ABSTRACT
OBJECTIVE: The aim of this study was to determine the efficacy of a chamomile (Matricaria chamomilla) and linseed (Linum usitatissimum) saliva substitute in the relief of xerostomia in older participants. BACKGROUND: In elders, xerostomia is a permanent and progressive condition that significantly affects their quality of life. The treatment for progressive xerostomia is currently restricted to palliative measures, and saliva substitutes are indicated. A lack of evidence on the effectiveness of the saliva substitutes in the relief of symptoms of xerostomia has been reported. MATERIALS AND METHODS: Seventy-four elderly participants presenting xerostomia of diverse origin were selected. Herbal saliva substitute and carboxymethyl cellulose conventional saliva substitute were tested using a double-blind, randomised, cross-sectional clinical trial. RESULTS: Every participant of the study exhibited dry mouth sensation. A sensation of thick saliva was described in 59.5% of the participants. The need for liquid intake to swallow food, the sensation of difficulty in swallowing and the burning sensation in the tongue were observed in 54.1, 56.8 and 27.0% of the participants, respectively. The most prevalent diseases were hypertension, depressive symptoms and arthritis. Results of the clinical tests showed that the herbal saliva substitute produced a greater relief of dry mouth symptoms, thick saliva sensation and the sensation of difficulty in swallowing than the conventional substitute (Wilcoxon test p < 0.05). CONCLUSIONS: New chamomile- and linseed-based saliva substitute was effective in relieving xerostomia symptoms in older participants of this study.

OBJECTIVE: This study was conducted to establish associations among the Candida carriage rate, the diversity of Candida species carried and the different caries status of preschool children. MATERIALS AND METHODS: Sixty-one children between 2 and 5 years of age were examined by a single expert examiner and were divided into three groups, the caries-free, moderate caries and severe caries groups, according to the criteria of the International Caries Detection and Assessment System II (ICDAS). Saliva samples were obtained from the members of each group and were plated on Sabouraud agar plates to assess the Candida carriage rates. CHROMagar Candida medium was used for the preliminary screening. Biochemical testing or PCR/sequencing was conducted to identify the different Candida species in the samples. The differences observed were considered significant if the p value was <0.05. RESULTS: The Candida carriage rate and the number of species of this fungus carried were higher in the group with the highest level of caries severity (p < 0.05). Whereas Candida albicans was the most predominant Candida species in the saliva of all of the children, C. dubliniensis was identified only in the most caries-affected group in addition to other rare species of Candida non-albicans. CONCLUSIONS: A high salivary Candida carriage rate and the presence of specific species of this fungus (such as C. albicans and C. dubliniensis) appear to be related to the severity of caries experienced by preschool children.

Introducción: La xerostomía es una condición crónica que afecta a un alto porcentaje de adultos mayores, que deben ser tratados paliativamente mediante el uso de sustitutos salivales; sin embargo estos productos no se encuentran disponibles en el mercado nacional. Objetivos Evaluar la eficacia de un nuevo sustituto salival a base de manzanilla y semillas de linaza en la disminución de la sintomatología asociada a xerostomía en individuos adultos mayores. Metodología Se incluyeron 34 voluntarios adultos mayores con xerostomía de diverso origen. Un nuevo sustituto salival a base de manzanilla y semillas de linaza y un sustituto convencional a base de carboximetilcelulosa fueron testados en un ensayo clínico aleatorizado, cruzado, con período de blanqueamiento. Resultados El 100 por ciento de los sujetos presentó sensación de boca seca, el 58,8 por ciento sensación de saliva espesa, el 52,9 por ciento necesitaba beber líquidos para deglutir los alimentos y tenía sensación de dificultad para tragar. La sensación de ardor lingual se registró en el 23,5 por ciento de los individuos. Las enfermedades más frecuentes en la muestra analizada fueron la hipertensión arterial y la artritis. Los resultados del ensayo clínico indican que el sustituto salival a base de manzanilla y semillas de linaza disminuye significativamente la sensación de boca seca y la sensación de saliva espesa (test de Wilcoxon p < 0,05). Conclusión El nuevo sustituto salival a base de manzanilla y semillas de linaza es efectivo en el alivio de la sintomatología asociada a xerostomía en adultos mayores, por lo que puede contribuir a mejorar la calidad de vida de la población afectada por esta condición.
Introduction: Xerostomia is a common chronic health condition that affects a great number of elderly people. Palliative treatment, such as salivary substitutes should be used, but these products are not accessible in the Chilean market. Objectives To evaluate the efficacy of a new Chamomile and linseed based saliva substitute in the reduction of xerostomía-associated symptomatology in elderly people. Methodology Forty elderly subjects presenting with xerostomia of various origins were selected. Chamomile and linseed based saliva substitute and a carboxymethylcellulose based conventional artificial saliva were tested using a double-blind, randomized, cross-over clinical trial with an intervining wash out period. Results All (100 percent) of subjects had a sensation of dry mouth, and 58.8 percent mentioned a sensation of thick saliva, 52.9 percent needed to drink liquids to swallow, and with a sensation of swallowing difficulty. Burning tongue sensation was recorded in 23.5 percent of the patients. The most frequent pathologies in the sample were arterial hypertension and arthritis. Results of the clinical tests showed that Chamomile and linseed based saliva substitute significantly relieves the sensation of dry mouth and the sensation of thick saliva (Wilcoxon test P < .05). Conclusion New chamomile and linseed based saliva substitute was effective in relieving xerostomia symptoms in elderly people, and could improve the quality of life of population affected by this condition.
