Background: The crevicular fluid analysis represents a useful diagnosis tool, with the help of which noninvasive cellular metabolic activity can be analyzed. The aim of the study is to investigate comparatively IL1β and IL6 in the gingival crevicular fluid of clinically healthy adolescents and young adults during the acute phase of orthodontic treatment. Methods: Gingival crevicular fluid was collected from 20 patients (aged between 11 and 28) undergoing orthodontic treatment. Measurements were taken before (T0) and after 24 h after distalization forces were activated (T1). IL1β and IL 6 were analyzed using Elisa tests. The statistical tests used were two-sided t tests. Results: Between the two time periods there was a significant raise both in the crevicular fluid rate (0.57 µL at T0 vs. 0.95 µL at T1, p = 0.001) and in IL1β levels (15.67 pg/µL at T0 vs. 27.94 pg/µL at T1, p = 0.009). We were able to identify IL6 only in a third of the sites. There is a significantly increased level of ILβ at T1 in adolescents, more than in young adults (42.96 pg/µL vs. 17.93 pg/µL, p = 0.006). Conclusions: In the early stage of orthodontic treatment, the periodontal tissues of adolescents are more responsive to orthodontic forces than those of young adults.

Orthodontic mini-implants are well-known anchorage devices and stand out as a particularly effective tool for ensuring maximum anchorage without relying on patient compliance. Therefore, it is necessary to understand what levels of torque strains remain in the physiological limits and can guarantee the stability of these mini-implants. The aim of this study was to investigate and measure the initial and final torque values of orthodontic mini-implants when placed perpendicular to the maxillary and mandibular bone surfaces. In our study, orthodontic mini-implants from different companies were inserted perpendicularly using different insertion torques on the plate of both maxillary and mandibular bones from pig specimens. The torque values were then analyzed. The results of this study highlight the need for continued research to analyze the ideal insertion torque of different types of mini-implants depending on the insertion area, in order to achieve clinical success of mini-implants.

Essential oils (EOs) are complex plant-derived mixtures increasingly investigated for their anti-inflammatory, antioxidant, and vasoprotective properties. Thromboinflammation, a process integrating coagulation, platelet activation, endothelial dysfunction, and inflammatory signaling, plays a central role in vascular pathology; however, the contribution of EOs to this process remains insufficiently characterized. This narrative review aims to synthesize current molecular and experimental evidence regarding the effects of EOs and their major bioactive constituents on pathways converging toward thromboinflammation. A focused PubMed/MEDLINE search, supplemented by manual reference screening, was conducted to identify experimental and translational studies on EOs and selected constituents relevant to inflammatory mediators, oxidative stress, endothelial dysfunction, platelet activation, and thrombotic pathways. Available data from predominantly preclinical experimental models indicate that EOs can exert multi-target effects, including modulation of cytokine production, attenuation of oxidative stress, improvement in endothelial function, and inhibition of platelet aggregation, thereby influencing key components of thromboinflammatory pathways. Despite these promising findings, heterogeneity in chemical composition, limited standardization, uncertain exposure relevance, and the predominance of preclinical data remain important limitations. In conclusion, EOs represent a promising but still largely preclinical class of natural compounds capable of modulating interconnected mechanisms relevant to thromboinflammation; however, further translational and clinical studies are required to validate their therapeutic potential.

Background/Objectives: Sleep-disordered breathing (SDB), including obstructive sleep apnea, is common in children and is associated with mouth breathing, snoring, and neurobehavioral disturbances. In pediatric orthodontic patients, oral habits and craniofacial imbalances may contribute to airway dysfunction, making orthodontic evaluation a potential setting for early identification of SDB. This study aimed to estimate the prevalence of SDB and to evaluate its associations with parent-reported behavioral symptom profiles in a cohort of pediatric orthodontic patients. Methods: A multicenter cross-sectional study was conducted in 186 children aged 7–13 years attending orthodontic clinics in Oradea and Târgu Mureș, Romania. Parents completed a structured questionnaire on oral habits, the 22-item Pediatric Sleep Questionnaire (PSQ), with SDB defined as 8 or more positive responses, and a parent-reported behavioral screening form assessing ADHD symptom subtypes, oppositional-defiant disorder (ODD), conduct disorder, and anxiety/depression. These behavioral outcomes were based on screening measures and were not intended as clinical psychiatric diagnoses. Associations were analyzed using chi-square or Fisher’s exact tests, and multivariable logistic regression analyses were performed adjusting for age, sex, and weight status. Results: Mouth breathing was reported in 61.8% of participants, snoring in 26.9%, and SDB in 13.4%. Positive screens for ADHD-inattentive (p < 0.001), ADHD-hyperactive/impulsive (p < 0.001), ADHD-combined (p < 0.001), ODD (p < 0.001), and anxiety/depression (p < 0.001) were significantly more frequent among children with SDB. In multivariable analysis, SDB remained independently associated with ADHD-combined subtype (OR = 6.22), ADHD-hyperactive/impulsive symptoms (OR = 5.84), oppositional-defiant disorder (OR = 4.91), and anxiety/depression (OR = 4.38). Conclusions: SDB was identified in a meaningful proportion of pediatric orthodontic patients and was significantly associated with multiple screening-defined behavioral symptom domains. These findings support consideration of brief airway- and sleep-oriented screening during orthodontic assessment, particularly in school-aged children presenting with mouth breathing, snoring, or behavioral concerns. Given the cross-sectional and questionnaire-based design, the findings should be interpreted as associative and warrant confirmation in prospective studies using objective sleep measures.

Background/Objectives: Complex endodontic lesions characterized by significant periapical bone loss, diverse anatomical variations in the root canal system and apical resorption represent a major therapeutic challenge. Biodentine, a calcium silicate-based bioactive dental restorative material, has gained considerable attention because of its potential to promote and sustain the regeneration of bone tissue. This review aims to evaluate current evidence on Biodentine’s regenerative abilities in treatments of diverse endodontic pathology and highlight the clinical and radiographic outcomes. Material and Methods: A systematic review was conducted in accordance with PRISMA guidelines by searching for articles in three electronic databases: Medline (PubMed), Scopus, and Cochrane Library. Studies describing the application of Biodentine in cases of complex endodontic pathology with destruction of apical bone and apical resorption of roots were considered for inclusion in the study. Quality assessment was carried out using the Cochrane risk of bias assessment tool RoB 2.0. Results: The included clinical and radiographic studies demonstrated positive treatment outcomes after using Biodentine in difficult endodontic lesions, including a reduction in lesion size, improvement in symptoms and progression of periapical bone regeneration after 12 months of follow-up. No significant adverse outcomes were reported in the studies included. Conclusions: Biodentine proved to be an efficient biocompatible material in terms of managing complex endodontic lesions. Due to its bioactive properties and high efficiency as an apical plug, Biodentine is capable of inducing bone regeneration within the affected periapical area.

This study analyzed factors influencing the choice between Rapid Palatal Expansion (RPE), Miniscrew-Assisted RPE (MARPE), and Surgically Assisted RPE (SARPE) for treating maxillary transverse deficiency. Through a systematic review of literature from 2015-2025, key selection criteria were identified. The maturation stage of the midpalatal suture (Angelieri classification) was found to be the most critical factor, superseding chronological age, with non-surgical expansion becoming less predictable in advanced fusion stages (D and E). Additional factors include bone density, patient sex, and device positioning. The findings underscore the necessity for CBCT-based, personalized treatment protocols to ensure successful skeletal expansion, optimize clinical outcomes, and improve long-term stability.
