Background: In dental practice, different situations require etching the enamel layer. Acid etching, the present golden standard, may be replaced by other methods, such as laser etching. The main focus of our scoping review is to assess the existent literature regarding the effectiveness of different types of lasers, to identify the main aspects studied so far, and to understand where new search strategies are needed. Methods: The search was conducted in several databases focusing on the laser etching of human definitive enamel. We included English language articles published between January 2000 and December 2021. Results: The 34 articles reviewed showed that hard lasers, Er:YAG, Er,Cr:YAG, may represent an alternative etching method on enamel surfaces. They create a fractured, irregular surface and open dentin tubules, highly suitable for adhesion but with a lower risk of cavity formation. Nd:YAG, CO₂, and Diode lasers do not help in creating sufficient shear bond strength. There is, however, evidence suggesting that microcracks in the enamel layer may appear after thermomechanical ablation using laser energy. Conclusions: While the use of acid etching is still successfully used for enamel conditioning, some researchers have emphasized the role played by saliva in the enamel-remineralization process a few days after the procedure. In this context, laser energy can be used, especially for bonding ceramic brackets in the case of orthodontic treatments. However, as thermomechanical ablation can generate microcracks, further research is required in order to establish clear findings concerning the use of laser energy on enamel etching.

Background and Objectives: Menopause is a natural physiological process involving hormone production changes, affecting many functions and systems. This scoping review offers a contemporary outlook on oral issues related to menopause, such as saliva production, periodontal and alveolar bone issues, and changes in the microbiome, and it also investigates the effects of hormonal therapy. Materials and Methods: A literature search from 2019 to 2024 was conducted according to PRISMA-ScR guidelines. Articles investigating the oral effects of menopause were included. Results: A total of 30 studies were covered; 8 focused on salivary alterations, 5 on periodontal issues, 7 on bone, 3 on the microbiome, and 7 on multiple oral problems, showing that xerostomia and altered taste are the most common oral manifestations, followed by indirect causal effects on periodontitis. Many of these alterations can be contained through regular consultations and adequate hygiene. Some alveolar bone changes may occur after menopause and are associated with osteoporosis. Conclusions: Postmenopausal women experience notable reductions in salivary flow, pH levels, and taste sensitivity, which are associated with hormonal fluctuations as well as factors such as age, medication use, and treatments for climacteric symptoms. This population is at increased risk for periodontitis, tooth loss, altered taste, lichen planus, candidiasis, and decreased bone mineral density, which also affect the peri-implant area. Osteoporosis and hormonal changes can play a significant role in causing these increased risks. Maintaining proper oral hygiene and consistently monitoring bone health are essential. While changes in the oral microbiome are more heavily influenced by reductions in salivary flow than by menopause itself, hormone therapy may help improve periodontal health by reducing harmful bacteria and fostering a more balanced microbial environment. The intricate impact of hormones on oral health highlights the necessity for further research.

Background/Objectives: Air particle abrasion (APA) is a common surface preparation method in dentistry, particularly for improving bond strength to dentin. This review evaluates the influence of APA on dentin adhesion. Methods: A systematic literature search from 2018 to 2023 was conducted according to PRISMA-ScR guidelines. Articles investigating the effects of APA on dentin adhesion using different particle types, sizes and adhesive systems were included. Data extraction included particle size, air pressure, outcomes tested and failure modes. Results: Fourteen primary studies met the criteria. Bioactive glass showed higher bond strength and more cohesive failures than alumina. Alumina particles (50 μm) bonded effectively in etch-and-rinse adhesive systems but failed more often in self-etch systems. Silica-modified alumina and mixed abrasive systems showed improvements in bonding performance. Optimal APA parameters were identified as 50 μm particle size, 60 psi (4 bar) air pressure and 5 s exposure time. Longer exposure times provided no additional benefit. Self-etch systems showed reduced bond strength compared to etch-and-rinse systems. Conclusions: This review looks at how particle type, size and air pressure affect dentin adhesion. Bioactive glass is a superior material due to its bond strength and reduced cytotoxicity. The optimal APA parameters are 50 μm particle size, 60 psi and 5 s. Etch-and-rinse systems are recommended for optimal adhesion. Further research is required on APA protocols and long-term durability.

Background: Burnout syndrome represents a significant challenge in healthcare, impacting dental professionals globally across all geographic, demographic, or socioeconomic backgrounds. Pervasive work-related stress and insufficient management practices highlight the urgent need for enhanced awareness and targeted interventions. Objectives: This systematic review aimed to evaluate the prevalence, causes, and impacts of burnout among dental professionals and to explore the effectiveness of various occupational health interventions aimed at managing and preventing burnout in the dental sector during different phases of the COVID-19 pandemic. Methods: We conducted a systematic review following the PRISMA guidelines, searching electronic databases, including PubMed, Scopus, and Web of Science, from January 2014 to April 2024. The eligibility criteria included studies reporting on the prevalence of burnout, interventions to reduce burnout, and the impact of burnout on dental practices. A quality assessment was performed using the Newcastle–Ottawa Scale for observational studies. Results: The findings indicate high levels of emotional exhaustion, depersonalization, and reduced personal accomplishment among dental practitioners, with significant variations influenced by workplace factors, professional relationships, and pandemic-related stresses. Differential effects based on educational level and age were also evident. Conclusions: This review highlights the urgent need for targeted public health initiatives and occupational health strategies to address and mitigate burnout in dentistry. Emphasizing professional relationships and workplace dynamics could play a crucial role in the prevention and management of burnout (PROSPERO registration no. CRD42024586616).

Background: Miniscrew-assisted rapid palatal expansion (MARPE) has gained attention as an effective alternative to traditional rapid palatal expansion, particularly in adult patients. This scoping review synthesizes recent evidence to assess the clinical efficacy and safety of MARPE, addressing a gap in comprehensive, up-to-date analyses in this area. Objective: To present the recent assessments concerning MARPE influencing factors, side effects, soft tissue alterations, and airway changes, focusing on comparisons with conventional devices. Methods: Using PRISMA guidelines, we conducted a search of the literature published in 2018–2023 using Medline, Scopus, and Embase databases. This review focused on randomized controlled trials, cohort studies, and other reviews that evaluated the outcomes of MARPE. Results: Our analysis included 75 studies and revealed that MARPE significantly improves suture expansion with fewer dental and skeletal side effects compared to traditional methods. The technique shows high efficacy in subjects up to 25 years of age, with reduced incidence of complications and improved stability of expansion. Conclusions: The results support MARPE as a viable and superior alternative for maxillary expansion in late adolescents and adults. Given its advantages over traditional methods, MARPE should be considered a standard procedure in orthodontic treatment plans. Future research should focus on long-term outcomes and optimization of patient-specific treatment protocols.

Brackets are metallic dental devices that are very often associated with acidic soft drinks such as cola and energy drinks. Acid erosion may affect the bonding between brackets and the enamel surface. The purpose of this study was to investigate the characteristics of brackets’ adhesion, in the presence of two different commercially available drinks. Sixty human teeth were divided into six groups and bonded with either resin-modified glass ionomer (RMGIC) or resin composite (CR). A shared bond test (SBS) was evaluated by comparing two control groups with four other categories, in which teeth were immersed in either Coca-Cola^TM or Red Bull^TM energy drink. The debonding between the bracket and enamel was evaluated by SEM. The morphological aspect correlated with SBS results showed the best results for the samples exposed to artificial saliva. The best adhesion resistance to the acid erosion environment was observed in the group of teeth immersed in Red Bull^TM and with brackets bonded with RMGIC. The debonded structures were also exposed to Coca-Cola^TM and Red Bull^TM to assess, by atomic force microscopy investigation (AFM), the erosive effect on the enamel surface after debonding and after polishing restoration. The results showed a significant increase in surface roughness due to acid erosion. Polishing restoration of the enamel surface significantly reduced the surface roughness that resulted after debonding, and inhibited acid erosion. The roughness values obtained from polished samples after exposure to Coca-Cola^TM and Red Bull^TM were significantly lower in that case than for the debonded structures. Statistical results evaluating roughness showed that Red Bull^TM has a more erosive effect than Coca-Cola™. This result is supported by the large contact surface that resulted after debonding. In conclusion, the prolonged exposure of the brackets to acidic drinks affected the bonding strength due to erosion propagation into both the enamel–adhesive interface and the bonding layer. The best resistance to acid erosion was obtained by RMGIC.
