Does a mandibular RDP and new maxillary CD improve masticatory efficiency and quality of life in patients with a mandibular Kennedy class I arch?

Abstract

Objectives To evaluate the change in masticatory efficiency and quality of life of patients treated with mandibular Kennedy class I removable partial dentures (RPDs) and maxillary complete dentures at the Department of Dentistry of the Federal University of Rio Grande do Norte. Materials and methods A total of 33 Kennedy class I patients were rehabilitated with maxillary complete dentures, and mandibular RPDs were selected for this non-randomized prospective intervention study. The patients had a mean age of 59.1 years. Masticatory efficiency was evaluated by colorimetric assay using fuchsin capsules. The measurements were conducted at baseline and 2 and 6 months after prosthesis insertion. Quality of life was evaluated using the Oral Health Impact Profile (OHIP-14) at baseline and 6 months after denture insertion. The Kolmogorov-Smirnov normality test was applied. Masticatory efficiency was evaluated by repeated measures ANOVA. Oral health-related quality of life was compared using the paired t test.Results There was no statistically significant difference in masticatory efficiency after denture insertion (p =0.101). Significant differences were found (p=0.010) for oral healthrelated quality of life. A significant improvement in psychological discomfort (p<0.01) and psychological disability (p<0.01) was observed. Mean difference value (95 % confidence interval) was 6.8 (3.8 to 9.7) points, reflecting a low impact of oral health on quality of life, considering the 0-56 range of variation of the OHIP-14 and a Cohen's d of 1.13. Conclusion According to the results of the present study, rehabilitation with Kennedy class I RPDs and complete dentures did not influence masticatory efficiency but improved oral health-related quality of life. Clinical relevance The association between the patient's quality of life and the masticatory efficiency is important for treatment predictability.

Impact of rehabilitation versus edentulism on systemic health and quality of life in patients affected by periodontitis: A systematic review and meta‐analysis

“…Meta‐analysis of OHIP‐14 included four articles (Cakir et al, 2014; Knipfer et al, 2014; De Carvalho Dias et al, 2016; Toia et al, 2019). The overall difference between baseline and post‐treatment values was 10.52 (95% CI: [6.38; 14.66], p < .01, I 2 = 98.09%) (Figure 3a).…”

“…Moreover, the absence of edentulism rehabilitation was reported to be related to poorer nutritional status (Saarela et al, 2014(Saarela et al, , 2016. This may be related to the impact of oral rehabilitation on the masticatory efficiency (De Carvalho Dias et al, 2016;Ribeiro et al, 2017;Yamamoto & Shiga, 2018;Tôrres et al, 2019), which seems to improve in particular following implant-retained rehabilitation (Marcello-Machado et al, 2018). However, nutritional status is complex and may not be only determined by the dental status.…”

“…The impact of partial edentulism rehabilitation by means of different prosthetic modalities was assessed in seven studies with various study designs, employing different OHRQoL questionnaires, as well as measures of masticatory efficiency, symptoms, and patient satisfaction (Jones et al, 2003;Wolfart et al, 2005Wolfart et al, , 2014Ha et al, 2012;Cakir et al, 2014;De Carvalho Dias et al, 2016;Khan et al, 2019).…”

The impact of a newly constructed removable denture on the objective and subjective masticatory function

“…This assessment has the advantage of being an unbiased evaluation, which may reflect the actual status of the masticatory function. The results show that the method used was sufficiently sensitive to detect the effect of denture rehabilitation.A previous study that measured the masticatory efficiency indicated the importance of a methodology that can detect small differences between treatments [31]. By using a test gummy jelly and a fully automatic measuring device [23], we were able to quantify the effect of the new denture treatment.…”

Functional oral health‐related quality of life impact: A systematic review in populations with tooth loss

“…In total, 3,653 potential publications were identified 17 . After exclusion of duplicate articles, incomplete studies, articles not written in English language and articles using not suitable scores to characterise Oral Function, 78 publications reported baseline or cross‐sectional data with partial or complete tooth loss (see Figure 1 for full population identification procedure) 18‐62 …”
