- InterventionsThe study is designed as a single - blind (examiner) randomized two-arm parallel clinical trial. Pre- and post mesaurments will be carried out:
1. The control group will rinse with 15 milliliter water for 30 seconds;
2. The intervention group will drink 200 milliliter water.
- Primary outcomeThe primary outcome is Moring Bad Breath (MBB) and will be measured by three different methods:
1. Organoleptic score:
The judge is using an arbitrary 0-5 scale (Rosenberg et al. 1991a, Rosenberg et al. 1991b further modiefied by Greenman et al. 2004). The 0 represented absence of odour, 1 was given for barely noticeable odour, 2 for slight odour, 3 for moderate odour, 4 for strong odour and 5 for extremely strong odour;
2. Halimeter:
We are using a portable industrial sulphide monitor (Halimeters, Interscan Corp., Chatsworth, CA, USA). The unit is zeroed to ambient air before each measurement, using the technique established by Rosenberg et al. (1991a, b);
3. OralChroma assessments:
A portable gas chromatography (OralChroma«) using a flame photometric detector is the preferable method if precise measurements of specific gases are required. This technology is specifically designed to digitally measure molecular levels of the three major VSC (H2S, CH3SH, and dimethyl sulfide CH3SCH3).

In total there will be three different measurments to express the level of MBB.
- Secondary outcome1. Tongue coating index:
The procedure to assess coating is a modification of the method as described by Miyazaki et al. (1995) and described in detail by Mantilla Gomez et al. (2001);
2. Enquete: subjects give their opinions about their experience of this clinical trial.

- Brief summaryTo reduce the Morning Bad Breath (MBB) several websites suggest that rinsing or drinking water upon awakening is effective. Since MBB can be caused by a dry mouth. Water drinking help to stimulate the saliva production and saturate the whole mouth. Rinsing seems like the obvious first-aid measure to take (consumer websites). This home-remedy is however not supported with scientific evidence.
