Oral and Dental Examinations Findings in 15 Zoo Bolivian Squirrel Monkeys (Saimiri boliviensis) and Black-Tufted Marmosets (Callithrix penicillata).

As part of an annual wellness evaluation, we performed oral and dental examination under general anesthesia in 7 zoo Bolivian squirrel monkeys aged 10 and 15 years, and 8 zoo black-tufted marmosets aged between 1 and 7 years. No oral discomfort was observed in any animal prior to the procedure. Apart from dilacerated roots of second mandibular incisor teeth in Bolivian squirrel monkeys and one case of presumably odontodysplasia in a black-tufted marmoset, no major variations in number and shape of the present teeth and roots were revealed. All 15 animals had gingivitis, but periodontitis was only diagnosed in 3 black-tufted marmosets. Most commonly diagnosed dental pathology in Bolivian squirrel monkeys was attrition/abrasion, affecting 11.9% of all teeth, followed by caries, which was only diagnosed in older animals. Altogether 8 fractured teeth were diagnosed in Bolivian squirrel monkeys only, with root fracture being the most common type, followed by complicated crown fracture and complicated crown-root fracture. Radiographic signs of endodontic disease were found in 10 teeth in Bolivian squirrel monkeys and in one nonvital tooth with intact crown in a black-tufted marmoset. We associated high occurrence of caries in the older Bolivian squirrel monkeys with their diet and saliva characteristics of these animals. Lack of any periodontitis in Bolivian squirrel monkeys may partially be attributed to limitations of radiography technique, although squirrel monkeys appear to be far less susceptible to naturally occurring periodontitis than marmosets.

Validity of the self-reported number of teeth in Chilean adults.

BACKGROUND: Clinical dental evaluations are considered complex and costly measurements that epidemiological surveillance studies of multiple simultaneous chronic diseases currently require, for example National Health Surveys (ENS). Accordingly, simpler and more affordable methods need to be validated. The aim of this study was to assess the validity of the self-report on the total number of teeth in the general Chilean adult population. METHODS: A substudy was conducted on ENS 2016-2017 participants. A stratified random sample of 101 of them was subjected to a telephone questionnaire. This information was then compared with the results obtained from the oral examination performed by a trained nurse during a home visit. Spearman correlations, intraclass correlation coefficients and the Bland-Altman method were used to analyse the data. RESULTS: In men, the average number of teeth recorded during the oral examination coincided with the number of teeth in the self-report (22 teeth). In women, the total teeth average was 18 and 19 teeth according to the examination and self-report, respectively. For the total number of participants, a strong and significant Spearman correlation was obtained (ρ = 0.93); in men and women, the Spearman correlation observed was also strong and significant (ρ = 0.90 and ρ = 0.96 respectively). The value of the intraclass correlation coefficient indicated a significant concordance (CCI = 0.96) in both men and women (CCI = 0.93 and 0.98 respectively). A tendency to greater correlation was observed as the number of teeth decreased. CONCLUSIONS: The number of teeth self-reported by the subjects in this study correlated with the number of teeth recorded in the clinical examination. Self-report is a valid method to determine the number of teeth in national health surveys.

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)

Prevalence of oral lesions in elderly patients on oral cancer prevention campaigns in Paraná state Brazil 1989-2013 / Prevalência de lesões orais em pacientes idosos atendidos em campanhas de prevenção de câncer bucal no estado do Paraná, Brasil entre 1989 - 2013

Objective: recently, there has been a rapid aging process of the world population. Despite of a longer permanence of natural teeth and a reduction of oral diseases caused by the improvement of life conditions and the provision of health care, the prevalence of oral diseases in the elderly is still considered significant. Therefore, the aim of this study is to evaluate the epidemiological profile of elderly patients (above 60 years old) attended in 25 years of campaigns oral cancer prevention in the Paraná state, Brazil, between 1989 and 2013. Material and Methods: Patients, volunteers, were evaluated during 25 years of oral cancer prevention by the campaign team and all patients were evaluated in a methodical way with inspection of all intra-oral areas. Results: a total of 22,909 patients were attended during the 25 years of projects. Of these, 6,134 were older than 60 years old, with appearance of 1,523 oral lesions during the examination and 4,611 patients had no oral alterations during the dentist evaluation, among those were found injuries by traumatic origin, inflammatory lesions and others types of injury. Conclusion: it is clear the necessity for specialized care and active surveillance of these patients, since it is a consensus in the literature that the best treatment is early diagnosis. It is also necessary the development of epidemiological studies of the elderly population, which are scarce and difficult to elaboration of plans for effective action to meet the specific demands of this age group.

Objetivo: a população mundial atualmente sofre com um rápido processo de envelhecimento. Apesar de uma maior permanência dos dentes naturais e da redução de doenças bucais causadas pela melhoria das condições de vida e da prestação de cuidados de saúde, a prevalência de doenças bucais em idosos ainda é considerado significativa. Portanto, o objetivo deste estudo é avaliar o perfil epidemiológico dos pacientes idosos (acima de 60 anos) que foram atendidos em 25 anos de campanhas de prevenção do câncer de boca no estado do Paraná, Brasil, entre 1989 e 2013. Material e Métodos: Os pacientes foram selecionados voluntariamente e avaliados durante 25 anos de prevenção de câncer bucal pela equipe participante, os quais foram avaliados de forma metódica com a inspeção de todas as áreas intra-orais. Resultados: um total de 22.909 pacientes foram atendidos durante os 25 anos de projetos. Destes, 6.134 tinham mais de 60 anos, com presença de 1.523 pacientes com lesões orais durante o exame e 4.611 pacientes sem alterações orais durante a avaliação do dentista. As lesões encontradas tinham origem traumática, inflamatórias e outras. Conclusão: é evidente a necessidade de atendimento especializado e da busca ativa desses pacientes, uma vez que é um consenso na literatura de que o melhor tratamento de lesões orais é o diagnóstico precoce. Também é necessário o desenvolvimento de estudos epidemiológicos da população idosa, que são escassos e difíceis de elaboração assim como a realização de planos de ação eficazes para atender às demandas específicas desta faixa etária.
