title: Short-Term Assessment of the OHIP-14 Scale on Denture Wearers Using Adhesives.
abstract: OBJECTIVE
  The purpose of this study was to assess differences of the Oral Health Implant Profile-14 (OHIP-14) scale over a month and determine association with gender, supporting tissues (KIS), and denture base (KID) among patients wearing complete dentures using denture adhesives.
  
  
  METHODS
  Sixteen denture wearers, candidates for a new set of complete dentures, were selected. OHIP-14 scores were recorded at the beginning of the study, 6 weeks after fitting of the new set (T0 ), 15 days (T1 ), and finally 30 days (T2 ) after daily use of a denture adhesive as instructed. The KIS and KID were clinically examined and rated according to the Kapur Index. Statistical analyses were based on repeated-measures ANOVA, Mann-Whitney test, regression analysis, and Friedman test at a = 0.05.
  
  
  RESULTS
  The OHIP-14 scale was found to have a high reliability (alpha = 0.847) and a high test-retest consistency (ICC = 0.889); however, domain 1 had the lowest item-total correlation (rho = 0.144) and item 7 a negative one (rho = -0.414). Trend analysis indicated a significant negative linear trend over time (slope = -3.156, p = 0.002), while repeated-measures ANOVA showed differences in OHIP-14 between T2 and T1 (p = 0.003) or T0 (p = 0.005) intervals. OHIP-14 groups were found to be positively associated with KIS (p = 0.010) and negatively with KID (p = 0.047) groups, but not with gender (p = 0.272).
  
  
  CONCLUSIONS
  The study shows that OHIP-14 has a high internal reliability and consistency when applied to new denture wearers, and its score decreases if denture adhesives are used for at least 15 days. Low KIS and high KID contributes to this trend. Some OHIP-14 items are more associated than others with the total score trend over time.
