(1) Background: Currently, more and more studies reveal the fact that the use of ozonated oil in dentistry brings visible benefits. The aim of this study was to evaluate the efficacy of ozonated olive oil by evaluating daily index changes (2) Methods: The available products were used in this study: ozonized olive oil (Ozon Relive) and organic cold-pressed extra virgin olive oil. At the start of the study, all mouthwashes are placed in the same type of containers and labeled with numbers from 1 to 20. The recommended dose is one teaspoon of oil, about 6 mL per day. (3) Results: Ozonated oil (Group 1) and olive oil (Group 2) groups showed statistically significant differences to oral indices (p < 0.001 in both). (4) Conclusions: The results suggested that ozonized olive oil can be fully included among the products able to assist in controlling the causative factors of gingivitis while reducing its clinical manifestations.

Introduction: The physiological process of wound healing is a complex and dynamic series of events that aims to restore damaged tissues to their original structure and function. Platelet-rich plasma (PRP), an autologous blood-derived product, is characterized by a high concentration of platelets suspended in a small volume of plasma, along with a complete array of coagulation factors at physiological concentrations. Beyond platelets, PRP contains a significant quantity of bioactive growth factors, such as platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), and transforming growth factor-beta (TGF-β), all of which are crucial mediators of tissue repair and osteogenesis. Due to these properties, PRP has garnered considerable attention in oral surgery, where the efficient regeneration of both hard and soft tissues is critical for the optimal therapeutic outcomes. Objectives: This systematic review aimed to critically evaluate the efficacy of PRP in oral surgical procedures, with particular emphasis on its role in the regeneration of both soft and hard tissues, as well as its clinical outcomes. Furthermore, the review sought to identify the diverse surgical applications of PRP and assess the impact of its use in conjunction with grafting materials on regenerative outcomes. Methods: A comprehensive systematic review was conducted, analyzing articles published within the last decade regarding the application of PRP in oral surgery, specifically focusing on periodontal, regenerative, and implant-related procedures. Studies were selected based on rigorous inclusion criteria, assessing the utilization of PRP across different clinical settings. Results: Thirteen relevant studies were included, which were categorized as follows: three studies involving implant surgery, three studies focusing on third molar extractions, two studies on regenerative surgery, two studies addressing periodontal surgery, one study examining intrabony periodontal defects, and two studies on ridge augmentation procedures. The majority of studies reported modest improvements in clinical parameters such as periodontal probing depth and clinical attachment level (CAL). Furthermore, significant positive outcomes were observed in soft tissue healing, with notable enhancements in bone density. These results suggest that PRP may facilitate the healing process, particularly in soft tissues, while also promoting bone regeneration to a degree. Conclusions: The findings of this systematic review underscore the potential of PRP as a valuable adjunct in oral surgery, demonstrating significant benefits in the regeneration of soft tissues and, to a lesser extent, hard tissues. Notably, the standalone application of PRP did not yield substantial improvements in regenerative outcomes. However, when PRP was used in combination with grafting materials, more pronounced benefits were observed, indicating a synergistic effect that enhances both soft and hard tissue regeneration. These findings support the rationale for incorporating PRP into clinical practice, particularly in conjunction with grafting materials, to optimize patient outcomes in oral surgery. Further research, particularly involving larger sample sizes and long-term follow-ups, is necessary to fully elucidate the optimal clinical applications and mechanistic pathways of PRP in oral regenerative procedures.

Objectives: This article introduces a digital technique for virtual articulator mounting by employing the scan of a facebow worn by the patient as a virtual reference. Methods: The digital technique enables the transfer of the maxillary arch orientation relative to the cranial base into a CAD-CAM environment (Ceramill Mind; AmannGirrbach), without the need for ionizing radiation or identification of facial landmarks. By digitally aligning the intraoral scans of the dental arches (Trios 4; 3Shape) with a 3D facial scan and the scanned facebow in position (Artex; AmannGirrbach), clinicians can reproduce the cranium-to-maxilla spatial relationship accurately and intuitively. Results: This radiation-free protocol provides virtual cross-mounting and allows for the use of a semi-adjustable articulator within common CAD-CAM software. Conclusions: Given that intraoral scanners, facial scanners, and design software with articulator simulation are becoming more available in modern clinical workflows, this method introduced here could be a viable radiation-free and easy-to-use alternative. However, larger cohorts and standardized testing protocols are needed to determine its clinical reproducibility and reliability.

Background and Objectives: College life is a time when students take more responsibility for health-related behaviors. Aim: To determine the oral health behaviors of dental students, to motivate their transformation into cyanogenic behaviors by applying the planned behavior model, and to determine the degree to which students can modify behavior for oral health. Material and Methods: The results of the initial and final assessment (4 months apart) of the bacterial plaque present by means of the Quigley Hein and API indexes were collected from the student files. The Health-Promoting Lifestyle Profile II -HPLP II and Generalized Self-Efficacy Scale (GSE) questionnaires were used to determine the variables with predictor values that influence the cognitive-perceptual factors. Results: For the “health responsibility” domain, the average total value was 2.53 ± 0.9 (SD). For the “interpersonal relationships” domain, the average value was 2.82 ± 0.79. In the case of the “nutrition” domain, the desire to change the behavior of the participants was moderate (2.53 ± 1.19). “Physical activity” represents an important field in the everyday life of young adults. The results of the study indicated a moderate desire for change (2.52 ± 0.97). In the case of “spiritual growth”, in which self-esteem, the way the individual perceives the environment and the adaptation to it were evaluated, a great desire for change was observed (2.74 ± 0.82). Scale GSE questionnaire showed an α coefficient of 28.52 ± 0.82, a value that indicated a moderate to a high level of efficacy and self-confidence. Conclusions: The results of the study showed that students have a moderate tendency to change in all areas, except for interpersonal relationships, where the desire to change something is increased. The participants have a moderate to a high level of self-efficacy and self-confidence.

(1) Background: Dental implant instability represents a dynamic biomechanical process influenced by functional loading, peri-implant bone stiffness, and systemic conditions affecting bone metabolism. In patients with systemic bone disorders, altered material properties and impaired remodeling may reduce effective implant–bone interface stiffness, potentially increasing micromotion beyond what is detectable by conventional clinical indicators. The aim of this study was to develop and evaluate a predictive bioengineering model of implant instability based on Periotest-derived dynamic measurements. (2) Methods: A retrospective analysis was performed on 79 dental implants placed in patients with and without systemic bone disorders. Implant micromotion was quantified using Periotest values (PTVs). Linear and logistic regression analyses were applied to model the relationship between systemic bone status, implant location, and biomechanical instability (defined as PTV > +2.0). A load–stiffness–micromotion framework was used to provide mechanical interpretation of the findings. (3) Results: Implants placed in patients with systemic bone disorders exhibited significantly higher Periotest values compared to controls (+2.1 ± 1.3 vs. −0.4 ± 1.1; mean difference 2.5 PTV units, 95% CI 1.97–3.04; p < 0.001). High-risk biomechanical instability (PTV > +2.0) was observed in 46% of implants in the systemic group compared to 9% in controls. Multivariable logistic regression demonstrated that systemic bone disorders were independently associated with a 2.6-fold increase in the odds of high-risk instability after adjustment for implant location. The observed instability pattern was consistent with reduced effective peri-implant stiffness in systemically compromised bone. (4) Conclusions: Dental implant instability in systemically compromised patients can be interpreted as a load–stiffness imbalance at the implant–bone interface. The proposed predictive bioengineering framework links dynamic Periotest measurements with mechanical modeling and systemic bone status, enabling quantitative risk stratification beyond static stability assessments.
