The distribution of DPSI-indices varied between the dental practices (p < 0.01, Kruskal-Wallis test). The DPSI is the lowest in dental practice #3. There was no difference in patients moving from DPSI category C to category A or B between the dental practices (p > 0.05 Chi-square test), nor for patients moving from DPSI category A or B to category C (p > 0.05, Chi-square test). The DPSI of patients in age group 40–64 years was higher than of patients in age category 18–39 years (p < 0.01, Mann-Whitney U-test). There was no difference in DPSI between the different socioeconomic groups (p > 0.05, Kruskal-Wallis test). Smokers and non-smokers have the same distribution of DPSI-indices (p > 0.05, Mann-Whitney U-test). This is also the case for patients with and without diabetes (p > 0.05, Mann-Whitney U-test). | |||||
Specifications of measure | |||||
Data source | Clinical records dental practice | ||||
*) Assessment of DPSI | The DPSI-index is the highest measured score for measures in all six sextants [28] DPSI category A DPSI index 0 - no pockets deeper than 3 mm, no bleeding on probing, no calculus, no overhangs of restorations DPSI index 1 - same as in index 0, but bleeding on probing DPSI index 2 - same as in index 1, but with calculus and/or overhanging restorations DPSI category B DPSI index 3 negative - pockets of 4 or 5 mm with bleeding on probing WITHOUT gingival recession(s) above the deepened pocket(s) DPSI category C DPSI index 3 positive - pockets of 4 or 5 mm with bleeding on probing WITH gingival recession(s) above the deepened pocket(s) DPSI index 4 - one or more pockets of at least 6 mm in depth | ||||
Numerator/denominator | Numerator: a) number of patients that moved from DPSI-category A or B to category C b) number of patients that moved from DPSI-category C to A or B at reassessment Denominator: total number of patients with a repeated assessment of the DPSI-score | ||||
Inclusion criteria | • at least one oral health examination a year • at least 2 years registered in the dental practice • ≥18 years old |
