Chronic inflammatory periapical diseases: a Brazilian multicenter study of 10,381 cases and literature review.

The aim of this study was to investigate the epidemiological and clinical characteristics of chronic inflammatory periapical diseases in different regions of Brazil and to compare with data from the literature. A multicenter study was carried out in four Brazilian referral centers in oral diagnosis. Histopathological records were reviewed, and all cases diagnosed microscopically as periapical granuloma, radicular cyst, and periapical abscess were included. Demographic and clinical data were collected. Descriptive statistics and Pearson's chi-square test were performed. A total of 10,381 cases of chronic inflammatory periapical diseases were found (13.8% of 74,931 archived specimens) over a period of 65 years. Radicular cysts were the most common lesion (59.9%). Women (56.1%) with a mean age of 37.01 years old (range 13 to 100 ± 14.42) and people of white skin color (59.2%) were the most affected individuals by chronic inflammatory periapical diseases. The lesions were generally asymptomatic (28.1%), located in the maxilla (60.1%), and posterior region (49.8%). The radicular cysts were larger when compared to periapical granulomas (p < 0.001). The disagreement between the clinical and histopathological diagnoses was higher when the final diagnosis was a periapical granuloma (p < 0.001). Chronic inflammatory periapical diseases continue to be common lesions affecting mainly adults. This should be a consequence of the burden of untreated caries in permanent teeth. Women are more affected and radicular cyst was the most common lesion.

O uso do fio dental reduz a ocorrência de sangramento gengival? / Does dental flossing reduce the occurrence of gingival bleeding?

Objetivos: tendo em vista a relevância da prevenção à gengivite, e consequentemente à periodontite, e a falta de consenso na literatura sobre a efetividade do fio dental como medida protetora ao sangramento gengival, este artigo buscou revisar a literatura objetivando responder a seguinte pergunta: "O uso do fio dental é efetivo para prevenir o sangramento gengival?". Material e métodos: revisões sistemáticas foram buscadas na base de dados Pubmed, sem limite de data e de linguagem. Resultados: duas revisões foram encontradas, e seus resultados foram sumarizados. Conclusão: a literatura científica sugere que o uso do fio dental associado à escovação é adequado para o controle do biofilme, e consequentemente, do sangramento gengival. Entretanto, essa evidência apresenta inúmeras limitações, e seus resultados precisam ser confirmados. Assim, são necessários mais estudos que demonstrem claramente o efeito do fio dental sobre o sangramento gengival.

Objectives: given the relevance of gingivitis prevention, and consequently periodontitis, and the lack of consensus in the literature on the effectiveness of dental floss as a protective measure of gingival bleeding, this article aimed to revise the literature in order to answer the following question: Is flossing effective in preventing gum bleeding? Material and methods: systematic reviews were searched on Pubmed database, with no limits for date and language. Results: two reviews were found, and their results were summarized. Conclusion: the scientific literature suggests that flossing associated with brushing is adequate for biofilm control, and consequently, for preventing gingival bleeding. However, this evidence has relevant limitations, therefore, these results need to be carefully considered. Thus, further studies are needed to clearly demonstrate the effect of dental floss on prevention of gingival bleeding.
