简要总结

Background: Free gingival graft (FGG) is used to increase keratinized tissue dimensions. This prospective clinical trial was conducted aiming to determine whether the addition of an autologous platelet-rich fibrin (PRF) would improve soft tissue healing of donor sites and decrease pain scores.

Methods: Twenty four patients were planned to receive FGG to augment keratinized tissue dimensions in the mandibular incisors area. Donor sites were assigned randomly to receive PRF or not by a flip of a coin during the screening visit. Patients were instructed to complete a pain study form. The palatal donor area were evaluated for complete wound healing records. These data were assessed and recorded before surgery, and 1,2,3,4 and 8 weeks postoperatively.

详细描述

Background: Despite a relatively painful surgical procedure, free gingival graft (FGG) is still commonly used to increase keratinized tissue dimensions. This prospective clinical trial was conducted aiming to determine whether the addition of an autologous platelet-rich fibrin (PRF) after harvesting a FGG would improve soft tissue healing of donor sites and subsequently decrease pain scores.

Methods: Twenty four patients were planned to receive FGG to augment keratinized tissue dimensions in the mandibular incisors area. Enrolled patients received periodontal examination, oral hygiene instructions and full-mouth debridement followed by standardized FGG of similar dimensions. Donor sites were assigned randomly to receive PRF or not by a flip of a coin during the screening visit. Patients were instructed to complete a pain study form to analyze pain scores including VAS, NRS-101, VRS-4 as well as three anxiety scales at base line. The palatal donor area were evaluated for complete wound healing based on the degree of color match, tissue texture, and contour of the surgical area compared to preoperative records. These data were assessed and recorded before surgery, and 1,2,3,4 and 8 weeks postoperatively.

入选标准

  • lack of keratinized tissue in the mandibular central incisor region

排除标准

  • uncontrolled systemic disease that might contraindicate periodontal surgery
  • severe gag reflex preventing maxillary surgical procedure
  • inability or unwillingness to provide informed consent

结局指标

主要结局

Changes in Visual Analog scale (VAS)

时间窗: 1, 2, 3, 4 and 8 weeks

a visual analog scale (VAS) consisting a 10-cm line with two extremes at either end. "no pain" and "pain that could not be more severe". Patients were asked to mark a point on the line that represent their level of perceived pain

次要结局

  • Changes in degree of color match(1, 2, 3, 4 and 8 weeks)
  • Changes in contour of the surgical area(1, 2, 3, 4 and 8 weeks)
  • Changes in tissue texture(1, 2, 3, 4 and 8 weeks)
