Abstract Background This randomized study aimed at evaluating whether orthodontic tooth movement can induce detectable changes in gingival crevicular fluid (GCF) volume in patients with controlled periodontal disease. Methods Ten patients (8 women and 2 men, mean age of 46.2 ± 10.4 years) with controlled periodontal disease and flared incisors were included in the study. Gingival crevicular fluid samples were collected from the mid-palatal and mid-lingual sites of 1 central and 1 lateral incisor of each arch from each patient for a total of 4 individual samples per patient. These sites were selected to represent the pressure side of the applied forces (movement sites). Samples obtained from the arch without the appliance served as controls. Samples were collected at 1 week before orthodontic activation (–7d); right before the orthodontic appliance activation (0); after 1 and 24 hours; and after 7, 14, and 21 days of the activation. Filter paper strips were used in combination with a Periotron for GCF volume measurements. All patients received hygiene instructions and a kit containing toothbrush, fluoride dentifrice, and gluconate chlorhexidine 0.12% mouthwash to be used during all experiment. Results There were no statistically significant differences over time in the GCF volume for any samples from the two groups. When the two groups were compared, there were no statistically significant differences in the GCF volume at any time point. Conclusions The GCF volume could not be associated to orthodontic movement in teeth with controlled periodontal disease.
