OHRQoL and chewing function in three different removable denture options

Purpose/Aim: The aim of the study was to assess improvement of oral health-related quality of life (OHRQoL) and chewing function (CF) among three groups [complete denture patients (CD group), patients who received CDs in the maxilla and CDs supported by Mini Dental Implants (MDI) in the mandible (CD-MDI group), and patients who received CDs in the maxilla and long saddle removable partial dentures - Kennedy Class I in the mandible (CD-RPD group). Aim was also to determine changes of post-treatment scores one year after the therapy. Materials and Methods: Croatian version of OHIP14 and chewing function questionnaire (CFQ) consisting of 10 questions (scores 0-4 ; 0=no difficulties, 4=highest difficulties) were completed at three occasions: before treatment, 2- 3 month after treatment, and one-year post treatment. The CD group comprised 40 females and 28 males, mean age 69, 58 years (±11, 17), CD-RPD group comprised 32 females 32 and 26 males mean age 66 years (±8, 004), while CD-MDI comprised 44 females and 6 males, mean age 66, 72 years (±9, 34). No significant age differences between groups was observed (P>0.05). Results: All groups significantly reduced OHIP scores and CFQ scores after the treatment (P<0.01) with the highest reduction of the CFQ scores in the CD-MDI group (-21.6 ± 6.3) compared to the CD (-11.705 ± 5.86) and the CD-RPD group (-14.07 ; ±8.51) ; (F=30, 39, P<0.001). The highest reduction of the OHIP scores was also recorded in the CD-MDI group (-19.2 ± 10.52), compared to the CD-RPD (-16.24 ±7.5) and the CD groups (-13.71 ± 9.9) (F=4.95 ; P=0.008). The CD-MDI group improved CF and OHRQoL signifficantly better than the CD group (Sheffe post hoc). Multivarate analysis revealed that only different prosthodontic rehabilitation (CD: CD- MDI: CD-RPD) elicited significant effects (p<0.01), while age, gender and level of education did not (p>0.05). At the one-year stage, both CFQ (11.94:15.11) and OHIP scores (7.76:9.5) significantly increased (worsened) in the CD group (p<0.01). In the CD-RPD group scores also increased, but significantly only for the OHRQoL (p<0.05), while in the CD-MDI group CFQ scores further decreased (p<0.01). Conclusions: Among the three observed prosthodontic rehabilitation options (CDs, CD-RPDs and CDMDIs9, the CD-MDI group elicited best effects, which remained consistent within one-year post treatment, or even improved.
