RESUMO

BACKGROUND: The occurrence of an orofacial trauma can originate health, social, economic and professional problems. A 13-year boy suffered the avulsion of tooth 11 and 21, lost at the scenario. METHODS: Three intraoral appliances were manufactured: A Hawley appliance with a central expansion screw and two central incisors (1), trumpet edentulous anterior tooth appliance (2) and a customized splint (3) were designed as part of the rehabilitation procedure. Objectively assessing the sound quality of the trumpet player with these new devices in terms of its spectral, temporal, and spectro-temporal audio properties. A linear frequency response microphone was adopted for precision measurement of pitch, loudness, and timbre descriptors. RESULTS: Pitch deviations may result from the different intra-oral appliances due to the alteration of the mouth cavity, respectively, the area occupied and modification/interaction with the anatomy. This investigation supports the findings that the intra-oral appliance which occupies less volume is the best solution in terms of sound quality. CONCLUSIONS: Young wind instrumentalists should have dental impressions of their teeth made, so their dentist has the most reliable anatomy of the natural teeth in case of an orofacial trauma. Likewise, the registration of their sound quality should be done regularly to have standard parameters for comparison.

RESUMO

BACKGROUND/AIM: In order to enrich epidemiological knowledge regarding traumatic dental injuries (TDI) in China, and to further improve the treatment, prevention and education of TDI, the aim of this study was to retrospectively analyze the TDI that presented to the emergency dental department at the Stomatological Hospital in Xi'an, China. METHODS: This retrospective study included all first-visit patients who presented with TDI at the Stomatological Hospital affiliated with the Fourth Military Medical University in Xi'an, China, between January 2013 and June 2019. Data were extracted using the terms of diagnosis of TDI from the hospital database. RESULTS: Overall, 965 (606 males and 359 females) files were reviewed. The average age was 22.8 ± 13.4 years. Among the 2059 teeth injured (average of 2.1 teeth per patient), the maxillary incisors (1751; 85.0%) were the most prevalent teeth to present with injuries, while the main types of injuries were concussions (14.8%) enamel-dentin-fractures (14.50%) and enamel-dentin-pulp fractures (14.0%). After initial examination and diagnosis, 4.2% patients refused treatment. CONCLUSIONS: The epidemiological statistics of TDI in Xi'an, China show consistency with other studies from around the world, but they also vary in diagnosis proportion and the choice of treatments. This information may further instruct treatment, prevention and emergency resources distribution to target the high-risk groups.

RESUMO

Background: Replantation of avulsed teeth is an invasive treatment approach where patient cooperation is required after the risks are explained to the patient or family. Although replantation of an avulsed permanent teeth is an accepted treatment approach, the long-term prognosis of the replanted teeth is still controversial. This report describes the survival of delayed replanted 15 incisors that was stored in unfavorable conditions after avulsion. Materials and Methods: Nine patients, aged 8-12 years, were referred to the Inonu University, Pediatric Dentistry Department with traumatically avulsed incisors. The parents were informed about the possible complications of a delayed replantation. Results: Forty percent of the teeth were splinted with flexible orthodontic wire and composite. The follow-up periods were varied from 24 to 48 months. The mean follow-up periods were 33.3 ± 8 months. 40% of the teeth were retained in the mouth for at least 3 years and contributed to alveolar bone development. In these cases, the most common complication (9 teeth, 60%) was replacement root resorption. Two of the 15 teeth which had wide open apices, continued to the root development. Conclusion: In this study, replanted teeth were retained in the mouth for at least 2 years and contributed to the patient's development. Therefore, this study has shown that delayed replantation of an avulsed tooth for a child is still worthwhile, even in cases of poor prognosis where the tooth had extended extra-alveolar dry storage. We believe that delayed replantation should be done because of its importance for the child's jaw and facial development.

RESUMO

BACKGROUND/AIMS: Management of traumatic dental injuries (TDI) can be expensive and time-consuming, yet very few studies have addressed the cost of their management. The aim of this study was to evaluate the total cost and the number of visits required to treat dental injuries to permanent incisors in children and adolescents over a 1-year period. MATERIALS AND METHODS: Ninety-five children with at least one traumatic dental injury to their permanent incisors were enrolled and managed according to the International Association of Dental Traumatology guidelines. Injuries were grouped into complex (n = 74) and non-complex injuries (n = 21) and divided by the date of injury. Total cost was the sum of the direct (capital, staff, materials and laboratory fees) and indirect costs (travel, childcare and missed working hours). All data were collected prospectively through hospital records and questionnaires at each visit over one year. Data were analysed using a linear regression model for the cost and the number of visits. Logistic regression was used to analyse differences between complex and non-complex injuries (α = 5%). RESULTS: The mean total cost for complex and non-complex injuries was €1687.9 and €1350.8, respectively. The treatment of non-complex injuries was cheaper than for complex injuries (P = .047). The cost of follow-up visits 4 years after the injury was significantly lower when compared to the treatment during the first year (P = .002). Travelling longer distances (>50 km) for treatment increased the overall cost of the treatment. There was no difference in the number of visits required for complex (mean = 5.6) and non-complex (mean = 4.9) injuries, but there were significantly fewer visits required in year 4 onwards (P < .001). CONCLUSION: Complex injuries presented a higher treatment cost, but the number of visits required was the same when compared to non-complex injuries over the 1-year evaluation. Further research in this area is encouraged to add to the limited available data.

RESUMO

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.

RESUMO

Mandibular incisors show variations in their root canal anatomy from regular pattern in some cases. Magnification plays a vital role to identify those unusual canal morphologies. A certain modification in access cavity preparation is required to locate those extra canals. Not only the functional restoration but also aesthetic harmony should be restored while treating anterior teeth. In these cases, post space preparation should be done with extra care to prevent vertical root fracture. This case report illustrates the importance of proper radiograph and magnification in the successful identification and management of complex canal systems in mandibular incisors.

RESUMO

Reattachment of a fractured fragment to the remaining tooth is challenging but one of the best treatment protocols in regards to aesthetics, function as well as patients acceptance. If the original tooth fragment is retained following fracture, the natural tooth structures can be reattached using adhesive protocols to ensure reliable strength, durability and aesthetics. This case report will discuss a 13 years old boy with a complicated crown-root fracture of maxillary right central incisor tooth. The procedure used to repair the fracture regarding this case including flap surgery with endodontic treatment. The root canal was filled with a root canal sealer and gutta-percha. After root canal obturation, fragment was reattached with an adhesive tooth reattachment technique. After 6 months evaluation, clinical and radiographic examinations showed a stable re-attachment, good aesthetic and healthy periodontium.

RESUMO

Aims and Objectives: The aim of this study was to assess the mean overjet in school-going Libyan children and to examine the relationship between increased overjet and permanent incisor's trauma. Materials and Methods: This study is a part of a cross-sectional investigation of aspects of dental health of 2015 school going Libyan children aged between 6 and 16 years old of both genders from both rural and urban areas. Overjet was measured as the horizontal distance in millimetres between the upper and lower incisors. Trauma to permanent incisors was assessed according to Elli's Classification. Results: SPSS version 20.0 for percentages was used for statistical analysis. The relationship between increased overjet and incisor trauma was tested using the Chi-square test at 0.05 significance level. The overjet measurement ranged from -2 mm to 8 mm with the mean overjet of 3.062 (1.23, SD). The prevalence of incisor trauma was statistically significantly higher in children with increased overjet (P < 0.0001). Conclusion: The average mean overjet value in Libyan children is between 2 mm and 3 mm and below or above these values, considered decreased or increased, respectively. Traumatic injuries to permanent incisors significantly increased with increased overjet.

RESUMO

Abstract Objective: To evaluate the factors associated with the occurrence of dental trauma in children up to six years of age and describe the results of clinical follow-up and possible sequelae. Material and Methods: A retrospective study was carried out with data collected from the dental records of 96 pediatric patients up to 6 years old with traumatized primary teeth who sought care from the. Pediatric Dental Trauma project of a private university in the city of Rio de Janeiro from July 2014 to July 2017, and who had clinical and radiographic follow-up for up to three months as of their initial visit. Results: 96 children (58.3% boys and 41.7% girls) included who presented 166 traumatized primary teeth. Intrusion was the most observed type of trauma and in 45.8% of cases, the care occurred one-week post trauma. The maxillary central incisors were the most affected teeth (97.6%). The prognosis of the dental elements with more than 3 months of follow-up was considered favorable, and 59.6% of the teeth did not present any clinical or radiological sequelae. Oral hygiene instruction and monitoring were the most common approaches. Conclusion: The prevalence of dental trauma in the present study was high and occurred mainly in domestic settings. The upper central incisors were the teeth that suffered the most injuries. The presence of patients at follow-up visits was an important factor for the positive result in most cases.

RESUMO

BACKGROUND: Modern cone beam computed tomography (CBCT) acquisition and three-dimensional (3D) image processing, combined with direct metal laser sintering (DMLS), allows custom-made, root-analogue implants (RAIs). PURPOSE: To demonstrate how DMLS permits customized titanium RAI production, with immediate insertion and restoration in a fresh extraction socket of the anterior maxilla. MATERIALS AND METHODS: A titanium RAI perfect copy of the radicular unit needed for replacement was created by customized DMLS, and inserted into a fresh extraction socket of the esthetic area of the anterior maxilla. RESULTS: Follow-up after 1 year: the DMLS RAI implant showed a satisfactory functional and esthetic integration, with no bone resorption or soft tissue recessions. CONCLUSIONS: The production of customized DMLS RAIs opens new interesting perspectives for immediate implantation. KEY WORDS: Direct metal laser sintering, Root analogue implant.

RESUMO

Objetivo: Informar el tratamiento de dos piezas con fractura radicular horizontal del tercio medio, patrones de curación y seguimiento por cinco años. Caso clínico: Se presentó a la consulta una niña de 9 años de edad con traumatismo de 10 días de evolución. Examen clínico: fractura amelodentinaria restaurada en la pieza 2.2, movilidad y sensibilidad a la percusión y palpación en ambos incisivos centrales superiores. Examen radiográfico: fractura radicular horizontal de tercio medio en piezas 1.1 y 2.1. Tratamiento: inmovilización con placa removible durante 4 semanas, indicaciones de higiene y uso, y controles de seguimiento. Al primero y al cuarto mes, ambos incisivos mostraron ausencia de movilidad, reacción positiva de sensibilidad y signos radiográficos de reabsorción superficial interna y externa. A los 6 meses, el 1.1 evidenció signos de reparación con tejido conectivo, y el 2.1, signos clínicos y radiográficos de necrosis pulpar del fragmento coronario. Se realizó el tratamiento endodóntico de la pieza 2.1 hasta el nivel de la fractura con pasta a base de hidróxido de calcio, y luego de la comprobación de la formación de una barrera de tejido duro, se obturó definitivamente con gutapercha y sellador endodóntico. Cinco años después del traumatismo, ambos incisivos se mostraron asintomáticos y los estudios por imágenes evidenciaron una completa consolidación de las fracturas. Conclusión: Un diagnóstico temprano, procedimientos apropiados de tratamiento, el conocimiento de los procesos curativos y un monitoreo cuidadoso de todos los parámetros clínicos y radiográficos son claves para un enfoque correcto y conservador de las piezas dentarias con fractura radicular (AU)


Aim: To report the treatment, healing patterns and fiveyear follow-up of two permanent incisors with horizontal root fracture located in the middle third. Case report: A 9-year-old girl who came to our consultation 10 days after a dental trauma. Clinical examination: restored enamel-dentin fracture in upper left lateral incisor; mobility and sensitivity to percussion and palpation in both upper central incisors. Radiographic examination: horizontal root fracture in the middle third of both upper central incisors. Treatment: stabilization with a removable splint for 4 weeks, indications for hygiene, use of the splint and follow-up controls. At first and fourth month, central incisors presented absence of mobility, positive response to pulp testing and radiographic signs of internal and external superficial resorption. At sixth month, signs of healing with connective tissue were found on the right central incisor, while the left one showed clinical and radiographic signs of necrosis of the coronal fragment. The root canal of this segment was treated initially with a calcium hydroxide paste and, after verifying the formation of a hard tissue barrier, it was filled with gutta- percha and endodontic sealer. Five years after the trauma, both central incisors were asymptomatic and imaging studies showed complete healing of the fractures. Conclusion: Early diagnosis, appropriate treatment procedures, knowledge of healing patterns and careful monitoring of clinical and radiographic parameters are key factors for a proper and conservative approach of injured tooth with root fracture (AU)

RESUMO

Dental trauma is a common complication of tracheal intubation. As existing evidence is insufficient to validly assess the impact of different laryngoscopy techniques on the incidence of dental trauma, the force exerted onto dental structures during tracheal intubation was investigated. An intubation manikin was equipped with hidden force sensors in all maxillary incisors. Dental force was measured while 104 anaesthetists performed a series of tracheal intubations using direct laryngoscopy with a Macintosh blade, and videolaryngoscopy with a C-MAC® , or the hyperangulated GlideScope® or KingVision® laryngoscopes in both normal and difficult airway conditions. A total of 624 tracheal intubations were analysed. The median (IQR [range]) peak force of direct laryngoscopy in normal airways was 21.1 (14.0-32.8 [2.3-127.6]) N and 29.3 (17.7-44.8 [3.3-97.2]) N in difficult airways. In normal airways, these were lower with the GlideScope and KingVision hyperangulated laryngoscopes, with a reduction of 4.6 N (p = 0.006) and 10.9 N (p < 0.001) compared with direct laryngoscopy, respectively. In difficult airways, these were lower with the GlideScope and KingVision hyperangulated laryngoscopes, with a reduction of 9.8 N (p < 0.001) and 17.6 N (p < 0.001) compared with direct laryngoscopy, respectively. The use of the C-MAC did not have an impact on the median peak force. Although sex of anaesthetists did not affect peak force, more experienced anaesthetists generated a higher peak force than less experienced providers. We conclude that hyperangulated videolaryngoscopy was associated with a significantly decreased force exerted on maxillary incisors and might reduce the risk for dental injury in clinical settings.

RESUMO

The major challenge in traumatic injuries is the management of subgingival fracture of anterior teeth. Forced orthodontic extrusion is a suitable approach for these teeth as it provides both a sound tissue margin for final restoration and creates a periodontal environment (biological width) which is easy for the patient to maintain. Restoration after orthodontic eruption may present a more conservative treatment choice in young patients compared with the prosthetic restoration after extraction. This paper reports a case of the fractured maxillary anterior tooth at the subgingival level that was managed by forced orthodontic extrusion after endodontic therapy followed by aesthetic rehabilitation, a much-forgotten technique not utilised routinely yet conservative and cost-effective.

RESUMO

Each year, millions of children are injured and live with the consequences of those injuries. Through infancy and childhood, orofacial trauma caused by falls or being struck by or against objects occurs in children. The long-term implications on the developing permanent teeth are little known, even when the oral region is the second most frequently injured body area in children under 6 years of age. During this period, the developing permanent teeth may be directly involved after trauma, causing mild to severe hypoplasia, displacement, damage to the tooth germ, or an extended range of morphofunctional disturbances. In some cases, the effects of oral and dental injuries caused by trauma appear later with the eruption of the permanent incisors when ectopic eruption, malalignments, and other developmental disturbances become visible. Therefore, long-term follow up of the patient in order to diagnose and treat associated complications becomes essential. Critical points for facing the consequences of orofacial trauma on the developing dentition are to recognize the impact of orofacial trauma in young children and the dentist's role in providing anticipatory guidance to parents and health care professionals, differentiate between mild and severe disturbances affecting the developing permanent teeth after oral injuries in early childhood, recognize the importance of follow-up controls, and recognize the importance of early referral to a pediatric dentist and orthodontist for diagnosis and treatment planning.

RESUMO

Objective: The objective of this study was to determine the prevalence of traumatic dental injuries (TDIs) in the anterior teeth among children attending paramilitary and nonparamilitary schools in Benin City, Nigeria. Materials and Methods: A multistage sampling technique was used to select children aged 8-12 years with a previous history of trauma to the orofacial region. A self-administered questionnaire was then applied, and each participant was examined clinically. Data collected included demographic characteristics, etiology and place of injury, affected teeth, type of dental injury, lip competence, and overjet values. Analysis of data was done with the SPSS version 21.0 software. Pearson's Chi-squared test was used to determine the association between variables and odds ratio. Statistical significance was determined at P < 0.05. Results: A total number of 1352 children (mean age: 9.89 ± 1.4 years) were examined and 154 (11.4%) had a previous history of TDI. The prevalence among respondents in the paramilitary schools was 84 (6.2%) and those in nonparamilitary schools 70 (5.2%). Falls and play was the most common cause of TDI and was higher in children in paramilitary schools. Ellis Class I was the most prevalent type of injury in 91 (59.1%), tooth number 21 was the most traumatized, and the school environment was the most common place. Of the total number of respondents with TDI, the relationship between etiology with age, lip competence, and overjet was statistically significant (P < 0.05). Conclusion: The prevalence of TDI among the study participants was 11.4% and more in the paramilitary schools than the nonparamilitary.

RESUMO

A 3 year and 8 months old Chinese boy was referred for a consultation regarding his missing maxillary anterior teeth. He had a history of trauma to his primary maxillary anterior teeth due to a fall at the age of 16 months. Clinical examination of the patient indicated multiple carious lesions and inadequate oral hygiene. Radiographic examination revealed intrusion of the primary left lateral incisor, with evidence of damage to the permanent tooth germ. Subsequently, the patient was followed-up for almost six years during which his permanent maxillary left lateral incisor erupted exhibiting an unusual morphology. Clinically enamel hypoplasia and radiographically dens invaginatus were evident in affected tooth.

Cemental tear represents a rare form of root surface fracture which makes teeth prone to periodontal breakdown. The diagnosis of cemental tear becomes a challenge as it is usually neglected or misdiagnosed and is also underreported in the literature. Correct diagnosis and early treatment of cemental tear can prevent further periodontal breakdown and may preserve the affected tooth for a longer duration. This case presents the diagnosis, treatment, and an analysis of a right maxillary lateral incisor with an improper endodontic treatment coupled with a cemental tear. Despite surgical removal, the cemental tear led to the development of an endodontic periodontal lesion. This article intends to help recognize early signs and symptoms of cemental tear and establish timely diagnosis. It determines that if the periodontal destruction caused by cemental tears is diagnosed and treated early, it may be possible to prevent further periodontal breakdown and preserve the tooth for a longer period.

RESUMO

INTRODUCTION: Regenerative endodontic procedures (REP) are a novel treatment modality to restore the function of necrotic pulp tissue via stimulation or transplantation of stem cells into the root canal. This study aimed to investigate the immunohistologic outcome of 3 extracted teeth because of sequelae of trauma and unsatisfactory REP outcomes. METHODS: Three immature permanent maxillary central incisors of 3 female patients (6-9 years) were extracted 5.5-22 months after REP. Additionally, 1 sound permanent immature central maxillary incisor of 1 of the included patients was extracted for orthodontic reasons. The teeth were immunohistologically stained with Masson's trichrome, neurofilament (NF), pan cytokeratin, dentin sialophosphoprotein, and Gram+/-. RESULTS: The REP-teeth presented intracanalar vascularized connective/mineralized reparative tissue (RT), which was less organized than the pulp tissue of the sound tooth. Moderate to considerable calcification was observed below the Portland cement used during REP. In 1 case, the RT was NF+; in the 2 other cases, the periodontal ligament and apical granuloma/papilla were NF+. All teeth were Gram+/- negative; nevertheless, inflammatory cells were present in 2 cases. The pan cytokeratin and dentin sialophosphoprotein stainings were not specific enough for 2 cases. CONCLUSIONS: This immunohistologic study of failed REP cases resulted in bacteria-free intracanalar RT and biomaterial-induced calcification. Nevertheless, the presence of inflammatory cells revealed a persistent inflammation. Hence, the clinical and radiographic signs were decisive for tooth survival and multidisciplinary outcome determination.
