Clinical signs of bruxism in CrossFit® practitioners: observational study.

INTRODUCTION: CrossFit® is a physical training method that aims to promote physical fitness through the development of components such as aerobic capacity, strength and muscular endurance. Data regarding bruxism behaviors in CrossFit® practitioners are scarce, but previous studies have shown increased dental clenching behavior during weightlifting practices. OBJECTIVE: The present study aimed to evaluate clinical signs of bruxism in CrossFit® practitioners. METHODS: The sample comprised a convenience sample of CrossFit® practitioners (n=57), of both genders, aged 19-58 years. Outcome variables were as follows: Oral Behavior Checklist, the International Physical Activity Questionnaire and the Standardized Tool for the Assessment of Bruxism. Data were expressed in terms of absolute values and percentages. Spearman's correlation and Fisher exact tests were used for statistical analysis, and a significance level of 5% was considered. RESULTS: The mean age was 32.82 years, with a female majority (63.15%). CrossFit® practitioners frequently reported clenching their teeth during training practice (61.40%) and presented linea alba (82.45%), lip impression (54.38%), tongue impression (26.31%), bone exostosis (19.29%), tooth wear (61.40%) and non-carious cervical lesions (35.09%). CONCLUSIONS: No correlation was found between clinical signs of bruxism, oral behaviors and physical activity intensity; however, the results suggest that individuals who practice CrossFit® training have oral behaviors that can cause morpho-functional changes in the stomatognathic system, especially the habit of clenching their teeth during training. In addition, data emphasize the need for dental health education among CrossFit® practitioners, and more studies with a representative sample are necessary.

Endoscopic Calcaneoplasty in Haglund Disease: Surgical Technique, Clinical and Subjective Outcomes.

BACKGROUND: During the last decade, arthroscopic procedures have been replacing open techniques in Haglund disease treatment because of their considerable advantages. Endoscopic calcaneoplasty is a technique that allows resection of posterosuperior calcaneal exostosis and retrocalcaneal bursitis. The objective of this article was to describe this technique and report its clinical and subjective outcome. METHODS: A retrospective study was performed of consecutive patients undergoing endoscopic Haglund resection surgery between July 2014 and March 2020 at a single academic institution. All patients were surveyed in person about the level of pain (visual analog scale), its location (central, lateral, medial or diffuse), its relation with rest, or physical activity. Clinical evaluation was assessed using the hindfoot scale designed by the American Orthopaedic Foot & Ankle Society (AOFAS). RESULTS: In this study, 14 endoscopic calcaneoplasties were performed in 14 patients, with an average follow-up of 40 months. The visual analog scale score improved from a preoperative average value of 9.07 to 1.8 after surgery (P > .0001). The AOFAS scale rose from 38.7 before surgery to 94.6 postoperative (P > .0001). Good subjective results were observed in 12 patients (85.7%), and all of them would have surgery again. There were no wound complications or infections. No patient required reoperation. CONCLUSION: In this relatively small cohort, we found that endoscopic calcaneoplasty was associated with good clinical and subjective results with few complications.

Cirugía preprotésica de torus mandibular bilateral con impedimento del movimiento lingual / Preprosthetic surgery of a bilateral mandibular torus with tongue movement dysfunction

El torus mandibular es un crecimiento exofítico óseo benigno en la parte interna de la mandíbula, generalmente presente en ambos lados. Su etiología se relaciona a diversos factores como la herencia, grado de estrés, factores ambientales, nutricionales y trauma oclusal. Puede causar problemas funcionales y estéticos, como dificultad en la pronunciación, mal aliento, molestias al comer con prótesis mal adaptadas y ulceraciones. En la mayoría de los casos no es necesario el tratamiento, excepto cuando se requiere para mejorar la función protésica o solucionar problemas funcionales. En este artículo presentamos la situación clínica que describe la escisión exitosa del torus mandibular bilateral en un paciente de 57 años para la posterior rehabilitación protésica. La escisión del torus mandibular bilateral es un procedimiento seguro y predecible que ayuda a prevenir complicaciones protésicas y biológicas, mejorando la estabilidad y la función del sistema estomatognático (AU)

The mandibular torus is a benign bony exophytic growth in the inner part of the mandible, usually present on both sides. Its etiology is related to various factors such as heredity, degree of stress, environmental and nutritional factors, and occlusal trauma. It can cause functional and aesthetic problems, such as difficulty in pronunciation, bad breath, discomfort when eating with ill-fitting prostheses, and ulcerations. In most cases, treatment is not necessary, except when it is required to improve prosthetic function or solve functional problems. In this article we present the clinical situation that describes the successful excision of the bilateral mandibular torus in a 57-year-old patient for subsequent prosthetic rehabilitation. Bilateral mandibular torus excision is a safe and predictable procedure that helps prevent prosthetic and biological complications, improving the stability and function of the stomatognathic system (AU)

Osteocondroma en una localización atípica. Reporte de Caso / Osteochondroma in an atypical location. Case report

INTRODUCCIÓN. Los osteocondromas son considerados como el tumor benigno más común entre los de origen óseo, se denomina también exostosis, y se lo define por la Organización Mundial de la Salud como una proyección ósea cubierta de una capa cartilaginosa en la superficie externa. Representa el 20-50% de todos los tumores benignos óseos. Se diagnostica en su mayoría en pacientes pediátricos. RESULTADOS. Presentamos el caso de una paciente de 8 años con osteocondroma único en escápula de aparición espontánea, sin otras lesiones en el cuerpo. DISCUSIÓN. Los lugares comunes de aparición de osteocondromas son los huesos largos con placa de crecimiento o metáfisis, localizaciones raras como la escapula comprenden menos del 1%. El tratamiento es expectante y al momento de producirse síntomas, está indicado la excision quirúrgica. CONCLUSIÓN. La enfermedad tiene un curso benigno sin complicaciones cuando se trata de un tumor esporádico, en los síndormes de exostosis, las recurrencias y riesgo de malignidad hacen necesario un seguimiento más cercano.

INTRODUCTION. Osteochondromas are considered the most common benign tumor among those of bone origin, it is also called exostosis, and is considered by the World Health Organization as a bone projection covered with a cartilaginous layer on the external surface), it represents 20­50% of all benign tumors and is mostly diagnosed in pediatric patients. RESULTS. We present the case of an 8-year-old female with a single osteochondroma in the scapula of spontaneous appearance, without other lesions in the body. DISCUSSION: The common places of appearance are long bones with a growth plate or metaphysis, rare locations such as the scapula comprise less than 1%. The treatment is expectant, and when symptoms occur, surgical excision is indicated. CONCLUSION: The disease has a benign course without complications when it is a sporadic tumor, in exostosis syndromes the recurrences and risk of malignancy make closer follow-up necessary.

Medication-related osteonecrosis in torus palatinus: Report of a case and literature review.

BACKGROUND: Medication-related osteonecrosis of the jaw bones have been frequently reported. However, its occurrence in torus palatinus is very rare with only 10 cases published in the English-language literature. CASE REPORT: We describe an additional case in a 79-year-old woman, who was referred for evaluation of a painful swelling with areas of suppuration on the hard palate. CONCLUSION: Conservative treatment was performed and after spontaneous sequestrectomy, total healing was achieved.

Introduction.The external occipital protuberance (EOP) is a smooth convex surface which commonly does not present any type of irregularities. The development of an enthesophyte in young population has attracted the attention of researchers. Objective.To determine the prevalence, size, age, and sex of individuals with bony projections that resembles a hook developed in EOP. Methodology.Descriptive observational study. 5065 lateral skull x-rays were observed. 4017 fulfilled all the criteria. The x-rays were reviewed for the presence of a bony excrescence in EOP, and they were measured. Results. From a both sexes population between 13 to 45 years old 2902 were female and 1115 were male. 67% X-rays presented the enthesophyte ranging from 5 ­24mm in length. 511 out of 1667 had an enthesophyte at or above 5 mm. There were 903 patients with an enthesophyte ranging from 9 ­12 mm in length and 254 had the protuberance ranging from 13 ­24 mm. Statistically significant range of 68% vs 32% between males and females were observed. From individuals of 40 years and above, just 1 male patient out of 32 showedthe enthesophyte. Conclusion.Significant association with the development of a bony protuberance at the POE in young and young adult male population has been found. This is the first study of this type in Paraguayan individuals. To expand the field of studies, future research is needed to better examine and understand the reason forthe development of this bony excrescence.

Prevalencia de la exóstosis del conducto auditivo externo entre practicantes de surf y bodyboard en la costa central de Chile / Prevalence of auditory canal exostosis among surfers and bodyboarding athletes of the central Chilean coast

La exóstosis del conducto auditivo externo (ECAE), también conocida como oído de surfista, es una alteración del tejido óseo del oído externo, principalmente causada debido a la sobrexposición al frío. Considerando que los practicantes de deportes acuáticos como el surf y bodyboard de las costas del pacífico sur se exponen a aguas con temperaturas entre 12-16 °C, se busca determinar, en este estudio, la prevalencia y grado de ECAE en practicantes de surf y bodyboard de las localidades de Reñaca y Concón durante el año 2018. Se realizó una evaluación del CAE mediante video-otoscopía a 67 personas (134 oídos) practicantes de surf y bodyboard de las playas de Reñaca y Concón, y se les aplicó un cuestionario respecto a sus hábitos de práctica. Como resultado, se observó una prevalencia de ECAE del 77,6%, siendo el 61,2% ECAE bilateral y el 16,4% ECAE unilateral. Se pudo determinar, además, que el 62,3%de los participantes no usa protecciones. A partir de estos hallazgos, es posible concluir que existe una alta prevalencia de la ECAE en practicantes de surf y bodyboard en las costas centrales chilenas, lo que debería alertar tanto a la población practicante como a profesionales de la salud auditiva con el fin de promover una vida saludable en esta población.

External auditory canal exostosis (ECAE), also known as surfer's ear, is an alteration of the bone tissue of the external ear, mainly caused due to overexposure to cold. Considering that those who practice water sports such as surfing and bodyboarding on the Pacific coast are exposed to waters with temperatures between 12-16 °C,. We seek to determine, in this study, the prevalence and degree of ECAE in surfers and bodyboarders from the coast of the south of Pacific Ocean, Reñaca and Concón, during the year 2018. An evaluation of the ECAE was carried out by means of video-otoscopy in 67 people (134 ears) who practiced surfing and bodyboarding from the beaches of Reñaca and Concón, and a questionnaire was used to collect information about their practice habits. As a result, a prevalence of ECAE of 77.6% was observed, with 61.2% bilateral ECAE and 16.4% unilateral ECAE. It was also possible to determine that 62.3% of the participants do not use protections. Based on these findings, it is possible to conclude that there is a high prevalence of ECAE in surfers and bodyboarders on the central Chilean coasts, which should alert both the practicing population and hearing health professionals to promote a healthy life in this population.

Torus mandibular e palatino predisponentes em um grupo familiar: fatores genéticos e ambientais, relato de uma série de casos / Mandibular and palatine torus predisposing in a family group: genetic and environmental factors, report of a series of cases / Torus mandibular y palatino predisponente en un grupo familiar: factores genéticos y ambientales, informe de una serie de casos

As exostoses mais conhecidas são o Torus palatino e mandibular, que se desenvolvem a partir do crescimento benigno da cortical óssea, localizadas respectivamente na linha média palatina e superfície lingual de caninos e pré-molares, podendo ser unilaterais ou bilaterais. Esse trabalho tem como objetivo o estudo de um grupo familiar que apresentaram o Torus como característica em comum, buscando confirmar a presença e prevalência das características clínicas multifatoriais listadas na literatura, possibilitando o diagnóstico da etiologia e assim traçando um plano de tratamento individual, se necessário. Como metodologia, foi realizada uma triagem com cada membro familiar na clínica Odontológica da Faculdade Sete Lagoas - FACSETE, descartando a participação no estudo os membros que não apresentaram o Torus. Os indivíduos que apresentaram indicação da remoção cirúrgica foram encaminhados para clínica de cirurgia da própria instituição. Concluímos, portanto, com este estudo que fatores genéticos e ambientais colaboram como fator etiológico mais predominantes para surgimento do Torus no grupo familiar estudado... (AU)

The best known exostosis are the palatine and mandibular Torus, which develop from the benign growth of the cortical bone, located respectively in the midpalatal line and lingual surface of canines and premolars, and maybe unilateral or bilateral. This work aims to study a family group that had Torus as a common feature, confirming the presence and prevalence of multifactorial clinical features listed in the literature, enabling the diagnosis of etiology and thus outlining an in dividual treatment plan, if necessary. As a methodology, a screening was performed by each family member at the Dental Clinic of Facul dade Sete Lagoas - FACSETE, discarding the participation in the study for members who did not present Torus. Individuals who indicated surgical removal were referred to the institution's own surgery clinic. Therefore, we conclude with this study that genetic and environmental factors collaborate as the most predominant etiological factor for the emergence of Torus in the studied family group... (AU)

Las exostosis más conocidas son el Torus palatino y el Torus mandibular, las cuales se desarrollan a partir del crecimiento benigno del hueso cortical y están ubicadas respectivamente en la línea medio palatina y en la cara lingual de los caninos y de los premolares que pueden ser unilaterales o bilaterales. Este proyecto tiene como objetivo el estudio de un grupo familiar que presentó en sus características comunes el Torus, buscando confirmar la presencia y el predominio de las características clínicas multifactoriales listadas en la literatura, lo que hizo posible el diagnóstico de la etiología y diseñar un plan de tratamiento individual, caso necesiten. Como la metodología fue hecho una selección con los miembros de la familia en la clínica odontologica de la Faculdade Sete Lagoas - FACSETE, quitando de los estudios las personas de la familia que no presentaron el Torus. Los individuos que presentaron indicación de extirpación quirúrgica fueron enviados a la clínica de cirugía de la escuela. Concluimos con este estudio que los factores genéticos y ambientales colaboraron como los factores etiológicos más predominantes para la aparición del Torus en la familia analizada... (AU)

Unusual complications at the recipient site following periodontal plastic surgery procedures: a systematic review.

OBJECTIVE: To identify and describe unusual soft tissue complications of periodontal plastic surgery procedures at the recipient site after periodontal grafts. MATERIALS AND METHODS: Two independent reviewers performed a comprehensive search in MEDLINE, Cochrane, periodontics journals, reference lists, and grey literature for articles dated up to July 2021. Publications related to surgical interventions only around the teeth with an unusual complication at the recipient site were selected. No restrictions were made in the number of cases, follow-up period, or language. The Cochrane Collaboration's tool for assessing risk of bias, the Newcastle-Ottawa Scale (NOS), and two validated case report/series checklists were used to critically appraise the studies. RESULTS: A total of 1434 articles were examined, of which 28 met the inclusion criteria: one RCT, two cohort studies, and twenty-five case reports/series. The periodontal plastic surgery procedures described in these articles were conducted to treat lack of attached gingiva and gingival recessions. The following unusual complications were found: bone exostosis, epithelial inclusion, root resorption, abscess, overgrowth, "liver clot" formation, and oroantral communication. CONCLUSION: Bone exostosis and epithelial inclusions were the most prevalent unusual complications following treatment with subepithelial connective tissue graft, free gingival graft, and acellular dermal matrix allograft. Due to the nature of the reports, the clinical recommendations for diagnosis and treatment cannot be homogenized. Clinical studies reporting complications are required to develop management protocols (PROSPERO CRD42021230875). CLINICAL RELEVANCE: Clinicians need to know the main complications that can occur in mucogingival surgeries as well as their clinical management to provide a successful and predictable treatment.

Diagnóstico e manejo das exostoses maxilares: relato de caso / Diagnosis and management of maxillary exostoses: case report

As exostoses maxilares são protuberâncias ósseas de caráter benigno, que se originam da cortical óssea e de etiologia controversa. Sua denominação vai depender da localização anatômica em que se encontra. Podem interferir na mastigação, fonação e adaptação de próteses removíveis parciais ou totais, devendo sua remoção ser considerada. O intuito deste trabalho é relatar o manejo de uma paciente com exostoses vestibulares em maxila e realizar uma breve revisão de literatura.

Maxillary exostoses are benign bony protuberances, which originate from the cortical bone and of controversial etiology. Its denomination will depend on its anatomical location. They can interfere with chewing, phonation and adaptation of partial or total removable prostheses, and their removal should be considered. The aim of this work is to report the management of a patient with vestibular exostosis in the maxilla and perform a brief literature review.

Technique Tip: Medial prominence bone spur resection in the third-generation percutaneous Chevron-Akin Osteotomy Technique (PECA) for hallux valgus correction.

The third-generation percutaneous chevron and Akin osteotomy (PECA) technique for surgical management of hallux valgus has shown improvement in clinical and radiographic outcomes. During this procedure, lateral translation and fixation of the first metatarsal head results in the formation of a bony prominence on the medial side of the distal aspect of the first metatarsal which can cause pain and discomfort to the patient. We describe two techniques to address this bony prominence; either i) excision osteotomy and removal of the fragment or ii) a dorsal closing wedge osteotomy retaining the bony fragment. LEVEL OF EVIDENCE: Level V, expert opinion.

Variability of exostoses on human jaws during the past six millennia in Northern China / Variabilidad de las exostosis en las mandíbulas humanas durante los últimos seis milenios en el norte de China

SUMMARY: The aim of this study was to survey oral exostoses in human populations that belonged to the same region encompassing five periods over 6000 years, to determine the prevalence and its changing trend over time. A total of 306 human jaws belonging to the modern Xi'an region and four archeological sites, Banpo (6700-5600 years BP), Shaolingyuan (3000 years BP), Shanren (2200 years BP) and Chang'an (1000-1300 years BP), were investigated. The degree of buccal exostosis (BE), torus mandibularis (TM) and torus palatinus (TP) and the TP shape were recorded. The prevalence of BE, TM, and TP in the five groups was 20.8 %-62.5 %, 17.5 %-71.5 %, and 31.7 %-74.2 %, respectively. The differences in the three types of exostoses among the five groups were all statistically significant, but only TM and TP showed a decreasing trend over time. A high and quite diverse prevalence of oral exostoses was found in the five groups of samples. Decreasing trends in relation to time for TM and TP were detected.

RESUMEN: El objetivo de este estudio fue sondear las exostosis orales en poblaciones humanas que pertenecían a la misma región abarcando cinco períodos durante 6000 años, para determinar la prevalencia y su tendencia cambiante a lo largo del tiempo. Un total de 306 mandíbulas humanas pertenecientes a la moderna región de Xi'an y cuatro sitios arqueológicos, Banpo (6700-5600 años AP), Shaolingyuan (3000 años AP), Shanren (2200 años AP) y Chang'an (1000-1300 años AP) BP), fueron investigados. Se registró el grado de exostosis bucal (EO), torus mandibular (TM) y torus palatino (TP) y la forma de TP. La prevalencia de EO, TM y TP en los cinco grupos fue 20,8 % -62,5 %, 17,5 % -71,5 % y 31,7 % -74,2 %, respectivamente. Las diferencias en los tres tipos de exostosis entre los cinco grupos fueron todas estadísticamente significativas, pero solo TM y TP mostraron una tendencia decreciente con el tiempo. Se encontró una prevalencia alta y bastante diversa de exostosis oral en los cinco grupos de muestras. Se detectaron tendencias decrecientes en relación al tiempo para TM y TP.

Morphometric analysis of the mandibular fossa in dentate and edentulous patients: A cone beam computed tomography study.

STATEMENT OF PROBLEM: Mandibular fossa roof thickness and lateral inclination could be associated with the presence of bone changes in the mandibular condyle in dentate and edentulous patients. However, literature regarding the relationship between the presence and absence of teeth and the morphologic features of the temporomandibular joint is lacking. This knowledge could provide a better understanding of changes affecting the correct functioning of the stomatognathic system. PURPOSE: The purpose of this clinical study was to assess the mandibular fossa roof thickness and lateral inclination in relation to sex, presence or absence of teeth, and bone changes in the mandibular condyle through cone beam computed tomography (CBCT). MATERIAL AND METHODS: CBCT scans of 100 individuals (50 dentate and 50 edentulous) were evaluated in terms of mandibular fossa roof thickness and lateral inclination. Bone changes in the mandibular condyle were classified dichotomously in relation to osteophytes, erosion, sclerosis, and flattening. Differences were assessed with the Student t test, the chi-square test, and 2-way analysis of variance (ANOVA), with Tukey post hoc tests (α=.05). RESULTS: Sex was not related to mandibular fossa measurements. Edentulous participants showed a higher mandibular fossa lateral inclination (P<.001) and lower roof thickness (P=.001) than dentate participants. When the association between bone changes in the mandibular condyle was evaluated in dentate and edentulous groups, only sclerosis showed a statistically significant association (P<.001). The 2-way ANOVA showed that the mandibular fossa roof thickness was lower in edentulous participants in the presence of flattening and erosion and that the mandibular fossa lateral inclination was higher in the presence of osteophytes, erosion, and sclerosis (P<.001). Among dentate participants, the mandibular fossa lateral inclination was higher in the presence of flattening (P=.024). CONCLUSIONS: Mandibular fossa roof thickness and lateral inclination are not associated with sex. However, tooth absence and bone changes in the mandibular condyle are related to mandibular fossa measurements.

Evaluation of oral stereognosis in completely edentulous patients with palatal tori / Evaluación de la estereognosia oral en pacientes completamente edéntulos con toros palatinos

Background: The corollary is not investigated in the completely edentulous patients with palatal tori. Objective: The aim of this study was to assess the oral stereognostic ability in completely edentulous patients with palatal tori. Material and Methods: Thirty-four completely edentulous patients aged 50 to 89 years were allocated to Group 1 (without palatal tori, n=18) and Group 2 (with palatal tori, n=16). The oral stereognostic test was conducted using 6 intraoral test pieces (circle/square/rectangle/triangle/plus/toroid) that were fabricated to standard dimensions using the light cure acrylic resin. Each test piece was placed in the patient's mouth and was asked to manipulate the test piece between the tongue and the palate. The patients identified the shapes by matching them on a shape chart. Each correct identification was assigned a score of 1. The response time taken to identify each shape was recorded. Statistical computation was done using a chi - square test and Mann-Whitney U test. Results: Significant difference was observed in the overall scoring percentages between the 2 groups (p<0.05). Group 2 had lower oral stereognostic scores compared to group 1 (p<0.05). There was no statistically significant difference in the mean response time for identifying the shapes among the groups, however group 2 patients had longer response time. Conclusion: Oral stereognostic ability of the completely edentulous patients with torus palatinus was lower when compared to completely edentulous patients without tori.

Antecedentes: el corolario no se investiga en los pacientes completamente desdentados con toros palatinos. Objetivo:El objetivo de este estudio fue evaluar la capacidad estereognóstica oral en pacientes completamente edéntulos con toros palatinos. Material y Métodos: Treinta y cuatro pacientes completamente edéntulos de 50 a 89 años fueron asignados al Grupo 1 (sin toros palatinos, n = 18) y al Grupo 2 (con toros palatinos, n = 16). La prueba estereognóstica oral se realizó utilizando 6 piezas de prueba intraorales (círculo / cuadrado / rectángulo / triángulo / cruz / aro) que se fabricaron a dimensiones estándar utilizando la resina acrílica fotopolimerizable. Cada pieza de prueba se colocó en la boca del paciente y se le pidió que manipulara la pieza de prueba entre la lengua y el paladar. Los pacientes identificaron las formas haciéndolas coincidir en un gráfico de formas. A cada identificación correcta se le asignó una puntuación de 1. Se registró el tiempo de respuesta necesario para identificar cada forma. El cálculo estadístico se realizó mediante la prueba de chi-cuadrado y la prueba U de Mann-Whitney. Resultados: Se observó una diferencia significativa en los porcentajes de puntuación generales entre los 2 grupos (p<0,05). El grupo 2 tuvo puntuaciones estereognósticas orales más bajas en comparación con el grupo 1 (p<0,05). No hubo diferencia estadísticamente significativa en el tiempo medio de respuesta para identificar las formas entre los grupos, sin embargo, los pacientes del grupo 2 tuvieron un tiempo de respuesta más largo.Conclusión: La capacidad estereognóstica oral de los pacientes completamente edéntulos con torus palatino fue menor en comparación con los pacientes completamente edéntulos sin torus.

Escisión de torus mandibular bilateral en paciente sistémicamente comprometido: reporte de caso / Excision of bilateral mandibular torus in a systemically com-promised patient: a case report

Introducción: El torus mandibular es un crecimiento exofítico óseo ubicado en el área lingual de la mandíbula, generalmente bilateral. Puede estar asociado con trastornos temporomandibulares, afectar la pronunciación, producir halitosis, interferir con la deglución y causar dolor en la mucosa cuando está bajo prótesis mal diseñadas. Normalmente, el tratamiento no es necesario, excepto por necesidades protésicas, problemas funcionales, retención de alimentos, trastornos fonéticos o en caso de que se vaya a usar como injerto óseo autólogo. El objetivo de este reporte de caso fue realizar la escisión del torus mandibular bilateral en un paciente sistémicamente comprometido para su posterior rehabilitación con una prótesis parcial removible. Se realizo la atención de una paciente de 66 años sexo femenino, a quien, luego de analizar los medios diagnósticos y la evidencia científica, se le pudo realizar la escisión del torus mandibular bilateral de forma atraumática; esto permitió el correcto asentamiento de una prótesis parcial removible. La escisión del torus mandibular bilateral es un procedimiento seguro y predecible, y ayuda a evitar complicaciones protésicas, como el diseño de la estructura, y biológicas, como úlceras, depósitos de comida o halitosis, lo que devuelve la estabilidad y la función al sistema estomatognático. (AU)

The mandibular torus is a bony exophytic growth located in the lingual area of the mandible. While this growth is generally bilateral, it can be associated with temporomandibular disorders. I It affects pronunciation, produces halitosis, interferes with swallowing, and causes pain in the mucosa under poorly designed prostheses. Normally, treatment is not necessary, except in cases with prosthetic needs, functional problems, food retention, phonetic disorders or if it is to be used as an autologous bone graft. The aim of this study was to perform a bilateral mandibular torus excision in a systemically compromised patient for subsequent rehabilitation with a removable partial denture. A 66-year-old female presenting a bilateral mandibular torus attended our dental clinic. After achieving the diagnosis and analyzing the scientific evidence available, the bilateral mandibular torus was atraumatically excised, allowing correct seating of a removable partial denture. Bilateral mandibular torus excision is a safe and effective procedure, which helps to avoid prosthetic complications involving structural design and biological complications such as ulcers, food deposits and / or halitosis, restoring stability and function to the stomatognathic system.

Exostose palatina aberrante / Exostosis palatina aberrante / Aberrant palatal exostosis

RESUMO Introdução: Exostose é um crescimento ósseo benigno que comumente acomete a mandíbula e a maxila, porém raramente apresenta grandes dimensões. Objetivo: Descrever um caso de exostose palatina de apresentação rara e discutir os principais aspectos clínicos envolvidos. Relato de caso: Paciente, gênero masculino, 66 anos, melanoderma, com história de aumento de volume no palato duro com tempo de evolução indeterminado, sem queixas álgicas, porém relatava transtornos de mastigação e fonação. O conjunto da lesão obliterava toda a profundidade do palato e ocupava grande volume na cavidade oral. A Tomografia Computadorizada de Feixe Cônico demonstrava áreas bem corticalizadas na superfície da lesão e áreas centrais menos hiperdensas, compatíveis com osso medular maduro. Após exames e pareceres pós-operatórios o paciente foi submetido a tratamento cirúrgico sob anestesia geral para remoção da massa óssea e osteoplastia subjacente, a fim de dar contornos normais ao palato, e o material colhido foi enviado para a biópsia que estabeleceu o diagnóstico de exostose. O paciente evoluiu sem complicações. Conclusão: Embora a exostose seja um crescimento ósseo benigno, ela causou problemas funcionais ao paciente, necessitando assim de um tratamento cirúrgico. Após três meses da remoção, os distúrbios foram revertidos à normalidade, e a sua reabilitação protética está em andamento(AU)

ABSTRACT Introduction: Exostosis is a benign bone growth that commonly affects the jaw and maxilla, but is rarely large. Objective: Describe a case of rare palatal exostosis and discuss the main clinical aspects involved. Case presentation: A case is presented of a male 66-year-old dark-skin patient with a history of hard palate enlargement of an indefinite time of evolution, and chewing and phonation disorders. The lesions had obliterated the entire palatal depth and occupied a large section of the oral cavity. Cone beam computed tomography revealed corticalized areas on the surface of the lesion and less hyperdense central areas compatible with mature bone marrow. After preoperative examination and advice, the patient underwent surgical treatment under general anesthesia to remove the bone mass and underlying osteoplasty to obtain normal palatal contours. The material collected was sent for biopsy testing, which established the diagnosis of exostosis. The patient recovered without any complications. Conclusions: Although exostosis is a benign bone growth, in this case it caused functional problems to the patient, thus requiring surgical treatment. Three months after removal, the disorders have been reverted to normal and prosthetic rehabilitation is underway(AU)

Exérese de extenso tórus palatino: relato de caso / Excision of extensive palatine torus: case report

Introdução: O tórus palatino se caracteriza por um desenvolvimento ósseo não patológico que ocorre ao longo da linha média do palato duro. Possui etiologia relacionada a fatores genéticos e ambientais, sendo a exostose mais comum em cavidade oral. O tratamento cirúrgico só é necessário em casos específicos quando o tórus interfere nas funções do sistema estomatognático ou na instalação de prótese total no palato. O presente estudo teve como objetivo relatar um caso clínico de tratamento cirúrgico de extenso tórus palatino onde foi empregado um acesso cirúrgico modificado. Relato de caso: Esse trabalho descreve o caso de uma paciente com um tórus palatino de dimensões atípicas com queixas fonéticas e protéticas. Devido ao tamanho da exostose e para permitir uma abordagem mais simplificada, optou-se por um acesso cirúrgico modificado, que em conjunto com a confecção de placa em resina acrílica para instalação no pós-operatório, auxiliou na recuperação e conforto da paciente.

Exostose palatina bilateral em bebê / Exostosis palatina bilateral en bebé / Bilateral palatal exostosis in an infant

RESUMO Introdução: As exostoses são definidas como protuberâncias ósseas localizadas, de caráter benigno, sendo uma rara patologia em bebês. Objetivo: Relatar um caso de exostose palatina bilateral em um bebê melanoderma do sexo feminino de 1 ano e 4 meses de idade. Relato de caso: A criança compareceu a Clínica Escola de Odontopediatria, acompanhada de sua mãe, para avaliação odontológica. Durante a anamnese, o responsável queixou-se de atraso na irrupção dos dentes decíduos e presença de protuberância na arcada superior, sem sintomatologia dolorosa. Foi relatado que três membros da família também apresentavam essa mesma alteração na maxila ou mandíbula, possivelmente sugerindo um componente genético. Ao exame clínico intrabucal, verificou-se um aumento de volume ósseo bilateral plano localizado na maxila, na região lingual das tuberosidades palatinas, recoberto por mucosa bucal normal. A superfície era rígida à palpação e com bordas claramente definidas. O componente genético foi associado ao aspecto clínico da lesão, bem como o sexo e a etnia. O diagnóstico estabelecido foi exostose palatina bilateral. A biópsia e o tratamento ativo para remoção da patologia não se justificaram devido à pouca idade da criança, ausência de sintomatologia dolorosa e de interferências na alimentação, deglutição ou outra função bucal. A paciente foi acompanhada periodicamente e apresentou sequência de irrupção dos dentes decíduos normal. Conclusão: Embora a exostose palatina apresente baixa prevalência em crianças, é importante que o cirurgião-dentista tenha conhecimento para realizar seu correto diagnóstico e plano de tratamento(AU)

RESUMEN Introducción: Las exostosis son definidas como bultos óseos, de carácter benigno, y contituyen una infrecuente afección en bebés. Objetivo: Describir un caso de exostosis palatina bilateral en un bebé melanoderma del sexo femenino de 1 año y 4 meses de edad.

Conclusiones: Aunque la exostosis palatina sea infrecuente en niños, es importante que el cirujano dentista tenga conocimiento para realizar el correcto diagnóstico y el plan de tratamiento(AU)

ABSTRACT Introduction: Exostoses are localized bony lumps of a benign nature. They are an infrequent condition in infants. Objective: Present a case of bilateral palatal exostosis in a dark-skinned female infant aged one year and four months. Case presentation: The girl was brought by her mother to the Children's Dental Clinic for oral examination. During anamnesis, the mother referred to delay in the eruption of deciduous teeth and the presence of lumps on the upper arch without any painful symptom. She also reported that three relatives had the same alteration in their maxilla or mandible. Oral examination revealed a bilateral flat bony lump in the maxilla, in the lingual region of the palatal tuberosities, covered by normal oral mucosa. The surface was stiff to palpation with well defined borders. The genetic factor was associated to the clinical aspect of the lesion, as well as the sex and ethnicity of the patient. The diagnosis was bilateral palatal exostosis. Biopsy and active treatment for removal of the lesion were not justified due to the patient's age, absence of painful symptoms, and potential interference with feeding, swallowing and other oral functions. The patient was periodically followed-up and was observed to present a normal process of deciduous tooth eruption. Conclusions: Even though palatal exostosis is infrequent in children, it is important for dental surgeons to be knowledgeable about the topic so as to reach an appropriate diagnosis and treatment plan(AU)
