BackgroundHepatitis B infection is the major cause of acute and chronic liver disease, cirrhosis and hepatocellular carcinoma worldwide and has long been recognized as an occupational hazard among dentists. The aim of the present study was to examine factors associated to the self-reporting of hepatitis B vaccination and immunization status among dentists working in the city of Belo Horizonte, Brazil.MethodsA cross-sectional survey was carried out with 1302 dentists in Belo Horizonte, Brazil. After signing a term of informed consent, the participants answered a structured questionnaire on their knowledge regarding their vaccination and immunization status against hepatitis B. Data on demographic, behavioural and occupational exposure aspects were also collected through questionnaires.ResultsThe results revealed that 73.8% of the dentists reported having received three doses of the vaccine. Multivariate analysis revealed that gender (p = 0.006), use of individual protective equipment (p = 0.021), history of blood transfusion (p = 0.024) and history of illicit drug use (p = 0.013) were independently associated with vaccination against hepatitis B. Only 14.8% had performed a post-vaccination test. The use of individual protective equipment (p = 0.038), dentists who asked patients about hepatitis during dental treatment (p < 0.001), a family history of hepatitis B (p = 0.003) and work experience (p < 0.05) were independently associated with the post-vaccination test.ConclusionsAlthough there were a large number of vaccinated dentists in Belo Horizonte, the percentage was less than what was expected, as Brazil offers the National Program of Viral Hepatitis Vaccination, which provides free hepatitis B vaccinations to all healthcare workers. Despite being part of a high risk group for contamination, most of the dentists did not know their immunization status.
The aim of this study was to investigate factors associated with caries experience in the primary dentition of one-to five-year-old children with cerebral palsy. A total of 266 dental records were examined, and caries experience was measured by dmft. The following variables were also analyzed: gender, oral hygiene, history of gastroesophageal reflux, use of medications for gastroesophageal reflux, gingival status, sugar intake and reports of polyuria, excessive thirst and xerostomia. For analysis purposes, the individuals were categorized as those with and without caries experience and subcategorized into the following age groups: one year; two to three years; and four to five years. After bivariate analysis, variables with a p-value < 0.25 were selected for incorporation into the Poisson regression models. Considering the limitations of the protocol, the level of oral hygiene perceived on the first appointment was the only factor associated with caries experience among two-to-fiveyear-old children with cerebral palsy.
Möbius syndrome is a rare congenital condition that is characterized clinically by paralysis of a group of cranial nerves. It presents diverse manifestations that can have negative repercussions on the quality of life of affected individuals. This article presents a clinical case of a child with the syndrome and addressed the clinical manifestations and difficulties experienced during dental treatment. Knowledge of the etiopathological aspects and clinical manifestations of the condition is essential to perfecting treatments that aim to improve the quality of life of such individuals and their families.
The aim of the present study was to investigate factors associated with bruxism in children aged from 1 to 13 years with developmental disabilities. A total of 389 dental records were examined. The bruxism analyzed was determined based on parental reports. The following variables were also analyzed: gender, age, International Code of Diseases (ICD), mouth breathing, history of gastroesophageal reflux, use of psychotropic drugs, gingival status, reports of xerostomia, hyperkinesis, pacifier use, thumb sucking and involuntary movements. For the purposes of analysis, the individuals were categorized as being with and without bruxism. Variables with a p-value < 0.25 in the bivariate analysis were incorporated into the logistic regression models. Females had a 0.44-fold (95%CI: 0.25 to 0.78) greater chance of exhibiting bruxism than males. Individuals with gastroesophageal reflux had a 2.28-fold (95%CI: 1.03 to 5.02) greater chance of exhibiting bruxism. Individuals with reported involuntary movements had a 2.24-fold (95%CI: 1.19 to 4.24) greater chance of exhibiting bruxism than those without such movements. Exhibiting involuntary movements, the male gender and gastroesophageal reflux are factors associated with bruxism in children with developmental disabilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
