Abstract

Background: Mechanical force of orthodontics causes changes in periodontal ligament vascularization and blood flow, resulting in biochemical and cellular changes as well as changes in the contour of the alveolar bone and in the thickness of the periodontal ligaments. Hyperbaric oxygen (HBO) therapy is one of many solutions stimulating the growth of new blood vessels and increasing tissue oxygenation. Thus, HBO plays a role in recovery of periodontal ligament and osteoblasts. Purpose: This study aimed to determine the effects of HBO therapy for seven days on periodontal ligament size and osteoblast number in the tension site during bone remodeling in tooth movement. Method: The study was true experimental laboratories with completely randomized control group post test only design. Twenty-four males guinea pigs were randomly divided into three groups. K0 was the control group without any treatment, K1 was the group given a mechanical orthodontic pressure, and K2 was the group treated with the addition of hyperbaric oxygen therapy. The maxillary incisors were moved distally by elastic separator. After HBO therapy on day 7, all of the groups were sacrificed, and then periodontal ligament size and osteoblast number were analyzed by one-way Anova and LSD statistical tests. Result: The results showed significant differences in the size of the periodontal ligament and the number of osteoblasts in the tension site among the groups (p<0.05). Conclusion: HBO therapy at 2.4 ATA for 7 days is effective in recovery of periodontal ligament and increased osteoblast number during bone remodeling in tension area of orthodontic tooth movement.

Abstract

Introduction: Large, full-thickness upper eyelid defects management presents a thorough and challenging approach due to the multilaminar character of the eyelid and its dynamic function. The Cutler-Beard flap method has been the mainstay management, but posterior lamellar graft usage with recent modifications may reduce complications. Case Presentation: A 43-year-old man presented to the emergency ward after a traffic accident left him with a full-thickness laceration on his left upper eyelid and an approximately 60% avulsion on the one-third medial of the eyelid. Traumatic ptosis was also found. After considering the large size of the affected area and the probability of faster wound healing, a free graft from the tarsus and conjunctival eyelid of his fellow eye was harvested to replace the posterior lamellar of the affected eye and closed the defect with a rotational skin flap from the remaining of the left upper eyelid. Conclusions: This technique could be one of the alternatives to the more common cutler-beard flap with mild complications. However, temporary visual obstruction cannot be avoided due to the traumatic ptosis complication of this patient.
