Pharmacological treatment of oro-facial pain - health technology assessment including a systematic review with network meta-analysis.

This health technology assessment evaluated the efficacy of pharmacological treatment in patients with oro-facial pain. Randomised controlled trials were included if they reported pharmacological treatment in patients ≥18 years with chronic (≥3 months) oro-facial pain. Patients were divided into subgroups: TMD-muscle [temporomandibular disorders (TMD) mainly associated with myalgia]; TMD-joint (TMD mainly associated with temporomandibular joint pain); and burning mouth syndrome (BMS). The primary outcome was pain intensity reduction after pharmacological treatment. The scientific quality of the evidence was rated according to GRADE. An electronic search in PubMed, Cochrane Library, and EMBASE from database inception to 1 March 2017 combined with a handsearch identified 1552 articles. After screening of abstracts, 178 articles were reviewed in full text and 57 studies met the inclusion criteria. After risk of bias assessment, 41 articles remained: 15 studies on 790 patients classified as TMD-joint, nine on 375 patients classified as TMD-muscle and 17 on 868 patients with BMS. Of these, eight studies on TMD-muscle, and five on BMS were included in separate network meta-analysis. The narrative synthesis suggests that NSAIDs as well as corticosteroid and hyaluronate injections are effective treatments for TMD-joint pain. The network meta-analysis showed that clonazepam and capsaicin reduced pain intensity in BMS, and the muscle relaxant cyclobenzaprine, for the TMD-muscle group. In conclusion, based on a limited number of studies, evidence provided with network meta-analysis showed that clonazepam and capsaicin are effective in treatment of BMS and that the muscle relaxant cyclobenzaprine has a positive treatment effect for TMD-muscle pain.

Assessment of self-reported sleep disturbance and psychological status in patients with burning mouth syndrome.

OBJECTIVES: To investigate the quality of sleep of patients with primary burning mouth syndrome (BMS) compared with a control group. METHODS: A total of 70 patients with primary BMS and 70 control subjects were enrolled in the study. The severity of pain was evaluated with a Visual Analogue Scale (VAS). Four validated questionnaires were used to investigate the psychological profile of each patient: the Hospital Anxiety and Depression Scale, the Oral Health Impact Profile-14 (OHIP-14), the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (EES). RESULTS: Poor sleep quality was present in 67.1% patients with BMS vs. 17.1% in control subjects (P ≤ 0.001). For patients with BMS, total data resulting from the PSQI correlated with results obtained by the EES (P ≤ 0.001), VAS pain (P ≤ 0.001), localization (P = 0.01), HAD-A (P = 0.001) and HAD-D (P = 0.001). Logistic regression analysis showed that an increase of one point in each depression score (HAD-D) made the chances of PSQI 1.26 times more likely, with a 95% confidence interval (CI = 1.03-1.55). CONCLUSIONS: Patients with primary BMS exhibited significant decreases in sleep quality compared with the control group.

Orofacial pain symptoms and associated disability and psychosocial impact in community-dwelling and institutionalized elderly in Hong Kong.

OBJECTIVE: The study investigated the experience of orofacial pain (OFP) symptoms and associated disability and psychosocial impact in community dwelling and institutionalized elderly people in Hong Kong. METHODS: A community-based cross-sectional survey involving elders aged 60 years and above. Participants were recruited at social centres for the elderly and homes for the aged throughout Hong Kong. Elders who reported OFP symptoms in the previous four weeks took part. Standard questions were asked about OFP conditions in the previous month and the Manchester Orofacial Pain Disability Scale (MOPDS), the Oral Health Impact Profile (OHIP-14) and the General Health Questionnaire (GHQ-12) were administered. The MOPDS was translated and validated for use in Chinese elders. RESULTS: 200 community dwelling and 200 institutionalized elders participated. Toothache was the most common symptom (62.0%) and burning sensation in the tongue was least common (0.5%). The distribution of pain symptoms, pain duration and severity and pain ratings were similar in both groups. The MOPDS (Chinese elders version) had good reliability and construct validity. The MOPDS and OHIP-14 summary scores was significantly higher in the institutionalized elderly (p < 0.001 and p < 0.013, respectively). Psychological distress (GHQ-12 score > or = 4) was more common among the institutionalized elderly (11%) than the community dwelling elderly (4.0%, p = 0.002). CONCLUSIONS: Orofacial pain symptoms were associated with significant disability and had a detrimental impact on psychological distress level and quality of life, particularly in the institutionalized elderly. There is a need to improve access to professional care and health-related outreach services generally for elderly people in Hong Kong.

Translation and validation of the Hindi version of the Geriatric Oral Health Assessment Index.

PURPOSE: To translate the original English version of the Geriatric Oral Health Assessment Index (GOHAI) into Hindi and assess its validity and reliability for use among people in India. MATERIALS AND METHOD: After translation into Hindi, a total of 385 participants aged 55+ demonstrated acceptable validity and reliability when used for people in India. Individual GOHAI items were recorded and summed as originally recommended. The questionnaire sought information about socio-demographic characteristics and self-reported perception of general and oral health. Clinical examination included assessment of periodontal status and number of decayed teeth, missing teeth, filled teeth and crowned teeth. RESULT: Mean GOHAI score was 40.9 (SD, 10.6; range, 12-60). Cronbach's alpha for the GOHAI score was 0.88, indicating a high degree of internal consistency and homogeneity between the GOHAI items. The test-retest correlation coefficient for add-GOHAI scores was 0.72, indicating good stability. Add-GOHAI scores increased with poorer perceived general and oral health. Convergent validity, construct validity and discriminant validity of the GOHAI were demonstrated. CONCLUSION: It could therefore be used as a valuable instrument for measuring oral health-related quality of life for people in this region.

Validity and reliability of patient-centered outcome measures in oral dysesthesia.

OBJECTIVE: The objective of this study was to investigate the validity and reliability of a quality of life instrument in patients with oral dysesthesia. STUDY DESIGN: Forty-five individuals newly diagnosed with oral dysesthesia (37 women, 8 men) were enrolled in this study. Individuals were interviewed using the Visual Analogue Scale (VAS), and the Oral Health Impact Profile (OHIP-14). Construct validity and internal reliability were examined. RESULTS: Patient rating of pain experienced, using VAS, correlated with OHIP-14 scores (P < .05), demonstrating construct validity. OHIP-14 demonstrated good internal consistency with Cronbach's alpha of 0.79. The corrected item-total correlations for items 3 (painful aching) and 12 (difficulty doing usual jobs) were below the recommended minimum of 0.20. Cronbach's alpha increased to 0.81 with the exclusion of these 2 items from OHIP-14. CONCLUSIONS: The OHIP-14 questionnaire appeared to perform relatively well in the 45 patients with oral dysesthesia enrolled in this study, demonstrating validity and reliability in the assessment of the effect of oral dysesthesia on quality of life. However, the exclusion of items 3 and 12 from the questionnaire should be considered in future studies with this patient population.

Evaluation of salivary cortisol and psychological factors in patients with oral lichen planus.

BACKGROUND AND OBJECTIVES: Lichen planus is a relatively common chronic inflammatory disease of oral mucosa and skin. Cortisol, also called as "stress hormone", has been used as an indicator in various stress evaluation studies. Salivary cortisol measurement is an indicator of free cortisol or biologically active cortisol in human serum and provides noninvasive and easy technique. Recent studies have been conflicting, and hence, in the present study, evaluation of salivary cortisol levels and psychosocial factors in oral lichen planus (OLP) patients was done. MATERIALS AND METHODS: A total of 30 patients with clinically and histopathologically proven cases of OLP, along with the age and sex-matched healthy controls were included in the study. Samples of stimulated saliva were collected, centrifuged and analyzed for the level of cortisol with cortisol enzyme linked immunosorbent assay. Psychosocial factors of study and control groups were measured by depression anxiety and stress scale. Student's t-test was used to compare the psychological factors and salivary cortisol levels between patients with the OLP and the control group. RESULTS: Irrespective of sex, significantly higher depression (83.4 +/- 15.4%), anxiety (80.5 +/- 11.3%), and stress (94.2 +/- 6.2%) scores were observed in OLP patients compared to controls. Increased cortisol levels were observed among 17 (56.6%) OLP patients in the study group. A positive correlation was found between psychological factors and salivary cortisol levels in the OLP patients. The values of Pearson's correlation coefficient "r", between depression, anxiety, and stress with salivary cortisol was: +0.42,S; +0.27,NS; and +0.65,HS, respectively among the study group.

Clinical psychiatric assessment of patients with burning mouth syndrome resisting oral treatment.

Of 100 consecutive patients referred for investigation of symptoms related to oral galvanism, 18 with persisting symptoms of burning mouth syndrome (BMS) remained after investigation and treatment (Hugoson 1986). In addition to the oral and medical treatment, 16 (14 women, 2 men) of these patients underwent psychiatric investigation. The results of this investigation are presented in this report. The psychiatric investigation was performed as a semistructured interview, elucidating current symptoms, the patient's opinion as to the onset and causes, previous illnesses and psycho-social conditions. Two hours were reserved for each patient interviewed with the aim of obtaining a holistic picture of each individual. The patients with refractory burning mouth syndrome did not differ from the others with respect to oral status, salivary secretion or calculated galvanic currents. No patient had burning mouth as the only symptom, all reporting many symptoms from different organs. Three patients had had symptoms for at least 20 years, 9 for 5-10 years and 4 patients for less than 4 years. Seven patients related the onset of symptoms to oral treatment. Thirteen of the patients reported one or more medical diagnoses and 10 patients were taking 1-3 medicines. Ten patients reported significant negative experiences in connection with previous contacts with the health services and several considered themselves wrongly diagnosed and treated. Most of the patients had experienced catastrophes in their lives in the form of stillborn children or children born with various handicaps, children injured in accidents or prolonged social problems. One patient was judged to have somatic causes of the symptoms, 8 patients somatic and psychological causes, 6 patients psychological causes and in 1 patient the cause was unknown. Three cases are presented in more detail.

Psychophysical assessment of tactile, pain and thermal sensory functions in burning mouth syndrome.

Tactile, two-point discrimination, thermal change detection and heat pain thresholds as well as oral stereognostic ability, warmth scaling and heat pain tolerance were compared in a group of 72 subjects with burning mouth syndrome (BMS) and 43 age- and sex-matched control subjects. No differences were found between the BMS and control subjects for any of the sensory modalities tested except for heat pain tolerance. Pain tolerance was significantly decreased for the BMS subjects at the tongue tip, a site of clinical pain in approximately 85% of the subjects tested in this study, but not at the cutaneous lower lip which was a site of pain only in approximately 17% of the subjects tested in this study. In addition, no differences in heat pain tolerance were found at the cutaneous lower lip between the control subjects and the BMS subjects who reported pain on the mucosal lower lip (approximately 49% of subjects), but heat pain tolerance was significantly decreased at this site for those BMS subjects tested without pain on the mucosal lower lip (approximately 51% of subjects). These findings do not suggest a psychogenic origin for the alteration of heat pain tolerance in the BMS subjects, but suggest instead specific changes in their peripheral or central sensory functions.
