简要总结

The aims of this study are: To compare salivary pH changes and stimulation efficacy of two different Gustatory Stimulants of Salivation (GSSS) in patients with Primary Sjögren Syndrome (PSS); To evaluate Primary Sjögren syndrome (PSS) impact and gustatory stimulants of salivary secretion (GSSS) on oral health related quality of life measured by a Portuguese version of Oral Health Impact Profile-14 (OHIP-14) and specific Xerostomia assessment questionnaires.

The Products to be used are the Xeros® Dentaid system and a citric based mouthwash.

研究组 & 干预措施

Xeros Group - Lozenge

Experimental

Application of Xeros system for 15 days. Lozenge (Malic acid 28.56 mg, Xylitol 421,98 mg, Sodium fluoride 0.55 mg) or Spray (Malic acid 1%, Xylitol 10%, Sodium fluoride 0.05%) 4 times a day. Effects on Xerostomia and Quality of Life were determined before and after application by answering the questionnaires.

Effects of lozenge on hyposalivation and pH variation determined by saliva collection with pre-weighed falcon and a ph electrode at predetermined times during a 20 minute period.

干预措施: Xeros (Drug)

Mouthwash group

Active Comparator

Application of citric acid based Mouthwash (0,33% citric acid) for 15 days four times a day. Effects on Xerostomia and Quality of Life were determined before and after application by answering the questionnaires.

Effects of mouthwash on hyposalivation and pH variation determined by saliva collection with pre-weighed falcon and a pH electrode at predetermined times during a 20 minute period.

干预措施: Citric Acid based Mouthwash (Drug)

Xeros Group - Mouthwash

Experimental

Application of Xeros system for 15 days. Mouthwash (Betaine 1.33%, Xylitol 3.30%, Sodium fluoride 0.05%, Allantoin 0.10%) 2 times a day.

Effects on Xerostomia and Quality of Life were determined before and after application by answering the questionnaires.

干预措施: Xeros (Drug)

Xeros Group - Gel

Experimental

Application of Xeros system for 15 days. Gel (Betaine 1%, Aloe Vera 0.05%, Xylitol 10%, Sodium Fluoride 0.0033%) before bed.

Effects on Xerostomia and Quality of Life were determined before and after application by answering the questionnaires.

干预措施: Xeros (Drug)

Xeros Group - Toothpaste

Experimental

Application of Xeros system for 15 days. Toothpaste (Betaine 4%, Xylitol 10%, Sodium Fluoride 0.33%, Allantoin 0.10%) 3 times a day.

Effects on Xerostomia and Quality of Life were determined before and after application by answering the questionnaires.

干预措施: Xeros (Drug)

结局指标

主要结局

Overall and sub domains scores for each questionnaire

时间窗: 15 days

Before and after usage of both products at home, the Summated Xerostomia Inventory-5 (range 0 to 15) to measure subjective feeling of dry mouth, Oral Health Impact Profile-14 (range 0 to 56) to measure quality of life perception related to the oral cavity. This last questionnaire is further divided into 7 subdomains: functional limitation, physical pain, psychological discomfort, physical disability, psychologic disability, social disability and handicap each ranging from 0 to 14. In both questionnaires the total score is the result of the sum of the individual scores in each question. In both questionnaires the higher the score the worse the outcome. The before and after scores obtained are then compared.

Time of GSSS induced pH drop below 4.5

时间窗: 20 minutes

On the day that the system is attributed the subject is asked to use one of the products and saliva is collected. pH variation is determined at fixed intervals during 20 minutes. Time in which salivary pH is below 4.5 is calculated as well as the number needed to treat and the absolute risk reduction.

次要结局

  • Salivary stimulant induced salivary flow(20 minutes)
