Sažetak
Introduction: The removable denture (RD) treatment outcome may depend on various factors, such as quality of new dentures, anatomical concerns of denture bearing area, previous denture experience, patients psychological traits, social features, cultural context, etc. (1, 2). Identification of factors contributing to a treatment success is a complex issue (3). In recent years there has been a shift to patient based measures as best methods for measuring patient centered outcome. Aim: To assess how and to which extent some factors contribute to improvement of oral health-related quality of life (OHRQoL) either by conventional complete denture (CD) therapy, or by implant- complete denture (I-CD) therapy (implants in the mandible). Methods: All patients were previous RD wearers. Sixty eight (68) patients (40 females, 28 males), 48-93 years old (68.58±11.17) received new, good quality CDs. Fifty four (54) patients (44 females, 10 males), 42-82 years old (67.3±9.39) received new, good quality, two locator retained I-CDs in the mandible versus complete denture in the maxilla. Quality of new dentures was assessed by one experienced specialist of prosthodontics, as prior inter-rater agreement (2 raters, 20 assessments) was excellent (Kappa=0.828). Education of patients was also recorded. There was no age, gender or education level differences between the CD and the I-CD groups (p>0.05). All patients completed 3 structured questionnaires: the short form of the oral health impact profile (OHIP-14) (4), the Orofacial esthetic scale (OES)(5) and the Chewing function questionnaire (CFQ) (6) twice: at baseline - prior treatment and 3 month after dentures had been delivered and all adjustments finished (after treatment scores). Baseline summary scores, after treatment summary scores and summary score differences were calculated for each questionnaire. The linear regression analysis was made with the OHIP score difference (improvement of OHRQoL) as dependent variable and the CFQ score difference, the OES score difference, age, level of education and gender as independent variables. Results: The OHIP summary score difference (OHRQoL improvement) was 13.97±10.26 (21.6%) in the CD wearers, and 15.78±8.59 (28.3%) in the I-CD wearers, respectively (Fig.1). The I-CD group improved better (p<0.01) OHRQoL, chewing function and orofacial esthetics, compared to the CD group (Fig. 1). In the CD wearers the regression model had only 2 significant factors: improvement of chewing ability (53.1%) and improvement of orofacial esthetics (10.3%), which explained 64% of the dependent variable (improvement of OHRQoL) (Table 1). Factors: age, gender and level of education were excluded (p>0.05). However, in the I-CD wearers only one factor: improvement of chewing function explained 18.6% of the variability of the dependent variable (OHRQoL improvement), while factors: esthetics, age, level of education and gender were excluded (P>0.05) (Table 2). Discussion: Both groups have already been RD wearers. All new dentures were of good quality. The I-CD group improved better OHRQoL, chewing function and orofacial esthetics. Improvement of OHRQoL in the I-CD wearers was explained by less than 20%, mostly by improvement of a chewing function, while influence of esthetics was negligible, as well as influence of gender, age and education. Obviously other factors may be more involved and that needs to be further investigated. In the CD group much higher percentage of OHRQoL improvement was explained by a regression model (>60%), however the most contributing factor was increase of a chewing ability (>50%), followed by increased esthetics. Conclusion: Different factors contribute to increase of OHRQoL with new dentures in the CD and I-CD wearers. Increase of a chewing function is the most important one in the both groups.
