Abstract
Objective
This study aimed to enhance conventional glass ionomer cement (GIC) by incorporating 15 % chitosan, 5 % bovine serum albumin (BSA), 0.05 % tricalcium phosphate (TCP), and 1 μg translationally controlled tumor protein (TCTP), resulting in an enhanced-GIC formulation. The study evaluated its adhesion properties, biocompatibility, and ability to promote pulp tissue healing in rabbit anterior teeth.
Materials and methods
The enhanced-GIC was tested in a rabbit model to assess its physical adhesion and biological effects on pulp tissue. Following cavity preparation and material placement, the teeth were observed for 21 days. Histological evaluations focused on inflammation, toxicity, and collagen synthesis in pulp tissue.
Result
The enhanced-GIC showed comparable adhesion properties to conventional GIC. Histological analysis revealed no significant inflammation or toxicity in the pulp tissue of either group. The enhanced-GIC group exhibited superior biocompatibility, demonstrated by increased lymphocyte infiltration and enhanced collagen synthesis within the pulp tissue, suggesting its potential for promoting tissue regeneration.
Conclusion
The enhanced-GIC formulation shows promise as a sublining material in restorative dentistry, offering benefits in pulp tissue healing and collagen formation, while maintaining adhesion comparable to conventional GIC. This study highlights enhanced-GIC's potential for use in dental restorative procedures, particularly for cases requiring pulp regeneration.
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.
