Gingiva of the oral mucosa provides a practical source to isolate fibroblasts for therapeutic purposes because the tissue is easily accessible, tissue discards are common during routine clinical procedures and wound healing after biopsy is fast and results in complete wound regeneration with very little morbidity or scarring. In addition, gingival fibroblasts have unique traits, including neural crest origin, distinct gene expression and synthetic properties and potent immunomodulatory functions. These characteristics may provide advantages for certain therapeutic approaches over other more commonly used cells, including skin fibroblasts, both in intraoral and extra-oral sites. However, identity and phenotype of gingival fibroblasts, like other fibroblasts, are still not completely understood. Gingival fibroblasts are phenotypically heterogeneous, and these…fibroblast subpopulations may play different roles in tissue maintenance, regeneration and pathologies. The purpose of this review is to summarize what is currently known about gingival fibroblasts, their distinct potential for tissue regeneration and their potential therapeutic uses in the future.

Objective: This in vitro study aimed to analyze the effects of ionizing radiation on immortalized human osteoblast-like cells (SaOS-2) and further assess their cellular response in co-culture with fibroblasts. These analyses, conducted in both monoculture and co-culture, are based on two theoretical models of osteoradionecrosis - the theory of hypoxia and cellular necrosis and the theory of the radiation-induced fibroatrophic process.
Design: SaOS-2 cells were exposed to ionizing radiation and evaluated for cell viability, nitric oxide (NO) production, cellular morphology, wound healing, and gene expression related to the PI3K-AKT-mTOR pathway.

Background: Successful periodontal regeneration depends on primary wound closure and interdental papilla preservation. In this case study, we introduce a novel triangle papilla access approach (T-PAA) performed under a surgical microscope for treating interdental bone defects. In this novel approach, buccal incisions were used to access root surfaces and bone defects, avoiding interdental papilla incisions and preventing papillary collapse and necrosis.

Objective: Titanium surface modifications improve osseointegration in dental and orthopedic implants. However, soft tissue cells can also reach the implant surface in immediate loading protocols. While previous research focused on osteogenic cells, the early response of soft tissue cells still needs to be better understood.

Alveolar bone defects caused by inflammation or trauma jeopardize patients' oral functions. Guided bone regeneration (GBR) is widely used in repairing periodontal tissue, with barrier membranes play a crucial role in preserving the bone regeneration space. In this study, an injectable dual-crosslinked hydrogel was developed to improve the existing barrier membranes in flexibility and functionality.

Peri-implantitis associated with dental implants shares characteristics with destructive periodontal diseases. Both conditions are multifactorial and strongly correlated with the presence of microorganisms surrounding the prostheses or natural dentition. This study aimed to evaluate the antimicrobial activity and toxicity of a mucoadhesive hydrogel functionalized with aminochalcone (HAM-15) against Aggregatibacter actinomycetemcomitans, Fusobacterium periodonticum, Prevotella intermedia, Porphyromonas gingivalis, Tannerella forsythia, and Candida albicans.
