Knowledge about the influence of fillers in denture base resin is vague. This systematic review aimed to report the reinforcing effect of fillers on the mechanical properties of denture base resin by following PRISMA guidelines. Two electronic databases (Pubmed/Medline & Web of Science) were searched for articles using the keywords: fibers in denture base, fillers in denture base, and reinforcement of denture base. Laboratory studies complying with the inclusion criteria were reviewed according to the set protocol. The established focus question was: “Do reinforcing fillers positively influence the mechanical properties of polymethyl methacrylate (PMMA) heat polymerized denture base material?” A total of twenty-nine relevant papers qualified for final inclusion. Of these, 24 were determined to have a moderate risk of bias. Micron or nano-sized metal/metal oxides particles and glass fibers were the frequently used reinforcing agents. The trend of evaluating fractural strength (FS) was common. Most of the studies limited the use of reinforcing agents up to 5 wt.%. FS, fracture toughness (FT), and impact strength (IS) tend to increase if the fillers are chemically bonded and well-dispersed in denture base resin. Though fillers with a higher elastic modulus increase the hardness of the reinforced denture base resin, they compromise other mechanical properties. Well-dispersed lower filler loading PMMA denture base resin can enhance the FS, FT, and other related mechanical properties.

Halitosis is a growing concern for patients seeking dental treatment. Women experience hormonal changes throughout different phases of their life. These changes may affect volatile organic compound (VOC) production and can be linked to halitosis. The aim of this study was to evaluate the effect of hormonal changes on self-perceived halitosis in a sample of females using a self-administered questionnaire. This study used a cross-sectional observational design. The questionnaire was distributed electronically through Google forms. A total of 1089 participants completed the questionnaire. Almost 50% of participants were below the age of 25; and 12% were of menopausal age (defined as 45 years and older). Most participants reported having regular menstrual cycles (63.5%) while only 20% reported having hormonal disturbances. Almost 62% of the sample reported that they notice halitosis on themselves with 27.6% indicating their perception of halitosis occurred at different times of the month. Around 12% of the sample thought that a relationship between halitosis and their menstrual cycle existed with 4.6% reporting halitosis during menstruation. The present study found that regularity of menstrual cycle and hormonal disturbances can affect females’ self-perceived halitosis and the prevalence of oral health symptoms.

Introduction: This study evaluates the impact of oral health issues on critical areas of daily functioning, including job performance, psychological well-being, self-rated oral health, and dietary habits.Methods: Utilizing NHANES data, the analysis applies Pearson correlation, multiple regression, and data visualization techniques (scatter plots, heatmaps, and box plots) to quantify associations between oral health variables, such as mouth aching (OHQ620), food avoidance (OHQ660), job difficulty due to mouth issues (OHQ640), and embarrassment (OHQ680).Results: Strong correlations were found between mouth aching and job difficulty due to mouth issues, with a Pearson correlation coefficient of 0.99, and between difficulty eating (OHQ670) and job difficulty due to mouth issues, with a coefficient of 0.98. Psychological impacts were also notable; feeling bad about one's mouth (OHQ630) had a high correlation with embarrassment (0.99), while mouth aching had a weaker association (0.88). Self-rated oral health (OHQ845) showed a negative correlation with both mouth aching (−0.83) and feeling bad about one's mouth (−0.83), indicating decreased self-assessment of oral health as symptoms increase. Multiple regression revealed that difficulty eating had a substantial positive coefficient (1.19) for food avoidance, while mouth aching had a minor negative effect (−0.13). Smoking exposure was positively associated with oral health issues, particularly with mouth aching and embarrassment.Conclusions: The findings highlight significant impacts of oral health issues on job performance, psychological well-being, and lifestyle, suggesting the need for integrated oral healthcare strategies that address both physical discomfort and emotional consequences.Practical implications: Enhanced oral health interventions focusing on symptom management and psychological support could reduce nutrition barriers, improve occupational functioning, and increase quality of life.

As of November 2023, twenty-four states, two territories, and DC have legalized marijuana for non-medical use, leading to concerns about its potential oral health effects. This study investigated the association between marijuana use and clinical dental outcomes among adults in the US. We analyzed data from the National Health and Nutrition Examination Survey (NHANES) from 2015 to 2018 using a cross-sectional survey of non-institutionalized US civilians. Marijuana use was assessed among 18–59-year-old adults and categorized as never, former, or current frequent use. The dental outcomes included the prevalence of untreated coronal caries, root caries, and missing teeth. We employed logistic and negative binomial regressions to assess the crude and adjusted associations between marijuana use, dental caries, and tooth loss. Of the 6,424 participants, 13.85% of US adults aged 18–59 years were current frequent marijuana users (21.67 million), with the highest prevalence among 18–29-year-olds (21.31%), males (17.54%), and non-Hispanic Black individuals (21.31%). Frequent marijuana users showed the highest prevalence of untreated coronal caries (33.4%). Before adjusting for socioeconomic confounders, current frequent marijuana users had 1.76 times higher odds of having teeth with coronal caries, whereas former frequent users had 1.47 times higher odds. However, the associations between marijuana use and all dental outcomes were attenuated after adjusting for socioeconomic confounders, tobacco use, and access to dental care. Although marijuana use was associated with worse dental health, socioeconomic factors, tobacco use, and access to dental care were more significant contributors to the prevalence of untreated dental caries and missing teeth than marijuana use alone.
