Application of Oleozon in the Treatment of Subprosthesis Stomatitis L. Lemus, E. Ordaz, E. Rodríguez. Briones Montoto Dental Clinic, Pinar del Rio, Cuba. The aim of this study is to evaluate the efficacy of OLEOZON (ozonized sunflower oil) in the treatment of Subprosthesis Stomatitis. 122 patient suffering from this disease were treated on "Briones Montoto" Dental Clinic (Pinar del Rio province) between January to April of 1996. Patients were divided in 3 groups: group 1, 50 patients treated with OLEOZON, without their prosthetics device; group 2, 45 patients without their prosthesis and without OLEOZON treatment and group 3, 27 patients who maintained their prosthesis and received OLEOZON, independently of the stomatitis degree affection. The influence of different factors: age, sex and stomatitis degree affection was statistically analyzed, through contingency tables. The healing was total (100 %) in the first group and the time required was reduced from 43.1 (group 2) to 8.4 days, not detecting any adverse reactions. 89 % and 4 % of healing was obtained in group 2 and 3, respectively. It is concluded that the withdrawal of the prosthesis is a very important aspect to consider and that with OLEOZON applications the healing time is reduced significantly.
