, marginal bone resorption and ankylosis. Measurements were taken at baseline, weekly after splint removal, and after 1, 3, 6 and 12 months. RESULTS Nineteen patients were included in the analysis. Surgically extruded teeth splinted for 2 weeks showed significantly higher mobility directly after splint removal and at 1 month after splinting compared with the functional splinting time group. The mean differences for horizontal Periotest values were 14.96 (95% confidence interval: 8.52, 21.39) and 6.63 (95% confidence interval: 0.25, 13), respectively. The vertical Periotest values were 10.47 (95% confidence interval: 1.95, 18.99) and 4.81 (95% confidence interval: -1.57, 11.18), respectively. At the 3-, 6- and 12-month follow-up intervals, there were no statistically significant differences between the groups. One tooth in the 2-week splinting group was lost. None of the teeth had ankylosis, marginal bone resorption or root resorption. CONCLUSIONS Although both groups showed neither statistical nor clinically significant differences after 12 months, there was a significant difference immediately after splint removal, with greater tooth mobility in the 2-week splinting group. Thus, a functional splinting time (4-6 weeks) can be suggested for better healing and optimal stability to allow placement of the final restoration directly after splint removal.

Abstract
BACKGROUND/AIMS Traumatic dental injuries are highly prevalent and are considered an important health problem. The aim of this study was to evaluate the in vitro stress distribution around simulated traumatized teeth subjected to different types of splints by photoelastic analysis. MATERIALS AND METHODS For each group, five models of maxillary and mandibular arches were made in photoelastic resin using prefabricated teeth models, which were fixed and adjusted in a semi-adjustable articulator. All splints were bonded with composite resin on the labial surfaces of the maxillary central incisors, the lateral incisors and the canine teeth, simulating trauma to the 11. The groups were divided according to the type of splint: control-without splint; rigid-brackets and 0.021 × 0.025 inch stainless steel wire; semi-rigid-brackets and 0.016 × 0.016 inch cobalt-chromium wire; fiber-fiberglass ribbon; and flexible-nylon thread. The groups were submitted to an occlusal force in a special device attached to a universal test machine in balanced, protrusive, and lateral occlusions. Then, the incisal edge of the 11 was ground to simulate infra-occlusion, and the tests were performed again. Five points were analyzed around tooth 11 with a polariscope, and the data were submitted to ANOVA and Tukey tests at a 5% level of significance. RESULTS When centric occlusion was analyzed by comparing normal occlusion to infra-occlusion, all groups showed high stress values in infra-occlusion with statistical differences-except for the control group. When lateral occlusion was analyzed, the nylon splint showed lower statistical differences compared with the control, fiberglass, and rigid splint groups, which did not differ between each other. The semi-rigid splint did not differ from any group. CONCLUSIONS Fiberglass and semi-rigid splints showed better stress distribution around the traumatized tooth under occlusal loads. The nylon splint showed characteristics of non-stress distribution.

Replantation of two avulsed teeth after 1 h of storage in adverse extraoral dry conditions: A thought-provoking outcome after a 15-month follow-up. Ann Anat 2020; 231:151514.

Abstract
This article reports a clinical case of an 8-year-old boy who sustained avulsion of the maxillary right central incisor and the maxillary left lateral incisor. The avulsed teeth were kept in adverse extraoral dry conditions for 1 h from the moment of trauma until their replantation. The prognosis of tooth replantation is dependent on multiple factors such as methods of teeth storage in vitro, endodontic intervention, extra-oral time, and type of retention employed. The main reasons for root resorption in this case may be the extra-oral time, the initial replantation, or the delayed endodontic treatment.

Abstract
The case that is reported here describes the replanting of a 1.1 from an ectopic position during orthodontic therapy. The 9-year-old patient suffered from class 2 type malocclusion with the upper maxilla contracted, right-left posterior cross-bite. The clinical case presented the following details: in the upper incisor group, the 1.1 was overlapping the 1.2 and was distalised and completely vestibularised, whilst in the place of the 1.1, a 1.1 supernumerary persisted in occlusion. Following several medical investigations, such as OPT and, most importantly, TC cone beam investigation, the dangerous position of the dental element became clear. This did not present vestibular cortical bone but only gingival mucosa. Following these investigations, the difficulty in bringing the dental element into its natural position through orthodontic treatment became obvious since the natural position was without sufficient bone support. From this, it became obvious that surgery and replanting of the 1.1 immediately after the extraction of the supernumerary 1.1 was the only choice available.

Abstract
BACKGROUND Root fractures are not a common injury, but a thorough understanding of their etiology, healing responses, diagnosis, management, and prognosis is essential. REVIEW The prognosis is largely related to the patient's age; degree of displacement, if any, of the coronal fragment; and the location and orientation of the fracture. The more apical the fracture is located, the better the prognosis. Teeth with root fractures located supracrestally may have the worst prognosis, but their management and outcome depend on many factors, with the most influential factor being the ability to restore the tooth because the coronal fragment usually needs to be removed. In contrast, root fractures located in the apical and middle thirds and those subcrestally in the coronal third of the root have a good prognosis and usually require little, if any, treatment apart from immediate repositioning (if the coronal fragment has been displaced) and stabilization. Monitoring of root-fractured teeth over time is essential to determine the healing response and to assess whether the pulp survives or not. In some cases, the pulp in the coronal fragment may necrose and become infected, thus requiring root canal treatment, but this should only be done to the fracture line. Pulp necrosis and infection typically occur within the first 3-4 months if it is a direct result of the trauma. However, pulp necrosis and infection can also occur many years later, in which case it is likely to be a result of bacterial penetration via cracks or breakdown of restorations. CONCLUSION Overall, root fractures should be managed conservatively unless they are located supracrestally.

Abstract
After traumatic injuries to teeth, microorganisms may invade the compromised pulp tissue and initiate pulp infection and periapical inflammation. In addition to bone resorption that typically accompanies pulp necrosis, root resorption frequently occurs. Root resorption has several variants that may occur shortly after the trauma or at a later stage. The pathological changes seen after traumatic injuries to teeth are invariably linked to the presence of microbial irritants. The presence of bacterial biofilms in the dental pulp space can be treated with regenerative or therapeutic endodontic procedures. However, necrosis of periodontal ligament is usually terminal for the tooth involved. In this review, the sources of bacteria after traumatic injuries are discussed. The types and role of microorganisms involved in the pathogenesis of endodontic pathosis after traumatic injuries are presented, and contemporary approaches for the management of these conditions are reviewed. Contemporary antimicrobial strategies are discussed. The rationale for the use of systemic and topical antimicrobials is presented. Finally, novel approaches to the use of antimicrobial therapies, particularly in regenerative procedures, are reviewed.

Abstract
Surgical extrusion should be considered as an alternative treatment in patients with structurally compromised teeth that retain coronal integrity and have favorable root anatomy. The procedure described is straightforward and can be performed quickly. A situation in which it was used to treat a maxillary premolar with substantial structural loss but well-preserved periodontal attachment is presented. The biologically oriented preparation technique is a conservative method of tooth restoration.

Abstract
BACKGROUND/AIMS The aim of this study was to evaluate the accessibility of proper and on-time treatment after dental trauma in children and to explore the affecting factors via parents' and health professionals' perspectives. The study is important to understand how to improve access to dental treatment after trauma. MATERIALS AND METHOD The method included quantitative and qualitative parts. For the quantitative method, parents of dental trauma patients who applied to Ege University, Department of Pedodontics during January 2015-June 2016 were the target group. One hundred and forty parents answered the questionnaire on trauma experiences. The participation rate was 62.78%. Questions covered variables such as first admitted health institution, time to go there, access to diagnostics, treatment methods, referral from institution, and sociodemographic characteristics of the family. On-time and proper treatment access was defined using an algorithm for treatment priority of the case, total time to reach treatment, and the correct intervention. For the qualitative method, ten parents and thirty health professionals were interviewed in-depth using a semi-structured question guide. Thematic analysis was applied to the interview texts. RESULTS The percentage of patients who accessed on-time and proper treatment was 19.29%. Logistic regression analysis showed that admission to the university clinic first increased the access to treatment by 14.135 times. For the qualitative evaluation, treatment access was summarized into three main themes: (a) physical accessibility of dental health services, (b) a quality dental health service as an outcome, and (c) communication among parties. CONCLUSION The level of accessing proper and on-time treatment was quite inadequate. It is suggested that distribution of dental care centers should be increased and dental centers where competent dentists work should be established. Performance-based payment should be reorganized and cooperation between medical and dental institutions should be encouraged.

Abstract
Traumatic dental injuries (TDIs) of permanent teeth occur frequently in children and young adults. Crown fractures and luxations are the most commonly occurring of all dental injuries. Proper diagnosis, treatment planning and followup are important for improving a favorable outcome. Guidelines should assist dentists and patients in decision making and for providing the best care effectively and efficiently. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialties were included in the group. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion of the IADT board members. The guidelines represent the best current evidence based on literature search and professional opinion. The primary goal of these guidelines is to delineate an approach for the immediate or urgent care of TDIs. In this first article, the IADT Guidelines for management of fractures and luxations of permanent teeth will be presented.

Abstract
The difficulty in providing stability to the coronal segment makes cervical root fracture one of the most challenging dental traumatic injury. This type of injury is less frequent in children. However, due to their serious consequences and poor prognosis, tooth loss may occur. This report presents the management of a case of cervical root fracture in an 11-year-old patient with epilepsy. The stabilization of the root-fractured tooth with a splint failed due to the recurrent seizures the patient had. Coronal fragment was removed and vital root submergence was performed in order to support the alveolar growth. The natural tooth crown was incorporated into a modified Nance appliance to meet the esthetic and functional requirements of the patient. After 5-year follow-up, this treatment approach has seemed to offer a long-term provisional and satisfactory solution to the consequences of a cervical root fracture injury.

Abstract
OBJECTIVE Splinting in primary dentition is limited to several traumatic dental injuries. The prognosis associated with splint use has not been fully investigated. In this study, we investigated the outcomes of traumatic injuries in primary teeth treated with splinting. MATERIALS AND METHODS We retrospectively analysed 137 children with root fractures and lateral and extrusive luxation injuries to their primary teeth who were treated with semi-rigid splints between 2010 and 2016. Treatment outcomes were analysed in patients with follow-up periods of >6 months. The outcomes of splinting were based on clinical and radiographic evaluations performed during follow-up examinations. RESULTS In total, 182 primary teeth were examined, and of these, 90 teeth were treated using semi-rigid splints. In the splint group, pathological root resorption (31.1%) was the most common complication, whereas pathological tooth loss (25.0%) was found most common in the observation group. Splinting in root fractures showed a good prognosis, whereas in lateral and extrusive luxations, it did not (p < .05). There were no relationship between treatment delay and prognosis (p > .05). CONCLUSIONS Depending on the type of luxation, splint therapy results in acceptable outcomes and may be a feasible treatment option.

Abstract
Background The aim of this study was evaluation of the cone-beam computed tomography (CBCT) image of 50 patients at the ages of 8-15 suspecting root fracture and root fracture occurred, exposed to dental traumatic. In additionally, this study was showed effect of crown fracture on root fracture healing. Material and Methods All of the individuals included in the study were obtained images with the cone-beam computed tomography range of 0,3 voxel and 8.9 seconds.(i-CAT®, Model 17-19, Imaging SciencesInternational, Hatfield, Pa USA).The information obtained from the history and CBCT images of patients were evaluated using chi-square test statistical method the mean and the distribution of the independent variables. Results 50 children, have been exposed to trauma, was detected root fracture injury in 97 teeth. Horizontal root fracture 63.9% of the 97 tooth, the oblique in 31.9%, both the horizontal and oblique in 1.03%, partial fracture in 2.06% ,and both horizontally and vertical in 1.03% was observed.The most affected teeth, respectively of, are the maxillary central incisor (41.23% left, right, 37.11%), maxillary left lateral incisor (9.27%), maxillary right lateral incisor (11.34%), and mandibular central incisor (1.03%). Conclusions Crown fractures have negative effects on spontaneous healing of root fractures. CBCT are used selected as an alternative to with conventional radiography for diagnosis of root fractures. In particular, ıt's cross-sectional image is quite useful and has been provided more conveniences seeing the results of diagnosis and treatment for clinician.

Abstract
The purpose was to describe a novel simple experimental model of injured teeth for developing dental trauma splints (DTS), and to test various splints by combining use of this model and the Periotest® device. Rubber O-rings and spring washers were used to simulate and modify injured tooth mobility. Splinting effects were assessed among three kinds of DTS, including a composite splint and two wire-composite splints (1: rectangular orthodontic wire 0.533×0.635 mm, 2: cobalt-chromium alloy wire Φ0.9 mm). The Periotest values were measured three times for each tooth before and after splint insertion. The splinting effect was defined as the change in tooth mobility. Splinting effects significantly increased in the order wire-composite splint 1<wire-composite splint 2<composite splint (p<0.05). This model system could evaluate the effects of DTS including the differences among various splint methods, which showed reasonable reproducibility of dental trauma situations depending on severity in clinical usage.

Abstract
OBJECTIVE To provide athletic trainers, health care professionals, and all those responsible for the care of athletes with clinical recommendations for preventing and managing sport-related dental and oral injuries. BACKGROUND Participation in competitive sports continues to grow at both the interscholastic and intercollegiate levels. Therefore, exposure to, and the incidence of athletic-related injury, including orofacial injury, will also likely increase. At the time of this writing, the leading governing agencies for interscholastic (National Federation of State High School Associations) and intercollegiate (National Collegiate Athletic Association) sports require only protective orofacial equipment (eg, mouthguards) for 5 and 4, respectively, of their sanctioned sports. Although orofacial injuries represent a small percentage of all sport-related injuries, the financial burden associated with these injuries (eg, tooth avulsion) can exceed $15 000 over an adult life. Therefore, effective management of sport-related dental injuries is critical to the long-term financial, physical, and emotional health of people who have experienced dental trauma. RECOMMENDATIONS Based upon the current evidence regarding sport-related orofacial injury, we provide recommendations related to planning considerations, education, and mouthguard efficacy, material, fabrication, and care considerations. Additionally, suggested best practices for managing sport-related dental injury are also given for athletic trainers and other health care professionals.

Abstract
This case series illustrates the successful orthodontic management of previously root-fractured central incisors. Orthodontic treatment was carried out to correct the underlying malocclusion, remove traumatic occlusal forces and to provide a suitable occlusion for future restorative treatment should the root-fractured teeth be lost in the future. Clinical relevance: Dental trauma occurs commonly; having affected 10% of orthodontic patients. All practitioners should be able to discuss the possibility of orthodontic treatment with patients who have had previous trauma to their front teeth.

Healing of Horizontal Intra-alveolar Root Fractures after Endodontic Treatment with Mineral Trioxide Aggregate. J Endod 2015; 42:230-5. [PMID: 26725177 DOI: 10.1016/j.joen.2015.11.016] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2015] [Revised: 11/16/2015] [Accepted: 11/18/2015] [Indexed: 12/17/2022]
Abstract
INTRODUCTION The purpose of this retrospective study was to evaluate the healing type and assess the outcome of horizontal intra-alveolar root fractures after endodontic treatment with mineral trioxide aggregate (MTA) as filling material. METHODS The clinical database of the Department of Conservative Dentistry at Yonsei University Dental Hospital, Seoul, Korea, was searched for patients with histories of intra-alveolar root fractures and endodontic treatments with MTA between October 2005 and September 2014. Radiographic healing at the fracture line was evaluated independently by 2 examiners and was classified into 4 types according to Andreasen and Hjørting-Hansen. RESULTS Of the 22 root-fractured teeth that received endodontic treatment with MTA, 19 cases participated in the follow-up after a period of at least 3 months. Seventeen of the 19 teeth (89.5%) exhibited healing of the root fractures. For each healing type, 7 teeth (36.8%) showed healing with calcified tissue, 8 teeth (42.1%) showed interposition of connective tissue, 2 teeth (10.5%) showed interposition of connective tissue and bone, and 2 teeth (10.5%) showed interposition of granulation tissue without healing. CONCLUSIONS Within the limitations of this study, intra-alveolar root fractures showed satisfactory healing outcomes after endodontic treatment with MTA. MTA could be considered to be suitable filling material for the endodontic treatment of horizontal intra-alveolar root fractures.

Abstract
In 1985 Andreasen and Andreasen published a paper on the diagnosis of luxation injuries and outlined the importance of standardized clinical, radiographic, and photographic techniques. Now 30 years later, these recommendations remain current in the International Association of Dental Traumatology (IADT) guidelines for the management of dental trauma and describe circumstances surrounding the time of injury, the extent of trauma (e.g., type of luxation injury), healing potential (e.g., stage of root development) as well as information concerning subsequent treatment. The purpose of this review was to include findings for other types of trauma and to discuss more recent studies that augment and/or improve on the original findings from 30 years ago. The present review discusses the use of a standardized clinical registration (pulpal sensibility testing, laser Doppler flowmetry, mobility testing), radiographic survey, and photographic registration of the traumatized patient. Moreover, the value of digital radiographs and recent developments in computer tomography with respect to possible enhancement of the trauma diagnosis are discussed.

Abstract
Root fractures in the middle and apical thirds of the root are treated by repositioning and for approximately 6 weeks of immobilization while those in the cervical third are immobilized for 3 months. Even though the results are good, some root-fractured teeth are lost and replaced by dental implants or fixed partial dentures. One historic but effective treatment option for those root fractures with unfavorable crown to root ratios is an endodontic implant in middle and apical third root fractures. This method offers immediate stable fixation of a crown and its coronal root segment to the underlying alveolar bone. This report documents the long-term survival of a tooth treated with an endodontic implant. A 25-year-old male patient presented following a bicycle accident with a dislocated unfavorable root fracture in the middle third. The crown with the coronal root segment was secured to the bone using a commercially available endodontic implant. The apical part of the root was removed. Although the clinical and radiological follow-up results of the endodontic implant demonstrated a good clinical function and little bone loss, the implant ultimately had to be removed after 22 years of service due to pain and increasing mobility.

Abstract
Dental trauma is an important public health problem due to high prevalence and associated limitations. The external impact accounting for trauma may result in different injury types to teeth and supporting structures. This paper describes a clinical case of tooth trauma in an 8-year-old patient exhibiting the displacement of three permanent teeth with open root apexes. Although the traumatic impact resulted in two injury types to teeth and supporting tissues (lateral luxation and alveolar bone fracture), the therapeutic approach was the same in both situations. The bone and teeth were repositioned by digital pressure, stabilized by semirigid splint, and followed up at every week. After six weeks, the splint was removed. At that moment, the clinical and radiographic findings indicated normal soft/hard tissues and absence of pulp/periodontal pathologies. At the fifth year of follow-up, the treatment success of the case was confirmed, although it has been observed that all lower incisors exhibited pulp obliteration as a consequence of the dental trauma.
