Item Association Between Somali Mothers' Oral Health Literacy and Their Children's Caries Experience in Minnesota(2019-07) Zeyer, KyleeABSTRACT Objectives: Dental caries is a major oral health problem among U.S. immigrant children, and Minnesota is home to one of the largest Somali-American communities, but little is known about this population’s oral health and oral health literacy. Therefore, the purpose of this study was to investigate the association between Somali mothers’ oral health literacy and their children’s caries experience in the Minneapolis and St. Paul areas in Minnesota. Methods: A retrospective cross-sectional study was performed. Data were extracted from a larger cross-sectional study consisting of 99 Somali mothers and 292 children from twelve Somali-owned daycare centers in 3 Minnesota cities. Participating mothers completed an oral health literacy survey (HeLD-14), and mothers and their children received oral screenings where caries experience was recorded using the dfs/DMFS caries indices. Results: Mean age in years was 34.3 for mothers and 6.4 for children. Mothers had moderate oral health literacy with a mean HeLD-14 score of 8.4. The children’s mean dfs score was 3.3, and their mean DMFS score was 0.8. The children’s caries was not associated with the mothers’ total oral health literacy score, although, statistically significant associations were found between 3 of 7 HeLD-14 subcategories: access to care, receptivity, and economic barriers. Conclusions: Somali children’s caries experience was similar to U.S.-born comparatives, but lower than African-American children of similar age. Given, the children’s below average caries experience and the mothers’ moderate level of oral health literacy, may be an indicator that this population does not suffer from oral health disparities related to the oral health literacy and caries experience of mother-child pairs.

While clinical examination provides important information in the diagnosis of periodontal disease and caries, bitewing radiography is one of the tools used for the examination of structures that cannot be readily seen with the naked eye. The ProMax S3 panoramic unit from Planmeca offers a True Bitewing program that can obtain bitewing images without the use of intraoral sensors. The aims of this study was to compare the diagnostic accuracy of intraoral bitewings and extraoral bitewings for the detection of 1. interproximal caries 2. interproximal bone loss Methods: Patients from the University of Minnesota School of Dentistry who recently received intraoral bitewings were recruited for extraoral bitewings. Five examiners (two board certified radiologists, one radiology clinical assistant professor, one general dentist and one graduate periodontics resident) evaluated both images for interproximal bone loss and interproximal caries as well as a consensus diagnosis was made. Results: The study population was one hundred sixteen patients. There was statistically significantly greater caries detection with extraoral radiographs (46.26% of surfaces) compared to intraoral radiographs (21.12% of surfaces) at p<0.0001. Assuming that the intraoral bitewing is the gold standard, for caries diagnosis, the extraoral bitewings had a sensitivity of 71.91% and a specificity of 61.99% with a false positive rate of 38.01%. When evaluating the bone loss detection, there was statistically significantly greater detection with extraoral bitewings (90.19% of teeth) compared to intraoral bitewings (77.95% of teeth) at p<0.0001. Assuming that the intraoral bitewing is the gold standard, for bone loss diagnosis, the extraoral bitewings had a sensitivity of 94.5% and a specificity of 26.86% with a false positive rate of 73.14%. Conclusions: The caries detection rate with extraoral bitewings was significantly greater than intraoral bitewings. The false-positive rate for caries detection with extraoral bitewings was 38.01%. The bone loss detection rate with extraoral bitewings was also significantly greater than intraoral bitewings. The false-positive rate for bone loss detection with extraoral bitewings was 73.14%. While extraoral bitewings provide efficient imaging with more patient comfort, it appeared to have more false positives, which would warrant cross-examination with clinical exams and re-evaluation with follow up exams.
