The objective of the study was to determine the effect of platelet-rich fibrin (PRF) on the healing of soft tissues of socket after atraumatic exodontia. The present is a single-blind, cross-sectional randomized controlled trial. It was carried out in the Dental Service of the Santa Isabel District Hospital of Porvenir – Peru, during the years 2016 and 2017. The sample consisted of 51 patients whose alveoli post exodontia were randomly divided into 2 groups, each patient signed an informed consent. Group A (control) was left with a blood clot for normal healing and group B (experimental) was given PRF (as a plug and membrane), obtained according to the Choukroun protocol. The effect of PRF on the healing of the soft tissues of the alveoli after atraumatic exodontia was used the Landry index. The measurements were made at 7 and 14 days after surgery. For the comparison of each one of the variables of the study, the Mc Nemar test and the Fisher exact test were used. The statistical significance was 5 %. When comparing both groups in the healing of the soft tissues of alveoli after atraumatic exodontia, a statistically significant difference was found at 7 and 14 days after surgery (p <0.05). When comparing both groups in the healing of soft tissues of alveoli after atraumatic exodontia according to age group and sex, it was found that there is no statistically significant difference at 7 and 14 days after surgery (p> 0.05). The PRF has a positive effect on the healing of the soft tissues of the alveoli after atraumatic exodontia independently of sex and age.
KEY WORDS: platelet-rich fibrin, PRF, socket extraction, wound healing, soft tissues.
