Objectives: This systematic review investigated the prevalence of tooth wear between patients with and without Down syndrome. Methods: Six databases (Embase, LILACS, Livivo, PubMed, Scopus and Web of Science) and grey literature (Google Scholar, OpenGrey and ProQuest) were searched until March 7, 2022. Observational studies were included to assess the differences in tooth wear prevalence and/or severity in Down syndrome and non-syndromic controls. Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) recommendations were followed. Three reviewers independently screened studies, extracted data, assessed the methodological quality (Joanna Briggs Institute) and graded the certainty of evidence through the Grading of Recommendations, Assessment, Development, Evaluation (GRADE) approach. Results were summarized through meta-analyses using a random-effects model. The protocol was registered at PROSPERO (CRD42021266997). Results: Of the 1382 records identified, six cross-sectional studies were included. Individuals with Down syndrome had a higher prevalence and were more likely to have tooth wear than individuals without Down syndrome (44% × 15%; OR = 4.43; 95% CI 3.17–6.18; p < 0.00001; I2 = 8%). Also, the severity of tooth wear was higher in the Down syndrome group (n = 275) compared with the controls (n = 294). The certainty of evidence analysis was very low. Conclusions: Based on very low certainty of the evidence, patients with Down syndrome had a higher prevalence and likelihood and severity of tooth wear when compared to those without Down syndrome. Clinical relevance: Screening early tooth wear lesions should be carefully done in the Down syndrome population since its occurrence is remarkable compared to the general population.

Objectives: To test 8 models of linear surface roughness assessment in characterizing surface profile description and to correlate these models with equivalent areal parameters over sound human enamel in vitro. Materials and methods: Thirty enamel blocks were randomly selected. The roughness data (2D—Rp; Rv; Rz; Rc; Rt; Ra; Rq; Rsk; Rku/3D—Sp; Sv; Sz; Sa; Sq; Ssk; Sku) was obtained in duplicate in a non-contact 3D optical profilometer. The models were composed by 1 single vertical trace (model 1) until 8 traces (model 8 composed by three vertical traces, three horizontal traces, and two diagonal). Results: The addition of linear sampling traces to the enamel blocks did not result in Rp, Rv, Rz, Rc, Rt, Ra, Rq, Rsk, and Rku value changes (low power—from 5 to 72%). Significant Spearman's correlation coefficients were obtained in most correlation analysis (Rp ↔ Sp; Rv ↔ Sv; Rz ↔ Sz; Ra ↔ Sa; Rq ↔ Sq; and Rku ↔ Sku). Conclusions: A single vertical trace in the middle of the sample was representative of the overall enamel surface roughness (Rp, Rv, Rz, Rc, Rt, Ra, Rq, Rsk, and Rku) models. The majority of the assessed models in the correlation evaluation presented significant and positive association. Clinical relevance: The findings highlight the applicable model for roughness analysis over human enamel recommended for research and in situ trials assessments. [ABSTRACT FROM AUTHOR]

Oral health education is an effective measure to prevent oral mucositis (OM) by improving self-management and effectively engaging patients in their health care. This systematic review aimed to determine the impact of oral health education interventions on the incidence and severity of OM. Bibliographical searches were carried out by two independent examiners in Medline, Scopus, Web of Science, Cochrane Library, Virtual Health Library, and SIGLE, until June 2022. The eligibility criteria were based on the PICO strategy, considering studies with pediatric oncology patients, aged 0 to 19 years, who had attended oral health education activities and had been examined for the incidence and/or severity of OM. Data were extracted for qualitative synthesis and organized in spreadsheets. The quality assessment of the selected studies was performed using the ROBINS-I tool. Meta-analysis was based on the group frequencies of OM ulcerative lesions, adopting a significance level of 5%. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was used to define the certainty of the evidence. The primary search retrieved 1827 articles. After removing duplicate records and screening titles and abstracts for eligibility, a total of 21 articles were selected for full-text analysis. Of these, seven eligible studies were included for data extraction and qualitative synthesis, while four studies were selected for quantitative synthesis. All studies had a longitudinal design; three performed a before-after comparison and four were controlled studies. OM was assessed by the following scales: OAG, WHO, ChIMES, and WCCNR. While data analysis of the selected studies was heterogeneous, the implementation of oral health education strategies was found to reduce the incidence and severity of OM during the follow-up period. The meta-analysis showed a favorable outcome for the educational intervention. The likelihood of patients attending oral health education activities to manifest OM ulcerative lesions was significantly lower (P = 0.002) than that of the control. The GRADE analysis presented a low certainty of the evidence. To conclude, oral health education interventions improved OM outcomes in pediatric oncology patients with a low quality of evidence.
