Peripheral giant cell granuloma associated with dental prostheses: A case report

Table 1 Local factors relevant to peripheral giant cell granuloma

Category	Examples	Clinical relevance
Biofilm-related factors	Plaque, calculus, food impaction	Sustain chronic gingival inflammation
Prosthetic/restorative factors	Overhanging margins, poor marginal adaptation, rough surfaces, defective pontic design, poor emergence profile	Increase plaque retention and/or soft tissue trauma
Periodontal factors	Chronic periodontitis, deep inflammation around abutment teeth	May contribute to a reactive gingival environment
Traumatic factors	Repetitive mechanical irritation, impinging prosthetic components	Promote persistent local injury
Systemic/contextual contributors	Hormonal changes, xerostomia, impaired hygiene access	May increase susceptibility, though usually not sufficient alone
