Samenvatting
OBJECTIVE:
Standard periodontal parameters do not quantify the surface of inflamed periodontal tissue in mm², while this is preferred to assess the impact of periodontitis on systemic health, especially in epidemiological studies. The Periodontal Inflamed Surface Area index (PISA) calculates this surface from pocket depth measurements. The present study uses the PISA to examine the performance of split-mouth examinations (SME-PISA) and the Ramfjord Index Teeth (RIT-PISA) to assess the total full-mouth inflammatory burden posed by periodontitis in adults.
METHODS:
In this retrospective cross-sectional study, the SME-PISA (two contralateral quadrants) and RIT-PISA (six predefined teeth) were calculated based on 300 periodontal records obtained between 2014-2015 from the University Medical Center Groningen and subsequently compared with the full-mouth examinations (FME-PISA). Linear regression, Pearson's correlation, Intraclass Correlation Coefficients (ICC agreement) and Bland-Altman plots with 95% limits of agreement (LoA) were used to determine the correlation and agreement between the SME-PISA, RIT-PISA and FME-PISA. For comparison, the agreement between SME, RIT and FME was also calculated for the CPC-AAP definition of periodontitis using weighted Cohen's Kappa.
RESULTS:
SME-PISA and RIT-PISA showed excellent correlation with FME-PISA (r=0.97, p<0.001 and r=0.89, p<0.001, resp.) and also excellent agreement (ICC=0.97, p<0.001; LoA±334 mm² and ICC=0.89, p<0.001; LoA±589 mm², resp.). Linear regression analysis revealed that SME-PISA and RIT-PISA were positively associated with FME-PISA (β=1.87; p<0.001 and β=3.30; p<0.001, resp.). Using the CPC-AAP definition, weighted kappa for SME and RIT with FME was 0.68 (95% CI=0.56-080) and 0.62 (95% CI=0.51-0.74), resp.
CONCLUSIONS:
These findings support the use of SME-PISA and RIT-PISA in order to adequately estimate the total amount of periodontal inflammatory burden in epidemiological studies, with SME-PISA presenting the most accurate agreement with FME-PISA. However, from a cost-effectiveness perspective, the RIT-PISA may be the best option, because it conserves time and limits patient discomfort.
