The aim of this cross-sectional study was to evaluate the prevalence of oral mucosal lesions (OMLs) and their association with crack/cocaine addiction in men. Clinical oral examination was performed in 161 adult male patients at the School of Dentistry of the Federal University of Bahia, Brazil. Crack/cocaine addiction was determined from the medical records, and all drug-addicted individuals used both crack and cocaine. All participants (40 crack/cocaine-addicted men and 121 non-addicted men) underwent a systematic evaluation of the lips, labial mucosa, commissures, buccal mucosa and sulcus, gingiva and alveolar ridge, tongue, floor of the mouth, and soft and hard palate by a single examiner. Bivariate and regression analyses were conducted to assess for the presence of OMLs and the association of OMLs with crack/cocaine addiction. OMLs were found in 22 participants with a significantly greater prevalence in the crack/cocaine-addicted group (25 vs. 9.9%; p = 0.01). The most prevalent types of lesions in the addicted group were traumatic ulcer and actinic cheilitis (7.5% for each) followed by fistulae associated with a retained dental root (5%). After adjusting for covariates, crack/cocaine addiction was significantly associated with OMLs (OR = 2.87; 95% CI = 1.08-7.67; p = 0.03). The prevalence of OMLs was higher in crack/cocaine-addicted individuals, and crack/cocaine addiction was significantly associated with OMLs. A public health program aimed at the early diagnosis and treatment of OMLs is vital to improving the oral health status of individuals addicted to crack/cocaine.

Aims: Multisystemic inflammatory syndrome in children (MIS-C) is a condition noted in some children asymptomatic but positive to Sars-cov-2 antibody and it presents clinical and laboratory changes similar to Kawasaki disease (KD). Oral changes have also been observed. This systematic review evaluated oral manifestations detected in children with MIS-C and KD associated to COVID-19. Methods and Results: This work was registered at PROSPERO (#CRD42020225909), following PRISMA guidelines. A comprehensive research was conducted in MEDLINE, Web of Science, EMBASE, LILACS, Scopus, and Grey Literature through August 2021, based on original research evaluating children diagnosed with MIS-C or KD related to COVID-19. Two authors independently screened all retrieved references. Twenty five selected studies evaluated 624 children, mean age 8.78 years. The assessment of the risk of bias (ROB) showed that most of them presented low ROB. Oral manifestations were erythematous mucous membrane, oral ulcers lesions, dry, swollen and cracked lips, and strawberry tongue. Conclusion: MIS-C and KD share the same oral manifestations and their identification may lead to an early diagnosis.

Objective: The aim of this study was to evaluate accuracy of linear measurements assessed from axial tomograms and the influence of the use of different protocols in two cone beam CT (CBCT) units. Methods: A cylinder object consisting of NylonH (Day Brazil, Sao Paulo, Brazil) with radiopaque markers was radiographically examined applying different protocols from NewTom 3G TM (Quantitative Radiology s.r.l, Verona, Veneto, Italy) and i-CAT TM (Imaging Sciences International, Hatfield, PA) units. Horizontal (A-B) and vertical (C-D) distances were assessed from axial tomograms and measured using a digital calliper that provided the gold standard for actual values. Conclusion:The use of different protocols from CBCT machines influences linear measurements assessed from axial images. Linear distances were underestimated in both equipments. Our findings suggest that the best protocol for the i-CAT TM is 13 cm 20 s 0.3 mm and for the NewTom 3G TM , the use of 6 inch or 9 inch is recommended.

Objective To evaluated the relationship between serum vitamin D levels and periodontal healing outcomes in patients with mild or moderate periodontitis. Methods Serum vitamin D levels and periodontal pockets and gingival bleeding were evaluated in 51 patients before and 6 months after non‐surgical periodontal treatment. A t‐test and chi‐square test were used to analyse the data (p ≤ 0.05). Results The mean reduction of periodontal pocket depth was statistically significant higher in patients with vitamin D ≥30 ng/ml than those with <30 ng/ml (CI = −0.23–0.42, p = 0.05), but not clinically significant. Vitamin D level was not associated with the percentage of sites of gingival bleeding on probing at the final evaluation (OR = 0.58, 95% CI = 0.17–1.99, p = 0.39). Conclusion Lower serum vitamin D level was associated with a slightly reduced periodontal healing after non‐surgical periodontal therapy, which should be further investigated in a larger population.

Resumo O objetivo deste artigo foi avaliar a prevalência e os fatores associados à indicação de exodontia em uma população adulta de índios Kiriri do Nordeste do Brasil. 225 indígenas (≥19 anos) foram avaliados. Os critérios de indicação de exodontia adotados foram: dentes com perda de inserção clínica ≥50%, em pelo menos 3 sítios, e, também, raízes residuais. Modelos estatísticos foram utilizados para avaliar associações entre necessidade de exodontia e as variáveis selecionadas. A porcentagem de dentes com indicação de exodontia foi de 4,98%, caracterizando uma média de 1,24 dente por indivíduo. A análise de regressão mostrou associação positiva entre indicação de exodontia e idade ≥35 anos (OR=2,24, 95%IC: 1,13-4,43, p=0,02), renda <R$ 570,00 (OR=3,34, 95%IC: 1,19-9,37, p=0,02) e índice de placa ≥40% (OR=2,38, 95%IC: 1,24-4,56, p=0,01). Uma prevalência de 33% de indivíduos com indicação de um ou mais dentes para exodontia está, principalmente, relacionada aos fatores de risco: idade maior que 35 anos, índice de placa ≥40% e renda inferior a um salário mínimo. Esse estudo reflete tanto a importância da priorização da prevenção em saúde bucal, como a necessidade de ampliação do acesso aos serviços de maior complexidade.

A elevação da expectativa de vida de uma população resulta da interaçãode diversos fatores, como a descoberta dos antibióticos; dos imunobiológicosou vacinas, efetivação de políticas públicas para redução dapobreza e desigualdades como: ações de saneamento básico; habitaçãodigna e maior tempo de permanência na escola. Contudo, o processode envelhecimento acarreta maior incidência e prevalência de doençascrônicas não transmissíveis (DCNT), a exemplo das neurodegenerativas,especificamente a doença de Alzheimer (DA). A doença apresenta evoluçãogradual, com deterioração da memória, aprendizado, orientação,estabilidade emocional, capacidade de comunicação, pensamentos abstratos(paranoias e alucinações) tendo como consequência a incapacidadee exclusão social. Inicia-se com redução motora e cognitiva chegandoà perda da autonomia pessoal, inviabilizando a realização das atividadesda vida diária (AVDs) como nutrição e cuidados básicos de higiene oral.É condição essencial que os cirurgiões-dentistas conheçam característicasclinicas da DA para que os cuidados odontológicos sejam planejadosprevendo as etapas evolutivas da doença e a percepção dos pacientes eseus cuidadores. The increase in the life expectancy of a population results from the interactionof several factors, such as the discovery of antibiotics; immunobiológicosor vaccines, effective public policies to reduce poverty andinequalities such as: basic sanitation actions; housing and longer time inschool. However, the aging process leads to a higher incidence and prevalenceof chronic non-communicable diseases (NCDs), such as neurodegenerative diseases, specifically Alzheimer’s disease (AD). The diseasepresents gradual evolution, with deterioration of memory, learning, orientation,emotional stability, communication capacity, abstract thoughts(paranoias and hallucinations), resulting in incapacity and social exclusion.It begins with a motor and cognitive reduction, leading to the lossof personal autonomy, making it impossible to carry out activities of dailyliving (ADLs) such as nutrition and basic oral hygiene care. It is essentialthat dental surgeons know the clinical characteristics of AD so that dentalcare is planned by predicting the evolutionary stages of the disease andthe perception of patients and their caregivers.
