Background/Objectives: Dental anxiety has been demonstrated to exert a significant influence on the frequency of treatment, the degree of patient compliance, and the long-term implications for oral health. The objective of this study was to evaluate the extent of dental anxiety experienced by patients attending an oral surgery practice in Germany. In addition, the study sought to assess their preventive dental behaviour and to explore any potential associations between anxiety levels and the utilisation of preventive care services. Methods: The present study comprised 102 consecutive adult outpatients from a private oral surgery practice. The assessment of dental anxiety was conducted using the Corah’s Dental Anxiety Scale (DAS). The behaviour of the subjects in relation to preventative dental care was measured using a series of six standardised items, including the frequency of tooth brushing, tartar removal, and professional tooth cleaning. The data analysis comprised descriptive statistics, chi-square (χ²) tests, multiple linear regression, and one-way analysis of variance (ANOVA). Results: The mean DAS score was 12.69 (SD = 3.36). According to the DAS classification system, 28.4% of patients reported low anxiety, 50.0% moderate anxiety, and 21.6% high dental anxiety. Regression analysis explained 10% of the variance in DAS scores (R² = 0.128, adj. R² = 0.100). The analysis revealed that age (β = −0.218, p = 0.035) and lower educational level (β = −0.357, p < 0.001) were associated with higher anxiety scores, whereas sex was not a significant predictor. Preventive dental behaviour, encompassing practices such as tooth brushing, professional tooth cleaning, and tartar removal, did not exhibit significant disparities across anxiety groups (all p > 0.05). Conclusions: While dental anxiety was prevalent among the patient sample, it did not exert a significant influence on preventive dental behaviours. However, patients with lower levels of education and younger age exhibited higher dental anxiety scores. These findings underscore the necessity for targeted educational and preventive strategies in patients with elevated dental anxiety.

Acrylic resin is widely used in removable dental prostheses due to its biocompatibility, low cost, and ease of handling; however, it presents mechanical limitations and a high susceptibility to microbial colonization, particularly by Candida albicans. The incorporation of nanoparticles into polymethyl methacrylate (PMMA) has been investigated as a strategy to mitigate these drawbacks. This scoping review evaluated the impacts of incorporating chitosan (CTS) nanoparticles into PMMA on antimicrobial activity and mechanical properties. A comprehensive search of the PubMed, Scopus, Web of Science, and BVS databases resulted in the retrieval of 1912 records. After removing 557 duplicates and applying the eligibility criteria, 9 in vitro studies were included. Despite methodological heterogeneity, most studies reported enhanced antifungal activity against C. albicans and improvements in mechanical properties, such as microhardness and overall strength, when CTS was incorporated. Thus, CTS appears to be a promising additive for denture base resins, with the potential to reduce denture-associated infections and increase the longevity of prostheses. Nevertheless, standardized methodologies and well-designed in vivo and clinical investigations remain essential to determine optimal concentrations, incorporation techniques, and long-term clinical performance before implementation. A scoping review design was selected due to the exploratory nature of the study and the heterogeneity of available evidence, which precludes direct comparisons and quantitative synthesis.

This study aimed to explore the added value and usage of laser Doppler flowmetry (LDF) in conjunction with continuous tissue (arterial) oxygen saturation (SO₂) monitoring, electrical pulp testing (EPT), cold stimulation (CS) testing, and apical X-rays (RX). LDF data were evaluated in relation to three different scenarios. LDF records of all four upper incisors from 30 randomly selected patients aged 21–40 were analysed in relation to the following scenarios: (a) simultaneous SO₂ measurements using a pre-manufactured splint handled by an experienced LDF dentist, (b) EPT, and (c) CS. A total of 120 teeth were analysed, of which 11 were non-vital (7 denervated and 4 traumatised). Data assessment showed the following mean LDF values: vital teeth: 23.6 Perfusion Units (PU), SD 6.3 and SaO₂ of 88.7%, SD 17.1. For non-vital teeth, the mean LDF value was 16.1 PU (SD 11.8) and the mean SO₂ value was 70.8% (SD 31.9). The standard deviation was found to be twice as high for non-vital teeth as for vital teeth. No direct relationship was found between LDF and SO₂ values at low SO₂. For vitality discrimination, the ROC curves showed an area under the curve of 0.799 for LDF and 0.643 for SO₂. EPT data assessment showed a mean value of 18.1 (SD 19.7) out of a possible score of 0–80. This was distributed as follows: seven non-vital teeth (80/80); 109 vital teeth; and four undecided teeth. This was compared to the LDF and SO₂ results. The data assessment showed nine non-vital teeth, 108 vital teeth, and three undecided teeth in comparison to LDF and SO₂ results. Conclusion: LDF and SO₂ do not complement each other sufficiently in detecting non-vital teeth when the selection criteria are applied. While LDF clearly contributes, the vital or non-vital classification still depends on a combination of X-ray, sensitivity, and vitality tests.
