ABSTRACT
@#Root fracture is a kind of dental trauma involving dentin, cementum, pulp tissue, periodontal membrane ligament and even the surrounding alveolar bone. It occurs frequently between the ages of 10-20, mostly in the area of the maxillary anterior teeth with high aesthetic requirements. The treatment goal for root fracture in permanent teeth is to maintain the physiological and functional integrity of the tooth as much as possible and to reduce the incidence of complications. Clinicians usually classify the affected teeth according to the position of the root fracture, including the apical, mid-root, cervical-mid-root and cervical segments, since it determines the treatment plan and the prognosis of the affected teeth. CBCT examination can avoid misdiagnosis and missed diagnosis of root fracture to the greatest extent. The sequential treatment plan of root fracture after permanent anterior tooth trauma includes initial emergency treatment, pulp vitality monitoring and complication management during follow-up. Emergency treatment mainly includes local anesthesia and repositioning, if displaced, the coronal segment of the tooth as soon as possible. Then, after checking its position radiographically, adjustment occlusion and flexible splinting for 4 weeks (4 months for cervical root fracture). The process of root fracture repair includes many tissues and is affected by many clinical factors. Timely and standardized treatment and close follow-up according to the Dental Trauma Guideline guarantee a good prognosis of root fracture. The closer the root fracture line is to the apex, the higher the survival rate is. In addition to the location of the root fracture line, the prognosis is affected by many other clinical factors, such as the displacement of the coronal fragment of the root fracture, the pathological state of the dental pulp, patient age, developmental stage of the root, timely and good replacement of the root fracture, splinting method, and the presence of other dental trauma complications. Pulp vitality should be monitored regularly, and root canal therapy of the coronal segment should be carried out only when infection of the pulp is established. This article reviews the classification, diagnosis, emergency treatment, sequential follow-up treatment, and prognostic assessment of root fracture trauma to provide suggestions for clinicians to manage root fracture trauma in permanent teeth.
ABSTRACT
A 53-year-old woman with rheumatoid arthritis had been suffering from right thumb deformity for a couple of months. Due to this, she was unable to perform the pinch movement. There were surgical options to treat the deformity, but the patient declined surgery. We therefore surmised whether we could correct the deformity with a splint. In 2012, we then proposed the use of a finger splint. The patient's finger function improved, and as of 2021, she was still using the finger splint without any problems. Thus, it is recommended to use a finger splint for thumb deformity because it is easier and less invasive than surgery.
ABSTRACT
Abstract Lateral luxation injuries are one of the most severe periodontal injuries in dental trauma. The correct diagnosis followed by repositioning of the tooth on the right position is fundamental for the periodontal ligament healing. This study reported a clinical case of lateral luxation of maxillary central incisor involving a new cone beam computed tomography (CBCT) software for reconstruction (e-Vol DX) to confirm the lateral luxation after no conclusive dental trauma injury definition by using conventional exam. The lateral luxation injury was digitally reduced by insertion of tooth back to its alveolus, and at the same session, the tooth was stabilized with a rigid splint and further changed to a semi-rigid nylon splint. During the pulpal status monitoring, the pulp was diagnosed necrotic, then the root canal was treated to prevent root resorption. External office-bleaching and restorative procedure was performed. The 4-years follow up and new imaging exam and digital reconstruction confirmed bone healing and no complication. CBCT images analyzed by eVol DX can be used to determine and to guide lateral luxation treatment.
Resumo Lesões de luxação lateral são uma das lesões periodontais mais graves no traumatismo dental. O diagnóstico seguido do reposicionamento do dente na posição correta é fundamental para o reparo do ligamento periodontal. Este estudo relata um caso clínico de luxação lateral do incisivo central superior envolvendo um novo software de reconstrução (e-Vol DX) por tomografia computadorizada de feixe cônico (TCFC) para confirmar a luxação lateral após nenhuma definição de lesão por trauma dental conclusivo pelo exame convencional. A lesão de luxação lateral foi reduzida digitalmente pela inserção do dente de volta ao seu alvéolo e, na mesma sessão, o dente foi estabilizado com uma contenção rígida e posteriormente trocada para uma contenção de nylon semirrígida. Durante o monitoramento da condição pulpar, foi diagnosticada necrose da polpa e, em seguida, o canal radicular foi tratado para evitar a reabsorção radicular. Procedimento externo de clareamento e restauração foi realizado. O acompanhamento de 4 anos e o novo exame de imagem e reconstrução digital não confirmaram reparo ósseo e nenhuma complicação. Imagens de TCFC analisadas pelo e-Vol DX podem ser utilizadas para determinar e orientar lesão de luxação lateral.

Objective@#To analyze the clinical effect of flexible fiber splint on traumatized permanent teeth with horizontal root fractures and to provide the basis for clinical treatment.@*Methods@#The case data of 54 permanent root anterior teeth with horizontal root fractures were collected. Patients with affected teeth were followed for 1 to 2 years to analyze the root fractures. The preservation rate and pulp survival rate were analyzed, and further analysis was performed on the effects of the root fracture location (cervical 1/3, Mid-root, apical 1/3), root development stage (mature permanent teeth, young permanent teeth), dislocation of the coronal fragment (<1 mm, 1 mm, > 1 mm) on root fracture healing and dental pulp survival. @*Results @# A total of 54 teeth with root fractures were treated according to the International Dental Trauma Association Treatment Guidelines. After the application of flexible fiber splint fixation, the tooth preservation rate was 90.7%, and the pulp survival rate was 75.9%, the hard tissues healing rate was 61.1%(33/54). There were no significant differences in the locations of root fractures, the developmental stages of the roots, or the degrees of dislocation of coronal fragment on the types of root fracture healing or dental pulp survival (P > 0.05). @*Conclusion@#The flexible fiber splint has a wide range of indications. Except for affected teeth with the root fracture located above the alveolar crest, other types of horizontal root fractures in anterior teeth can be treated with flexible fiber splint fixation and can achieve a good prognosis.

Background: Progressive attachment loss around the teeth because of periodontal disease can result in increased tooth mobility. This adversely affects patient's comfort, function, and esthetics. Periodontal splinting helps in accomplishing stability by redistributing the functional and parafunctional forces. There are various materials that have been used for periodontal splinting. Fiber-reinforced composite, composite resin, and metal-reinforced composite are often used as splinting materials for periodontally compromised teeth. In our study, a comparison was done among these materials for their ability to distribute the stresses at different bone levels in mobile lower incisors splinted together with canines. Materials and Methods: Five patients of age group 25–50 years with Grade 2 and 3 mobile incisors having 40% or more bone loss and firm canines with optimal bone support were selected. From the computed tomography scan of each patient, three models were developed demonstrating splinting of mandibular incisors and canines with metal-reinforced composite, fiber-reinforced composite, and composite resin. So in total, 15 models were developed and each one of them was subjected to vertical and transverse loads of 150 N. Pattern of stress distribution was observed in these models using three-dimensional finite element analysis. Results: After splinting, the stress on the canine increased when bone levels around incisors decreased while stress on incisors reduced. Conclusion: Tested splinting materials were successful in stress distribution, and metal-reinforced composite was found to be better than the other splinting materials.
ABSTRACT
PURPOSE: The purpose of this study is to compare and analyze the shear bond strength and fracture pattern in different enamel tooth surface treatments for resin splinting materials. MATERIALS AND METHODS: G-FIX and LightFix were used as tooth splinting materials. Twenty bovine mandibular incisors were used for the preparation of the specimens. The exposed enamel surface was separated into four parts. Each tooth was treated with 37% phosphoric acid, 37% phosphoric acid + adhesive resin, 37% phosphoric acid + G-premio bond, and G-premio bond for each fraction. Shear bond strength was measured using a universal testing machine. After measuring the shear bond strength, the fractured surface of the specimen was magnified with a microscope to observe the fracture pattern. Two-way ANOVA was used to verify the interaction between the material and the surface treatment method. Oneway ANOVA was used for comparison between the surface treatment methods of each material and post-hoc test was conducted with Scheffe's test. An independent t-test was conducted to compare shear bond strengths between materials in each surface treatment method. All statistics were conducted at 95% significance level. RESULTS: G-FIX, a tooth splinting resin, showed similar shear bonding strength when additional adhesive resins were used when material was applied after only acid etching, and LightFix showed the highest shear bonding strength when additional adhesive resins were used after the acid etching. In addition, both G-FIX and LightFix showed the lowest shear bond strength when only self-etching adhesive was applied without additional acid etching. Verification of interactions observed interconnection between resins and surface treatment methods. Most of the mixed failure was observed in all counties. CONCLUSION: When using G-FIX and LightFix, which are tooth-splinting materials, it is considered that sufficient adhesion will be achieved even after applying only acid etching as instructed by the manufacturer.

El autotrasplante se refiere a la transferencia quirúrgica de un dientede una posición a otra en el mismo individuo dentro de los alveolosde dientes extraídos o sitios preparados quirúrgicamente. El autotrasplante de un diente inmaduro puede ser una opción para reemplazarmolares con caries extensas en pacientes jóvenes como una alternativaal reemplazo de dientes con prótesis fi ja o implanto-soportada. Es unprocedimiento clínico con un índice de éxito de 98 por ciento cuando los dientes son trasplantados traumáticamente y el tiempo extraoral se mantiene al mínimo. El estado de desarrollo del diente determina ampliamente el potencial de reparación pulpar después del autotrasplante. Para obtener una pulpa vital en un diente autotrasplantado el foramen apical no debe medir menos de1 mm de diámetro. El área receptora debe ser 1-2 mm más grande y profunda que las medidas de las raíces donadoras parapreservar las células del ligamento periodontal, un óptimo contacto entreambas estructuras puede mejorar el suministro sanguíneo y los nivelesde nutrición de las células del ligamento periodontal, el cual puedeincrementar el éxito del autotrasplante. En este artículo se presenta un caso exitoso de autotrasplante de tercer molar inmaduro.
Autotransplantation refers to the surgical transfer of a tooth fromone position to another in the same individual onto extracted toothsockets or surgical prepared recipient sites. Autotransplantation of animmature teeth can be an option to replace extensive decayed molarsin young patients as an alternative to immediately replacing teeth withfi xed or implant-supported prosthesis. Autotransplantation is a clinicalprocedure with a success rate of 98% when teeth are transplantedatraumatically and when the extraoral time is keep to a minimum.The developmental stage of the tooth highly determines the potentialof pulpal repair after transplantation. To obtain a vital pulp in anautotransplanted tooth, the apical foramen should not be smaller than1 mm in diameter. The recipient area must be 1-2 mm larger and deeperthan the measurements of the donor roots to preserve the periodontalligament cells, an optimal contact between both structures can improvethe blood supply and the level of nutrition to the periodontal ligamentcells, which can increase the success of autotransplantation. In thispaper, we report one case of successful autotransplantation of animmature third molar.

A perda óssea, em resposta à doença periodontal, compromete a estabilidade dentária, e gera desconforto ao paciente. A contenção interdentária pode ser uma opção de tratamento definitivo, destinado principalmente à população carente. Além de possuir baixo custo, é um procedimento conservador e estético que proporciona melhor distribuição de tensão ao tecido de suporte. A paciente O. P. C., 49 anos, gênero feminino, compareceu ao Hospital Odontológico da Universidade Federal de Uberlândia, apresentando sinais clínicos de periodontite, tal como mobilidade dos incisivos centrais e laterais inferiores, inflamação e sangramento a sondagem. O reestabelecimento da saúde periodontal foi obtido através da adequação do meio bucal e o protocolo para estabilização dentária e da perda óssea foi determinado. Optou-se pela técnica de contenção intracoronária com associação de fibras de reforço impregnadas por sistema adesivo e resina composta, do dente 13 ao 23. Nessa mesma sessão, também foi proposto à reconstrução estética e fechamento de diastema empregando resina composta nos dentes anteriores inferiores. Após 13 anos de acompanhamento clínico e radiográfico verificou-se paralização e estabilização da perda óssea, reestruturação da crista óssea e redução da mobilidade dentária. Sendo assim, este relato de caso de contenção interdentária com fibra de vidro e resina composta é mais uma informação segura de que este protocolo pode ser indicado em casos de perda óssea, desde que este seja seguido rotineiramente o protocolo de boa higiene bucal e acompanhamento periódico pelo cirurgião-dentista.
Bone loss in response to periodontal disease compromises the dental stability, and causes discomfort to the patient. After basic periodontal therapy, dental splinting might be a definitive option of treatment, mainly intended for the lower class population. Besides of the low cost, it is a conservative and aesthetic procedure that also improves the stress distribution in the support tissues. The patient O. P. C., 49 years, female gender, attended the Dental Hospital of the Universidade Federal de Uberlândia, presenting clinical signs of periodontitis, such as mobility in the lower incisors, inflammation and bleeding on probing. After reestablishment of periodontal health through the adequacy of the oral cavity, the protocol to stabilize the teeth and bone loss was established. We selected the splinting technique using glass fiber-reinforced associated with composite resin extending from canine to canine. In the same session, it was proposed the esthetic reconstruction and closing diastema with composite resin in the mandibular anterior teeth. After 13-years of clinical and radiographic follow-up, it was verified the stagnation and stabilization of bone loss, restructuring of the bone crest, and reduction of mobility of teeth. Thus, this case report of interdental splint with fiberglass and composite resin is more one safety information that this protocol can be indicated in cases of bone loss, since it is routinely followed by a protocol of good oral hygiene and regular monitoring by the dentist
ABSTRACT
Objectives: The aim of this article is to shed the light on the recommendations for orthodontic movement of traumatized teeth since traumatic dental injuries forms a challenge to the orthodontists worldwide. We tried to create a kind of treatment protocol in different kinds of traumas depending on available case reports and text books in this field. Materials and Methods: Searching included dental text books and electronic searching (pubmed, medline, embase and central databases). Inclusion criteria were: Dental, oral and maxillofacial trauma oriented articles and text books. Results: 56 articles and text books met the searching criteria. Limitation: This article is basically depending on case reports. It is obvious that there is no clinical randomized studies in third field, because it depends on accidents and trauma, thus the reader will not find a discussion or a part in this article to compare between the different findings and opinions. Conclusion: Generally, minor traumatic injuries require at least three months observation period before starting orthodontic movement. When the trauma is of greater severity at least six months observation period is needed as a minimum. Teeth with horizontal root fracture should be observed for one to two years before starting orthodontic movement. More research should be done in this field. Clinical Significance: Dental traumatic injuries have a high prevalence worldwide, and it affects children, adolescents and adults. Since orthodontic tooth movement is principally a periodontal ligament phenomenon, the orthodontist should be able to deal with the periodontal ligament injuries that might happen before or during the course of orthodontic treatment.
ABSTRACT
Objective:To propose an original method of surgical treatment for the acromial extremity of the clavicle rupture (Rockwood II-VI) with modeled Kirschner wire and cortical screw. Methods:Anatomical study and a test method were applied to 43 cadavers of both sexes. During the period between 2000 and 2013, 34 patients of both sexes were operated upon using the new method. In the comparison group (n=120), the fixation of the acromial extremity of the clavicle rupture was performed with hamate plate, Lee hook and Kirschner wires. Results:Its application allows, according to the evaluation scale of Constant and Murley (1987), 10%more preservation of the function of the shoulder compared with traditional methods of surgical treatment, and shortens the required hospital treatment and temporary disability periods. Conclusions: It is shown that the proposed author’s method combines low invasiveness, minimum dimensions of the construction and low-cost treatment.
ABSTRACT
Aims: Management of vertically fractured mandibular first molar by intra coronal splinting applying the finite centre of rotation effect of Pythagorus theorem. Case Presentations: A 28 year old male patient presented at the Department of Conservative Dentistry and Endodontics with the chief complaint of pain in the lower right back region of the mouth since last the 10 days. Past dental history revealed that affected tooth had root canal treatment done two years ago. History of present illness was that pain was elicited on chewing, and applying pressure on that area, with occasional bleeding from the same region. Intraoral examination revealed that tooth 46 was tender on percussion with vertically fractured crown in mesiodistal direction. Periapical Radiograph revealed that tooth was endodontically treated, with radiolucencies at apical and furcal area, and visible fracture line in mesiodistal direction at CEJ level. Technique Used in the Study: The tooth was endodontically retreated and Pythagorus theorem was used to locate the centres of rotation on both buccal and lingual sides of tooth 46 coronally. The technique was followed by drilling a vent at the same position approximating a fibre post (3M, Relyxfibre post). The centres were different both for buccal and lingual aspects which when approximated will provide antirotation. The post was placed in the buccolingual direction and the tooth was restored with posterior composites after which the restoration was checked for any high points. Follow up of the case was done for the period of one year. Discussion: The concept of the estimation of the finite centre of rotation is like the primary objective in tightening a screw joint to generate an optimum preload that will maximize the fatigue life of the screw while offering a reasonable degree of protection against loosening. The major advantage of this approach is that the fragment was stabilized properly and there was healthy development of periodontium over the year. Conclusion: Usually the vertically fractured tooth have poor prognosis and may likely be referred for extraction if not stabilized properly. This case report emphasizes the basic concept of stabilization and preventing rotation around an axis which will give the fractured tooth a better longevity and avoid the vibrations during crown preparation. The combined effect will restore the patient’s own natural tooth back and minimizes the chances of periodontal complication.

ABSTRACT
Biosplint splinting ribbons and flowable restorative were used to stabilize the mobile anterior teeth and replace the missed teeth with in 30 patients severe periodontitis.1 and 2 years after treatment the effective ratio was 86.7% and 83.3% respectively(P >0.05), probing depth and attchment loss were decreased(P <0.05).
ABSTRACT
Spacing in dentition negatively interferes with harmony of the smile. A lot of literature has been devoted to prosthetic closure of such space(s) in the dentition; however, the only option for maintaining space(s) in tooth-supported fixed dental prosthesis (FDP) is with the aid of loop connectors. Eleven patients (seven males and four females) with mean age of 45.18 years (range 22-70 years), previously treated with porcelain fused to metal full coverage restorations joined with loop connectors, were evaluated clinically to assess the clinical status and longevity of treatment provided. All the patients were asked to fill a simple close-ended questionnaire to provide their perspective on the limitations and outcome of the treatment and rate their satisfaction level on the scale of 1-10. The cumulative survival of the FDPs with the aid of loop connectors was 90.9%. There was no reported esthetic failure and, at the time of responding to the questionnaire, none of the patients had active complaint with respect to the prosthesis and all but one of the patients were satisfied with the treatment provided. Clinical survivability and the patient feedback suggests that customized designing of loop connectors for each patient is an excellent treatment modality to successfully maintain excessive (single/generalized) spacing between teeth and effectively splint pathologically migrated and mobile teeth. The reported problems with this treatment option are all transient in nature.
ABSTRACT
Objectives: Different fiber types are available for reinforcing composite restorations. Little information exists regarding flexural strength of various fiber used to reinforce direct composites. This in vitro study examined the flexural strength of polyethylene and glass fibers when used to reinforce composite and influence of moisture exposure on the same materials. Materials and methods: The two types of fiber were used to reinforce blocks of composite (RX Flow, Dental Life Sciences) prepared to test flexural properties and compared with the unreinforced controls. Mean flexural strengths values were determined in a 3-point bend test at a crosshead speed of 8 mm/min by use of a universal testing machine. Results: Significant increases in mean flexural strength were found for all fiber-reinforced groups in comparison to the unreinforced controls at both before and after moisture exposure. The polyethylene fiber gave the greatest reinforcing effect. After 1 month of storage in an artificial saliva substitute, a significant decline occurred in the mean flexural strength of all the groups tested. Conclusion: Within the limitations of this study, the choice of fiber type was shown to have a significant increase on the flexural properties of the fiber-reinforced composite. Polyethylene fibers increased the flexural strength of the composite the most.
Objetivo: Diferentes tipos de fibras estão disponíveis para reforçar restaurações em resinas compostas. Há pouca informação sobre a resistência flexural de fibras usadas para reforçar compósitos diretos. Este estudo in vitro avaliou a resistência à flexão de fibras de polietileno e de vidro, quando usadas para reforçar resina composta e a influência da exposição à umidade sobre os mesmos materiais. Materiais e métodos: Os dois tipos de fibras foram usados para reforçar blocos de resina composta (RX Flow, Dental Life Sciences), preparados para testar as propriedades mecânicas e comparados com os controles não reforçados. Os valores médiosde flexão foram determinados em um ensaio de flexão de três pontos a uma velocidade de 8 mm/min em uma máquina de ensaio universal. Resultados: Um aumento significativo na resistência à flexão média foi encontrado para todos os grupos reforçados com fibras, em comparação com os controles não reforçadas, tanto antes quanto depois da exposição à umidade. A fibra de polietileno forneceu o maior efeito de reforço. Após 1 mês de armazenamento em saliva artificial, houve uma diminuição significativa na força média de flexão de todos os grupos testados. Conclusão: Dentro das limitações do presente estudo, o tipo de fibra demonstrou exercer um aumento significativo sobre as propriedades de flexão do compósito reforçado com fibras. Fibras de polietileno aumentaram mais a resistência à flexão do compósito.

Introduction: In patients with hopeless prognosis of the anterior teeth there is still a strong desire to save them for the sake of esthetics. If not grossly carious, broken down or discolored the extracted tooth after suitable modifications can be placed back in its original site by splinting it to the adjacent stable teeth. Materials and Methods: Fifteen patients (10 males, 5 females) in the age range of 40-65 years with pathologically migrated, unsalvageable teeth were treated by splinting the extracted teeth immediately with the stable adjacent teeth. After 12 weeks, all the patients were explained various treatment options available for replacement of the lost teeth. The patients were asked to fill out a simple closed ended questionnaire citing the various difficulties encountered during this transitional period, selection of further treatment modalities and the reasons for their choice. The feedback obtained was then analyzed statistically. Results: Hundred percent of patients were happy with the esthetics; however, 60% of them were dissatisfied with the function that it provided. The primary problem being apprehension of splint fracture and difficulty while incising and the data was found to be statistically significant (P=0.01**). All patients demanded a permanent treatment option following this with a fixed prosthesis. None of the patients were interested in the implant supported prosthesis due to cost, treatment time involved, and need for surgery. Conclusion: The concept of immediate pontic placement is surely a viable treatment option and promises an excellent transient esthetic solution for a lost tooth as well as enables good preparation of the extraction site for future prosthetic replacement.

In the past, direct stabilization and splinting of teeth using an adhesive technique required the use of wires, pins, or mesh grids. Problems with the current fiber reinforcement materials are their inherent thickness when embedded within composite resin, their availability in fixed widths and their high cost. This paper discusses the use of silane-coated industrial grade glass fibers, which can be bundled in the form of ribbon according to the required thickness and length. Of the three patients discussed in this paper, none has exhibited debonding or recurrent caries over 1-year period. By reinforcing composite splints with these industrial grade glass fibers, dentists can provide patients with restorations and splints that are economical, fracture resistant, and more durable than most alternative splinting materials of the past.

Pulpar radicular treatment and splinting of the affected tooth, technique of periodontal flap were performed. After 6 months a significant reduction of gingival rate to 0,1, deep to 3 mm at probing and dental mobility of grade I were obtained, with positive osteointegration and periodontal regeneration radiographically viewed.
ABSTRACT
PURPOSE: The aim of this study was to evaluate the effect of dimensional stability of splinting material on the accuracy of master casts. MATERIALS AND METHODS: A stainless steel metal model with 6 implants embedded was used as a master model. Implant level impressions were made after square impression copings were splinted using 5 different techniques as follows. (1) Splinted with autopolymerizing resin and sectioned, reconnected to compensate polymerization shrinkage before the impression procedure. (2) Splinted with autopolymerizing resin just before impression procedure. (3) Primary impression made with impression plaster and secondary impression were made over with polyether impression material. (4) Splinted with impression plaster. (5) Splinted with VPS bite registration material. From master model, 5 impressions and 5 experimental casts, total 25 casts were made for each of 5 splinting methods. The distortion values of each splinting methods were measured using coordinate measuring machine, capable of recordings in the x-, y-, z-axes. A one-way analysis of variance (ANOVA) at a confidence level of 95% was used to evaluate the data and Tukey's studentized range test was used to determine significant differences between the groups. RESULTS: Group 1 showed best accuracy followed by Group 3 & 4. Group 2 and 5 showed relatively larger distortion value than other groups. No significant difference was found between group 3, 4, 5 in x-axis, group 2, 3, 4 in y-axis and group 1, 3, 4, 5 in z-axis (P<.0001). CONCLUSION: Both Splinting impression copings with autopolymerizing resin following compensation of polymerization shrinkage and splinting method with impression plaster can enhance the accuracy of master cast and impression plaster can be used simple and effective splinting material for implant impression procedure.
