Introduction: Tooth decay is still a highly prevalent disease in populations. Because of this, epidemiological studies are carried out frequently and allow the monitoring of the experience of the disease. Objective: To estimate the prevalence of dental caries of 5 and 12-years-old schoolchildren in the cities of Florianópolis, Santa Catarina, and Porto Velho, Rondônia, as well as to search hypotheses of association with social/economic determinants and access to dental services. Material and methods: Secondary data were used from the Brazilian Oral Health Survey of 2010, as follows: household income by city and dmft/DMFT index for ages by city and region of Brazil. Results: It was observed in the city of Florianópolis a 5-years-old dmft of 1.56, and 12-years-old DMFT of 0.55. In Porto Velho the means were 2.89 and 4.15 to the respective age. It was found that in Porto Velho 89.5% of surveyed had family income up to R$2,500.00, while in Florianópolis 81.9% had R$501.00 to R$9,500.00. Conclusion: The city of Florianópolis had the best caries indices and socioeconomic conditions, suggesting an association between these variables, in detriment to the regions in the opposite situation.

A abertura coronária é a primeira etapa do tratamento endodôntico e visa ao acesso direto aos canais radiculares. Objetivo: Avaliar as aberturas endodônticas de dentes de pacientes referenciados ao Centro de Especialidades Odontológicas (CEO) Positivo, na cidade de Curitiba (PR), por análise radiográfica. Material e métodos: Um total de 226 radiografias periapicais tomadas previamente ao atendimento no CEO, de agosto de 2015 a agosto de 2017, foi analisado. Três examinadores treinados e calibrados verificaram os seguintes critérios: região da cavidade bucal, cárie remanescente, remoção do teto da câmara pulpar, desgaste compensatório mesiodistal, iatrogenia (sugestiva) e restauração temporária. Os dados foram tabulados e analisados quanto à distribuição, seguida de análise bivariada (Teste Exato de Fisher) com significância de 5%. Resultados: A região posterior prevaleceu em 70,3% da amostra. Constataram-se cárie remanescente em 14,2%, remoção insuficiente do teto em 25,2%, iatrogenia em 31,4% e altura inadequada da restauração temporária em 11,5% dos casos. Nos dentes posteriores, o desgaste compensatório mesiodistal insuficiente foi identificado em 35,4% dos exames. A análise bivariada não revelou diferença significativa quando verificada a variável região da cavidade bucal em relação a presença de cárie (p = 0,393), teto remanescente (p = 0,056) e presença de iatrogenia (p = 0,304). Conclusão: Há falhas relevantes nas aberturas endodônticas recebidas no CEO, o que indica a necessidade de treinamento profissional na atenção primária.

Introduction: Coronary access is the first stage of endodontic treatment and aims at direct access to root canals. Objective: To evaluate, by radiographic analysis, endodontic access cavities through radiographic analysis of the teeth of patients coming from primary care referred to the Center of Dental Specialties (CEO) Positivo, Curitiba, PR, Brazil. Material and methods: A total of 226 periapical radiographs taken previous to attending the CDS were analyzed, from August 2015 to August 2017. Three trained and calibrated examiners verified the following criteria: oral cavity region, presence of remaining caries,removal of roof of the pulp chamber, compensatory mesiodistal wear, iatrogenic (suggestive) and temporary restoration. Data were tabulated and analyzed for distribution, followed by bivariate analysis (Fisher’s Exact Test) with significance of 5%. Results: The posterior region prevailed in 70.3% of the sample. There remaining caries were found in 14.2%, insufficient roof removal in 25.2%, iatrogenic in 35.4%, and inadequate height of the temporary restoration in 11.5% of the cases. In the posterior teeth, insufficient mesiodistal compensatory wear was identified in 35.4 of the exams. The bivariate analysis revealed no significant difference when the variable region of the oral cavity was analyzed in relation to the presence of caries (p = 0.393), remaining roof (p = 0.056) and presence of iatrogenic (p = 0.304). Conclusion: It is concluded that there are relevant failures in the endodontic access received in the CDS, which indicates the need for professional training in primary care.

The aim of this study was to analyze the prevalence and to georeference the malocclusion traits in adolescents in the city of Curitiba, Paraná, Brazil. Data from a previous cross-sectional study with 538 adolescents aged 10 to 14 years were used. In addition, the following variables were used: gender, Health District (HD) of residence, and presence and malocclusion traits. Fisher’s Exact Test, georeferencing, and kernel mapping were used for data evaluation. Malocclusion was observed in 52.4% of individuals, and the most prevalent occlusal trait was deep bite (22.7%), followed by excessive overjet (19.9%), anterior crowding (8.0%), posterior crossbite (6.5%), anterior open bite (4.8%), and anterior crossbite (1.7%). Malocclusion was not associated with gender (p = 0.389) or HD (p = 0.079). However, when stratified by gender, the deep bite prevailed among male. The highest malocclusion trait’s prevalence was observed in the HDs of Cajuru, Pinheirinho, Boa Vista, and Cidade Industrial de Curitiba. Despite the absence of significant differences in relation to gender and HD, the prevalence of malocclusion traits in the sample studied was high, especially for deep bite. Additionally, georeferencing proved to be useful for identifying the distribution of malocclusion in Curitiba.
