[Incidence of parodontal diseases in workers of the Chełm Cement Plant exposed to cement dust].

The purpose of the study was evaluation of the incidence of parodontal diseases in workers exposed in their occupation to cement dust. Stomatological examinations were carried out in 127 workers of the plant (98 men and 29 women) aged 18 to 64 years. The control group comprised 117 persons (58 men and 59 women) aged 22 to 66 years. The condition of the parodontium was assessed and classified according to a 3-grade scoring system used for parodontal disease assessment. The obtained data were subjected to statistical and lysis.
