Abstract: Numerous studies have reported abnormalities in the development of oral structures in congenital infections that also involve microcephaly. In this context, it is necessary to identify possible dental anomalies of shape and/or number in patients with Zika virus syndrome using radiography. The study population consisted of 35 children born with congenital ZIKV who underwent intraoral radiographic examinations for 24 consecutive months. A modified periapical technique was performed in an occlusal position for the maxilla and mandible. Categorical data were expressed as absolute and percentage frequencies and compared using Pearson's Chi-square test, with a 95% confidence interval. Of the entire sample, eight children (22.8%) had dental anomalies of shape and/or number, and four children (11.4%) presented with both anomalies, with agenesis of the upper and lower deciduous/permanent incisors and dental form modifications, such as microdontia and anomalous cusps. When we considered age and sex, there was no statistically significant difference between patients who presented with agenesis and those who presented with modifications. Children with congenital Zika virus syndrome were more likely to have dental modifications in the number and shape of their teeth, and it is essential to implement medium- to long-term monitoring to diagnose other possible alterations throughout the development of the mixed and permanent dentition, favoring their treatment.

Abstract Objective: The aim of this study was to investigate possible malformations in the soft, bone and/or dental tissues in patients with congenital Zika Virus (ZIKV) by clinical and x-ray evaluation. Methodology: Thirty children born with ZIKV and 30 children born without ZIKV (control group) were included in the study. Patients were evaluated over 24 consecutive months according to the variables: sex, age, cleft palates, soft tissue lesions, alveolar ridge hyperplasia, short labial and lingual frenums, inadequate posture of the lingual and perioral muscles at rest, micrognathia, narrow palatine vaults, changes in the teeth shape and/or number, sequence eruption, spasms, seizures and eruption delay were evaluated. Chi-square test, Student's t-test and nominal logistic regression were used (p<0.05). Results: Among the 30 babies examined, the mean age of the first dental eruption was 10.8±3.8 with almost two-thirds of the children (n=18, 60%) experiencing eruptions of their first tooth after 9 months of age, nine children (30%) had inadequate lingual posture at rest, more than half of the children (n=18, 60%) had short labial or lingual frenums. ZIKV babies showed a high prevalence of clef palate (p<0.001), inadequate lingual posture at rest (p=0.004), micrognathia (p=0.002), changes in the shape and/or number of teeth (p=0.006), alteration in sequence of dental eruption (p<0.001) and muscles spasms (p=0.002). The delay eruption was associated with inadequate lingual posture at rest (p=0.047), micrognathia (p=0.002) and changes in the shape and/or number of teeth (p=0.021). The delayed eruption (p=0.006) and narrow palatine vaults (p=0.008) were independently associated with ZIKV. Moreover, female patients showed the most narrow palatine vaults (p=0.010). Conclusions: The children with ZIKV showed a greater tendency to have delayed eruption of the first deciduous tooth, inadequate lingual posture and short labial and lingual frenums.

ABSTRACT Diabetes mellitus (DM) is a disease associated with delayed wound healing of oral ulcers by increased expression of proinflammatory cytokines and cellular apoptosis. Objective to evaluate the influence of Tumor Necrosis Factor alpha (TNF-α) and apoptosis in rats with DM treated with chamomile extract or triamcinolone. Material and Methods Wistar male rats (210.0±4.2 g) were divided into five groups: negative control group (NCG) without diabetes; positive control group (PCG) with DM (alloxan, 45 mg/kg); and groups treated with chamomile extract (normoglycemic= NCG group and diabetic= DCG group) and with triamcinolone (TG). Traumatic ulcers were performed on all animals that received topical triamcinolone, chamomile extract or saline 12/12 hours for ten days. Results On days five and ten the animals were euthanized and the ulcers were analyzed by light microscopy, TUNEL assay, and immunohistochemically (TNF-α). The NCG (p=0.0062), PCG (p=0.0285), NCG (p=0.0041), and DCG (p<0.0001) groups were completely healed on the 10th day, however, there was no healing on the TG (p=0.5127) group. The TNF-α expression showed a significant reduction from the 5th to the 10th day in NCG (p=0.0266) and DCG (p=0.0062). In connective tissue, the TUNEL assay showed a significant reduction in the number of positive cells in NCG (p=0.0273) and CNG (p=0.0469) and in the epithelium only in CDG (p=0.0320). Conclusions Chamomile extract can optimize the healing of traumatic oral ulcers in diabetic rats through the reduction of apoptosis in the epithelium and TNF-α expression.

RESUMO Objetivo: Comparar as condições sistêmicas e orais, além de avaliar as próteses removíveis, associadas aos portadores de Doença Alzheimer e Doença Parkinson, atendidos em dois centros geriátricos situados no município de Fortaleza - Ceará. Métodos: Foram analisados 70 pacientes (entre 57 à 91 anos) com Doença Alzheimer e Doença Parkinson, por meio de avaliação de prontuários neurológicos e exame clinico oral. Tendo sido observadas variáveis de sexo, idade, raça, comorbidades, condições orais e protéticas. Um total de 20 pacientes idosos sem doenças neurológicas consistiu no Grupo Controle. Foi utilizado teste exato de Fischer como análise estatística. Resultados: Em ambos os grupos estudados, a Hipertensão arterial foi a comorbidade mais frequente. Quanto ao exame oral, no grupo com Doença Alzheimer, foi observado que 54.2% apresentou doença periodontal, 34.2% doença cárie. Achados semelhantes foram encontrados em pacientes com Doença Parkinson (31,4%; 22,8% - respectivamente). Entretanto, não foi observada diferença entre os grupos estudados, quanto as manifestações sistêmicas e orais nos dois centros geriátricos (p>0.05). Foi identificado que mais da metade dos pacientes avaliados nesse estudo (57,7%), utilizavam alguma prótese removível, sendo que 86,5% dessas apresentavam-se mal adaptadas, com algum tipo de defeito, principalmente nos idosos Institucionalizados (p= 0.034). Verificou-se, também, diferença estatística na presença de estomatite protética, entre os grupos demência e grupo controle (p= 0.0213). Conclusão: Idosos portadores de Doença Alzheimer e Doença Parkinson tem deficiente saúde bucal, assim como aqueles sem as doenças neurodegenerativas. No entanto, apresentam mais imperfeições e patologias associadas ao uso de próteses removíveis.

ABSTRACT Objective: To compare the general clinical conditions and oral alterations, and also evaluate the prosthesis, in subjects diagnosed with Alzheimer's disease (AD) or Parkinson's disease (PD), attended at two geriatric centers in the city of Fortaleza - Ceará. Methods: 70 patients were analyzed (between 57 to 91 years) with AD and PD, through evaluation of neurological medical records and oral clinical examination. Variables as sex, age, race, comorbidities, oral manifestations and prosthetic conditions were observed. A total of 20 elderly patients without neurological disease consisted the control group (CG). Fisher's exact test and Kruskal-Wallis were used as statistical analysis. Results: In both groups, blood hypertension was the most frequent comorbidity. As for the oral examination in the group with AD, it was observed that 54.2% had periodontal disease, 34.2% caries. Similar results were found in PD patients (31.4%; 22.8% - respectively). However, no difference was observed between the groups, as the systemic and oral manifestations in both geriatric centers (p> 0.05). Was identified more than half of the subjects (57.7%) using dentures, and 86.5% of these had become maladaptive, with some kind of defect. There was statistical difference in the presence of associated oral pathology, denture stomatitis, between dementia and control group (p = 0.0213). Conclusion: Elderly patients with AD and PD have poor oral health, as well as those without neurodegenerative diseases. However, have more defects and disorders associated with the use of removable dentures.
