Psychological disorders and quality of life in oral lichen planus patients and a control group.

OBJECTIVES: Oral lichen planus (OLP) is a common disease whose aetiopathogenesis is linked to psychological disorders. This study aims to determine the influence of anxiety and depression in OLP patients, define the perception of quality of life in these patients and check for potential differences between atrophic/ ulcerative and reticular lesions. MATERIALS AND METHODS: A group of 48 OLP patients and a control group of 40 patients were selected. In order to assess anxiety, depression and quality of life, Hospital Anxiety and Depression Scale (HADS) and Oral Health Impact Profile 14 (OHIP-14) tests were completed. RESULTS: OLP patients showed higher scores on HADS (anxiety p < 0.01, depression p < 0.05) and OHIP-14 (physical pain p < 0.05, psychological discomfort p = 0.001). Patients with reticular lesions obtained higher scores in HADS (anxiety p = 0.001, depression p < 0.001), whereas patients with atrophic/ ulcerative lesions obtained higher scores in OHIP-14 (p = 0.02). CONCLUSIONS: Psychological disorders play an important role as a trigger for OLP and are responsible for many relapses. Psychological support would be advisable in order to improve their mental health, as this would have a positive impact on their quality of life and would lead to a better progression of the disease.

Influence of clinical and psychological variables upon the oral health-related quality of life in patients with temporomandibular disorders

Background: To analyze the association between the OHIP-14 and the different subtypes making up the clinical and psychological axis obtained using the RDC/TMD. Material and Methods: 407 patients treated at the TMD unit of the Andalusian Healthcare Service were administered the Spanish version of the Research Diagnostic Criteria for Temporomandibular Disorders questionnaire (RDC/TMD), together with the Oral Health Impact Profile questionnaire (OHIP-14). The degree of association between the patients' score in the OHIP-14 and the clinical and biopsychosocial variables was analyzed through bivariate and multivariate analyses, specifically through linear regression. Results: 89.4% of the treated patients were women, while 10.6% were men, with an average age of 42.08 ± 14.9 years. The mean score and standard deviation for the OHIP-14 was 20.57 ± 10.73. A significant association (p < 0.05) was observed with the following variables: Axis I, jaw disability checklist, depression, somatization, perceived pain duration, and pain interference with activities of daily living Conclusions: The analysis of the relation between self-perceived health in patients with TMD, as measured by the OHIP-14, showed a R2 of 0.3979, with a higher Beta value for the association between the OHIP and patients with both myofascial pain and arthopathy, jaw disability, depression, a higher pain duration and a higher pain interference with activities of daily living (AU)

Prevalence of the different Axis I clinical subtypes in a sample of patients with orofacial pain and temporomandibular disorders in the Andalusian Healthcare Service

BACKGROUND: The main objective of this paper is to analyze the prevalence of each of the different clinical subtypes of temporomandibular disorders (TMD) in a sample of patients with this pathology. In addition, a second objective was to analyze their distribution according to gender. MATERIAL AND METHODS: To this end, the results of 1603 patients who went to the Unit of Temporomandibular Disorders in the Córdoba Healthcare District because they suffered from this pathology were analyzed. In order to diagnose them, the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were applied, analyzing the different Axis I subtypes (myopathy, discopathy and arthropathy) and obtaining the combined Axis I for each patient and the relation of all these variables according to gender. The null-hypothesis test confirmed the lack of connection between the gender variable and the different subtypes in the clinical analysis, and between the former and the combined Axis I of the RDC/TMD. RESULTS: The prevalence was high for the muscle disorders subtype in general, showing an 88.7% prevalence, while the presence of discopathies or arthropathies was much lower. Among discopathies, the most frequent ones were disc displacements with reduction, with 39.7% and 42.8% for the left and right temporomandibular joints (TMJ), respectively, while the prevalence of arthropathies was 26.3% for the right TMJ and 32.9% for the left TMJ. The bivariate analysis on the connection with gender reveals a pmore or equal 0.05 value for the muscle and arthralgia subtypes. CONCLUSIONS: The patients seen at the TMD Unit where mostly middle-aged women whose main clinical axis subtype was the muscle disorder subtype. For their part, both discopathies and arthropathies, although present, are much less prevalent

Application of an oral health-related quality of life questionnaire in primary care patients with orofacial pain and temporomandibular disorders

OBJECTIVES: To examine whether patients who report orofacial pain (OP) and temporomandibular disorders (TMD) have a poorer perception of their oral health-related quality of life and, if so, to what extent, and to analyze the association between oral health perception, sociodemographic variables and reported pain duration. Study DESIGN: 407 patients treated at the OP and TMD units in the Healthcare District of Cordoba, Spain, diagnosed following the standard criteria accepted by the scientific community - the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) - were administered the Spanish version of the Oral Health Impact Profile questionnaire (OHIP-14). Bivariate and logistic regression analyses were performed to determine the degree of association between the patients' OHIP-14 score and pain duration, pain intensity, and various sociodemographic variables. RESULTS: The observed distribution was 89.4% women and 10.6% men. The mean OHIP-14 score was 20.57 ± 10.73 (mean ± standard deviation). A significant association (p < 0.05) was found for gender, age, marital status, chronic pain grade, self-perceived oral health status and pain duration. CONCLUSIONS: The analysis of self-perceived oral health status in patients with OP and TMD, as measured by the OHIP-14, showed that oral health is perceived more negatively by women. Moreover, a one-point increase in the Chronic Pain Grade indicator increases the OHIP-14 indicator by 4.6 points, while chronic pain, defined as pain suffered by patients for one year or more, increases the OHIP-14 indicator by 3.2 points
