The objective of this work was to compare the stress pattern generated on the root by a computer-aided design and computer-aided manufacturing (CAD-CAM) milled fiberglass post under occlusal load in a photoelastic simulation and to compare its flexural strength (FS) to other types of posts. A total of 15 simulated roots, produced from photoelastic resins, were created using human canine teeth. These specimens were then separated into three distinct groups: Fiber post conventional, which consisted of fiberglass posts; fiber post customizable, which involved prefabricated fiberglass posts anatomized with composite resin; and fiber post CAD-CAM, which utilized CAD-CAM milled fiberglass posts. Following the application of Relyx ARC cement, the posts underwent photoelastic testing using a polariscope and FS testing using a universal testing machine. The data were submitted to analysis of variance (ANOVA) and Tukey's test at 5% significance level. It was found that the stress was significantly greater (<i>p</i> < 0.05) for the customizable post (246.5 MPa ± 218.7) in comparison to both the conventional (135.8 MPa ± 99.3) and CAD-CAM (136.5 MPa ± 68.4) posts; the latter group exhibited the lowest flexural values (50.8 MPa ± 7.9), which were significantly different from both the conventional group (123.0 MPa ± 26.9) and the customized group (230.3 MPa ± 18.9), which also differed from each other.

Obesity is associated with various health complications, including detrimental effects on oral health. Despite the significant implications of obesity on dental health, there is limited research specifically examining this relationship in rural populations. <b>Objective:</b> This study aimed to explore the relationship between obesity type and the need for dental prostheses in adults from the rural population of Yucatán,Mexico, in order to highlight the influence that obesity may have on oral health. <b>Methodology:</b> An observational, descriptive, cross-sectional study was conducted in July 2021, with a final sample of 114 participants aged between 15 and 81 years. Subjects classified as obese according to the body mass index (BMI) criteria were included, specifically those with a BMI ≥ 30. All participants were evaluated by a single experienced dentist, using a standardized methodology to collect data regarding their oral health, clinical history, and health habits. <b>Results:</b> A notable absence of dental prostheses was observed in over 80% (92 participants) of the subjects. A direct correlation was identified between obesity type and the need for prostheses, with a higher prevalence of prosthetic need in individuals with a higher BMI, where 75% of the obese (38 out of 50 obese participants) reported needing dental prostheses. This suggested a significant interplay between oral health, obesity, and dietary choices. <b>Conclusions:</b> The findings of this study emphasized the importance of optimal oral health to facilitate chewing and digestion, highlighting that obesity, as a condition, can negatively influence oral health. Further studies are needed to investigate the necessity for preventive measures and treatment, as well as to promote awareness of oral health within the community.</p>","PeriodicalId":13947,"journal":{"name":"International Journal of Dentistry","volume":"2025 ","pages":"9485502"},"PeriodicalIF":1.9,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11996272/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144012095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
