Estudio de las caracteristicas de oclusión de niños de 12 años del municipio de Cáceres, Mato Grosso, Brasil

The aim of this study was to evaluate the occlusal condition of 12 year-old children examined by the Oral Health Brazil 2003 Project in Cáceres city. The sample consisted of 170 children, boys and girls, selected at random among 20 schools that took part in this project. It was used for the analysis of the occlusal condition the Dental Aesthetic Index (DAI), as manual of basic epidemic rising in Oral Health extolled by the World Health Organization which describes the occlusal conditions in relation to dentition, space and occlusion of the permanent dentition. It was observed that the prevalence of the normal occlusion and of the malocclusion were, respectively, 21.18% and 78.82%. This last one was present due to the tooth crowding (74.93%), spacing in the incisor segment (23.88%), diastema (17.17%), anterior maxillary misalignment (58.95%) and anterior mandibular (61.19%), excessive overjet (11.94%), negative overjet (4.47%), open bite (1.5%) and molar relationship Class II or III (26.87%). It was concluded that the studied sample presents a high index of factors to compose the malocclusion.

Actinic Cheilitis: epidemiological study in a riverine population of northern Brazil

AIM: The aim of this survey was to assess the prevalence of AC in riverine population in countryside of Amazonas, northern Brazil. MATERIAL AND METHODS: Patients answered a questionnaire and were examined between January and December of 2008. Data were gathered on the following participant’s characteristics: 1) age group; 2) gender; 3) ethnicity 4) outdoor activities (sunlight exposure); 5) smoking habits; 6) drinking habits; and 7) access to oral health services (the last dental visit). Clinical observation of the lips for determination of AC presence was used. Patients who presented clinical manifestation of moderate and severe AC were submitted to incisional biopsy to confirm the diagnosis. In case of a positive result after histopathological examination, patients were advised and appropriate treatment was offered. All patients received information about AC and its'prevention. RESULTS: Among the 200 participants that were examined, the prevalence of AC was 2% (4 cases). Of all patients surveyed, women were the majority totalizing 124 patients (72.0%). According to age, 48 (24.0%) people were 20g34 yeargold; 42 (21.0%) were 35g44gyeargold; 50 (25.0%) were 45g60gyeargold; and 60 (30.0%) were 61 or older. CONCLUSION: Even though AC was present in a low prevalence rate, an epidemiological variety is expected, once geographic and ethnic differences should be considered.

Dental caries related to quality of life in two Brazilian adolescent groups: a cross-sectional randomised study

Objectives: To analyse dental caries-related quality of life (QoL) in adolescent (1519-year-old) subjects in a suburban area (SA) and a downtown area (DA) of Bauru, Sao Paulo, Brazil, in 2009. Methods: This was a cross-sectional, randomised study. The sample consisted of 185 and 147 adolescents from the SA and DA, respectively. The caries index used was that for decayed, missing and filled teeth (DMFT) (World Health Organization criteria). The 14-item Oral Health Impact Profile (OHIP-14) was used to assess QoL. The non-parametric MannWhitney test, Spearmans correlation coefficient and chi-squared test were used in the statistical analysis. Results: The DMFT index, Significant Caries (SiC) Index and percentage of caries-free students were similar (P > 0.05) between these populations, but findings on the Care Index differed (P < 0.05). There was a correlation between the DMFT index and OHIP-14 score in SA subjects (mean DMFT index = 3.01) in the dimensions of physical pain (r = 0.25; P < 0.01) and psychological disability (r = 0.17; P = 0.02). The DMFT index in DA subjects (mean DMFT index = 2.95) showed a correlation with functional limitation (r = 0.19; P = 0.02). The correlation in SA subjects between the caries component (mean = 1.22) of the DMFT index and OHIP-14 was significant only for the physical pain dimension (r = 0.16; P = 0.03). In DA subjects, correlations between the caries component (mean = 0.37) and all dimensions of OHIP-14 were statistically significant (P < 0.05). Conclusions: Despite the similarities in means in the DMFT index, the SiC Index and the caries-free percentage of subjects in both localities, access to dental treatment proved to be less effective for SA adolescents. Physical pain and psychological disability were the most frequent negative manifestations of impact on QoL. The SA adolescents were more negatively affected by dental caries in terms of QoL.

Micronucleus frequency in children exposed to biomass burning in the Brazilian Legal Amazon region: a control case study

Background: The Amazon represents an area of 61% of Brazilian territory and is undergoing major changes resulting from disorderly economic development, especially the advance of agribusiness. Composition of the atmosphere is controlled by several natural and anthropogenic processes, and emission from biomass burning is one with the major impact on human health. The aim of this study was to evaluate genotoxic potential of air pollutants generated by biomass burning through micronucleus assay in exfoliated buccal cells of schoolchildren in the Brazilian Amazon region. Methods: The study was conducted during the dry seasons in two regions of the Brazilian Amazon. The assay was carried out on buccal epithelial cells of 574 schoolchildren between 6-16 years old. Results: The results show a significant difference between micronucleus frequencies in children exposed to biomass burning compared to those in a control area. Conclusions: The present study demonstrated that in situ biomonitoring using a sensitive and low cost assay (buccal micronucleus assay) may be an important tool for monitoring air quality in remote regions. It is difficult to attribute the increase in micronuclei frequency observed in our study to any specific toxic element integrated in the particulate matters. However, the contribution of the present study lies in the evidence that increased exposure to fine particulate matter generates an increased micronuclei frequency in oral epithelial cells of schoolchildren.

Contextual and individual inequalities in dental pain prevalence among Brazilian adults and elders

This study aimed to assess the prevalence of dental pain among adults and older people living in Brazil's State capitals. Information was gathered from the Telephone Survey Surveillance System for Risk and Protective Factors for Chronic Diseases (VIGITEL) in 2009 (n = 54,367). Dental pain was the outcome. Geographic region, age, gender, race, schooling, private health coverage, smoking, and soft drink consumption were the explanatory variables. Multilevel Poisson regression models were performed. Prevalence of dental pain was 15.2%; Macapa and Sao Luis had prevalence rates greater than 20%; all capitals in the South and Southeast, plus Cuiaba, Campo Grande, Maceio, Recife, and Natal had prevalence rates less than 15%. Factors associated with increased prevalence of dental pain were the North and Northeast regions, female gender, black/brown skin color, lack of private health insurance, smoking, and soft drink consumption. Dental pain is a public health problem that should be monitored by health surveillance systems.

Molecular detection of in-vivo microbial contamination of metallic orthodontic brackets by checkerboard DNA-DNA hybridization

Introduction: Knowing the microbiota that colonizes orthodontic appliances is important for planning strategies and implementing specific preventive measures during treatment. The purpose of this clinical trial was to evaluate in vivo the contamination of metallic orthodontic brackets with 40 DNA probes for different bacterial species by using the checkerboard DNA-DNA hybridization (CDDH) technique. Methods: Eighteen patients, 11 to 29 years of age having fixed orthodontic treatment, were enrolled in the study. Each subject had 2 new metallic brackets bonded to different premolars in a randomized manner. After 30 days, the brackets were removed and processed for analysis by CDDH. Data on bacterial contamination were analyzed descriptively and with the Kruskal-Wallis and Dunn post tests (alpha = 0.05). Forty microbial species (cariogenic microorganisms, bacteria of the purple, yellow, green, orange complexes, "red complex + Treponema socranskii," and the cluster of Actinomyces) were assessed. Results: Most bacterial species were present in all subjects, except for Streptococcus constellatus, Campylobacter rectus, Tannerella forsythia, T socranskii, and Lactobacillus acidophillus (94.4%), Propionibacterium acnes I and Eubacterium nodatum (88.9%), and Treponema denticola (77.8%). Among the cariogenic microorganisms, Streptococcus mutans and Streptococcus sobrinus were found in larger numbers than L acidophillus and Lactobacillus casei (P < 0.001). The periodontal pathogens of the orange complex were detected in larger numbers than those of the "red complex + T socranskii" (P < 0.0001). Among the bacteria not associated with specific pathologies, Veillonella parvula (purple complex) was the most frequently detected strain (P < 0.0001). The numbers of yellow and green complex bacteria and the cluster of Actinomyces were similar (P > 0.05). Conclusions: Metallic brackets in use for 1 month were multi-colonized by several bacterial species, including cariogenic microorganisms and periodontal pathogens, reinforcing the need for meticulous oral hygiene and additional preventive measures to maintain oral health in orthodontic patients.
