Highlights COVID-19 has dramatically impacted people’s lives around the world. The effects of the quarantines and social distancing have changed family’s dynamic, including dietary habits. Most parents have avoided seeking dental treatment even after trauma history during the pandemic.

Objective: To evaluate the presence of clinical and radiographic sequelae in primary teeth affected by dental trauma and its association with age at the time of trauma in children attended at a Public Higher Education Institution. Material and Methods: This is a longitudinal clinical study, in which 229 patients with history of dental trauma in primary teeth were examined, totaling 390 traumatized teeth. Relative frequency analysis was used, and for associations, the Chi-square test was used to verify the relationship of age at the time of trauma with variables such as type of trauma. Results: The most prevalent age group was over 24 months, and fall from own height as the main etiological factor; 71.0% of traumas had involvement of 2 teeth, 9.5% had history of anterior trauma and 66.6% of traumas involved supporting tissues. Regarding the type of injury to dental tissue, the most prevalent was enamel fracture (58.3%) and to periodontium, lateral dislocation (30.8%). Children older than two years had less trauma related to dental tissue (p<0.01), higher number of injuries to the periodontium (p=0.03); and most of them did not present extra-oral changes associated with trauma (p=0.01). During the 12month period, 325 teeth were examined, and the most frequent clinical sequelae observed was crown discoloration. In the radiographic evaluation, inflammatory root resorption was the most prevalent. Conclusion: Children older than two years presented more injuries to the periodontium. After 12 months, the main clinical sequelae observed was enamel discoloration and the main radiographic sequelae was inflammatory root resorption.

Background: The bariatric surgery may have negative repercussions on oral conditions. Aim: To evaluate the impact of oral health educational/preventive program developed with patients submitted to gastroplasties. Method: The sample consisted of 109 patients randomly allocated to two groups: intervention group (IG), where they participated in the oral health promotion program that include multiple educational-preventive approaches; control group (CG), where they received usual care from the bariatric clinic staff, without participation in the program. The oral conditions investigated in the pre-operative and postoperative periods of one month (1M) and six months (6M) were: dental caries, periodontal disease, tooth wear, dental plaque and salivary flow. Results: After bariatric surgery, patients in IG presented: fewer changes in enamel (6M: p=0.004), dentin (6M: p=0.005) and gingival bleeding (6M: p<0.0001), reduction in plaque index (1M, 6M: p<0.0001) and increased salivary flow (6M: p=0.039), when compared with CG. Incipient tooth wear was recorded in both groups (6M: p=0.713). Conclusion: There was a positive impact of the implemented program in the prevention of the main oral health problems in patients who underwent gastroplasties, contributing to their quality of life.

Objective: To evaluate the sweetness taste preference levels and their relationship with the nutritional and dental caries patterns among preschool children. Material and Methods: The participants of this cross-sectional study were 191 children aged 4 to 5 years, who were regularly attending public Child Education Centers of a city southern Brazil. Children's preference for sugar was evaluated by the Sweet Preference Inventory; caries prevalence, according to the World Health Organization criteria, and nutritional status, by anthropometric weight and stature measurements, in accordance with child growth standards of the World Health Organization. Results: High levels of sweetness preference were identified. The majority of children (67.5%) opted for the most concentrated sucrose solutions. Excess weight was recorded in 27.7% of the preschoolers. The prevalence of caries was 51.8%, with the mean dmf-t equal to 1.92 (± 2.72) and the decayed (c) component responsible for 94.2% of the index. No significant association between sweetness preference and the nutritional or the oral health patterns could be established. In addition, no association between excess weight and dental caries was identified. The diseases studied were only associated with sociodemographic variables. Excess weight was associated with maternal age (p=0.004) and caries experience with family income (p=0.013). Conclusion: No significant associations could be stablished between the sweetness taste preference and the diseases studied, nor between excess weight and dental caries. However, the findings of high patterns of sweet preference, excess weight and untreated caries experience, highlight the need for the implementation of integrated public policies aimed at controlling both nutritional and of oral health problems in the studied population.

his study compared the caries index (dmft), presence of sucking habits and facial alterations in children attended by the preventive program for infants and children assisted by spontaneous demand, at the same age, at the public sector of Maringá, PR. A total of 100 children were evaluated (1-6 years), who were divided into 2 groups: GI -children attended by the infant program with educational and preventive care and bimonthly follow-up, since the 1 st year of age; GII -children assisted for conventional treatment (preventive and restorative) according to the needs, and follow-up as requested by the parents. Data collection was performed by interview with the parents and clinical examination for evaluation of the dmft and facial alterations. Analysis of data (Mann-Whitney test for dmft comparison and chi-square test for all other comparisons) demonstrated a significant difference (p<0.05) in relation to the dmft index (GI: 0.2; GII: 3.0), percentage of caries-free children (GI: 88%; GII: 57%) and non-nutritive sucking habits (GI: 47%; GII: 75%). The breastfeeding and bottle utilization practices were similar for both groups. Facial alterations were more frequently observed (p<0.05) in GII (48%) than GI (8.4%), especially for the variables (p<0.05) high arched palate (GI: 10.2%; GII: 35.4%), anterior open bite (GI: 14.2%; GII: 35.4%) and mouth breathing (GI: 6.1%; GII: 29.1%). It was concluded that the infant program is more effective than the spontaneous demand program, reaching the goal of oral health maintenance in the child population. Uniterms: Oral health; Infant; Public sector; Dental caries; Malocclusions. objetivo do trabalho foi comparar o índice de cárie (ceo), presença de hábitos de sucção e alterações faciais em crianças atendidas no programa de atendimento preventivo a bebês, com crianças atendidas por demanda espontânea, na mesma idade, no serviço público de Maringá-PR. Foram avaliadas 100 crianças (1-5 anos), divididas em 2 grupos: GI-crianças atendidas no programa de bebês com atendimento educativo-preventivo e retornos bimestrais, desde o 1º ano de vida; GII-crianças atendidas para tratamento convencional (preventivo e curativo) de acordo com a necessidade, sendo o retorno responsabilidade dos familiares. A coleta dos dados foi realizada por meio de entrevista com os pais e através de exame clínico, para avaliação do ceo e alterações faciais. A análise dos dados (Teste de Mann-Whitney para comparações de ceo e teste qui-quadrado para todas outras comparações) mostrou diferença significante (p<0,05) em relação ao índice ceo (GI: 0,2; GII:3,0), componente livre de cárie (GI:88%; GII:57%) e hábitos de sucção não nutritiva (GI:47%; GII:75%). As práticas de amamentação e uso da mamadeira foram semelhantes nos grupos. Constatou-se maior presença de alterações faciais (p<0,05) no GII (48%) do que no GI (8,4%), destacando-se as variáveis (p<0,05) palato ogival (GI: 10,2%; GII:35,4%), mordida aberta anterior (GI:14,2%; GII:35,4%) e respiração bucal (GI: 6,1%; GII: 29,1%). Concluiu-se que o programa de at...

The aim of this study was to investigate the association between oral health status and central obesity (CO) in Brazilian independent-living elderly. A cross-sectional study was carried out in a sample of 489 elderly, who were participants of the Study on Aging and Longevity, in Londrina, state of Parana. The number of natural teeth and use of prostheses were evaluated according to the World Health Organization criteria. The presence of CO was assessed using measures of waist circumference (WC) and waist-hip ratio (WHR). Information concerning sociodemographic profile and some systemic conditions was also collected. Data were analyzed using stepwise logistic regression, α=5%. According to WC and WHR measures, the prevalence of central obesity was 79.3% and 76.1%, respectively. CO according to WC was not associated with oral status. Considering the WHR measure, the following oral conditions were associated to CO: having fewer natural teeth (OR = 2.61; 95%CI = 1.17-5.80), being edentulous and wearing both upper and lower complete dentures (OR = 2.34; 95%CI = 1.11-4.93), and being edentulous wearing only the upper complete denture (OR = 2.64; 95%CI = 1.01-6.95). Traditional risk factors for CO such as gender, dyslipidemia, hypertension and diabetes were associated with both measures. A poor oral health due to extensive tooth loss, whether partial or complete, even if rehabilitated by removable prostheses, may be considered a good predictor of CO in Brazilian independent-living elderly.

Objective: To assess in situ the effect of fluoride associated with nano-hydroxyapatite for the prevention of demineralization of the enamel adjacent to orthodontic brackets. Material and Methods: Eight volunteers wore palatal devices prepared with 6 bovine enamel blocks (5x5x2 mm) with bonded brackets. The volunteers used the devices in two different moments of 14 days each. During the first 14 days, a product containing fluoride + nano-hydroxyapatite was applied twice (experimental group, GNH, n = 48), and for the other 14 days no prevention product was applied (control group, CG, n = 48). In both groups, along the experiment, the blocks were dripped with 20% sucrose eight times daily. After the experiment, all the specimens were sectioned and examined for lesion depth analysis (µm) under polarized light microscopy, and for enamel longitudinal microhardness (measured under the bracket, at 30 µm and at 130 µm from the margin), at seven different depths (10, 20, 30, 50, 70, 90, and 110 µm). Results: Under polarized light, group GNH presented significantly less demineralization depth ( X ¯= 15.01 µm, SD = 33.65) in relation to CG ( X ¯= 76.43 µm, SD = 83.75). Enamel longitudinal microhardness demonstrated significantly higher microhardness for group GNH when compared to CG. Conclusion: Fluoride + nano-hydroxyapatite can be an alternative preventive procedure for demineralization of the enamel adjacent to orthodontic brackets.

O estudo avaliou o conhecimento de profissionais da área de saúde, sobre o diagnóstico e conduta clínica para o tratamento da anquiloglossia em bebês. A amostra (n=84) foi dividida em: G1 (46 médicos da ESF); G2 (13 pediatras); G3 (5 fonoaudiólogas) e G4 (20 dentistas da ESF), que responderam ao questionário (dados pessoais e aplicação do protocolo de avaliação do freio lingual, preconizado por Martinelli et al. (2012)6. Um total de 21 profissionais responderam adequadamente o questionário sendo estes 66,6% do gênero feminino, com idade média de 46,4±12,5 anos de modo que 80,9% já receberam pacientes com queixa de anquiloglossia. Quanto à obrigatoriedade do teste da linguinha constatou-se que o Grupo 1 apresentou menor grau de informação (57,1%) comparado ao Grupo 4 (21,4%), no entanto 57,1% dos profissionais avaliados não o fazem rotineiramente. Referente ao protocolo, nos itens 1, 2 e 3, três profissionais (14,2%) assinalaram figuras com diagnóstico correto (G1 e G3); em relação ao item 4, dez profissionais (47,6%) pontuaram corretamente. Conclui-se que houve grande desconhecimento quanto à obrigatoriedade do teste da linguinha e dificuldade no correto diagnóstico de anquiloglossia em bebês.
