World Workshop on Oral Medicine VIII: Development of a core outcome set for dry mouth: a consensus study.

Objective: This study aimed to develop a consensus-based core outcome set (COS) to be used in clinical trials assessing dry mouth interventions.

Study Design: Through 2 systematic literature reviews and interviews with dry mouth patients, we identified relevant outcome domains for dry mouth assessment. A Delphi survey was presented to health care providers attending the American Academy of Oral Medicine annual meeting in Memphis, Tennessee, USA, on May 2022 (n = 104) and 10 dry mouth patients at Cork University Dental School and Hospital, Republic of Ireland.

A Mutation in Is Associated with Multiple Supernumerary Cusps and Root Maldevelopment.

Background: Enamel knots and Hertwig epithelial root sheath (HERS) regulate the growth and folding of the dental epithelium, which subsequently determines the final form of tooth crown and roots. We would like to investigate the genetic etiology of seven patients affected with unique clinical manifestations, including multiple supernumerary cusps, single prominent premolars, and single-rooted molars.

Methods: Oral and radiographic examination and whole-exome or Sanger sequencing were performed in seven patients.

Validity and responsiveness of pain rating scales in patients with chronic oral mucosal diseases.

Objectives: To validate the Visual Analog Scale (VAS) and Numerical Rating Scale (NRS) for measuring pain intensity in chronic oral mucosal diseases.

Methods: Secondary analyses of data including the VAS, NRS, demographic, clinical and quality-of-life outcomes at baseline and 4-month follow-up were retrieved from a clinical study of chronic oral mucosal diseases. Construct and criterion validity and responsiveness of the VAS and NRS were assessed through testing hypotheses based upon strength of Spearman's correlation coefficients.

The patient acceptable symptom state in oral lichen planus: identification of cut-off threshold scores in measures of pain and quality of life.

Objectives: To establish thresholds of pain and quality of life scores corresponding to patient acceptable symptom state (PASS) in patients with oral lichen planus (OLP) and to assess demographic and clinical factors associated with achieving the PASS.

Methods: Prospective data from baseline and 4-month follow-up including Visual Analogue Scale (VAS), Numerical Rating Scale (NRS), 14-item Oral Health Impact Profile (OHIP-14) and 15-item and 26-item Chronic Oral Mucosal Disease Questionnaire (COMDQ-15; COMDQ-26) were collected from 281 patients with OLP. An anchoring approach based upon the patient's opinion on acceptability of OLP status was applied.

Health-related quality of life and its associated predictors in patients with oral lichen planus: a cross-sectional study.

Objectives: To investigate levels of quality of life (QoL) and determine associated predictors in patients with oral lichen planus (OLP).

Materials And Methods: A total of 300 patients with OLP at one tertiary Oral Medicine clinic in the UK were recruited in a cross-sectional study from January 2018 to July 2019. The 15-item Chronic Oral Mucosal Disease Questionnaire (COMDQ-15) and 14-item Oral Health Impact Profile (OHIP-14) were used to assess the level of QoL related to OLP.

Evaluating the measurement properties of patient-reported outcome measures in radiotherapy-induced xerostomia.

Objective: Radiotherapy-induced xerostomia (RIX) is one of the most common adverse effects of radiotherapy to the head and neck, and a major determinant of survivors' quality of life. A number of patient-reported outcome measures (PROMs) have been used in clinical trials of therapeutic interventions for RIX; however, little is known regarding their measurement properties and methodological quality.

Methods: We conducted a systematic literature search in Embase, MEDLINE and PsycINFO for articles published up to May 2019 and evaluating at least one measurement property of PROMs relevant to RIX.

Meaningful improvement thresholds in measures of pain and quality of life in oral lichen planus.

Objectives: To evaluate the responsiveness of measures of pain and oral health-related quality of life (OH-QoL) in patients with oral lichen planus (OLP) and to determine thresholds for minimal important change (MIC) and minimal important difference (MID) for use in this patient population.

Methods: Data from baseline and 4-month follow-up including Visual Analog Scale (VAS), Numerical Rating Scale (NRS), 14-item Oral Health Impact Profile (OHIP-14), 15-item and 26-item Chronic Oral Mucosal Disease Questionnaire (COMDQ-15; COMDQ-26) were collected from 157 patients with OLP. Responsiveness was assessed by testing hypotheses and calculating the area under the curve.

Validation of the HADS and PSS-10 and a cross-sectional study of psychological status in patients with recurrent aphthous stomatitis.

Objectives: To validate the Hospital Anxiety and Depression Scale (HADS) and the 10-item Perceived Stress Scale (PSS-10) for use in clinical studies of recurrent aphthous stomatitis (RAS) and to provide cross-sectional assessment of anxiety, depressive, and distress symptoms and perceived stress in patients with RAS.

Methods: The validity and reliability of the HADS and PSS-10 were evaluated in 120 individuals with RAS through confirmatory factor analysis and calculation of Cronbach's alpha and omega coefficients. The prevalence of comorbid anxiety, depression, distress, and moderate-to-high perceived stress, and their association with demographics and clinical factors were assessed through cutoff scores of the HADS and PSS-10 and bivariate analyses, respectively.

Validation of the HADS and PSS-10 and psychological status in patients with oral lichen planus.

Objectives: To validate the Hospital Anxiety and Depression Scale (HADS) and the 10-item Perceived Stress Scale (PSS-10) for use in patients with oral lichen planus (OLP) and to provide cross-sectional analysis of anxiety, depressive and distress symptoms in patients with OLP.

Methods: Validity and reliability of both instruments were assessed in 260 participants with OLP in one tertiary oral medicine centre through confirmatory factor analysis and calculation of reliability coefficients. Prevalence, clinical and demographic predictors of the presence of psychological symptoms in OLP were calculated and identified using multivariated logistic regression.

Development and validation of a short version of Chronic Oral Mucosal Disease Questionnaire (COMDQ-15).

Background: The adoption of the Chronic Oral Mucosal Disease Questionnaire (COMDQ) into clinical practice has been low, despite its rigorous development process. A potential limitation of the COMDQ is the high response burden to patients. Therefore, the aim of the present study was to develop and validate a short version of the 26-item COMDQ.

Measurement properties of patient-reported outcome measures in radiotherapy-induced trismus.

Trismus or lockjaw is the reduction in mouth opening. Radiotherapy-induced trismus occurs when the masticatory muscles are within range of radiation treating head and neck cancer, resulting in muscular fibrosis and trismus. We aim to assess the measurement properties of available validated patient-reported outcome measures relevant to radiotherapy-induced trismus in head and neck cancer patients.

Patient-reported outcome measures in oral lichen planus: A comprehensive review of the literature with focus on psychometric properties and interpretability.

Objective: To review the range of patient-reported outcome measures (PROMs) used in clinical studies of patients with oral lichen planus (OLP) and to assess their psychometric properties and interpretability.

Methods: Literature searches were performed on MEDLINE, EMBASE and Web of Science databases (1990-September 2016) to retrieve relevant studies related to the development, psychometric testing and/or use of PROMs assessing oral symptoms, psychosocial status and quality of life in individuals with OLP. The identified PROMs were then categorised by concept measured and assessed for instrument characteristics and evidence for psychometric properties and interpretability.
