The primary objective is to explore the existing research and epidemiological studies on the burden of periodontal diseases, particularly their impact on oral health-related quality of life (OHRQoL) and associations with systemic health conditions in Latin America and the Caribbean (LAC). An electronic literature search was conducted across multiple databases, including MEDLINE (PubMed), Scopus, LILACS, SciELO, and Web of Science, without publication date or language limitations, up until December 2023. Reviewers independently assessed titles and abstracts based on the eligibility criteria. The search yielded 1195 articles, with 63 meeting the inclusion criteria. The results of epidemiological studies showed that periodontitis is extremely prevalent at 90% in LAC; severe periodontitis can affect nearly 10% of the adult population and that periodontitis is aggravated by smoking, poverty, low education level, and limited access to proper dental care. Periodontitis was consistently associated with worse OHRQoL; and causing pain, and/or triggering psychological discomfort, physical disability, and social disability. Associations were also reported between periodontitis and comorbidities such as diabetes, cardiovascular disease, rheumatoid arthritis, respiratory disease, mental illness, and adverse pregnancy outcomes that are also affecting the quality of life of individuals and their families.

Five years after the first version, knowledge has increased, and diagnosis of periodontal disease has evolved. Of especial interest relative to this topic has been the emergence of studies that have used the AAP/EFP Classification of Periodontal and Peri-Implant Diseases and Conditions since it is the core (?)of the art of diagnosis in preventive and therapeutic strategies. To make an accurate and effective diagnosis, knowledge about the health-disease process is fundamental. This article updates and demonstrates challenges in periodontal diagnosis, especially in Latin American countries. Considering that periodontal diagnosis should be based on knowledge of the etiopathogenesis of periodontal diseases, this article points out aspects developed in the last few years and emphasizes the knowledge that has been established, considering diagnosis of periodontal diseases. The evidence available stresses the importance of interviewing the patient, by implementing periodontal charting, and requesting any imaging and other complementary tests necessary. An important observation is that the partial periodontal data recordings used for screening (up to now) are not diagnostic methods and might underestimate disease. Moreover, in this article approaches to other forms of recognizing periodontal diseases are described, which could be used, however, not for the purpose of diagnosis, but for increasing awareness and eventually for referring individuals. In Latin American countries there is a need to increase the awareness of periodontal diseases among both the population and the profession, with particular emphasis on prioritizing correct periodontal diagnosis. In Dental education, strategies need to be established with the purpose of understanding that diagnosis is pivotal to any clinical approach.</p>","PeriodicalId":9240,"journal":{"name":"Brazilian oral research","volume":"38 suppl 1","pages":"e119"},"PeriodicalIF":1.5,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11665972/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142738441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The countries with nationally representative studies were Brazil, Chile, Colombia, and Uruguay. The prevalence of periodontal disease or need for periodontal treatment varied between the different studies and countries depending on the age group, the methodology used, and the case definition. The prevalence of severe periodontitis aged between 5.8% and 49.7% in adults. In adolescents, the prevalence of moderate to severe periodontitis was 15.3%. Furthermore, a high prevalence of gingival bleeding in adolescents was reported. When analyzing the studies that used the Community Periodontal Index (CPI), Centers for Diseases Control and American Academy Periodontology (CDC/AAP) case definition, it was observed that as the age of the individuals analyzed increased, the prevalence of periodontal disease also increased.

Comprehending these findings is crucial, as high PD-L1 expression in the tumor microenvironment of OPSCC can help identify patient subgroups that could be suitable for immunotherapy. Therefore, a systematic review was conducted following PRISMA guidelines (CRD42023437800). An electronic literature search was performed without time or language restrictions.

This scoping review complies with PRISMA-ScR. It was customized to assess the risk of bias of the included studies, and was registered on the Open Science Framework platform. The data extraction protocol was developed based on the PCC acronym. An electronic search was conducted in six databases (Pubmed, Web of Science, Scopus, Embase, Lilacs, Cochrane) in December 2023. Original articles were screened, having observational, diagnostic accuracy, and consisting of in vivo or ex vivo laboratory studies investigating the influence of file formats on different diagnostic tasks in dentistry. Eighteen studies, published between the years 1996 and 2022, were included. The following data were extracted from the selected articles: article title, authors' citation, publication date, country, diagnostic task, image file formats tested, compression level, and main conclusion. The most widely investigated diagnostic task was caries lesions (n = 10), led by root resorptions (n = 3), root fractures (n = 2), periapical lesions (n = 2), and periodontal disease (n = 1). The most commonly used radiographic techniques were periapical (n = 12) and bitewing (n = 6). The most frequently investigated image file formats were JPEG (all studies) and TIFF (n = 10 studies). BMP, PNG, and JPEG2000 were also included in 7, 3 and 3 studies, respectively. No studies included the DICOM file format. In regard to the subjective assessment of the several dental diagnostic tasks, the studies mostly showed that the influence of the file formats was not significant (n = 10/55.5%). As for the quality assessment of the included papers, more than 70% of the studies featured a low risk of bias. Current evidence on image file formats and dental radiographic diagnosis is reliable.

Composites were formulated with 60 wt.% of either PG6EMA or BisGMA (40 wt.% TEGDMA and 70 wt.% filler). DMPA (0.2 wt.%) and DPI-PF6 (0.4 wt.%) were added as photoinitiators, irradiated with a mercury arc lamp (320-500 nm, 500 mW/cm2; Acticure).

The composites were further characterized for water sorption/solubility, wet/dry flexural strength/modulus and polymerization stress. Data were analyzed with one-way ANOVA/Tukey's test (α = 0.05).
