Background And Aim: To determine the effect of pre-cooling injection site on pain perception in patients attending a dental camp at lifeline express, Habibganj.
Methods: A split mouth interventional study assessed the effect of pre cooling the injection site in patients (n=33) requiring bilateral buccal infiltration prior to extraction. One side of the patient's mouth received the intervention after the injection site was pre cooled with ice for 3 minutes along with topical Lidocaine, while the other mouth side of the same patient received only topical Lidocaine and served as control group. A structured proforma assessed the demographic characteristics and risk factors that influence pain perception in patients. Mann-Whitney U tests and Wicoxon rank sum test were used for statistical analysis. Statistical significance was defined at P<0.05.
Results: The results revealed a significant difference in pain perception between control and intervention group as assessed using both Heft-Parker Visual Analog Scale (median score 3.0 and 1.0) and Sound Eye Motor scale (median score=1.0 and 0.0) (P<0.01). For both the scales the assessed and self reported variables Gender, Location, Chief Complaint, Region and Arch were found to be statistically significant.
Conclusion: Pre cooling injection site reduced pain perception in patients.

Effectiveness of Lidocaine with Epinephrine Irrigation in Reducing Acute Pain from Surgical Removal of Mesioangular-Impacted Third Molars.

Background: Anesthetic irrigation is an effective treatment for postoperative pain suppression in patients after molar extraction, but exerts a short period of extraction. The study aimed to evaluate the effect of lidocaine with epinephrine irrigation on acute pain relief in healthy volunteers with inferior alveolar nerve block (IANB) injection for the surgical removal of mesioangular (MA)-impacted third molars.
Methods: A total of 28 patients (56 samples) with bilateral MA-impacted third molars were recruited.

Objectives: This study is to assess how 22 kHz and 50 kHz spontaneous ultrasound vocalization (USV) calls would be affected by different origins of pain so as to validate the use of USV in pain studies.
Methods: Five well-established rat models of pain were used to evaluate various parameters of spontaneous 22 kHz and 50 kHz calls in adult male rats in terms of both acute and chronic or inflammatory and neuropathic or somatic and visceral origins. The effects of local lidocaine blockade of the injection site and intraperitoneal administration of antidepressant (amitriptyline) and anticonvulsant (gabapentin) were examined as well in typical inflammatory and neuropathic pain models, respectively.
The second phase of tumor invasion driven by immune cells: A study on doxorubicin-loaded PLG nanoparticles.
J Control Release

D. Mendeleev University of Chemical Technology of Russia, Miusskaya pl. 9, 125047, Moscow, Russia. Electronic address:
Poly(lactide-co-glycolide) (PLG) nanoparticles loaded with doxorubicin have reached phase-I clinical trials for treating advanced solid tumors. This study explores cell hitchhiking, where nanoparticles associate with blood cells and investigates the impact on pharmacokinetics and tumor migration. Previous findings highlighted the early post-injection phase dominated by nonspecific nanoparticle-cell interactions and burst release.

Introduction: Alveolar bone defects pose significant challenges in dentistry. Due to the complexity of alveolar bone anatomy and insufficient repair mechanisms, large bone defects are difficult for the body to heal naturally. Clinical treatment typically involves the use of bone substitute materials.
