SANCHEZ GONZALEZ, Linda N; BARCELO SANTANA, Federico H; JIMENEZ CASTILLO, René  and  BENAVIDES RIOS, Alejandro. Accelerated physical deterioration of in vitro ocular prostheses. Rev. Odont. Mex [online]. 2012, vol.16, n.1, pp.14-17. ISSN 1870-199X.

Ocular prosthesis is a facial prosthesis mode destined to alloplastically repair partial or total loss of the ocular globe as well as its several malformations. It is well established that the best prosthetic rehabilitation has been obtained with acrylic resin ocular prosthesis. The aim of this study was to determine aqueous absorption and solubility, as well as accelerated physical deterioration degree such as change of color of characterized and non characterized ocular prostheses. Thirty eye shapers were manufactured following the flasking and characterizing UNAM technique. Aqueous sorption, solubility and accelerated deterioration tests were carried out. Turkey test and ANOVA analysis were applied to the results and a frequency graph was as well performed. Non characterized samples were reported as having greater sorption. Characterized samples were reported as having greater solubility; greater color changes were observed in the clear surface.

Keywords : Ocular prosthesis; aqueous absorption; solubility; accelerated deterioration.
