The aim of the study was to examine plaqueindex, gingivalindex and oral hygiene measure among patients between 20-26 years of age, who were treated at the Dental Hygienist Programme at the University of Kristianstad. The study was performed as a dental record. All 126 subjects with records in this age were including in the study. Sixteen records (13 %) were excluded because the criteria were not fulfilled. Plauqeindex, gingivalindex and oral hygiene measures were registered from 110 records. In 55 of 110 patients at least two plaqueindex were taken during the treatment period. The result shows that the value for gingivalindex was 24 % (range 0-89 %), the value for the first plaqueindex (PI 1) was 56 % (range 15-100 %) and the last plaqueindex (PI 2) in the treatment was 53 % (range 11-100 %). Eighty five percent had got some kind of oral hygiene instruction. The most usually oral hygiene measure was instruction by toothbrush (60 %). The least usually measure was instruction in toothpick (n = 1). The conclusion was that the patients had a high plaqueindex, both at the first and least occasion. The recommendations at own care were fairly low despite the high plaqueindex.
