Повний текст джерелаA anquilose alvéolo-dentária é definida como a fusão da cimento e/ou dentina com o osso alveolar, provocando a perda do ligamento periodontal através da consequente substituição por tecido ósseo. A sua etiologia não está bem esclarecida, mas existem hipóteses que procuram explicar a sua origem, considerando fatores como distúrbios do metabolismo local, traumáticos e genéticos. A sua prevalência é cerca de dez vezes maior nos dentes decíduos do que nos dentes permanentes, duas vezes mais frequente na mandíbula do que na maxila, podendo ser uni ou bilateral e abranger ambos os sexos. O diagnóstico precoce é fundamental, para diminuir as suas consequências nos processos de crescimento e desenvolvimento alvéolo-dentário. Apesar do exame histológico ser o mais preciso, é o menos utlizado. O exame radiográfico apresenta limitações quando a anquilose atinge menos de 20% da superfície radicular e não se localiza por mesial ou distal das raízes. Apesar de ser através do exame clínico que esta anomalia se deteta com mais facilidade, para alguns autores, a resistência oferecida pelo dente à movimentação ortodôntica representa um único diagnóstico praticamente definitivo. O plano de tratamento depende se o dente anquilosado é decíduo ou permanente, da existência ou não de sucessores permanentes, do tempo de início da anomalia, da época do diagnóstico, do padrão de erupção e severidade da infra-oclusão, e da relação dos dentes anquilosados com os adjacentes e antagonistas. A nível da discussão foi possível averiguar que há uma grande diferença de opiniões entre autores relativamente a vários parâmetros como teorias etiológicas, prevalência e tipos de tratamento. A possibilidade de poder vir a responder, através de revisão bibliográfia, às dificuldades de diagnóstico e implicações clínicas da anquilose alvéolo-dentária, foi determinante para este trabalho. Para a sua concretização, procedeu-se a uma pesquisa manual na biblioteca da Universidade Fernando Pessoa e na biblioteca da Faculdade de Medicina Dentária da Universidade do Porto. Paralelamente, realizou-se uma pesquisa na Web através do motor de busca “Google”, e nas bases de dados “MEDLINE/Pubmed” e “BOn”. Não foi feita qualquer restrição temporal tendo-se, apenas, incluído na pesquisa livros, metanálises, artigos de revisão e artigos de descrição de casos clínicos, escritos em língua inglesa, portuguesa e espanhola. Durante a pesquisa apenas se encontraram fontes de informação de 1964 a 2014. The alveolar tooth ankylosis is defined as the fusion of cement and / or dentin with the alveolar bone, causing loss of the periodontal ligament by subsequent replacement by bone tissue. The etiology remains unclear, although there are theories that attempt to explain its origin, considering factors such as local metabolism disturbances, traumatic and genetic factors. It’s prevalence is about ten times higher in primary teeth than in permanent teeth, twice as frequent in the mandible than in the maxilla, may be unilateral or bilateral including both sexes. Early diagnosis is essential to reduce its impact on the processes of growth and alveolar dental development. Although the histological examination is the most accurate, it is the less used. Radiographic examination has restrictions when ankylosis reaches less than 20% of the root surface and is not located by mesial or distal root. Although this anomaly is more easily detected through clinical examination, some authors argue that the resistance offered by the orthodontic tooth movement is virtually a single definitive diagnosis. The treatment plan depends on whether the tooth is ankylosed deciduous or permanent, the existence of permanent successors, the start time of the anomaly, the time of diagnosis, the eruption pattern and severity of infra-occlusion, and the relationship of the teeth ankylosed with the adjacent and antagonists ones. In the discussion it was possible to verify that there is a great difference of opinions among authors with respect to several parameters such as etiological theories, prevalence and types of treatment. The possibility of being able to respond, through bibliography review to the difficulties of diagnose and clinical implications of the alveolar-dental ankylosis, was crucial to this work. For it’s realization, we proceeded to a manual search on Fernando Pessoa University library and on the College of Dental Medicine, University of Porto, library. In parallel, we performed a Web search using the search engine "Google" and a search on "MEDLINE / Pubmed" and "B-On" databases. No time restriction was done and the search has only included books, meta-analyzes, review articles, and articles describing clinical cases, written in English, Portuguese and Spanish. During the search only information sources from 1964 to 2014 were found.

Повний текст джерелаPurpose: The aim of the study was to evaluate the risk of ankylosis for avulsed human teeth stored in saliva preceded by various dry storage condition prior to replantation.Material and methods: Data from patients with replanted permanent teeth stored in saliva prior to replantation were selected from a database at Copenhagen University Hospital. Periodontal healing related to ankylosis was analyzed.Results: Seventy-four patients (54 male and 20 female) with 89 avulsed and replanted teeth, which all had been placed in saliva prior to replantation, were retrieved. The time the avulsed teeth were placed in saliva ranged from 1 to 150 minutes (mean time 35 minutes). Around 40 % of the saliva stored teeth showed healing without ankylosis. Dry storage for 5 minutes or less before saliva storage resulted in ankylosis in 40% of the teeth but when dry storage exceeded 5 minutes prior to storage in saliva, ankylosis was seen in 80%. Teeth with mature root development were significantly more often affected by ankylosis than teeth with immature root development. Ankylosis increased with increased storage time in saliva.Conclusion: Storing a tooth in saliva prior to replantation decreases the risk of ankylosis compared with dry storage. Immature teeth have a better prognosis than mature teeth. 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 are not immediately available at the place of accident.Keywords: ankylosis, replantation, saliva, storage medium, tooth avulsion.

Resumo: O objetivo deste trabalho foi analisar o reparo ósseo peri-implantar de implantes instalados sobre raízes dentárias reimplantadas tardiamente, apresentando processo de anquilose e reabsorção por substituição. Foram utilizados os terceiros e quartos pré-molares inferiores de 4 cães machos (Beagle). Os dentes foram seccionados, e as raízes mesiais extraídas e mantidas durante 1 hora em temperatura ambiente. Após a remoção do ligamento periodontal necrótico e tratamento endodôntico, imergiram-se em fluoreto de sódio por 5 minutos e reimplantou a porção no alvéolo esplintando nas porções distais. Nestas foram realizadas pulpotomia e restauração. Decorridos 30 dias, as porções mesiais tiveram suas coroas seccionadas. Após 5 meses, cinco implantes foram instalados em osso reparado, grupo I, (Controle); nove foram instalados nos alvéolos frescos pós-exodônticos das porções distais (Grupo II - Imediato) e doze implantes foram instalados sobre as raízes mesiais em processo de reabsorção radicular externa (Grupo III - experimental). Decorridos 120 dias, os resultados foram analisados pelo contato osso implante da superfície do implante sem roscas e das três primeiras roscas. Foi avaliada, também, a área de tecido ósseo presente nos espaços internos das três primeiras roscas e da área espelho correspondente. O contato osso implante foi de 55% no grupo controle, 48% no imediato e 40% no grupo experimental. A área de tecido ósseo foi, respectivamente, 71%, 61% e 55%, e a área espelho de tecido ósseo foi de 62%, 60% e 58%. Conclui-se que o reparo ósseo perimplantar de implantes instalados sobre raízes apresentou um pequeno em relação aos outros dois grupos.
Abstract: The purpose of this study was to analyze the peri-implant bone repair of dental implants placed on delayed reimplated roots, with process of ankylosis and reabsorption by substitution. The lower third and fourth pre-molar of four male dogs (Beagle) was used. The teeth were cut, and the mesial roots were extracted and kept out for 1 hour at ambient temperature. After removal of necrotic periodontal ligament and endodontic treatment, the root was immersed in sodium fluoride for 5 minutes. Then it was reimplanted in the correspondent alveolar bone and splinted in distal portion. A pulpotomy and a crown restoration were conducted on the distal portion. After 30 days, the mesial portions had their crowns cut (decoronation).Moreover, 5 months later, five implants were installed in bone repair, Group I (Control), and nine were installed in the fresh socket of the distal portions, which were extracted (Group II - Immediate). Finally, twelve implants were installed on the mesial roots, with process of external resorption (Group III - experimental). After 120 days, the results were analyzed by bone implant contact, from the surface of the implant without threads to the first three threads. It was also evaluated the area of the bone tissue located in the internal spaces of the first three threads and the corresponding mirror area. The bone implant contact was 55% in the control group, 48% in the immediate group and 40% in the experimental group. The area of bone tissue in the internal threads area was respectively 71%, 61% and 55%, and the mirror area of bone tissue had the following results: 62%, 60% and 58%. It was concluded that peri-implant bone repair of the implant put on the roots with an external resorption showed delay compared to the other two groups.

Dental ankylosis is the fusion of dental tissue (dentin and cementum) to alveolar bone without the presence of the periodontal ligament (PDL), which can progress to replacement resorption. Cone-beam computed tomography (CBCT) has been prescribed for the evaluation of unerupted teeth, and ankylosis is an important characteristic to be observed in the analysis of these teeth. The objective of this research was to establish diagnostic criteria, using pixel intensity in CBCT and associate with clinical and demographic factors. The pixel intensity value was performed by two analyzes. The first (analyze 1) evaluated the mean pixel intensity in different regions of the dento-alveolar complex in normal and ankylosis areas. The second (analyze 2) was observed the variation of pixel intensity values in two normal areas and one of ankylosis. Data were analyzed statistically by means of absolute and relative frequency measurements; odds ratio, Chi-square. The t-test was used to compare the means of pixel intensity. One hundred and fifty-seven CBCT exams of individuals with unerupeted or partially erupted teeth with suspected ankylosis were evaluated, totaling 206 teeth. Fifty-seven teeth (27.6%) had a presumptive diagnosis of ankylosis and were evaluated using pixel intensity value. In analysis 1, it was observed that the values of alveolar bone in the normal and ankylosis areas, practically have the same variability of pixel intensity value (t-test = 0.07). When comparing the density of normal PDL with the ankylosis area, a higher density is observed (t-test p <0.001). When compared to the alveolar bone interface with PDL and alveolar bone with ankylosis area, it is observed that the intensity of the pixels in the ankylosis region is greater than in the normal area (t-test p <0.001). In analysis 2, it was observed that there was a marked reduction of pixel intensity value in the PDL area, which did not occur in the ankylosis areas. Considering the clinical and demographic factors, the occurrence in individuals over 20 years old was 72.5%, and less or equal to 20 years was 27.5% (odds ratio 1.8 95% CI 0.87-3.73), and 77.2% (n = 44) were in the upper arch. The mesioangular inclination was observed in 49.1% (n = 28), and the association between impaction and dental ankylosis was not observed (p = 0.44 Chi-square). The cervical and middle thirds of root were the most affected, 38.6% and 35.1%, respectively. It was possible to observe ankylosis in 22 teeth (38.6%) in three multiplanar reconstructions. In summary, the results suggest that the CBCT examination allows the diagnosis of ankylosis and the analysis of the pixel intensity values and their variability are an important digital tool for the interpretation and diagnosis process.
Anquilose dentária constitui uma desordem, em que ocorre a fusão total ou parcial do cemento ou dentina ao osso alveolar, pela ausência do ligamento periodontal (LPD), podendo evoluir para a reabsorção por substituição. O exame de tomografia computadorizada por feixe cônico (TCFC) tem sido prescrito para a avaliação de dentes não irrompidos, sendo a anquilose uma característica importante a ser observada na análise desses dentes. O objetivo desta pesquisa foi estabelecer critérios de diagnóstico, utilizando intensidade de pixel em TCFC e associar com fatores clínicos e demográficos. A análise de intensidade de pixel foi realizada por meio de duas análises. A primeira (análise 1) avaliou a média de intensidade de pixel em diferentes regiões do complexo dento-alveolar em áreas normais e de anquilose. A segunda (análise 2) observou a variação dos valores de intensidade de pixel em duas áreas normais e uma de anquilose. Os dados foram analisados estatisticamente por meio de medidas de análise de frequência absoluta e relativa; odds ratio, Qui-quadrado. O teste-t foi utilizado para comparação das médias de intensidade de pixel. Cento e cinquenta e sete exames TCFC de indivíduos com dentes não irrompidos ou parcialmente irrompidos e com suspeita de anquilose, foram avaliados, totalizando 206 dentes. Cinquenta e sete dentes (27,6%) possuíam diagnóstico presuntivo de anquilose, e foram avaliados por meio da intensidade de pixel. Na análise 1, observou-se que os valores de osso alveolar na área normal e de anquilose, possuem praticamente a mesma variabilidade de intensidade de cinza (Teste-t p=0,07). Quando comparado a densidade do LPD normal com a área de anquilose, observa-se uma maior densidade (Teste-t p<0,001). Quando comparado a interface osso alveolar com LPD e osso alveolar com área de anquilose, observase que a intensidade dos pixels na região da anquilose é maior do que da área normal (Teste-t p<0,001). Na análise 2, observou-se que havia uma redução acentuada da intensidade de pixel na área do LPD, o que não ocorreu nas áreas de anquilose. Considerando os fatores clínicos e demográficos, a ocorrência em pacientes acima de 20 anos foi de 72,5%, e menor ou igual a 20 anos foi de 27,5% (Odds ratio 1,8 IC95% 0,87-3,73), sendo que 77,2% (n=44) foi localizada na arcada superior. A inclinação mesioangular foi observada em 49,1% (n=28), e não foi constatada a associação entre impacção e anquilose dentária (p=0,44 Quiquadrado). Os terços cervical e médio radiculares foram os mais acometidos, 38,6% e 35,1%, respectivamente. Foi possível observar anquilose em 22 dentes (38,6%), em três reconstruções multiplanares. Em síntese, os resultados sugerem que o exame de TCFC permite o diagnóstico de anquilose e a análise dos valores de pixel e sua variabilidade, constituem uma ferramenta auxiliar importante para o processo de interpretação e diagnóstico.

Повний текст джерелаThe treatment of choise for permanent dental avulsion is replantation. However, it is known that the success of the repair after replantation depend especially the extracellular and the storage medium in which is stored the tooth. Accordingly, in order to have success after replantation is necessary that the tooth is replanted immediately and/or to be kept in a medium capable of maintaining the cell´s vitality of the root surface. If that is not possible, treatment of the radicular surface should be done in order to prevent radicular resorption. Thus, the firstly aim was to perfom a systematic review to evaluate the in vivo effectiveness of different storage media for avulsed teeth. So, the second aim of this study is to test the substance as Denosumab, a monoclonal antibody, for the topical treatment of the root surface in order to prevent dental ankylosis and replacement resorption. For this, we used 36 rat incisors rights, extracted and replanted, and divided into: group I, positive control, delayed replantation without root surface treatment; groups II and III , experimental groups, delayed replantation without root surface treatmen with Denosumab 60 mg/mL and 30 mg/mL, respectively, for 10 minutes. The canals were filling with calcium hydroxide and the teeth were replanted. After periods of 15 and 60 days of the replantation, the animals will be euthanized. Then, samples are removed and processed for microscopic analysis. Histological sections were performed, stained with hematoxylin and eosin, to describe the characteristics of the dental surface and the periodontal ligament and to measure the length of ankylosis, replacement resorption and dental resorption by conventional microscopy, and for the measure the area of periodontal ligament, by fluorescence microscopy. Sequential specimens were analyzed by Brown & Brenn, for localization of bacteria; and markek by immunohistochemistryfor RANKL, OPG and Periostin (PRT). The analysis were displayed qualitatively or quantitatively. Data were subjected to statistical analysis by oneway ANOVA and the Tukey post-test and by chi-square and Fisher\'s exact tests. The significance level was set at 5%. The systematic review does not provide enough evidence to determine the best storage medium to achieve successful tooth replantation. This systematic review has identified many storage media that have been used to preserve avulsed teeth, including coconut water, tap water, soy milk, whole milk, saline solution, saliva, propolis, physiologic saline, Euro-Collins solution, HBSS, and Viaspan®. Although this review was conducted in an experimental animal model, a poor quality of the studies as well as their heterogeneity indicates that a human extrapolation should be cautious. In the experimental study in animal model, root surface treatment with Denosumab 60 mg/mL prevented ankylosis, replacement resorption, and tooth resorption, 60 days after replantation, compared with the untreated group. Brown & Brenn staining showed a lower contamination in the mineralized tissues in the Denosumab surface treatment group, regardless of the concentration used. As for immunohistochemistry, Denosumab inhibited the synthesis of RANKL without modulating OPG. Periostin was observed in periodontal ligament of tooth replanted. However, this labeling was absent in the ankylosis areas, in both experimental periods, indicating that during the ankylosis process, the periostin synthesis is inhibited, resulting in the fusion between bone and root surface.

Material: 44 skeletonized individuals with DISH from the WM Bass Donated Skeletal Collection. Methods: For each vertebra, location, extension, point of origin and appearance of vertebral outgrowths were recorded. The size of the enthesophytes at the olecranon process, patella and calcaneal tuberosity was measured with digital callipers. Results: At either end of the DISH-ankylosed segment, isolated vertical outgrowths arising from the central third of the anterior aspect of the vertebral body can usually be observed. These bone outgrowths show a well-organized external cortical layer, an internal structure of trabecular bone and usually are unaccompanied by or show minimal associated endplate degeneration. Analysis of the relationship between spinal and extra-spinal manifestations (ESM) suggests great inter-individual variability. No correlation between any ESM and the stage of spinal DISH was found. Conclusions: Small isolated outgrowths represent the earliest stages of the spinal manifestations of DISH. The use of ESM as an indicator of DISH should be undertaken with great caution until the relationship between these two features is understood. Significance: Improved accuracy of paleopathological diagnostic criteria of DISH. Limitations: Small sample comprised of only individuals with DISH. Future research: micro-CT analysis to investigate the internal structure of the spinal lesions. Analysis of extra-spinal enthesophytes in individuals with and without DISH to understand their pathogenesis and association with the spinal lesions in individuals with DISH.

Повний текст джерелаIntroduction: Temporomandibular joint (TMJ) ankylosis may be defined as the fusion of joint surfaces with bony or fibrous tissue which causes limitations on the functional activities of the oral cavity. Surgical treatment includes gap arthroplasty (GA), interpositional Arthroplasty (IA) and joint reconstruction using costochondral graft (CCG), iliac crest, clavicular, fibular, and metatarsal or alloplastic prosthesis and distraction osteogenesis. Aim and objectives: The aim of this retrospective study was to compare outcomes of GA with CCG. The objectives were to identify factors that are associated with surgical outcomes, to identify the age group that is commonly affected and to compare the mean maximum interincisal opening (MIO) in two surgical procedures. Materials and Methods: This retrospective study evaluated outcomes of 40 patients who were treated with GA and CCG between February 2007 and December 2016. The data were analysed and classified into pre-operative, intra-operative and post-operative stages. The outcomes were evaluated by calculating an achieved MIO (final MIO – preoperative MIO), and post-operative change in MIO (Op MIO - final MIO) and the final MIO, which refers to the last recorded MIO. Results: Forty patients met the criteria for this study, twenty-seven were males and thirteen were females, the age range was 2 to 55 years. Trauma was the main cause of ankylosis with (62%) (n=26), followed by congenital defects with (27.5%) (n=11) and infection with (7.5%) (n=3). The mean of the final MIO of GA and with CCG was 30 mm (SD= 7.31) and 29.47 mm (SD= 6.79) respectively. The mean of A-MIO for GA and with CCG was 22.76 mm (SD= 8.61) and 24.1 mm (SD= 7.16) respectively, while the Pop-MIO for GA and with CCG was -3.85 mm (SD= 10.11) and -2.10 mm (SD= 7.49) respectively. The results showed no statistically significant difference (P > 0.05) in the mean MIO between two groups under GA v and CCG. In addition, it showed no association between the complications, age, gender and aetiology that were investigated by using logistic regression. Conclusion: The findings of this study suggest that there is no difference in surgical outcomes between GA and IA with CCG, and the most common age groups that was affected was third stage 20-29 years (42.5%), with no association between factors and surgical outcomes.

Aim: The aim of this review was to assess clinical outcomes of autotransplanted teeth with complete root formation and the effects of various influencing factors. Materials and Methods: A systematic literature search was performed for publications to February 2013. Treatment outcomes were estimated by multilevel Poisson regression analysis. Results: Twenty-six studies were included. The estimated failure rate was 2.0% (95% confidence interval (CI) 1.2%~3.2%); estimated 1-year survival rate was 98.0% (95% CI 96.8%~98.8%); estimated 5-year survival rate was 90.5% (95% CI 84.9%~94.1%); estimated infection-related root resorption rate was 2.1% (95% CI 1.1%~4.0%); and estimated ankylosis rate was 1.2% (95% CI 0.5%~3.2%). The estimated failure rate was higher in studies without a systemic antibiotic regimen, with only suture splinting, with wire splinting for ≤ 14 days, and with posterior donor teeth. The estimated infection-related root resorption rate was higher in studies without a systemic antibiotic regimen, with endodontic treatment initiated after 14 days postoperatively, and with anterior donor teeth. The estimated ankylosis rate was higher in studies with wire splinting and anterior donor teeth. Conclusions: Results showed that outcomes and prognoses of autotransplanted teeth with complete root formation were highly predictable. Several factors seemed to influence the outcome of tooth autotransplantation.

Повний текст джерелаA anquilose da articulação temporomandibular (ATM) é uma patologia rara com diversas etiologias mas que afeta não só as características físicas e psicológicas como, também compromete a qualidade de vida do portador. O médico dentista possui um papel importante na identificação e no correto encaminhamento dos pacientes com anquilose da ATM. Assim, nesta revisão narrativa da literatura pretendeu-se abordar a classificação, fisiopatologia, epidemiologia, diagnóstico e opções de tratamento desta condição patológica. A anquilose da ATM pode ocorrer na infância ou na idade adulta, tendo repercussões diferentes ao nível craniofacial. Na criança, a anquilose da ATM pode comprometer não só a função mandibular mas também o crescimento facial. O diagnóstico atendendo às características clínicas e suportado pela realização de exames auxiliares de diagnóstico adequados, é fundamental para a decisão da abordagem terapêutica Existem diversos tratamentos e materiais que podem ser utilizados no tratamento da anquilose da ATM. A sua escolha depende dos fatores relacionados com o paciente (tipo de anquilose, idade, capacidade em suportar a colheita de material autólogo ou em receber o material aloplástico) e com o cirurgião ( experiência e escolha ), no entanto, nenhum é considerado ideal. Após a cirurgia é importante que o paciente realize os exercícios de fisioterapia adequados, melhorando os resultados obtidos em cirurgia e prevenindo a recidiva ou outras complicações pós-cirúrgicas. Muitas vezes, o médico dentista pode ser chamado à equipa de tratamento multidisciplinar com vista a minimizar a má oclusão dentária instalada.
The temporomandibular joint (TMJ) ankylosis is a rare pathology with many etiologies that affects not only physical and psychology characteristics, but also compromises the quality of life of the holder. The dentist has an important role to identify and correct the forwarding of patients with TMJ ankylosis. This narrative literature review is intended to address the classification, physiopathology, epidemiology, etiology, diagnostic and treatment options of this pathology. The TMJ ankylosis may occur during childhood or in adulthood, having different consequences on a craniofacial level. For children, TMJ ankyloses can compromise not only the jaw function but also the facial growth. The diagnostic using clinical characteristics and supported by the use of auxiliary diagnostic exams, is the key factor to decide the therapeutic approach. There are several treatments and materials which can be used for the treatment of TMJ ankylosis. The choice depends on factors related to the patient (ankyloses type, age, capacity to support harvest of autologous material or receive alloplastic material) and to the surgeon (experience and choice), however, none of them are considered optimal. After surgery it is important that the patient does physiotherapy exercises, improving the results obtained in surgery and preventing relapse or other post-surgery complications. Many times, the dentist can be associated to the multidisciplinary team in order to minimize dental malocclusion.

Повний текст джерелаThe Dental Alveolus Ankylosis is an abnormal dental tooth eruption that consists in an abnormal anatomic fusion of radicular cement with the bone tissue, without the interposition of the periodontal ligament. The treatment of the ankylosis will depend of the tooth being deciduous or permanent. There are six modalities in the treatment of permanents ankylosis teeth: not intervene; surgery removal; enhance of the dental crown with restorative material; localized osteotomy; interalveolar segmental osteotomy and orthodontic treatment. The treatment of permanents ankylosis teeth is influenced by the severity and by witch tooth is affected. Because Permanent Superior Incisors are more frequently involved in traumatic situation, they are the teeth more likely to have permanents ankylosis.

Повний текст джерелаThe temporomandibular joint (TMJ) is presented as one of the most complex and differentiated among the joints of the human body. The changes that lead to the occurrence of some joint deseases, such as TMJ ankylosis. This disease is characterized by the fusion of the mandibular condyle and skull base through fibrous tissue or bone tissue, limiting jaw movements and mouth opening, which leads to severe consequences from speech to the psychological state of the individual. Your rating will vary with the severity of the case and among the most common etiologic factors, trauma and infections present themselves as pioneers for this condition. Because it is asymptomatic and due to anatomical TMJ, in addition to clinical examination, imaging tests are used for more accurate diagnosis and decision making. There are a variety of techniques and many controversies regarding the standard method for the treatment of this pathology, and there is therefore a consensus among researchers, and, through this work, we can highlight the many researches that have been done on the subject. However, regardless of the technique being used, the main purpose is to treat the release of the jaw and restore functionality. For post-operative physical therapy is an important factor for minimizing some consequences and prevention reanquilose. Given the above, through a literature review, the objective of this research is to analyze and describe the concepts and experiences reported by several researchers about the processes involving the TMJ ankylosis, including some anatomic considerations, causes, characteristics, diagnosis and treatment as well as other information relevant to the subject.

Повний текст джерелаEpidemiological studies have shown that trauma cover 10-35% of the population. Tooth avulsion is approximately 0.5-3% of traumatic injuries in the permanent dentition, occurring more frequently in patients from 7 to 11 years. Among injuries, tooth avulsion is considered one of the most serious types, because consist in the total displacement or avulsion of the tooth out of its socket, causing disruption of the gingival epithelium, damage to the pulp and periodontal ligament. It is necessary to know when, how and where was the traumatic accident. A good assessment of the patient's complaints; the conducting of intraoral; extra oral and radiographic examinations help the dentist in the development of a correct diagnosis and therefore a good prognosis. Different types of aqueous storage have been investigated as the best way to preserve the L.P cells of avulsed teeth and consequently a better prognosis. Many solutions have been proposed and / or tested as a storage medium for avulsed teeth example: Hank's Balanced Salt Solution (HBSS); Viaspan®; tap water, saliva, bovine milk, propolis, saline solution and contact lenses solution. In order to combat or minimize problems as and ankylosis, external inflammatory root resorption or early tooth loss, it has become important to the medical community to develop protocols and preventive measures for teeth with complete and incomplete root formation that have suffered trauma avulsion. The methodology that was used in this dissertation was bibliographical, using scientific articles and books and related to the topic.
