Objective: To clinically assess socket healing after tooth extraction and the occurrence of intra- and postoperative complications in patients with chronic kidney failure (CKF) receiving hemodialysis (HD) by comparing them with a control group.
Study design: This prospective study involved 48 patients with CKF receiving HD (study group [SG]) and 29 participants without CKF (control group [CG]) undergoing tooth extractions. No prophylactic antibiotic was administered to the participants. One calibrated dentist evaluated all individuals at 3, 7, 21, and 60 days after the tooth extractions and assessed hemostasis time, occurrence of local or distant infection, epithelialization, and deposition of alveolar bone.
Results: In the SG, 87 teeth were extracted through 65 interventions, and in the CG, 76 teeth were extracted through 36 interventions. Bleeding beyond 30 minutes was observed in 12 interventions (18.5%) in SG participants and was controlled with local hemostatic agents. Neither group had individuals presenting with postoperative infectious complications at the surgical site or at a distance. After 21 days, we observed delayed epithelialization in 29.9% (26 of 87) of the individuals in the SG compared with 3.9% (3 of 37) of those in the CG (P < .001). After 60 days, all the sockets were epithelialized and showing radiographic signs of alveolar bone neoformation.
Conclusions: Individuals with CKF receiving hemodialysis tend to heal well after dental extractions. They did not have an increased risk of infectious complications after simple tooth extractions, but they showed prolonged bleeding events more often than control subjects. Additional research studies using larger sample sizes of patients with CKF receiving hemodialysis are needed to confirm our findings.
