The aim of the work is to characterize the dental and hygienic status of the oral cavity in middle-aged patients residing in the area with natural iodine deficiency, depending on the severity of iodine deficiency disorders. In 193 patients aged 35-44 years who applied for dental care, the level of ioduria, thyroid volume, plasma level of thyroid stimulating hormone (TSH) and free thyroxine, as well as the indices, such as DEF (decayed, extracted, filled teeth), PMA (papillary marginal attachment), CPI (community periodontal index), and OHI-S (simplified oral hygiene index) reflecting the patient dental status, have been assessed. High prevalence of iodine deficiency (59.5%) has been noted among patients requiring prosthodontic treatment, 14.1% of them had severe iodine deficiency with the ioduria median of 75.5 μg/L. The ioduria severity is correlated with the thyrotropin and free thyroxine level in the blood plasma. Uncompensated iodine deficiency negatively affects the prevalence and intensity of dental caries, the condition of oral mucosa and periodontal tissues, and the hygienic status of the oral cavity. High and average values of Spearman's rank correlation coefficient have been found for the levels of dental indices, ioduria and blood plasma thyroid hormones in the adult population residing in iodine-deficient area.
