While plaque‐induced gingivitis is one of the most common human inflammatory diseases,
several non–plaque‐induced gingival diseases are less common but often of major
significance for patients. The non–plaque‐induced gingival lesions are often manifestations
of systemic conditions, but they may also represent pathologic changes limited to gingival
tissues. A classification is proposed, based on the etiology of the lesions and includes:
Genetic/Developmental disorders; Specific infections; Inflammatory and immune conditions …
