The aim of the study was to determine the prevalence of periodontal disease and the treatment needs in a population of 214 factory workers in Romania. Of those examined, 9.34 per cent were in periodontal health (code 0), 21.49 per cent had gingival bleeding (code 1), 18.69 per cent had supra- or subgingival calculus (code 2), 32.71 per cent presented with pathological pockets 4-5 mm deep (code 3) and 17.76 per cent had pathological pockets 6 mm or deeper (code 4). The distribution of these subjects among the treatment need categories revealed that 30.83 per cent would need improvement in personal oral hygiene (I), 51.40 per cent from the subjects would need treatment (I) + scaling (II) and 17.76 per cent would need treatment (I + II) + complex treatment (III).
