Periodontal Diseases

The grounding supports a multifactorial aetiology in which dysbiotic oral microbial communities initiate local inflammation. It also indicates that inherited and acquired abnormalities in host response contribute to disease development and progression, rather than a single cause.

Periodontal disease involves an interaction between dysbiotic microbiota and an aberrant host immune response in gingival and periodontal tissues. Cytokine networks are implicated in recruiting immune cells, controlling pathobionts, and driving osteoclastic activity and alveolar bone loss, with sustained inflammation creating a feedback loop that promotes further tissue destruction.

Supported risk factors include pathogenic plaque biofilm, higher biofilm load or altered biofilm composition, smoking, carbohydrate intake, and socio-economic factors. The grounding also notes inherited susceptibility, including genetic variants, and broader lifestyle, behavioural, and systemic disease-related influences.

The grounding supports management at the level of prevention and control, diagnosis, therapy, drug therapy, and diet therapy, but it does not specify particular regimens. At a modality level, treatment is described broadly as periodontal therapy aimed at controlling pathogenic plaque biofilm and inflammation, with adjunctive preventive and dietary measures.
