A common causal factor for periodontal cyst formation is chronic inflammation. Periodontal cysts, particularly those related to the periodontal ligament, often arise in response to longstanding inflammation in the periodontal tissues. Chronic inflammation is typically a result of periodontal disease processes, where the presence of bacteria and inflammatory mediators lead to a localized area of tissue destruction and the possible formation of a cyst.

Cysts develop as a way for the body to contain or isolate the inflammation and tissue breakdown, which can subsequently become a fluid-filled sac. Consequently, the relationship between chronic inflammation and cyst formation is significant in the context of periodontal health, indicating how the body's response to persistent pathological conditions can result in the development of cysts.

While poor oral hygiene can lead to periodontal disease and thus contribute indirectly to cyst formation, it is the chronic inflammation associated with these conditions that directly correlates with the formation of cysts. Trauma to the tooth might lead to other complications but is not a primary factor in cyst formation specific to periodontal conditions. Lastly, dental caries, while a significant dental concern, deal more with decay of the tooth structure and less with the inflammatory processes seen in periodontal conditions leading to cysts.
