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: 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.

Background and Objectives: Preheated composite resins have been proposed as an alternative to conventional luting agents due to their improved resistance, color stability, and adaptation. This review aims to critically evaluate the current literature on the use of preheated composites as luting agents exclusively on dentin and enamel, focusing on their mechanical behavior, optical properties, and biological effects, in order to determine whether they provide superior clinical outcomes compared with conventional resin cements. Materials and Methods: A comprehensive literature search from 2015 to 2025 was conducted in accordance with PRISMA-ScR guidelines. Eligible studies included in vitro investigations comparing the preheated composite with other luting agents performed on human, bovine, analog dentin or enamel substrates. Studies meeting these criteria were screened, evaluated, and synthesized. Results: Fifteen studies met the inclusion criteria: nine focused on the mechanical performance, and the remaining six studies examined additional properties such as color stability, pulpal temperature changes during preheating, film thickness characteristics, and the influence on marginal discrepancy. Conclusions: Preheated composite resins offer improved mechanical properties, marginal adaptation, and fracture resistance compared with conventional luting agents. However, their performance is highly technique-sensitive, and clinical outcomes depend on operator skill, restoration thickness, and material selection. Preheating generally does not compromise color stability, but it can elevate pulpal temperature, particularly when residual dentin is thin. Overall, preheated composites have potential clinical advantages, provided that careful handling and appropriate application are ensured.
