Background: There is no consensus regarding the prophylactic removal of mandibular third molars (TM) in fracture lines to facilitate healing. Recent evidence suggests that poor healing is attributed to the limited use of antimicrobials, delayed care and semi-rigid fixation as a treatment method, favoring retention of TM.
Study Design: A retrospective cohort study of all patients presenting with mandibular angle fractures at the Hippokration General Hospital of Athens (2006-2011) was designed to examine the association between the presence versus absence of TMs in the line of mandibular fractures and the fracture healing process. Development of complications during the healing process was the outcome of interest. Additional factors considered were patient age, sex, and fracture etiology.
Materials And Methods: Data were extracted from a retrospective chart review, including information from clinical and radiological examinations. The analytical sample included 112 patients with 121 angle fractures. Bivariate methods including Fisher's exact and chi-square tests were used to test the association between TM presence in the fracture line and healing complications.
Conclusion: This study found no association between the presence of mandibular TM in the fracture line and postoperative complications and the healing process when combined with light intermaxillary fixation for 15 days.

Chronic wounds are notoriously challenging to heal as they are often halted in their normal healing process. The concept of TIME (Tissue, Inflammation/Infection, Moisture imbalance, Epithelial edge advancement) has been widely utilized in clinical practice to prepare wound beds and promote healing, particularly in longstanding wounds. Traditional methods of wound bed preparation are often inadequate in healing chronic wounds or they may not be tolerated by patients.

The complexation of nucleic acids and collagen forms a platform biomaterial greater than the sum of its parts. This union of biomacromolecules merges the extracellular matrix functionality of collagen with the designable bioactivity of nucleic acids, enabling advances in regenerative medicine, tissue engineering, gene delivery, and targeted therapy. This review traces the historical foundations and critical applications of DNA-collagen complexes and highlights their capabilities, demonstrating them as biocompatible, bioactive, and tunable platform materials.

A diabetic wound (DW) is an alteration in the highly orchestrated physiological sequence of wound healing especially, the inflammatory phase. These alterations result in the generation of oxidative stress and inflammation at the injury site. This further leads to the impairment in the angiogenesis, extracellular matrix, collagen deposition, and re-epithelialization.

Tissue regeneration after a wound occurs through three main overlapping and interrelated stages namely inflammatory, proliferative, and remodelling phases, respectively. The inflammatory phase is key for successful tissue reconstruction and triggers the proliferative phase. The macrophages in the non-healing wounds remain in the inflammatory loop, but their phenotypes can be changed interactions with nanofibre-based scaffolds mimicking the organisation of the native structural support of healthy tissues.
