Self-Medication for Toothache in Children: A Cross-Sectional Study

ABSTRACT Objective: To construct, validate, and apply a questionnaire to assess and characterize the practice of self-medication performed by parents or children's guardians undergoing dental care. Material and Methods: A questionnaire was constructed, validated, and applied through personal interviews in the teaching clinics of two higher education institutions in the Federal District. Absolute and relative frequencies of categorical variables were calculated using descriptive statistics. Quantitative data were presented as mean and standard deviation. The chi-square test measured the association between the studied variables and self-medication. Results: One hundred and five participants were interviewed between August 2019 and November 2020. The average age of the participants was 37 (± 9) years, and most were mothers of the children who attended (78%) and users of the public health system (94.2%). The average family income was 1.88 minimum wage, and the most prevalent educational level was complete high school (40%). Conclusion: Despite the high level of knowledge about medication safety in children, self-medication was practiced in 50% of them. Difficulty in accessing dental treatment was mentioned by most as a justification. Self-medication was associated with dental pain, continuous medication use, and family self-medication habits.

Xerostomia and dysgeusia in the elderly: prevalence of and association with polypharmacy

Xerostomia is defined as the perception of dry mouth, and dysgeusia, as a change in taste. Both are common complaints in the elderly, especially among those making use of polypharmacy drug combinations. Aim: This study aimed to determine the prevalence of xerostomia and dysgeusia and to investigate their association with polypharmacy in the elderly. Methods: older people under follow-up at the Multidisciplinary Elderly Center of the University Hospital of Brasília were interviewed and asked about health problems, medications used, presence of xerostomia and dysgeusia. Descriptive statistics were used to determine the prevalence of the symptoms surveyed. The chi-square test was used to investigate the relationship between xerostomia and dysgeusia and polypharmacy. Secondary associations were performed using binomial logistic regression. Results: Ninety-six older people were evaluated and of these, 62.5% had xerostomia and 21.1%, had dysgeusia. The average number of medications used was 4±3 medications per individual. Polypharmacy was associated with xerostomia but not dysgeusia. It was possible to associate xerostomia with the use of antihypertensive drugs. Conclusion: Xerostomia was a frequent complaint among elderly people making use of polypharmacy, especially those using antihypertensives. Antihypertensives and antidepressants were used most drugs by the elderly and exhibited interactions with drugs most prescribed in Dentistry. Two contraindications were found between fluconazole and mirtazapine; and between erythromycin and simvastatin

Manejo de cárie radicular: um guia para o dentista brasileiro baseado na tradução e adaptação cultural do consenso internacional/ORCA E EFCD / Management of root caries: a guide for the Brazilian dentist based on the translation and cultural adaptation of the international consensus/ORCA and EFCD

Objetivo: A cárie radicular é um problema da Odontologia moderna, porém é notável a falta de diretrizes sobre o seu manejo. Objetivamos elaborar e adaptar um guia a partir da tradução das recomendações do consenso in-ternacional European Organization for Caries Research (ORCA) e European Federation of Conservative Dentistry (EFCD) para as tomadas de decisão clínica na intervenção do processo de cárie na pessoa idosa, com foco na cárie radicular. Materiais e métodos: O protocolo de tradução das recomendações do consenso internacional consistiu nas etapas: (1) tradução inicial, (2) síntese da tradução, (3) retradução, (4) revisão por comitê de especialistas, com adaptação cultural. A partir da tradução, foi desenvolvido um guia com diretrizes para tratamento de cárie radicular no Brasil. Resultados: Para prevenção de novas lesões é recomendada a escovação diária com dentifrício >1.500ppm/F. Dentifrícios com 5.000ppm/F ou vernizes (>20.000ppm/F) podem ser indicados para paralisar lesões radiculares ativas e para prevenção em pessoas idosas com alta suscetibilidade à cárie radicular, e o Diamino Fluoreto de Prata (>30%) para paralisar lesões ativas. Intervenções invasi-vas diretas são indicadas dependendo da situação clínica. Discussão: Nota-se uma falta de interesse em estudos primários sobre tratamentos para cárie radicular, criando assim uma lacuna em relação ao seu manejo, que reflete no nível de evidência detectado pelo consenso. Conclusão: Guias clíni-cos são importantes para reduzir a lacuna entre a pesquisa e a prática clínica. Essa tradução para o português facilitará o acesso dos dentistas bra-sileiros em relação a evidência consolidada até o momento para o manejo de cárie radicular.

Aim: Root caries are a problem in modern dentistry, but the lack of guidelines regarding their management is notable. We aim to develop and adapt a guide based on the translation of the recommendations of the international consensus as outlined by the European Organization for Caries Research (ORCA) and the European Federation of Conservative Dentistry (EFCD) for clinical decision-making in the intervention of the caries process in the elderly, with a focus on root caries. Materials and methods: The protocol for translating the recommendations of the international consensus consisted of the following steps: (1) initial translation, (2) synthesis of the translation, (3) back-translation, (4) review by an expert committee with cultural adaptation. Based on the translation, a guide was developed with guidelines for the treatment of root caries in Brazil. Results: To prevent new lesions, daily brushing with toothpaste >1,500ppm/F is recommended. Toothpaste with 5,000ppm/F or varnishes (>20,000ppm/F) may be recommended to paralyze active root lesions and for prevention in elderly people with high susceptibility to root caries, and Silver Diamine Fluoride (>30%) to paralyze active lesions. Direct invasive interventions are indicated depending on the clinical situation. Discussion: There is a lack of interest in primary studies on treatments for root caries, thus creating a gap in relation to its management, which is reflected by the level of evidence detected in the consensus. Conclusion: Clinical guidelines are important to reduce the gap between research and clinical practice. This translation into Portuguese will facilitate access by Brazilian dentists to the consolidated evidence gathered to date for the management of root caries.

SARS-CoV-2 infection among Brazilian dentists: a seroprevalence study

Abstract: This cross-sectional study aimed to determine the seroprevalence of SARS-CoV-2 infection among Brazilian dentists and its associated factors. Stratified random sampling of dentists from 33 administrative regions of the Federal District (Brazil) was performed. The presence of antibodies was verified by the OnSite COVID-19 IgG/IgM Rapid Test. Participants answered a survey about sociodemographic characteristics, exposure to COVID-19, and professional practice. A chi-square test was performed between serostatus and exposure variables. Mann-Whitney tests were carried out for quantitative variables. Odds ratio (OR) and 95% confidence intervals (95%CI) were calculated. A series of binomial logistic regression models was performed. The seroprevalence of SARS-CoV-2 infection among 324 selected dentists was 19.1%. There was a statistically significant association between seropositivity and previous confirmed diagnosis of COVID-19, loss of taste or smell, diagnosis of COVID-19 in a household member, and treatment of a patient with fever. Dentists with a previous confirmed diagnosis of COVID-19 had 29.5 [12.7-68.4] higher odds to exhibit positive serology test results. Dentists with confirmed diagnosis of COVID-19 in a household member had 2.5 [1.1-5.3] times higher odds to exhibit positive serology test results. Professionals with loss of taste or smell in the last 15 days had 5.24 [1.1-24.1] times higher odds to exhibit positive serology test results, and, for those who had treated patients with fever, there were 2.99 [1.03-8.7] times higher odds to exhibit negative serology test results. There was a similar prevalence rate of infection among dentists and in the general population. Nevertheless, this finding applies to the epidemiological situation in 2020, before the development of vaccines and the emergence of SARS-CoV-2 Delta variant.

Frenotomia lingual em lactentes

O objetivo deste trabalho foi realizar uma revisão de literatura acerca do freio lingual anômalo em lactentes, relacionando diagnóstico e tratamento. Revisão de literatura: esta anomalia limita os movimentos da língua durante o choro, lalação e pode gerar desconforto durante a amamentação. A metodologia do trabalho constituiu em buscas de artigos publicados em língua portuguesa e inglesa nas bases de dados Bireme, Google Acadêmico e PubMed, entre os anos de 2004 e 2016. Foram identificados 645 artigos através da combinação de palavras-chave, sendo que 29 foram utilizados por apresentarem resultados condizentes com o objetivo desta revisão. Considerações Finais: através dos estudos consultados não foi possível identificar um instrumento padrão-ouro que diagnostique a anquiloglossia em bebês, a despeito do fácil diagnóstico. Há controvérsias na literatura em relação ao tratamento por meio da frenotomia e sua contribuição para a melhora na amamentação, movimentos da língua e desconforto da mãe ao amamentar, embora grande parte dos estudos demonstre benefícios evidentes.

In situ carcinoma developed over oral lichen planus: a case report with analysis of BUB3, p16, p53, Ki67 and SOX4 expression

AbstractOral lichen planus (OLP) represents a common mucocutaneous disease. Various authors have suggested that OLP has malignant potential; however, the mechanisms involved in malignant transformation have not yet been elucidated. A 79-year-old man presented a white lesion for five months in the buccal mucosa diagnosed as OLP. After two months using 0.05% clobetasol ointment for treatment, the lesion became ulcerated. A new biopsy of the same lesion was performed, and histological analysis showed an in situ oral carcinoma (ISOC). An immunohistochemistry panel was performed, and p16 expression was negative in OLP, however, it showed weak cytoplasmic staining in ISOC. There was strong nuclear BUB3 staining in both OLP and ISOC areas. p53 showed less intense nuclear staining in both regions. Ki67 was negative in OLP area, but showed nuclear staining in the ISOC. SOX4 was negative in both studied areas. BUB3 expression, first reported in this case, and the p16 expression may suggest some influence of these genes on pathogenesis or malignant potential of OLP.

Assessment of quality of prescription by dental students

Objective: The main objective of this study was to evaluate changes in prescribing pattern of Dentistry students throughout academic course. Methods: A case of non-complicated dental extraction was presented to all students that had completed their pharmacology coursework (from 4th semester to the last semester). The students were grouped according to year of study and were asked to prescribe paracetamol for pain control. A maximal score of 5 points was calculated from three subscores for identification of professional and patient (1.0 point), drug concentration, dosage, and quantity (1.5 points); and drug information, instructions, and warnings (2.5 points). The data were expressed as medians [95% confidence intervals (CIs)] and were compared using the Kruskal-Wallis test followed by Dunn's post hoc test. A p<0.05 value was considered statistically significant. A total of 92 students participated the study (2nd year, N=12; 3rd year, N=32; 4th year, N=28; 5th year, N=20). Results: The quality of prescription showed improvement between 2nd-year students [2.0 (1.5-2.5)] and 4th-year students [3.2 (2.9-3.5), p<0.05]; 4th- and 5th-year students [3.6 (3.5-3.8)] performed similarly. Lack of information about pharmacological treatment, side effects, and administration route were the major deficiencies observed. Conclusion: Although Dentistry students present a general improvement in their prescribing performance, deficiencies remain even in advanced students. The data suggest that the teaching of good prescription practices should extend throughout the later phases of preprofessional dental education. .

Doença de Alzheimer: características e orientações em Odontologia / Alzheimer's disease: characteristics and guidelines in dentistry

A demência é classificada como uma desordem mental de caráter neurodegenerativo que atinge o Sistema Nervoso Central. A doença de Alzheimer é a forma de demência mais prevalente que acomete pessoas idosas e é definida como a perda progressiva e persistente demúltiplas áreas das funções intelectuais. Promove gradual deteriorização da memória, aprendizado, orientação, estabilidade emocional e capacidade de comunicação. Além disso, pensamentos abstratos (paranóias e alucinações) e o declínio dos cuidados pessoais, como tomar banho e a realização da higiene bucal são comuns, interferindo na vida social e diária do indivíduo. De acordo com a evolução, a doença de Alzheimer é dividida em três fases distintas: inicial, intermediária e final. Este estudo objetiva abordar as características e sugerir orientações ao atendimento odontológico nas fases representativas da evolução desse quadro demencial. O cirurgião-dentista deve ter conhecimento dos diferentes estágios desta doença e suas características para direcionar a atenção em saúde bucal de forma individualizada a seus pacientes. A participação dos cuidadores, familiares, além da equipe de saúde é fundamental e também necessária para a manutenção da saúde bucal desses idosos.

Dementia is classified as a mental disorder of a neurodegenerative nature that affects the Central Nervous System. Alzheimer's disease is the most prevalent form of dementia that affects elderly people and it is defined as a progressive and persistent loss of multiple areas of intellectual functions. It gradually promotes deterioration in memory, learning, orientation, emotional stability and ability to communicate. Moreover, abstract thinking (paranoia and hallucinations) and the decline of personal care such as bathing and performing oral hygiene are common, interfering in the individual's social and daily life. According to its development, Alzheimer's disease is divided into three distinct stages: initial, intermediate and terminal stage. The aim of this study was to approach the characteristics and suggest guidelines for dental attendance in the representative stages in the development of this dementia condition. The dentist should be aware of the different stages of this disease and its characteristics to provide patients with individual oral health attention. The participation of caregivers, family, and the health team is fundamental and it is also necessary to maintain oral health of these elderly patients.

Effects of intrathecal L-and N-type calcium channel blockers on the antinociception evoked by opioid agonists in the rat tail flick test

The effects of intrathecal administration of nimodipine or omega-conotoxin GVIA(L- and N-type calcium channel blockers, respectively) alone or followed by DAMGO, DADLE or bremazocine (mu-, delta- and kappa- opioid agonists, respectively) were studied on the rat tail flick test. The N- (16 to 64 pmoles), but not the L-type blocker (60 to 240 pmoles) produced a dose and time-dependent increase in the latency for the tail-flick reflex. DAMGO (30 to 120 pmoles) or bremazocine (190 to 560 pmoles), but not DADLE (50 to 200 pmoles), produced a dose-dependent increase in the latency for the tail-flick reflex. The effect of the highest dose of DAMGO was smaller, while the effects of DADLE and bremazocine were not changed after nimodipine (60 pmoles). The effects of DADLE were significantly potentiated, while the effects of DAMGO and bremazocine were not changed after omega-conotoxin GVIA (16 pmoles). The intrathecal administration of an N-type calcium channel blocker with a delta-opioid agonist seems to be the most effective combination to produce antinociception in the rat tail flick test.

Interpretação radiográfica do côndilo / Condyle radiographical interpretation

Muitas pesquisas são realizadas procurando avaliar a projeção radiográfica da ATM. O presente estudo empregou a técnica transcraniana de Updegrave e através de meios contrastes colocados no côndilo de um crânio seco, foram realizadas as tomadas radiográficas. Após o exame das radiografias verificou-se que as regiões do côndilo marcados com o meio de contraste tiveram projeções bem diferentes às correspondentes regiões anatômicas
