ABSTRACT

Introdução: O adenoma pleomórfico (AP) é a neoplasia de glândula salivar mais comum e se apresenta como um aumento de superfície firme, indolor e com crescimento lento. O palato, a cavidade nasal e a nasofaringe são áreas em que se localizam muitas glândulas salivares menores, sendo o adenoma pleomórfico, o tumor benigno mais comum nessas glândulas. O AP pode acometer indivíduos em qualquer faixa etária, principalmente na terceira e quarta década de vida, com predominância pelo gênero feminino. O artigo objetiva relatar um caso clínico de adenoma pleomórfico em palato duro, comparando com dados presentes na literatura especializada em relação, especialmente, aos sítios acometidos e as formas de tratamentos existentes. Relato de caso: Paciente do sexo feminino, 34 anos, compareceu ao ambulatório do HU-Univasf com queixa de aumento de volume indolor em boca há 02 anos. Foi realizada uma biópsia incisional onde no exame histopatológico foi diagnosticado como Adenoma Pleomórfico. O tratamento eleito foi a excisão cirúrgica e uso de placa de polimetilmetacrilato no pós-operatório. Atualmente o paciente apresenta follow up de 02 anos e 05 meses, sem sinais de recidiva da lesão e sem queixas locais... (AU)

ABSTRACT

Introducción: El movimiento corporal, obedece y produce actividad del músculo esquelético para lo cual debe existir un equilibrio muscular estático, a partir del cual se genere el desplazamiento de los elementos anatómicos, involucrados en él, ya sea como respuesta a la volición o a la percepción inconsciente al estímulo que lo demande. Objetivo: Asociar el comportamiento morfológico del hioides con ciertas variables morfológicas del viscerocráneo de esqueletos (excepto la mandíbula). Material y Métodos: Se realizó estudio osteológico en una muestra ósea de 82 esqueletos mediante mediciones morfométricas del hueso hioides y huesos del viscerocráneo. Se utilizaron matrices de coeficiente de correlación lineal de Pearson en SPSS 22 para evaluar la relación de la morfología del hioides con respecto a la morfología de los huesos de la cara. Variables morfológicas del viscerocráneo como ancho bicigomático (abc), ancho transversal externo del paladar óseo (pote), ancho sagital externo del paladar óseo (pose) y la altura del tercio medio de la cara (tmed). Resultados: Se obtuvo una gran correlación positiva y significativa de distintas variables morfológicas del hioides, -tanto de su cuerpo como de sus astas o cuernos mayores- con las variables morfológicas del viscerocráneo. Conclusiones: Se corrobora la asociación de la morfología del hueso hioides con el crecimiento de los huesos del viscerocráneo(AU)


Introduction: Body movement obeys and produces activity in the skeletal muscle for which there must be a static muscle equilibrium that produces the movement of the anatomic elements involved in it, either as a result of volition or as the unconscious perception of a stimulus. Objective: To associate the morphological behavior of the hyoid bone with some morphological variables of the viscerocranium of skeletons (except the jaw). Material and Methods: An osteological study was carried out in a bone sample of 82 skulls by performing morphometric measurements of the hyoid bone and the bones of the viscerocranium. Pearson's correlation coefficient and SPSS Version 22 were used to evaluate the relationship between the morphology of the hyoid bone and the facial bones. Morphological variables of the viscerocranium include: bizygomatic width (BW), external transverse width of the hard palate (ETWHP), external sagittal width of the hard palate (ESWHP), and the height of the middle third of the face (MTF). Results: A very strong positive correlation between different morphological variables of the hyoid bone, -both at the level of its antlers or greater horns- and the morphological variables of the viscerocranium was obtained. Conclusions: These findings corroborate the association between the hyoid bone and the growth of facial bones(AU)

ABSTRACT

Introdução: O cisto do ducto nasopalatino é uma lesão não odontogênica com etiologia controversa. No entanto, fatores irritantes, como trauma local e infecções bacterianas, podem estimular o remanescente epitelial do ducto nasopalatino, levando a uma formação cística. Sua predileção ocorre em homens adultos entre a quarta e a sexta décadas. Geralmente é assintomático, sendo detectado por exame de rotina. O objetivo do presente estudo é apresentar e discutir um caso de cisto do Ducto Nasopalatino, analisando-se os aspectos clínicos e imaginológicos da patologia em face, comparando-o com dados provenientes da literatura corrente. Relato de caso: Como resultado este artigo apresenta a abordagem de um caso cirúrgico de cisto do Ducto Nasopalatino em face, assintomático, descoberto em exame imaginológico de rotina, biopsiado e enucleado cirurgicamente, com acompanhamento de 5 anos sem recidiva. Considerações finais: É evidente, portanto, que a literatura ainda não é unânime quanto ao aspecto epidemiológico, contudo, se reafirma a forma de abordagem cirúrgica excisional como tratamento eficaz definitivo. Faz-se necessária, portanto, a análise clínica, imaginológica e histopatológica para a confirmação diagnóstica da lesão. A observação de tais aspectos é de fundamental importância para um tratamento eficaz e definitivo, reduzindo as chances de recidiva... (AU)


Introduction: The nasopalatine duct cyst is a non-odontogenic lesion with controversial etiology. However, irritating factors, such as local trauma and bacterial infections, can stimulate the epithelial remnant of the nasopalatine duct, leading to a cystic formation. Its predilection occurs in adult men between the fourth and sixth decades. It is usually asymptomatic, being detected by routine examination. Objectives: To present and discuss a case of cyst of the Nasopalatine duct, analyzing the clinical and imaging aspects of the pathology in the face, comparing it with data from the current literature. Case Report: As a result, this article presents the approach of a surgical case of Nasopalatine Ducto cyst in the face, asymptomatic, discovered in a routine imaging exam, biopsied and surgically enucleated, with a 5-year follow-up without recurrence. Final considerations: It is evident, therefore, that the literature is not yet unanimous in terms of the epidemiological aspect, however, the form of excisional surgical approach as a definitive effective treatment is reaffirmed. Therefore, clinical, imaging and histopathological analysis is necessary to confirm the diagnosis of the lesion. The observation of such aspects is of fundamental importance for an effective and definitive treatment, reducing the chances of recurrence... (AU)

ABSTRACT

The osteosarcoma (OSA) is the most diagnosed primary bone cancer in canine patients. This work reports a case of a canine, six years old, mongrel, female, intact, with an OSA in the hard palate. Physical examination detected a firm mass in the palate. Thoracic radiographs, hematological and biochemical exams, histopathological exams and computed tomography were requested. A chondroblastic OSA was diagnosed and the tumor was characterized by immunohistochemistry. There was never evidence of metastasis in this case. The treatment consisted of the combination of conventional chemotherapy, metronomic chemotherapy, and palliative care, aiming at greater survival and well-being of the patient since surgical excision was not possible due to the location and extension of the tumor. Osteogenic sarcomas of the hard palate are rarely seen and described in the literature. In this article we present a characterization of the osteosarcoma with uncommon localization in the hard palate.(AU)


O osteossarcoma (OSA) é a neoplasia óssea primária mais diagnosticada em pacientes caninos. Este trabalho relata o caso de um canino, com seis anos de idade, sem raça definida, fêmea, não castrado, apresentando OSA em região de palato duro. Ao exame clínico, constatou-se uma massa de consistência firme em região palatina. Além do exame clínico, foram solicitadas radiografias torácicas, exames hematológicos e bioquímicos, exames histopatológicos e tomografia computadorizada. Fora então dado o diagnóstico de OSA condroblástico, e o tumor foi caracterizado pela imuno-histoquímica. Não foram observadas evidências de metástases nesse caso. O tratamento instituído consistiu na combinação de quimioterapia convencional, quimioterapia metronômica e cuidados paliativos, almejando maior sobrevida e bem-estar do paciente, uma vez que a excisão cirúrgica não foi possível devido à localização e à extensão do tumor. Neste artigo, apresentou-se uma caracterização do osteossarcoma com localização incomum no palato duro.(AU)

ABSTRACT

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.

ABSTRACT

OBJECTIVES@#The present study aimed to explore the innervation of the anterior hard palatine and its relationship with individual development stage. Specifically, the effects of anesthesia on patients of different ages were observed, and neurodevelopment in the maxillofacial region was invesitgated. References that are helpful in selecting local anesthesia were provided.@*METHODS@#A total of 182 patients with mixed dentition were randomly divided into the nasopalatine nerve block and greater palatine nerve block groups. Then, 219 patients with permanent dentition were divided into an adolescent group (13-18 years old) and adult group (over 19 years old), all of whom underwent bilateral greater palatine nerve block. Palatal mucosal pain sensation was tested pre- and post-anesthesia with Von Frey hairs.@*RESULTS@#Among the children with mixed dentition, bilateral greater palatine nerve block tended to result in better anesthetic effects than nasopalatine nerve block (@*CONCLUSIONS@#The sensation of the anterior hard palatine seems mainly dominated by the greater palatine nerve until mixed dentition and gradually shifted to the nasopalatine nerve in conjunction with maxillary development and tooth replacement. Hence, the innervation of the anterior hard palatine induce a secondary development during the development of the maxilla.

ABSTRACT

Necrotizing sialometaplasia (NS) is a benign, self-limiting inflammatory entity that mainly affects the minor salivary glands located in the hard palate. Classically, NS is characterized as a nodule that evolves to a central ulcer. The most widely recognized triggering factor is an ischemic event. The diagnosis becomes a challenge in non-ulcerated NS cases which is essential to rule out the possibility of salivary gland tumors, especially the malignant ones. Here, we presented a case of a 32-year-old male patient with a 1-month complaint of a painful, slightly elevated erythematous area on the hard palate. Incisional biopsy was performed, and NS was diagnosed based on histopathological and immunohistochemical analyses. Clinicians should be aware of and consider NS as a differential diagnosis of minor salivary gland tumors, particularly when it presents as a non-ulcerated clinical aspect.

ABSTRACT

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)

Objetivo: Describir un caso de exostosis palatina rara y discutir los principales aspectos clínicos involucrados. Presentación del caso: Paciente masculino de 66 años, melanoderma, con antecedentes de aumento de volumen del paladar duro con una evolución de tiempo indefinido, trastornos de masticación y fonación El conjunto de lesiones borró toda la profundidad del paladar y ocupó un gran volumen en la cavidad bucal. La tomografía computarizada de haz cónico mostró áreas corticalizadas en la superficie de la lesión y áreas centrales menos hiperdensas, compatibles con la médula ósea madura. Después de los exámenes y consejos preoperatorios, el paciente se sometió a un tratamiento quirúrgico con anestesia general para eliminar la masa ósea con osteoplastia subyacente a fin de obtener contornos del paladar normales, y el material recolectado fue enviado para realizar biopsia que estableció el diagnóstico de exostosis. El paciente progresó sin complicaciones. Conclusiones: Aunque la exostosis es un crecimiento óseo benigno, causó problemas funcionales al paciente, por lo que requirió tratamiento quirúrgico. Tres meses después de la extracción, los trastornos han vuelto a la normalidad y su rehabilitación protésica está en proceso(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)

ABSTRACT

Pleomorphic Adenoma (PA) is the most common benign salivary gland tumor. The most common sites for minor salivary gland from which PA arises are the palate followed by the lips and buccal mucosa. Calcifications are a common finding in major salivary glands with chronic inflammatory disorders. Major salivary gland tumors rarely show calcifications and it is less common to find them in minor salivary gland tumors. We report a case of pleomorphic adenoma of the hard palate in a 67-year-old female patient with intra-tumoral, irregular and scattered calcifications visible on computed tomography (CT). The treatment was complete surgical excision of the lesion. The diagnosis was confirmed with the histopathological study.


El adenoma pleomórfico (AP) es el tumor benigno de las glándulas salivales más común. Los sitios de mayor frecuencia donde surge el AP en glándulas salivales menores es el paladar seguido de los labios y la mucosa bucal. Las calcificaciones son un hallazgo común en las glándulas salivales mayores con trastornos inflamatorios crónicos, pero en el caso de tumores rara vez muestran calcificaciones y es menos común encontrarlos en tumores de las glándulas salivales menores. Presentamos un caso de adenoma pleomórfico del paladar duro en una paciente de 67 años con calcificaciones intratumorales, irregulares y dispersas visibles en la tomografía computarizada. El tratamiento fue la extirpación quirúrgica completa de la lesión. El diagnóstico se confirmó con el estudio histopatológico

ABSTRACT

Abstract Background: The evaluation of palatal rugae in human identification is important because these structures can remain intact for up to seven days after death. Aim: To compare the area and density of the palatal rugae between ages groups and genders. Settings and Design: A cross-sectional study. Methods and Material: Dental plaster models obtained from patients at the Orthodontic Clinic of University of Uberaba were selected. Two hundred patients were divided into four groups: Group 1:10-15 years; Group 2:16-30 years; Group 3:31-50 years; and Group 4:51-70 years. The palatal rugae and hard palate of each plaster model were outlined and photographed. The evaluation of the area of the hard palate and palatal rugae was performed using the ImageJ software. Statistical analysis used: Kolmogorov-Smirnov, Kruskal-Wallis, Chi-square and Spearman correlation tests using GraphPad Prism 5 statistical software. Results and conclusión: The areas of the palatal rugae and of the hard palate were significantly smaller in the group 4. There was a significant negative correlation between age and palatal rugae area, and between age and hard palatal area. The present study was the first to demonstrate that patients between 51 and 70 years have a smaller palatal rugae area and a smaller hard palate area when compared to other groups. Thus, the evaluation of the hard palate area and of palatal rugae could be used as an adjunct with other methods to determine the age group of an individual; however studies using larger sample size are needed to validate this observation.

ABSTRACT

Maxillectomy is performed to remove the tumor in the palate, maxillary sinus, buccal mucosa or nasal cavity. The resection range depends on the size and the extent of the tumor and it affects speech production or cause nasal regurgitation during feeding. Obturator can occlude an opening such as an oro-nasal fistula and protect the defect area. Successful reconstrucion of the patient's oral cavity who have gone over the maxillectomy is a difficult task. The condition and number of teeth, the remaining support area, and the extent of the defect area have a great influence on manufacturing the obturator. If these factors are disadvantageous, the prognosis of the prosthesis is uncertain. The final obturator must have a sufficient retention in the patient's oral cavity and must not irritate the surrounding tissue and support area where the resection was performed.In this case, a 55 year old female went through the maxillectomy and the only 3 teeth remained. And the retention of the maxillary prosthesis seems to be poor. So that, we fabricated the closed hollow obturator which has reduced weight compared to the conventional obturator. Consequently the closed hollow obturator can give better sealing and the adaptation.

ABSTRACT

Objetivo: Describir un abordaje quirúrgico con injerto en bloque en relación con el conducto nasopalatino y evaluar su desempeño clínico, la percepción sensorial del paciente y el resultado estético en el tratamiento implanto-protésico. Materiales y métodos: Se realizó un estudio clínico en una serie de 10 pacientes con defecto óseo que incluía el conducto nasopalatino con ensanchamiento desfavorable del foramen incisivo. Se colocaron 10 implantes: 6 en incisivo central derecho y 4 en incisivo central izquierdo. La rehabilitación implanto-protésica se llevó a cabo en tres etapas: 1) Diagnóstica: Se evaluaron parámetros clínicoestéticos y se realizó tomografía computarizada de haz cónico; 2) Quirúrgica: Se colocó injerto en bloque por palatino e incisal con regeneración ósea guiada simultánea, y entre seis y diez meses después se colocaron implantes de 3,8 mm de diámetro y una longitud de 10,5 a 15 mm; 3) Protésica: Se atornilló la corona con un torque de 32 N. Se realizó el seguimiento de los pacientes durante 2 a 9 años, en el que se evaluó espesor de la cresta ósea, prueba neurosensorial, percepción del paciente e índices estéticos rosa y blanco. Resultados: Previamente a la cirugía, la media y la desviación estándar del ancho vestibulopalatino de la cresta anterior, a nivel del foramen incisivo, en las alturas 4 mm, 8 mm y 14 mm apicales a la cresta ósea marginal eran de 3,5±2 mm, 5,4±1,5 mm y 6,1±1,9 mm, respectivamente. Las medias totales del espesor postratamiento de la cresta vestibulopalatina en las mismas alturas fueron de 10,09±2,01 mm, 10,5±1 mm y 13,4±3 mm. La evaluación de los resultados de los índices estéticos rosa y blanco fue satisfactoria. Ningún paciente informó alteración neurosensorial. Conclusión: Las variaciones anatómicas del conducto nasopalatino pudieron ser compensadas con un aumento óseo. El injerto en bloque y particulado optimizó la posición tridimensional del implante mejorando el contorno facial del paciente. El control realizado entre 2 y 9 años mostró estabilidad de los tejidos y mantención de la estética lograda.


Aim: To describe a surgical approach with a bloc graft in relation to the nasopalatine duct, to evaluate its clinical performance, the sensory perception, as well as the aesthetic result of the implant prosthetic treatment. Materials and methods: A clinical study was conducted on a series of 10 consecutive patients with bone defects involving the nasopalatine duct with unfavourable widening of the incisive foramen, in which 10 implants were placed, 6 in the right and 4 in the left central incisor. The implant-prosthetic rehabilitation was performed in three stages: 1) Diagnosis: clinical-aesthetic parameters were evaluated and Cone Beam computed tomography scans were analysed; 2) Surgical: a block graft was placed palatal and incisal with simultaneous guided bone regeneration and between 6 and 10 month later implants were placed; 3) Prosthetic: crowns were screwed with a torque of 32 N. Patient follow-up was between 2 to 9 years. Outcomes assessed were: thickness of the bone crest, sensorineural test, pink and white aesthetics scores

ABSTRACT

Objetivo: Este estudo teve por objetivo avaliar o perfil do padrão morfológico de rugosidade palatal de alunos de graduação da Faculdade de Odontologia de Pernambuco FOP-UPE. Metodologia: A pesquisa foi do tipo prospectiva, sendo a amostra constituída de um total de 105 (cento e cinco) indivíduos. Foi realizada a moldagem do arco superior e modelos de gesso foram confeccionados. A partir dos mesmos, a análise morfológica das rugas palatais foi realizada, por um único examinador. Os parâmetros de morfologia das rugas primárias, forma da papila incisiva, direção de alinhamento das rugas, rafe palatina mediana e força das rugas foram analisados. Os dados foram computados numa planilha do Excel, sendo posteriormente, submetidos a análise estatística. Resultados: A idade variou de 18 a 35 anos, a faixa etária mais prevalente foi 21 a 23 anos, maioria de cor branca e IMC (índice de massa corporal) normal (64,8%). A morfologia das rugas primárias mais frequente foi a curva (39,0%). Sobre a forma papila incisiva, aproximadamente metade (49,5%) foi classificada na categoria mínima seguido da cilíndrica (35,2%). Pouco mais da metade (52,4%) teve a classificação de Carrea irregular. Os dois maiores percentuais da rafe palatina foram: não bifurcada (43,8%) e bifurcada posterior (32,4%). Conclusão: pode-se concluir que, foi possível identificar um tipo morfológico específico mais prevalente dentro da população estudada. Diferenças significativas entre as classificações do IMC foram verificadas na dimensão anteroposterior, secundária esquerda e transversal. Foi observada associação significativa entre a classificação do IMC com as inicial e complementar da classificação de Santos


Objective: The purpose of this study was to evaluate the profile of the morphological pattern of palatal roughness of undergraduate students of the College of Dentistry of Pernambuco FOP-UPE, through the various proposed parameters. Methodology: The research was of the prospective type, being the sample constituted of a total of 105 (one hundred and five) individuals. Upper arch molding was performed and plaster models were made. From these, the morphological analysis of the palatal wrinkles was performed by a single examiner. The morphological parameters of the primary wrinkles, incisal papilla shape, direction of alignment of wrinkles, median raphe palatine and wrinkle strength were analyzed. The data were computed in an Excel spreadsheet, and then submitted to statistical analysis. Results: Age ranged from 18 to 35 years, the most prevalent age group was 21 to 23 years, mostly white and normal BMI (body mass index) (64.8%). The most frequent primary wrinkle morphology was the curve (39.0%). About the incisive papilla, approximately half (49.5%) was classified in the minimum category followed by the cylindrical (35.2%). Just over half (52.4%) had the classification of Carrea irregular. The two highest percentages of Rafe palatine were: non-bifurcated (43.8%) and posterior bifurcated (32.4%). Conclusion: It can be concluded that, it was possible to identify a specific morphological type most prevalent in the studied population. Significant differences between BMI classifications were found in the anteroposterior, secondary left and transverse dimensions. Significant association was observed between BMI classification with Santos' initial and supplemental classifications.

ABSTRACT

Malignant-or-paraneoplastic acanthosis nigricans is a verrucous and hyperpigmented tumor affecting the mucosa and skin. In most cases malignant acanthosis nigricans is a distant manifestation of an intra-abdominal primary cancer. While the diagnosis of malignant acanthosis nigricans is challenging, some specific clinical and histopathological findings could lead to an accurate diagnosis. A rare clinical case of a 59-year-old female, who was referred to the maxillofacial surgery service due to a painful oral lesion in the palatine region, is presented. Upon examination, papillomatous lesions were observed on the hard palate, that were later diagnosed as intraoral malignant acanthosis nigricans secondary to gastric cancer. Both local and systemic evaluations are discussed, highlighting the relevance of a multidisciplinary approach consistent with the fact that these manifestations, although infrequent, should generate suspicion among clinicians and therefore motivation to perform a diligent and complete study since it can reveal the presence of a malignant pathology.


La acantosis nigricans maligna o paraneoplásica es un tumor verrugoso e hiperpigmentado que afecta la mucosa y la piel. En la mayoría de los casos, la acantosis nigricans maligna es una manifestación distante de un cáncer primario intraabdominal. Si bien el diagnóstico de acantosis nigricans maligna es desafiante, algunos hallazgos clínicos e histopatológicos específicos podrían conducir a un diagnóstico preciso. Se presenta un caso clínico raro de una mujer de 59 años, que fue derivada al servicio de cirugía maxilofacial debido a una lesión oral dolorosa en la región palatina. En el examen, se observaron lesiones papilomatosas en el paladar duro, que posteriormente se diagnosticaron como acantosis nigricans maligna intraoral secundaria a cáncer gástrico. Se discuten tanto las evaluaciones locales como las sistémicas, destacando la relevancia de un enfoque multidisciplinario consistente con el hecho de que estas manifestaciones, aunque poco frecuentes, deberían generar sospecha entre los clínicos y, por lo tanto, motivación para un estudio diligente y completo, ya que puede revelar la presencia de una patología maligna.

ABSTRACT

During development, bony changes in the palate are reflected in the palatal rugae. Therefore, we hypothesized that the palatal dimensions (PD) influence the shape and number of palatal rugae (PR). The objectives were to record the palatal rugae characteristics (PRC) and palatal dimensions (intercanine distance (ICD), intermolar distance (IMD), palatal height (PH) and palatal area (PA) in Classes I, II and III malocclusion patients and investigate their interrelationship, and statistically examine the possibility of predicting PRC with the PD. Four hundred eighty-one pre-orthodontic study casts of healthy patients with normal palate anatomy were grouped as Classes I, II and III and scanned using 3D cast scanner. The PRC, ICD, IMD, PH, and PA were recorded digitally using 3D enabled software. The data was statistically analyzed. A strong statistically significant difference was observed between PA and number of straight and wavy rugae. ICD and the number of straight rugae were also related. A weak correlation exists between malocclusion classes and PA. The remaining rugae characteristics did not exhibit any relation with palatal dimensions. PA is positively related to the number of straight rugae and negatively related to the number of wavy rugae. Bigger palates have more straight rugae and less number of wavy rugae. A weak correlation between PA and Angle's class I malocclusion exists. We also propose that PA has a developmental association with the number and shape of PR.


Durante el desarrollo, los cambios óseos en el paladar se reflejan en las rugas palatinas. Por lo tanto, planteamos la hipótesis de que las dimensiones palatinas influyen en la forma y el número de las rugas palatinas. Los objetivos fueron registrar las características de las rugas palatinas y las dimensiones palatales (distancia intercanina, distancia intermolar, altura palatina y área palatina) en pacientes con maloclusión de clases I, II y III e investigar su interrelación, y examinar estadísticamente la posibilidad de predecir las características de las rugas palatinas con las dimensiones palatinas. Cuatrocientos ochenta y un estudios pre-ortodónticos de pacientes sanos con anatomía normal del paladar se agruparon como Clases I, II y III y se escanearon con un escáner de emisión 3D. La distancia intercanina, distancia inter molar, altura palatina y área palatina se registraron digitalmente utilizando el software 3D. Los datos se analizaron estadísticamente. Se observó una diferencia estadísticamente significativa entre la altura palatina y el número de rugas rectas y onduladas. Se registró también la distancia intercanina y el número de rugas rectas. Existe una correlación débil entre las clases de maloclusión y la altura palatina. Las características restantes de las rugas palatinas no mostraron ninguna relación con las dimensiones palatinas. El área palatina está relacionada positivamente con el número de rugas rectas y negativamente relacionada con el número de rugas onduladas. Los paladares más grandes tienen más rugas rectas y menor cantidad de rugas onduladas. Existe una correlación débil entre el área palatina y la clase I de maloclusión de Angle. También proponemos que el área palatina tiene una asociación de desarrollo con el número y la forma de rugas palatinas.

ABSTRACT

RESUMEN: El foramen y canal palatino mayor (FPM y CPM) comunican boca con fosa pterigopalatina. El conocimiento adecuado de su morfología, permite el abordaje anestésico del nervio maxilar. En el vivo, el FPM está recubierto por una mucosa gruesa, debido a esto los puntos de referencia óseos y dentarios son importantes para ubicar el sitio de punción. Se ha descrito gran variabilidad en cuanto a la etnia, posición, forma, diámetros, longitudes y permeabilidad. Este estudio tuvo como objetivo describir éstas características en cráneos de adultos chilenos. Se utilizaron 31 cráneos de ambos sexos. En los paladares se determinó; forma, largo, profundidad y ancho. En los FPM se consideró su forma, diámetros y localización. En los CPM se registró su permeabilidad y su coincidencia con la forma del FPM. Los registros se realizaron con cámara digital, compás de precisión, caliper digital, compas tridimensional de Korkhaus y sonda metálica. Los resultados muestran un predominio de la forma cuadrada del paladar por sobre las formas triangular y redondeada. Las mediciones de su largo, ancho y profundidad indican diferencias por sexo y por etnia. La forma del FPM no muestra diferencia por sexo, primando la forma ovalada por sobre la fusiforme y la redondeada. La posición de este mismo foramen tampoco muestra diferencias sexuales, primando la posición frente al tercer molar superior, seguida por la posición frente al espacio entre segundo y tercer molar superior y por último frente al 2do molar superior. Las dimensiones del FPM son mayores en individuos masculinos. Los CPM se observaron en su totalidad permeables y los FPM no siempre coincidieron en forma con la sección transversal del CPM. Estos resultados y su comparación con la literatura indican variaciones importantes, lo que impide establecer directrices objetivas a la técnica anestésica que utiliza esta vía anatómica.


ABSTRACT: The greater palatine foramen and canal (GPF and GPC) communicate with the pterygopalatine fossa. The adequate knowledge of its morphology allows the anesthetic approach of the maxillary nerve. In vivo, the GPF is covered by a thick mucosa, therefore, the bone and dental reference points are important to locate the puncture site. Great variability has been described in terms of ethnicity, position, shape, diameters, lengths and permeability. The objective of this study was to describe these characteristics in skulls of Chilean adults. 31 skulls of both sexes were used. In the palates shape, length, depth and width were determined. In the GPF its shape, diameters and location were considered. In the GPC, their permeability and their coincidence with the shape of the GPF were recorded. The records were made with digital camera, precision compass, digital caliper, Korkhaus three-dimensional compass and metallic probe. The results show a predominance of the square shape of the palate over the triangular and rounded forms. The measurements of its length, width and depth indicate differences by sex and ethnicity. The shape of the GPF shows no difference by sex, with the oval shape prevailing over the fusiform and the rounded. The position of this same foramen also shows no sexual differences, with the position prevailing against the upper third molar, followed by the position in front of the space between the upper second and third molars and finally against the upper 2-molar. The dimensions of GPF are greater in male individuals. The GPC were found to be entirely permeable and the GPF did not always coincide in form with the cross section of the GPC. These results and their comparison with the literature indicate important variations, which prevents establishing objective guidelines for the anesthetic technique used in these cases.
