RESUMO

The scope of this study was to assess the association between preoperative pain, anxiety and the impact of the oral condition on the quality of life of patients treated at the Dental Emergency Service at the Federal University of the Jequitinhonha and Mucuri Valleys. A retrospective cross-sectional study was conducted evaluating data from 240 patient charts aged from 18 to 65 years. Pain was measured by the Heft-Parker Visual Analog Scale; dental anxiety by Corah's Dental Anxiety Scale; and oral health-related quality of life by the Oral Health Impact Profile (OHIP-14). Associations were analyzed using Pearson's Chi-square test (p < 0.05). A statistically significant association was observed between pain and poorer quality of life, with impacts on psychological discomfort (p < 0.001), physical incapacity (p < 0.001) and the psychological (p < 0.001) and social (p < 0.001) domains. Anxiety influenced poorer quality of life, with impacts on the psychological discomfort (p = 0.009), physical disability (p = 0.016), psychological disability (p = 0.011) and social disadvantage (p = 0.028) domains. This study is relevant for the planning of programs and actions aimed at the oral health of patients treated in dental emergency services, prioritizing those with the greatest psychosocial impact arising from oral problems.

RESUMO

Resumo O objetivo deste estudo foi avaliar associação entre dor pré-operatória, ansiedade e impacto da condição bucal na qualidade de vida dos pacientes atendidos no serviço de Urgência Odontológica da Universidade Federal dos Vales do Jequitinhonha e Mucuri. Estudo transversal retrospectivo foi conduzido avaliando dados clínicos de 240 prontuários de pacientes com idades entre 18 e 65 anos. A dor foi mensurada pela Heft-Parker Visual Analogue Scale; ansiedade, pela Corah's Detal Anxiety Scale e qualidade de vida, pelo Oral Health Impact Profile (OHIP-14). Associações foram analisadas pelo Teste qui-quadrado de Pearson (p < 0,05). Foi observada associação estatisticamente significante entre dor e pior qualidade de vida, com impacto nos domínios desconforto psicológico (p < 0,001), incapacidade física (p < 0,001), psicológica (p < 0,001) e social (p < 0,001). Ansiedade influenciou na pior qualidade de vida, com impacto nos domínios desconforto psicológico (p = 0,009), incapacidade fisica (p = 0,016), psicológica (p = 0,011) e desvantagem social (p = 0,028). Esse estudo é relevante para o planejamento de ações voltadas para a saúde bucal dos pacientes atendidos nos serviços de urgência odontológica, priorizando aqueles com maiores impactos psicossociais decorrentes dos problemas bucais.

RESUMO

Cellular neurothekeomas (CNs) are distinctive benign tumors of uncertain histogenesis, with predilection for the skin of the head and neck region. We describe the first case of multiple desmoplastic CNs (DCNs) affecting the oral cavity in a 9-year-old girl. Histopathologic evaluation showed a proliferation of spindle and epithelioid cells, forming nests and bundles, supported by exuberant fibrous stroma, as well as scattered multinucleated floret-like giant cells. The tumor cells were immunopositive for vimentin, CD63, CD56, whereas AE1/AE3, S100, CD34, α-SMA, GFAP, EMA, CD57 and NSE were negative. Ki-67 was <2%. Multiple DCNs should be considered in the differential diagnosis of oral nodular lesions.

RESUMO

OBJECTIVE: The aim was to evaluate the influence of multiple factors on the periapical status of endodontically treated (ET) teeth. METHODS: The patients were clinically and radiographically reevaluated after root canal therapy. The quality of the root-filled canals, coronal restorations, intraradicular posts, dental caries, and periodontal parameters were associated with the teeth's periapical status. RESULTS: The 122 patients provided 154 ET teeth; 97.4% teeth were asymptomatic, and 75.5% had a normal periapical status. The percentage of perfect, satisfactory, and deficient root-filled canals was of the order of 41.6%, 46.1%, and 12.3%, respectively. The percentage of adequate and inadequate coronal restorations was 31.2% and 68.8%, respectively. A total of 14.9% teeth had intraradicular posts, and 29.2% had cavitated carious lesions in the dentin. Gingival bleeding was observed in 31.8% of teeth, and dental biofilm was visible in 58.4%. A total of 11.7% showed pathologic tooth mobility, and 22.1% teeth were diagnosed with periodontal disease. CONCLUSIONS: Carious lesions, gingival bleeding, and tooth mobility were significantly associated with the occurrence of periapical lesions in root-filled canals.

RESUMO

UNLABELLED: The nasopalatine region is composed of structures such as the vomeronasal organ and nasopalatine duct. The nasopalatine duct may provide the communication of the mouth to the nasal cavity in human fetuses and can be obliterated in an adult human. Knowledge on the development of the nasopalatine region and nasopalatine duct in humans is necessary for understanding the morphology and etiopathogenesis of lesions that occur in this region. OBJECTIVE: The aim of the present study was to describe the morphological aspects of the nasopalatine region in human fetuses and correlate these aspects with the development of pathologies in this region. MATERIAL AND METHODS: Five human fetuses with no facial or palatine abnormalities were used for the acquisition of specimens from the nasopalatine region. After demineralization, the specimens were histologically processed. Histological cuts were stained with methylene blue to orient the cutting plane and hematoxylin-eosin for the descriptive histological analysis. RESULTS: The age of the fetuses was 8.00, 8.25, 9.00 and 9.25 weeks, and it was not possible to determine the age in the last one. The incisive canal was observed in all specimens as an opening delimited laterally by the periosteum and connecting oral and nasal cavity. The nasopalatine duct is an epithelial structure with the greatest morphological variation, with either unilateral or bilateral occurrence and total patent, partial patent and islet forms. The vomeronasal organ is a bilateral epithelized structure located alongside the nasal septum above the incisive canal in all the fetuses. CONCLUSIONS: The incisive canal, nasopalatine duct and vomeronasal organ are distinct anatomic structures. The development of nasopalatine duct cysts may occur in all forms of the nasopalatine duct.

RESUMO

BACKGROUND: Fibroblasts on the edges of a surgical wound are induced to synthesize collagen during the healing process which is known as fibroplasia. OBJECTIVE: The aim of this study was to determine the effect of the application of different substances on fibroplasia of cutaneous surgical wounds on rats. MATERIALS AND METHODS: Forty-eight Wistar rats were divided into three groups. A surgical wound 1 cm in diameter and 1 mm in depth was created on the dorsum of each animal. The surgical wounds were submitted to the topical application of an alcoholic extract of 30% propolis, 70% alcohol, or 0.001% dexamethasone in a cream base every 12 hours. The animals were sacrificed three, seven, 14, and 28 days postoperatively. The specimens were histologically processed and stained with Masson's trichome. The assessment of fibroplasia was performed using a scoring system: (1) 5 to 25% collagen deposition; (2) 26 to 50% collagen deposition; (3) 51 to 75% collagen deposition; and (4) more than 75% collagen deposition. RESULTS: There were statistically significant differences in collagen deposition between the substances at all postoperative evaluation times. CONCLUSION: Propolis and alcohol promoted greater collagen deposition in surgical wounds than dexamethasone.

RESUMO

Wound healing is divided into three phases: inflammatory, proliferative and remodeling. Mast cells participate in all these phases. The aim of the present study was to determine the effects of propolis on the population of mast cells in oral surgical wounds in comparison to the results obtained with dexamethasone. This study was prospective, in vivo, randomized, semiexperimental, quantitative and comparative animal. A circular surgical wound was made on the dorsum of the tongue of 90 hamsters divided into three experimental groups: topical application of 30% propolis alcoholic extract (Group 1); 0.1% dexamethasone in orabase cream (Group 2); and orabase cream alone (Group 3). Applications were performed every 12 h throughout the experiment. The postoperative times for killing of the animals were 1, 3, 7, 14 and 28 days. The Student's t test for independent samples was employed in the statistical analysis. In the inflammatory phase of healing, propolis caused a greater reduction in the number of mast cells on the edge and in the central region of the surgical wound in comparison to dexamethasone. Moreover, the number of mast cells on day 1 was lower in the central region of the wounds treated with the orabase cream alone in comparison to dexamethasone. In conclusion, the anti-inflammatory action of propolis mediated by mast cells was more effective than dexamethasone in the inflammatory phase of healing.

RESUMO

PURPOSE: This paper presents a clinical case in which a patient was missing a median central incisor due to trauma but was referred for orthodontic treatment because of suspicions of solitary median maxillary central incisor (SMMCI) syndrome. CASE DESCRIPTION: A 12-year-old female patient visited the clinic with concerns about the appearance of her teeth. An oral examination revealed the presence of a single central incisor that was located on the midline and was adjacent to the maxillary lateral incisors. The patient reported two episodes of dental avulsion (of teeth 11 and 21) that had occurred approximately four years earlier. Tooth 11 was replanted; however, it was subsequently extracted due to pain. A panoramic radiograph and cephalometric analysis revealed a history of unsuccessful root canal treatment on tooth 21, a straight profile and symmetrical facial features. Tooth 21 was extracted, followed by the traction of the maxillary teeth in the mesial direction and the esthetic transformation of the lateral incisors into central incisors and the canines into lateral incisors. CONCLUSION: Dental trauma followed by tooth loss may mimic solitary median maxillary central incisor syndrome.


OBJETIVO: Apresentar um caso clínico de ausência de um incisivo central perdido por traumatismo e encaminhado ao ortodontista com suspeita de apresentar síndrome do incisivo central único (SMMCI). DESCRIÇÃO DO CASO: Paciente gênero feminino, 12 anos com queixa da aparência de seus dentes. Ao exame intrabucal observou-se a presença de um incisivo central único localizado na linha média sem espaçamentos em relação aos incisivos laterais superiores. A paciente relatou dois episódios de avulsão dos dentes 11 e 21, cerca de quatro anos antes. No entanto, devido a sintomas de dor após reimplante, o dente 11 foi extraído. A radiografia panorâmica e análise cefalométrica revelou a presença de tratamento insatisfatório do canal radicular do dente 21, um perfil reto e padrão de equilíbrio facial. Extração do dente 21 foi realizada, com tração posterior dos dentes superiores na direção mesial, seguido pela transformação estética dos incisivos laterais em incisivos centrais e dos caninos em incisivos laterais. CONCLUSÃO: O traumatismo seguido de perda dentária pode mimetizar um quadro de síndrome do incisivo central único.

RESUMO

The aim of the present study was to verify the occurrence of intussusceptive angiogenesis in blood vessels from submandibular lymph nodes responsible for lymphatic drainage of the tongue. A surgical wound inflicted on the ventral tongue of male Wistar rats and submandibular regional lymph nodes were evaluated at different postoperative periods. Scanning electron microscopy (SEM) was used to observe 123 lymph nodes at times 2, 3, 7, 10, 14, and 21 postoperative days. During the analysis of the vascular models with SEM, intussusceptive angiogenesis was observed in all groups evaluated. This was more extensive on the second and third postoperative days (83.33% and 80%, respectively), representing in these groups the expansion of the vascular chain of lymph nodes. At 21 postoperative days, intussusceptive angiogenesis (42.85%) was suggestive of vascular remodeling.

RESUMO

The study of anatomical structures in their normal state allows the identification of pathological changes that can occur in them. Angiogenesis and the vasculature have been widely studied, mainly because of their association with the development of neoplasms. One of the methods applied for such purposes is the corrosion cast technique, which provides a copy of the vessels with normal as well as pathological structures. The replica of the vasculature provided by this technique allows the three-dimensional analysis of vessels by means of scanning electron microscopy. The aim of the present study was to demonstrate, by means of corrosion casts, the angioarchitecture of the submandibular and sublingual glands and lymph nodes. Scanning electron microscopy showed that the three structures have distinct vascular patterns. The corrosion cast technique can be employed in the study of the angioarchitecture of the submandibular and sublingual glands and lymph nodes, but requires specific precautions. The removal of the structures en bloc and the handling of the replicas with the aid of a stereoscopic magnifier reduce the risk of fractures.

RESUMO

The goal of this study was to describe the angioarchitecture of the ventral surface of the tongue from Wistar rats using a vascular corrosion casting technique associated with scanning electron microscopy (SEM). Six Wistar rats were used for the vascular casting method with Mercox resin. Following the resin polymerization, the tongue of each animal was dissected and corroded in a 5% sodium hydroxide solution. Once the corrosion and drying of the specimens were completed, the specimens were mounted on aluminum stubs, coated with carbon and gold and analyzed under SEM. The results showed that the ventral surface of the tongue presents simple, even and abundant vasculature constituted by a vascular plexus consisting of a superficial vascular network and by the ranine veins. The superficial vascular network, made up of the ascending and descending branches, presents as a loose network, with little morphological variation between the capillary loops.

RESUMO

Human myiasis is a parasitosis found in tropical and underdeveloped countries. It usually affects the elderly, unhealthy and mentally disabled individuals. It is caused by dipterous that lay their eggs in necrotic or infected tissues, although areas of the body that are apparently healthy can also be affected. Frequently the fly deposits several eggs on the peripheral parts of scratches and wounds. The treatment of myiasis involves mechanical removal of the larvae with hemostatic pincers. Larvae rupture must be avoided. Application of topical ether or similar volatile substance is useful. Preventive approach measures, including basic health care, hygiene, access to primary health service, and safe water and drainage, are fundamental to prevent human myiasis. The authors present a case report of myiasis infestation over an extensive head and neck squamous cell carcinoma from a 72-year-old patient living in a rural area. Approximately 200 larvae were removed and the patient was taken to the hospital's head and neck surgery service.

RESUMO

A técnica de modelo de corrosão vascular produz a réplica dos leitos vasculares de tecidos normais ou patológicos. Uma vez associada à microscopia eletrônica de varredura (MEV), essa técnica fornece detalhes do arranjo anatômico tridimensional da vascularização, tais como o diamêtro vascular, a impressão das células endoteliais e dos seus núcleos na superficie do modelo vascular e o trajeto das arteríolas e vênulas que compoõem a estrutura avaliada. A imagem tridimensional da réplica vascular proporcionada pelo MEV é uma das vantagens do método. O presente estudo teve por objetivo descrever a técnica de modelo de corrosão vascular, discutir suas vantagens e desvantagens, bem como exemplificar o seu emprego na pesquisa odontológica.

RESUMO

No presente estudo, são descritas as características clínicas e epidemiológicas de 61 casos de paracoccidioidomicose, atendidos no Serviço de Estomatologia do Hospital São Lucas da PUCRS, no período de junho de 1976 a junho de 2004. O Rio Grande do Sul é considerado uma região endêmica da doença devido às condições eco-epidemiológicas para o desenvolvimento do fungo. Observou-se que a doença ocorreu em 58 (95 por cento) homens e 3 (5 por cento) mulheres, predominando a faixa etária de 40 a 59 anos (70,5 por cento), e a profissão vinculada à agricultura em 27 (44,3 por cento) pacientes. O hábito de fumar foi prevalente em 52 (85,3 por cento) pacientes da amostra e muitos eram, também, etilistas. Todos os casos apresentavam manifestações estomatológicas, sendo que as lesões orais ocorreram predominantemente com aspecto ulcerado e moriforme, observadas em vários sítios anatômicos. As evidências radiográficas de lesões pulmonares estavam presentes em 32 (65,3 por cento) radiografias avaliadas.

RESUMO

The aim of the article was to describe clinical and epidemiological features of 61 oral paracoccidioidomycosis cases from the Stomatology Department of São Lucas Hospital, analyzed from July 1976 to June 2004. The State of Rio Grande do Sul is an endemic region due to ecoepidemiologic conditions, that are favorable for the development of the yeast. Men are the most affected gender, with 58 (95%) affected compared to 3 (5%) women. Ii is most prevalent (70.5%) between 40 and 59 years of age. Agricultural labor was the most common occupation with 27/61 (44.3%) patients. Tobacco smoking was prevalent in 52 (85.3%) of the sample, and alcoholism was a frequent finding. All the patients showed stomatologic manifestations, with ulcers and mulberry-like stomatitis the most prevalent, these oral lesions were also observed in many anatomical sites. Alterations were present in 32 (65.3%) of the pulmonary radiographs.
