The present study aimed to evaluate the prevalence of dental fluorosis and dental caries in
students from a public school in the city of Manaus, Amazonas. This is an observational,
analytical, descriptive, and cross-sectional study conducted with 212 schoolchildren aged 6
to 11 years from Escola Municipal Agenor Ferreira Lima. The clinical examination was
performed in the school environment using a dental mirror and a probe recommended by
the World Health Organization (WHO). Dental fluorosis was diagnosed using Dean’s Index,
and dental caries was assessed using the DMFT index. Statistical analysis included
descriptive procedures and association tests, adopting a significance level of p < 0,05.
Among the participants, 54.29% were female, and 43.6% were 8 years old. The prevalence
of fluorosis was 25%, with a predominance of very mild and mild degrees, while the
prevalence of dental caries was 46.2%. A statistically significant association was observed
between fluorosis and sex (p = 0.014), with higher occurrence in girls. No statistically
significant associations were found between fluorosis and age (p = 0.063), nor between
dental caries and fluorosis (p = 0.689), indicating that the presence of fluorosis does not
imply additional protection against caries. The results highlight the need for continuous
monitoring of fluoride exposure to ensure its preventive benefits against dental caries while
reducing the risk and severity of fluorosis.
Diagnóstico de carcinoma espinocelular moderadamente diferenciado HPV associado em paciente senil: relato de caso
(Universidade do Estado doAmazonas, 2025-12-10) Paiva, Eduarda Alves; Cabral, Lioney Nobre; http://lattes.cnpq.br/8956633114853772; http://lattes.cnpq.br/1321131301127268; Cabral, Lioney Nobre; http://lattes.cnpq.br/8956633114853772; Barroso, Mara Lilian Sevalho; http://lattes.cnpq.br/3480508540885994; Vasconcelos II, Antônio Jorge Araújo de; http://lattes.cnpq.br/5548562970182242
Squamous cell carcinoma (SCC) is a common malignancy in the head and neck region,
accounting for more than 90% of cases of oral malignancies. Human papillomavirus (HPV) is a
double-stranded virus belonging to the papillomaviridae family that lives in the cutaneous and
mucosal epithelium due to its specific tropism for epithelium. More than 200 types of HPV have
been described, but not all are related to oral cavity disease. High-risk HPV types are
associated with dysplasia and SCC, especially HPV16 and 18. The objective of this study is to
report the diagnosis of moderately differentiated SCC associated with HPV in a senile patient,
with the aid of immunohistochemistry, since histopathological examination alone was not
sufficient to confirm the viral etiology of the malignancy. A 67-year-old female patient was
referred to the POUEA stomatology clinic, presenting clinically with a leukoerythroplastic lesion
of lichenoid pattern measuring approximately 2 cm in the anterior 2/3 of the right lateral border
of the tongue, with an ulcer in the center. An incisional biopsy was performed and the
histopathological report showed moderately differentiated SCC. Immunohistochemical analysis
was recommended, where the biomarkers PanCK, P16 and P53 tested positive and Ki-67 had
a rate of 40%, which certified HPV as the etiological agent of the malignancy.
Presença do cirurgião-dentista em unidade hospitalar e o atendimento de paciente com epilepsia: relato de caso.
(Universidade do Estado do Amazonas, 2025-12-03) Pereira, Eduardo Braga; Ribeiro, Eliane de Oliveira Aranha; http://lattes.cnpq.br/0335350245760195; http://lattes.cnpq.br/3079848957874739; Ribeiro, Eliane de Oliveira Aranha; http://lattes.cnpq.br/0335350245760195; Prestes, Gimol Benchimol Resende; http://lattes.cnpq.br/1760015687924411; Brum, Joelson Rodrigues; http://lattes.cnpq.br/0257556911502691
Hospital dentistry encompasses specific actions of prevention, diagnosis, and treatment aimed
mainly at managing patients with systemic complications, in whom the risk of oral alterations
increases considerably. This study aimed to describe the relevance of the dentist’s role in the
hospital setting through the clinical case report of a patient with epilepsy admitted to a hospital
ward. The methodology consisted of an interview with the patient’s guardian, analysis of
laboratory tests from the medical record, and bedside clinical evaluation, followed by dental
intervention carried out by the Hospital Dentistry Extension Project team from the State
University of Amazonas. The patient, a 36-year-old male, presented with drug-induced gingival
hyperplasia, xerostomia, biofilm accumulation, and severe motor limitations. Supragingival and
subgingival scaling, prophylaxis, topical fluoride application, and oral hygiene instructions were
provided to the nursing staff and caregivers. During periodontal scaling, physical restraint using
a sheet was required to ensure the patient’s safety and stability throughout the procedure. The
results showed reduced dental plaque, improved gingival contour, and better bleeding control.
The case highlights that the continuous use of anticonvulsants in hospitalized patients with
epilepsy increases their vulnerability to oral alterations, reinforcing that the presence of a dentist
within the multidisciplinary team is essential. Furthermore, the case emphasizes the importance
of expanding and standardizing hospital dentistry, especially within the Unified Health System
(SUS), to ensure efficient and continuous care for patients with complex systemic conditions
such as epilepsy.
Hipomineralização molar incisivo em escolares da zona oeste de Manaus/AM.
(Universidade do Estado do Amazonas, 2025-11-24) Santos, Elson Silva dos; Pinto, Adriana Beatriz Silveira; http://lattes.cnpq.br/6500412100135501; http://lattes.cnpq.br/5303758486676316; Pinto, Adriana Beatriz Silveira; http://lattes.cnpq.br/6500412100135501; Dutra, André Luiz Tannus; http://lattes.cnpq.br/6531187568170608; Carvalhal, Cíntia Iara Oda; http://lattes.cnpq.br/8821156090928265
This study aims to evaluate the prevalence of Molar–Incisor Hypomineralization (MIH) in
elementary school students from Manaus, Amazonas. This is an observational, analytical,
descriptive, and cross-sectional study conducted with students enrolled in a public elementary
school located in the western region of Manaus, Amazonas. The clinical examination was
carried out after examiner calibration, and oral cavity assessment was performed using
disposable wooden spatulas and individually pre-sterilized clinical instruments. To assess
dental caries, the dmft/DMFT index was used according to the criteria established for SB 2023.
MIH was evaluated following the criteria proposed by Ghanim et al. (2015). For statistical
analysis, the variables related to the presence of MIH were considered dependent, while all
other variables were treated as independent. A total of 103 students participated in the study,
of whom 59.2% were female, with a mean age of 9.5 years. The prevalence of MIH was 10.7%,
while 24.3% of the students presented fluorosis. The mean dmft/DMFT index was 1.14, with
61.2% of the students being caries-free. There was no statistically significant association
between MIH and dental caries (p = 0.394), nor between MIH and sex (p = 0.738). It is
concluded that fluorosis was the most prevalent enamel defect among students in the western
region of Manaus, followed by MIH and demarcated opacities. No significant association was
found between MIH and the variables dental caries or sex.
Prevalência de defeitos de desenvolvimento do esmalte dentário em escolares da zona lesta de Manaus - Am
(Universidade do Estado do Amazonas, 2025-11-24) Bezerra, Gabriela Pinto; Pinto, Adriana Beatriz Silveira; http://lattes.cnpq.br/6500412100135501; http://lattes.cnpq.br/5336941113080541; Pinto, Adriana Beatriz Silveira; http://lattes.cnpq.br/6500412100135501; Dutra, André Luiz Tannus; http://lattes.cnpq.br/6531187568170608; Carvalhal, Cíntia Iara Oda; http://lattes.cnpq.br/8821156090928265
Developmental Enamel Defects (DED) are manifestations of structural failures resulting from
a disturbance occurring in one of the stages of amelogenesis. The objective of this study is
to establish the prevalence and severity of DED and the dental caries experience among
schoolchildren aged 6 to 15 years enrolled in public schools in the eastern zone of Manaus,
Amazonas. This is an observational, analytical, cross-sectional, and descriptive study. The
sample consisted of 750 students from six different schools. Data collection was carried out
through na epidemiological clinical examination in the school environment, performed by a
calibrated examiner, using artificial light, a wooden spatula, a No. 5 dental mirror, and
periodontal WHO probe. After the individual examination, data were recorded on forms
including DED, dental fluorosis severity, and dmft/DMFT index. Statistical analysis was
performed using the Chi-square test and Student’s t-test. This study was approved by the
Research Ethics Committee of the State University of Amazonas, under protocol CAAE
79453124.1.0000.5016. Data analysis revealed that 20.3% (152) of the schoolchildren
presented some type of DED, with dental fluorosis being the most prevalent, representing
8.4% of this group. Additionally, 4.5% presented Molar–Incisor Hypomineralization (MIH),
while 3.7% showed others enamel opacities. Dental fluorosis was observed in 10% of the
total sample and classified according to Dean’s Index, which indicated that 5.1% presented
very mild fluorosis, 4.3% mild, and 0.7% moderate. Dental caries was present in 48% of the
analyzed sample, with the “decayed” component being the most prevalent. There was no
statistically significant association between DED and dental caries. Enamel defects were
found in 20.3% of the schoolchildren, with dental fluorosis being the most common (8.4%),
followed by MIH (4.5%) and opacities (3.7%). Dental caries experience was present in 48%
of the studied population. Therefore, the present study highlights the importance of regional
epidemiological investigation of Developmental Enamel Defects, enabling the training of
professionals prepared to carry out early clinical intervention, minimize sequelae, and
improve the oral health of affected individuals.
