THE AIM OF THE STUDY: Was to assess the efficacy and timing of emergency dental care in children with permanent teeth trauma according to analysis of medical records in an emergency unit of a municipal dental clinic. MATERIAL AND METHODS: The study involved 320 medical records of pediatric patients admitted to emergency dental care unit of a municipal dental clinic in 2021 because of maxillofacial trauma from which 221 records of children with acute dental trauma were extracted. The quality of documentation of the medical records, rationale for diagnosis and adequacy of emergency dental treatment were analyzed. RESULTS: No records included diagnosis code according to ICD-10. Trauma history was described in the majority of records by in 67% of them no trauma time was stated with proper precision. In 67.6% of permanent teeth trauma cases emergency aid was carried out inadequately. All patients with uncomplicated crown fractures were dismissed with no treatment. In complicated crown fractures needing pulp vitality preservation the pulp was devitalized or just anesthetized. Tooth replantation in avulsion cases was not performed. In 13.5% of records the treatment was not properly described. In 67.6% of records there were no recommendations for follow-ups. CONCLUSION: There is a strong need for the improvement of knowledge of traumatic dental injuries management among Russian pediatric dentists by elaboration and implementation of protocols for dental traumas treatment.

Incidence, characteristics and cost of head, neck and dental injuries in non-professional football (soccer) using 3 years of sports injury insurance data.

AIM: This descriptive epidemiological study aimed to quantify the incidence, characteristics and costs of head, neck and dental injuries in non-professional football players. METHODS: Injury data were coded (using Orchard Sports Injury and Illness Classification System) from a de-identified insurance database containing three seasons (2018-2020) of data. Cost data included direct and indirect costs presented by type of injury, age group and sex using means ± SD, range of costs ($AU) and total costs ± SE. Chi-squared tests were used to analyse the data (significance level p < .05) with injury incidence rates (IR) calculated per 1000 match hours and per 1000 injury insurance claims. RESULTS: A total of 388 injuries affecting 240 players were sustained. Of these, 43% (n = 102) of players also sustained one or more secondary injuries, mainly to the head or neck area. Dental injuries (n = 143, 39%, IR = 0.008) accounted for the highest number of primary and secondary injuries and the highest mean direct cost per injury ($AU1152), while head and facial injuries accounted for the highest proportion of total costs ($AU434,101). Players who sustained one or more secondary injuries had the highest direct and indirect mean cost per injury. CONCLUSIONS: Given the frequency and cost of dental injuries in non-professional football players, injury prevention initiatives warrant further investigation.

Evaluation of primary teeth affected by dental trauma in patients visiting a university clinic, part 2: dental injury types, treatment strategies, and complications.

OBJECTIVES: This article focuses on treatments and complications in patients presenting dental trauma in primary teeth. Treatment alternatives begin with the decision of performing a procedure under clinical settings or pharmacological techniques (PC) in young children. Correct diagnosis and treatment are crucial to maximize the chances of a favorable outcome. MATERIALS AND METHODS: The files of 320 patients aged 0-9 years who presented to the Erciyes University Faculty of Dentistry Department for dental trauma management in primary teeth were evaluated in between 2018 and 2021 for 3-year period. The following information were extracted from patients' records: injury type, affected teeth, caries condition of the teeth, treatment preferences of the dentists. Additionally postoperative complications and their management were evaluated. RESULTS: While 63.1% of the traumatized teeth were caries-free, 35.8% of the teeth had caries. The most frequent dental injuries was simple crown fractures (42.9%), followed by complicated crown fractures (38.5%). Treatments were mostly done in clinical conditions (67.9%) and mostly patients attend regularly to follow-up visits (85.6%). Clinicians prefer more radical treatments under sedation or GA (92.4% extraction of injured tooth). Coronal discoloration was the most common complication, and 35.3% had pulp necrosis for longer term results. CONCLUSION: Follow-up decisions made after concussion in the primary teeth might be appropriate for the patient. Examination of the complication status of primary teeth with simple crown fracture injury revealed that 59.5% of patients did not have any complications. Follow-up decisions were found to be appropriate for crowns with coloration alone. CLINICAL RELEVANCE: All options should be considered to provide the best care for children after primary tooth trauma; this can be achieved by being informed about the treatment and its consequences, and if necessary, a positive prognosis can be achieved with an interdisciplinary approach.

Aspectos clínicos y forenses del color rosa de los dientes: reporte de un caso / Clinical and forensic aspects of the pink color of teeth: report of a case

La coloración rosa de los dientes puede originarse por diferentes factores. En el ámbito forense se ha descrito al fenómeno denominado post mortem pink teeth como un signo asociado a muertes violentas de etiología diversa. En la práctica clínica también es posible observar pacientes con dientes rosados, fre-cuentemente ocasionados por traumatismos o iatro-genia proveniente de ortodoncia, cuyo mecanismo de producción obedece a distintas etiopatogenias, destacándose las reabsorciones dentinarias inter-nas, cemento-dentinarias externas y calcificaciones dentinarias. El presente artículo expone el caso de un individuo adulto con antecedente de trauma óseo-dentario por accidente vial que, luego de un prolon-gado tiempo, asiste al Servicio de Urgencias Odon-tológicas y Orientación de Pacientes de la Facultad de Odontología de la Universidad de Buenos Aires, en donde se le detecta, a modo de hallazgo exploratorio, una ostensible coloración rosada en el canino infe-rior derecho. La situación motivó un pormenorizado abordaje clínico y radiográfico, indagando respecto a los probables factores que intervinieron en su ge-neración y desarrollo (AU)

The pink coloration of the teeth can be caused by dif-ferent factors. In the forensic field, the phenomenon called post mortem pink teeth has been described as a sign associated with violent deaths of various etiology. In clinical practice, it is also possible to ob-serve patients with pink teeth, frequently caused by trauma or iatrogenesis from orthodontics, whose production mechanism is due to different etiopatho-genesis, highlighting internal dentin resorption, ex-ternal cemento-dentinal resorption and dentin calci-fications. This article presents the case of an adult individual with a history of bone-dental trauma due to a road accident who, after a long time, attends the Dental Emergency and Patient Guidance Service of the Faculty of Dentistry of the University of Bue-nos Aires, where an ostensible pink coloration was detected in the lower right canine as an exploratory finding. The situation motivated a detailed clinical and radiographic approach, inquiring about the probable factors that intervened in its generation and development (AU)

Does primary trauma lead to developmental defects in permanent teeth?

Introduction A systematic review of existing evidence to determine if trauma in the primary dentition causes alteration in the development of the underlying permanent dentition.Data sources Six electronic databases (PubMed, Medline, MEDES, Scopus, Lilacs and Embase) were used to search a range of dental terms relating to dental trauma to locate studies between 1972-2020.Study selection Study selection was carried out by two authors by reviewing title, abstract and then full articles. A third author was consulted if consensus for inclusion was needed. Eligibility criteria included all scientific articles concerning sequalae to the human permanent dentition following trauma to the primary dentition. Only English, German and Spanish languages were included. For evaluation, the studies must have satisfied the following: a) minimum sample of 50 children to be representative; b) radiographic examination; and c) appropriate follow-up period up to permanent successor eruption.From 537 studies, 18 studies were identified for consideration in the review, comprising of 13 cross-sectional studies, two cohort studies and three case control studies.Data extraction and synthesis The Newcastle-Ottawa Scale was used to extract data and determine study quality. Only studies determined as high quality were included in the review. Four cross-sectional studies and three case control studies, totalling seven studies, were used. Data from these high-quality studies was summarised into table format.Results Large variation in study sample size existed from 138-753 traumatised teeth and 78-879 children. Both sexes were included in all studies and the children were aged between 0-17 years.Some studies found there was no difference in rate of trauma between girls and boys, while others found there was a higher incidence of trauma in boys than girls. The most frequently traumatised teeth were the upper primary central incisors. Whilst most studies covered all types of primary trauma, two only studied intrusion and one specified the type of primary trauma as luxation or fracture injuries.Whilst some of the studies concluded a higher frequency of defects to permanent teeth following primary intrusion trauma aged four and under, others showed no significant differences between the age of intrusion and the effect to the successor incisor.Enamel defects of the permanent teeth were the most common sequalae with a wide prevalence reported between 4.5-68.8%. Enamel defects were classified as hypoplasia and hypocalcification. Ectopic or altered eruption, crown or root dilacerations and odontoma development were observed less often, with the latter very rarely.Conclusions Primary tooth intrusion trauma causes the highest proportion of sequalae presenting as enamel defects. Younger patients experiencing primary trauma are more likely to obtain damage to the succeeding dentition. The existing quality of evidence is limited due to the observational nature of the studies available.

Prevalence of sequelae after traumatic dental injuries to anterior primary teeth: A systematic review and meta-analysis.

BACKGROUND/AIM: Clinical and radiographic sequelae are common following traumatic dental injuries to primary teeth. The aim of this systematic review was to assess the prevalence of such sequelae. MATERIALS AND METHODS: Searches were conducted in the PubMed, Scopus, Embase, Web of Science, and BBO/LILACS databases as well as the gray literature. The outcome of interest was the prevalence of the most common sequelae following traumatic dental injuries to anterior primary teeth. Observational studies that evaluated such sequelae were included. Data were extracted, and methodological quality was appraised using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data. The number of sequelae per tooth and the total number of teeth evaluated in each study were considered to calculate pooled prevalence rates with 95% confidence intervals (CI). The quality of the evidence was determined using the GRADE approach. RESULTS: Twenty-five articles were included in this systematic review and meta-analysis. The prevalence of each complication in descending order was as follows: 39.7% crown discoloration (95% CI: 29.52-50.32), 24.3% pulp necrosis with infection (95% CI: 17.34-32.06), 16.2% periapical radiolucency (95% CI: 8.88-25.49), 15.9% premature tooth loss (95% CI: 9.93-23.15), 14.8% pulp canal obliteration (95% CI: 8.46-22.73), 11.9% pathological root resorption (95% CI: 7.68-16.98), 7.1% abscess/fistula (95% CI: 4.4-10.6), and 1.8% ankylosis (95% CI: 0.82-3.17). The certainty of the evidence was very low. CONCLUSIONS: Crown discoloration was the most common sequela in injured primary teeth, but this should be interpreted with caution due to the very low certainty of the evidence. Considerable variation was found in the prevalence of each sequela.

Traumatic dental injuries and their sequelae in visually impaired adolescents.

BACKGROUND/AIM: Traumatic dental injuries are a public health problem. Visual impairment can be considered a risk factor for traumatic dental injury given the difficulties imposed upon visually impaired patients by limited physical perception. The aim of this study was to evaluate the frequency of traumatic dental injuries and their sequelae in adolescents with visual impairment. MATERIAL AND METHODS: Adolescents (12-18 years) with visual impairment (blind or low vision) and no other special needs were included in the study. Data were collected after a clinical and radiographic examination. Data regarding gender, age, type of visual impairment, site of traumatic dental injury, tooth type, and affected tissues, care, and sequelae were obtained. The data were analyzed descriptively and with the chi-square test (p < .05). RESULTS: Among 96 adolescents (65% blind; 55% female), 20.8% (n = 20) reported they had previously experienced a traumatic dental injury of 33 teeth (78.8% maxillary central incisors). Combined injuries (30.3%; n = 10) were the most common traumatic dental injuries, followed by concussion (27.3%, n = 9) and enamel-dentine fractures (21.2%, n = 7). Sequelae were observed in 27.3% (n = 9) of the teeth affected by a traumatic dental injury, and apical periodontitis (77.8%, n = 7) was the most common. CONCLUSION: The frequency of traumatic dental injuries among visually impaired adolescents can be considered high, and the observed sequelae could have been minimized if adequate clinical and radiographic follow up had been carried out. These results suggest the importance of enhanced educational efforts to reduce traumatic dental injuries.

Developmental Dental Defects in Permanent Teeth Resulting from Trauma in Primary Dentition: A Systematic Review.

The objective was to determine whether trauma in primary dentition causes alterations in the development of permanent dentition. Searches were made in May 2020 using PubMed, MEDLINE, MEDES, Scopus, Lilacs, and Embase. Papers in English, German, and Spanish, without restrictions in the year of publication, were included. The quality of the studies was analyzed using the NOS Scale. The search retrieved 537 references, and seven studies were included for a qualitative analysis. The results showed that trauma to a deciduous tooth can damage the bud of the permanent tooth. Enamel discoloration and/or hypoplasia were the most common sequelae in the permanent teeth after trauma to the primary predecessor. The type and severity of sequelae in the permanent tooth are associated with the development phase of the bud. Children with trauma of their primary teeth should receive checkups until the eruption of the permanent teeth for the early diagnosis and treatment of possible sequelae. Intrusion of the primary tooth was the trauma that caused the most damage and enamel alterations the most frequent sequelae.

Impact of untreated dental caries and dental pain on sadness related to oral health of Brazilian children.

PURPOSE: Children should feel sad when they believe that a negative outcome is permanent. The sadness that an oral problem might bring tends to contribute to children's loneliness and increase the social stress levels. The aim of this study was to evaluate the impact of untreated dental caries, dental pain, malocclusion, and traumatic dental injury on prevalence of sadness related to oral health among Brazilian children. METHODS: This cross-sectional study was carried out with 397 children aged 8-10 years randomly selected from public and private schools in Diamantina, Brazil. The Brazilian version of the CPQ8-10 was applied. Sadness was collected through the question, "In the last month how often did you feel sad because of your teeth or mouth?" and dental pain through the question, "In the last month, how many times have you had pain in your teeth?" One calibrated examiner (Kappa value intra examiner: 0.77-0.91; Kappa value inter examiner: 0.80-1.00) performed the exam for dental caries (DMFT), malocclusion (DAI), and dental trauma (O'Brien). Parents answered questions addressing socioeconomic issues. Descriptive analyses, Chi-square test, and hierarchical Poisson regression models were performed (IC 95%; p < 0.05)." RESULTS: The prevalence of sadness related to oral health was 30.5% (n = 121). Sadness related to oral health was associated with untreated dental caries (PR: 1.46; 95% CI 1.32-2.46; p = 0.001 ) and dental pain (PR: 2.91; 95% CI 2.00-4.22; p < 0.001). Other clinical variables analyzed (traumatic dental injury and malocclusion) were not significantly associated with sadness related to oral health. CONCLUSIONS: Children with untreated dental caries and dental pain presented a higher report of sadness related to oral health.

Marsupialização de cisto dentígero após traumatismo / Marsupialization of dentigerous cyst after traumatism

Objetivo: as causas mais comuns das alterações na dentição permanente são os traumatismos alvéolo-dentários (TAD) na dentição decídua, ultrapassando, inclusive, as incidências de cárie ou doença periodontal. Estes podem levar a hipoplasia de esmalte, alterações na morfologia dentária e desenvolvimento de cistos, como o cisto dentígero, considerando ainda que o tratamento desta ocorrência diverge ao tratar da dentição decídua e não da permanente. O objetivo deste trabalho é ilustrar essas características e como elas podem ser manejadas através de um relato de caso. Relato de caso: no caso em questão, ocorreu o desenvolvimento de um cisto dentígero de grandes dimensões após traumatismo alvéolo-dentário em dentição decídua na região anterior da maxila com retenção de três dentes permanentes. Foram discutidas as formas terapêuticas para tal situação clínica, bem como a possibilidade de uma abordagem multidisciplinar da cirurgia-ortodontia. Considerações finais: os TADs na dentição decídua devem ser bem diagnosticados e tratados, visando a prevenção de sequelas na dentição permanente.(AU)

Objective: the most common causes of changes in permanent dentition are alveolar-dental trauma (TAD) in deciduous dentition, with occurrence rates even higher than decays or periodontal disease, which can lead to enamel hypoplasia, changes in dental morphology and the development of cysts such as the dentigerous cyst, considering treatment differs when dealing with deciduous dentition instead of permanent dentition. The objective of this work is to illustrate these characteristics and propose a possible treatment, through a case report. Case report: in the case at hand occurred a development of a large dentigerous cyst occurred after TAD in primary dentition, in the anterior region of the maxilla with retention of three permanent teeth, discussing the therapeutic forms for such clinical situation, as well as the possibility of a multidisciplinary approach to surgery-orthodontics. Final considerations: TAD in deciduous teeth should be well diagnosed and treated aiming to prevent sequelae in permanent dentition.(AU)

Treatment of severely decayed anterior primary teeth with short-post technique (Mushroom Restorations) under general anesthesia.

AIMS: The aim of this study was to evaluation the treatment success of the short post technique (mushroom restoration) using a composite resin in severely decayed primary anterior teeth after 6, 12, and 18 months after treatment. METHODS: Eighteen children aged 3-5 years with severely decayed primary maxillary anterior teeth (60 anterior maxillary primary teeth in total) were included. Patients were treated under general anesthesia (GA). After pulpectomy, a "mushroom shape" was formed in the root canals for the purpose of retention, and the root canals were filled with zinc oxide-eugenol (ZOE), and the teeth were restored with composite resin. The status of treatment was evaluated clinically and radiographically for periapical radiolucency, pathological root resorption, marginal fracture, and loss of restoration for each treated tooth. All findings were recorded. RESULTS: As a result of the evaluation criteria, the success rates at 6, 12 and 18 months were 86%, 80%, and 71%, respectively. None of the teeth showed apical radiolucency or pathological root resorption at the end of the 18th month period. CONCLUSION: The short-post (mushroom restorations) technique is a clinically acceptable alternative method for restoration of severely decayed primary teeth. This study supports the feasibility of treatment with this technique for pediatric patients treated under GA.

Dental trauma with intrusive luxation and six-year monitoring: clinical case report / Traumatismo dentário com luxação intrusiva com acompanhamento de seis anos: relato de caso clínico

Objective: this study is designed to report a clinical intrusion case, which exhibited enamel hypoplasia on the crown of tooth 11 and which underwent clinical and X-ray monitoring for six years. Case report: A threeyear- old female patient exhibited intrusion of deciduous teeth 51, 52, 61, and 62. After X-ray, it was detected that teeth 51 and 61 had perforated the nasal cavity floor, but all four teeth had re-erupted and began to be monitored. After six months, teeth 51 and 61 exhibited bone loss in the interproximal area, as well as mobility, which led to tooth extraction. Teeth 52 and 62 re-erupted in a satisfactory position, and exhibited no signs and symptoms of infection, periapical alteration, or mobility. These teeth were therefore maintained in the arch. After six years, it was detected that tooth 11 had erupted with enamel hypoplasia. Final considerations: Longterm clinical and X-ray control proved essential, as it allowed for the early diagnosis of potential alterations, and minimized potential sequelae to the permanent teeth.(AU)

Objetivo: relatar um caso clínico de intrusão com acompanhamento clínico e radiográfico de 6 anos, que apresentou hipoplasia de esmalte na coroa do dente 11. Relato de caso: paciente de 3 anos, sexo feminino, apresentou intrusão dos dentes decíduos 51, 52, 61 e 62. Após radiografia, foi detectado que os dentes 51 e 61 tinham perfurado o soalho da fossa nasal, porém, ocorreu re-erupção dos 4 dentes e foi realizado acompanhamento. Após 6 meses, nos dentes 51 e 61, foram observadas perda óssea na região interproximal e mobilidade, optando-se pelas exodontias. Os dentes 52 e 62 re-erupcionaram em posição satisfatória e com ausência de sinais e sintomas de infecções, alterações periapicais e mobilidade, sendo mantidos no arco. Após 6 anos, foi observado que o dente 11 erupcionou apresentando hipoplasia de esmalte. Considerações finais: mostrou-se essencial o controle, clínico e radiográfico, em longo prazo, diagnosticando precocemente possíveis alterações e minimizando sequelas que podem acometer os dentes permanentes.(AU)

Terapia regenerativa en un incisivo central superior permanente inmaduro: caso clínico / Regenerative therapy in an immature permanent upper central incisor: a clinical case

Objetivo: Presentar la terapia regenerativa como una al- ternativa para la resolución de un caso de traumatismo denta- rio en un diente permanente incompletamente desarrollado. Caso clínico: Se realizó el tratamiento de un incisivo central superior con mortificación pulpar y periodontitis api- cal aguda subsecuente a trauma dental en un paciente de 8 años de edad. Se aplicó el protocolo de regeneración pulpar recomendado por la Asociación Americana de Endodoncia. Se estimuló la formación de un coágulo en el interior del con- ducto a partir de los tejidos periapicales, previa desinfección con la pasta triple antibiótica, y finalmente se colocó mineral trióxido agregado coronal a este. Se obtuvo así una matriz es- teril que permitió el crecimiento de nuevo tejido y se realiza- ron controles periódicos durante 4 años. Se constató silencio clínico. Radiográficamente, se observó la formación de tejido sobre las paredes del conducto y el cierre apical. Conclusión: La terapia regenerativa como alternativa de tratamiento, en este caso, permitió la disminución de la luz del conducto por el depósito de tejidos calcificados y el cierre del foramen apical, mejorando el pronóstico de la pieza dentaria (AU)

Aim: To present pulp regeneration therapy as an alter- native to resolve dental trauma in immature permanent teeth. Clinical case: We report a clinical case of an immature central superior incisor with pulp mortification and acute api- cal periodontitis subsequent to dental trauma, in an 8 year old patient. The pulp Regeneration protocol recommended by the American Endodontics Association was applied. We stimulated a clot formation inside the duct from periapical tissues and after disinfection with a mixture of three antibi- otics mineral trioxide aggregated was finally place coronal to the clot. Thus a sterile matrix was obtained that allowed new tissue's growth. Periodic check-up visits were carried out over a 4 years period. Clinical silence was observed. Tissue formation on duct walls and apical closure were radiograph- ically detected (AU) Conclusion: Regenerative therapy is an alternative for the treatment of immature permanent teeth, in ths clinical case it allowed the reduction of the width of the duct by the opposition of hard tissues and the closure of the apical fora- men improving the forecast of these teeth.

Efficacy of calcium hydroxide and chlorhexidine in pulp revascularization after trauma in young permanent teeth.

The objective of this study is to observe and analyze the efficacy of calcium hydroxide and chlorhexidine in pulp revascularization after trauma in young permanent teeth. A total of 120 patients who were treated in our hospital for pulp revascularization after trauma in young permanent teeth were enrolled as research objects in the study. The patients were treated with calcium hydroxide and chlorhexidine and the overall treatment efficiency was statistically observed. The improvement in various indicators before and after treatment was observed, including pain symptom score, gum swelling symptom score, tooth looseness score. The overall treatment efficiency was recorded. The results showed that there were 70 cases of significant effective treatment, 42 cases of effective treatment, and 8 cases of ineffective treatment, respectively, with overall treatment efficiency of 93.33%. Compared with the pain score, gum swelling score and teeth looseness score before treatment, these indicators showed a significant improvement after treatment, p<0.05. The application of calcium hydroxide and chlorhexidine during pulp revascularization after trauma in young permanent teeth can significantly improve the therapeutic effect and achieve higher therapeutic efficiency, demonstrating huge application value.

Incidence of root resorption after concussion, subluxation, lateral luxation, intrusion, and extrusion: a systematic review.

OBJECTIVE: Traumatic dental injuries often affect the dental hard tissues, periodontal tissues, and dental pulp. Root resorption (RR) is a significantly concerning phenomenon that could lead to loss of the traumatized tooth. The purpose of this systematic review was to analyze the incidences of different types of RR after concussion, subluxation, lateral luxation, intrusive luxation, and extrusive luxation. MATERIAL AND METHODS: Seven databases were electronically and manually searched for the identification of observational studies that evaluated the incidence of RR after luxation injuries. Following study selection, data extraction, and risk of bias assessment through MAStARI checklist, the GRADE quality of available evidence was assessed. RESULTS: In total, 14 studies were included in the present systematic review. Ten and four studies presented a moderate and low RoB, respectively, and the overall GRADE quality of evidence was "very low" for all outcomes. The highest incidence rates of RR were observed for teeth with intrusive luxation, followed by those with extrusive luxation, lateral luxation, subluxation, and concussion. In general, the most common type of RR documented for all injuries was inflammatory RR, followed by replacement RR, surface RR, and internal RR. CONCLUSIONS: Our findings suggest that RR most commonly occurs in association with intrusive luxation and by inflammatory RR. Awareness regarding the incidence of RR after injuries is useful for clinicians to minimize the risk and severity of its occurrence, because a late diagnosis of RR may limit treatment alternatives and result in tooth loss. CLINICAL RELEVANCE: Knowledge about the incidence of RR in teeth with concussion and different types of luxation injuries can ensure appropriate follow-up protocols and favorable outcomes.

Acute and Chronic Pain in Orofacial Trauma Patients.

Trauma or injury to the dentition and supporting tissues is associated with pain and discomfort, as expected, that may present immediately, shortly afterwards, or within a few days. Pain is an essential response to injury because it allows the organism to develop avoidance behavior to potential threats and helps the organism to avoid usage of the injured organ during the healing process. Not only does external trauma induce pain, but also essential invasive dental procedures such as extractions, dental implant insertions, root canal treatments, and oral surgeries are accompanied by similar post-surgical (post-traumatic) pain. The pain intensity after trauma varies and does not always correlate with the extent of injury. Trauma to the orofacial region or the teeth may also indirectly affect and induce pain in other orofacial structures such as the masticatory muscles, the temporomandibular joint, and even the cervical spine. In most cases, the pain will resolve as soon as healing of the affected tissue occurs or after dental and routine palliative treatment. In a limited number of cases, the pain persists beyond healing and evolves into a chronic pain state. Chronic pain in the orofacial region presents diagnostic and management challenges. Misdiagnosis or delayed diagnosis of the oral chronic pain condition may lead to unnecessary dental treatment. This article will discuss diagnosis and treatment for acute and chronic pain as well as potential mechanisms involved in the undesirable transition from acute to chronic pain.

Electromyographic characteristics of chewing muscles of individuals with pathological abrasion of hard dental tissues.

OBJECTIVE: Introduction: Pathological abrasion of hard dental tissues is accompanied by both morphological and functional disorders of the dentofacial system. Among the functional changes, changes in the bioelectrical activity of the masticatory muscles are primarily considered. The aim was to study the functional state of the masticatory muscles in patients with pathological abrasion of hard dental tissues of varying degrees of severity compared with the norm. PATIENTS AND METHODS: Materials and methods: Electromyographic studies were conducted in 89 patients aged 18 to 59. 70 patients had pathological abrasion of hard dental tissues of various degrees and 17 patients had intact dentitions and physiological forms of occlusion. RESULTS: Results: The results of electromyographic studies showed an extension of the chewing period, a reduced chewing rhythm, a deterioration of chewing efficacy in case of the pathological abrasion of teeth, compared with the norm, which increased in dynamics. The correlation between excitatory and inhibitory processes, however, sharply deteriorated with an increase in the duration of activity due to the reduction of the relative bioelectric rest period. The magnitude of the biopotential amplitude decreased relative to the norm with a serious violation of the coordination of masticatory muscles in general. CONCLUSION: Conclusions: The results of electromyographic studies of the masticatory muscles make it possible to determine the degree of functional changes in the neuromuscular system of the dentofacial system of patients with pathological abrasion of hard tissues of varying severity, compared with the norm. This indicates a decrease in chewing efficacy and the progression of morphological disorders that increase in dynamics.

Impact of uncomplicated traumatic dental injuries on the quality of life of children and adolescents: a systematic review and meta-analysis.

BACKGROUND: Traumatic dental injuries (TDIs) are highly prevalent during childhood and adolescence and have a significant effect on their oral health related quality of life (OHRQoL). Uncomplicated TDIs, dental trauma involving enamel, enamel and dentin and tooth discolorations, account for approximately two-thirds of all diagnosed TDIs in children and adolescents. Hence, it may be important to understand the impact of uncomplicated TDIs on OHRQoL, by synthesizing the available literature. METHODS: Medline, Embase, Web of Science and Scopus databases were systematically searched from January 1966 to April 2018. Studies that evaluated the effect of TDIs on the OHRQoL of children and adolescents using validated methods were selected for analysis. A narrative synthesis and a meta-analysis were performed. The studies were pooled according to age groups and OHRQoL questionnaire used. A random-effect model was applied to calculate the pooled odds ratios (OR) and their respective 95% confidence intervals. RESULTS: There were 712 identified studies. Of these, 26 articles were selected for the review and included in the narrative synthesis, 20 of these articles concluded that uncomplicated TDIs were not associated with a negative impact in OHRQoL. Seventeen were included in the meta-analysis. The estimates were pooled by age groups: children (OR: 1.01; 95%CI; 0.85-1.19; I2 = 51.9%) and adolescents (OR: 1.07; 95%CI; 0.91, 1.26; I2 = 50.2%).When pooling all estimates the OR was 0.96 (95% CI: 0.85-1.10; I2 = 61.4%). CONCLUSIONS: Uncomplicated TDIs do not have a negative impact on the OHRQoL of children and adolescents. Further prospective studies are needed to confirm the results of this review. The majority of the studies included were of cross-sectional design, which may have limited the ability to reach conclusions on the nature of this association. The PROSPERO systematic review registry is CRD42018110471.

Dental evaluation specificity in orofacial damage assessment: A serial case study.

INTRODUCTION: The evaluation of medico-legal post-traumatic events has been increasing over the last decades. This study analysed the input of dental evaluation in orofacial damage assessment, highlighting the individual's biopsychosocial model, by a serial case study. It is aimed to analyse the physical as well as the psychological repercussions of traumatic events. It also aimed to relate the type of trauma impact with the individual's sequelae. MATERIAL AND METHOD: An observational and retrospective study was carried out of Portuguese medico-legal database. A serial case study was distinguished by the direction of the impact: frontal striking, lateral striking and clashing with a bidirectional (frontal-lateral). RESULTS AND DISCUSSION: 7 cases fulfilled the inclusion criteria, as a pilot study. They have in common the involvement of the 2 lower thirds of the face, including the temporomandibular joint. The consolidation of the maxillary bone fractures does not always correspond to restituto ad integrum. CONCLUSION: The impact direction may guide clinical examination in detecting permanent impairment, emphasizing temporomandibular joint disorders, as well as their association with psychosocial repercussions. The medical-dental examination is differentiating and relevant to the accomplishment of the general objective of damage assessment.
