Health of the oral cavity of 18-years old students in vocational schools without dental care.

63 18-year-old students of both sexes of vocational school of gastronomic profile were examined. The state of hard tissues of teeth was assessed on the basis of the DMF number, that of periodontium according to the CPI index and the hygiene of the oral cavity - using the simplified OHI index of Greene and Vermillion. The thickness of the dental plaque was estimated on the basis of its colour, using Red-Coty tablets produced by Butler. A group of 14 students specializing in production of cakes was isolated as an increased risk group. In the studied group of students a 100 percent frequency of dental carries was found. The average DMF value for all students was 11.6 and average D = 5.5; for the group of increased risk the DMF value was 12.8 and D = 8.0. For 80.7 percent of the examined students the hygiene of the oral cavity was good (OHI index - code 1); the state of the periodontium was as follows: 62 percent of students had dental scale (CPI index - code 2) and the occurrence of gingival bleeding was found for 38 percent of the students (CPI index - code 1).
