Abstract

Purpose: To investigate the effect of missing teeth on patients' oral health-related quality of life (OHRQoL). Materials and Methods: A total of 151 patients participated in this prospective bicenter clinical study (mean age: 64.7 +/- 10.5 years;71 women). Four subgroups were defined based on the number of missing teeth. OHRQoL was assessed using the German version of the Oral Health Impact Profile-49/53 (OHIP-G49/53) and visual analog scale (VAS) questionnaires. The effect of missing teeth on OHIP (total and dimension scores) and VAS scores before and after prosthetic treatment was investigated at baseline (T-0), 1 week (T-1), and 3 months (T-2) after prosthetic treatment. Scores were analyzed using Kolmogorov-Smirnov, Kruskal-Wallis, and Mann-Whitney U tests. Correlations were assessed using Spearman p correlation. The level of significance was set at P= .05. Results: Initial OHIP and VAS scores were highest for patients with 11 to 28 missing teeth. Scores improved among all groups between To and T-1/T-2. After prosthetic rehabilitation (T-1), improvements in total OHIP scores were greatest for patients with no missing teeth or with 11 to 28 missing teeth. Patients with no missing teeth or with 1 to 4 missing teeth before treatment had the lowest posttreatment OHIP scores. Total OHIP scores among the groups were in the same value range (P> .185). No direct correlation was found between the VAS and total OHIP scores. Conclusion: OHIP and VAS scores for OHRQoL were associated with the number of missing teeth. Prosthetic treatment resulted in improved OHRQoL and oral function among all groups. The use of a VAS yielded additional detailed information.
