A clinical study on the influence of suturing material on oral wound healing.

Background/aim: Suture materials play an important role in healing, enabling reconstruction and reassembly of tissue separated by the surgical procedure or trauma, and at the same time facilitating and promoting healing and hemostasis. Suture materials are used daily in oral surgery, and are considered to be substances most commonly implanted in human body. The aim of this clinical study was to examine the speed of wound healing and complications incidence, after the use of three different absorbable synthetic suture materials in oral surgery (catgut, Dexon and Vicryl rapide), and to ascertain which one is the most suitable for oral surgery.

Influence of suturing material on wound healing - An experimental study on dogs.

Background/aim: The most common materials implanted in the human organism are suture materials that are classified on the basis of several criteria, usually the origin, structure, and properties. The properties of suture materials are related to its absorbability and non-absorbability. When using resorbable materials it is of great importance to determine whether its absorbability and tensile strength help wound healing in function of time.

Production of IL-10 and IL-12 by antigen-presenting cells in periapical lesions.

Background: Interferon-γ (IFN-γ) plays an important role in the pathogenesis of periapical lesions. Its expression is up-regulated by interleukin (IL)-12) and down-regulated by IL-10. The aim of this work was to study the cellular source of these cytokines and their mutual interactions in human periapical lesions.

Production of proinflammatory and immunoregulatory cytokines by inflammatory cells from periapical lesions in culture.

Background: The role of cytokines in pathogenesis of periapical lesions is not well understood. The aim of this study was to study the correlation between proinflammatory and immunoregulatory cytokines in periapical lesions and their relationship with cellular composition and clinical presentation.

Methods: Inflammatory cells were isolated from 67 human periapical lesions and cultivated for 24 h.

Proinflammatory and immunoregulatory mechanisms in periapical lesions.

Proinflammatory and immunoregulatory cytokines are important for the pathogenesis of periapical lesions. However, little is known about how their functions are balanced and controlled at different phases of lesion development. The aim of this study was to examine the relationship between the production of Th1, Th2, Th17 and T regulatory cell (T reg) cytokines by human periapical lesion mononuclear cells (PL-MNC) in culture and their correlation with cellular composition and clinical presentation of the lesions.

Interleukin-17 plays a role in exacerbation of inflammation within chronic periapical lesions.

Interleukin (IL)-17 plays an important role in inflammation and certain autoimmune diseases. However, its role in the pathogenesis of chronic dental periapical lesions has not been studied. Periapical lesion mononuclear cells (PL-MNC) were isolated from inflammatory cells and phenotypically analyzed by immunocytochemistry.

[Nasopalatine duct cyst].

Background: Nasopalatine duct cyst is a developmental, nonodontogenic cyst of jaw.

Case Report: We presented a 46-year-old male with nasopalatine duct cyst. The clinical examination revealed fluctuant swellings of the anterior palate, without pain, 4-5 cm in diametar.
