The objective of this work was to compare the micro-tensile bond strength (µTBS) of CAD/CAM (Computer-Aided Design/ Computer-Aided Manufacturing) specimens cemented with different pairing of adhesives and resin-cements using two Immediate Dentin Dealing (IDS) approaches in comparison with Delay Dentin Sealing (DDS). Coronal dentin from 108 molars were divided into nine groups (n = 12) depending on the adhesive/resin-cement (A-C) assigned. Lava™ Ultimate (4 × 10 × 10 mm) was cemented according to different strategies: IDS1(cementation after dentin sealing), DDS (dentin sealing and cementation at 2-weeks), IDS2 (immediate dentin sealing and cementation at 2-weeks). Samples were sectioned and tested until failure to determine the µTBS. Failure mode was categorized as dentin/cement (DC), at Lava™ Ultimate/cement (LC) and hybrid (H). Kruskal–Wallis and Mann–Whitney U tests and influence of the type of failure on the µTBS by survival analysis with competing risk was explored. Mostly, µTBS values were equal or higher in IDS2 than DDS. In general, A-Cs that showed higher µTBS, have high percentages of LC failure. Survival analysis with competing risk between DC + H and LC values showed that some A-Cs would significantly increase the µTBS values for IDS2. A-Cs with the highest adhesion values showed a high percentage of fractures at the LC interface, suggesting that the adhesion at the adhesive/dentin interface would be higher.

The worldwide pandemic has exposed healthcare professionals to a high risk of infection, exacerbating the situation of uncertainty caused by COVID-19. The objective of this review was to evaluate the psychological impact of the COVID-19 pandemic on dental professionals and their patients. A literature review was conducted using Medline-Pubmed, Web of Science, and Scopus databases, excluding systematic reviews, narratives, meta-analyses, case reports, book chapters, short communications, and congress papers. A modified version of the Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the selected studies. The search retrieved 3879 articles, and 123 of these were selected for the review (7 longitudinal and 116 cross-sectional studies). Elevated anxiety levels were observed in dental professionals, especially in younger and female professionals. Except for orthodontic treatments, patients reported a high level of fear that reduced their demand for dentist treatment to emergency cases alone. The results suggest that the COVID-19 pandemic has had psychological and emotional consequences for dental professionals and their patients. Further research is necessary to evaluate the persistence of this problem over time.

To quantify the discolouration of the temporary acetal resins in vivo, based on the weeks of follow-up and the salivary pH in the three thirds of the tooth. To find out if the final CIELAB coordinates can be predicted from the initial colour coordinates, the salivary pH, the situation (in thirds) and the weeks of follow-up. Colour coordinates (L, C, and h) were recorded by spectrophotometry in 13 participants fitted with hybrid provisional complete dentures made of acetal resin. Colour recordings were made on the day of placement and after several weeks of follow-up (6 to 31 weeks). Salivary pH was also measured as a predictor variable for colour change. The ANOVA statistical test and regression models have been used. The highest colour difference according to ∆Eab* was 27.46 units after 15 weeks of follow-up and the lowest was 7.34 units after 17 weeks of follow-up. Neither in the cervical nor in the middle third any regressor variable (initial L*, initial C*, initial h*, salivary pH and weeks of follow-up) was able to significantly predict any of the final colour coordinates (p > 0.05). The colour change of the temporary acetal resins used exceeds the threshold of clinical acceptability, and it is not acceptable to maintain satisfactory aesthetics. The weeks of follow-up and the salivary pH are not capable of satisfactorily predicting the final color coordinates of the acetal resins.

Background: Rheumatoid arthritis and periodontitis are chronic inflammatory diseases linked to systemic complications, including increased cardiovascular risk. The impact of glycemia, lipid profile and atherogenic cardiovascular risk indices in patients with rheumatoid arthritis (RA) and periodontitis, compared to controls, has not yet been evaluated. We aimed to analyze whether periodontitis acts as an aggravating factor in this relationship. Methods: In a case–control study, we assessed biochemical, RA-related markers and four atherogenic indices (Atherogenic Index of Plasma, Castelli Risk Index I, Castelli Risk Index II, and Triglyceride–Glucose Index). Periodontitis was evaluated using a gingival inflammation index (BOP) and a periodontal severity index (PIRIM). Multiple linear regression models were used to analyze whether periodontitis had a differential effect in RA cases versus controls. Results: A total of 46 participants were included (32 RA cases, 14 controls). Periodontitis was more prevalent among cases (62.5% vs. 28.5%). BOP was significantly higher in RA patients (p < 0.001) and associated with LDLC (p = 0.031). Both BOP and PIRIM correlated with higher CRI-1 and CRI-2 values across groups. PIRIM was also linked to increased LDLC (p = 0.018) and decreased HDLC (p = 0.003). Conclusions: RA and periodontitis appear to interact synergistically and are associated with a more atherogenic profile. These findings highlight periodontal health as a potentially modifiable factor in reducing cardiovascular risk in RA patients.

Asbestos in all its forms is a Group 1 material agent with proven carcinogenic effects in the human being since 1977. Exposure to asbestos can be considered unsafe. The use of asbestos in the field of dentistry had a common use in the manufacture of dental prostheses in the 1960s and 1970s. Taking into account the long induction period of this agent and the plausibility for being a risk factor in dentistry, the objective of this study is to propose a plan for the prevention of occupational risks due to asbestos exposure in dentistry by means of the contribution of a panel of experts. An Expert Panel (EP) approach was used in which a group of nine experts identified and documented the use of asbestos in the dental profession. EP was created and followed the protocol in accordance with the EuropeAid Assessment Guidelines. As a result of this study, EP documented the common use and sources of asbestos in dentistry in prosthetic materials, dental dressings, and in the coating of casting cylinders. EP also created a consensus document on the priority measures for the Plan for the Prevention of Risks from Asbestos in Dentistry, based on previous reports from the European Commission Senior Labour Inspectors’ Committee. The document concluded that obtainment of information, receiving specific training on the subject and performing epidemiological studies, and the proper risk assessments were the priority measures to adopt.

Population aging increases the demand for home-based dental care, but access remains limited for older adults who are homebound. Although teledentistry is a strategy for overcoming mobility barriers, its feasibility within the routine of Primary Health Care (PHC) requires further investigation. This pragmatic pilot trial evaluated a teledentistry protocol for monitoring homebound older adults. Six homebound older adults in the Brazilian PHC system were assigned to receive either weekly remote monitoring via a telehealth platform or conventional home visits over a three-week period. Feasibility was assessed using the Acceptability, Adequacy, and Feasibility measures of the intervention (scale 1 to 5), along with diagnostic instruments (OFI-8, OHIP-14, Kihon Checklist). Teledentistry demonstrated moderate adequacy (3.5) and feasibility (3.3). However, acceptability was lower (3.0) due to severe digital literacy barriers that required caregiver mediation. Remote data collection proved technically stable, and the OFI-8 effectively tracked functional decline. In contrast, the intervention group showed a worsening of OHIP-14 scores, reflecting a likely increase in awareness of unmet needs without immediate physical relief. In conclusion, although continuous remote monitoring is technically feasible and safe, the low digital literacy of the target population suggests that a hybrid model—combining teledentistry with targeted in-person visits—appears to be more equitable.
