Analgesic effect of topical oral capsaicin gel in burning mouth syndrome.

OBJECTIVE: To investigate the effectiveness of repeated topical application of oral capsaicin gel in two different concentrations for relief of burning/stinging sensations in patients with burning mouth syndrome (BMS). MATERIAL AND METHODS: This randomized double-blind cross-over study included 22 female patients with BMS. The patients were randomized for topical application of either 0.01% or 0.025% oral capsaicin gel on the dorsal part of tongue three times daily for 14 days, followed by 14 days wash-out period, and finally treatment with the other concentration of oral gel three times daily for 14 days. A visual analogue scale (VAS) was used to assess the severity of pain five times during the intervention period. RESULTS: 18 patients completed the intervention. Their VAS score at baseline was 5.5 ± 0.6 cm (mean ± SD). Treatment with the two concentrations of capsaicin gels significantly improved the burning/stinging symptoms assessed on VAS compared with baseline (p = 0.002). There was no statistically significant difference between the two concentrations of the gels on relieving symptoms. Four patients dropped out during the intervention period due to gastrointestinal side-effects. CONCLUSIONS: Topical capsaicin might be an alternative for the short-term treatment of BMS. However, further studies are needed to investigate especially the gastro-intestinal side-effects which may limit its long-term use.

Evaluation of the efficacy of two mouthrinses formulated for the relief of xerostomia of diverse origin in adult subjects.

OBJECTIVE: To evaluate the efficacy of two new mouthrinses in the reduction of xerostomía-associated symptomatology. BACKGROUND: Xerostomia is a common chronic health condition that affects a great number of adults and significantly deteriorates quality of life, such that treatment is necessary. MATERIALS AND METHODS: Sixty-seven adult subjects of both sexes presenting xerostomia of diverse origin were selected. Mouthrinses were tested using a double-blind, randomized, cross-over clinical trial with an intervining wash out period. RESULTS: The 100% of subjects presented sensation of dry mouth, and 86% stated sensation of thick saliva. Burning tongue sensation, need to drink liquids to swallow and the sensation of swallowing difficulty were recorded in more than 50% of the patients. The most frequent pathologies in the sample were depression, arthritis, and arterial hypertension. Results of the clinical tests showed that mouthrinse 1 relieves sensation of dry mouth, need to drink liquids, and swallowing difficulty. In contrast, mouthrinse 2 relieves only latter two symptoms. Both rinses were more effective in relieving xerostomía-associated symptomatology in patients taking 3 or more medicines simultaneously. CONCLUSION: Both mouthrinses were effective in relieving various xerostomia symptoms, could be distributed at a low cost, thereby improving the quality of life of population affected.

Vulvostomatodynia.

Burning mouth syndrome associated to vulvodynia (Vulvostomatodynia) is a rare condition and is often difficult to diagnose and treat. Tongue, lips, vestibule and others mucosal sites may be affected by a tiresome burning sensation, especially in menopausal and postmenopausal women. Patients seldom report genital symptoms to the dentist and dentists do not generally investigate about genital symptoms. Delays in diagnosis may affect the quality of life. We report the clinical features of five new cases of vulvostomatodynia. A thorough multidisciplinary medical management is necessary to improve symptoms and prevent from psychologic distress. Counselling and an understanding between patient and clinician/therapist are important for long-term results.

[Burning-mouth syndrome: consideration of maintenance factors]. / Het syndroom van mondbranden: aandacht voor instandhoudende factoren.

Burning-mouth syndrome is characterised by a number of complaints of which the burning sensation in the mouth is the most important but cannot be explained by known medical causes. Although psychological factors can predispose for or trigger physical symptoms without a medical explanation, treatment directed at the proposed psychological causes has not proven to be very effective and is not acceptable for most patients. Treatment directed at reducing the consequences of the complaint that could play a role in maintaining the problem is, however, effective and is accepted by almost all patients. Consequences that could maintain the burning-mouth syndrome are anxiety, depression, selective attention, and measures taken to find relief but which can irritate the oral mucosa. The treating physician should inform the patient and help him to change his behaviour. If patients have become depressed or very anxious as a consequence of the complaints they should be referred to a cognitive-behaviour therapist specialised in the treatment of patients with physical symptoms without a medical explanation.

Saliva substitute in xerostomic patients with primary Sjögren's syndrome: a single-blind trial.

OBJECTIVE: To evaluate the efficacy of oral moisturizing gel (Oral Balance) in xerostomic patients with primary Sjögren's syndrome (SS). METHOD AND MATERIALS: Twenty-one xerostomic patients with primary SS were subjected to a single-blind trial in which the efficacy of Oral Balance gel in reducing xerostomia and xerostomia-related oral symptoms was compared with that of a placebo. Both gels were packaged identically and were indiscernible in appearance and taste. Xerostomia was confirmed for all the patients through measurement of stimulated whole saliva. Patients began using the Oral Balance gel three times a day for 90 days, and were then switched to a gel placebo to be used in the same way for the same length of time. Clinical response was evaluated through the patients' subjective assessment (improved, worsened, or unaltered) of both gels. RESULTS: Neither the Oral Balance gel nor the gel placebo affected the salivary output of the patients. The Oral Balance gel presented a substantial statistically significant advantage in the control of burning mouth, mastication, and swallowing. No statistically significant relief of the isolated sensation of oral dryness was established. CONCLUSION: Oral Balance is a useful tool in the management of dryness-related oral symptoms in primary SS, but there is room for enhancing the overall properties of topical preparations designed to reduce oral complaints in xerostomic patients.
