Oral Health-Related Quality of Life, Dry Mouth Sensation, and Level of Anxiety in Elderly Patients Rehabilitated with New Removable Dentures

Objective This study aimed to evaluate the influence of new complete dentures (CDs) and new removable partial dentures (RPDs) on oral health-related quality of life, dry mouth sensation, and anxiety level of their wearers. Materials and Methods In total, 20 complete edentulous patients (in both arches) that needed to be rehabilitated with new CDs, and 20 partial edentulous patients (in both arches) that needed to be rehabilitated with new RPDs, were included in this study. Each patient must wear the same pair of CDs or RPDs for more than 5 years. Oral health-related quality of life, dry mouth sensation, and level of anxiety were assessed by using the following questionnaires: Geriatric Oral Health Assessment Index (GOHAI), VAS (Visual Analog Scale) Xerostomia Questionnaire, and State-Trait Anxiety Inventory (STAI). These questionnaires were applied before oral rehabilitation (initially initial time point) and 3 months after insertion of new dentures (end time point). Statistical Analysis For the results of STAI-State, STAI-Trait, and GOHAI, the Wilcoxon test was applied to compare the time points. For the results of the VAS xerostomia questionnaire, two-way repeated measures ANOVA (analysis of variance) was applied, followed by the Tukey test. The p-values lower than 0.05 were considered statistically significant. Results/Conclusion For both groups, it was observed that 3 months after the insertion of new removable dentures: (1) there was an increase in oral health-related quality of life; (2) there was a reduction in anxiety (trait anxiety and state anxiety); and (3) there was a perception of greater salivation.

Voice Outcomes after Radiotherapy for Laryngeal Cancer

Objective The study was aimed to assess changes in voice outcomes after radiotherapy in laryngeal cancer patients. Materials and Methods The study included 60 laryngeal cancer patients treated with definitive radiotherapy or chemoradiotherapy between 2005 and 2012. The primary endpoint of this study was to assess abnormalities of the patients’ voices after the treatment. The Thai version of the Voice Handicap Index (VHI) and xerostomia questionnaire were conducted by telephone. Videostroboscopic examination was done to objectively assess voice outcomes. Results The median age of patients was 63 years. Most patients had glottic cancer (84.1%) and T1–2 disease (84.1%). The median time from treatment to the study was 46 months. In terms of the total VHI score, most patients were in the normal and slight handicap groups (22% and 71.4%, respectively). Only 4.8% and 1.6% of the patients were in moderate and severe handicap group, respectively. Twenty-eight patients had significant xerostomia. Videostroboscopy examination was done in 23 patients and most common findings were telangiectasia (95.7%), abnormal mucosal wave (47.8%), and abnormal glottic closure configuration (34.8%). Regarding total VHI score, lower radiation dose, conventional radiation dose per fraction, longer period after treatment, and significant xerostomia status were significantly correlated with worse voice outcomes. There were no statistically significant correlations between the videostroboscopic findings and VHI scores. Conclusion Voice outcomes in most of laryngeal cancer patients treated with radiotherapy had a normal or mild handicap at more than 1 year of follow-up. Only 4.8% and 1.6% of the patients had moderate and severe voice outcome handicap, respectively.

The role of xerostomia in burning mouth syndrome: a case-control study

Objective : To assess the efficacy of anti-xerostomic topical medication (urea 10%) in patients with burning mouth syndrome (BMS). Method : Thirty-eight subjects diagnosed with BMS according to the International Association for the Study of Pain guidelines were randomized to either placebo (5% sodium carboxymethylcellulose, 0.15% methyl paraben, and 10% glycerol in distilled water qsp 100 g) or treatment (urea 10%) to be applied to the oral cavity 3-4 times per day for 3 months. The patients were evaluated before and after treatment with the following instruments: the EDOF-HC protocol (Orofacial Pain Clinic – Hospital das Clínicas), a xerostomia questionnaire, and quantitative sensory testing. Results : There were no differences in salivary flow or gustative, olfactory, or sensory thresholds (P>0.05). Fifteen (60%) patients reported improvement with the treatments (P=0.336). Conclusion : In conclusion, there were no differences between groups, and both exhibited an association between reported improvement and salivation.
