Could Teledentistry Be a Solution in the Diagnosis of Oral Lesions?

In recent years, teledentistry has gained visibility, especially because of the COVID-19 pandemic. Concerning oral medicine, there is great expectation, particularly about its potential to promote early diagnosis of oral lesions. In southern Brazil, two initiatives have shown a positive influence on each other and have led to greater awareness of oral cancer and more access to qualified advice on diagnosing and managing oral lesions. Although the contributions of this approach are promising, there are barriers to be overcome.

Sun protection as a protective factor for actinic cheilitis: Cross-sectional population-based study.

OBJECTIVE: To determine whether sun protection is associated with lower occurrence of actinic cheilitis in adults living in a city from southern Brazil. MATERIALS AND METHODS: A multi-stage proportional sample of 404 individuals 18 years and older was obtained. Interviews and clinical examinations were conducted in participants' households. Four categories of self-reported use of sun protection were determined. Multivariable Poisson regression was used to assess the associations. RESULTS: Prevalence of actinic cheilitis was 47.1%. In the first main-effects multivariable model, AC was significantly associated with sex, age, skin colour and duration of sun exposure, but not with sun protection. However, the association between sun protection and actinic cheilitis was modified by the time of sun exposure. Among those exposed ≥4 hr/day to sun, individuals using physical protection or physical + chemical protection were 33% (prevalence ratio = 0.67, 95% confidence interval [CI] 0.47-0.94, p = .02) and 36% (PR = 0.64, 95% CI 0.47-0.94, p = .02), respectively, less likely to have actinic cheilitis than those who did not use any sun protection, adjusting for sex, age and skin colour. CONCLUSIONS: Physical and chemical sun protection were associated with lower occurrence of actinic cheilitis in individuals with greater exposure to sun.

Garlic burn trauma of the oral mucosa in a patient with trigeminal neuralgia: A case report.

Garlic is one of the most common medicinal plants used since ancient times to treat diverse diseases within several cultures worldwide. Nevertheless, this plant has the potential to cause chemical burns of the skin and mucosa. This report presents a case of a garlic burn in the palate of a 57-year-old woman who applied garlic to the palate to relieve the pain of trigeminal neuralgia. This case demonstrates the potential of garlic to cause chemical burns to the oral mucosa and raises an alert to oral health professionals regarding inappropriate self-treatment methods.

Pleomorphic sarcoma of maxillary sinus: Clinical report of a patient initially diagnosed with denture-induced fibrous hyperplasia.

Undifferentiated pleomorphic sarcoma is a high-grade soft-tissue malignant tumor that is rare in the head and neck region. A 74-year-old woman displayed a large nodular lesion in the maxillary alveolar mucosa, which was initially identified as denture-related fibrous hyperplasia. Although her prosthodontist has adjusted the maxillary complete denture to relieve pressure on the lesion, it increased in size over time. Computed tomography images of the maxillary sinus showed an extensive destructive lesion. A biopsy was performed, and microscopic examination revealed a poorly differentiated malignancy with numerous spindle cells. Immunohistochemistry reactions were negative for CD45, CD30, CD68, CD34, cytokeratin, S100, desmin, and smooth muscle actin. These findings led to the diagnosis of an undifferentiated pleomorphic sarcoma of the maxillary sinus.

Uncommon oral manifestation of lichen sclerosus: critical analysis of cases reported from 1957 to 2016

Background: Lichen sclerosus is a mucocutaneous autoimmune disease which might be initiated by infectious pathogens as Borrelia Bugrdorferi and HPV. This disease shows destructive potential and is rarely diagnosed in oral mucosa. The purpose of this paper is to evaluate the characteristics of cases described in literature from 1957 to 2016, looking to provide valuable evidence about clinicopathologic features of this disease. Material and Methods: A MedLine search was performed aiming to find oral lichen sclerosus cases in literature and discuss its demographical and pathological characteristics as well as treatment methods performed for these cases. Results: 34 oral lichen sclerosus cases with histological confirmation and one clinicopathologic study linked with this disease were found in literature. Oral lichen sclerosus affected most commonly female patients, were asymptomatic and not associated to skin or genital lesions. Furthermore, affected patients in a range of 7 - 70-years old (Average age = 31.81). Conclusions: Oral lichen sclerosus is a rare pathologic process with slight predilection for prepubertal girls, for which topical corticosterois have demonstrated satisfactory therapeutic value (AU)

Sialolitíase em glândula salivar menor: relato de caso e revisão de literatura / Sialolithiasis in minor salivary gland: case report and literature review

A sialolitíase é uma afecção que se caracteriza pela obstrução da glândula salivar ou de seu ducto devido à formação de estruturas calcificadas acometendo predominantemente as glândulas submandibulares e muito raramente as glândulas salivares menores. O objetivo deste trabalho é realizar um relato de caso sobre sialolitíase em glândula salivar menor. Paciente do sexo masculino, leucoderma, 54 anos, se apresentou com queixa principal de "tumor na boca". O exame físico intrabucal revelou um nódulo localizado na mucosa labial do lado superior direito, próximo a comissura, único, medindo aproximadamente 2 centímetros no seu maior diâmetro. A ultrassonografia da região do lábio superior evidenciou a hipótese diagnóstica de corpo estranho. O diagnóstico diferencial e o clínico incluíram reação a corpo estranho. Foi realizada a biópsia excisional e durante o ato cirúrgico, foi encontrado um material endurecido, de aproximadamente 3 mm, de cor amarelada, que foi enviado para análise histopatológica, a qual revelou fragmento mineralizado compatível com sialolito. Com base nos achados clínicos e imaginológicos o diagnóstico foi de sialolitíase. Após três meses de acompanhamento, o paciente se apresentou sem evidência da doença. Esta revisão de literatura e o presente relato permitiram concluir que um exame clínico criterioso associado a exames imaginológicos adequados são essenciais para a obtenção de um diagnóstico clínico correto(AU)

Sialolithiasis is a condition characterized by obstruction of salivary gland or its duct due to formation of calcified structure, predominantly affecting the submandibular glands or, rarely, the minor salivary glands. The main objective is to report a case of sialolithiasis in the minor salivary gland on a male patient, leucoderma,54, and his main complaint was a "tumor in the mouth". Intraoral physical examination revealed a nodule located on labial mucosa of the upper right side of the mouth, near the commissure, single, and its diameter measuring approximately 2 cm. The ultrasound examination on the upper lip region resulted in a strange body. The differencial and clinical diagnosis was included strange body. During the excision biopsy surgery, a hardened material, measuring about 3 mm and yellowish was removed and sent for histopathologic exams and the diagnosis was sialolithiasis. After three mouths' follow-up, the patient was free of the disease. This literature review and the present case concluded that a careful clinical examination associated with imaging and histopathology examinations are essential for obtaining a correct clinical diagnosis(AU)
