Abstract
Background
Dentists frequently conduct tooth extractions when there is damage to the tooth or the tissue that supports it. When a tooth is extracted, the alveolar bone will sustain injury. Most of the initial bone volume is lost following the healing phase after extraction. Rehabilitation must start as soon as a tooth is missing, mainly because the alveolar bone is severely damaged during the tooth extraction, particularly in the buccal region where the tooth is removed. Dental implant is one method of replacing lost teeth. One of the most important elements influencing the clinical result of dental implants is a change in the dimension of the alveolar bone. Several bone-grafting techniques, such as socket preservation techniques, have been developed to increase the volume of bone throughout the healing phase after tooth extraction. This study aims to assess the impact rhBMP-2 on creating bone regeneration through VEGF and HIF-1α in the mandibular socket post-extraction in Wistar rats.
Method
On the anterior side of the mandible, in the socket area where the tooth was extracted, rhBMP-2 was injected into the socket, and the xenograft material was applied with a syringe. Male, 9-week-old Wistar rats were chosen (n = 30).
Result
Our statistical evaluations have revealed a significantly higher VEGF-A and HIF-1α expression post-extraction of the rhBMP-2 and xenograft group compared to other group treatments. These findings are significant as they provide a deeper understanding of the mechanisms involved in bone regeneration post-extraction.
Conclusion
Our study suggests that injecting rhBMP-2 into the grafted material and socket extraction during GBR dramatically increases the expression of VEGF-A and HIF-1α. These findings have the potential to significantly impact oral surgery and regenerative dentistry, opening up new possibilities for enhancing bone regeneration techniques.
期刊介绍:
Journal of Oral Biology and Craniofacial Research (JOBCR)is the official journal of the Craniofacial Research Foundation (CRF). The journal aims to provide a common platform for both clinical and translational research and to promote interdisciplinary sciences in craniofacial region. JOBCR publishes content that includes diseases, injuries and defects in the head, neck, face, jaws and the hard and soft tissues of the mouth and jaws and face region; diagnosis and medical management of diseases specific to the orofacial tissues and of oral manifestations of systemic diseases; studies on identifying populations at risk of oral disease or in need of specific care, and comparing regional, environmental, social, and access similarities and differences in dental care between populations; diseases of the mouth and related structures like salivary glands, temporomandibular joints, facial muscles and perioral skin; biomedical engineering, tissue engineering and stem cells. The journal publishes reviews, commentaries, peer-reviewed original research articles, short communication, and case reports.
