Gingival hyperpigmentation is a major esthetic concern for many people, although it not medical problem, people complain of dark gums as unesthetic. depigmentation periodontal plastic surgical procedure that removes or reduces hyperpigmented gingiva. Various methods like scalpel, free gingival autografts, electrosurgery, cryosurgery, and abrasion with diamond bur scalpels, bur, various types la...

OBJECTIVE To evaluate the effects of freezing, thawing, and autograft of a hemi-ovary on steroid secretion, endometrial maturation, and ovarian histology in ewes. DESIGN Experimental animal study. SETTING Laboratoire de Zootechnie, Ecole Nationale Vétérinaire, Marcy l'Etoile, France. ANIMAL(S) Six lambs aged 6 months to 1 year old. INTERVENTION(S) Hemi-ovaries were prepared and frozen f...

Extensive nerve injuries often leading to nerve gaps can benefit, besides the gold standard represented by autologous nerve grafts, by the inciting field of tissue engineering. To enhance the role of biomaterials in nerve regeneration, the nerve conduits are associated with Schwann or Schwann-like cells. In this study, we evaluated rat sciatic nerve regeneration, by using a biodegradable nerve ...

BACKGROUND Long-gap peripheral nerve defects arising from tumor, trauma, or birth-related injuries requiring nerve reconstruction are currently treated using nerve autografts and nerve allografts. Autografts are associated with limited supply and donor-site morbidity. Allografts require administration of transient immunosuppressants, which has substantial associated risks. To overcome these lim...

OBJECTIVE To review short term results of uncemented cup implantation and the fate of bulk femoral head autografts in patients with acetabular bone deficiency due to dysplasia of the hip. We used bone scintigraphy to assess the viability of the grafts. METHODS We treated 19 hip joints of 17 patients with osteoarthritis due to developmental dysplasia of the hip with uncemented total hip arthro...
