Effect of topical ozonetherapy on gingival wound healing in pigs: histological and immuno-histochemical analysis

Abstract In this study, the effects of ozonetherapy on secondary wound healing were evaluated histologically and immuno-histochemically. Material and Methods: 8 healthy pigs were used in this study. Six wounds with 10 mm in diameter were created through the punch technique on the palatinal gingiva of each pig. Ozone gas was applied on only 3 wounds (test group) and the remaining 3 were left to natural healing (control group). Biopsy samples were taken from one of the wounds in each group on the third day, from another wound of each group on the seventh day, and from another one on the tenth da...
