Material and Methods: A longitudinal study was conducted on women with breast cancer at a Hospital reference, Espirito Santo, Brazil from January 2012 to January 2013. Assessment was performed at three time-points, the first before the onset of therapeutic intervention, the second after the first chemotherapy session, and the third after the second chemotherapy session. The volunteers were assessed using interviews that included the application of the subjective indicator Oral Health Impact Profile (OHIP-14). The data were subjected to descriptive analysis based on tables of absolute and percentage frequencies relative to the OHIP-14 dimensions. McNemar’s test assessed the direction of discordance, and the Kappa test measured the levels of concordance among the three assessments. The significance level was established at 5%. Results: The percent frequency of the impact of oral problems on the quality of life increased from the first (27%) to the second (49%) time-point, and functional limitation (p=0.001), physical pain (p=0.039), and physical disability (p=0.039) were statistically significant. Conclusion: Oral problems exerted a substantial impact on the volunteers’ quality of life before the onset of chemotherapy, and quality of life became poorer after the onset of treatment. Patients with breast cancer require specific oral care and should be monitored before, during, and after anticancer treatment to minimize the deleterious effects of chemotherapy and improve their quality of life.","PeriodicalId":134552,"journal":{"name":"Brazilian Research in Pediatric Dentistry and Integrated Clinic","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125956828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinical and bitewing radiographic examinations were performed by a calibrated examiner, as well as the filling of the adapted CAMBRA form. Dental caries disease indicators, risk factors and protective factors of all subjects were determined. Chi-square test and multivariate logistic regression analysis for all CAMBRA variables were applied (p<0.05). Results: Caries risk was considered high in 38.2% of patients, moderate in 32.6% and low in 29.6%. The most frequent disease indicator was white spot lesion on smooth surfaces (73.0%), the most common risk factor was visible biofilm (78.7%) and protective factor was fluoridated water (100.0%). Children with “moderate risk” and “high risk” had risk of visible cavities or radiographic penetration of the dentin (OR=14.689; OR=574.363, respectively) compared to patients with “low risk”. Conclusion: Caries risk determined as “high” and “moderate” were classifications most observed among children attending BHU.

Results: Of the 200 interviewed dentists, 66% (n=132) were women, the prevalent age group was 21-40 years (49.5%), 47% work at the private sector and 39% concluded their graduation 20 years ago.
