Abstract
ObjectivesTo analyze the oral health-related impact profile in patients treated with three different types of dental prosthesis in student courses.Materials and MethodsThis prospective bicenter clinical trial was conducted with 151 patients being treated with fixed (n = 70), removable (n = 61), or telescopic dental prostheses (n = 20) in clinical student courses of two German universities from October 2018 to October 2019. All patients completed three standardized German versions of the Oral Health Impact Profile (OHIP-G49/53) before prosthetic treatment (T0), at control after 1 week (T1), and after 3 months (T2), divided into five dimensions: (a) appearance, (b) oral function, (c) psychosocial impact, (d) linguistic limitations, and (e) orofacial pain. Data were analyzed with Kolmogorov–Smirnov, Wilcoxon signed-rank, Kruskal–Wallis, Mann–Whitney, and Cronbach’s alpha tests.ResultsWithin T0–T1 and T0–T2, greater improvements were determined for removable compared with fixed dental prostheses for the dimensions’ oral function (p ≤ 0.014), linguistic limitations (p ≤ 0.016), and appearance (p ≤ 0.003). No significant differences were found between fixed and telescopic dental prostheses (p ≥ 0.104) or between removable (partial dental prosthesis with clasps and complete dental prosthesis) and telescopic dental prostheses (p ≥ 0.100). Within T1–T2, a significant improvement in orofacial pain could be determined (p = 0.007).ConclusionsRestorations presented an improvement in oral health-related quality of life. Removable dental prostheses showed better improvement than fixed ones in various dimensions.Clinical relevanceKnowledge about the influence of oral health-related quality of life on the three different types of prosthesis used in student courses can be of decisive help in dental consultations.
Highlights
Overall quality of life (QoL) depends crucially on the oral health-related quality of life (OHRQoL) [1]
The scientific literature generally shows an improvement in oral health-related impact profile through prosthetic restorations, this appears to depend on the restoration type [11]
For question 3/10 and question 1, the greatest improvement was observed between T0 and T1 and for question 1 between T0 and T2, followed by question 46 between T0 and T1 and question 51 between T0 and T1
Summary
Overall quality of life (QoL) depends crucially on the oral health-related quality of life (OHRQoL) [1]. An OHIP questionnaire represents a subjective evaluation of individual oral health and, in some cases, of patients’ expectations, feelings, and satisfaction with regard to a. The scientific literature generally shows an improvement in oral health-related impact profile through prosthetic restorations, this appears to depend on the restoration type [11]. In two studies on prosthetic restorations, a significant improvement in oral health-related impact profile was recorded for patients with complete dental prostheses; one of the studies investigated patients in student courses [4, 17]. Treatment with different double crown removable dental prostheses improves the oral health-related impact profile [18]. Patients with removable dental prostheses, show a worse oral healthrelated impact profile than patients with fixed restorations [12]
