Parestesia do nervo alveolar inferior decorrente de procedimentos cirúrgicos e suas formas de tratamentos / Paresthesi of the lower alveolar nerve resulting from surgical procedures and its forms of treatment

Nas cirurgias odontológicas é possível que ocorra alguns acidentes ou complicações que podem interferir no dia a dia do paciente. A lesão do nervo alveolar inferior é uma complicação decorrente de cirurgias orais que podem causar um distúrbio de sensibilidade transitória ou persistente, na região do lábio inferior e na região delimitada do forame mentoniano e hemi-arco da mucosa. O diagnóstico da parestesia pode ser feito através de testes mecanoceptivos e nocioceptivos em que o profissional escolherá para qual melhor se adapte no paciente. O objetivo do presente trabalho foi abordar por meio de uma revisão de literatura as formas de diagnóstico e tratamento da parestesia do nervo alveolar inferior decorrentes de cirurgias orais. As bases de dados utilizadas para confecção desta revisão são encontradas nas bibliotecas virtuais eletrônicas: BVS (Biblioteca Virtual em Saúde), LILACS (Literatura Latino-Americana e do Caribe em Ciências da Saúde) e Pubmed. Como critério de inclusão foram selecionados artigos publicados de 2012 a 2022 em língua inglesa, portuguesa e espanhola. Após a leitura do título e resumo dos resultados da pesquisa e aplicação dos critérios de inclusão e exclusão dentre eles foram excluídos 883, pois não se enquadravam no nosso critério de inclusão. No final, foram selecionados 13 estudos por meio de base de dados, que serviram de base para esta revisão. Concluímos que as formas de tratamento para a parestesia na literatura, são um pouco escassas e conflitantes, mas relata que o uso da laserterapia e acupuntura tem sido uma forma de tratamento com um bom índice de sucesso, e para os casos que não sejam suficientes tais tratamentos, pode-se optar por uma cirurgia(AU)

In dental surgeries it is possible to have some accidents or complications that can interfere with the patient's day. Injury to the inferior alveolar nerve is a complication resulting from oral surgeries that can cause a disturbance of sensitivity that can be transient or persistent in the region of the lower lip and in the delimited region of the mental foramen and hemiarch of the mucosa. The diagnosis of paresthesia can be made through mechanoceptive and nocioceptive tests that the professional will choose, which best suits the patient. The objective of the present work is to approach, through a literature review, the forms of diagnosis and treatment aimed at inferior alveolar nerve paresthesia resulting from oral surgeries. The databases used for this review are found in the virtual electronic libraries: VHL (Virtual Health Library), LILACS (Latin American and Caribbean Literature on Health Sciences) and Pubmed. As inclusion criteria, articles published from 2012 to 2022 in English, Portuguese and Spanish were selected. After reading the title and summary of the research results and applying the inclusion and exclusion criteria, 883 were excluded, as they did not meet our inclusion criteria. In the end, 13 studies were selected from the database, which served as the basis for this review. We conclude that the forms of treatment for paresthesia in the literature are a little scarce and conflicting, but it reports that the use of laser therapy and acupuncture has been a form of treatment with a good success rate, and for cases that are not enough, such treatments, one can opt for surgery(AU)

Waste management practices among dental surgery staff of major hospitals in Accra: a descriptive cross-sectional study

Introduction: the practice of dentistry in contemporary times produces considerable waste that could be harmful to individuals and the environment at large. In Ghana and many other jurisdictions, there are guidelines that outline how these wastes should be managed. This study was conducted to explore practices concerning dental waste management among dental surgery staff in some public facilities in Accra, Ghana. Methods: a descriptive cross-sectional study involving dental surgery staff of four major facilities in Accra was done. Overall, 124 staff from the selected facilities participated in the study, and 51 different dental surgeries were assessed. Data were collected using a structured questionnaire and an observation checklist. The questionnaire included questions on socio-demographics, as well as knowledge and practices regarding dental waste management. Results: there was unsatisfactory knowledge of waste disposal, while practices did not generally meet international recommendations and the Ministry of Health´s (MOH) guidelines. Though all respondents stored their sharp waste in puncture-proof containers, 98.4% did not label their clinical waste, while 62.9% would dispose of used X-ray fixers by pouring them down the drain. None of the 51 surgeries observed had more than one colour code available. Conclusion: there is a palpable need for education, monitoring, and empowerment concerning waste management in Ghana´s oral healthcare system.

Anterior Teeth Measurement among Subjects in the University of Port Harcourt as a Sex Indicator and Aid to Maxillofacial Reconstruction

Background: The aim of this study is to determine sexual dimorphism using anterior teeth measurements and its use as an ancillary tool for sexual determination. Methods:In this study, the measurements of the anterior teeth were carried out on one hundred and forty students (80M: 60F) of the University of Port-Harcourt ranging from 15-30 years. The mesiodistal diameter of the central and lateral incisors, right and left canines and their inter-canine distance were measured. These measurements were done with the aid ofa digital Vernier caliper. Also, the percentages of sexual dimorphism were calculated. The values were subjected to statistical analysis.Results:The mean mesiodistal central incisor (MDCI) value for males was 9.78 ± 0.47mm while that of the females was 9.29±0.46mm. The mean mesiodistal lateral incisor (MDLI) value for males was 7.80 ±0.54mm while that of the females was 7.40±0.54mm. The mean mesiodistal right canine (MDRC) value for males was 7.43±0.49mm while that of the females was 7.04±0.40mm. The mean mesiodistal left canine (MDLI) value for males was 7.39±0.51mm while that of the females was 7.03±0.55mm. The mean mandibular inter-canine distance (MICD) value for males was 33.73±1.15mm while that of the females was 32.23±0.98mm. They were all statistically significantat p<0.05.Conclusion:It can be concluded that the incisors and the canines are useful tools in sex determination. The data obtained can be useful in maxillofacial reconstructive surgery

Sialolitiasis, sialoadenitis y sialoadenosis. Revisión de literatura y reporte de un caso clínico / Sialolithiasis, sialadenitis and sialadenosis. Review of literature and report of a clinical case

Introducción: la formación de sialolitos se considera la alteración más común en las glándulas salivales. Su origen aún no es claro en cuanto a qué provoca la obstrucción parcial o total del sistema de conductos salivales, con una predilección significativa en las glán - dulas submandibulares, lo que permite un desplazamiento retrógrado de bacterias a través del conducto salival hacia la glándula afectada, el cual se traducirá clínicamente como inflamación unilateral o bila - teral. El tratamiento para la sialolitiasis y sialoadenitis puede variar desde un manejo conservador hasta tratamientos que implican la remoción de la glándula salival afectada. La sialoadenosis difiere de las anteriores en su origen, ya que ésta no se considera inflamatoria ni neoplásica y no afecta la función glandular de excretar saliva. Presentación de caso clínico: se trata de paciente masculino con diagnósticos presuntivos de sialoadenitis y sialolitiasis, al cual se le realizó biopsia escisional de la glándula afectada, su estudio histo- patológico corroboró los diagnósticos mencionados anteriormente que además confirmó un diagnóstico de sialoadenosis. Conclusio- nes: la escisión de la glándula salival involucrada se realizará en casos diagnosticados de sialoadenitis y sialolitiasis con sialolitos de gran tamaño y procesos supurativos crónicos que no resuelven con antibioticoterapia (AU)

Objective: As the frequency of patients using anticoagulants and antiplatelet agents in dental offices is increasing, this study aimed to evaluate, through a Literature Review, which is the best management of these medications in dental perioperative practice. Methodology: This is an integrative literature review, being used Scielo and PubMed databases. The following descriptors available in BVs and PubMed "Platelet aggregation inhibitors", "Oral Surgical Procedures" and "Antigoagulants" were used, from 2016 to 2021. In addition, the search was also performed in guideline books and Government websites. Twenty articles were chosen for research elaboration. Results: established cardiovascular disease and other procoagulant clinical conditions have an increasing prevalence, especially among the elderly, and are known risk factors for the occurrence of severe thromboembolic phenomena. Antithrombotic therapy has defined role in these cases. In the perioperative period of oral surgery, the decision to suspend or maintain therapy must be individualized and may be guided by guidelines. Age appears as a clinical criterion in the main ones used. Conclusion: oral procedures with low risk of bleeding can be carried out without discontinuing antithrombotic therapy. Moderate to high-risk surgeries usually require its temporary suspension in order to minimize the risk of bleeding complications... (AU)

Tratamento cirúrgico em fratura de mandíbula atrófica: uma revisão de literatura / Surgical treatment of atrophic jaw fracture: a literature review

Analisar o manejo de fraturas em mandíbula atrófica voltado para a abordagem cirúrgica com ênfase na melhor técnica indicada. A perda óssea alveolar tem sido uma das consequências do edentulismo, que tem o potencial de levar a atrofia óssea. As fraturas de mandíbulas atróficas, normalmente são consideradas um procedimento desafiador, devido ser encontrada em pacientes idosos ou em virtude da perda dentária precoce resultando em um reparo dessas fraturas mais complexo. Os principais fatores etiológicos têm sido os acidentes automobilísticos, seguidos de queda e agressão. Geralmente, as causas das quedas decorrem de desequilíbrio, fraqueza muscular, tontura, e uso crônico de medicamentos como sedativos. As opções terapêuticas objetivam restaurar forma, função e imobilização apropriada desse possível evento. A individualização do tratamento de escolha é de grande importância, pois geralmente o paciente apresenta alterações fisiológicas decorrentes do envelhecimento e ossos mais fragilizados com potencial osteogênico reduzido, que dificultam a abordagem cirúrgica. Entretanto, deve ser considerado para o manejo dessas fraturas, a idade do paciente, as condições e quantidade de tecido ósseo e tecido mole. Porém, vale ressaltar que o envelhecimento não apresenta contraindicação, apenas exige condições especiais que devem ser consideradas. Nesse sentido, quando há oportunidade de dispositivos tecnológicos, como os biomodelos que contribuem significativamente para procedimentos cirúrgicos bucomaxilofaciais, esses fornecem maior previsibilidade de resultados, bem como redução do tempo cirúrgico.

To analyze the management of fractures in atrophic mandible aimed at the surgical approach, emphasizing which technique is best indicated. Alveolar bone loss has been one of the consequences of edentulism, which has the potential to lead to bone atrophy. Atrophic jaw fractures are usually considered a challenging procedure, as they are found in elderly patients or due to early tooth loss, resulting in a more complex repair of these fractures. The main etiological factors have been described as car accidents, followed by falls and aggression. Commonly, the causes of falls stem from imbalance, muscle weakness, dizziness, and chronic use of medications such as sedatives. The therapeutic options aim to restore form, function and appropriate immobilization of this possible event. The individualization of the treatment of choice is of great importance, as the patient usually presents physiological changes resulting from aging and more brittle bones and a reduced osteogenic potential, which makes the surgical approach difficult. However, the patient's age, conditions and amount of bone and soft tissue must be taken into consideration for the management of these fractures. However, it is noteworthy that aging has no contraindication, it only requires special conditions that must be considered. In this sense, when there is an opportunity for technological devices, such as biomodels that significantly contribute to maxillofacial surgical procedures, it provides greater predictability of results, as well as reduced surgical time.

Evaluation of the effectiveness of arnica montana 6ch in the control of postoperative myalgia by isometric effort in dentistry

Arnica montana 6CH is a medicine indicated for inflammatory and painful conditions, especially in muscle structures. The RDC / TMD Axis II questionnaire is a validated tool for the diagnosis of Temporomandibular Muscle Dysfunction. Objective: This multicenter, randomized and controlled study, approved by Human or Animal Research Ethics Committee UniFOA -CAAE: 48680015.3.0000.5237 aimed to verify the clinical performance of Arnica montana 6CH in contractures and muscle pain triggered by isometric stress. Materials and Methods: 70 patients underwent prolongeddental treatment sessions, and they were selected after clinical examination and positive responses to the RDC / TMD questionnaire to confirm signs and symptoms of Temporomandibular Muscle Dysfunction at the first consultation. Randomly, Arnica montana 6CH was prescribed for 35 patients called group I, and placebo for 35 patients called group II, at a dose of 5 globules, 03 times a day, for 1 week. In the second endodontic consultation, after 15 days, a new clinical examination was performed at the beginning and end of the prolonged dental consultation with crossing of data from the RDC questionnaire, to monitor the prevalence of TMD muscle signs and symptoms. The data were tabulated and analyzed. Statistical analysis: The test t de Student was used for paired samples, significant at the level ≤ 0.05%. Results:Anamnetic data from the RDC questionnaire, 86% of the individuals in the GI had lower pain and muscle contracture rates in the second consultation, compared with 22% in the GII. Conclusion:The drug Arnica montana 6CH proved to be effective in preventing muscle changes and clinical symptoms resulting from isometric efforts with a statistically significant difference (p ≤ 0.05).

Quiste inflamatorio con tejido calcificado: presentación de un caso clínico / Inflammatory cyst with calcified tissue: presentation of a clinical case

Objetivo: Describir un caso de quiste odontogénico in- flamatorio cuya presentación imagenológica no es la habitual. Caso clínico: Acude a la clínica profesional de Pato- logía Oral de la Universidad Andrés Bello una paciente de género femenino de 13 años, sin antecedentes mórbidos, con un hallazgo radiográfico de lesión mixta ubicada entre los premolares inferiores derechos. Es derivada al posgrado de cirugía oral y maxilofacial para que le realicen una biopsia excisional de la lesión con una hipótesis diagnóstica de tumor odontogénico adenomatoide. Una vez realizado el estudio histopatológico, se define la lesión como quiste odontogénico inflamatorio, que por las características clínicas-radiográficas podría corresponder con un quiste residual de un diente tem- poral. Debido a la variabilidad en la presentación clínica e ima- genológica de las lesiones quísticas maxilofaciales, el estudio anatomopatológico es imprescindible para un correcto diag- nóstico y tratamiento (AU)

Aim: To present a case of inflammatory odontogenic cyst with unusual imaging presentation. Clinical case: A 13-year-old female patient, with no history of morbidity, with a radiographic finding of a mixed lesion located between the lower right premolars. The patient visited the professional Oral Pathology clinic of the Andrés Bello University and was referred to postgraduate oral and maxillofacial surgery for an excisional biopsy of the lesion, with a diagnostic hypothesis of adenomatoid odontogenic tu- mor. After the histopathological study, the lesion was defined as an inflammatory odontogenic cyst, which, based on clini- cal-radiographic characteristics, could be a residual cyst of a primary tooth. Due to the variability in the clinical and imaging pres- entation of maxillofacial cystic lesions, anatomopathological study is essential for correct diagnosis and treatment (AU)

Incidencia de consultas por fracturas maxilofaciales en un servicio de urgencias odontológicas del Área Metropolitana de Buenos Aires / Incidence of consultations for maxillofacial fractures in a dental emergency department in the Metropolitan Area of Buenos Aires

Objetivo: Describir la incidencia, la causa, el patrón y el tratamiento de fracturas maxilofaciales en sujetos que solici- taron atención en un Servicio de Urgencias Odontológicas del Área Metropolitana de Buenos Aires. Materiales y métodos: Se analizaron las historias clíni- cas de los individuos que concurrieron al Servicio de Urgencias y Orientación de Pacientes de la Facultad de Odontología de la Universidad de Buenos Aires (SUyOP) en el período compren- dido entre marzo de 2018 y diciembre de 2019. Se registró la fre- cuencia de consultas vinculadas con diagnóstico de algún tipo de fractura del esqueleto maxilofacial y en el caso de estos pacien- tes, se registraron sexo, edad, etiología, ubicación y tratamiento. Resultados: Durante el periodo evaluado asistieron al SUyOP un total de 13.919 pacientes por algún tipo de urgen- cia odontológica, entre los cuales 47 (0,33%) se presentaron con traumatismos en la región bucomaxilofacial; 39 fueron del sexo masculino (83%). En total fueron diagnosticadas 66 frac- turas. La edad media se extendió entre los 30 y los 51 años. Las fracturas se encontraron con mayor frecuencia en la mandíbu- la (95,45%). La agresión interpersonal fue la principal causa (53,19%). El tratamiento realizado con mayor frecuencia fue el bloqueo intermaxilar en el 57,44% de los pacientes. Conclusión: Las fracturas de maxilar inferior fueron las que se registraron con mayor frecuencia. Si bien estas fracturas no ponen en riesgo la vida del paciente, la falla en el diagnóstico y el tratamiento apropiados puede derivar en la pérdida de fun- ciones del sistema estomatognático, y desarrollar deformidades secundarias que requieren de un tratamiento más complejo (AU)

Aim: To describe the incidence, etiology, pattern and treat- ment of maxillofacial fractures in a dental emergency department of the Buenos Aires Metropolitan Area. Materials and methods: A study was conducted, re- cording sex, age, etiology, location and treatment of maxillofa- cial fractures in patients who visited the Emergency and Patient Orientation Service of the School of Dentistry of the University of Buenos Aires (SUyOP) from March 2018 to December 2019. Data were obtained from dental medical records. Results: During the evaluated period, a total 13,919 pa- tients visited the SUyOP for dental emergencies, of whom 47 (0.33%) presented with trauma in the oral-maxillofacial region, and 39 were male (83%). Age range was 30 to 51 years. Over- all, 66 fractures were diagnosed. Fractures were most frequent in the mandible (95.45%). Interpersonal aggression was the most prevalent cause (53.19%). The most frequent treatment was inter- maxillary fixation, which was performed in 57.44% of the cases. Conclusion: Fractures of the lower jaw were the most fre- quently reported. Although these fractures are not life-threaten- ing, failure to diagnose and treat them properly can lead to loss of function of the stomatognathic system and development of sec- ondary deformities requiring more complex treatment (AU)

Evaluation of palatal volume in children with cleft lip and palate: a comparison of two surgical protocols / Avaliação volumétrica do palato em crianças com fissura labiopalatina: comparação de dois protocolos cirúrgicos

Objective: Compare the palatal volume in children with unilateral cleft lip and palate before and after two surgical protocols. Material and Methods: Retrospective data collection was performed in a specialized hospital. The sample comprised 120 digitized dental models divided into, Group 1 (G1) ­ participants submitted to cheiloplasty at 3 months (Millard technique) and one-step palatoplasty at 12 months (von Langenbeck technique); Group 2 (G2) ­ participants submitted to cheiloplasty (Millard technique) and hard palate closure (Hans Pichler technique) at 3 months and soft palate closure at 12 months (Sommerlad technique). The dental models were evaluated at Time 1 (T1): before primary plastic surgeries, Time 2 (T2): 1st post-surgical phase, and Time 3 (T3): 2nd post-surgical phase. The volume was measured through stereophotogrammetry system software. Parametric and non-parametric statistical tests were applied (α=5%). Results: The intragroup analysis revealed that G1 had a statistically significant increase in volume at T2 followed by a reduction at T3 (p=0.003); G2 showed a statistically significant increase of dental arch volume between T1 and T2 (p=0.001). There was no statistically significant difference in the intergroup and gender analyses (p>0.05). Conclusion: The surgical protocol influenced the palatal volume of children with unilateral cleft lip and palate. This study suggested that two-step palatoplasty protocol has a tendency to be more appropriate.(AU)

Objetivo: Comparar o volume palatino em crianças com fissura unilateral de lábio e palato antes e após dois protocolos cirúrgicos. Material e Métodos: A coleta de dados retrospectiva foi efetuada em um hospital especializado. A amostra foi composta por 120 modelos dentários digitalizados divididos em, Grupo 1 (G1) ­ participantes submetidos a queiloplastia aos 3 meses de vida (técnida de Millard) e a palatoplastia em única etapa aos 12 meses (técnica de von Langenbeck); Grupo 2 (G2) ­ participantes submetidos a queiloplastia (técnica de Millard) e fechamento do palato duro (técnica de Hans Pichler) aos 3 meses de vida e fechamento do palate mole aos 12 meses (técnica de Sommerlad). Os modelos dentários foram avaliados em Tempo 1 (T1): antes das cirurgias plásticas primárias, Tempo 2 (T2):1ª fase pós-cirúrgica e Tempo 3 (T3): 2ª fase pós-cirúrgico. O volume foi mensurado por meio do software do sistema de estereofotogrametria. Testes estatísticos paramétricos e não-paramétricos foram utilizados (α=5%). Resultados: As análises intragrupos indicaram que G1 apresentou aumento estatisticamente significante em T2 seguido de redução em T3 (p=0.003). G2 apresentou crescimento estatisticamente significativo do volume palatino entre T1 e T2 (p=0.001). Não houve diferença estatisticamente significante nas análises intergrupos e entre gêneros (p>0.05). Conclusão: O protocolo cirúrgico influenciou o volume palatino das crianças com fissura unilateral de lábio e palato. Este estudo sugeriu que o protocolo da palatoplastia em duas etapas possui uma tendência de ser mais apropriado.(AU)

Granuloma piógeno en el dorso lingual: caso clínico / Pyogenic granuloma in the lingual dorsum: a clinical case

El granuloma piógeno es una lesión benigna en la cavidad bucal, no neoplásica. Es una entidad fre- cuentemente asociada a la expansión de los tejidos blandos de la cavidad bucal. Se presenta, con mayor frecuencia, en individuos del género femenino, con edades comprendidas entre la segunda y cuarta década de vida. El tratamiento es mediante escisión quirúrgica con un pequeño margen de seguridad, y los agentes irritantes deben extraerse concomitan- temente para la curación de la lesión. Este trabajo tuvo como objetivo informar un caso de granuloma piógeno en el dorso de la lengua en una paciente del género femenino de 69 años. Los autores destacaron la importancia del conocimiento de la patología bucal por parte del Cirujano Dentista para poder realizar un correcto diagnóstico diferencial de otras lesiones, con el fin de realizar el tratamiento adecuado (AU)

Pyogenic granuloma is a quite common non-neoplasic benign lesion in the oral cavity. It is one of the entities most frequently associated with the soft tissues' expansion of the oral cavity, specifically in females, in the age group between the second and the fourth decade of life. The treatment is by surgical excision with a small margin of safety. For the healing of the lesion irritants should be concomitantly removed. This study aimed to report a case of pyogenic granuloma on the lingual dorsum of a 69-year-old female patient. The authors concluded highlighting the importance of the knowledge of oral pathology by the Dental Surgeon, to perform a correct differential diagnosis of other lesions to perform the appropriate treatment (AU)

Elevación unilateral de piso de seno maxilar con ventana lateral utilizando xenoinjerto: reporte de caso / Unilateral elevation of maxillary sinus floor with lateral window using xenografts: report of a case

En maxilares atróficos la elevación de piso de seno es una práctica de alta predictibilidad. El adve- nimiento de materiales osteoconductores que generan andamiaje para la formación ósea propor- cionaron un aumento en la tasa de éxito de los implantes endoóseos. El presente artículo reporta un caso clínico en el cual se llevo a cabo un aumento del nivel de altura del piso de seno unila- teralmente por medio de la técnica de Cadwell- Luck modificada por Tatum, técnica con ventana lateral, donde se utilizó xenoinjerto óseo (OstiumMAX, implante de matriz ósea bovina, Laboratorio Bioxen) y membrana reabsorbible de colágeno( Laboratorio Bioxen) en el primer tiempo quirúrgi- co y seis meses después, en el segundo acto quirúrgico se colocaron tres implantes endoóseos (Sistema de implante dental TRP, Laboratorio Tormicron S.R.L.). Los resultados obtenidos fueron controlados en forma mediata y a distancia a través de radiografías panorámicas y tomografías computadas tipo Cone Beam, donde se midió la altura ósea generada post injerto. Pudo consta- tarse el éxito del procedimiento, basándonos en criterios clínico radiograficos de oseointegración (AU)

Quiste periapical: diagnóstico y tratamiento / Periapical cyst: diagnosis and treatment

Los quistes periapicales o radiculares representan una de las patologías periapicales más frecuentes dentro del grupo de las lesiones quísticas de los maxilares. Son el resultado de la extensión de proce- sos inflamatorios-infecciosos. Su diagnóstico sigue siendo un desafío para el profesional odontológico, quien debe diferenciarlo de otros procesos inflama- torios periapicales. El objetivo del presente artículo es presentar, apoyado en una revisión de la literatura, el caso clínico de un paciente masculino de 38 años de edad que se presentó a la consulta por leve tume- facción indolora en zona anterosuperior del maxilar. A la inspección se observó borramiento de la región del surco vestibular a nivel de piezas dentarias 1.1, 1.2 y 1.3, de color rojizo con crepitación de la tabla ósea vestibular a la palpación. La tomografía de haz cónico mostró lesión osteolítica, extendida desde zona apical de la pieza dentaria 1.4 hasta zona del elemento dentario 1.1. Se realizó la extirpación de la lesión y api- cectomía. El estudio histológico corroboró el diagnós- tico presuntivo de quiste periapical. Los controles a distancia mostraron buena evolución del tratamiento. Se concluyó en la importancia de realizar un correcto diagnóstico clínico e imagenológico para la selección de un adecuado tratamiento según el caso (AU)

Periapical or radicular cysts represent one of the most frequent periapical pathologies within the group of cystic lesions of the jaws. They are the result of the spread of inflammatory-infectious processes. Its diagnosis continues to be a challenge for the dentist, who must differentiate it from other periapical inflammatory processes. The objective of this article is to present, supported by a review of the literature, the clinical case of a 38-year-old male patient who presented to the consultation due to mild painless swelling in the anterosuperior maxilla. Upon inspection, effacement of the vestibular sulcus region was observed at the level of teeth 1.1, 1.2 and 1.3, reddish in color with crepitation of the buccal bone table on palpation. Cone beam tomography showed an osteolytic lesion that extended from the apical area of tooth 1.4 to area of tooth 1.1. Excision of the lesion and apicoectomy were performed. The histological study corroborated the presumptive diagnosis of periapical cyst. Remote controls showed a good evolution of the treatment. It was concluded on the importance of carrying out a correct clinical and imaging diagnosis for the selection of an adequate treatment according to the case (AU)

The retromandibular transparotid approach vs. retromandibular retroparotid approach for the mandibular condyle: our clinical experience

Aim: The mandible is regarded as a frequently fractured bone in patients who present with maxillofacial trauma accounting for almost 15.5% to 59% of all facial fractures. Managing condylar trauma has remained to be a point of contention amongst experts, regardless of the advances in surgical modalities and methodologies, and the treatment plan is often determined by the preference and the experience of the surgeon. There exist various approaches in the literature, each with its own specific benefits and drawbacks. With this study, we aimed to evaluate the prevalence of post-operative complications in patients who experienced ORIF by means of the retromandibular approach, by comparing the outcomes of one group having undergone transparotid surgery, with another that underwent retroparotid surgery. Methods: An experimental trial was undertaken. Convenience sampling was done from among the cases of condylar neck and base fracture visiting the department of OMFS, Dow University of Health Sciences from January 2017 to December 2019. An overall 26 patients were divided into 2 groups of 13 members each; one was managed using Open Reduction Internal Fixation (ORIF) by means of a retromandibular transparotid approach while the other group was treated with ORIF by means of a retromandibular retroparotid approach. A 6 month follow-up was done to assess range of active motion, occlusion, and complications such as deviation/deflection, neural injury, infections, sialocele, salivary fistulae and Frey's syndrome in both groups. Results: There was no statistically significant difference between the two groups in terms of inter-incisal opening, right and left lateral movements, or protrusion. One patient in the retroparotid group had deviation on mouth opening (7.69%), while one in the transparotid group reported with infection (7.69%), and 2 developed post operative seromas (15.38%). None had persisting facial nerve palsy at 6 months. Conclusion: We find no significant disparity between the 2 approaches at a follow-up of 6 months; therefore, the primary determining factor for selection of either technique is surgeon preference and appropriate case selection

Fratura condilar em paciente pediátrico: um relato de caso condilar / Fracture in pediatric patient: a case report

As fraturas faciais em crianças são raras, já que os ossos faciais pediátricos têm maior elasticidade, menos pneumatização, tecido adiposo circundante mais espesso e mais estabilização da mandíbula e maxila pelos dentes não irrompidos. Em geral, lesões nos tecidos moles são mais comuns em crianças do que fraturas esqueléticas. Entre as fraturas faciais pediátricas, as fraturas da mandíbula são as mais comuns, sendo o côndilo a área mais acometida em pacientes pediátricos. O côndilo é considerado o principal centro de crescimento da mandíbula em crianças, assim é de suma importância a definição do tratamento adequado, pautado em diversos critérios de avaliação, com o intuito de erradicar possíveis complicações advindas da fratura condilar. Assim o objetivo deste estudo é relatar um caso de fratura de côndilo unilateral em uma criança, na qual realizou-se abordagem cirúrgica com fixação interna, afim de elucidar e discutir as possíveis condutas terapêuticas acerca de tratamentos a serem aplicados, visto que esses ainda são bastante controversos na literatura e os resultados das diversas condutas são os mais diversos, apresentando variados aspectos que interferem na evolução dos pacientes(AU)

Facial fractures in children are rare, since pediatric facial bones have greater elasticity, less pneumatization,thicker surrounding adipose tissue and more stabilization of the jaw and jaw by unerupted teeth.In general, soft tissue injuries are more common in children than skeletal fractures.Among pediatric facial fractures, mandible fractures are the most common, with condyl being the most affected area in pediatric patients.The condyl is considered the main center of mandible growth in children, so it is of Paramount importance to define the appropriate treatment, based on several evaluationcriteria, in order to eradicate possible complications resulting from the condilar fracture.Thus, the aim of this study is to report a case of unilateral condyl fracture in a child, in which a surgical approach with internal fixation was performedin order to elucidate and discuss the possible therapeutic approaches about treatments to be applied, since these are still quite controversial in the literature and the results of the various behaviors are the most diverse,presenting several aspects that interfere in the evolution of patients(AU)
