Purpose: The aims of the present study were 1) to investigate the effects of local ethylenediaminetetraacetic acid (EDTA) chelation on alveolar bone healing after systemic administration of bisphosphonates; and 2) to compare the healing in alveolar defects created with ultrasonic and conventional surgery.
Materials And Methods: A total of 40 male Wistar rats were divided into 4 equal groups of 10 rats each (zoledronate and piezosurgery, zoledronate and bur, placebo and piezosurgery, and placebo and bur). The first 2 groups received weekly intraperitoneal injections of zoledronic acid (0.06 mg/kg), and the second 2 groups received saline solution for 4 weeks. After the last injections, horizontal defects 4 × 2 × 1 mm in size were created on the mandibular alveolar bone using piezosurgery or conventional bur surgery. The zoledronate groups received 10 minutes of local application of EDTA on 1 side and saline solution on the other side. In the placebo groups, only 1 side was treated (one half of the group with the bur and one half of the group with piezosurgery). All the rats were euthanized at 4 postoperative weeks for comparative histomorphometric evaluation of bone healing in the created defects.
Results: Bone formation was found to be the greatest in the placebo groups (P < .05). Although a greater amount of bone formation was observed with piezosurgery and EDTA among the bisphosphonate-treated groups, the difference between the zoledronate groups was not statistically significant (P > .05). Similarly, no statistically significant difference was found between the use of piezosurgery and conventional bur surgery within the placebo groups (P > .05).
Conclusions: The findings of the present study revealed improved bone healing with the use of piezosurgery and EDTA chelation, although the difference did not reach statistical significance. Further research should be performed to clearly identify the role of EDTA as a chelating agent and in prevention of medication-related osteonecrosis of the jaws development.

: Following tooth extraction, resveratrol (RSV) can support healing by reducing inflammation and microbial risks, though its poor solubility limits its effectiveness. This study aims to develop a solid nanocomposite by embedding RSV in lipid nanoparticles (mLNP) within a hydrophilic matrix, to the scope of improving local delivery and enhancing healing. Hydroxyapatite (HXA), often used as a bone substitute, was added to prevent post-extraction alveolus volume reduction.

The application of light-responsive nanomaterials (LRNs) in bone tissue engineering shows broad prospects, especially in promoting bone healing and regeneration. With a deeper understanding of the mechanisms of bone defects and healing disorders, LRNs are receiving increasing attention due to their non-invasive, controllable, and efficient properties. These materials can regulate cellular biological reactions and promote bone cell adhesion, proliferation, and differentiation by absorbing specific wavelengths of light and converting them into physical and chemical signals.

Opioids are a challenging class of drugs due to their dual role. They alleviate pain, but also pose a risk of dependency, or trigger constipation, particularly in cancer patients, who require the more potent painkillers in more advanced stages of the disease, closely linked to pain resulting from general inflammation, bone metastases, and primary or secondary tumour outgrowth-related nerve damage. Clinicians' vigilance considering treatment with opioids is necessary, bearing in mind extensive data accumulated over decades that have reported the contribution of opioids to immunosuppression, tumour progression, or impaired tissue regeneration, either following opioid use during surgical tumour resection and post-surgical pain treatment, or as a result of other diseases like diabetes, where chronic wounds healing constitutes a challenge.

: Totally endoscopic techniques have become increasingly popular in cardiac surgery, with minimally invasive mitral valve repair emerging as an effective alternative to median sternotomy. This approach could be particularly advantageous for patients with Noonan syndrome, who often present with structural thoracic anomalies and other comorbidities like bleeding disorders. Endoscopic mitral valve surgery is rapidly establishing itself as the new standard of care for mitral valve operations, demonstrating both safety and efficacy.
