A modified Newton classification for denture stomatitis.

The effectiveness of denture stomatitis (DS) treatment should be evaluated by associating clinical and mycological parameters. Although widely used in clinical studies, the Newton classification does not accurately represent the degree of severity of palatal inflammation in terms of extent of the lesions and intensity of the erythema. Therefore, a modified Newton classification has been proposed considering the coverage area of palatal inflammation and the erythema level. This consistent and direct ranking will help standardise randomised clinical trials, as well as the statistical comparison among blind evaluations of the obtained scores within and between studies.

Occlusal marking film for accurate interference assessments of removable partial denture frameworks: A dental technique.

A technique is described for detecting areas of interference for removable partial denture frameworks. An occlusal marking film is placed between the misfitted abutment teeth and framework region. Gentle pressure is applied to seat the framework, and the exact areas of interference are seen on removal. With this clean, rapid, cost-effective, and straightforward approach, areas of interference can be precisely adjusted for complete seating of the removable partial denture framework.

Impact of rehabilitation with removable complete or partial dentures on masticatory efficiency and quality of life: A cross-sectional mapping study.

STATEMENT OF PROBLEM: Tooth loss directly affects mastication, cognitive function, and oral health-related quality of life (OHRQoL). Complete dentures (CDs) and removable partial dentures (RPDs) represent a common oral rehabilitation approach. However, studies addressing the impact of removable dentures on replacing missing teeth are lacking. PURPOSE: The purpose of this clinical study was to evaluate whether the OHRQoL, the jaw function limitation (JFL), and the masticatory efficiency of CD and RPD wearers are similar to those of patients with natural teeth and to evaluate whether wearing removable dentures can predict an effect on the OHRQoL, JFL, and masticatory efficiency of their wearers. MATERIAL AND METHODS: The Oral Health Impact Profile (OHIP-14) questionnaire and the JFL scale were used to measure OHRQoL and JFL. Masticatory efficiency was analyzed by using a subjective color-mixing index for the chewing gum bolus and shape index and an objective colorimetric analysis by using a software program ViewGum. Data were analyzed with Kruskal-Wallis and post hoc Dunn tests, followed by multiple linear regression (α=.05). RESULTS: The results from OHIP-14 evidenced that both denture groups presented a low impact on OHRQoL. JFL was higher for all denture wearers. For the subjective color-mixing analysis, the control and RPD groups presented better masticatory efficiency than CD wearers. Colorimetric analysis evidenced better masticatory efficiency for the control group, who differed from the CD and RPD groups. Wearing RPDs was a predictor of impaired JFL and OHRQoL, and the use of CDs was a predictor of impaired JFL and masticatory efficiency. CONCLUSIONS: Despite being rehabilitated, CD and RPD wearers still had impaired OHRQoL, JFL, and masticatory efficiency. Also, the use of these prostheses can predict a negative effect on these 3 variables.
