Smoking and Oral Health: Epithelial-stromal interactions in salivary glands of rats exposed to chronic passive smoking.
Cigarette smoke leads to precancerous and cancerous lesions in the mouth even when the exposure is passive. The salivary glands are amongst the tissues exposed to the smoke but it is unclear whether or not passive cigarette exposure is related to detectable changes in these tissues.
The objective of this study was to observe the tissue architecture of the parotid and submandibular glands in rats after passive cigarette exposure and to measure any changes that occurred.
Conclusion: Passive smoking led to substantial structural changes in the salivary glands which could significantly affect function. (Source: Archives of Oral Biology)
