“…Upon arrival at the laboratory, participants were instructed to brush their teeth as previously described. The Portuguese versions of the Xerostomia Inventory 5 (SXI‐5‐PL) and the Oral Health Impact Profile (OHIP‐14‐PT; Amaral, Marques, Thomson, Vinagre, & da Mata, ; Amaral, Sanches, et al, ) questionnaires were administered to the patients for establishing their baseline values before the usage of one of the systems. The original SXI is a questionnaire comprising five questions from which the respondent can choose from three available answers.…”

Objectives To investigate the impact of gustatory stimulants of salivary secretion (GSSS) on Sjögren's syndrome patients’ self‐perception of xerostomia, oral health‐related quality of life (OHRQoL) and salivary secretion. Methods A total of 110 Sjögren's syndrome patients were randomly allocated to be treated with either a malic acid lozenge or a citric acid mouthwash and then crossed over. Before and after the interventions, the Xerostomia Inventory 5 (SXI‐5‐PL) and the Oral Health Impact Profile (OHIP‐14‐PT) questionnaires (both in the Portuguese language) were administered to patients. Unstimulated, mechanical and gustatory‐stimulated salivary flows were determined. Repeated measures and between‐subject analyses were performed. Statistical significance was set at 5%. Results After the intervention and within each group, both GSSS elicited a reduction in the SXI‐5‐PL and OHIP‐14‐PT scores and an increase in salivary output, significant in the malic acid lozenge group. The malic acid treatment resulted in a greater effect size and percentage improvement than citric acid mouthwash. The malic acid lozenge also produced a significant greater salivary output than the citric acid rising solution. Conclusions In Sjögren's syndrome patients, lozenges containing malic acid increased saliva production and xerostomia relief, resulting in improved quality of life.

“…Dry mouth perception was evaluated through the Portuguese version of the Shortening the Xerostomia Inventory (SXI-5), a five-question tool where each question is scored by 0 = never, 1 = occasionally and 2 = frequently. The scores from the five questions are summed, with the result representing the degree of xerostomia the subject feels [37].…”

Parkinson’s Disease, Periodontitis and Patient-Related Outcomes: A Cross-Sectional Study

Background and objectives: People with Parkinson’s disease (PD) may be at risk of having bad periodontal status. A consistent periodontal examination is critical to investigate how it impacts on PD quality of life. We aimed to assess the periodontal status of people with PD, and its association with quality of life and self-perceived xerostomia. Materials and Methods: To this end, from February to March 2020, we consecutively enrolled 28 PD individuals, and motor and non-motor symptoms of PD were assessed using the Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS). We performed full-mouth periodontal examination and gathered information on self-perceived quality of life in PD, oral health impact profile (OHIP-14) and xerostomia. Results: The prevalence of periodontitis was 75.0% and most cases were identified as severe (46.4%). Upper extremity rigidity, hand posture and kinetic tremors were significantly correlated with worse periodontal status. PDQ-8 showed to be correlated with self-perceived oral health-related quality of life and xerostomia levels. Conclusions: This group of people with PD had a high prevalence of periodontitis. Deteriorated levels of the upper extremities in advanced stages of PD were associated with worse periodontal status and hygiene habits. Quality of life in PD appears to be associated with self-perceived OHRQoL and xerostomia.

“…For each statement, participants selected a response along a three-point scale, with the response "never" scoring 0 point, "occasionally" 1 point and "frequently" 2 points. The scores from the 5 questions are summed, with the result representing the degree of Xerostomia the subject feels, and higher scores representing more severe xerostomia (Amaral, Marques, Thomson, Vinagre, & da Mata, 2017).…”

Aim To investigate the impact of periodontal disease perception and oral health‐related quality of life (OHRQoL), towards the initial periodontal treatment adherence (IPTA). Material and Methods This prospective study included 571 patients (274 males and 297 females, mean age 63.1 ± 14.5) with periodontal disease, from the Study of Periodontal Health in Almada‐Seixal (SoPHiAS). We assessed the potential connections, between sociodemographic characteristics, oral hygiene behaviours, periodontal measures, the Brief Illness Perception Questionnaire (IPQ) and the Oral Health Impact Profile (OHIP‐14), through a structural equation modelling (SEM). Multivariate logistic regression assessed significant oral health‐related variables towards IPTA. Results Overall, 265 participants had IPTA (46.4%). The SEM had a good fit to the data on all six latent variables (χ2 = 2.221, CFI = 0.921, RMSEA = 0.0.046). Multivariate analysis for IPTA indicated Treatment Control (Odds Ratio [OR] = 1.07) and Identity domains of Brief‐IPQ (OR = 1.10) and Functional Limitation domain of OHIP‐14 (OR = 1.60) as significant predictors. The obtained tool had a satisfactory prediction of IPTA (61.1%). Conclusions Initial periodontal treatment adherence is influenced by patient's perception on periodontal disease treatment and identity domains and by functional impact domain of OHRQoL. Future studies shall investigate the effect of modelling these domains on therapeutic success and public health strategies.
