Statement of problem: Previous research indicates that oral hygiene of adolescents is often of poor quality, that caries is common among this age group and that a substantial part of this group does not have healthy teeth. There is a need for effective motivational techniques which increases both oral hygiene and knowledge of oral hygiene. This paper aimed to show whether registering plaque in combination with a varying intensity of feedback had any effect on adolescent’s oral hygiene and their knowledge regarding oral hygiene. In addition, this paper aimed to measure adolescent’s appreciation regarding this type of motivational technique. Methodology The research population consisted of students (n=31) attending high school in Groningen. Of each student a front teeth QLF plaque registration was made which, based on fluorescence, automatically determined a Simple Plaque Score (ranging from 0 (little plaque) to 5 (substantial plaque)) and an R30 score (indicating areas with >30% higher fluorescence compared to clean teeth). One group received only general information regarding oral hygiene. A second group got to visually inspect their plaque registration and received personalized information regarding dental hygiene on top of the general information. A third group additionally received the plaque registration and the information per e-mail. The plaque registration scoring (both SPS and R30) were used as measurements for oral hygiene registration, in addition to four written knowledge tests. Measurements were taken before, one day after (knowledge only), and four weeks after intervention. Statistical significance (cut�off level set at p 0,05) was determined using Kruskall Wallis (between groups), Wilcoxon signed rank (within groups) and chi-square (regarding between group differences in gender and number of students with braces) tests. Results and conclusion Providing information on oral hygiene to adolescents was shown to lead to statistically significant increases in knowledge regarding oral hygiene in the short term (median level increased from 6,5 to 10,5) which did not deteriorate over time (median level longer term 10,0). Of the research population, 36% had SPS score of at least 3 at the baseline measurement. Oral hygiene did not show any statistically significant changes, but a trend can be identified wherein oral hygiene did improve in a substantial part of the research population. For both oral hygiene and knowledge regarding oral hygiene there were no statistically significant differences between groups, leading to the conclusion that general information regarding oral hygiene had a similar effect as personalized information and/or receiving a copy of the plaque registration. However, personalized information potentially improves knowledge regarding oral hygiene in the longer term. Receiving the information in form and substance as presented in this paper was evaluated as pleasant and useful by the population (grade 8,0 to 9,0): 77% of the population would recommend the information and 90% would recommend participation in similar projects to their peers. Suggestions for further research This paper emphasizes the need for additional attention regarding oral hygiene in adolescents as 36% of the population showed below average dental hygiene (SPS of at least 3) at the baseline measurement. Future research could replicate the current project on a larger scale, possibly including additional ways to transfer information that significantly influence oral hygiene.
