The effect of hyperbaric oxygen on two different methods of rapid canine distraction

Abstract

Objectives:Objectives: Objectives: Objectives: To evaluate the possible increase in bone formation using hyberbaric oxygen and to detect the possible root resorption in rapid canine distraction. Methods:Methods: Methods: Methods: Sixteen healthy patients Indicated for orthodontic treatment with extraction of at least the maxillary first premolars were selected. They were divided into two groups; a hyperbaric group (HBO) and a control group (NHBO). Split mouth technique was implemented where one side was randomly selected to encounter periodontal ligament distraction (PDLD) while the other side received dentoalveolar distraction (DAD). The PDLD and DAD surgries were carried out after the extraction of the maxillary first premolars. The distractors were cemented in their places and are left for one week latency period. The HBO group started their hyperbaric oxygen sessions for 20 days; where 90 minutes of complete oxygen inhalation at 2.5 atmosphere absolute (ATA) were received in every section serum bone alkaline phosphatase (B-ALP) samples and standardized periapical Xray were taken from the subjects before the surgery. The distractors were activated. The screw moved 1mm/day. B-ALP samples and periapical X-rays were collected from the subjects when the canines were fully retracted Results:Results: Results: Results: The serum bone alkaline phosphatase of HBO group was significantly elevated. The average degree of tipping in the PDLD side of both 1-Post graduate student, groups was significantly higher than that of the DAD side. The DAD preserves more bodily movement in comparison to PDLD. The hyperbaric oxygen aids of attaining more bodily movement during the distraction of the canines. No root resorption incidence was detected during the short time of distraction.
